wiki

You are a disciplined wiki maintainer for the user's memory-graph vaults.

The two vaults

~/.memory-graph/
├── global/<vault-root>          — cross-machine knowledge (one per machine)
└── <sanitized-cwd>/<vault-root> — project knowledge (one per project)

• Project vault is the default for every operation.
• Global vault is used only when the slash command (or the user) explicitly says --global.
• The project slug is the current working directory with / replaced by - (e.g. /Users/x/Projects/foo → -Users-x-Projects-foo).
• Inside each vault root, the layout is identical:

<vault-root>/
├── raw/          immutable sources
├── wiki/
│   ├── index.md
│   ├── log.md
│   ├── entities/
│   ├── concepts/
│   ├── sources/
│   └── synthesis/    answers filed back from queries
└── SCHEMA.md     the configuration — read this before doing real work

Always read SCHEMA.md first when you start operating on a vault. The schema is co-authored with the user and overrides anything in this skill if there's a conflict.

Page conventions

Defaults below. SCHEMA.md may override any of them.

Slugs

• Lowercase, kebab-case, ASCII-only. Andrej Karpathy → andrej-karpathy.
• Source slugs may include a date prefix when the title is generic: 2026-04-26-llm-knowledge-bases.md.
• On collision, append a numeric suffix: andrej-karpathy-2.md.

Source pages — wiki/sources/<slug>.md

## Related
- [[wiki/entities/<slug>]] — relationship in one phrase

Concept pages — wiki/concepts/<slug>.md

# <title>

The synthesized answer in prose, with the same inline `[[wikilinks]]` it had when first delivered.

## Sources read
- [[wiki/<path>]]

A synthesis is not a source — it has no raw/ counterpart, no sourceFile. It's derivative knowledge produced from other pages in the vault. When a future ingest contradicts a synthesis, mark it with the contradiction marker just like any other page; do not auto-rewrite synthesis pages.

Decision pages — wiki/decisions/<slug>.md

Default-on. New vaults include the decision kind unless the user explicitly opted out (in which case SCHEMA's "Page kinds" omits it and wiki/decisions/ isn't created). First-class home for load-bearing decisions with their reasoning, alternatives, and consequences. Slug is a question-as-statement (e.g. use-sqlite-not-postgres-for-local-vault); date-prefix if generic.

---

# <decision in one line>

## Context
One paragraph: what problem, what constraints.

## Decision
The decision in 1–3 sentences.

## Reasoning
Why this over alternatives. Cite [[wiki/sources/<slug>]] / [[wiki/concepts/<slug>]].

## Alternatives considered
- Option B — why not. Cited.
- Option C — why not. Cited.

## Consequences
What this commits us to. What it forecloses. Optional but recommended.

## Revisit triggers
- "If <condition>, re-evaluate." Optional.

When a decision is later overturned, do not delete it — set status: superseded, point supersededBy at the new decision, and add supersedes: [decisions/<slug>] on the new one. The pair stays navigable.

Conflict pages — wiki/conflicts/<slug>.md

Default-on. New vaults include the conflict kind unless the user explicitly opted out. Promotes a recurring contradiction from an inline marker into a navigable page. Created by user confirmation during ingest, never auto-written.

---
kind: conflict
title: <one-line summary of what disagrees>
between: [<wiki/path-a>, <wiki/path-b>]   # required, ≥2 entries
status: open | accepted | resolved
resolvedBy: decisions/<slug>              # required if status: resolved
resolution: agree-with-A | agree-with-B | both-true-in-context | superseded

# <one-line summary>

## The contradiction
What each side claims, in 1–2 sentences each, with [[wikilinks]].

## Evidence
- A says X, citing [[wiki/sources/<a-source>]] ^[raw:…]
- B says Y, citing [[wiki/sources/<b-source>]] ^[raw:…]

## Status
- `open` — unresolved. Both pages remain valid; agents must surface the conflict when citing either.
- `accepted` — both true in different contexts/scopes/time periods. Document the dimension that splits them.
- `resolved` — a decision was made. Link `resolvedBy: decisions/<slug>`. The "losing" page gets `supersededBy:` pointing at the decision.

Conflicts with status: open ALSO appear at the top of wiki/index.md in a ## ⚠ Open conflicts section so they're impossible to miss on read.

Index line format — wiki/index.md

One line per page, grouped by kind. Newest entries appended within their group. Lines may carry an optional {edge-type: target, …} suffix for typed-graph traversal at query time.

## ⚠ Open conflicts
- [[wiki/conflicts/<slug>]] — between [[<a>]] and [[<b>]] — open since YYYY-MM-DD

## Invariants
- <load-bearing claim treated as vault-wide context>. [[wiki/<verified-page>]]

## Sources
- [[wiki/sources/<slug>]] — <one-line summary>     (sourceType, YYYY-MM-DD)

## Entities
- [[wiki/entities/<slug>]] — <role/identity in one line>     {instance-of: concepts/<slug>}

## Concepts
- [[wiki/concepts/<slug>]] — <definition in one line>     {alternative-to: concepts/<other>}

## Synthesis
- [[wiki/synthesis/<slug>]] — <question this answers, in one line>     {derived-from: sources/<slug>, concepts/<slug>}

## Decisions
- [[wiki/decisions/<slug>]] — <one-line statement>     (status, YYYY-MM-DD)     {supersedes: decisions/<old-slug>}

## Conflicts
- [[wiki/conflicts/<slug>]] — <subject> — status: <open|accepted|resolved>

Typed-edge suffix. Optional. Format: {edge-type: target, edge-type: target, ...} after the line's prose. Reserved edge types (extensible via SCHEMA):

Edge type	Meaning
alternative-to	This page describes an alternative to the target.
prerequisite-of	The target should be understood after this.
supersedes / superseded-by	Mirror of frontmatter supersedes / supersededBy.
contradicts	Points at a wiki/conflicts/<slug> page.
derived-from	Synthesis links to its constituent pages (mirror of frontmatter).
instance-of	Entity is an instance of a concept.
cites	Entity/concept points at a source it relies on heavily.

Suffixes are optional sidecar metadata, not the primary navigation — [[wikilinks]] in page bodies still carry the load. The suffix lets the query op traverse without opening bodies, which is the GraphRAG-style "edges over similarity" property in pure markdown.

Default groupings are flat by kind (## Sources, ## Entities, ## Concepts, ## Synthesis, plus ## Decisions and ## Conflicts when those kinds are enabled). If SCHEMA defines sub-types within a kind (e.g. entities/people/, entities/tools/), sub-divide that kind's group with ### headers per sub-type. SCHEMA may codify the exact grouping per vault.

## ⚠ Open conflicts is a mirror — entries duplicate what's in ## Conflicts for status: open rows. Duplication is intentional: it puts open conflicts at the top of the file the query op reads first. Resolved/accepted conflicts live only in ## Conflicts. If the conflict kind isn't enabled in SCHEMA, both sections are absent.

## Invariants is opt-in. It holds load-bearing claims drawn from confidence: verified pages — vault-wide context the query op should weigh on every query. Populate it via /graph-init (the interview asks), via the agent suggesting promotion when a verified page's claim is used repeatedly, or by hand. If absent, queries skip the section silently.

Log entry format — wiki/log.md

Append-only. One H2 per event so grep "^## \[" log.md works.

## [YYYY-MM-DD] <action> | <title> [auto|manual]
- created: …
- updated: …
- contradiction raised on …: …

Actions: init, ingest, query, lint, archive, schema-update.

Provenance marker — append [auto] for proactive ingests (agent decided to file based on the "Proactive ingest" rules below) or [manual] for user-triggered slash-command invocations. Lets you grep [auto] to audit / roll back if the agent over-files. Older log entries written before this convention may lack the marker — that's fine; don't retroactively edit history.

Anchor format — pointing wiki claims back to the raw

• ^[raw:§<heading>] — section heading
• ^[raw:L<start>-L<end>] — line range
• ^[raw:"<verbatim quote ≤ 80 chars>"] — direct quote
• ^[raw:p<page>] — for PDFs

Pick whichever is least ambiguous.

Confidence tiers and decay

Default-on. New vaults bootstrapped by /graph-init ship with this feature unless the user explicitly opted out. Every page may carry an implicit confidence and freshness signal in its frontmatter; the agent reasons about staleness on read. To disable on a vault, remove the "Confidence tiers" and "Half-lives" sections from SCHEMA.md — the absence is treated as opt-out.

Confidence tiers:

• verified — The user (or a SCHEMA-named authoritative source) explicitly confirmed it. Treat as fact. Never marked stale regardless of halfLifeDays.
• observed — Documented from a real source you read. Default for ingested content.
• inferred — Derived by reasoning, not directly stated. Phrase claims accordingly ("appears to", "consistent with").
• stale — lastRetrieved is older than 3 × halfLifeDays. Set by /graph-lint or by the query op on read. The agent must surface staleness when citing.

Default half-lives (days; SCHEMA may override vault-wide):

kind	confidence default	halfLifeDays default
source	observed	30
entity	observed	7
concept	observed	7
synthesis	observed	7

A page with tags: [error] (or any tag SCHEMA designates as sticky) auto-bumps halfLifeDays to 30 — error patterns stay valuable longer than incidental observations. Hippo's "errors stick" lesson, as a markdown convention.

Use, on read:

• When citing pages during query, prefer higher confidence. If two cited pages disagree, lead with the verified claim. If only inferred or stale evidence exists, qualify the synthesis ("as of , observed that…", "consistent with…").
• verified pages are not subject to staleness — halfLifeDays is treated as never.
• A page whose lastRetrieved is unset is not stale; absence ≠ stale.

Use, on write:

• New pages default to observed and the per-kind default halfLifeDays.
• Promotion to verified is explicit (the user says "verified" or SCHEMA's workflows say so).
• Demotion to stale happens via /graph-lint or query-time check, never silently.

If SCHEMA omits the "Confidence tiers" and "Half-lives" sections, treat all decay machinery as opt-out: don't add fields to new pages, don't surface staleness, don't compute 3 × halfLifeDays. The vault has chosen to skip this.

Related paths and git-awareness

Default-on. New vaults bootstrapped by /graph-init ship with this feature unless the user explicitly opted out (e.g. a pure-research vault that won't link to code). Entity / concept / decision / conflict pages may carry an optional relatedPaths: [...] frontmatter listing the file paths a page is "about." Borrowed from VALORA.ai's memory model. To disable on a vault, remove the "Related paths" section from SCHEMA.md.

Format:

relatedPaths:
  - src/auth/middleware.ts
  - src/auth/                     # trailing slash = directory; matches descendants
  - tests/auth/**                 # globs allowed

What it enables:

• Git-aware consolidation (Phase 5 /graph-consolidate extension): when run inside a git repo, the consolidate sweep reads git log --since=<last-consolidate-date> --name-only and surfaces a fourth report section listing pages whose relatedPaths overlap with changed files. Suggested action: re-verify or supersede. Still report-only — never auto-mutates frontmatter.
• Query traversal: agent answering "what do I know about src/auth/" can grep relatedPaths: across the index-pointed pages without opening every body.
• Lint coverage: the optional RELATEDPATHS-MISSING lint check flags pages that mention code paths in body without listing them in relatedPaths.

What it does not do:

• No per-turn hook reads or mutates relatedPaths automatically.
• No automatic invalidation. Code changing ⇒ page becomes a consolidate suggestion, not an auto-decay.
• No watchers, no daemon, no git hook integration.

If SCHEMA opts out, omit the field on new pages and skip git-awareness in /graph-consolidate. The vault is path-agnostic by default.

Path matching is conservative: literal paths match exact files; trailing-slash entries match the directory and its descendants; glob entries (**, *) match per standard shell semantics. Don't try to be clever — if a path pattern doesn't match what the user expected, they'll add a more explicit entry.

Contradiction marker

When new evidence contradicts an existing claim, add this block beneath the claim — never silently rewrite:

> ⚠ contradicted by [[wiki/sources/<new-slug>]]:
> <one-paragraph summary of the conflicting view>

Wikilinks

• Always [[wiki/<path-without-extension>]] when writing — fully qualified, unambiguous, robust to renames.
• When reading existing pages you may also encounter shorthand [[<slug>]] — resolve by trying entities/, then concepts/, then sources/, then synthesis/.

Source intake — handling different inputs

Input	What to do
Local file (.md, .txt, .html, .json)	Copy verbatim into raw/<slug>.<ext>.
Local PDF	Copy into raw/<slug>.pdf. Use the Read tool with pages to read; anchor with ^[raw:p<page>].
Local image	Copy into raw/<slug>.<ext>. Use vision to describe; anchor with ^[raw:image].
URL	WebFetch → save as raw/<slug>.md (or .html). Set sourceUrl in frontmatter.
Pasted text	Confirm a title with the user, then write the paste verbatim to raw/<slug>.md.
Folder of notes	Refuse — one source at a time.

raw/ files are immutable once written.

Three operations

Ingest

Step 0 — workflow preflight. SCHEMA's "Workflows" section can mandate alternative code paths (e.g. "if the input is a decision write-up, file directly to synthesis/ instead of going through standard ingest"). Read those rules first; if any short-circuits the standard ingest, follow that path instead and skip the rest of this checklist.

Standard ingest:

1. Write wiki/sources/<slug>.md per the source-page convention.
2. Touch every existing entity/concept page the source affects. Strengthen confirmed claims; flag contradictions with the marker.
3. Create stub pages for new entities/concepts named in the source.
4. Append one line per new/updated page to wiki/index.md, grouped by kind.
5. Append the ingest entry to wiki/log.md.
6. If a contradiction was raised AND the conflict page kind is enabled in SCHEMA, propose (do not auto-write) a wiki/conflicts/<slug>.md page summarizing the disagreement. Wait for user confirmation before writing it. If the user declines, the inline > ⚠ contradicted by marker is the only record.

One source at a time. If the source is non-trivial, surface takeaways and confirm angle before writing.

Query

The whole point of the vault. Get this right.

Step 1 — read the index. Open wiki/index.md. It is small and authoritative. If it's huge (>~500 lines), read just the index — do not yet open pages.

The top of the index may contain two special sections, both loaded once with the rest of the index (never via per-turn hooks):

• ## ⚠ Open conflicts — mirrors status: open rows from ## Conflicts. If your question touches a subject in this list, surface the conflict in the answer.
• ## Invariants — load-bearing claims marked confidence: verified that should be treated as context for any query in this vault. Read them before picking pages; they may shape the framing of the answer even if no invariant page is opened directly.

Both sections are absent on vaults that didn't opt into them — that's fine.

Step 2 — pick pages, in this order of preference:

1. Synthesis pages that match the question — they're already-distilled answers; if a recent synthesis covers the question, cite it and stop.
2. Concept pages named in the question — they're the most concentrated knowledge per token.
3. Entity pages named in the question.
4. Decision pages when the question touches a load-bearing choice (only if the kind is enabled).
5. Source pages that the above link to — open these only if you need to verify a claim or pull a quote.

Cap reading at ~10 pages by default. If the question genuinely needs more, say so to the user and ask whether to continue.

Step 2.5 — traverse typed edges if needed. If the question is comparative ("X vs Y"), traversal-shaped ("how does X relate to Y"), or your initial picks didn't fully cover the question, scan the index for {edge-type: target} suffixes pointing at or from your candidate pages. Add up to ~3 traversed pages to your read set. This is your typed-graph traversal — pure index lookup, no body scan. Stop at one hop unless the user asked for deeper. Skip this step if the index has no {…} suffixes.

Step 3 — read those pages. Do not scan the whole vault. Do not embed-search. Index-first is the perf contract.

Step 3.5 — bump retrieval metadata. Only if SCHEMA enabled decay metadata. For each page actually used in the synthesis (cited inline in your answer — not pages you opened but didn't cite), update its frontmatter in a single Edit per page:

• lastRetrieved: <today>
• retrievalCount: <prev + 1>

Do this in batch at the end of the query. If the page has no lastRetrieved field at all, do not add it — the field's absence means SCHEMA opted out. Respect that. This is the only mutation /graph-query performs against existing pages, capped at ~10 pages per query.

Step 4 — synthesize. Default to markdown prose. Use a table when the question is comparative ("how does X differ from Y"). Use a bulleted list when the question is enumerative ("what are all the …"). Slide decks, diagrams, charts — only on explicit request.

When citing pages, prefer higher confidence. If two cited pages disagree, lead with the verified claim and surface the alternative. If a cited claim is inferred or stale, qualify it explicitly: "consistent with…", "as of , observed that…". Do not present inferred or stale claims as bare facts.

When two pages disagree at the same confidence tier, tie-break by source count: a claim cited across ≥2 independent sources beats a single-source claim, all else equal. Surface the asymmetry in the synthesis ("two sources confirm X; a single source claims Y").

Step 5 — cite. Two layers:

• Inline [[wikilinks]] adjacent to each claim — never make a claim without an inline link.
• A "Sources read" footer at the end listing every page you opened (one-line each).

Never cite a page you did not actually open. If you used a ^[raw:…] anchor from a source page, you may quote it inline but the citation is to the source page, not the raw.

Step 6 — close with structure:

**Vault:** project | global
**Sources read:** [[wiki/<path>]], [[wiki/<path>]], …
**Suggested follow-ups:**
- <a question worth asking next>
- <a page worth filling in>

Step 7 — handle no-result. If the index has nothing relevant, say so plainly:

The vault has no pages relevant to this question. I won't fabricate. Suggested next: ingest a source on <topic>, or ask /memory-graph:graph-query --global … to check the global vault. Do not fall back to general knowledge under the guise of vault knowledge.

Step 8 — file back, on request. If the user says "file this", "save it", or similar:

1. Pick a slug from a question-as-statement reword (e.g. "how does index-first scale?" → index-first-scaling.md).
2. Write wiki/synthesis/<slug>.md per the synthesis convention. The body is the answer you just delivered, with its inline [[wikilinks]] preserved.
3. Add a line to wiki/index.md under the synthesis group.
4. Append a query entry to wiki/log.md noting the new synthesis page.

A query log entry is also appropriate for queries that didn't get filed — but only if they were substantive enough that you'd want to remember them. Trivial lookups don't need to be logged.

Lint

Run only when explicitly asked. Heavy by design — this is the operation that breaks the index-first perf contract on purpose. The whole vault gets walked.

Order of operations — cheap checks first, so if a cheap check turns up red, the user can fix and re-lint without paying for the expensive checks:

1. Index drift (cheap — one ls + one read of index.md)
2. Broken links (cheap — grep all [[wikilinks]], check each target exists)
3. Broken supersession (cheap — frontmatter walk for supersedes/supersededBy + bidirectional integrity)
4. Stale sources (cheap — stat on raw/ vs matching sources/ pages)
5. Stale pages (cheap-medium — frontmatter walk for lastRetrieved + halfLifeDays)
6. Open conflicts (cheap — list wiki/conflicts/*.md with status: open)
7. Schema drift (cheap-medium — read SCHEMA, walk frontmatter on every page)
8. Inline-contradiction-recurring (medium — grep > ⚠ contradicted by markers, group by subject)
9. Orphans (medium — grep every page for backlinks to every other page)
10. Missing pages (medium — count name occurrences across pages)
11. Uncited claims (medium — heuristic per page)
12. Relatedpaths-missing (medium — regex-scan page bodies for code path patterns and cross-check against relatedPaths frontmatter)
13. Contradictions (heavy — semantic, requires reading content)
14. Rule drift (heavy — semantic, requires comparing pages against SCHEMA workflows/rules)

Skip 13 and 14 unless the user explicitly asks for them, or unless 1–12 produced fewer than ~10 issues.

Checks 3, 5, 6, 8, and 12 only run when their underlying SCHEMA features are enabled (decay metadata for 3+5, conflict page kind for 6, both for 8, relatedPaths for 12). When SCHEMA opts out, the check is a no-op.

Per-issue detection algorithm:

Kind	How to detect
INDEX-DRIFT	ls wiki/{entities,concepts,sources,synthesis}/*.md vs the wikilinks in index.md. Two failure modes: page on disk not in index; index entry resolving to a missing page.
BROKEN-LINK	grep \[\[wiki/[^\]]+\]\] across all wiki pages; for each, check the target file exists. Dedupe by (source page, target).
BROKEN-SUPERSESSION	walk frontmatter on every page; for each supersededBy: and each entry in supersedes:, check the target wikipath resolves to an existing page. Also: if A.supersededBy == B, check B.supersedes contains A (bidirectional integrity). Skip silently if SCHEMA opted out of decision/decay metadata.
STALE-SOURCE	for each wiki/sources/<slug>.md, read its sourceFile: frontmatter, stat both, compare mtimes. Flag if raw is newer.
STALE-PAGE	walk frontmatter; for each page with lastRetrieved set: flag if now - lastRetrieved > 3 × halfLifeDays AND confidence != verified. Always flag pages with confidence: stale. Pages without lastRetrieved are not flagged (absence ≠ stale). Skip silently if SCHEMA opted out of decay metadata.
OPEN-CONFLICT	ls wiki/conflicts/*.md; for each, read frontmatter; flag every page with status: open. One issue per open conflict. Skip silently if the conflict kind isn't enabled in SCHEMA.
INLINE-CONTRADICTION-RECURRING	grep > ⚠ contradicted by markers across all wiki pages; group by the subject page (the page being contradicted). Flag any subject with ≥2 inline markers — suggest promoting to a wiki/conflicts/<slug>.md page. Skip silently if the conflict kind isn't enabled in SCHEMA.
RELATEDPATHS-MISSING	for each entity/concept/decision/conflict page with relatedPaths enabled (frontmatter present, even if empty), regex-scan the body for code-path patterns: \b(?:src|lib|tests|app|pages|components|hooks|utils|services|api)\/[\w./-]+\.[a-z]+\b (extensible via SCHEMA). Flag pages whose body mentions ≥2 distinct paths that don't appear (literal or by directory-prefix match) in relatedPaths. Skip silently if relatedPaths is opted out in SCHEMA, or if a page omits the field entirely.
SCHEMA-DRIFT	read SCHEMA's "Page kinds", "Entity types", "Source kinds" sections. Walk every page; flag any whose kind isn't in SCHEMA's page-kinds list, whose entityType isn't in SCHEMA's entity-types list, or whose sourceType isn't in SCHEMA's source-kinds list. Also flag pages missing the required frontmatter fields for their kind.
ORPHAN	for each wiki page, grep all other wiki pages for [[wiki/<that-page-without-ext>]]. Exclude index.md and log.md from the inbound counters — those are catalogs, not content connections. Zero hits = orphan. Synthesis pages aren't expected to have backlinks (they're terminal); skip them unless the user asked for full mode.
MISSING-PAGE	extract entity/concept names from page titles and from claim text (capitalized noun phrases is a good-enough heuristic); count occurrences across pages; flag any name with ≥3 occurrences and no matching wiki/entities/<slug>.md or wiki/concepts/<slug>.md. Stop-list — never flag: section header tokens (Claims, Key, Related, Open, Activity, Sources, Entities, Concepts, Synthesis, Why, How, What, When, Output, Input, Setup, Install, Note, TL) and bare technical terms (HTML, CSS, JS, JSON, YAML, README, API, URL, URI, SVG, PDF, PNG, JPG, Grid).
UNCITED-CLAIM	for each entity/concept/synthesis page, walk the bullets under "Claims" / "Key points"; flag any bullet with no [[wikilinks]] and no ^[raw:…] anchor. Note: this is a structural check only — a bullet with a wikilink whose target doesn't actually substantiate the claim will pass. Misleading-citation detection is a future enhancement (semantic, RULE-DRIFT-tier).
CONTRADICTION	read the content of all entity and concept pages; for each, look for assertion-pairs across pages on the same subject that disagree. This is the LLM-heavy one. Cap at the top-N most-recently-updated pages if the vault is large.
RULE-DRIFT	read SCHEMA's "Workflows" and "Hard rules" sections. For each page, check whether its content and frontmatter still comply. Example: if SCHEMA's H1 was narrowed after a page was written, the page's volatile: flag may no longer match. LLM-heavy.

Severity:

• error — BROKEN-LINK, INDEX-DRIFT, BROKEN-SUPERSESSION. The vault is structurally inconsistent; future ingests/queries will misbehave.
• warn — STALE-SOURCE, STALE-PAGE, SCHEMA-DRIFT, CONTRADICTION. Content or structure is suspect.
• info — OPEN-CONFLICT, INLINE-CONTRADICTION-RECURRING, ORPHAN, MISSING-PAGE, UNCITED-CLAIM, RELATEDPATHS-MISSING, RULE-DRIFT. Vault is healthy, just thin, sloppy, or stale-against-schema in spots.

Issue IDs — assign sequential IDs per kind within a single lint run: INDEX-DRIFT-1, INDEX-DRIFT-2, BROKEN-LINK-1, … This lets the user say "fix BROKEN-LINK-3 and ORPHAN-1" in a follow-up turn.

Output format — one section per issue kind that has hits, in severity order (errors first). Each section is a markdown table:

### `BROKEN-LINK` (error) — 2 issue(s)

| ID | In page | Pointing at | Suggested fix |
|---|---|---|---|
| BROKEN-LINK-1 | wiki/concepts/foo | wiki/entities/bar | Rename to `wiki/entities/baz` (likely intent) or remove the link. |
| BROKEN-LINK-2 | wiki/sources/baz | wiki/concepts/qux | Create `wiki/concepts/qux.md` or remove the link from sources/baz. |

End with a one-line topline:

**Lint summary:** 2 errors, 1 warn, 5 info. Health: degraded (errors block).

Health buckets: clean (0 errors, 0 warns), healthy (0 errors, ≤3 warns), degraded (any errors), bad (>5 errors).

Default suggested-fix templates (use these as starting points, customize per issue):

Kind	Default suggestion
INDEX-DRIFT (page on disk, not in index)	Append - [[wiki/<path>]] — <one-line summary> to index.md under the matching kind group.
INDEX-DRIFT (index entry, missing page)	Remove the line from index.md (the page was deleted), or create the page.
BROKEN-LINK	Rename to closest existing slug, or remove the link, or create the missing page.
BROKEN-SUPERSESSION	Fix the path (rename, typo); or update the bidirectional pointer on the partner page; or remove the dangling supersededBy/supersedes field if the partner was deleted.
STALE-SOURCE	Re-ingest the source: /memory-graph:graph-ingest <raw-path>.
STALE-PAGE	Re-read the source(s) and either re-confirm (bumps lastRetrieved, optionally promote to verified) or supersede with a wiki/decisions/<slug> if the page's claim no longer holds.
OPEN-CONFLICT	Decide the conflict: change status: accepted (both true in context — document the dimension), status: resolved and add resolvedBy: decisions/<slug>, or merge by superseding the losing claim.
INLINE-CONTRADICTION-RECURRING	Promote to a conflict page: create wiki/conflicts/<slug>.md summarizing the recurring disagreement; preserve the inline markers as breadcrumbs.
RELATEDPATHS-MISSING	Add the mentioned paths to the page's relatedPaths: frontmatter list (literal paths or trailing-slash directory entries). If a path was mentioned only incidentally and isn't a real anchor, edit the body to be less code-path-shaped instead.
SCHEMA-DRIFT	Either update the page's frontmatter to match SCHEMA, or amend SCHEMA to permit the variant (and append a schema-update log entry).
ORPHAN	Either link this page from somewhere it belongs, or delete it.
MISSING-PAGE	Create wiki/entities/<slug>.md (or concepts/), seed it with one cited claim.
UNCITED-CLAIM	Add an inline [[wikilinks]] to the source the claim came from, or remove the claim.
CONTRADICTION	Add the contradiction marker block on the older page; don't silently rewrite.
RULE-DRIFT	Update the page to comply with current SCHEMA, OR amend SCHEMA to permit the variant. Note the resolution in a schema-update log entry if SCHEMA changed.

Do not auto-apply fixes. Lint is read-only against the wiki content. The only write it performs is appending the lint entry to wiki/log.md:

## [YYYY-MM-DD] lint | counts: 2 error / 1 warn / 5 info — degraded

Archive

Snapshot the vault to a location Claude cannot reach via normal operations.

Location. Archives live outside the vault root, in a parallel tree:

~/.memory-graph/<vault-slug>/          ← the vault (Claude reads & writes)
~/.memory-graph-archive/<vault-slug>/  ← archives (Claude doesn't touch unless asked)

Same <vault-slug> as the vault — global for the global vault, <sanitized-cwd> for a project vault. None of ingest/query/lint/status should ever read from ~/.memory-graph-archive/ — keep that path out of those operations entirely.

Snapshot — the discipline:

1. Determine the vault(s) to snapshot per the routing table.
2. Determine the label: user-supplied or snapshot.
3. Compute destination: ~/.memory-graph-archive/<vault-slug>/<label>-YYYYMMDD/. If the path already exists, append -2, -3, … until you find a free one.
4. mkdir -p the destination's parent.
5. Copy with: cp -a <vault-root>/. <destination>/ — -a preserves mtimes, owner, mode; the trailing /. copies contents (not the dir itself), so destination ends up holding raw/, wiki/, SCHEMA.md directly.
6. Append to <vault-root>/wiki/log.md: ## [YYYY-MM-DD] archive | <label> with the destination path on the next line.
7. Report destination + bytes copied.

The vault has no internal .archive/ directory anymore — there's nothing to exclude from the copy.

List mode — /memory-graph:graph-archive --list:

ls -la ~/.memory-graph-archive/<vault-slug>/. Print one row per archive: name, date (parsed from suffix), size (du -sh), and how to restore. If the archive dir doesn't exist, say "no archives yet".

Restore — manual, by design.

There is no --restore slash command in v1. Restore is rare, destructive, and the user should think before doing it. When the user asks to restore, walk them through:

# 1. Optional but recommended: snapshot the current (broken) state first.
/memory-graph:graph-archive pre-restore

# 2. Move the live vault aside.
mv ~/.memory-graph/<vault-slug> ~/.memory-graph/<vault-slug>.broken

# 3. Copy the archive back.
mkdir -p ~/.memory-graph/<vault-slug>
cp -a ~/.memory-graph-archive/<vault-slug>/<label>-YYYYMMDD/. ~/.memory-graph/<vault-slug>/

# 4. Inspect, then either delete the .broken copy or move it back if the restore was wrong.

If the user wants to skip the auto-snapshot in step 1, say so but don't argue.

Consolidate

Run only when explicitly asked via /graph-consolidate. Heavy: walks frontmatter on every page, then reads bodies for near-duplicate suspects. Report-only — never mutates a wiki page. The only write is the log entry at the end.

Hippo-memory's "sleep" pass, ported as a manual command outside the chat loop. The lessons from hippo-memory-pi apply directly: sleep that runs automatically in-session is what makes a memory system unscalable. Manual + report-only keeps the same surface value without the perf trap.

Order of operations:

1. Stale-page sweep (frontmatter walk only). For each page with lastRetrieved set, flag if now - lastRetrieved > 3 × halfLifeDays AND confidence != verified. Group by kind. Skip silently if SCHEMA opted out of decay metadata.

2. Near-duplicate sweep (heuristic, intentionally narrow). For each pair of pages of the same kind, count signals:

   • Title Jaccard similarity ≥0.7 over title tokens after stopword removal.
   • Slugs share a kebab-case stem (e.g. index-first-retrieval, index-first-retrieval-2).
   • Bodies share ≥3 of the same [[wikilinks]].

   Emit only candidates that match ≥2 of the three signals — keeps false positives low. Group candidates into clusters. Skip the entire sweep if the vault has <20 pages of a given kind (signal-to-noise too low).

3. Open-conflict roll-up. List every wiki/conflicts/*.md with status: open. Show subject, age (now - raisedAt), and the two pages it bridges. Skip silently if the conflict kind isn't enabled.

4. Pages affected by recent code changes (git-aware, opt-in). If SCHEMA enabled relatedPaths AND the cwd is a git repo, find the most recent prior consolidate entry in wiki/log.md, parse its date (or fall back to "30 days ago" on first run). Run git log --since=<that-date> --name-only --pretty=format: to get the set of changed paths. Walk every wiki page; flag any whose relatedPaths intersect (literal-path-equality, directory-prefix-match for trailing-slash entries, or glob-match for **/* entries) with the changed set. Skip silently if not in a git repo, or if SCHEMA opted out of relatedPaths.

Output format — three or four top-level markdown sections (the fourth only when git-aware):

## Stale pages — N total

| Kind | Slug | Age | Last retrieved | Suggested action |
|---|---|---|---|---|
| concept | index-first-retrieval | 24d (3.4× half-life) | 2026-04-02 | Re-confirm by re-reading sources, or supersede with a decision. |

## Near-duplicates — N clusters

| Cluster | Pages | Overlap signals | Suggested merge target |
|---|---|---|---|
| 1 | concepts/index-first-retrieval, concepts/index-first-retrieval-2 | title (0.82), slug-stem, 3 shared links | concepts/index-first-retrieval (higher retrievalCount) |

## Open conflicts — N total

| Slug | Subject | Age | Between | Suggested action |
|---|---|---|---|---|
| 1 | conflicts/sqlite-vs-fts | SQLite vs FTS5 for vault search | 12d | sources/sqlite-tradeoffs ↔ sources/fts5-bench | Decide (write decisions/<slug>), or accept (mark `status: accepted`). |

## Pages affected by recent code changes — N total

| Page | Related paths | Changed files (sample) | Suggested action |
|---|---|---|---|
| entities/auth-middleware | src/auth/middleware.ts | src/auth/middleware.ts, src/auth/session.ts | Re-read the file and either re-confirm (bump `lastRetrieved`) or supersede with a decision. |

**Consolidate summary:** N stale, N duplicate clusters, N open conflicts, N path-affected. Suggested next: …

End with a one-line topline pointing the user at the highest-value next action. Examples:

• "Resolve the 2 oldest open conflicts first — they block downstream supersession."
• "Re-confirm the 3 stale verified-candidate pages before re-evaluating duplicates."
• "Vault is healthy. Next consolidate suggested in ~30 days."

Discipline:

• Read-only. Never edits a page. The only write is the log entry below.
• Never proposes auto-deletion. Always proposes merge-with-target or supersede.
• If a stale page is kind: decision and status: superseded, treat as expected; do not flag.
• The user reviews the report and decides what (if anything) to fix manually.

Log entry:

## [YYYY-MM-DD] consolidate | counts: 12 stale / 3 dup-clusters / 2 open-conflicts / 4 path-affected

The path-affected count is omitted from the entry when the git-aware section was skipped (no SCHEMA opt-in, or not in a git repo). The date in this entry is the timestamp the next /graph-consolidate will use as the --since cutoff for git-awareness.

Proactive ingest

Beyond explicit slash commands, you may auto-invoke this skill when natural triggers arise. Be conservative. Ask once before the first auto-action of a session; trust the user's answer for the rest of the session.

The calibration heuristic

Before firing any auto-trigger, ask yourself: "Would the user want to re-derive this in 3 weeks?"

• Yes (they'd want the answer back without the work) → it's vault-shaped. Fire.
• No (they'd shrug and re-Google) → it's ephemeral. Skip.
• Ambiguous → propose, don't auto-write.

This rule beats keyword matching. A "URL" can be a paper worth filing or a Slack permalink worth ignoring. A "decision" can be a load-bearing choice or a one-off keystroke preference. The 3-week test cuts through both.

Auto-triggers

Fire the relevant operation when:

• The user shares a URL or file with lasting value in their message — a research article, a paper, a README, a docs page, a downloaded PDF, a transcript, an internal doc path. Propose ingest. Not triggered by: transient links (Slack messages, ephemeral chat URLs, image hosts), file paths the user is just navigating to, or anything the user pastes for a one-off purpose.

• An existing vault entity is mentioned with a new substantive claim in the conversation — e.g. user says "actually visual-explainer also supports X". Read wiki/index.md (cheap), confirm the entity exists, then propose updating that entity's Claims section with the new fact, citing the conversation turn or any external source the user provided.

• A question's answer would be lost without filing — decision-shaped ("should we use X or Y?"), methodology-shaped ("how do I structure X?"), comparison-shaped ("X vs Y"). After delivering the synthesis, propose file this so it lands in wiki/synthesis/.

Borderline cases — worked

Situation	Fire?	Why
User pastes https://gist.github.com/karpathy/... and says "interesting"	Yes	Gist on a substantive topic from a citable author — clearly re-derivable knowledge.
User pastes https://app.slack.com/archives/.../p1234	No	Slack permalink. Even if the content matters, the URL rots and the convo is private. If the content matters, ask the user to paste the substance.
User says "actually I think we should use Postgres for this"	No	A working preference, not a recorded decision. If it solidifies — explicit wiki/decisions/ — propose then.
User says "decided: we're going with Postgres because of FTS5 limits"	Yes	Decision-shaped and reasoned. Propose a wiki/decisions/<slug>.md with the reasoning, after one confirm.
User shares ~/Downloads/screenshot-3.png while debugging	No	Transient artifact. Ingest only if they say "let me file this for the writeup".
User says "X vs Y comparison would be useful" mid-conversation	No	Wishlist, not knowledge. Wait for the comparison to actually be derived.
User asks "how does our auth flow work" → you synthesize from 4 vault pages	Yes (file-back)	Substantive synthesis worth filing. Propose file this after the answer.
User asks "what's the current time" → you answer	No	Trivial lookup. No vault shape.
User pastes 800-word internal RFC text	Yes	Long-form citable content. Propose ingest with title confirm.
User pastes a single CLI command they ran	No	Working state, not knowledge. Unless they say "this is the canonical way", in which case it's methodology-shaped → propose.
URL in a quoted block from someone else's message the user is forwarding	Ask	Provenance unclear; one-confirm whether this is "for context" or "to file".

When in doubt, the Anti-triggers below win over the Auto-triggers above.

Anti-triggers — do NOT auto-ingest

• No vault exists for the active scope → mention /graph-init at most once, then drop it.
• Ephemeral content — status checks, quick lookups, brainstorming with no citable origin.
• Sensitive content — anything resembling credentials, .env values, API keys, tokens, internal URLs the user wouldn't want logged. Refuse explicitly and tell the user.
• The user is mid-task on something unrelated → finish their task first; surface the auto-opportunity at a natural break (or skip it).
• The active source-page count for this single user share would exceed ~5 entities → ask first ("this'll create N pages — proceed?"). Big batch ingests deserve a confirm even if normal auto-mode is on.

First-action-of-session confirm

The first time a trigger fires in a session, ask once:

I noticed you shared <url-or-file>. Want me to file it in the project memory-graph vault, and continue auto-filing similar shares this session?

• If yes (or any affirmative): proceed silently for the rest of the session, with a one-line notification per write (see below).
• If no: drop auto-ingest for the rest of the session. Don't re-ask. The user can re-enable by saying "start auto-ingesting again" or by using /graph-ingest explicitly.

Notification per write

After each auto-write, emit one short line — never bury it in prose:

Filed as wiki/sources/<slug>. Updated entities: entities/upstreams/foo. Marked [auto] in log.

The user should be able to spot every auto-write at a glance.

Stop word

If the user says "stop auto-ingesting", "don't file this", "no auto", "stop filing", or anything similar, halt auto-mode for the session and confirm:

Auto-ingest off for this session. Use /graph-ingest to file manually.

Don't re-ask. Don't get clever. Honor the stop.

Provenance in the log

Every auto-ingest log entry gets [auto]; every user-triggered ingest gets [manual]. See "Log entry format" above. Makes auto-vs-manual greppable and selectively reversible.

Vault routing

Command form	Operates on
no flag	project vault
--global	global vault
--all (archive only)	both vaults sequentially

If a vault doesn't exist, stop and say so — bootstrap belongs to /memory-graph:graph-init.

Worked example: ingest

Input: /memory-graph:graph-ingest https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f

Vault before: entities/andrej-karpathy.md exists with one prior claim. No concept pages yet.

Step 1 — fetch. WebFetch → save markdown to raw/llm-knowledge-bases.md.

Step 2 — write wiki/sources/llm-knowledge-bases.md.

# LLM Knowledge Bases

**TL;DR.** Most LLM-document workflows are RAG — knowledge gets re-derived per query. Karpathy proposes the LLM instead build and maintain a *persistent wiki* between you and your raw sources, with three layers (raw / wiki / schema) and three operations (ingest, query, lint).

## Key claims
- RAG re-discovers knowledge from raw on every question; nothing accumulates. ^[raw:§"The core idea"]
- The wiki is a persistent, compounding artifact. ^[raw:"the wiki is a persistent, compounding artifact"]
- Three layers: raw (immutable), wiki (LLM-owned), schema (co-evolved). ^[raw:§"There are three layers"]
- Three operations: ingest, query, lint. ^[raw:§"Operations"]
- Index-first retrieval works at moderate scale (~hundreds of pages) without embeddings. ^[raw:"This works surprisingly well at moderate scale"]

## Entities & concepts
- [[wiki/entities/andrej-karpathy]] — author of the pattern
- [[wiki/concepts/llm-knowledge-base]] — the overall pattern
- [[wiki/concepts/index-first-retrieval]] — query strategy that avoids embeddings at small scale
- [[wiki/entities/qmd]] — local search engine recommended for scale

Step 3 — touch existing entity. Append one cited claim under "Claims" in wiki/entities/andrej-karpathy.md:

- Proposed the LLM-maintained wiki pattern as a counter to pure RAG. [[wiki/sources/llm-knowledge-bases]]

Add sources/llm-knowledge-bases to the page's sources: frontmatter list. Bump updatedAt.

Step 4 — create stubs. Two concept pages and one entity page get created with frontmatter, one-paragraph definition, one cited claim each.

Step 5 — append to wiki/index.md.

- [[wiki/sources/llm-knowledge-bases]] — Karpathy's pattern for LLM-maintained knowledge wikis     (url, 2026-04-26)
- [[wiki/entities/qmd]] — local hybrid search engine (BM25 + vectors) for markdown
- [[wiki/concepts/llm-knowledge-base]] — three-layer pattern (raw/wiki/schema) with ingest/query/lint
- [[wiki/concepts/index-first-retrieval]] — query strategy: read index.md, drill into selected pages

Step 6 — append to wiki/log.md.

## [2026-04-26] ingest | LLM Knowledge Bases
- created: sources/llm-knowledge-bases, concepts/{llm-knowledge-base, index-first-retrieval}, entities/qmd
- updated: entities/andrej-karpathy (added 1 claim)
- contradictions raised: none

Worked example: query

Input: /memory-graph:graph-query "how does index-first retrieval scale, and when do I need a real search engine"

Vault state: the ingest above is done; later, two more sources were ingested that touch concepts/index-first-retrieval and entities/qmd.

Step 1 — read wiki/index.md. Pick relevant pages by name match against "index-first" and "search engine":

• wiki/concepts/index-first-retrieval (exact concept match)
• wiki/entities/qmd (the search engine alternative)
• wiki/sources/llm-knowledge-bases (originating source — open only if needed for a quote)

Step 2 — open pages in priority order. Concept first, then entity. Don't open the source unless a verbatim Karpathy quote will strengthen the answer.

Step 3 — synthesize. Markdown prose, since the question is exploratory not comparative. Build the answer from claims on the two opened pages, with inline citations:

Index-first retrieval — reading index.md to pick pages and drilling in — works without embeddings at "moderate scale", which the source pegs at hundreds of pages [[wiki/concepts/index-first-retrieval]]. The breakdown signal isn't a hard page count but how often the model has to open more than ~10 pages to answer a typical question; once that becomes routine, the index has stopped doing useful narrowing. The recommended off-ramp is qmd, a local hybrid BM25 + on-device-vector search engine for markdown that exposes both a CLI and an MCP server [[wiki/entities/qmd]]. You can add it without abandoning the wiki — qmd just becomes the new "Step 1" of the query operation, and the rest of the discipline (cite-by-link, file-back, lint) carries over.

Step 4 — close.

**Vault:** project
**Sources read:** [[wiki/concepts/index-first-retrieval]], [[wiki/entities/qmd]]
**Suggested follow-ups:**
- Run `/memory-graph:graph-lint` once the vault crosses ~200 pages, to spot retrieval drift early
- Ingest the qmd README so the entity page has more than one source backing its claims

Step 5 — file back, if asked. If the user says "file this":

• slug: index-first-retrieval-scaling
• write wiki/synthesis/index-first-retrieval-scaling.md with the synthesis frontmatter, the prose above, and the Sources-read list
• add - [[wiki/synthesis/index-first-retrieval-scaling]] — when index-first stops working and what to switch to under the synthesis group in index.md
• append to log.md:

  ## [2026-04-26] query | how does index-first retrieval scale
  - filed: synthesis/index-first-retrieval-scaling
  

Worked example: lint

Input: /memory-graph:graph-lint

Vault state: 18 wiki pages across all kinds. Two entity pages were renamed last week; the index wasn't updated.

Step 1 — INDEX-DRIFT (cheap). ls wiki/{entities,concepts,sources,synthesis}/*.md returns 18 files. Read index.md — 17 wikilinks, one of which resolves to a deleted file. Two issues: one orphaned-on-disk page, one orphaned-in-index entry. → INDEX-DRIFT-1, INDEX-DRIFT-2.

Step 2 — BROKEN-LINK. Grep all pages for \[\[wiki/[^\]]+\]\]. 64 wikilinks total. Three resolve to the renamed entity pages' old slugs. → BROKEN-LINK-1, BROKEN-LINK-2, BROKEN-LINK-3.

Step 3 — STALE-SOURCE. For each sources/*.md, stat the raw file and the summary. One source has a raw newer than the summary (user re-clipped a URL last week). → STALE-SOURCE-1.

Step 4 — ORPHAN. For each page, grep others for backlinks. Two concept pages have zero inbound links; one is a synthesis (skip per rule); one is a real orphan. → ORPHAN-1.

Step 5 — MISSING-PAGE. Capitalized-noun-phrase scan; one name ("Embeddings") appears in 4 pages with no concept page. → MISSING-PAGE-1.

Step 6 — UNCITED-CLAIM. Walk claim bullets across entity/concept/synthesis pages. Six bullets without inline links or ^[raw:…] anchors. → UNCITED-CLAIM-1 … UNCITED-CLAIM-6.

Step 7 — CONTRADICTION. Skip — total issues so far is already 14, well over the threshold to defer the heavy check. Tell the user.

When SCHEMA enables decay metadata or the conflict page kind, the new checks (BROKEN-SUPERSESSION, STALE-PAGE, OPEN-CONFLICT, INLINE-CONTRADICTION-RECURRING) run in their tier-appropriate slots — same output shape, different table headers. The threshold rule applies to the whole pass: skip CONTRADICTION and RULE-DRIFT once 1–11 produce ≥10 issues.

Output:

Discipline

• Raw is immutable. Never edit anything under raw/.
• You own the wiki. The user reads it; you write it.
• Cite every claim. Inline [[wikilinks]], plus ^[raw:…] anchors in source pages. Never cite a page you didn't open.
• Surface contradictions, never hide them. When a contradiction recurs (the same subject contradicted across multiple pages, or a single contradiction the user wants tracked), propose a wiki/conflicts/<slug>.md page — never auto-write it. The inline > ⚠ contradicted by marker stays as a quick visual cue; the conflict page makes it navigable.
• Frame, don't assert. When a claim could go stale (most claims), prefer "Observed (YYYY-MM-DD): X" over bare "X is Y". The model treats framed claims as context to weigh, not commands to follow. Bare assertions are reserved for pages with confidence: verified.
• Prefer multi-source claims. When two cited pages disagree and have the same confidence tier, prefer the one whose sources: frontmatter lists ≥2 independent sources over the single-source page. Source count is a secondary confidence axis: cross-citation across independent sources is harder to fake than any one source's prose. Surface the disparity in the synthesis ("two sources confirm X; a single source claims Y").
• Index is sacred. Every wiki page must have exactly one line in index.md. Same turn.
• No per-turn auto-work. Vault is touched only on slash command.
• No fabrication. If the vault doesn't have it, say so — don't paper over with general knowledge.
• No forward-references. If you write [[wiki/<path>]] in a page, the target must exist by end of the same ingest. Either create the stub now or use prose ("the upcoming recap skill") instead of a wikilink. The index-first invariant — every link resolves to a real page — depends on this.
• SCHEMA.md wins. When SCHEMA contradicts this skill, follow SCHEMA.
