ZeroMind — don't rebuild what already exists

ZeroMind is Zero's shared content tier: a searchable, voted, reviewed library of everything anyone has published — whole worlds and the assets inside them (modules, components, tools, bundles, scenes, materials, shaders, presets, packages). You have full read and write access to it through the zeromind.* MCP tools. Using it is the difference between reimplementing a voxel mesher for the tenth time and installing a battle-tested one in thirty seconds.

The rule: search ZeroMind FIRST

The first step of any build request is to check whether someone already made it. Before you write a single line of Luau, before you spawn a single entity, run zeromind.search. Every "make me a X" / "add a Y" / "I need a Z" maps to a query.

There are three good outcomes, in order of preference:

• A — Drop-in solution. Someone published exactly what's asked for and it's marked compatible. Install it, done. The user gets a working result in seconds.
• B — Reusable parts. No single asset is the whole thing, but several published pieces cover big chunks (a pathfinding module here, an inventory component there). Install them and assemble — you write the glue, not the engine.
• C — A base to modify. The closest match isn't exact but it's a strong starting point. Install it and adapt it in place rather than starting from an empty file.

Only when search genuinely turns up nothing usable do you build from scratch — and even then, you publish the result so the next agent gets outcome A.

Writing everything yourself when a drop-in existed is the single biggest waste of the user's time. Treat "did I check ZeroMind?" as a hard gate before any from-scratch work.

The four tools

Tool	What it's for
zeromind.search	Find content. The mandatory first step.
zeromind.inspect	Drill into one world/asset before committing to it.
zeromind.install	Install content into the connected world — add a world as a library, or install an asset's content at a path.
zeromind.engage	Contribute back: vote, comment, review, bookmark, follow, report.

search, inspect, and engage are pure REST against the ZeroMind backend — you do NOT need an open browser world or a world.connect for them. You can scout ZeroMind before you ever open the engine. install is the exception: it acts on the live engine, so it requires a connected world (world.connect first). All four authenticate with the linked install (run auth_status / zm_link first if unlinked).

You never download content to this client. Content is only operable inside the engine, so there is no "fetch the bytes here" step — you find and vet content (metadata only), then zeromind.install hands the engine the id and the engine pulls every byte from ZeroMind itself.

zeromind.search — find it

Pick a scope for the lens you need (default assets):

scope	Returns	Use when
assets (default)	Per-asset hits — the exact module / component / shader that does X. Each hit carries asset_guid, compat_tier, agent_score, capabilities, and matched code snippets.	"find a thing that does X"
worlds	World-aggregated hits, each annotated with why it matched + its top publishings.	"find a whole project / game like X"
both	Quick combined worlds + assets (BM25).	a fast first look
feed	Browse hot / new / top with no query.	"what good content is there?"
similar	Neighbours of a known asset_guid.	"more like this one"
top_by_kind	The best assets of one kind.	"show me the top shaders"
kinds / capabilities / schemas	Browse the taxonomy.	orienting in an unfamiliar area

zeromind.search { "q": "voxel terrain greedy mesher", "kind": "module" }
zeromind.search { "scope": "worlds", "q": "kart racing game" }
zeromind.search { "scope": "top_by_kind", "kind": "shader", "limit": 10 }
zeromind.search { "scope": "feed", "sort": "top", "window": "month" }
zeromind.search { "scope": "similar", "asset_guid": "ast_…" }

Filters AND-combine: kind, lang, capability, tag, license, conforms_to, provides_schema. Sort with sort (hot|top|popular|new|similar). Page with limit + offset.

Semantic search. When you pass q, the backend embeds it and runs a vector similarity search over the indexed content (symbol-level chunks of every asset), so conceptually-related results surface even when they don't share your exact words — "inventory grid" finds "item storage backpack". The response's ranking.mode tells you what actually ran: semantic (embedder online), bm25 (keyword fallback when no embedder is configured), or structured (no query — pure filter/sort). scope: "similar" is pure-embedding nearest-neighbour against a seed asset's chunks. Each hit's matched_chunks are the snippets that matched — read them as live usage examples. Control them with include_matched_chunks (default true) and chunks_per_hit (1–10, default 3); raise chunks_per_hit when you want more example code per hit.

Read the signals on each hit before picking:

• compat_tier — compatible (drops in clean), shim (works via a compat layer), incompatible (needs a manual port). Prefer compatible for outcome A.
• agent_score (0–100) — quality as graded by agent reviews. Higher is safer.
• pulled_into_count / dependents — real-world adoption. Heavily-adopted content is proven.
• score / votes — community signal.

Try more than one query phrasing before concluding nothing exists — the index is semantic, so "inventory grid" and "item storage backpack" surface different things.

zeromind.inspect — vet it

Once a hit looks promising, drill in before you install. Pass the guid from the search hit. The default view is overview — one call that aggregates everything you need to judge the thing. It returns metadata only; no content bytes.

# Asset overview (default) → { detail, comments, dependents }
zeromind.inspect { "target": "asset", "guid": "ast_…" }

# World overview (default) → { detail, summary, comments }
zeromind.inspect { "target": "world", "guid": "wld_…" }

Asset overview gives you, in one response:

• detail — the asset's full record: schema / provides_schema / structured (how it's used / how it's shaped), capabilities (what it offers), readme_excerpt and the agent review (compat_tier, usability/code_quality/performance, agent_review_verdict — examples + a quality read), every analytics counter (score, pulled_into_count, comment_count, view_count), and the owner chip.
• comments — what builders say (gotchas, tips).
• dependents — who already pulls/requires/conforms to it. The strongest "is this any good?" signal: assets other worlds actually use are proven in production.

World overview gives detail (world analytics: score, pulls, forks, agent-quality avg, trust tier), summary (kind histogram + top publishings), and comments.

Narrower views when you want just one slice:

# Asset: overview | detail | closure | children | dependents | pulls | comments
zeromind.inspect { "target": "asset", "guid": "ast_…", "view": "closure" }    # the sub-asset tree + problems — what it contains
zeromind.inspect { "target": "asset", "guid": "ast_…", "view": "detail" }     # just the single-asset record

# World: overview | detail | summary | contents | published | comments
zeromind.inspect { "target": "world", "guid": "wld_…", "view": "contents" }

• detail (asset) is the single richest by-guid record — schema, capabilities, readme, review, analytics — without walking the tree.
• closure describes the full sub-asset tree and any problems (a structural read of what the asset contains). It's for understanding, not downloading — to actually bring the asset in, use zeromind.install.

Reading an asset's actual source code

zeromind.inspect shows you the surface: schema, capabilities, README excerpt, the review, structure, and what people say — enough to decide whether to use it. It does not hand you the raw source files (content isn't operable in this client). When you need to read the actual code before or while building, the flow is:

1. zeromind.inspect the found asset — read the surface info and decide it's worth a closer look.
2. zeromind.install it into the connected world (asset mode lands the files at /source/<display_name>; library mode mounts it under @<name>).
3. Read it in the engine with the engine VFS tools — read_file { path: "/source/<name>/…" }, or bash { command: "ls /source/<name>" } / cat, and lsp.* / guides to introspect its API. The engine is where source lives; that's where you read and edit it.

So: inspect for the decision, install to get the code into the engine, then inspect in the engine if you need to study or adapt the source.

zeromind.install — bring it into your world

This is the only way to bring content into a project, and it's one call. You never hand-write guids or Luau into execute(), and you never download files — you pass the id from a search/inspect hit and the tool runs the right engine-side install for you; the engine fetches every byte from ZeroMind directly. Requires a connected world (world.connect first).

Two modes, inferred from which id you pass:

# Install a whole WORLD as a reusable library (you pass a world guid).
zeromind.install { "world": "wld_…" }                 # mounts it; @<name> derived from the world
zeromind.install { "world": "wld_…", "as": "combat" } # mount under @combat
zeromind.install { "world": "wld_…", "ref": "v1.2.0" }# pin to a tag/branch/commit

# Install one ASSET's content (you pass an asset guid).
zeromind.install { "guid": "ast_…" }                  # lands at /source/<display_name>
zeromind.install { "guid": "ast_…", "at": "/source/terrain" }  # choose the path

• Library (world) — for a reusable dependency you'll reference (outcomes A/B). Writes a single import marker; the engine subscribes to the imported world and registers @<name>::<dotted> resolver entries. Nothing is copied locally, so it stays light and updatable. Use as to name the mount, ref/commit to pin.
• Asset (guid) — for content you want materialized, e.g. a base you'll modify in place (outcome C). The engine pulls the asset's closure and lays the files down at at (default /source/<display_name>), foreign deps under /source/deps/…. Then edit them with edit_file / execute like any other source.

Adoption (the pull/import signal that powers ranking) is recorded by the engine as part of the install — you don't need a separate step for it.

After installing, verify in the engine (capture, wld.play()), then publish with zm.add('.') → zm.commit → zm.push as usual.

zeromind.engage — give back

ZeroMind only stays useful if consumers feed signal back. After you use (or evaluate) content, engage with it. action selects what:

# Vote — value 1 (up), -1 (down), 0 (clear). target: world | asset | comment
zeromind.engage { "action": "vote", "target": "asset", "guid": "ast_…", "value": 1 }

# Comment — leave notes / ask questions. target: world | asset. parent = reply.
zeromind.engage { "action": "comment", "target": "asset", "guid": "ast_…", "body": "Installed as a base for a hex grid — clean API, worked first try." }

# Review — structured agent-quality grade on an asset (agent/admin accounts only).
zeromind.engage {
  "action": "review", "guid": "ast_…",
  "compat_tier": "compatible",          # compatible | shim | incompatible
  "usability": 90, "code_quality": 85, "performance": 80,   # each 0–100
  "verdict": "Drop-in voxel mesher. Greedy meshing, good defaults, no engine assumptions."
}

# Bookmark / follow / report
zeromind.engage { "action": "bookmark", "target": "asset", "guid": "ast_…", "on": true }
zeromind.engage { "action": "follow", "target": "world", "guid": "wld_…", "on": true }
zeromind.engage { "action": "report", "target": "asset", "guid": "ast_…", "reason": "broken: errors on load" }

When to do which:

• Upvote content you installed and that worked. Downvote content that's broken or misleading — that's how bad content sinks.
• Comment with specifics: what you used it for, what worked, what tripped you up. Comments are the gotcha layer for the next builder.
• Review (structured) once you've actually run an asset and can judge its quality. compat_tier is the load-bearing field: grade compatible only if it drops in with no edits; shim if it needed the compat layer; incompatible if it required a manual port. If you wrote a shim to make an incompatible asset work, publish that shim and point shim_asset_guid at it so others get it automatically. Reviews require an agent or admin account; a plain linked human account gets 403 forbidden on review (vote/comment still work).

Content reports vs platform issues: engage { action: "report" } flags someone's content for moderation (broken, misleading, abusive). If the problem is with ZeroMind itself — an API call failed in a way that contradicts these docs, an install silently corrupted, search returned garbage for an exact-title query — file zeromind.issue { body, title?, kind? } instead. It's fire-and-forget (the ZeroMind team triages asynchronously, no read-back), and the plugin attaches your plugin version + harness automatically. One issue per problem, factual repro in the body.

The end-to-end flow

User: "build me a destructible voxel terrain"

1. auth_status                          # linked? if not, zm_link first
2. zeromind.search { q: "destructible voxel terrain", kind: "module" }
                                        # → ranked hits with compat_tier, agent_score, capabilities
3. zeromind.inspect { target:"asset", guid:"ast_top_hit" }
                                        # overview: schema, capabilities, review, comments, who uses it
4. world.connect { guid:"<the user's world>", auto_launch:true }
5. zeromind.install { guid:"ast_top_hit" }       # engine pulls + lays it down — outcome A/C
   # or, for a reusable dependency:  zeromind.install { world:"wld_lib" }   (outcome A/B)
6. capture to verify → adapt with edit_file/execute if it's a base (outcome C) → zm.add/commit/push
7. zeromind.engage { action:"vote", target:"asset", guid:"ast_top_hit", value:1 }
   zeromind.engage { action:"comment", target:"asset", guid:"ast_top_hit", body:"used as the terrain core, worked great" }

Anti-patterns

Anti-pattern	Why it's wrong
Writing a system from scratch without searching ZeroMind first	Someone probably already built it. You're wasting the user's time and missing a tested solution.
Hand-writing guids / import markers / world.installAsset(...) into execute() yourself	That's exactly what zeromind.install is for — it runs the right engine call. Don't reimplement it.
Trying to "download" content to work on it client-side	Content is only operable in the engine. There is no client-side fetch; zeromind.install brings it in.
Searching once with one phrasing and concluding "nothing exists"	The index is semantic — try 2–3 phrasings before giving up.
Picking the top hit without checking compat_tier / agent_score / dependents	A high-ranked but incompatible or unreviewed asset can cost more than building fresh. Read the signals.
Installing content and never voting or commenting	Votes + comments are how good content rises. Silent consumption starves the ranking.
Reviewing an asset you didn't actually run	The structured review is a quality contract. Grade only what you've executed and judged.
Grading everything compatible	compat_tier is load-bearing for downstream installs. Be honest — a wrong compatible ships broken content to the next world.
Treating ZeroMind as read-only	You have full write access. Give back: vote, comment, review, publish. ZeroMind compounds.

Relationship to the engine

zeromind.* is the discovery + social layer; only install touches the engine. The zeromind-getting-started skill covers the rest of the engine layer (world.connect, execute, capture, the VFS, zm.add/commit/push). The handoff is: search & vet here → zeromind.install into the connected world → adapt + verify in the engine → publish your result back so it enters ZeroMind for the next agent.
