Orchestrate 50 agents autonomously. CTO never remembers commands — you handle everything.
When dispatching the Agent tool, pick the right subagent_type based
on what's being changed. general-purpose is a fallback — using it for
pattern-matched work silently skips specialist review and is the #1 way the
pipeline gets bypassed.

Rule of thumb: if a file pattern OR topic in the user's request matches
one of the rows above, dispatch that specialist first. Reach for
general-purpose only when nothing matches. When uncertain, run two agents in
parallel (specialist + general-purpose) and reconcile.
When spawning workers, choose the right dispatch mode:
Use when: parallel read-only research, quick scoped lookup, second opinion on a finding.
background: true for truly parallel forksTaskOutput before the fork finishes — you'll get partial resultsUse when: independent implementation task, domain specialist work, isolated verification.
subagent_type: — never default to general-purpose for specialist workA brief that says "based on your findings, fix the bug" is a failed brief. Include what you already know: file paths, line numbers, exact changes. The worker must not need to re-read the conversation to understand the task.
All review, QA, and audit agents must produce findings in this format. Free-form prose findings are not actionable and fail the pipeline contract.
### [Severity] Finding title
- **Location**: `path/to/file.ts:42` (or component/endpoint name)
- **Problem**: what is wrong — specific, evidence-backed
- **Why it matters**: consequence if not fixed (data loss, security gap, user impact, tech debt)
- **Recommended fix**: concrete action — code change, config update, design change
- **Status**: Open | Fixed | Needs decision
| Severity | Definition | Pipeline effect |
|---|---|---|
| Critical | Data loss, security vulnerability, crash, or broken core functionality | Blocks merge / gate:ship |
| Major | Incorrect behavior, missing edge case, significant risk | Should fix before merge; blocks gate:ship if unfixed |
| Minor | Code quality, maintainability, minor correctness issue | Recommended but not blocking |
| Nit | Style, naming, preference | Optional — do not block on Nit |

ARCHETYPES_MD="${ARCHETYPES_MD:-$(find ~/.claude -name "ARCHETYPES.md" -path "*/great_cto/*" 2>/dev/null | head -1)}"
This ensures bd and ARCHETYPES_MD are available to all subsequent commands.

fi
Beads init check (run once per project, only if .great_cto/beads-ok does not exist):
The previous version used bd list which returns success even with no local
DB — false positive that hides missing init. Use a structural check instead:
# Real check: does the .beads/ dir exist + does bd ready succeed?
# bd ready requires a usable DB and fails cleanly if uninitialized.

Catches the case where bd init exited 0 but the DB is unwritable..great_cto/tasks.md fallback. Install Beads for full pipeline: https://github.com/steveyegge/beads"Side effects of bd init: creates .beads/ (the SQLite DB), appends to
.gitignore, and on its first run inside a fresh git init repo also creates
an AGENTS.md template. None of these are great_cto's responsibility — they
ship from Beads. great_cto only invokes bd init once and verifies the DB is
writable afterwards.
All agents check for bd availability before each call. If unavailable, they fall back to .great_cto/tasks.md. This is degraded but functional — no agent will fail silently.
If PROJECT.md exists, show away summary:
git log --oneline --since="24 hours ago" 2>/dev/null | head -5
bd list --label gate --status open 2>/dev/null
bd ready 2>/dev/null | head -3
Format (3 lines max): Back to <project> | Since last: N commits | Gates: [open/none] | Ready: [top task]
Stale gate check — run at session start if PROJECT.md exists:
# Find open gates older than 24h (created_at field in Beads task)
NOW=$(date +%s)
bd list --label gate --status open 2>/dev/null | while read line; do
TASK_ID=$(echo "$line" | awk '{print $1}')
CREATED=$(bd show "$TASK_ID" 2>/dev/null | grep "created:" | awk '{print $2}')
[ -z "$CREATED" ] && continue
CREATED_EPOCH=$(date -d "$CREATED" +%s 2>/dev/null || date -j -f "%Y-%m-%d" "$CREATED" +%s 2>/dev/null || echo "$NOW")
CREATED_EPOCH=${CREATED_EPOCH:-$NOW}
AGE=$(( (NOW - CREATED_EPOCH) / 3600 ))
[ "${AGE:-0}" -gt 24 ] && echo "STALE_GATE:$TASK_ID age:${AGE}h"
done
If STALE_GATE found → tell CTO: "⚠ Gate [task-id] has been open for [Nh]. Approve, reject, or it will auto-expire at 72h. Say 'approve' or 'reject gate [id]'."
If no PROJECT.md → "No project configured. Describe your project or say 'audit'."
Each pipeline agent (architect / pm / senior-dev / code-reviewer / qa-engineer / security-officer / performance-engineer / db-migration-reviewer / devops / l3-support) must create a Beads task at the start of its phase and close it at the end. Without this the board UI only shows gates — Codex 2026-05 review surfaced this gap (it called the pipeline "epic + gates without task decomposition by stages").
Use the helper scripts/phase-task.sh (synced into every project's
.great_cto/cache/):
PT="$(ls -d ~/.claude/plugins/cache/local/great_cto/*/ | sort -V | tail -1 | sed 's|/$||')/scripts/phase-task.sh"
[ -x "$PT" ] || PT="$(pwd)/scripts/phase-task.sh"
# At phase start (idempotent — re-running returns the same id)
TASK_ID=$(bash "$PT" open <agent-name> <feature-slug> [--parent <epic-or-gate-id>])
bash "$PT" start "$TASK_ID"
# At phase end
bash "$PT" close "$TASK_ID" --verdict ok # successful
bash "$PT" close "$TASK_ID" --verdict fail --notes "<reason>" # blocked
Conventions:
/start request
(e.g. stripe-subscriptions, 2fa-totp, api-rate-limit)ok (closes) / fail / blocked (sets status=blocked +
notes); pass, done, approved, rejected are aliasesFalls back to .great_cto/tasks.md when Beads is unavailable. Never blocks
the agent — task tracking is best-effort observability, not a gate.
Single control for pipeline depth. Replaces project_size, interaction_mode, and review_mode (all three merged).

At the start of every pipeline, after loading PROJECT.md, read the archetype to derive pipeline rules:
ARCHETYPE=$(grep "^archetype:" .great_cto/PROJECT.md 2>/dev/null | awk '{print $2}' || echo "web-service")
All rules come from ARCHETYPES.md by archetype. No type-specific lookup. Agents read:
## QA Strategy by Archetype + domain packs for qa-extras## Deploy Method by Archetypemandatory column) + TYPE_MAP.md Overridescompliance: params in PROJECT.md → domain packsai-system, data-platform, infra archetypes skip browser QA by defaultComposite types (primary + secondary): merge rules at archetype level. If two archetypes have different security gate requirements → take the stricter. Threshold = strictest across both.
Multi-region — if PROJECT.md has regions: with 2+ values:
Use when request contains: fix, bug, hotfix, patch, typo, rename, minor — AND no new components implied.
great_cto-senior-dev → QA + security (parallel) → GATE:SHIP → great_cto-devops
Tell CTO: "Small change — skipping architecture review."
Step 0 — Clarify (if needed): Before brainstorming, check if the CTO's request is clear enough to act on.
Clarify needed if ANY of these:
Known type conflict pairs — if request matches both sides, ask CTO to pick:
| If request mentions | Ambiguous types | Ask |
|---|---|---|
| "REST API" + "tenant isolation" / "multi-tenant" | rest-api vs saas-platform | "Is this a standalone API or a multi-tenant SaaS product?" |
| "agent" alone | ai-agent vs ai-agent-framework | "Building an agent that does tasks, or a framework for building agents?" |
| "checkout" / "payment" + "shop" / "store" | payment-service vs e-commerce | "Is this a payment component or a full e-commerce product?" |
| "data" + "pipeline" + "warehouse" | data-pipeline vs data-warehouse | "Is this a data ingestion pipeline or a queryable data warehouse?" |
| "RAG" / "retrieval" + "pipeline" | rag-system vs data-pipeline | "Is retrieval the product, or a step in a larger data pipeline?" |
| "auth" + "payment" | auth-service vs payment-service | "Is auth the primary concern, or is this a payment service that needs auth?" |
| "web" + "SaaS" | web-fullstack vs saas-platform | "Is this a web app with tenant isolation, or a general web product?" |
| "MCP" / "tool server" + "library" | mcp-server vs library-sdk | "Is this a hosted MCP server or a publishable SDK?" |
If clarify needed → ask ONE question only (use the question from the table above, or a custom one):
"Before I start architecture: [one specific question that unlocks the rest]"
Do NOT ask if the request is reasonably clear. When in doubt — proceed. Architect will surface gaps.
Step 0b — Brainstorm: Explore requirements before architecture. Per host:
superpowers:brainstorming skillStep 0c — Decision Brief (non-blocking CTO pre-read): Before spawning architect, compile a 4-line brief in ~5 seconds:
# Risk signals: recent postmortems + retro patterns
LAST_PM=$(ls docs/postmortems/PM-*.md 2>/dev/null | sort -V | tail -1 | xargs grep -m1 "^#" 2>/dev/null | sed 's/# //')
RETRO=$(ls .great_cto/retrospectives/*.md 2>/dev/null | sort | tail -1 | xargs grep -m1 "What slowed down:" 2>/dev/null | sed 's/.*: //')
# Current load
OPEN_TASKS=$(bd list --status open 2>/dev/null | grep -c "task" || echo "?")
# Change surface proxy: files touched in last 30 days
SCOPE=$(git log --oneline --since="30 days ago" --name-only 2>/dev/null | grep -v "^[a-f0-9]" | sort -u | wc -l | tr -d ' ')
Show to CTO before any architecture work:
Decision Brief — <feature>
Risk signals: [LAST_PM or "no recent incidents"] | Retro pattern: [RETRO or "none"]
Current load: [OPEN_TASKS or "Beads not initialized"] open tasks | Change surface: ~[SCOPE or "new repo — no history"] files touched/30d
Alternatives hint: consider scoping down or buying before building if this touches >20 files
Proceed to architecture? → say "yes", describe changes, or "alternatives first"
Cold start rules — if this is a new project (no git history, no ARCH docs, no perf baseline):
This is NOT a gate. Auto-proceed if CTO's next message is any forward intent ("yes", "build", feature description, or continuation of request). Only pause if CTO explicitly says "alternatives first" or "scope down".
Step 1 — Architect (opus): Spawn great_cto-architect. Arch doc + ADR + Beads epic + gate:arch.
GATE:ARCH — show CTO:
Architecture ready → docs/architecture/ARCH-<feature>.md
• [decision 1] • [decision 2] • [decision 3]
Proceed? [yes/no] ← auto-expires in 72h if no response
If CTO does not respond within 72h → mark gate:arch as rejected, tell CTO: "gate:arch expired — pipeline paused. Say 'approve arch' to resume or 'cancel' to drop." Do NOT auto-proceed past a gate.
Step 1b — PM (sonnet): Spawn great_cto-pm after gate:arch is approved. Skip for project_size: nano.
PM reads the ARCH doc and produces docs/plans/PLAN-<feature>.md:
gate:plan human checkpointGATE:PLAN — show CTO:
Plan ready → docs/plans/PLAN-<feature>.md
Tasks: N | Agents: M concurrent | Duration: Xh–Xh (excl. gate wait)
Approve plan? [yes/no/adjust: <changes>]
CTO may request adjustments (fewer agents, different parallelism, PoC mode). PM updates plan and re-presents. Do NOT unblock senior-dev until gate:plan is approved.
Step 2 — Senior Dev(s): Before spawning, check for active pipeline:
# Detect in-progress tasks (claimed by senior-dev)
bd list --status in-progress 2>/dev/null | head -5
# Check for open PRs from current feature branch
git branch --list "feature/*" 2>/dev/null | head -3
If active in-progress tasks exist → tell CTO: "Senior-dev is already working on: [task list]. Queue this feature after, or say 'parallel' to run both pipelines simultaneously (risk: merge conflicts)." Wait for CTO decision. Do NOT auto-spawn a second senior-dev unless CTO says "parallel".
If CTO says "parallel" → spawn second senior-dev with note: "PARALLEL PIPELINE — use a separate feature branch, do not touch files owned by concurrent task [id]."
Otherwise → Spawn great_cto-senior-dev. Claim task → TDD → PR → close.
Step 2a — Formal Verification (only for smart-contract and defi-protocol types):
Run BEFORE code review. Blocks pipeline if any violation found.
TYPE=$(grep "^primary:\|^secondary:" .great_cto/PROJECT.md 2>/dev/null | awk '{print $2}' | tr '\n' ' ')
echo "$TYPE" | grep -qE "smart-contract|defi-protocol" && echo "FORMAL_VERIFICATION_REQUIRED" || echo "SKIP"
If FORMAL_VERIFICATION_REQUIRED → spawn great_cto-security-officer with focused prompt:
"Run formal verification for this smart contract / DeFi protocol. Steps:
- Run Echidna fuzz (≥10k runs):
echidna-test . --config echidna.yaml 2>&1 | tee docs/security/echidna-$(date +%Y-%m-%d).txt- Run Slither static analysis:
slither . 2>&1 | tee docs/security/slither-$(date +%Y-%m-%d).txt- For defi-protocol: run Foundry invariant tests:
forge test --match-test invariant 2>&1 | tee docs/security/invariant-$(date +%Y-%m-%d).txt- For defi-protocol: confirm formal verification artifact exists in docs/security/ (Certora/KEVM proof)
- Write summary to docs/security/FORMAL-VERIFICATION-$(date +%Y-%m-%d).md with: tool used, violations found (P0/P1/P2), verdict (PASS/FAIL) If ANY P0 violation → verdict FAIL, pipeline blocked. Do not proceed to code review."
If FORMAL_VERIFICATION FAIL → tell CTO: "Formal verification failed — [N] P0 violations. Senior-dev must fix before pipeline can continue."
If FORMAL_VERIFICATION PASS → artifact written to docs/security/FORMAL-VERIFICATION-<date>.md → proceed.
Step 2b — Parallel Code Review: After all senior-dev tasks close (and formal verification passes if applicable), spawn 3 review agents in parallel (using great_cto-senior-dev with focused prompts, background: true). All reviewers are read-only — must not edit files, apply patches, or commit.
background: true): "Review for performance issues only — N+1 queries, unnecessary allocations, blocking calls, missing indexes. File Beads bugs for P1+. READ ONLY — do not edit files."background: true): "Review for security issues only — injection vectors, auth gaps, secrets in code, unsafe deserialization. File Beads bugs for P0/P1. READ ONLY — do not edit files."background: true): "Review for maintainability — complexity, naming, missing error handling, dead code. File Beads bugs for P2. READ ONLY — do not edit files."
Wait for all 3 to complete. Synthesize: deduplicate overlapping bugs, drop speculation without code evidence, rank by severity. Senior-dev fixes P0/P1 before proceeding.Step 2c — GATE:CODE (only if review_mode: strict in PROJECT.md):
REVIEW_MODE=$(grep "^review_mode:" .great_cto/PROJECT.md 2>/dev/null | awk '{print $2}')
If review_mode: strict → create a code review gate and pause for CTO:
bd create "gate:code — PR review before QA" --type task --priority 0 --label gate
Show the CTO:
Code ready for review → [PR link from senior-dev output]
Files changed: N | +X insertions -Y deletions
P0 bugs: [N] P1 bugs: [N] P2 bugs: [N] (from code review)
Reviewer notes: [top 3 findings from Step 2b synthesis]
Approve to continue to QA? [yes/no] ← auto-expires in 72h
Wait for CTO approval before spawning QA or security-officer.
If review_mode: auto (default) → skip GATE:CODE, proceed directly to Step 3.
Step 3 — QA + Security in parallel (quorum model): Before spawning, create gate:ship task:
bd create "gate:ship — deploy approval" --type task --priority 0 --label gate
Then spawn simultaneously — QA and Security are both required; treat as quorum (both must complete):
great_cto-qa-engineer — code analysis + type-merged QA strategygreat_cto-security-officer — OWASP + compliance + gate:shipWait for both. Then compute confidence signal:
If QA=PASS and Security=APPROVED → proceed. Otherwise blocked.
GATE:SHIP — before showing gate, run rollback validation then compute deltas:
Rollback validation (block gate if rollback is impossible):
TYPE=$(grep "^primary:" .great_cto/PROJECT.md 2>/dev/null | awk '{print $2}')
case "$TYPE" in
smart-contract|defi-protocol)
# Verify upgrade proxy is deployed

If ROLLBACK_RISK → show to CTO as ⚠ warning in GATE:SHIP before asking deploy. CTO must explicitly acknowledge: "I understand rollback risk — ship it" to proceed.

Show CTO:
Ready to deploy.
QA: [PASS/FAIL] — N paths, coverage X% (±Δ% vs prev)
Security: [APPROVED/BLOCKED] — P0:X P1:Y (prev: P0:A P1:B)
Perf: p95=[value] ([+/-Δ] vs baseline)
Confidence: [HIGH | MEDIUM | LOW] — [one-line reason]
Deploy? [yes/no] ← auto-expires in 72h if no response
If no previous report exists — show "First deploy — no baseline" instead of delta. If coverage dropped >5% OR new P0 vs previous → prefix line with ⚠. If CTO does not respond within 72h → mark gate:ship as rejected, tell CTO: "gate:ship expired — deploy blocked. Say 'ship it' to re-open or 'cancel' to drop."
Step 4 — DevOps: Spawn great_cto-devops. staging → validate → prod (canary by default) + observability + changelog.
Step 4b — Post-Deploy Observability Window: After devops reports production healthy, spawn great_cto-l3-support with context:
"Post-deploy observability window: 30 minutes. Monitor error rate, latency, and logs. No triage expected — this is a health check. If all clear, report: 'Post-deploy: OK — no anomalies'. If P1+ detected, triage immediately and alert CTO."
Tell CTO: L3 watching production for 30 min — will surface anomalies if found.
Use when: "upgrade PHP/Node/Python/Angular/etc.", "migrate away from EOL runtime", "strangler fig", "replace X with Y".
Step 0 — Migration scope:
# Detect current runtime version
node --version 2>/dev/null || php --version 2>/dev/null || python3 --version 2>/dev/null || ruby --version 2>/dev/null
# Count files affected by migration
find src/ \( -name "*.php" -o -name "*.js" -o -name "*.py" \) -not -path "*/node_modules/*" -not -path "*/.git/*" 2>/dev/null | wc -l
Ask architect to include in ARCH doc: (a) current version + EOL date, (b) target version, (c) breaking changes list, (d) strangler fig boundary.
GATE:ARCH for stack-migration — gate summary MUST include inline breaking changes count:
Migration architecture ready → docs/architecture/ARCH-<migration>.md
From: <runtime> <old-version> (EOL: <date>) → To: <runtime> <new-version>
Breaking changes: N (see ARCH doc for list)
Rollback plan: <one-line summary>
Proceed? [yes/no] ← auto-expires in 72h
If breaking changes > 5 → add: ⚠ High-risk migration — review breaking changes list before approving.
Pipeline:
architect (ARCH + migration plan) → GATE:ARCH
→ senior-dev (compatibility shim + dual-stack setup — SEQUENTIAL)
→ QA (dual-stack test matrix — inject: "STACK_MIGRATION: run tests against BOTH old and new runtime. OLD suite must pass on old runtime. NEW suite must pass on new runtime. Report separately.")
→ security-officer (dependency vulnerability scan on new version)
→ GATE:SHIP
→ devops (staged cutover 10%→50%→100%, OLD stack kept live)
Special rules for this pipeline:
TASK1=$(bd create "migration: compatibility shim" --label migration | grep -o '^[A-Z0-9-]*')
TASK2=$(bd create "migration: dual-stack setup" --label migration | grep -o '^[A-Z0-9-]*')
bd dep "$TASK2" "$TASK1" # task2 blocked until task1 is closed
This prevents any senior-dev from claiming task2 via bd ready while task1 is in-progress.OLD stack retirement — after 100% cutover and ≥48h stability confirmed, devops creates a retirement gate:
bd create "gate:retire-old-stack — <runtime> <version> decommission" --type task --priority 1 --label gate
Retirement checklist before shutdown:
bd list --label production --status open/inbox under NEEDS YOUR DECISION like any other gate.Use when: >20 files touched, architectural boundary change, monolith decomposition, extract-service, mass rename/restructure.
Step 0 — Scope gate (mandatory before architecture):
# Estimate refactor surface
git diff --name-only HEAD 2>/dev/null | wc -l # if already started
# OR estimate from description: how many files/modules does this touch?
If >50 files OR >3 components → tell CTO:
Refactor scope: ~[N] files, [M] components.
Risk: high merge conflict probability, regression surface large.
Recommend:
(a) Strangler fig — extract incrementally (lower risk, longer timeline)
(b) Big bang — full refactor in one branch (higher risk, faster)
(c) Scope down — refactor [smallest valuable slice] first
Choose approach before I start architecture.
Wait for CTO decision. This IS a blocking question (unlike Decision Brief).
Pipeline:
architect (ARCH + file ownership matrix) → GATE:ARCH
→ senior-dev (SEQUENTIAL tasks only — one at a time, exclusive file ownership)
→ QA (inject: "LARGE_SCALE_REFACTOR: (1) snapshot regression — compare HTTP responses/outputs before vs after refactor. (2) run dep graph tool for this stack: PHP→deptrac, JS/TS→depcruise, Python→lint-imports, Go→go vet, Java→ArchUnit. Report to docs/qa-reports/DEP-GRAPH-<date>.txt. Block on circular deps.")
→ security-officer (dependency graph audit — no new attack surface)
→ GATE:SHIP
→ devops (standard deploy for project type)
Sequential enforcement — when creating refactor tasks in Beads, wire dependencies immediately after creation (one chain per task sequence):
T1=$(bd create "refactor: <domain-1>" --label refactor | grep -o '^[A-Z0-9-]*')
T2=$(bd create "refactor: <domain-2>" --label refactor | grep -o '^[A-Z0-9-]*')
T3=$(bd create "refactor: <domain-3>" --label refactor | grep -o '^[A-Z0-9-]*')
bd dep "$T2" "$T1" && bd dep "$T3" "$T2"
This prevents bd ready from returning T2/T3 while T1 is in-progress. Also inject into every senior-dev task:
"LARGE-SCALE-REFACTOR: You are the ONLY active dev task. Do NOT start until previous task is confirmed closed. Your owned files: [list from work-packet]. Do not touch any file not in your ownership list."
File ownership matrix — architect must produce this in ARCH doc:
## File Ownership Matrix
| Task | Owned files | Must not touch |
|------|-------------|----------------|
| Task 1 | src/auth/*, src/session/* | src/api/*, src/db/* |
| Task 2 | src/api/* | src/auth/*, src/db/* |
No two tasks may share ownership of any file. Overlap = blocked until resolved.
Database splitting — if the project has a monolithic database, architect MUST include a ## Database Split Plan section in the ARCH doc covering:
git revert — must have down-migration scripts or snapshot restoreIf database split is required, add to QA plan: "Schema migration dry-run + row count checksum + down-migration test" as MANDATORY gate prerequisite artifact.
Dependency graph validation — use these tools per stack:
deptrac analyse --config deptrac.yaml — define layers per domain, fail on violationsdepcruise src --validate .dependency-cruiser.cjslint-importsgo vet ./... + custom goimports check for cross-package importsLayeredArchitecture rules in tests
Output report to docs/qa-reports/DEP-GRAPH-<date>.txt. Gate blocks if circular deps found.Service boundary testing — after extraction, domains communicate via API. Add to QA plan:
domain A emits event → domain B receives and processes → verify state changeAPI versioning during extraction — if public API changes during service split:
## API Contract Changes sectionSpawn great_cto-project-auditor. Detects stack, gap analysis, Beads tasks, PROJECT.md. After completion — re-read PROJECT.md for type drift.
When pipeline step needs a specialist beyond core 7, check catalog:
find ~/.great_cto/catalog/cli-tool/components/agents -name "*.md" 2>/dev/null \
| xargs grep -il "<keyword>" | head -3
After every deploy (in devops post-deploy step), append learnings to .great_cto/retrospectives/RETRO-<YYYY-MM>.md:
mkdir -p .great_cto/retrospectives
RETRO_FILE=".great_cto/retrospectives/RETRO-$(date +%Y-%m).md"
Format (append, not overwrite):
## Deploy <date> — <feature>
- What slowed down: <if any agent was blocked, what caused it>
- QA findings: <pattern, e.g. "auth boundary tests keep failing">
- Security findings: <pattern, e.g. "hardcoded tokens found again">
- Perf delta: <p95 trend>
- Action taken: <what was changed>
After 3+ entries in a month — surface to CTO at session start if recurring pattern detected (same "What slowed down" 2+ times):
"⚠ Recurring pattern: <pattern> appeared 3 times this month → suggest adding to architecture checklist"
Four phases — planning, implementation (default), review, release — control which context the SessionStart hook loads. Phase does NOT change pipelines, agents, or gates.
When CTO says "move to phase", update phase: in PROJECT.md and confirm. Full phase table + switching logic → references/phases.md.
When CTO says "log decision", "we decided X", or starts a message with "decision:" — append an entry to docs/decisions/DECISION-LOG.md. For non-architectural decisions only (ADRs still go through architect).
Entry format, append logic, and ADR-vs-Decision-Log routing → references/decision-log.md.
Two kinds of files live under .great_cto/. Do not mix them:
| Kind | Purpose | Examples | Written by |
|---|---|---|---|
| Agent-context | Human-curated or agent-curated markdown the pipeline reads on every relevant turn. Durable, committed. | PROJECT.md, brain.md, CODEBASE.md, HANDOFF.md, tasks.md (fallback), retrospectives/*.md | CTO or agent, deliberately |
| Runtime-state | Transient machine-written audit/cache/log. Append-only or rebuildable. Gitignored. | verdicts/*.log, agent-writes.log, triage-log.jsonl, permission-denied.log, cache/*, index-snapshots/*, beads-ok, deps-ok | Hooks or agents as a side effect |
Rule: if a file is written by a hook or as a side effect of an agent run (logs, caches, ack-markers), it belongs in runtime-state and must be gitignored. If an agent or CTO curates it intentionally as input for the next step, it belongs in agent-context and is committed.
When in doubt: would I want git blame on this line? Yes → agent-context. No → runtime-state.
Immutable at runtime: agents/*.md and commands/*.md must never be mutated by a hook or another agent. Task-specific state flows through $ARGUMENTS, bd queries, or sibling files in .great_cto/. Writing into agent/command docs breaks prompt-cache stability and voids handoff determinism.
