Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00017 | $0.00593 |
| Opus 5 | $0.00009 | $0.00296 |
| Sonnet 5 | $0.00003 | $0.00119 |
| Haiku 4.5 | $0.00002 | $0.00059 |
Grade A, and why
update-codemaps scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Update Codemaps
Analyze the codebase structure and generate token-lean architecture documentation.
Step 1: Scan Project Structure
- Identify the project type (monorepo, single app, library, microservice)
- Find all source directories (src/, lib/, app/, packages/)
- Map entry points (main.ts, index.ts, app.py, main.go, etc.)
Step 2: Generate Codemaps
Create or update codemaps in docs/CODEMAPS/ (or .reports/codemaps/):
| File | Contents |
|---|---|
architecture.md |
High-level system diagram, service boundaries, data flow |
backend.md |
API routes, middleware chain, service → repository mapping |
frontend.md |
Page tree, component hierarchy, state management flow |
data.md |
Database tables, relationships, migration history |
dependencies.md |
External services, third-party integrations, shared libraries |
Codemap Format
Each codemap should be token-lean — optimized for AI context consumption:
# Backend Architecture
## Routes
POST /api/users → UserController.create → UserService.create → UserRepo.insert
GET /api/users/:id → UserController.get → UserService.findById → UserRepo.findById
## Key Files
src/services/user.ts (business logic, 120 lines)
src/repos/user.ts (database access, 80 lines)
## Dependencies
- PostgreSQL (primary data store)
- Redis (session cache, rate limiting)
- Stripe (payment processing)
Step 3: Diff Detection
- If previous codemaps exist, calculate the diff percentage
- If changes > 30%, show the diff and request user approval before overwriting
- If changes <= 30%, update in place
Step 4: Add Metadata
Add a freshness header to each codemap:
<!-- Generated: 2026-02-11 | Files scanned: 142 | Token estimate: ~800 -->
Step 5: Save Analysis Report
Write a summary to .reports/codemap-diff.txt:
- Files added/removed/modified since last scan
- New dependencies detected
- Architecture changes (new routes, new services, etc.)
- Staleness warnings for docs not updated in 90+ days
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

update-codemaps is a command published in the GitHub repository zhmxiaowo/opencode-simple (2 stars, last pushed 5mo ago), licensed MIT. It adds 17 tokens to every session and 593 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
