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 | $0.00014 | $0.01182 |
| Opus 5 | $0.00007 | $0.00591 |
| Sonnet 5 | $0.00003 | $0.00236 |
| Haiku 4.5 | $0.00001 | $0.00118 |
Grade A, and why
api-gen 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 4d ago.
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.
How it starts
The opening of the file, as written. The whole thing — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Generate production-quality REST API endpoints from a description provided in $ARGUMENTS.
Step 1 — Understand the Requirements
Parse $ARGUMENTS to determine:
- Resource name (e.g., "users", "products", "orders")
- Operations needed (CRUD by default, or specific operations if stated)
- Fields and types (if specified, otherwise infer reasonable defaults)
- Relationships to other resources (if mentioned)
- Authentication requirements (if mentioned)
If $ARGUMENTS is vague (e.g., just "users"), generate a standard CRUD API with sensible defaults and ask the user to confirm the field list before writing code.
Step 2 — Detect the Project's Stack
Search the project to determine:
- Framework: Express, Fastify, Koa, NestJS, Django REST Framework, Flask, FastAPI, Gin, Echo, etc.
- Language: TypeScript, JavaScript, Python, Go, etc.
- Database/ORM: Prisma, TypeORM, Sequelize, SQLAlchemy, Django ORM, GORM, etc.
- Validation library: Zod, Joi, class-validator, Pydantic, marshmallow, etc.
- Project structure: Where do routes, controllers, models, and tests live?
- Existing patterns: Read 1-2 existing route files to match the project's conventions exactly.
If no existing backend framework is found, ask the user which stack to use. Do not assume.
Step 3 — Design the API
Create a specification before writing any code:
## API Design: [Resource]
Base path: /api/[resource]
| Method | Path | Description | Auth | Status Codes |
|--------|-----------------|----------------------|------|--------------------|
| GET | / | List all (paginated) | Yes | 200, 401 |
| GET | /:id | Get one by ID | Yes | 200, 401, 404 |
| POST | / | Create new | Yes | 201, 400, 401, 409 |
| PUT | /:id | Update by ID | Yes | 200, 400, 401, 404 |
| DELETE | /:id | Delete by ID | Yes | 204, 401, 404 |

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.
- 4d ago First seen · 142 lines · 14 tokens per session scan A 270827cedfc6
api-gen is a command published in the GitHub repository halflength-ampleness75/claude-code-recipes (2 stars, last pushed 5d ago), licensed MIT. It adds 14 tokens to every session and 1,182 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.

coograph-verify
Verify that the described work is complete and correct. Provide evidence for every claim. You verify — you do not implement or fix style.
prune
Trim transcript clutter to extend session lifetime — analyze, prune a copy, or toggle the after-each-turn service. Dry-run by default; gains land at resume/compaction, not the current turn.
add-dep
Vet a new or changed third-party dependency for license, provenance, and supply-chain risk before any install runs.
conflict
Stop everything and surface a rule conflict — persona vs. docs vs. code. Present both sides and the conflict-hierarchy level; the user resolves. No silent reconciliation.
status
Show the project's current state at a glance — stage, open tasks, open questions, overrides since the last checkpoint, current branch. Read-only.
commit
Run the full commit gate — the only sanctioned path to a git commit.
