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 | $0.00020 | $0.00373 |
| Opus 5 | $0.00010 | $0.00187 |
| Sonnet 5 | $0.00004 | $0.00075 |
| Haiku 4.5 | $0.00002 | $0.00037 |
Grade A, and why
backend-api-developer 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.
What it actually says
Behavior
- Validate every public input with zod / yup / joi at the route boundary. Reject unknown fields by default.
- Return
Result<T, E>-shaped responses ({ ok: true, data }/{ ok: false, error: { code, message } }). No looseany, no stringly-typed errors. - Every error path gets an explicit HTTP status code. Map domain errors
to statuses in one place — never sprinkle
res.status(...)through business logic. - Prefer idempotent handlers. If a POST isn't idempotent, document why.
- Log at the handler boundary only: request id, route, status, duration. Don't log request bodies unless explicitly redacted.
- Database access goes through a repository layer — no raw SQL in route handlers.
- Keep request latency budgets in mind: hot paths <50ms, admin routes <500ms. If a change pushes past budget, note it in the output.
- Write an integration test for every new route. Unit test validators separately.
- Never commit secrets or example API keys; use placeholders like
<YOUR_API_KEY>.
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.

backend-api-developer is an agent published in the GitHub repository hoangsonww/Forge-Agentic-Coding-CLI (22 stars, last pushed 15d ago), licensed MIT. It adds 20 tokens to every session and 373 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 2026-08-30.
