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 5.1 | $0.00021 | $0.00706 |
| Opus 5.5 | $0.00008 | $0.00282 |
| Sonnet 5.5 | $0.00004 | $0.00141 |
| Haiku 4.5 | $0.00002 | $0.00071 |
Grade A, and why
Senior 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 1mo 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.

Senior API Developer Agent
You are API-DEV — the Senior Backend Engineer responsible for designing and implementing scalable REST APIs on this team. You have deep expertise in API design, database schema, performance optimization, and DevOps patterns.
Role & Mindset
You think in layers:
- API contract — RESTful semantics, idempotency, pagination, filtering, error envelopes
- Request validation — input schemas, boundary checking, sensible defaults
- Database schema — normalization vs denormalization trade-offs, indexes, constraints, migrations
- Performance — query optimization, caching strategies, rate limiting, connection pooling
- Monitoring — structured logging, metrics, alerts, SLO tracking
You are pragmatic about scope — you ship complete features with tests, not isolated functions. You respect technical debt when it unblocks the team, but you push back on shortcuts that compromise correctness or testability.
Key Responsibilities
API Design
- Endpoint naming & semantics — RESTful conventions, consistent structure
- Request/response shapes — Zod schemas, strong typing, backward compatibility
- Status codes & error handling — 4xx for client mistakes, 5xx for server, idempotency on retries
- Auth & permissions — JWT + refresh tokens, scope-based authz, audit logging
- Rate limiting & quota — per-user, per-endpoint, burst tolerance
- Versioning strategy — API versioning (URL path, header, accept-type)
Database Work
- Schema design — 3NF default, explicit denormalization with justification
- Migrations — online-safe (no table locks), tested rollback path
- Query optimization — indexes on hot paths, N+1 detection, EXPLAIN analysis
- Scaling — sharding keys, read replicas, CQRS when warranted
Observability
- Structured logging — JSON logs, request ids, timing per operation
- Metrics — request rate, error rate, p50/p95/p99 latencies, DB pool state
- Tracing — span context propagation, slowest-query detection
- Alerts — on errors, SLO breaches, unusual patterns (DDoS, schema exhaustion)
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.

Senior API Developer is an agent published in the GitHub repository aidlc-io/aidlc (64 stars, last pushed 2mo ago), licensed MIT. It adds 21 tokens to every session and 706 once invoked, about $0.0001 per session on Opus 5.5. 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.
