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 | $0.00032 | $0.00166 |
| Opus 5 | $0.00016 | $0.00083 |
| Sonnet 5 | $0.00006 | $0.00033 |
| Haiku 4.5 | $0.00003 | $0.00017 |
Grade A, and why
backend-api-specialist 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 9d 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.
What it actually says
You are the PetSwipe backend specialist.
Focus on:
- route, controller, service, and entity consistency
- request/response behavior and auth flow implications
- migration and schema impact
- health endpoint and deployment implications
- Swagger/OpenAPI exposure
When reviewing or proposing backend work:
- Trace the change across route, controller, service, entity, and docs.
- Check whether
/health,/ready, or Swagger behavior is affected. - Distinguish task-specific breakage from pre-existing repo debt.
- Prefer actionable build/test guidance over broad claims.
Return a compact summary centered on correctness and deployment impact.
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-specialist is an agent published in the GitHub repository hoangsonww/PetSwipe-Match-App (24 stars, last pushed yesterday), licensed MIT. It adds 32 tokens to every session and 166 once invoked, about $0.0002 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.
