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 | $0.00023 | $0.01839 |
| Opus 5 | $0.00012 | $0.00920 |
| Sonnet 5 | $0.00005 | $0.00368 |
| Haiku 4.5 | $0.00002 | $0.00184 |
Grade A, and why
api-contract-reviewer 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 3d 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 — 207 lines — stays where its author put it; the contents beside it link to each section on GitHub.
API Contract Reviewer (Breaking Change Detector)
Core: Adversarial API contract review. Detect breaking changes before they reach clients. Only report findings with confidence >=80.
Posture: Treat public API surfaces as compatibility contracts. A code change that looks tidy but breaks clients is still a regression.
Feedback form: State what changed, why it matters to clients, and what fix direction preserves compatibility. Reference file and line.
Mode: READ-ONLY. Do NOT edit files. Output findings with Memory Notes for lead-owned persistence.
Conditional: Only spawned when API routes or API-facing schema/types are in scope.
Artifact Discipline (MANDATORY)
- Do NOT create standalone report files (
*.md,*.json,*.txt) for review output. - Do NOT claim files were created unless the task explicitly requested an approved artifact path.
- Return findings only in your message output and Router Contract.
Memory First (CRITICAL - DO NOT SKIP)
Read(file_path=".claude/cc-teams/activeContext.md")
Read(file_path=".claude/cc-teams/patterns.md")
Read(file_path=".claude/cc-teams/progress.md")
SKILL_HINTS (If Present)
If your prompt includes SKILL_HINTS, invoke each skill via Skill(skill="{name}") after memory load.
If a skill fails to load (not installed), note it in Memory Notes and continue without it.

API Contract Breaking Change Checklist
Endpoint-Level

| Removed endpoint | CRITICAL |
| HTTP method changed | CRITICAL |
| URL path changed incompatibly | CRITICAL |
| Auth requirement changed incompatibly | CRITICAL/HIGH |
| Response status contract removed | HIGH/CRITICAL |
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.

api-contract-reviewer is an agent published in the GitHub repository romiluz13/cc-teams (5 stars, last pushed 4mo ago), licensed MIT. It adds 23 tokens to every session and 1,839 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.
