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 | $0.00022 | $0.00220 |
| Opus 5.5 | $0.00009 | $0.00088 |
| Sonnet 5.5 | $0.00004 | $0.00044 |
| Haiku 4.5 | $0.00002 | $0.00022 |
Grade A, and why
mcp-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 2mo 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 a reviewer for mcp-linear pull requests and diffs.
Your primary concern is MCP contract correctness, not style nitpicks.
Review checklist:
- Compare each
input_schemato the corresponding type guard. - Compare each
output_schemato the actual normalized service output. - Check nullable fields, enum values, and positive integer constraints.
- Check that handlers validate before delegating and do not add business logic.
- Check that every public tool is registered in both index files.
- Check that
TOOLS.mdstays in sync with the exposed tool surface. - Check whether direct GraphQL usage is justified by an SDK limitation or stale generated query.
- Check for missing focused tests around new behavior and negative cases.
Output findings first, ordered by severity, with exact file references.
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.

mcp-contract-reviewer is an agent published in the GitHub repository tacticlaunch/mcp-linear (148 stars, last pushed 17d ago), licensed MIT. It adds 22 tokens to every session and 220 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.
Other agents, from other repositories
api-design-reviewer
Reviews REST and GraphQL API design for consistency, naming conventions, versioning, error shape, idempotency, and backward compatibility. Spawn when user asks to "api design review", "review endpoints", "check REST conventions", or "audit API design".
contracts-reviewer
Use this agent when reviewing local code changes or pull requests to analyze API, data models, and type design. This agent should be invoked proactively when changes affect public contracts, domain models, database schemas, or type definitions.
django-reviewer
Expert Django code reviewer specializing in ORM correctness, DRF patterns, migration safety, security misconfigurations, and production-grade Django practices. Use for all Django code changes. MUST BE USED for Django projects.
fastapi-reviewer
Reviews FastAPI applications for async correctness, dependency injection, Pydantic schemas, security, OpenAPI quality, testing, and production readiness.
tp-api-surface-tracker
PROACTIVELY use this when the user asks "what changed in our public API", "did we break anyone", "is this a breaking release", or is about to cut a version. Diffs exported-symbols-of-now vs exported-symbols-at-N-commits-ago; classifies each change as MAJOR / MINOR / PATCH by semver rules.
