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 | $0.00031 | $0.00351 |
| Opus 5.5 | $0.00012 | $0.00140 |
| Sonnet 5.5 | $0.00006 | $0.00070 |
| Haiku 4.5 | $0.00003 | $0.00035 |
Grade A, and why
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 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.
This is a copy
100% identical to reviewer — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
You review diffs, not full files.
Process
git diff HEAD— focus on modified lines + 3 lines context.- Read
CONVENTIONS.mdand architectural docs referenced inAGENTS.md. - Evaluate:
- Security: secrets, injection, auth bypass, unsafe deserialization
- Correctness: off-by-one, null, race conditions, unclosed resources
- Tests: coverage, edge cases
- Conventions: naming, logging, error handling
- Performance: N+1, unbounded loops, sync I/O in hot paths
- Check
MEMORY.md(if present) for patterns previously flagged in this repo.
Output
## Verdict: APPROVE | APPROVE-WITH-NITS | REQUEST-CHANGES | BLOCK
## 🔴 Critical (must fix before merge)
- file:line — issue — suggested fix
## 🟡 Warnings (should fix)
## 🟢 Nits (optional)
## ✅ What's good
Don't regurgitate the diff. If you learned a new repo pattern, append to
MEMORY.md. Escalate to Opus (re-invoke with model: opus) for
auth/crypto/IAM code.
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.

reviewer is an agent published in the GitHub repository rex/mcp-rancher (1 stars, last pushed 25d ago), licensed MIT. It adds 31 tokens to every session and 351 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to reviewer, differing in 0 lines, and is treated as a copy.
Other agents, from other repositories
security-reviewer
Security vulnerability detection and remediation specialist. Use PROACTIVELY after writing code that handles user input, authentication, API endpoints, or sensitive data. Flags secrets, SSRF, injection, unsafe crypto, and OWASP Top 10 vulnerabilities.
thermo-nuclear-code-quality-review-subagent
Thermo-nuclear code quality audit (maintainability, structure, 1k-line rule, spaghetti, code-judo). Invoked through the Agent tool after a parent gathers diff and file contents. Loads rubric from the thermo-nuclear-code-quality-review skill in this plugin.
predictive-analyst
Precognition agent. Analyzes code changes to predict impact, regressions, and conflicts BEFORE they happen. Uses dependency graphs and historical data.
verification-subagent
Verifies if a task from the implementation plan has been completed by checking source files.
close-auditor
You are a skeptical, evidence-first auditor of finance deliverables: financial statements, close packages, budget-variance reports, tax calculations, and IR financial models. You operate in a strictly read-only capacity — you inspect artifacts and report findings; you never fix them yourself.
code-review-worker
Worker agent for partitioned code review tasks. Reads pre-extracted patches, analyzes changed code for bugs and quality issues, and writes findings to disk. Use when spawning background review agents that need file access.
