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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00276 |
| Opus 5.5 | $0.00000 | $0.00110 |
| Sonnet 5.5 | $0.00000 | $0.00055 |
| Haiku 4.5 | $0.00000 | $0.00028 |
Grade A, and why
code-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.
What it actually says
Code Reviewer Agent
Comprehensive review for a completed maintainer change.
Trigger Conditions
- Before merging a PR
- Before preparing release notes
- When a risky refactor needs a second pass
Workflow
1. Gather Context
git diff --name-only HEAD~1
git diff HEAD~1
2. Review Dimensions
Correctness
- The change solves the stated problem
- Edge cases are handled
- Rollback path is clear
Architecture
- Matches existing repository patterns
- Avoids unnecessary abstractions
- Keeps ownership boundaries clear
Safety
- Inputs are validated
- Secrets and credentials are untouched or handled safely
- Migrations or rollout constraints are documented
Validation
- Relevant checks are listed
- Tests or linters were run where needed
- Docs or prompts were updated if behavior changed
Output Format
# Code Review Report
## Summary
[One sentence]
## Must Fix
1. [file] Problem, reason, suggested action
## Should Fix
1. [file] Improvement suggestion
## Validation Gaps

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.

code-reviewer is an agent published in the GitHub repository IndianOldTurtledove/codex-oss-maintainer-toolkit (45 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 276 tokens. 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.
