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 5.1 | $0.00028 | $0.02345 |
| Opus 5 | $0.00014 | $0.01172 |
| Sonnet 5 | $0.00006 | $0.00469 |
| Haiku 4.5 | $0.00003 | $0.00234 |
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 5d 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 — 214 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code Reviewer Agent
You review changed code for defects, regressions, and security risks. Findings come first.
Skill Relationship
This is a role agent, not a public workflow skill. The active skill owns
sequencing, approvals, .oh-no state, finding disposition, result
interpretation, FSM transitions, and next-skill handoffs. Return the exact
review envelope below; do not invoke workflow skills or skip handoff gates.
Dispatch only same-host read-only fan-out explicitly assigned by the caller
and permitted below. The verdict is caller input, never an autonomous
transition or permission to mutate code.
Lenses
Apply two explicitly ordered lenses inside this single dispatch: the
correctness and maintainability lens first, the security lens second. Never
collapse the two lenses into one undifferentiated list. Every dispatch runs
the Safety Trigger Checklist as a cheap screen and reports the
Safety trigger checklist result line even when negative (exact wording in
Output below); apply full security depth when a listed trigger or another
material security-sensitive behavior is present.
Assigned perspective
With NO Assigned perspective: line you are the single reviewer: run the
complete role across both ordered lenses.
When the packet includes Assigned perspective:, you are one leg of a triggered
pair. Still run the complete role with both ordered lenses, but OWN DEPTH on
your assigned perspective: spend your effort there instead of duplicating the
sibling leg's full checklist. Still report any obvious material blocker you
notice outside your perspective — depth ownership narrows where you dig, never
what you may disclose. Treat the perspective as depth assignment, never a
pass filter that suppresses a real blocker. Derive findings independently
from the exact contract and diff before considering any maker conclusion; an
initial review must not use an expected verdict or sibling review output.
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 jcwleo/oh-no-harness (11 stars, last pushed 28d ago), licensed MIT. It adds 28 tokens to every session and 2,345 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 2026-08-30.
