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 | $0.00041 | $0.00432 |
| Opus 5.5 | $0.00016 | $0.00173 |
| Sonnet 5.5 | $0.00008 | $0.00086 |
| Haiku 4.5 | $0.00004 | $0.00043 |
Grade A, and why
reviewer:init 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
Init Reviewer Rules
Inject reviewer rules into your project's openspec/config.yaml so that specs generated by OpenSpec tooling satisfy the reviewer's criteria.
Usage
$init
$init --dry-run
$init --from-history
Process
- Determine the rules target:
openspec/config.yamlif present, else.claude/reviewer/rules.yaml. If falling back to the portable target, confirmation of that target happens in the main conversation (via AskUserQuestion) before dispatch — not inside the agent. - Read the reviewer rules template
- Compare against existing rules (dedup by exact match)
- Append only new rules (or preview in dry-run mode)
- Report what was added
- With
--from-history: skip the static template — read the review findings history (openspec/reviews/history.jsonl, else.claude/reviewer/history.jsonl), cluster findings recurring across ≥2 changes into candidate rules, confirm each with the user (AskUserQuestion, multiSelect), and pass only confirmed rules to the agent as the template. Clustering and confirmation happen in the main conversation, NOT in the agent. The same pass flags existing rules for retirement — candidates are rules whose finding class never appears in history or that are superseded by a new candidate (never rules that went quiet after injection: that silence means they work). Removals get a separate AskUserQuestion and are applied with Edit in the main conversation; the injection agent stays append-only.
Agent Dispatch
Use the companion init-reviewer.md in this directory as the agent prompt. The agent will cd to the git root automatically. Provide it with:
- Whether dry_run mode is enabled
- The full content of the reviewer rules template
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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:init is a skill published in the GitHub repository shdennlin/agent-plugins (2 stars, last pushed today), licensed MIT. It adds 41 tokens to every session and 432 once invoked, about $0.0002 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 2026-09-11.

autoreview
Structured code review through the shared OpenClaw agent-skills installation.
omh-code-review
This is an OMH code-review workflow skill, projected for Agent Skills hosts (Claude Code, Codex, Cursor, opencode, OpenClaw, pi).
revdiff-plan
Review the last Codex assistant message (plan, analysis, or proposal) with inline annotations in a TUI overlay. Extracts the most recent response from Codex rollout files and opens it in revdiff for review and annotation. Activates on "revdiff-plan", "review plan with revdiff", "annotate plan", "review last response"…
asplos-writing-style
Use when drafting or revising ASPLOS prose — engineering the first two pages that rapid review actually reads, stating the cross-layer insight as one quotable sentence, structuring per-layer mechanism sections, writing bounded claims, and fitting everything into 11 self-contained pages that include figures and…
explore-unknowns
Guide the user through a quadrant walk that maps the unknowns of a task — open by listing the known knowns, then work through known unknowns, unknown knowns, and unknown unknowns one stage at a time, ending with a complete four-quadrant map in the user's hands. Use when a request is ambiguous or underspecified, the…
re0-merge
Review and land an external contribution the way this suite does: gate it against the thesis, land it with the author's credit intact, complete a new skill rather than merging it raw, then approve, credit, and explain before closing. Use when reviewing a pull request, as any collaborator or maintainer, not only the…
