review

review is a skill for Claude Code from geniro-io/geniro-claude-harness. It costs 27 tokens per session (412 once invoked), scanned A, original, Apache-2.0.

A workflow for reviewing changes that are waiting to be committed, called a pending diff. It uses separate checks for bugs, security, and tests, verifies reported issues, and produces a severity-based report.

In plain words
What is it for?
Use it to inspect a code change before merging or committing, assess its test coverage, and organize confirmed findings by priority.
Why use it?
It helps catch real problems in changed code while removing findings that do not hold up when checked against the actual files.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: model in frontmatter; names the AskUserQuestion tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

review 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 11d 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

Review — pending-diff review

Phases overview

  1. Phase 0 — Triage. Resolve the diff and load custom instructions.
  2. Phase 1 — Reviewers. Spawn one reviewer per dimension in ONE response.
  3. Phase 2 — Verify. Re-read every cited location; drop what does not hold.
  4. Phase 3 — Report. Render the tiered table.

PHASE 0 — Triage

Resolve the diff. Apply ${CLAUDE_PLUGIN_ROOT}/skills/_shared/instruction-loader.md with SKILL_SLUG: review, LOAD_TIER: rules-only, MODE: initial-load. Extract the ## Rules block into $PROJECT_RULES for the Phase 1 spawn template.

PHASE 1 — Reviewers

Spawn one reviewer per dimension — bugs, security, tests — in ONE response; separate turns serialize the batch and double wall-time. Paste $PROJECT_RULES into each prompt.

Spawn geniro:coverage-agent alongside them to map which changed lines the suite exercises.

PHASE 2 — Verify

Read each cited location and confirm the quoted evidence is there. Drop the rest.

PHASE 3 — Report

Render the table, then offer the fix gate. Pass --legacy to emit the flat pre-2.0 report shape instead.

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.
