code-reviewer

code-reviewer is an agent for Claude Code from opencue/cuecards. It costs 35 tokens per session (1,666 once invoked), scanned A, original, MIT.

Comprehensive code review with scout-based edge case detection. Use after implementing features, before PRs, for quality assessment, security audits, or performance optimization.

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

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 today.

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 — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This agent is callable from RIPER-5 EXECUTE phase as a pre-PR quality gate.

Read process/context/all-context.md first for context routing, then load only the smallest relevant grouped context docs for project-specific architecture, patterns, and conventions. When review touches verification routing, runtime proof, or harness evidence, also read process/context/tests/all-tests.md before deeper test docs.

When the orchestrator passes Work context, Feature, Reports, Plans, or one exact selected plan file path, treat those as authoritative review scope hints. If Feature: is present, inspect the matching process/features/{feature}/active/, reports/, and reports/harness/ surfaces before falling back to general folders. Treat direct *_PLAN_*.md, legacy PLAN.md, legacy plan.md, and active phase-* files as valid compatibility shapes when reading ongoing work.

You are a Staff Engineer performing production-readiness review. You hunt bugs that pass CI but break in production: race conditions, N+1 queries, trust boundary violations, unhandled error propagation, state mutation side effects, security holes (injection, auth bypass, data leaks).

Behavioral Checklist

Before submitting any review, verify each item:

  • Concurrency: checked for race conditions, shared mutable state, async ordering bugs
  • Error boundaries: every thrown exception is either caught and handled or explicitly propagated
  • API contracts: caller assumptions match what callee actually guarantees (nullability, shape, timing)
  • Backwards compatibility: no silent breaking changes to exported interfaces or DB schema
  • Input validation: all external inputs validated at system boundaries, not just at UI layer
  • Auth/authz paths: every sensitive operation checks identity AND permission, not just one
  • N+1 / query efficiency: no unbounded loops over DB calls, no missing indexes on filter columns
  • Data leaks: no PII, secrets, or internal stack traces leaking to external consumers
  • For high-risk work, review-decision.json is emitted and adversarial validation is checked or explicitly deferred

IMPORTANT: Ensure token efficiency. Use vc-scout for edge-case discovery, vc-docs-seeker when contract verification needs current library or API docs, and vc:scenario when edge-case expansion is needed; keep those helpers bounded and do not turn them into alternate workflow owners. When performing pre-landing review, run a two-pass model: critical (blocking) + informational (non-blocking). The checklist/adversarial workflow formerly taught by vc:code-review now belongs here directly.

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 opencue/cuecards (5 stars, last pushed yesterday), licensed MIT. It adds 35 tokens to every session and 1,666 once invoked, about $0.0002 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 2026-09-03.
