deep-code-review

deep-code-review is a skill for Claude Code, Codex from Peaky8linders/eu-ai-act-scanner. It costs 34 tokens per session (2,177 once invoked), scanned A, original, Apache-2.0.

A thorough review method for finding bugs in the current Git branch before it is merged. It uses multiple specialist reviewers, checks their findings to remove false alarms, ranks issues by severity, and saves a report.

In plain words
What is it for?
Use it to review a branch against the main branch, investigate bugs, and prepare a persistent report for human review before merging.
Why use it?
It gives a structured second look at local changes before they reach the main codebase. Verification helps distinguish real defects from suspected problems.

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

deep-code-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 8d 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.

Deep Code Review

Multi-agent bug-hunting review of the current branch against main. Dispatches specialist agents in parallel, verifies findings to filter false positives, ranks by severity, and produces a persistent report.

This is a technique skill. Follow the phases in order. Do not skip verification.

Pre-flight Checks

digraph preflight {
  "Conversation has history?" [shape=diamond];
  "On main/master?" [shape=diamond];
  "Uncommitted changes?" [shape=diamond];
  "Proceed to Phase 1" [shape=box];
  "STOP: recommend new session" [shape=box, style=bold];
  "STOP: nothing to review" [shape=box, style=bold];
  "WARN: ask user" [shape=box];

  "Conversation has history?" -> "STOP: recommend new session" [label="yes"];
  "Conversation has history?" -> "On main/master?" [label="no"];
  "On main/master?" -> "STOP: nothing to review" [label="yes"];
  "On main/master?" -> "Uncommitted changes?" [label="no"];
  "Uncommitted changes?" -> "WARN: ask user" [label="yes"];
  "Uncommitted changes?" -> "Proceed to Phase 1" [label="no"];
  "WARN: ask user" -> "Proceed to Phase 1" [label="user decides"];
}
  1. Context window: If conversation has substantive history beyond invoking this skill, tell the user: "This review consumes significant context. Start a fresh session with /deep-code-review to avoid context rot." Stop and wait.
  2. Branch: Must not be on main/master. If so, stop.
  3. Clean state: If uncommitted changes exist, ask: review committed state only, or wait to commit?

Phase 1: Reconnaissance

Run these commands and collect results:

  1. git diff --stat main...HEAD — files and line counts
  2. git diff main...HEAD — full diff content
  3. Classify diff size:
    • Small: <50 lines changed
    • Medium: 50-500 lines changed
    • Large: 500+ lines changed
  4. Scan for plan/design docs: docs/plans/, aidlc-docs/, or similar
  5. Scan for steering files: CLAUDE.md, AGENTS.md, etc.
  6. For each changed file, grep for callers/callees one level deep (function/method names from the diff)
  7. When the diff includes infrastructure files (schema migrations, build configs, CI pipelines, environment templates), check whether test-side counterparts exist (e.g., test resource directories with their own migrations, test-specific configs). Add any unmatched test infrastructure to the manifest for the Contract & Integration specialist.
  8. For small diffs: expand scope to full module/package for each changed file
  9. Build manifest: files to review (changed + adjacent), grouped for specialists

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.
