codebase-review-swarm

codebase-review-swarm is a skill for Codex from ZaxbyHub/opencode-swarm. It costs 54 tokens per session (331 once invoked), scanned A, original, MIT.

A read-only workflow for reviewing a whole codebase or a large part of it for security, quality, accessibility, performance, AI-generated coding problems, or possible improvements. It requires claims to be supported by direct quotes or other recorded evidence.

In plain words
What is it for?
Use it for full-repository audits, security reviews, QA checks, accessibility and performance reviews, or enhancement reports.
Why use it?
It creates a structured review record while preventing source changes during the audit. It also makes missing or incomplete review coverage explicit.

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

codebase-review-swarm 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.

Codex Execution Notes

  • Treat this as a read-only review workflow. Do not modify source files.
  • Write review artifacts only under .swarm/review-v8/runs/<run_id>/.
  • Run Phase 0 inventory first and stop for review-mode selection unless the user already selected tracks and explicitly authorized continuing.
  • Preserve the skill's evidence rule: no quote, no claim.
  • For dispatch lanes, only if the session actually exposes the controller's lane tools, treat output as a preview and call retrieve_lane_output for full output_ref artifacts before consuming ledgers, counting candidates, routing validation, or declaring coverage clean; when those tools are absent, treat inline output as the full artifact and disclose any truncation as an explicit coverage limitation.
  • Use rg, focused file reads, targeted shell commands, and independent validation to close coverage units before writing the final report.
  • If the user asks for fixes after the report, start a separate implementation workflow rather than editing during the review run.
Files

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.

Changes

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.
