Why use it?
It helps find gaps or problems in a plan before implementation begins.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: mentions Claude Code; mentions Codex.

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-plan 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/volley:review-plan

Hand a plan to Codex. Get back a review. Write it to disk, show it inline.

Steps for Claude

  1. Verify .volley/ is initialized and the lock allows Claude to act.

    [ -d .volley ] || { echo "ERROR: .volley/ not found. Run /volley:setup first." >&2; exit 1; }
    [ -f .volley/STATE ] || { echo "ERROR: .volley/STATE not found. Run /volley:setup first." >&2; exit 1; }
    . "${CLAUDE_PLUGIN_ROOT}/scripts/lib.sh"
    volley_state_assert_active .volley/STATE claude || exit 1
    

    If the assert fails, the helper already printed a refusal message. Stop.

  2. Resolve the plan path.

    • If user passed a path argument, use it.
    • Otherwise: ls -t .planning/**/PLAN.md 2>/dev/null | head -1 (or use Glob tool with pattern .planning/**/PLAN.md and take the most recent by mtime).
    • If no plan found, tell user "No PLAN.md found under .planning/. Pass an explicit path, or check that you've run /gsd:plan-phase to create one." and stop.
  3. Read the plan and HANDOFF.

    • Read the plan file's full content.
    • Read .volley/HANDOFF.md for acceptance criteria.
  4. Build the review prompt for Codex.

    The prompt to send via mcp__codex__codex (the only Codex session-start tool the MCP server exposes; older docs may say mcp__codex__review or mcp__codex__exec - those names are wrong):

    You are reviewing an implementation plan. Be specific and concrete.
    
    ACCEPTANCE CRITERIA (from HANDOFF.md):
    <paste HANDOFF.md content>
    
    PLAN TO REVIEW:
    <paste plan content>
    
    Provide your review in this format:
    
    ## Verdict
    APPROVE | CONCERNS | REJECT
    
    ## Strengths
    - (specific things the plan gets right)
    
    ## Concerns
    - (specific issues, with file/line refs from the plan if applicable)
    
    ## Suggested changes
    - (concrete edits, not vague advice)
    
    Keep it under 500 words. Skip filler.
    
  5. Resolve the review role's model/effort/context from config. Read .volley/config.json (parse it yourself; absent = defaults). Take codex.review.model, codex.review.reasoningEffort, and apply any .volley/local.json modelOverrides.review. Check context.required files all exist - if any is missing, stop with a clear error naming the file (fail early). Note which context.optional files exist; missing optional files are reported and skipped.

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.
