review-plan

review-plan is a command for Claude Code from mvpasarel/gh-copilot-plugin-cc. It costs 10 tokens per session (495 once invoked), scanned A, original, Apache-2.0.

A command that checks an implementation plan for accuracy, completeness, and whether it can realistically be carried out. It only reports its review and does not change the plan or code.

In plain words
What is it for?
Use it to review plans passed as text, a file, or standard input, either while waiting for the result or as a background job.
Why use it?
It helps catch missing steps, incorrect assumptions, and impractical work before implementation begins.

Command for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: 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-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 9d 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 an implementation plan via Copilot.

Raw slash-command arguments: $ARGUMENTS

Core constraint:

  • This command is review-only.
  • Do not fix issues in the plan, apply patches, or suggest that you are about to make changes.
  • Your only job is to run the review and return Copilot's output verbatim to the user.

Execution mode rules:

  • If the raw arguments include --background, do not ask. Run in a Claude background job.
  • If the raw arguments include --wait, do not ask. Run in the foreground.
  • Otherwise, default recommendation is background for plans of non-trivial size.
    • Recommend foreground only for clearly small, simple plans.
    • In every other case, recommend background.
  • Use AskUserQuestion exactly once with two options, putting the recommended option first and suffixing its label with (Recommended):
    • Wait for results
    • Run in background

Argument handling:

  • Preserve the user's arguments exactly.
  • Plan content can be passed as positional arguments, via --plan-file <path>, or piped via stdin.
  • Do not strip --background or --wait yourself.

Foreground flow:

  • Run:
node "${CLAUDE_PLUGIN_ROOT}/scripts/copilot-companion.mjs" review-plan "$ARGUMENTS"
  • Return the command stdout verbatim, exactly as-is.
  • Do not paraphrase, summarize, or add commentary before or after it.

Background flow:

  • Launch with Bash in the background:
Bash({
  command: `node "${CLAUDE_PLUGIN_ROOT}/scripts/copilot-companion.mjs" review-plan "$ARGUMENTS"`,
  description: "Copilot plan review",
  run_in_background: true
})
  • Do not call BashOutput or wait for completion in this turn.
  • After launching the command, tell the user: "Copilot plan review started in the background. Check /copilot:status for progress."

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.
