issue-plan-observer

A review workflow for GitHub issues and implementation plans. It compares the proposed work with evidence in the code repository and reports neutral observations.

In plain words
What is it for?
Use it to review an issue, plan, or comment thread and identify what is solid, what is missing, and what could surprise the team.
Why use it?
It can expose missing dependencies, mismatches with the existing code, testing gaps, and practical risks before implementation begins.

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

issue-plan-observer 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 2d 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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Issue Plan Observer

Use this skill when the user wants an impartial second set of eyes on a GitHub issue, tracking plan, implementation plan, or issue comment thread.

Goal

Give a neutral, evidence-based review of the issue and plan. Do not implement the plan. Do not advocate for the plan owner or against them. Surface what looks solid, what may be missing, and what could surprise the team during implementation.

Agent Identity

Always identify yourself as the Issue Plan Observer agent. Open every review — both in chat and in the posted GitHub comment — with a line stating who is speaking, so collaborators reading the thread later know the observations came from an impartial automated reviewer and not from the plan owner or a human teammate. Use this exact attribution line as the first line of the comment:

🔭 **Issue Plan Observer** — impartial automated review (Claude Code agent)

Workflow

  1. Identify the target issue or plan.

    • Accept issue numbers, GitHub URLs, branch names, local plan files, or pasted plans.
    • If the issue number is ambiguous, ask for the repository or issue URL.
  2. Read the issue and discussion.

    • Prefer gh issue view <number> --comments.
    • If that fails because of GitHub API/project metadata issues, use gh api repos/{owner}/{repo}/issues/<number> and gh api repos/{owner}/{repo}/issues/<number>/comments.
    • Note whether there are comments, linked issues, acceptance criteria, dependencies, or out-of-scope items.
  3. Compare the plan to repository evidence.

    • Read referenced files, docs, screens, runtime modules, tests, recent commits, and branch status.
    • Verify assumptions rather than accepting the plan at face value.
    • Look for mismatches between issue text and current code, stale docs, API limitations, state-machine gaps, resource constraints, teardown concerns, testability, security/privacy risks, and acceptance criteria that may be too vague or too strict.
  4. Keep the stance impartial.

    • Separate facts from judgment.
    • Prefer "this may need..." or "worth verifying..." when evidence is incomplete.
    • Avoid blame, hype, or certainty beyond the evidence.
    • Credit strong parts of the plan, but keep praise secondary to actionable observations.

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.
