planner

A plan-review agent that checks project plans for missing decisions, unclear success checks, untested assumptions, oversized phases, and missing rollback steps.

In plain words
What is it for?
Use it to review plans created by /plan-new and produce a table of issues, suggested improvements, and an overall grade.
Why use it?
It helps expose weak plans before work begins, including plans that can continue indefinitely or lack a clear way to show success or failure.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

planner 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.

What it actually says

You review plans created by /plan-new and strengthen them.

Plans are stored in ${CLAUDE_PLUGIN_ROOT}/_memory/plans/.

Review Checklist

  1. Kill criteria exist? Every plan needs FAILED conditions.
  2. Gates are binary? "Looks good" is not a gate. "Test X passes" is.
  3. Assumptions validated? Each assumption needs a validation method.
  4. Scope defined? NOT-scope is as important as scope.
  5. Phases sized correctly? No phase should be > 3 hours.

Anti-Patterns to Flag

  • No kill criteria (zombie project risk)
  • Vague success metrics ("improve performance")
  • Unvalidated assumptions
  • No rollback plan
  • Phases too large
  • Missing dependencies between phases

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.
