plan-review

plan-review is a skill for Claude Code, Codex from kdcokenny/ocx. It costs 11 tokens per session (1,037 once invoked), scanned A, original, MIT.

A checklist for reviewing implementation plans before they are carried out. It checks whether decisions are supported by citations, whether the plan covers the needed work, and whether its instructions are actionable.

In plain words
What is it for?
Use it to audit a saved plan, review a plan before execution, verify research references, and check that proposed steps can be followed.
Why use it?
It helps catch plans that make unsupported claims, omit important work, or lack enough detail for someone else to implement them. The plan's basic file structure is assumed to have been checked already.

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

plan-review 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.

Plan Review

Load this skill when reviewing implementation plans (not code).

TL;DR

Systematic plan review focused on 3 quality categories: Citation Quality, Completeness, and Actionability. Structure is pre-validated by plan_save—focus on whether the plan provides actionable implementation guidance.

When to Use This Skill

  • When reviewing implementation plans before execution
  • When auditing plan quality after creation
  • When verifying plans meet documentation standards
  • As part of the plan validation workflow

Plan Review Checklist

1. Structure (Pre-validated)

Note: Saved plans are structurally validated by plan_save before storage. Format compliance (YAML frontmatter, status markers, CURRENT marker, numbering) is guaranteed. Focus your review on the quality aspects below.

2. Citation Quality

Requirement Check
Decisions reference sources ref:delegation-id format used
No unsubstantiated claims Architectural decisions cite research
Research phases show refs Completed research tasks include citations
Citations are verifiable IDs match actual delegation outputs

Red Flags:

  • Decisions table with empty or - in Source column
  • Claims like "industry standard" or "best practice" without citation
  • Research tasks marked complete without → ref:id

3. Completeness

Requirement Check
Goal is specific Measurable outcome, not vague intent
Phases are logical Sequential, with clear progression
Edge cases considered Error handling, failure modes addressed
Notes section present Key decisions and observations documented
Context & Decisions table Captures architectural choices with rationale

Goal Quality Examples:

  • ❌ "Improve authentication" (vague)
  • ❌ "Make it better" (unmeasurable)
  • ✅ "Add JWT authentication with refresh token support" (specific)
  • ✅ "Migrate user table to PostgreSQL with zero downtime" (measurable)

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.
