plan-review

A structured review that tests a product, system, migration, or launch plan before work begins. It checks the plan’s assumptions, dependencies, evidence, and possible ways it could fail.

In plain words
What is it for?
Use it for pre-mortems, strategy checks, scope reviews, and independent challenges to a plan. It can examine business goals, user experience, or technical design, but it does not write code.
Why use it?
It helps find costly mistakes while changes are still easy. It separates confirmed problems from risks, assumptions, and open questions.

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 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.

Plan Review

Improve a plan by attacking its load-bearing assumptions while course correction is still cheap.

Review Boundary

  • Review only unless the user explicitly requests revisions or implementation.
  • Read the plan, its source requirements, repository reality, and available evidence. Do not review a summary when the full artifact is available.
  • Steelman the intended outcome before criticizing the approach.
  • Prefer five decision-changing findings over a long generic risk list.
  • Do not inflate scope in the name of ambition. The strongest review may recommend a smaller plan, a cheaper test, or no build.
  • Separate verified conflicts, evidence-backed risks, assumptions, and questions.

Lenses

Apply the lenses relevant to the plan and name which were used:

  • Founder: Target user, painful job, wedge, why now, distribution, switching, monetization, defensibility, and kill assumptions.
  • Product: Journey completeness, independent value, success metrics, guardrails, accessibility, trust, support, and learning loop.
  • Engineering: Architecture, data flow, interfaces, invariants, failure handling, security, privacy, performance, compatibility, and maintainability.
  • Delivery: Dependency order, vertical slices, test seams, migrations, observability, rollout, rollback, operational ownership, and authority boundaries.

Workflow

  1. Reconstruct intent: State the desired outcome, non-goals, constraints, evidence, and proof required for completion.
  2. Inspect current reality: Verify relevant source paths, interfaces, dependencies, runtime assumptions, and existing mechanisms the plan proposes to replace or duplicate.
  3. Map claims: Extract the decisions and assumptions on which the plan depends. Identify any requirement with no task, task with no requirement, or success claim with no proof.
  4. Challenge the premise: Ask whether the problem is real, the chosen scope is the smallest useful wedge, and a no-build or manual alternative could learn more cheaply.
  5. Attack failure modes: Imagine the plan failed through lack of value, integration breakage, data loss, abuse, operational burden, migration, adoption, or rollback failure. Trace concrete chains rather than naming categories.
  6. Test intended versus planned: Compare documented permissions, user journeys, data rules, and operational promises with the actual tasks and verification steps.
  7. Rank findings: Score each issue by impact, likelihood, confidence, and cheapness to test. Promote only issues that could change the decision or execution order.
  8. Offer remedies: Give the smallest corrective change, cheapest decisive test, and kill or rollback criterion. Present numbered alternatives when a real trade-off remains.
  9. Issue a verdict: Return ACCEPT, ACCEPT WITH CHANGES, REVISE, or STOP AND TEST, with the minimum conditions for the next state.

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.

plan-review is a skill published in the GitHub repository fmind/dotfiles (4 stars, last pushed 2d ago), licensed MIT. It adds 47 tokens to every session and 986 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

dotfiles-bootstrap

Bootstrap a workstation with the dotfiles framework. Takes a GitHub user / owner+repo / explicit clone URL and runs dot init (which shells out to chezmoi) with the right safety prompts. Honors the active agent profile (ask / plan / apply / audit) so it defaults to dry-run in safer modes and full apply in apply.
