review-feat-plan

review-feat-plan is a command for Claude Code from nicelight/DevRails-26. It costs 13 tokens per session (1,196 once invoked), scanned A, original, MIT.

A review command for checking whether a product requirements document has been broken into a sound feature plan. It uses a fresh review context and returns either APPROVE or REJECT.

In plain words
What is it for?
Use it to review product briefs, requirements, epics, features, and specifications before implementation planning.
Why use it?
It catches missing, conflicting, or poorly divided product work before detailed system design begins. It keeps this review separate from the later task-plan review.

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-feat-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 8d 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.

/review-feat-plan - Feature plan review

The verdict vocabulary remains APPROVE|REJECT. This review does not inspect JSON task design; /review-tasks-plan owns that later gate.

<input_contract> Read when present and relevant:

  • Constitution, Product Brief, analysis index, and clarified PRD;
  • product, requirements, epics, and product features;
  • spec-index and spec-backbone.

Do not require task records. If they already exist, ignore implementation detail except for an obvious stale contradiction with the current product plan. </input_contract>

<hard_invariants>

  • Use a fresh-context reviewer or separate fresh session.
  • Before the verdict, load and apply this installed skill's references/finding-adjudication.md semantic pack.
  • Reviewer reports findings only. It does not rewrite product decisions or choose between ambiguous alternatives.
  • FT-000 remains reserved for Foundation Dev Path.
  • REJECT is blocking; APPROVE may include non-blocking notes.
  • High-risk, large, and autonomous flows require APPROVE; small manual flows use this gate when required by the operator/Constitution or as recommended. </hard_invariants>

<operator_decisions> If correctness depends on an unresolved product/decomposition choice, return REJECT with the exact question, affected artifacts, decision owner, and repair route. A reviewer recommendation may accompany the question but must not be applied as the operator's decision. </operator_decisions>

<required_outputs> Create:

  • .tasks/TASK-MB-REVIEW-FEAT-PLAN/REQUEST.md;
  • .tasks/TASK-MB-REVIEW-FEAT-PLAN/TASK-MB-REVIEW-FEAT-PLAN-<STAGE_ID>-final-report-docs-01.md.

The report must contain VERDICT: APPROVE|REJECT, evidence, blocking findings, non-blocking notes, unresolved operator questions, and the owning repair route.

Use TASK_ID=TASK-MB-REVIEW-FEAT-PLAN and STAGE_ID=S-FEAT. The bounded reviewer request must name the inputs above, the output path ending in TASK-MB-REVIEW-FEAT-PLAN-S-FEAT-final-report-docs-01.md, the APPROVE|REJECT vocabulary, and the prohibition on reviewing task implementation detail. This is the reviewer handoff contract; review order and probes remain discretionary. </required_outputs>

<agent_discretion> Choose review order, search tools, working-note shape, additional probes, and depth proportional to risk and evidence. The review dimensions below are coverage criteria, not a required reasoning script:

  • clarified PRD and Constitution consistency;
  • stable REQ-* IDs and no unsupported scope;
  • PRD -> REQ -> EP -> FT traceability, including Product Brief/analysis when present;
  • stable unique FT-<NNN>-AC-<NNN> IDs under each feature's ## Acceptance Criteria, matching the owning feature and linked to existing governing REQ-*;
  • acceptance closure for material outcomes: each material edge/failure maps to a feature AC or a sourced authoritative out-of-scope disposition with /write-prd change route; each material NFR has an accepted observable target/qualitative criterion, decisive conditions, and verification method across its governing REQ and feature AC;
  • coherent feature value, sizing, boundaries, acceptance, and failure behavior;
  • where evidence shows multiple acceptance outcomes, lifecycle/release units, or actor/authority/boundary paths, one bounded falsification probe asks whether a concrete second product slice has its own observable value and acceptance and can be verified or released independently;
  • truthful clarification_status: pending|blocked handling;
  • no bypass from analysis to tasking around /write-prd, /spec-init, /prd-to-features, /spec-design, or required Foundation Dev Path;
  • FT-000 reservation;
  • visible Foundation pressure signals for /spec-design without creating foundation tasks here. </agent_discretion>

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.
