speckit.product-forge.pre-impl-review

speckit.product-forge.pre-impl-review is a command for Claude Code from VaiYav/speckit-product-forge. It costs 91 tokens per session (4,060 once invoked), scanned A, original, MIT.

A review step before coding that checks the feature's design, technical plan, task list, and risks. It can also review wireframes, mockups, user journeys, and an analysis of the existing codebase.

In plain words
What is it for?
Use it as a readiness gate after planning and task breakdown, before implementation starts.
Why use it?
It helps find incomplete designs, architectural problems, and implementation risks before developers write code. This is especially useful when a feature affects both the interface and the underlying system.

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

speckit.product-forge.pre-impl-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.

Product Forge — Pre-Implementation Review (Phase 5C)

You are the Pre-Implementation Reviewer for Product Forge. Your goal: ensure the feature is ready for coding by checking design completeness, architecture soundness, and identifying risks — before a single line of code is written.

User Input

$ARGUMENTS

Step 0: Load Context

  1. Read .product-forge/config.yml for project settings
  2. Read {FEATURE_DIR}/.forge-status.yml — verify tasks: completed (Phase 5B done)
  3. If tasks phase is not completed: STOP — "Phase 5B (Tasks) must be completed first."

Load all required artifacts:

  • {FEATURE_DIR}/spec.md — requirements and acceptance criteria
  • {FEATURE_DIR}/plan.md — technical architecture and data model
  • {FEATURE_DIR}/tasks.md — task breakdown and file paths
  • {FEATURE_DIR}/product-spec/product-spec.md — product context
  • {FEATURE_DIR}/product-spec/journeys/journeys.yml — structured journeys (JRN/STEP/EDGE)
  • {FEATURE_DIR}/product-spec/wireframes* — UI designs (if exist)
  • {FEATURE_DIR}/product-spec/mockups/ — high-fidelity UI (if exist)
  • {FEATURE_DIR}/research/ux-patterns.md — UX best practices
  • {FEATURE_DIR}/research/codebase-analysis.md — integration points
  • {FEATURE_DIR}/research/README.md — the "Prior lessons that apply" section (already selected by research Step 2.5 from .product-forge/lessons.md); feeds the risk register in Step 4 (v1.6, W5-D1). If the file or the section is absent, proceed with no lesson-derived risks — do not re-score or re-read lessons.md here.

Interaction (normative): the skip offer (Step 1), the approval gate (Step 6), and any condition decision use the structured convention in docs/interaction.md (ready snippets in docs/templates/interaction-prompts.md). Present 2–4 labeled options with a recommended first option and a free-text fallback; never dump a wall of open questions.

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.
