pm-tech-spec-review

pm-tech-spec-review is a skill for Claude Code from VandanaAjayDubey111/great-pm. It costs 83 tokens per session (1,318 once invoked), scanned A, original, MIT.

A review guide for checking an engineering technical specification against the product requirements. It looks for missing or added work, changes to user experience, and launch risks.

In plain words
What is it for?
Use it to compare technical designs with product requirements, find missing details, ask clarifying questions, and rank product risks.
Why use it?
Technical plans can accidentally drop requirements or expand the project. This review catches those gaps before implementation begins.

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

pm-tech-spec-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 26d 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.

How it starts

The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Codex host binding

  • Treat references to Claude slash workflows as the equivalently named Codex skill.
  • Before delegating to any specialist, read the great-pm-runtime skill and the selected packaged role file.
  • Treat "invoke", "assign", "delegate", "spawn", and source Agent-tool instructions as a required Codex spawn_agent call with that role and a bounded assignment.
  • For the spawn tool's task_name or agent_name identifier, replace canonical role-name hyphens with underscores (query-refiner-pm → query_refiner_pm). Keep canonical names unchanged in prompts, filenames, verdict logs, and user-facing output; this is an internal identifier mapping, not a role rename.
  • Store every returned agent identifier. Never call a wait tool until a spawn has returned an identifier, and wait only on identifiers returned by successful spawns.
  • If spawn_agent is unavailable or a spawn fails, report BLOCKED; do not impersonate the specialist or wait on an empty agent set.
  • Resolve bundled paths from the installed GreatPM plugin root.
  • Ignore Claude-only model aliases, colors, turn limits, and tool allowlists.
  • Preserve GreatPM human gates, governance, state, and reporting contracts.

PM-lens Technical Spec Review

Engineers write specs to answer "how do we build it?" A PM-lens review answers a different question the spec rarely asks itself: "does this build still deliver what we promised the user, all of it, and nothing we didn't agree to?" This sits between PRD sign-off and implementation — the cheapest place to catch a scope drift or a lost requirement.

This is distinct from:

  • Code review (does the code work / is it well-built) — that's code-reviewer.
  • PRD clarity check (is the PRD itself complete/testable) — that's prd-authoring / spec-reviewer's mechanical pass.
  • This skill: does the engineering plan honour the PRD's product intent.

Inputs

  • The technical spec / design doc / architecture proposal / API shape.
  • The original PRD or requirements it claims to implement.
  • The success metrics the feature is meant to move (if defined).

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.
