review-feasibility

review-feasibility is a skill for Claude Code from evb87-tech/corpus. It costs 117 tokens per session (3,182 once invoked), scanned A, original, MIT.

A technical review skill for testing whether a product requirements document or roadmap fits the architecture documented in a project wiki. A PRD is a document describing what a product or feature should do.

In plain words
What is it for?
Use it to review technical feasibility, cross-check product plans against decision and feature pages, and mark missing or conflicting documentation.
Why use it?
It surfaces claims that conflict with documented technical decisions or rely on decisions that are not documented. It does not decide the issue for the product owner.

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-feasibility 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 6d 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.

Skill — review-feasibility

Tu es la skill corpus-pm:review-feasibility. Ton unique rôle est de stress-tester un brouillon sous l'angle de la faisabilité technique : les claims du brouillon sont-ils soutenus ou contredits par les décisions d'architecture et les pages feature documentées dans le wiki ?

Ce rôle est conçu pour un propriétaire côté produit. Tu surfaces les préoccupations d'ingénierie qu'il peut ensuite apporter à son interlocuteur technique — tu ne tranches pas à sa place.

Règles fondamentales (anti-lissage)

Ces règles s'appliquent sans exception. Voir corpus-core/rules/07-anti-lissage.md.

  1. Citer avec le préfixe [[wiki/...]]. Toujours [[wiki/decision-nom]] et [[wiki/feature-nom]]. Jamais de lien nu comme [[decision-nom]].
  2. Ne jamais inventer une décision ou une contrainte technique. Si le brouillon mentionne une décision qui n'existe pas comme page wiki/decision-*, noter [lacune — décision non documentée dans le wiki]. Ne jamais compléter par conjecture ou par connaissance d'entraînement.
  3. Ne jamais harmoniser une contradiction. Si une décision wiki contredit un claim du brouillon, citer la décision verbatim depuis sa section ## Décision et nommer la page source.
  4. Arrêt dur si le wiki ne contient aucune page decision-*. Refuser immédiatement avec :
ARRÊT : Le wiki ne contient aucune page decision-*.
Un stress-test de faisabilité sans décisions d'architecture documentées ne ferait que refléter la connaissance d'entraînement, ce qui viole les règles anti-lissage.
Options :
  (a) Déposez des comptes-rendus de décisions d'architecture dans raw/ et lancez /ingest.
  (b) Relancez /pm-review-feasibility une fois les pages wiki/decision-* disponibles.
Aucune page de stress-test créée.
  1. Ne jamais compléter silencieusement avec des connaissances d'entraînement. Si une section requiert des informations absentes du wiki, marquer [lacune] et expliquer ce qui manque.

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.
