planifie

planifie is a skill for Claude Code from naiersaidane/claude-mastery. It costs 146 tokens per session (1,124 once invoked), scanned A, original, MIT.

A planning process that turns a product requirements document, or PRD, into independently deliverable development phases. It records architectural decisions, user stories, outputs, acceptance checks, and dependencies in docs/PLAN.md.

In plain words
What is it for?
Use it to plan work from docs/PRD.md, extend an existing development plan, understand the current code structure, and define how each phase will be accepted.
Why use it?
It breaks a large project into smaller vertical slices that can each be delivered and checked. It also compares an existing plan with updated requirements and avoids rewriting approved phases.

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

planifie 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 11d 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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/planifie

Découpe un PRD en phases indépendamment livrables par tranches verticales (tracer bullets). Sortie dans docs/PLAN.md.

Process

1. Récupère le PRD

Par défaut, lis docs/PRD.md. Si un chemin de fichier est passé en argument, lis-le. Si rien d'utilisable, demande à l'utilisateur de pointer le fichier ou de coller le contenu.

2. Mode extension si PLAN existe

Si docs/PLAN.md existe déjà, lis-le. Repère les user stories du PRD non couvertes par une phase existante et les incohérences avec un PRD qui a bougé. Ne réécris pas les phases déjà validées ; propose des phases additionnelles ou des extensions ciblées, et signale les contradictions à l'utilisateur avant d'écrire.

3. Explore le codebase

Si tu n'as pas déjà exploré le codebase, fais-le pour comprendre l'architecture actuelle, les patterns en place et les couches d'intégration. Si le projet est vierge (greenfield), saute cette étape.

4. Identifie les décisions architecturales durables

Avant de découper, identifie les décisions de haut niveau qui ne devraient pas bouger en cours d'implémentation :

  • Structure des routes / patterns d'URL
  • Forme du schéma de base de données
  • Noms des modèles de données clés
  • Approche d'authentification / autorisation
  • Frontières des services tiers

Elles vont dans l'en-tête du plan, chaque phase peut s'y référer.

5. Drafte les tranches verticales

Découpe le PRD en phases tracer bullets. Chaque phase est une tranche fine qui traverse TOUTES les couches d'intégration de bout en bout, PAS une tranche horizontale d'une seule couche.

<règles-tranche-verticale>

  • Chaque tranche livre un chemin étroit mais COMPLET à travers toutes les couches (schema, API, UI, tests)
  • Une tranche terminée est démontrable ou vérifiable seule
  • Préfère beaucoup de tranches fines à peu de tranches épaisses
  • N'inclus PAS les noms de fichiers, noms de fonctions, ou détails d'implémentation susceptibles de changer
  • INCLUS les décisions durables : routes, formes de schéma, noms de modèles </règles-tranche-verticale>

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.
