feature

feature is a skill for Claude Code from GlamgarOnDiscord/claude-saas-blueprint. It costs 24 tokens per session (528 once invoked), scanned A, original, MIT.

A skill for implementing a SaaS feature from exploration through planning, coding, and verification using several structured steps.

In plain words
What is it for?
Use it to explore the existing project, plan the architecture, implement the feature in layers, and verify the result with tests.
Why use it?
It breaks complex feature work into separate stages so important codebase constraints, documentation, and tests are not overlooked.

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

feature 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.

What it actually says

Arguments

  • description : Description de la feature à implémenter

Architecture Multi-Step (Prompt Discovery)

Cette skill utilise des étapes séparées pour éviter le "Lost in the Middle". Chaque étape est dans un fichier distinct — l'instruction en cours est toujours la plus récente dans le contexte.

Orchestration

Étape 1 — EXPLORE (obligatoire)

Lire et exécuter .claude/skills/feature/steps/step-1-explore.md

  • Lancer 3 sous-agents en parallèle (codebase, doc externe, rules)
  • Synthétiser les résultats
  • Ne PAS passer à l'étape 2 tant que l'exploration n'est pas terminée

Étape 2 — PLAN (obligatoire)

Lire et exécuter .claude/skills/feature/steps/step-2-plan.md

  • Créer le plan d'architecture (core → adapters → UI → tests)
  • Si blast radius > 5 fichiers → EnterPlanMode pour approbation
  • Ne PAS passer à l'étape 3 sans plan validé

Étape 3 — EXECUTE

Lire et exécuter .claude/skills/feature/steps/step-3-execute.md

  • Implémenter étape par étape en respectant l'ordre strict
  • Lire la rule contextuelle AVANT chaque type de fichier modifié
  • Paralléliser la génération de tests via sous-agent

Étape 4 — VERIFY (obligatoire, jamais skip)

Lire et exécuter .claude/skills/feature/steps/step-4-verify.md

  • 6 checks : types, lint, tests, sécurité, architecture, visuel
  • Si erreur découverte → ajouter dans rules/_learned.md
  • Mettre à jour la memory (domains, roadmap, session)

Important

  • Chaque étape est un fichier séparé — lire le fichier de l'étape en cours, pas tous d'un coup
  • Ne JAMAIS sauter une étape — l'exploration et la planification sont obligatoires
  • Fail-stop : 2 échecs consécutifs sur une étape → arrêt + demande utilisateur
Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
