SDD-Pro

Use when the user reports that an SDDPro pipeline failed, a build errored, tests failed, the API Gate is RED, the spec-compliance gate failed, an auditor returned RED, or any other SDDPro step blocked. Triggers on phrases like "ça plante", "le build échoue", "API gate RED", "/sdd-full failed", "tests failed", "coverage < seuil". Routes to a deterministic diagnostic via /sdd-status + /sdd-help + reading the relevant report under workspace/output/qa/. Refuses to "just fix the code" without first understanding what gate produced the RED.

Use when the user expresses intent to add a new feature, capability, or functionality to the project. Triggers on phrases like "I want to add", "we need a", "new feature", "let's build", "implement X", "ajouter une fonctionnalité", "nouvelle feature". Routes to the SDDPro /feat-generate pipeline instead of letting the agent jump into coding. Captures Phase 0 Discovery if the project is greenfield with no Discovery artifacts.

Use when the user expresses intent to reverse-engineer a legacy application, convert old code into SDD_Pro specifications, or migrate a brownfield project. Triggers on phrases like "reverse engineering", "reverse engineer", "convertir l'ancien système", "convertir le legacy", "j'ai un legacy", "j'ai une vieille application", "rétroingénierie", "ingénierie inverse", "moderniser l'application legacy", "migrer le legacy", "migration legacy", "workspace/old", explicit "/sdd-reverse" mention. Routes to the SDD_Pro reverse engineering workflow (separate from the main /sdd-full pipeline) and prevents Claude from jumping into ad-hoc analysis without phased extraction. Conservative triggering: does NOT activate on generic "vieux code" or "convertir" alone.

Use whenever the agent is about to write production code (a new function, class, endpoint, method, or component) to enforce the RED-GREEN-REFACTOR cycle (emprunt Superpowers v5.1). NO production code without a failing test first. Triggers on intentions to write code into workspace/output/src/, *.cs/*.ts/*.py/*.kt files, or any creation of a method/class/function/endpoint. If the agent realizes it has already written production code without a test, the skill mandates deleting that code and restarting with RED-GREEN-REFACTOR. Non-negotiable for SDDPro v7.0.0+ test-first contract.

Use IMMEDIATELY at session start, before responding to any user message about software development, feature additions, bug fixes, code reviews, or anything that could be done with SDDPro framework commands. Loads the canonical SDDPro pipeline overview, the 13 user-facing commands, and the agent ownership model so subsequent responses route through framework conventions instead of ad-hoc coding.
