# Modify Feature Apply changes to existing features using spec-first workflow. **Architecture Reference:** @../_shared/patterns.md ## Hook Marker (Required) Before editing any feature files, activate the skill marker so the PreToolUse hook allows edits: ```bash touch /tmp/.claude-kmpilot-skill-active ``` After completion (or on any early exit), remove it: ```bash rm -f /tmp/.claude-kmpilot-skill-active ``` ## Workflow **Parse** → **Spec Check** → **Design Artifact Detection** → **Understand** → **Plan** → **Draft Spec** → [USER APPROVES] → **Activate marker** → **Implement** → **Validate** → **Update Spec** → **Remove marker** → Done ### Step 1: Parse Feature Name Extract from request: "add sorting to productlist" → `productlist` Validate: `ls feature/{featurename}/src/commonMain/kotlin/` ### Step 2: Spec Check Load `.claude/docs/{featurename}/spec.md` If missing, **stop and instruct the user**: ``` No spec found for '{featurename}'. Please run /audit-spec {featurename} first to generate one, then re-invoke /modify-feature. ``` Do NOT auto-invoke `/audit-spec` — skills do not call each other; the user controls the pipeline. ### Step 3: Design Artifact Detection Check for a Stitch design blueprint: 1. **Check blueprint exists**: `.claude/docs/{featurename}/designs/{featurename}_blueprint.md` 2. **Check stitch-project.json**: `.claude/docs/_project/stitch-project.json` — read `features[featurename].blueprintConsumed` 3. **Determine mode**: | Blueprint exists? | `...
