Localiser composant UI

---

name: find-component description: >- [Frontend] Find source code components from UI screenshots or visual descriptions. Runs BEFORE /scout when screenshot is pasted with UI intent. Triggers on: find component, find this component, where is this code, where is this page, which component, locate component, find the source, what component is this, refresh component index, update component index, sync component index. Maps visual signals to source files with confidence scoring and Mermaid component graph. allowed-tools: Read, Grep, Glob, Bash, Task

Anti-Hallucination Requirement

Read: .claude/skills/shared/anti-hallucination-protocol.md Read: references/confidence-scoring-guide.md

Every claimed match MUST have grep-verified evidence. HALT if confidence <85% — show candidates, never fabricate.

Workflow

Step 1: Load Component Index

# Full scan (rebuild entire index):
node .claude/skills/find-component/scripts/generate-component-index.cjs

# Incremental (only re-scan git-changed component files):
node .claude/skills/find-component/scripts/generate-component-index.cjs --git-changes

# Then read:
Read: docs/component-index.json

When to use which mode:

• --git-changes — fast update after editing components (merges into existing index)
• No flag — full rebuild when index missing, stale, or after major refactors
• Fallback: live grep if index unavailable

Step 2: Extract Visual Signals from Screenshot

Read: references/visual-signal-extraction.md

Read the screenshot. Extract 6 signal types (text, BEM, Material, layout, color, data shape). List each signal with what you ACTUALLY see — never infer.

Step 3: Bottom-Up Component Search

Read: references/component-matching-protocol.md

1. Reusable components first — match signals against platform-core/ and libs/ components
2. Domain components — match against shared/components/
3. Page component — find parent that composes matched children
4. If no reusable match → search page templates directly

Step 4: Score Confidence

Read: references/confidence-scoring-guide.md

• ≥85% (≥2 grep-verified signals) → report as confirmed match
• <85% → show top candidates with per-signal breakdown, ask user

Step 5: Build Component Relationship Graph

Output Mermaid diagram:

graph TD
  A[PageComponent] --> B[ChildComponent1]
  A --> C[ChildComponent2]
  B --> D[SharedComponent]

Verify each edge by reading actual template HTML. Never infer from imports alone.

Step 6: Report

Output: matched components, file paths (TS/HTML/SCSS), confidence %, Mermaid graph, and any unresolved ambiguities.

Integration — Pre-Scout Activation (IMPORTANT)

When a screenshot is pasted with UI-related intent (fix, update, find, debug), this skill runs BEFORE /scout in any workflow. It narrows the search scope so scout is targeted.

Auto-activation priority: /find-component → /scout → remaining workflow steps

Applies to: bugfix, feature, refactor, fix-ui, verification workflows. Output (matched file paths + component graph) feeds directly into scout/investigate steps.
