Scan Design System

Codex compatibility note:

>

- Invoke repository skills with $skill-name in Codex; this mirrored copy rewrites legacy Claude /skill-name references.

- Task tracker mandate: BEFORE executing any workflow or skill step, create/update task tracking for all steps and keep it synchronized as progress changes.

- User-question prompts mean to ask the user directly in Codex.

- Ignore Claude-specific mode-switch instructions when they appear.

- Strict execution contract: when a user explicitly invokes a skill, execute that skill protocol as written.

- Subagent authorization: when a skill is user-invoked or AI-detected and its protocol requires subagents, that skill activation authorizes use of the required spawn_agent subagent(s) for that task.

- Do not skip, reorder, or merge protocol steps unless the user explicitly approves the deviation first.

- For workflow skills, execute each listed child-skill step explicitly and report step-by-step evidence.

- If a required step/tool cannot run in this environment, stop and ask the user before adapting.

Codex Project-Reference Loading (No Hooks)

Codex does not receive Claude hook-based doc injection. When coding, planning, debugging, testing, or reviewing, open project docs explicitly using this routing.

Always read:

• docs/project-config.json (project-specific paths, commands, modules, and workflow/test settings)
• docs/project-reference/docs-index-reference.md (routes to the full docs/project-reference/* catalog)
• docs/project-reference/lessons.md (always-on guardrails and anti-patterns)

Situation-based docs:

• Backend/CQRS/API/domain/entity changes: backend-patterns-reference.md, domain-entities-reference.md, project-structure-reference.md
• Frontend/UI/styling/design-system: frontend-patterns-reference.md, scss-styling-guide.md, design-system/README.md
• Spec/test-case planning or TC mapping: feature-docs-reference.md
• Integration test implementation/review: integration-test-reference.md
• E2E test implementation/review: e2e-test-reference.md
• Code review/audit work: code-review-rules.md plus domain docs above based on changed files

Do not read all docs blindly. Start from docs-index-reference.md, then open only relevant files for the task.

<!-- CODEX:PROJECT-REFERENCE-LOADING:END -->

Quick Summary

Goal: Scan project for design system artifacts → populate docs/project-reference/design-system/README.md with overview, app-to-documentation mapping, design token inventory, and component catalog. (read directly when relevant; do not rely on hook-injected conversation text)

Workflow:

1. Classify — Detect design system type and approach before scanning 2. Scan — Parallel sub-agents discover structure, components, tokens 3. Report — Write findings incrementally to report file 4. Generate — Build/update reference doc from report 5. Fresh-Eyes — Round 2 verification validates paths and token values

Key Rules:

• Generic — works with any design system approach
• Discover organization dynamically from file system

MUST ATTENTION detect design system TYPE first — agent emphasis depends on type

• Every reference must point to real files — NEVER fabricate component names or token values

---

Scan Design System

Phase 0: Classify Design System Type

Before any other step, run in parallel:

1. Read docs/project-reference/design-system/README.md

• Detect mode: Init (placeholder) or Sync (populated)
• In Sync mode: extract section list → skip re-scanning well-documented sections

2. Detect design system type:

3. Resolve config-driven paths from docs/project-config.json:

• designSystem.canonicalDoc — single source of truth for new code
• designSystem.tokenFiles — drop-in token files
• Read these names from config — content varies per project; never hardcode them.

4. Check for app-specific design docs in the same directory

Evidence gate: Confidence <60% on design system type → report uncertainty, proceed with Agent 1 (structure) only.

Phase 1: Plan

Create task tracking entries for each sub-agent and each verification step. Do not start Phase 2 without tasks created.

Phase 2: Execute Scan (Parallel Sub-Agents)

Launch 3 general-purpose sub-agents in parallel. Each MUST:

• Write findings incrementally after each category — NEVER batch at end
• Cite file:line for every finding
• Confidence: >80% document; 60-80% note as "observed (unverified)"; <60% omit

All findings → plans/reports/scan-design-system-{YYMMDD}-{HHMM}-report.md

Agent 1: Design System Structure

Think: How is the design system organized? What's the canonical doc? What's the token chain? Which apps have design docs and which don't?

• Glob for docs/project-reference/design-system/** to map all design docs
• Find design token files (CSS custom properties, SCSS variables, JSON tokens)
• Discover Storybook stories (*.stories.ts, *.stories.tsx, *.stories.mdx)
• Find component library entry points (index files, barrel exports)
• Map app-to-design-doc relationships
• Verify canonical doc at {docsPath}/{canonicalDoc} has expected sections. Flag missing sections.
• Verify token files at {docsPath}/{tokenFiles[i]} exist and contain variable declarations. Flag empty/missing.

Agent 2: Component Inventory

Think: What dimensions define a complete component inventory? Consider: Discoverability (can I find it?), Categorization (what type?), Variant coverage (size/color/state?), Accessibility (ARIA/keyboard?), Documentation completeness (JSDoc/README/Storybook?), Icon/asset library coverage.

For each dimension, derive the specific grep/glob patterns from what the project actually uses — do NOT hardcode Angular/React/Vue-specific patterns unless confirmed.

• Find reusable UI components (shared component directories, exported components)
• Find component categories (layout, forms, feedback, navigation, data display)
• Discover component variants (size, color, state variations)
• Find icon sets or asset libraries
• Look for accessibility patterns (ARIA roles, keyboard support)
• Find documentation for individual components

Agent 3: Token & Component Source Discovery

Think: What design tokens actually exist in source code (not just what's documented)? Which are declarations (authoritative) vs usages (derived)?

Source scope (whitelist, not full repo):

• src/**/styles/**/*.{scss,css}, src/**/themes/**/*.{scss,css}, src/**/tokens/**/*.{scss,css}
• src/**/*.scss ONLY when path contains theme, token, palette, design, style-guide, or variables
• Exclude node_modules, dist, .nx, coverage, component-local styles

Discovery rules (declarations only, NOT usages):

• CSS custom properties (declarations): --[a-zA-Z][a-zA-Z0-9_-]*\s*: — capture LHS only, dedupe
• SCSS variable declarations: ^\s*\$[a-zA-Z][a-zA-Z0-9_-]*\s*: — anchor to start-of-line
• Color values used ≥3 times across whitelist (hex, rgb, hsl)
• Spacing scale (declarations): (padding|margin|gap)\s*:\s*[\d.]+(px|rem|em) — extract values, dedupe
• Typography (declarations): (font-family|font-size|font-weight)\s*: — extract RHS, dedupe
• Breakpoints: @media[^{]*\((min|max)-width:\s*[\d.]+(px|em|rem)\) — extract widths, dedupe

Categorise: Colors / Typography / Spacing / Breakpoints / Z-Index / Elevation / Component-prefixes / Other. Persist incrementally — append to report after each category. Quality gate: If a category has <3 unique entries OR >200 entries, log "scope too narrow/broad — manual refinement required".

Phase 3: Analyze & Generate

Read report. Build target sections.

Round 1 (main agent): Build section drafts from report findings.

Round 2 (fresh sub-agent, zero memory): Independently verifies:

• All doc paths exist on filesystem (Glob check — not just "looks right")
• All token values are from actual declarations, not usages or fabricated
• Component names in inventory match actual files (Grep check)
• Gap Analysis section present (what's missing, not just what exists)

Target Sections

Authoring (init mode only)

When init mode detected (canonical doc missing or placeholder):

1. Author `{docsPath}/{canonicalDoc}` from Agent 3 findings:

• Prepend regen marker: <!-- Generated by $scan-design-system on YYYY-MM-DD; refine sections manually -->
• Sections: Foundations, Tokens, Components, Patterns, Accessibility, Adoption Strategy

2. Author each `{docsPath}/{tokenFiles[i]}` from grouped declarations:

• First: REMOVE `PLACEHOLDER_MARKER_SCSS` sentinel before writing real tokens
• .scss: SCSS variable block per category + CSS custom property mirrors in :root {}
• Categories: Colors, Typography, Spacing, Breakpoints, Z-Index, Elevation/Shadow

3. Preserve manual content in sync mode — DO NOT overwrite populated doc/token file

Phase 4: Write & Verify

1. Write updated doc with <!-- Last scanned: YYYY-MM-DD --> at top 2. Surgical update only — preserve unchanged sections 3. Verify config-driven paths: {docsPath}/{canonicalDoc} and every {docsPath}/{tokenFiles[i]} 4. Verify (Glob): ALL component paths in inventory exist — not just 3 5. Verify (Grep): Token names in doc match actual declarations in source 6. Verify: Gap Analysis section present 7. Report: sections updated / unchanged / gaps documented / canonical + token presence

[IMPORTANT] Use task tracking to break ALL work into small tasks BEFORE starting — including tasks per file read. Prevents context loss from long files. Simple tasks: ask user whether to skip.

Prerequisites: MUST ATTENTION READ before executing:

<!-- SYNC:critical-thinking-mindset -->

Critical Thinking Mindset — Every claim needs traced proof, confidence >80% to act.

Anti-hallucination: Never present guess as fact — cite sources, admit uncertainty, self-check output, cross-reference independently. Certainty without evidence = root of all hallucination.

<!-- /SYNC:critical-thinking-mindset -->

<!-- SYNC:scan-and-update-reference-doc -->

Scan & Update Reference Doc — Surgical updates only, NEVER full rewrite.

>

1. Read existing doc first — understand structure and manual annotations

2. Detect mode: Placeholder (headings only) → Init. Has content → Sync.

3. Scan codebase (grep/glob) for current patterns

4. Diff findings vs doc — identify stale sections only

5. Update ONLY diverged sections. Preserve manual annotations.

6. Update metadata (date, version) in frontmatter/header

7. NEVER rewrite entire doc. NEVER remove sections without evidence obsolete.

<!-- SYNC:output-quality-principles -->

Output Quality — Token efficiency without sacrificing quality.

>

1. No inventories/counts — stale instantly

2. No directory trees — use 1-line path conventions

3. No TOCs — AI reads linearly

4. One example per pattern — only if non-obvious

5. Lead with answer, not reasoning

6. Sacrifice grammar for concision in reports

7. Unresolved questions at end

AI Mistake Prevention — Failure modes to avoid:

>

Verify AI-generated content against actual code. AI hallucinates component names/token values. Grep to confirm existence before documenting.

NEVER invent variable values, hex colors, or mixin signatures. Grep to confirm before documenting.

Trace full dependency chain after edits. Always trace full chain.

Surface ambiguity before coding. NEVER pick silently.

Closing Reminders

IMPORTANT MUST ATTENTION break work into small task tracking tasks BEFORE starting IMPORTANT MUST ATTENTION detect design system TYPE in Phase 0 — agent emphasis depends on it IMPORTANT MUST ATTENTION NEVER invent variable values, hex colors, or mixin signatures — Grep to confirm IMPORTANT MUST ATTENTION sub-agents write findings incrementally after each category — NEVER batch at end IMPORTANT MUST ATTENTION Gap Analysis section is mandatory — document what's missing, not just what exists IMPORTANT MUST ATTENTION when Round 1 finds issues, Round 2 fresh-eyes after fixing validates paths and token values. Clean Round 1 ENDS the scan.

Hookless Prompt Protocol Mirror (Auto-Synced)

Source: .claude/hooks/lib/prompt-injections.cjs + .claude/.ck.json

[WORKFLOW-EXECUTION-PROTOCOL] [BLOCKING] Workflow Execution Protocol — MANDATORY IMPORTANT MUST CRITICAL. Do not skip for any reason.

Generic portability boundary: Reusable skills and protocol text stay project-neutral; project-specific conventions are discovered from docs/project-config.json and docs/project-reference/. Apply shared AI-SDD from shared/sdd-artifact-contract.md. Read docs/project-config.json and docs/project-reference/docs-index-reference.md, then open the project reference docs named there. Any supported AI tool may execute when this shared context and local docs are available.

1. DETECT: Match prompt against workflow catalog 2. ANALYZE: Find best-match workflow AND evaluate if a custom step combination would fit better 3. ASK (REQUIRED FORMAT): Use a direct user question with this structure unless the user explicitly invoked a workflow/skill and the local protocol treats explicit invocation as confirmation:

• Question: "Which workflow do you want to activate?"
• Option 1: "Activate [BestMatch Workflow] (Recommended)"
• Option 2: "Activate custom workflow: [step1 → step2 → ...]" (include one-line rationale)

4. ACTIVATE (if confirmed): Call $workflow-start <workflowId> for standard; sequence custom steps manually 5. CREATE TASKS: task tracking for ALL workflow steps 6. EXECUTE: Follow each step in sequence [CRITICAL-THINKING-MINDSET] Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act. Anti-hallucination principle: Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination. AI Attention principle (Primacy-Recency): Put the 3 most critical rules at both top and bottom of long prompts/protocols so instruction adherence survives long context windows. Goal-driven execution: Define success criteria first, loop until verified, and stop only when observable checks pass. Tests verify intent: Tests must protect business rules/invariants and fail when the protected intent breaks, not only mirror current behavior.

[LESSON-LEARNED-REMINDER] [BLOCKING] Task Planning & Continuous Improvement — MANDATORY. Do not skip.

Break work into small tasks (task tracking) before starting. Add final task: "Analyze AI mistakes & lessons learned".

Extract lessons — ROOT CAUSE ONLY, not symptom fixes:

1. Name the FAILURE MODE (reasoning/assumption failure), not symptom — "assumed API existed without reading source" not "used wrong enum value". 2. Generality test: does this failure mode apply to ≥3 contexts/codebases? If not, abstract one level up. 3. Write as a universal rule — strip project-specific names/paths/classes. Useful on any codebase. 4. Consolidate: multiple mistakes sharing one failure mode → ONE lesson. 5. Recurrence gate: "Would this recur in future session WITHOUT this reminder?" — No → skip $learn. 6. Auto-fix gate: "Could $code-review/$code-simplifier/$security/$lint catch this?" — Yes → improve review skill instead. 7. BOTH gates pass → ask user to run $learn. [TASK-PLANNING] [MANDATORY] BEFORE executing any workflow or skill step, create/update task tracking for all planned steps, then keep it synchronized as each step starts/completes.
