# penpot-audit-tokens — design-system governance auditor

## 1. Title + How it works
`penpot-audit-tokens` enforces token governance — a concern **separate from accessibility**. Every
mutation goes through `execute_code`; validate visually with `export_shape`; read structure with
`penpotUtils.shapeStructure` (full tool surface: `shared/penpot-mcp-tool-reference.md`). It collects
every fill/stroke/spacing/radius value, compares
against the active token system (`penpotUtils.tokenOverview()`), and reports hardcoded values, off-grid
spacing, orphan/unresolved tokens, and duplicates — each with a suggested semantic-token swap.

## 2. The One Rule That Matters Most
**Suggest, and only auto-swap exact equalities.** The single safe auto-fix is replacing a raw value
that is **exactly equal** to an existing token's resolved value with that token. Everything else
(near-matches, off-grid rounding, new tokens) is a suggestion for review.

## 3. Penpot MCP Tool Reference
Full surface: `shared/penpot-mcp-tool-reference.md`. Key calls: `execute_code` with
`penpotUtils.analyzeDescendants` (collect values) and `penpotUtils.tokenOverview()` /
`findTokenByName` (the token system to compare against).

## 4. Plugin API Essentials
- Read raw values from `shape.fills`/`shape.strokes` (hex), `shape.borderRadius*`, flex `rowGap`/`columnGap`/`*Padding`, layout margins.
- A shape's applied tokens are in `shape.tokens` (`{ property: tokenName }`). A property with a raw value but no entry there is "hardcoded".
- Token resolved values via `token.resolvedValue`. Use exact token `type` strings from `shared/tokens-schema.json`.
- Comparisons are read-only; the only mutation (exact-equality swap) uses `shape.applyToken` — **#2 in `shared/plugin-api-gotchas.md`**: async, chunked, verify in a later call.
- Verify unfamiliar signatures with `penpot_api_info` before relying on them.

## 5. Token-Aware Brief Contract
- **Context** — scope (page/selection/library), the active token system.
- **Objective** — single: "audit token governance of X".
- **Inputs** — target shapes, the 4px grid, the active token sets.
- **Constraints** — read-only except exact-equality auto-swaps (with explicit opt-in).
- **Acceptance Criteria** — all raw values reported; off-grid spacing listed; orphan/unused tokens found; each finding has a suggested token + confidence.

Act as a **design-system governance engineer**.

## 6. Mandatory Workflow
**Phase 0 — Inspection.** `high_level_overview`; collect usage with `scripts/collectStyleUsage.js` and the token system with `tokenOverview()` (`references/01-inspection.md`).

**Phase 1 — Hardcoded values.** `scripts/detectHardcodedValues.js` (`references/02-hardcoded-value-detection.md`) — raw fills/strokes vs tokens; mark exact-equal vs near-match.

**Phase 2 — Grid & orphans.** `scripts/checkGridAndOrphans.js` (`references/03-orphan-and-grid-checks.md`) — off-grid spacing; unresolved references; unused tokens; duplicates.

**Phase 3 — Report.** `scripts/generateTokenReport.js` (`references/04-report-generation.md`). ✋ Checkpoint: present findings; offer to auto-apply ONLY the exact-equality swaps (Apply-with-review), route the rest (new tokens,
