Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00035 | $0.11029 |
| Opus 5 | $0.00017 | $0.05514 |
| Sonnet 5 | $0.00007 | $0.02206 |
| Haiku 4.5 | $0.00003 | $0.01103 |
Grade A, and why
design-system-governance scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Design System Governance
Skill Usage Announcement
MANDATORY: When using this skill, announce it at the start with:
🔧 Using Skill: design-system-governance | [brief purpose based on context]
Example:
🔧 Using Skill: design-system-governance | Auditing design token drift between Figma and codebase
This creates an audit trail showing which skills were applied during the session.
Overview
Use this skill to detect and track design token drift between Figma design systems and code implementations. This is a REPORT-ONLY skill that identifies inconsistencies and creates wrangler issues for resolution, but does not auto-fix tokens.
When to Use This Skill
Use this skill when:
- Periodic governance checks - Regular audits (weekly/monthly) to ensure design-code alignment
- After Figma updates - Design team publishes new token values in Figma
- Before releases - Pre-deployment verification of design token consistency
- Onboarding new projects - Initial baseline assessment of design system health
- Design system migrations - Tracking progress during token standardization efforts
- Post-implementation review - Verifying developers used correct design tokens
Do NOT use this skill for:
- One-off component styling (use regular development workflow)
- Custom/bespoke designs that intentionally deviate from the system
- Projects without established design systems
Prerequisites
Before running governance checks, ensure:
- Figma design system exists with published styles/variables
- Code tokens are exported in at least one format (CSS variables, Tailwind config, design tokens JSON)
- Figma MCP server is configured with access to the design file
- Token naming conventions are documented (if custom normalization needed)
- Wrangler MCP is initialized for issue tracking
Workflow
1. Extract Design Tokens from Figma
↓
2. Parse Code Token Sources
↓
3. Normalize Token Names
↓
4. Compare & Detect Drift
↓
5. Classify Drift Severity
↓
6. Generate Reconciliation Recommendations
↓
7. Create Wrangler Issues (one per drift category)
↓
8. Update Governance Metadata
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

design-system-governance is a skill published in the GitHub repository bacchus-labs/wrangler (4 stars, last pushed 6mo ago), licensed MIT. It adds 35 tokens to every session and 11,029 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
