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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00026 | $0.00352 |
| Opus 5 | $0.00013 | $0.00176 |
| Sonnet 5 | $0.00005 | $0.00070 |
| Haiku 4.5 | $0.00003 | $0.00035 |
Grade A, and why
design-component 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 yesterday.
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.
What it actually says
/design:component — Single Component (COMPONENT scope)
Generate one UI component using existing design tokens.
Complete documentation: skills/design-web/SKILL.md (or skills/design-webapp/SKILL.md for an app-specific pattern like a data table or command palette).
Usage
/design:component pricing card with 3 tiers
/design:component testimonial carousel
/design:component data table with sorting
Prerequisites
design-system.md must exist at project root. If missing, use /design instead.
Workflow
- Read
design-system.md— this is the single source of truth for tokens. - No inspiration browsing (COMPONENT scope skips it per
design-method's routing table). Optionally searchskills/design-web/references/21st-dev.mdorshadcn.mdfor pattern inspiration. - Generate the component directly as HTML/CSS from
design-system.mdtokens, followingskills/design-web/references/component-variants-ref.mdfor size/state/color variants. - Read
skills/design-motion/SKILL.md— gate micro-interactions; mandatory hover/focus/disabled states regardless. - Read
skills/design-review/SKILL.md, component-scoped: contrast, forbidden fonts, OKLCH-only, all states present, light+dark screenshot of the component in isolation.
Forbidden
Creating a new design-system.md. Inspiration browsing (use the search tools above instead). Skipping light+dark validation.
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-component is a command published in the GitHub repository fusengine/agents (25 stars, last pushed 1mo ago), licensed MIT. It adds 26 tokens to every session and 352 once invoked, about $0.0001 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 2026-09-03.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
