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 5.1 | $0.00072 | $0.00333 |
| Opus 5.5 | $0.00029 | $0.00133 |
| Sonnet 5.5 | $0.00014 | $0.00067 |
| Haiku 4.5 | $0.00007 | $0.00033 |
Grade A, and why
system-overview 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 today.
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
System Overview
Get a comprehensive overview of the design system in a Figma file.
Process
-
Identify the Figma file. The user should provide a file key or URL.
-
Fetch the design system summary:
- Call
figma_get_design_system_summaryto get counts and page structure - Call
figma_get_stylesto list all published styles - Call
figma_get_componentsto list all published components - Call
figma_get_variableswithexportFormat: "json"to get token structure
- Call
-
Compile the overview:
- File info: Name, last modified, page count
- Components: Total count, listed by name with descriptions
- Styles: Counts by type (fill, text, effect, grid), listed with names
- Tokens: Collection count, variable count by type (color, float, string, boolean), mode names
- Structure: Page names and what each page contains
-
Present the overview to the user in a clear, structured format.
Output
A structured design system overview presented to the user, useful for onboarding or auditing the design system state.
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.

system-overview is a skill published in the GitHub repository bromso/metapowers (2 stars, last pushed today), licensed MIT. It adds 72 tokens to every session and 333 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-21.

motion-art-direction
Use when a film needs a look before any scene code — ads, launch teasers, brand films, type-led films with no screenshots, or whenever a draft looks flat (white ground, small tiles, centered text, fades, slow camera drift, logo opener).

Use when adding or reviewing motion on an already-settled layout or component — never to hide or compensate for an unfinished one.
