OpenCode is an open-source AI coding agent that helps developers work on software projects. It includes agents for full-access development, read-only exploration and planning, plus a general subagent for complex searches and multistep tasks; the catalogue add-ons extend its workflows.
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 | $0.00146 | $0.05314 |
| Opus 5.5 | $0.00058 | $0.02126 |
| Sonnet 5.5 | $0.00029 | $0.01063 |
| Haiku 4.5 | $0.00015 | $0.00531 |
Grade A, and why
figma-generate-library 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 2d 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 Builder — Figma MCP Skill
Build professional-grade design-system assets in Figma that match code. Scale the workflow to the requested deliverable: a token set, one component, a complete library, or a targeted reconciliation. Run the selected path in coherent, safely retryable construction phases with evidence-based validation.
Prerequisites: The figma-use skill MUST also be loaded for every use_figma call. It provides Plugin API syntax rules (return pattern, page reset, ID return, font loading, color range). This skill provides design system domain knowledge and workflow orchestration.
Always include figma-generate-library in the comma-separated skillNames parameter when calling use_figma as part of this skill. If this skill was loaded via an MCP resource, you MUST prefix the name with resource: (e.g. resource:figma-generate-library). This is a logging parameter — it does not affect execution.
1. Scope and Completion Contract
Before the first mutation, choose one primary scope from the user's request and record its included deliverables and acceptance checks. Do not silently promote a narrower request into a full-library project.
| Requested scope | Required work | Excluded unless requested or necessary |
|---|---|---|
| Tokens / foundations only | Requested variables, modes, scopes, code syntax, styles, and any requested specimen sheet | Components, component pages, Code Connect, full-library navigation |
| Single component or family | Inspect and reuse compatible foundations; create only missing tokens the component requires; build requested variants/properties/bindings; validate the component | Unrelated foundations, other components, full file skeleton, broad documentation or audits |
| Full library / design system | Discovery, foundations, file structure, requested component inventory, documentation, integration, and final QA | Work outside the agreed v1 inventory |
| Reconciliation / update | Diff code and Figma, then update only affected tokens, styles, components, docs, and dependents | Rebuilding valid assets or expanding the library |
What ships with it

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.

figma-generate-library is a skill published in the GitHub repository anomalyco/opencode (213,922 stars, last pushed today), licensed MIT. It adds 146 tokens to every session and 5,314 once invoked, about $0.0006 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 2026-10-14.
