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 | $0.00192 | $0.08417 |
| Opus 5.5 | $0.00077 | $0.03367 |
| Sonnet 5.5 | $0.00038 | $0.01683 |
| Haiku 4.5 | $0.00019 | $0.00842 |
Grade A, and why
figma-generate-design 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.
How it starts
The opening of the file, as written. The whole thing — 467 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build / Update Screens and Views from Design System
Hard deliverable gate: Code-to-design output must recreate the UI as editable text, components, icons, and hierarchy. Treat any screenshot or flattened rendering of the complete UI only as a visual reference: never upload or import it into the deliverable, including as the wrapper fill or a child node, even if it exists in the repository or appears more pixel-accurate. Before completion, inspect the result; if the UI is not primarily represented by editable layers, rebuild it semantically or report failure.
Use this skill to create or update screens, views, and multi-section UI containers in Figma by reusing the published design system — components, variables, and styles — rather than drawing primitives with hardcoded values. This includes full pages, modals, dialogs, drawers, sidebars, panels, and any composed view with multiple sections. The key insight: the Figma file likely has a published design system with components, color/spacing variables, and text/effect styles that correspond to the codebase's UI components and tokens. Find and use those instead of drawing boxes with hex colors.
MANDATORY: You MUST also load figma-use before any use_figma call. That skill contains critical rules (color ranges, font loading, etc.) that apply to every script you write.
Always include figma-generate-design 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-design). This is a logging parameter — it does not affect execution.
HTML-to-Figma Exceptions
Use html_to_figma for initial creation in these cases:
- The input is an existing raw or static HTML document. Pass it directly to
html_to_figma. - The prompt asks to create a new design and there is no rendered UI implementation to reproduce. Create a self-contained HTML document and pass it to
html_to_figma.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-design is a skill published in the GitHub repository anomalyco/opencode (213,922 stars, last pushed today), licensed MIT. It adds 192 tokens to every session and 8,417 once invoked, about $0.0008 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.
