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 | $0.00044 | $0.00462 |
| Opus 5.5 | $0.00018 | $0.00185 |
| Sonnet 5.5 | $0.00009 | $0.00092 |
| Haiku 4.5 | $0.00004 | $0.00046 |
Grade A, and why
figma-create-new-file 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.
What it actually says
Create a new file in Figma
Steps to create a new Figma Design, FigJam, or Slides file using the create_new_file MCP tool.
Step 1: Resolve the planKey and editorType
Use the planKey the user provided or selected for this task. Otherwise, call whoami and inspect the returned plans.
- No plans: inform the user that file creation cannot proceed.
- One plan: use its
keyasplanKey. - Multiple plans: show the available plans, ask the user to select one and then use that plan's
keyasplanKey.
Infer editorType from the requested file type by choosing from the tool's advertised input enum. If unclear, ask the user to specify the file type.
Step 2: Call create_new_file
Call the create_new_file tool with all three required arguments:
fileName: Required. Choose a concise name if the user does not provide one.planKey: Required. Use theplanKeyresolved in Step 1.editorType: Required. Use theeditorTypeselected in Step 1.projectId: Optional. Set it to create the file in a specific project.
{
"fileName": "Quarterly planning",
"planKey": "team::1234567890",
"editorType": "design"
}
- Use the
file_keyfrom thecreate_new_filetool response for subsequent tool calls likeuse_figma.
Step 3: (Slides only) Handle the empty grid
A new Slides file contains no slides: figma.getSlideGrid() returns []. Before reading properties such as theme tokens from a slide, call figma.createSlide() or handle the empty case. The first createSlide() call automatically creates row 0 and inserts the slide.
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-create-new-file is a skill published in the GitHub repository anomalyco/opencode (213,922 stars, last pushed today), licensed MIT. It adds 44 tokens to every session and 462 once invoked, about $0.0002 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.
