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 | $0.00372 | $0.00372 |
| Opus 5.5 | $0.00149 | $0.00149 |
| Sonnet 5.5 | $0.00074 | $0.00074 |
| Haiku 4.5 | $0.00037 | $0.00037 |
Grade A, and why
figma-tunnel AGENTS.md 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 2mo 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
Repository guidance
Purpose
This project exposes the currently open Figma document through a small HTTP API. Agents receive one secret share URL, read its llms.txt, and use GET and POST requests.
Architecture
Agent → HTTP API (:8765) → loopback relay (:3055) → Figma API Plugin
src/api/server.mjsowns all public routes, access control, idempotency, live documentation, and local plugin-management routes.src/relay/server.jsis an internal Bun WebSocket relay bound to127.0.0.1.src/plugin/runs inside Figma and executes the command dispatcher incode.js.scripts/contains the Windows bootstrap and service controllers.start.cmdis the only user-facing start command on Windows.
Development checks
node --check .\src\api\server.mjs
node --check .\src\api\health.mjs
node --check .\src\relay\server.js
.\start.cmd
There is no build step. The plugin JavaScript and HTML are runtime artifacts and must remain directly executable by Figma.
Rules
- Keep the public interface HTTP-only.
- Keep
/local/control/*loopback-only and inaccessible through Cloudflare. - Keep the relay loopback-only; never expose port
3055. - Read operations work in both access modes. Write operations require write mode and
Idempotency-Key. - Preserve stable JSON error bodies and the generated
llms.txt/OpenAPI descriptions when routes change. - Error responses must link to the nearest valid documentation scope: service, share, or individual route/operation.
- Preserve progress updates for long plugin work.
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.
