FigCC AGENTS.md

A set of project instructions for FigCC, a Figma-connected application that links a Figma plugin with coding agents. It documents the system structure, compatibility requirements, security rules, and storage boundaries.

In plain words
What is it for?
Implementing or reviewing changes to FigCC's interface, Figma integration, bridge server, authentication, agent sessions, and tool routing.
Why use it?
It helps developers modify the project without breaking its connection between Figma, the bridge service, and the coding agents.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

FigCC 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 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.

This file contains repository-wide instructions for coding agents working on FigCC.

Project identity

  • Product name: FigCC.
  • Compatibility package/service identifiers remain figcodex, FIGCODEX_*, and com.figcodex.bridge.
  • FigCC is a derivative of PavelLaptev/FigClaw, used under the MIT License.
  • Preserve LICENSE, NOTICE.md, the upstream copyright line, and the explicit FigClaw attribution in both READMEs.
  • This is an independent community project. Do not imply official affiliation with Figma, Anthropic, or OpenAI.

Runtime architecture

                                      ┌→ codex app-server
Figma iframe UI → authenticated bridge┤
       ↑ tool calls and results ↓      └→ Claude Code Agent SDK
Figma plugin sandbox → open Figma document
  • src/UI.svelte owns the iframe, WebSocket client, provider-scoped conversation state, streamed events, and tool-call routing.
  • src/code.ts owns Figma APIs, client storage, selection snapshots, downloads, and tool execution.
  • bridge/server.js owns pairing authentication, provider dispatch, Codex threads, Claude sessions, attachments, skills, and tool routing.
  • bridge/codex-app-server.js is the JSON-RPC stdio adapter.
  • bridge/claude-provider.js is the Claude Code Agent SDK adapter and in-process FigCC MCP server.
  • bridge/dynamic-tool-reviewer.js performs the independent fail-closed review for side-effecting FigCC tools.
  • bridge/skill-store.js owns canonical filesystem skill packages under skills/<name>/SKILL.md.
  • bridge/workspace-store.js owns the authenticated native folder selection and persisted project root; bridge/linked-skill-store.js overlays that project's live skills/ packages on the bundled set.
  • src/tools.ts is the dynamic-tool schema source of truth.
  • Do not replace the App Server flow with one codex exec subprocess per prompt; that breaks the in-turn client tool handshake and native thread resume.
  • A chat belongs to exactly one provider. Switching Codex/Claude starts a new empty chat; History restores the chat's recorded provider and only its native thread/session ID. Never import transcript text across providers.

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.
