UnityFigmaMCP: Skill for Claude Code

.claude/skills/setup-project/SKILL.md

setup-project is a skill for Claude Code from chav0/UnityFigmaMCP. It costs 131 tokens per session (1,219 once invoked), scanned A, original, MIT.

A diagnostic workflow for checking a Unity–Figma bridge: the connection between Figma, an MCP sidecar server, and the Unity Editor. It checks the Figma access token, server setup, Unity connection, and asset configuration.

In plain words
What is it for?
Use it when setting up the project, checking whether it is ready, or diagnosing problems with Figma exports and Unity asset workflows.
Why use it?
These separate connections can fail in ways that look similar, so checking them in order identifies which layer is blocking work. The resulting status report gives the next action to take.

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

setup-project 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.

Setup Project — UnityFigmaMCP Environment Check

This skill runs a diagnostic sequence to verify that all parts of the UnityFigmaMCP bridge are properly configured and connected. It checks each layer of the stack and produces a clear status report with actionable next steps.

Why this matters

UnityFigmaMCP has three independent systems that need to be working together: the Figma API (token + network), the MCP sidecar server, and the Unity Editor plugin connected via SignalR. A problem in any layer blocks the entire workflow, and the symptoms can be confusing — so a structured check saves time.

Diagnostic sequence

Run these checks in order. Each step depends on the previous one succeeding, but continue through all steps even if some fail — the user needs the full picture.

Step 1 — Server, Figma token and Unity connection

Call status. One response covers three things:

  • figma.tokenConfigured / figma.tokenValid — whether FIGMA_ACCESS_TOKEN is set and actually works. tokenValid is true only after a real API call succeeded, so it catches expired and revoked tokens, not just missing ones. figma.user shows who it belongs to.
  • unity.editorConnected — whether a Unity Editor is attached to the SignalR hub, plus unity.hubUrl for the address the Editor plugin connects to.
  • protocolVersion and a hint naming the next concrete action when something is off.

If ready is true, both halves work. Otherwise note what failed and continue — the remaining checks are still informative.

Step 2 — Unity Editor round-trip

Call unity_get_pipelines.

status already reported whether an Editor is registered on the hub, but this is the first call that actually travels the full path — MCP → server → SignalR → Unity Editor and back — and returns data the Editor had to produce. A connected-but-wedged Editor (blocked on a modal dialog, mid-compile) shows up here and not in status.

Step 3 — Pipeline configuration

From the unity_get_pipelines response, check:

  • Are there any pipelines configured?
  • List each pipeline's ID and steps

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.
