implement

A command for implementing a feature or fix in an MCP server project. MCP is a standard way for an AI agent to connect to tools and data.

In plain words
What is it for?
Use it when changing the Figma Console MCP server, including adding tools or fixing behavior. It specifies TypeScript, Zod validation, Puppeteer, Jest tests, Biome formatting, and README updates.
Why use it?
It gives implementation work a defined structure covering validation, browser automation, code quality, tests, coverage, and documentation.

Command for Claude Code

Install

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.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 324 The whole file, excluding the scripts and references it only reads on demand.

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

implement 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 yesterday.

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

Implement Command

Implement a feature or fix using best practices for this MCP server project.

Instructions

When implementing features for the Figma Console MCP server:

  1. Use MCP SDK Patterns

    • Follow Model Context Protocol TypeScript SDK conventions
    • Use McpServer from @modelcontextprotocol/sdk/server/mcp.js
    • Use Zod for input schema validation
    • Return proper content structures: { content: [{ type: "text", text: "..." }] }
  2. Follow Architecture

    • Maintain separation of concerns (Server → Tools → Managers)
    • Use Puppeteer for browser automation
    • Use Chrome DevTools Protocol for console monitoring
    • Implement intelligent log truncation (from AgentDesk patterns)
  3. Code Quality

    • Write TypeScript with strict mode
    • Add JSDoc comments for public APIs
    • Follow existing code style (Biome)
    • Write tests for new features (Jest)
  4. Code Style

    • Use Biome for formatting and linting
    • Run npm run format and npm run lint:fix
  5. Testing

    • Unit tests for business logic
    • Integration tests for tool handlers
    • Maintain 70%+ code coverage
  6. Documentation

    • Update README.md if adding new tools
    • Add inline comments for complex logic

Example Usage

/sc:implement Add error categorization to console logs

This will activate the implementation agent with context about the MCP server project.

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.

implement is a command published in the GitHub repository southleft/figma-console-mcp (2,220 stars, last pushed 15d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 324 tokens. 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 2026-08-30.
