AC mcp-server-dev

Skill for developing MCP servers for the LocalCowork project. Use this whenever building a new MCP server, adding tools to an existing server, debugging MCP communication issues, or implementing any tool from the PRD tool registry. MANDATORY TRIGGERS: "build the filesystem server", "add a tool to the document server", "implement the OCR MCP server", "MCP server", "tool implementation", or any mention of a specific server name (filesystem, document, ocr, knowledge, meeting, security, calendar, email, task, data, audit, clipboard, system). Also trigger when user says "implement UC-" since use cases require MCP tools.

How to improve

    For the model run — optional
    • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
    • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

    Process rating: all ten parameters 63/100

    • 0Result and completion. Does not say what the result is
    • 0Failures and branches. Linear process with no failure handling
    • 30Running it twice. 6 mutating operations with no state check
    • 60Tools and files. Uses tools (python) that frontmatter does not declare
    • 70Inputs and preconditions. Inputs and preconditions are listed
    • 100Steps. 31 steps
    • 100When it triggers. States when to use and when not to
    • 100Consistency. Name and required fields are in place
    • 100Execution cost. Instruction body is 1399 tokens
    • 100Progress reporting. Reports progress
    • low The response is described with custom markup (6 tags): a typed call is more reliable

    Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
