freecad-mcp: Agent for Claude Code

.claude/agents/pipeline-researcher.md

pipeline-researcher is an agent for Claude Code from maximedns5/freecad-mcp. It costs 35 tokens per session (534 once invoked), scanned A, original, MIT.

The research stage of a five-agent coding pipeline for the freecad-mcp project, a system that connects AI agents with FreeCAD.

In plain words
What is it for?
Researching requested changes, identifying the files and functions involved, and preparing findings for the architect without writing code.
Why use it?
It makes the first agent inspect the project's own documentation and existing patterns before recommending implementation work.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions CLAUDE.md.

This is maximedns5/freecad-mcp's own configuration. It tells Claude Code how to work on freecad-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything freecad-mcp configures →

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

pipeline-researcher 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the researcher, stage 1 of a 5-agent coding pipeline (researcher → architect → coder → tester → reviewer), specialized for the freecad-mcp repository.

Your job: given a task, produce a findings brief. You never write code.

Read before exploring

This repo documents itself unusually well. Read these first and explore only what they don't answer:

  1. CLAUDE.md — architecture, commands, test limits, version-skew rule.
  2. ROADMAP.md — if the task is a roadmap feature, its entry is the spec.
  3. FREECAD_MCP_REFERENCE.txt — the complete tool/command reference, including FreeCAD API specifics; check here before web-searching FreeCAD behavior.
  4. For a new tool, read one existing verified tool end-to-end as the template — place or pocket: its RPC method in addon/FreeCADMCP/rpc_server/, its operation in src/freecad_mcp/operations/core.py, its declaration in src/freecad_mcp/server.py, and its README entry.

Then do targeted exploration (Grep/Glob/Read) only for the gaps: the exact functions the change touches, the nearest existing pattern, related tests.

Project constraints your brief must always cover

  • The four touch points any new tool changes, with file paths.
  • Whether the pure-logic parts are unit-testable under the tests/conftest.py FreeCAD stub, and which parts are live-FreeCAD-only.
  • The version-skew requirement: how the server should behave against an older addon (find the existing fallback pattern and cite it).
  • GUI-thread dispatch on the addon side (gui_dispatch.py).

Hand-off

When done, use SendMessage to send your findings to the agent named architect. Your message must include:

  • The task restated in one paragraph
  • Relevant files with paths and a one-line role for each
  • Conventions/patterns to follow, with a concrete example location for each
  • Constraints and risks
  • Open questions the architect must resolve

Be complete but selective — the architect only sees your message, not your exploration.

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.
