coffee-roaster-mcp: Skill for Claude Code

.claude/skills/mock-roast/SKILL.md

mock-roast is a skill for Claude Code from syamaner/coffee-roaster-mcp. It costs 22 tokens per session (392 once invoked), scanned A, original, Apache-2.0.

A local testing workflow for RoastPilot, a coffee-roasting control service, that uses a simulated roaster instead of real hardware. It checks the service startup and its MCP tool flow without microphones, downloaded models, or network access.

In plain words
What is it for?
Use it to check the default settings, show the command-line help and version, start the MCP server, and exercise the first roast-session tools on the simulated roaster.
Why use it?
It lets developers test the early software path before the physical roaster and speech-detection parts are ready. This avoids needing hardware or large model files just to check that the service starts and responds.

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

mock-roast 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 7d 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.

What it actually says

Mock Roast - RoastPilot

Use this skill for the mock-first local workflow. Root AGENTS.md is the current gate and tool authority; this skill is hardware-free planning/audit guidance, not an alternative runtime or delivery contract.

Current Scope

  • This workflow validates the current mock-safe bootstrap path without roaster hardware, microphone access, model download, or network. For full operator setup details, use docs/install-and-hardware-setup.md.

Current Validation

Run from the repository root:

python -c "import os, tempfile; from coffee_roaster_mcp.config import load_config; tmp = tempfile.TemporaryDirectory(); os.chdir(tmp.name); c = load_config(environ={}); print(c.roaster.driver, c.first_crack.mode, c.first_crack.precision); tmp.cleanup()"
coffee-roaster-mcp --help
coffee-roaster-mcp --version

Expected bootstrap output:

mock disabled int8

What This Confirms

  • The default roaster driver stays on mock.
  • First-crack detection stays disabled by default.
  • Default precision stays int8.
  • Local bootstrap does not require roaster hardware, microphone access, or model download.
  • The installed CLI can report its help and version without hardware.

Do Not Claim Here

  • Mock checks never establish hardware readiness or replace human-owned hardware validation.
  • Do not add model download, model export, or Hugging Face sync steps here. Those stay in coffee-first-crack-detection.

For current MCP tool and mock-roast behaviour, consult root AGENTS.md, the active state authority, and the ratified contract rather than maintaining a second tool inventory here.

Changes

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.
