metafine_help

A natural-language Q&A skill bundled with MetaFine. Invoke from any Claude Code session as `/metafine_help ` to get a concise answer drawn from this user guide (and, when needed, the live codebase).

What it does

metafine_help is a Claude Code skill that lives at ~/.claude/skills/metafine_help/. It answers usage questions about MetaFine by:

  1. Routing the question to one or more of the 30 user-guide pages via a keyword→page map.
  2. Reading those pages and extracting the relevant 2–5 lines.
  3. Optionally consulting the live codebase on the A100 host when the question demands up-to-date implementation details.
  4. Returning a tight (5–15 line) answer with a concrete command or snippet and a → See: user_guide/<path> citation.

It is strictly read-only — it never writes to disk, never pushes to git, and never modifies the codebase.

Invocation

$ /metafine_help <question>

The argument is a free-form natural-language question in English or Chinese. The agent matches the user's language in its reply. With no argument, it prompts you for the question.

How it routes questions

A 27-row keyword→page map covers every section of the user guide. A question containing "install / pip / conda" routes to Installation; "affordance / closed-set" routes to Affordances; "results.json" routes to Results schema; per-policy questions (ACT, DP3, OpenVLA, π0, StarVLA) route to the matching Policies page; and so on.

If no keyword matches, it falls back to a recursive grep across the user guide directory to find candidate pages.

Examples

$ /metafine_help how do I install metafine
Create a fresh conda env, clone, and pip install -e .. Optional extras [ai] / [dev]. Per-policy stacks install separately. → See: user_guide/getting_started/installation.html
$ /metafine_help 什么是 affordance
Affordance 是 skill 与 asset 之间的桥梁 —— 11 元封闭集词表。Skill 在 @register_skill 声明"需要"哪些 affordance，asset 在 capabilities.json 声明各 part"提供"哪些，闭集查表完成匹配。→ See: user_guide/concepts/affordances.html
$ /metafine_help what's in results.json
Three top-level keys + meta: understanding (per_stage_success + overall), perception (per-axis AUSC + curve_points), behavior (jerk_rms / vel_var / path_length_ratio). → See: user_guide/evaluation/results_schema.html

Limits

  • Read-only. Never writes, never pushes. If you want it to create a new skill or task graph, use metafine_add instead.
  • Debug questions need details. "Why is X failing?" — the agent will ask for the exact error message and the command you ran before triaging.
  • Inventions out. If a CLI flag or API symbol isn't in the user guide and a quick grep doesn't confirm it, the agent says so rather than fabricating one.
  • Scope-bounded. Questions outside the MetaFine platform (general Python, unrelated frameworks) are politely declined.
