Sync

Purpose

Report-only drift check between this plugin's vendored dometrain-grounding baseline (vendor/SKILL.md) and Dometrain's current upstream skill content (github.com/Dometrain/mcp, skills/dometrain-grounding/SKILL.md). There is one upstream dependency and no CLI to upgrade, only vendored prose to diff.

Consumer vs maintainer role split: this skill is disable-model-invocation: true, so it is reachable only by a human's explicit /dometrain:sync invocation, never by the model on its own initiative. check (the only action) is report-only. The --refresh-baseline flag is not skill-exposed; context/update.md documents it for a maintainer to type as a raw bash command in a working clone.

check (report-only, the only action)

Run:

bash "${CLAUDE_PLUGIN_ROOT}/skills/sync/scripts/update.sh"

The script:

1. Fetches Dometrain's current skills/dometrain-grounding/SKILL.md from raw.githubusercontent.com.
2. Diffs it against vendor/SKILL.md (stripping the vendored file's own attribution comment first, since upstream never carries it).
3. Reports "No drift detected" or shows the diff for manual review.

Never writes to vendor/SKILL.md or grounding/SKILL.md. Direct the user to context/update.md for the maintainer-only integration protocol.

Output

Report the script's exit code and its stdout verbatim (or a short summary if long): drift present or absent, and when present, point to context/update.md for the next step.

Boundaries

• Never model-invocable. This skill exists so a maintainer can check drift explicitly, not so the model can decide on its own that a check is warranted.
• Never runs --refresh-baseline. That overwrites the vendor snapshot and is restricted to a maintainer typing the raw command directly in a working clone.
• Never edits grounding/SKILL.md. Integration is a human decision, documented in context/update.md.
