Repo

/up-docs:repo

Update the active repo's docs via the up-docs-propagate-repo sub-agent (Sonnet).

Workflow

0. Pre-flight: Dirty-tree guard

Before doing anything else, check for uncommitted changes (staged, unstaged, or untracked — --porcelain reports all three, and the STOP applies to all three):

git status --porcelain

If the output is non-empty, STOP immediately:

• Emit the list of dirty files to the user.
• Refuse with: "Uncommitted changes detected — stash or commit them before running /up-docs:repo to prevent data loss."
• Do NOT dispatch the sub-agent. Do NOT read session context. Do NOT proceed to Step 1.

If the output is empty, continue.

Capture commit baseline (for the Step 5 commit offer): BEFORE propagation, snapshot the repo's dirty set into a freshly mktemp'd file (NOT a fixed path — concurrent runs would collide, CR-004) and remember the generated path: BASELINE_REPO=$(mktemp); bash ${CLAUDE_PLUGIN_ROOT}/scripts/commit-candidates.sh snapshot . > "$BASELINE_REPO". Thread $BASELINE_REPO to Step 5 — do not hardcode the baseline filename there.

1. Gather Session Context

First, verify Python 3 is available — all helper scripts depend on it:

command -v python3 >/dev/null 2>&1 || { echo "ERROR: python3 not found in PATH — install python3 and retry."; exit 1; }
bash ${CLAUDE_PLUGIN_ROOT}/scripts/context-gather.sh

Combine with conversation history.

2. Build the Session-Change Summary

Read ${CLAUDE_PLUGIN_ROOT}/templates/session-change-summary.md for the canonical format. Produce a concrete summary following that template — name exact keys/values/paths, not vague "updated config" language.

3. Dispatch up-docs-propagate-repo

Invoke the sub-agent via the Agent tool with subagent_type: "up-docs:up-docs-propagate-repo" (the up-docs: prefix is required — plugin-defined agents are only addressable through their plugin namespace). The prompt has the session-change summary at the stable front, followed by any repo-specific context (CLAUDE.md ## Documentation section if present).

4. Pass the Sub-agent's Output Through

The sub-agent returns a markdown table conforming to templates/summary-report.md single-layer "Repo" format. Emit it as the skill's final output. Do not make your own edits — the sub-agent did the work.

If the sub-agent fails entirely (MCP timeout, spawn error), report a single-row table noting the failure with a one-sentence reason.

5. Post-Propagation Steps (stale-candidate review + handoff brief)

Read ${CLAUDE_PLUGIN_ROOT}/templates/post-propagation-steps.md and follow all three procedures against the sub-agent's output:

• Stale File Candidate Review — if the output has a ## Stale File Candidates section, present it via AskUserQuestion (multiSelect) and git rm only user-approved paths. Skip silently if none.
• Handoff for Next Session — emit the update confirmation, then the layout-detected (V2/V1/NONE) handoff brief.
• Commit offer (part (c)) — after the handoff brief, run the template's consent-gated, baseline-safe, no-push commit offer, passing the pre-flight baseline $BASELINE_REPO you captured for the project repo.

Both are READ-only over already-updated state files; the skill makes no further edits here.

Notes

• This skill no longer reads or edits files directly. All file work happens inside the sub-agent's isolated context, which keeps the main session's context window slim.
• Layer boundaries (what belongs in repo docs vs wiki vs Notion) are inlined in the sub-agent's system prompt — not duplicated here.
• Step 5's stale-candidate review and handoff brief live in templates/post-propagation-steps.md (shared with /up-docs:all) — the single source of truth for both. git rm deletions require explicit AskUserQuestion consent; layout detection (V2/V1/NONE) is probe-based, not flag-based.
• No drift audit. This skill propagates only the current session's named changes; it does not run the up-docs-audit-drift auditor. Pre-existing drift your session didn't touch (stale versions, renamed-file references, outdated labels) is invisible here — run /up-docs:drift or /up-docs:all periodically (e.g. after a release) to catch it.
