kb-compact

name	kb-compact
description	Compacts KB directories — extracts legacy, unifies terminology, splits oversized notes, fixes indexes, reconciles with skill folders. Default: single directory. Use --deep for recursive bottom-up traversal.
argument-hint	[--deep] [path/to/directory]

/kb-compact

1. Configuration

Read KB config from .claude/knowledge-base/config.json (kb_roots array). Single KB: use its path. Multiple: AskUserQuestion which KB. No config: tell user "Run /kb-bootstrap to set up." and stop.

2. Input

Parse $ARGS:

• --deep: recursive bottom-up traversal. Without it: single directory only.
• path: optional, relative to project root or <kb_root>.
• No path: ask user. Offer "Compact whole KB" (warn: expensive, implies --deep) or specify subfolder.

3. Folder Structure

All restructuring follows reference/folder-structure.md (canonical for clustering, unification, indexes, naming).

Sibling unification first: child folders grouped by semantically/lexicographically close names, run before other steps. 5+ siblings = medium sign; 8+ = high.

Template: assets/index-note.md

4. Orchestration

• Default: Single compacter agent for target directory.
• --deep: Follow reference/deep-compaction.md — tree analysis, level-based parallel compacter agents, bottom-up.

5. Changelog

Every run changing knowledge files MUST prepend to <kb-root>/CHANGELOG.md per ${CLAUDE_SKILL_DIR}/../learn/reference/changelog-workflow.md.

6. User Approval

After all agents complete: present combined summary (files processed/moved/merged/split/created/deleted, terminology, legacy, indexes). AskUserQuestion: "Keep all", "Revert selectively", "Revert all". Selective: per-directory summaries, revert via git checkout -- <paths>.

7. Validation

After completing KB changes, run the validator to catch broken links, frontmatter issues, and structural errors:

uv run ${CLAUDE_SKILL_DIR}/../learn/scripts/validate_kb.py --quiet --json

Fix any reported errors before finishing.
