compare — Read-only Retrospective
Step 1: Scope HITL (one-shot)
Ask: "Retrospective scope — repo or global?"
Step 2: Assets presence check
If .honne/assets/ absent or empty: Print "No assets yet. Run honne first." and exit 0.
Step 3: Load claims + evolutions
bash "${CLAUDE_PLUGIN_ROOT}/scripts/query-assets.sh" \
--tag "<axis>" --scope "$SCOPE" --type claim --out stdout
bash "${CLAUDE_PLUGIN_ROOT}/scripts/query-assets.sh" \
--type evolution --scope "$SCOPE" --out stdout
Async wait pattern — use Monitor until-loop, not sleep N && cat:
# ✓ Monitor: until [ -f ".honne/assets/claim.jsonl" ]
Step 4: Time-bucket grouping
Group by axis × recorded_at bucket (YYYY-MM granularity for MVP).
Step 5: Render docs/honne-compare.md (+ stdout)
Format per architecture PRD §4.2 compare Step 6. No LLM unless the user asked for "summarize" — and even then, only cite-bound.
Step 6: Asset immutability check
This skill MUST NOT write to .honne/assets/ or .honne/persona.json. Verify (test): stat -c %Y on assets/*.jsonl before/after unchanged.
