v5.0 — Three new skills + session health check
New Skills (3)
/freeze — Scope lock before implementation
- Parses your input to classify files as editable, frozen, or read-only
- Emits a
FROZEN SCOPEblock and stops — no code generation, no agents - Ambiguous scope → one clarifying question; still vague → freeze the broader scope
- Adapted from garrytan/gstack freeze pattern (task-scoped, no session state)
/retro — Milestone retrospective
- 6-phase pipeline: scope → friction points (root cause) → wins → pattern extract → lessons write → summary
- Duplicate check before writing — updates
obs/seenon existing lessons.md matches - Complements session-checkpoint Reflexion (session-scoped); retro is milestone-scoped and goes deeper
/token-audit — Token overhead measurement
- Measures actual overhead from your session JSONL — not estimates
- Turn-weighted averaging across 8 categories (config baseline, memory re-reads, skill loading, agent overhead, etc.)
- Optional dark-theme infographic with 6 panels (
pip install matplotlib) - Benchmark: standard setups 35–50% overhead, heavy agent systems 50–65%
Enhancements
/session-start — Phase 0.5: Environment Health Check (runs every session)
- Checks
~/.claude/settings.jsonmodel ID against known-valid Claude identifiers - Counts
permissions.allowentries — warns if > 5 (silent permission surface growth)
/project-check — Safety Layers + Error Recovery
- Explicit table of blocked actions mapped to Invariants — read-only guarantee is now auditable
- Failure classification table: partial scans report as partial, never as complete
Usability fixes across the suite:
