# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [3.1.0] - 2026-04-14

### Summary
New read-only command `/config-audit whats-active` — shows exactly what Claude Code loads for a given repo, with token estimates.

### Added
- **`/config-audit whats-active [path]`** — inventory of active plugins, skills, MCP servers, hooks, and CLAUDE.md cascade for a repo, with source attribution (user/project/plugin) and rough token estimates. Read-only, <2s.
- `scanners/lib/active-config-reader.mjs` — pure async helper: `readActiveConfig()`, `detectGitRoot()`, `walkClaudeMdCascade()`, `readClaudeJsonProjectSlice()` (longest-prefix matching), `enumeratePlugins()`, `enumerateSkills()`, `readActiveHooks()`, `readActiveMcpServers()`, `estimateTokens()`.
- `scanners/whats-active.mjs` — thin CLI shim supporting `--json`, `--output-file`, `--verbose`, `--suggest-disables`.
- Optional `--suggest-disables` flag surfaces deterministic disable candidates (disabled MCP servers, zero-item plugins, unreferenced plugins, orphan skills) and invites an LLM judgment pass in the command.
- 36 new tests in `tests/lib/active-config-reader.test.mjs`, plus a `rich-repo` tmpdir fixture helper.

### Changed
- Version bump: `3.0.1` → `3.1.0` (minor, additive feature, no breaking changes).
- Command count: 15 → 16.

## [3.0.1] - 2026-04-04

### Summary
Cross-platform fix — scanners, hooks, and lib now work correctly on Windows.

### Fixed
- `file-discovery.mjs`: depth calculation, agent/command/plugin path matching now use `path.sep`
- `scan-orchestrator.mjs`: fixture-path filtering now uses `path.sep`
- `post-edit-verify.mjs`: rules-dir regex handles both `/` and `\` separators
- `auto-backup-config.mjs`: rules-dir detection now uses `path.sep`
- `import-resolver.mjs`: circular import display uses `basename()`, `/tmp` fallback replaced with `os.tmpdir()`
- `string-utils.mjs`: `normalizePath` trailing separator regex handles both `/` and `\`

### Added
- 4 cross-platform path tests (total 486 tests)

## [3.0.0] - 2026-04-04

### Summary
Health redesign — configuration health is now quality-only. Feature utilization removed from grades entirely.

### Changed
- **Health = quality only.** 7 deterministic scanners (CML, SET, HKV, RUL, MCP, IMP, CNF) determine your grade. Feature Coverage is no longer a graded area.
- **Feature recommendations are opt-in.** Unused features shown as "opportunities" via `/config-audit feature-gap`, grouped by impact (high/medium/explore), backed by Anthropic docs. No more "Feature Coverage: F" for correct minimal setups.
- **Posture output redesigned.** Shows `Health: {grade} ({score}/100)` with 7 quality areas. Removed utilization %, maturity level, segment label.
- **Feature-gap is interactive.** Users select recommendations to implement directly — no manual file editing required. Backup created automatically.
- **avgScore bug fixed.** Grade letter and displayed score now computed from the same population (quality areas only).

### Added
- `generateHealthScorecard()` in scoring.mjs — quality-only scorecard
- `opportunitySummary()` in feature-gap-scanner.mjs — groups findings by impact tier
- `opportunityCount` field in posture JSON output
- "Official Configuration Guidance" section in knowledge base (Anthropic docs, proven impacts)
- 21 new tests (total 482 across 27 test files)

### Removed
- `S2-PROMPT.md` and `V2-ANNOUNCEMENT.md` — v2 development artifacts
- Utilization %, maturity level, segment label from posture terminal output and reports
- Feature Coverage row from area breakdown tables
- "Top Actions" sourced from GAP findings (replaced by opportunities pointer)

### Backward Compatibility
- JSON output preserves all legacy fields (utilization, maturity, segment) for programmatic consumers
- Drift baselines unaffected — GAP findings still present in envelopes
- All existing exports maintained (calculateUtilization, determineMaturityLevel, etc.)

## [2.2.0] - 2026-04-04

### Summary
UX quality fix — fixture filtering, session path migration, output polish.

### Added
- Automatic test-fixture filtering in scan-orchestrator: findings from `tests/`, `examples/`, `__tests__/` excluded from grades, stored in `env.fixture_findings`
- `--include-fixtures` CLI flag for scan-orchestrator and posture to override filtering
- `scan-orchestrator.test.mjs` — 20 new tests for fixture filtering and `isFixturePath`
- Legacy session path detection in cleanup command

### Changed
- Session storage moved from `~/.config-audit/` to `~/.claude/config-audit/` (pathguard compatible)
- Self-audit grade: F → A (98) after fixture filtering
- Combined scanner + posture into single Bash call in default audit command
- Removed "F grade is misleading" disclaimer — grades are now accurate
- All CLI banners and envelope metadata updated to v2.2.0
- 461 tests (up from 441), 27 test files (up from 26)

### Removed
- Manual fixture counting instruction in `config-audit.md` (orchestrator handles it)
- Redundant `isFixtureOrExample` filter in `self-audit.mjs` (promoted to orchestrator)

## [2.1.0] - 2026-04-03

### Summary
UX redesign — auto-scope detection, zero questions, simplified command surface.

### Changed
- `/config-audit` now runs full audit automatically (auto-detects scope from git context)
- Removed mode selection prompts — scope override via `/config-audit full|repo|home|current`
- Simplified from 17 to 15 commands (removed quick, report, watch; added help)
- All CLI banners and envelope metadata updated to v2.1.0

### Added
- `/config-audit help` command with categorized command reference
- Auto-scope detection from git context (repo vs home vs full-machine)

### Removed
- `/config-audit:quick` (merged into default `/config-audit`)
- `/config-audit:report` (merged into analyze output)
- `/config-audit:watch` (use `/config-audit drift` instead)

## [2.0.0] - 2026-04-03 (v2.0 Complete)

## [1.2.0] - 2026-04-03 (v2.0 S2: Advanced Scanners + Knowledge Base)

### Added
- **4 advanced scanners** (zero external deps):
  - `mcp-config-validator.mjs` (MCP) — server types, trust levels, env vars, unknown fields

  - `feature-gap-scanner.mjs` (GAP) — 25 feature gaps across 4 tiers (Foundation/Depth/Advanced/Enterprise)
- **Knowledge base** — 5 reference documents: capabilities, best practices, anti-patterns, hook events, feature evolution
- **New test fixtures** — `.mcp.json` files, @import chains, `conflict-project/` fixture
- 75 new tests (total 204 across 12 test files)

### Changed

- **Test infrastructure** — 129 tests across 8 test files using node:test (zero deps)
- **Test fixtures** — 4 fixture projects (healthy, broken, empty, minimal)
- Finding ID format: `CA-{SCANNER}-{NNN}` (e.g. `CA-CML-001`)

### Fixed
- Agent model mismatches: scanner→haiku, analyzer→sonnet, planner→opus, implementer→sonnet, verifier→haiku

### Changed
- CLAUDE.md rewritten in English for public release readiness

## [1.0.0] - 2026-02-11

### Added
- Cross-platform support (macOS, Linux, Windows)

### Fixed

- `backup-before-change.mjs`: Handle both `/` and `\` path separators in safe filename generation

### Removed
- "Windows: hooks are 100% bash" from known gaps (was incorrect — all hooks are Node.js)

## [0.7.0] - 2026-02-07

### Note
Version reset from 1.2.0 to reflect actual maturity. Previous version was inflated — this plugin has never been externally tested.

### What exists today
- 6 specialized agents (scanner, analyzer, interviewer, planner, implementer, verifier)
- Full machine-wide Claude Code configuration discovery
- Scope selection (current project, repo, home, full machine)
- Inheritance hierarchy mapping and conflict detection
- Mandatory backups before any changes
- Rollback support
- Syntax validation for all configuration files
- Quick audit-only mode
- Full optimization workflow with HITL checkpoints

### Known gaps
- Testing: no automated tests
- Onboarding: never verified that a new user can install and use from scratch
- External verification: nobody else has ever used this
