- `review` builtin piece with 3-mode auto-detection: automatically selects PR mode (by PR number), branch mode (by branch name), or working diff mode (by free text) for multi-perspective parallel review
- `testing-reviewer` and `requirements-reviewer` builtin personas for specialized review perspectives
- `testing` policy: integration test requirement criteria (3+ module data flow, state merging into workflows, option propagation through call chains)
- `gather-review` instruction and `review-gather` output contract for the new review piece gather movement
- `requirements-review` instruction and output contract for requirements-focused review
- `testing-review` output contract for testing-focused review
- `settingSources: ['project']` in SDK options: delegates CLAUDE.md loading to the Claude SDK for proper project-level settings resolution

### Changed

- **BREAKING:** `review-only` piece renamed to `review`; `review-fix-minimal` piece removed — users referencing these piece names must update to `review`
- `write-tests-first` instruction now includes integration test decision criteria instead of a generic "Write E2E tests if appropriate"

### Fixed

- Planner persona: added bug fix propagation check rule (grep for same pattern in related files) and prohibited deferring decidable questions to Open Questions

### Internal

- Docs: fixed music metaphor origin description, catalog gaps, broken links, orphaned documents, event names, API Key references, eject descriptions, removed stale personas section map from YAML example, aligned legacy terminology with current codebase
- New test suites: `StreamDisplay`, `ask-user-question-handler`, `pieceExecution-ask-user-question`, `review-piece`, `opencode-client-cleanup`
- Removed legacy `review-only-piece` test and `loadProjectContext` from session module (CLAUDE.md loading now delegated to SDK)

## [0.23.0] - 2026-02-23

### Added

- `default-test-first-mini` builtin piece for test-first development workflow
- `auto_fetch` global config: opt-in remote fetch before cloning to keep clones up-to-date (`default: false`)
- `base_branch` config (global/project): specify the base branch for clone creation (defaults to remote default branch)
- `model` project config: override model at the project level (`.takt/config.yaml`)
- `concurrency` project config: set parallel task count per project for `takt run`
- `--create-worktree` support in pipeline mode for worktree-based execution
- `skipTaskList` option: interactive "Execute" action skips adding to `tasks.yaml`
- `takt list` now displays GitHub Issue numbers alongside task names
- Retry failed tasks now offers to reuse the previous piece before prompting piece selection
- Pipeline mode Slack notifications: sends run summary with task details, duration, branch, and PR URL
- CI workflow: lint, test, and e2e:mock checks run automatically on PRs (#364)

### Changed

- Provider/model resolution unified via `resolveProviderModelCandidates()` — single resolution function used in both `AgentRunner` and `resolveMovementProviderModel`
- Pipeline execution refactored into thin orchestrator (`execute.ts`) + step implementations (`steps.ts`)
- Clone directory default changed from `takt-worktree` (singular) to `takt-worktrees` (plural) with auto-migration of legacy directory
- PR titles now include issue number prefix (e.g., `[#6] Fix the bug`)
- Task status now reflects PR creation failure — previously only piece execution success was tracked
- `auto-tag.yml` tags PR head SHA instead of merge commit for correct hotfix code publishing
- Session reader falls back to JSONL file scanning when `sessions-index.json` is missing or invalid
- `ProjectLocalConfig` type normalized to camelCase (`auto_pr`→`autoPr`, `draft_pr`→`draftPr`) — YAML snake_case preserved
- `getLocalLayerValue` simplified from switch-case to dynamic property lookup

### Fixed

- `repertoire add` pipe stdin: multiple `confirm()` calls failed when reading from piped stdin due to readline destroying buffered lines (#334)
- Movement provider override precedence in `AgentRunner`: step provider was incorrectly overridden by global config
- Project-level `model` config was silently ignored — `getLocalLayerValue` was missing the `model` case
- PR creation failure now properly propagated as task failure with error message (#345)
- Claude session resume candidates now fall back to JSONL file scanning when `sessions-index.json` is unavailable

### Internal

- CI: PR checks for lint, test, e2e:mock (`ci.yml`)
- Expanded e2e test coverage for repertoire (#364)
- New test suites: clone, config, postExecution, session-reader, selectAndExecute-skipTaskList, taskStatusLabel, pipelineExecution
- Refactored: project config case normalization (#358), clone manager (#359), pipeline steps extraction, confirm pipe reader singleton, provider resolution (#362)

## [0.22.0] - 2026-02-22

### Added

- **Repertoire package system** (`takt repertoire add/remove/list`): Import and manage external TAKT packages from GitHub — `takt repertoire add github:{owner}/{repo}@{ref}` downloads packages to `~/.takt/repertoire/` with atomic installation, version compatibility checks, lock files, and package content summary before confirmation
- **@scope references in piece YAML**: Facet references now support `@{owner}/{repo}/{facet-name}` syntax to reference facets from installed repertoire packages (e.g., `persona: @nrslib/takt-fullstack/expert-coder`)
- **4-layer facet resolution**: Upgraded from 3-layer (project → user → builtin) to 4-layer (package-local → project → user → builtin) — repertoire package pieces automatically resolve their own facets first
- **Repertoire category in piece selection**: Installed repertoire packages automatically appear as subcategories under a "repertoire" category in the piece selection UI
- **Build gate in implement/fix instructions**: `implement` and `fix` builtin instructions now require build (type check) verification before test execution
- **Repertoire package documentation**: Added comprehensive docs for the repertoire package system ([en](./docs/repertoire.md), [ja](./docs/repertoire.ja.md))

### Changed

- **BREAKING: Facets directory restructured**: Facet directories moved under a `facets/` subdirectory at all levels — `builtins/{lang}/{facetType}/` → `builtins/{lang}/facets/{facetType}/`, `~/.takt/{facetType}/` → `~/.takt/facets/{facetType}/`, `.takt/{facetType}/` → `.takt/facets/{facetType}/`. Migration: move your custom facet files into the new `facets/` subdirectory
- Contract string hardcoding prevention rule added to coding policy and architecture review instruction

### Fixed

- Override piece validation now includes repertoire scope via the resolver
- `takt export-cc` now reads facets from the new `builtins/{lang}/facets/` directory structure
- `confirm()` prompt now supports piped stdin (e.g., `echo "y" | takt repertoire add ...`)
- Suppressed `poll_tick` debug log flooding during iteration input wait
- Piece resolver `stat()` calls now catch errors gracefully instead of crashing on inaccessible entries

### Internal

- Comprehensive repertoire test suite: atomic-update, repertoire-paths, file-filter, github-ref-resolver, github-spec, list, lock-file, pack-summary, package-facet-resolution, remove-reference-check, remove, takt-repertoire-config, tar-parser, takt-repertoire-schema
- Added `src/faceted-prompting/scope.ts` for @scope reference parsing, validation, and resolution
- Added scope-ref tests for the faceted-prompting module
- Added `inputWait.ts` for shared input-wait state to suppress worker pool log noise
- Added piece-selection-branches and repertoire e2e tests

## [0.21.0] - 2026-02-20

### Added

- **Slack task notification enhancements**: Extended Slack webhook notifications with richer task context and formatting (#316)

- **Analytics project config and env override**: Analytics settings can now be configured per-project and overridden via environment variables
- **CI dependency health check**: Periodic CI check to detect broken dependency packages

### Changed

- **Config system overhaul**: Replaced `loadConfig()` bulk merge with per-key `resolveConfigValue()` resolution — global < piece < project < env priority with source tracking and `OptionsBuilder` merge direction control (#324)

### Fixed

- **Retry command scope and messaging**: Fixed retry command to show correct available range and guidance text
- **Retry task `completed_at` leak**: Clear `completed_at` when moving a failed task back to running via `startReExecution`, preventing Zod validation errors
- **OpenCode multi-turn hang**: Removed `streamAbortController.signal` from OpenCode server startup so subsequent turns no longer hang; restored `sessionId` carry-over for multi-turn conversations
- **Romaji conversion stack overflow**: Prevented stack overflow on long task names during romaji conversion

## [0.20.1] - 2026-02-20

### Fixed

- Pin `@opencode-ai/sdk` to `<1.2.7` to fix broken v2 exports that caused `Cannot find module` errors on `npm install -g takt` (#329)

## [0.20.0] - 2026-02-19

### Added

- **Faceted Prompting module** (`src/faceted-prompting/`): Standalone library for facet composition, resolution, template rendering, and truncation — zero dependencies on TAKT internals. Includes `DataEngine` interface with `FileDataEngine` and `CompositeDataEngine` implementations for pluggable facet storage
- **Analytics module** (`src/features/analytics/`): Local-only review quality metrics collection — event types (review findings, fix actions, movement results), JSONL writer with date-based rotation, report parser, and metrics computation
- **`takt metrics review` command**: Display review quality metrics (re-report counts, round-trip ratio, resolution iterations, REJECT counts by rule, rebuttal resolution ratio) with configurable time window (`--since`)
- **`takt purge` command**: Purge old analytics event files with configurable retention period (`--retention-days`)
- **`takt reset config` command**: Reset global config to builtin template with automatic backup of the existing config
- **PR duplicate prevention**: When a PR already exists for the current branch, push and comment on the existing PR instead of creating a duplicate (#304)
- Retry mode now positions the cursor on the failed movement when selecting which movement to retry
- E2E tests for run-recovery and config-priority scenarios

### Changed

- **README overhaul**: Compressed from ~950 lines to ~270 lines — details split into dedicated docs (`docs/configuration.md`, `docs/cli-reference.md`, `docs/task-management.md`, `docs/ci-cd.md`, `docs/builtin-catalog.md`) with Japanese equivalents. Redefined product concept around 4 value axes: batteries included, practical, reproducible, multi-agent
- **Config system refactored**: Unified configuration resolution to `resolveConfigValue()` and `loadConfig()`, eliminating scattered config access patterns across the codebase
- **`takt config` command removed**: Replaced by `takt reset config` for resetting to defaults
- Builtin config templates refreshed with updated comments and structure
- `@anthropic-ai/claude-agent-sdk` updated to v0.2.47
- Instruct mode prompt improvements for task re-instruction

### Fixed

- Fixed issue where builtin piece file references used absolute path instead of relative (#304)
- Removed unused imports and variables across multiple files

### Internal

- Unified `loadConfig`, `resolveConfigValue`, piece config resolution, and config priority paths
- Added E2E tests for config priority and run recovery scenarios
- Added `postExecution.test.ts` for PR creation flow testing
- Cleaned up unused imports and variables

## [0.19.0] - 2026-02-18

### Added

- Dedicated retry mode for failed tasks — conversation loop with failure context (error details, failed movement, last message), run session data, and piece structure injected into the system prompt
- Dedicated instruct system prompt for completed/failed task re-instruction — injects task name, content, branch changes, and retry notes directly into the prompt instead of using the generic interactive prompt
- Direct re-execution from `takt list` — "execute" action now runs the task immediately in the existing worktree instead of only requeuing to pending
- `startReExecution` atomic task transition — moves a completed/failed task directly to running status, avoiding the requeue → claim race condition
- Worktree reuse in task execution — reuses existing clone directory when it's still on disk, skipping branch name generation and clone creation
- Task history injection into interactive and summary system prompts — completed/failed/interrupted task summaries are included for context
- Previous run reference support in interactive and instruct system prompts — users can reference logs and reports from prior runs
- `findRunForTask` and `getRunPaths` helpers for automatic run session lookup by task content
- `isStaleRunningTask` process helper extracted from TaskLifecycleService for reuse

### Changed

- Interactive module split: `interactive.ts` refactored into `interactive-summary.ts`, `runSelector.ts`, `runSessionReader.ts`, and `selectorUtils.ts` for better cohesion
- `requeueTask` now accepts generic `allowedStatuses` parameter instead of only accepting `failed` tasks
- Instruct/retry actions in `takt list` use the worktree path for conversation and run data lookup instead of the project root
- `save_task` action now requeues the task (saves for later execution), while `execute` action runs immediately

### Internal

- Removed `DebugConfig` from models, schemas, and global config — simplified to verbose mode only
- Added stdin simulation test helpers (`stdinSimulator.ts`) for E2E conversation loop testing
- Added comprehensive E2E tests for retry mode, interactive routes, and run session injection
- Added `check:release` npm script for pre-release validation

## [0.18.2] - 2026-02-18

### Added

- Added `codex_cli_path` global config option and `TAKT_CODEX_CLI_PATH` environment variable to override the Codex CLI binary path used by the Codex SDK (#292)
  - Supports strict validation: absolute path, file existence, executable permission, no control characters
  - Priority: `TAKT_CODEX_CLI_PATH` env var > `codex_cli_path` in config.yaml > SDK vendored binary

## [0.18.1] - 2026-02-18

### Added

- Added multi-tenant data isolation section and authorization-resolver consistency code examples to security knowledge
- Added "prefer project scripts" rule to coding policy — detects direct tool invocation (e.g., `npx vitest`) when equivalent npm scripts exist

## [0.18.0] - 2026-02-17

### Added

- **`deep-research` builtin piece**: Multi-angle research workflow with four steps — plan, deep-dive, analyze, and synthesize
- Project-level `.takt/` facets (pieces, personas, policies, knowledge, instructions, output-contracts) are now version-controllable (#286)
- New research facets added: research policy, knowledge, comparative-analysis knowledge, dedicated persona, and instructions

### Changed

- Refactored the `research` piece — separated rules and knowledge embedded in the persona into policy, knowledge, and instruction files, conforming to the faceted design
- Added knowledge/policy references to existing pieces (expert, expert-cqrs, backend, backend-cqrs, frontend)

### Fixed

- Fixed a bug where facet directories were not tracked because `.takt/` path prefix was written with `.takt/` prefix in the `.takt/.gitignore` template (dotgitignore)

### Internal

- Created knowledge facet style guide (`KNOWLEDGE_STYLE_GUIDE.md`)
- Added regression tests for dotgitignore patterns

## [0.17.3] - 2026-02-16

### Added

- Added API client generation consistency rules to builtin AI anti-pattern policy and frontend knowledge — detects handwritten clients mixed into projects where generation tools (e.g., Orval) exist

### Fixed

- Fixed EPERM crash when releasing task store locks — replaced file-based locking with in-memory guard

### Internal

- Unified vitest configuration for e2e tests and added `forceExit` option to prevent zombie workers

## [0.17.2] - 2026-02-15

### Added

- **`expert-mini` and `expert-cqrs-mini` pieces**: Lightweight variants of Expert pieces — plan → implement → parallel review (AI anti-pattern + supervisor) → fix workflow
- Added new pieces to "Mini" and "Expert" piece categories

### Fixed

- Fixed an error being thrown when permission mode could not be resolved — now falls back to `readonly`

## [0.17.1] - 2026-02-15

### Changed

- Changed `.takt/.gitignore` template to allowlist approach — ignores all files by default and tracks only `config.yaml`. Prevents ignore gaps when new files are added

## [0.17.0] - 2026-02-15

### Added

- **Mini piece series**: Added `default-mini`, `frontend-mini`, `backend-mini`, `backend-cqrs-mini` — lightweight development pieces with parallel review (AI anti-pattern + supervisor) as successors to `coding`/`minimal`
- Added "Mini" category to piece categories
- **`supervisor-validation` output contract**: Requirements Fulfillment Check table format that presents code evidence per requirement
- **`getJudgmentReportFiles()`**: Phase 3 status judgment target reports can now be filtered via `use_judge` flag
- Added `finding_id` tracking to output contracts (new/persists/resolved sections for tracking findings across iterations)

### Changed

- **BREAKING: Removed `coding` and `minimal` pieces** — replaced by the mini piece series. Migration: `coding` → `default-mini`, `minimal` → `default-mini`
- **BREAKING: Unified output contract to item format** — `use_judge` (boolean) and `format` (string) fields are now required; `OutputContractLabelPath` (label:path format) is removed
- Moved runtime environment directory from `.runtime` to `.takt/.runtime`
- Enhanced supervisor requirements verification: extracts requirements individually and verifies one-by-one against code (file:line) — "roughly complete" is no longer valid grounds for APPROVE

### Fixed

- Added retry mechanism for deleting clone/worktree directories (`maxRetries: 3`, `retryDelay: 200`) — reduces transient deletion failures caused by file locks

### Internal

- Removed `review-summary` output contract (consolidated into `supervisor-validation`)
- Updated all builtin pieces, e2e fixtures, and tests to the new output contract format

## [0.16.0] - 2026-02-15

### Added

- **Provider-specific permission profiles (`provider_profiles`)**: Define default permission modes per provider and per-movement overrides in global (`~/.takt/config.yaml`) and project (`.takt/config.yaml`) config — 5-level priority resolution (project override → global override → project default → global default → `required_permission_mode` floor)

### Changed

- **BREAKING: `permission_mode` → `required_permission_mode`**: Renamed movement's `permission_mode` field to `required_permission_mode` — acts as a floor value; the actual permission mode is resolved via `provider_profiles`. Old `permission_mode` is rejected by `z.never()`, no backward compatibility
- Rewrote builtin `config.yaml` template: reorganized comments, added `provider_profiles` description and examples, added OpenCode-related settings

### Internal

- Added tests for provider profile resolution (global-provider-profiles, project-provider-profiles, permission-profile-resolution, options-builder)
- Added missing `loadProjectConfig` mock to parallel execution tests

## [0.15.0] - 2026-02-15

### Added

- **Runtime environment presets**: `piece_config.runtime.prepare` and global config `runtime.prepare` allow environment preparation scripts to run automatically before piece execution — builtin presets (`gradle`, `node`) isolate dependency resolution and cache setup to the `.runtime/` directory
- **Loop monitor judge instruction**: `loop_monitors` judge config now supports `instruction_template` field — externalizes loop judgment instructions as an instruction facet, applied to builtin pieces (expert, expert-cqrs)

### Internal

- Added runtime environment tests (runtime-environment, globalConfig-defaults, models, provider-options-piece-parser)
- Added provider e2e test (runtime-config-provider)

## [0.14.0] - 2026-02-14

### Added

- **`takt list` instruct mode (#267)**: Added instruct mode for issuing additional instructions to existing branches — refine requirements through a conversation loop before piece execution
- **`takt list` completed task actions (#271)**: Added diff view and branch operations (merge, delete) for completed tasks
- **Claude sandbox configuration**: `provider_options.claude.sandbox` supports `excluded_commands` and `allow_unsandboxed_commands`
- **`provider_options` global/project config**: `provider_options` can now be set in `~/.takt/config.yaml` (global) and `.takt/config.yaml` (project) — acts as lowest-priority fallback for piece-level settings

### Changed

- **Consolidated provider/model resolution into AgentRunner**: Fixed provider resolution to prioritize project config over custom agent config. Added step-level `stepModel`/`stepProvider` overrides
- **Unified post-execution flow**: Shared `postExecution.ts` for interactive mode and instruct mode (auto-commit, push, PR creation)
- **Added scope-narrowing prevention to instructions**: plan, ai-review, and supervise instructions now require detecting missed requirements — plan mandates per-requirement "change needed/not needed" judgments with rationale, supervise prohibits blindly trusting plan reports

### Fixed

- Fixed a bug where interactive mode options were displayed during async execution (#266)
- Fixed OpenCode session ID not being carried over during parallel execution — server singleton prevents race conditions in parallel runs
- Extended OpenCode SDK server startup timeout from 30 seconds to 60 seconds
