- Aligned handoff, reminder, and system-prompt expectations with shortened copy.
- Added HTTP transport test for required initialize failures.
- Guarded SSE startup timeout against stale connection races.
- Grouped `isRepository`, `workspaceRoot`, and `clearWorkspaceRootCache` under a `repo` namespace (`repo.is`, `repo.root`, `repo.clearRootCache`).
- Promoted `diff` to a named export with a `changedFiles` sub-method via `Object.assign`.
- Added `ensureAvailable` check and `nameOnly` support to `diff`.
- Updated callers and tests to use the new API surface.
- Replaced `jj workspace root` subprocess call with a local `.jj/repo/store` directory traversal, eliminating process spawning overhead.
- Added LRU cache for resolved workspace roots to avoid redundant filesystem walks.
- Renamed internal `runCommand` helpers to `git`/`jj` for clarity.
- Replaced git subprocess setup in review test with mocked `git.status` and `git.diff` calls.
- Added canonical `pi.zod` schema API exports and removed TypeBox package exports/imports.
- Migrated Tool schema typing from TypeBox to shared `TSchema`/Zod flow with legacy TypeBox compatibility.
- Updated AI provider adapters and MCP/agent builders to convert tool params through `toolWireSchema()`.
- Reworked schema validation from AJV to Zod-safe parsing with `fromTypeBox`, `toolWireSchema`, and meta schema checks.
- Consolidated all former gh_* tools into a single GithubTool that routes execution by a required op field.
- Replaced gh_* tool registrations and render dispatch with `github`, including renderer key and header updates.
- Removed deprecated gh-* tool prompt files and added a unified github.md prompt covering per-op inputs and outputs.
- Updated settings-schema and ci-green prompt guidance to reference the unified github tool and `run_watch` operation.
- Updated tests and tool imports to use `GithubTool`/`githubToolRenderer` with op-based payloads and assertions.
- Fixed PR checkout tool to resolve worktree paths to canonical form using fs.realpath().
- Refactored test mocks to use vi.spyOn for git module functions instead of inline implementations.
- Updated test setup to pass Settings.isolated() with edit.manageImports enabled to EditTool.
- Added afterEach hooks across test suites to restore mocks after each test execution.
