- Removed the standalone vim tool and normalized built-in/requested tooling to edit.
- Updated session and SDK tool activation to dedupe lowercase names and track edit state via the edit key.
- Added vim-mode argument detection and delegated edit rendering/execution into Vim handlers under edit.
- Updated Vim step handling to auto-reorder numeric-positioned commands, including cc/C/S/s/i/I/A cases.
- Renamed prompt/changelog text and test expectations to reflect edit-only tool naming and usage.
- Fixed Vim path normalization to allow colon-prefixed targets without raising ToolError.
- Documented the new Vim path behavior in the package changelog.
- Updated chunk-edit benchmark prompts to read `test.rs` for edit and retry operations.
- Updated vim benchmark flow to use `vim`+`read`, import expected content, and display final expected output.
- Expanded benchmark fixtures to generate Rust `test.rs`, compute unified diffs, and add richer pool logic.
- Added `toolStrictMode` support with `all_strict`/`none`/`mixed` options to OpenAI compatibility.
- Fixed OpenAI-completion strict-mode flows by capturing failed HTTP responses and retrying once as non-strict.
- Fixed completion error reporting by surfacing captured status, headers, and JSON `type`/`param`/`code` details.
- Improved strict-schema enforcement with WeakMap memoization and circular-schema detection in sanitization.
- Fixed OpenRouter provider lookup by resolving fallback model IDs for suffix and date variants in registry resolution.
- Refactored benchmark tooling and added async RPC error-window tracking for scheduled run execution.
- Added `<escape>` and `<return>` as special-key aliases in `parser.ts`, mapping to `Esc` and `CR`.
- Clarified Vim tool behavior so `open` replaces the active buffer and non-paused `kbd` calls auto-save.
- Updated the Vim prompt contract to treat `insert` as raw text entered only after entering INSERT mode.
- Increased `scripts/vim-edit-benchmark.py` `request_timeout` from 60s to 120s for longer edit runs.
- Added `VimTool` in `src/tools/vim.ts` with `open`, `kbd`, `insert`, and `pause` actions.
- Implemented `src/vim/{buffer,engine,parser,commands,render,types}.ts` for interactive Vim modes and operators.
- Updated `src/tools/index.ts` to normalize `edit`/`vim` tool selection and skip the inactive edit variant.
- Added `vim` registration in `BUILTIN_TOOLS` and `toolRenderers` for discoverability and output formatting.
- Added streaming renderer snapshots with viewport, caret focus, and diff output for `vim` calls.
- Added `test/tools/vim.test.ts` and `scripts/vim-edit-benchmark.py` coverage for the new editor stack.
