- Added `normalizeSystemPrompts` and applied it to context normalization before building provider request payloads.

- Aligned tests and changelogs to pass and assert `systemPrompt` as arrays with ordered prompt semantics.
- Removed `id` fields from todo models/fixtures and switched session clones to content-based task identity.
- Replaced `/todo_write` `replace` with `init`, updated setup schemas to `list`/`phase`, and append content-only items.
- Updated `/todo` command flows to match phases and tasks by names/content (exact/prefix/substr, case-insensitive), with no ID targeting.
- Updated rendering/output labels to `# Todos`, `formatPhaseDisplayName`, and Roman-numeral phase headings across todo views.
- Aligned prompts, changelog, and todo tests/fixtures with the new init and content-based todo-write contract.
- Added auto-rebasing for stale atom and hashline anchors within ±2 lines, with warning diagnostics.
- Removed atom range-locator support and dropped `between` ops, updating docs/tests for `sub` over `set` nudges.
- Changed no-op handling to track unchanged hashline edits and emit contextual hints for unchanged ranges.
- Expanded Anthropic strict error handling to retry on schema-too-complex and compiled-grammar-too-large errors.
- Added anchor-retargeting warning checks and updated edit tests to expect locator and range-locator rejections.
- Updated python tool-call fixtures by adding `title` to executed-cell payloads and adjusting related test expectations.
- Changed the todo-write parameter schema from a bare operations array to an object containing an `ops` array.
- Updated request parsing and renderer logic to consume `params.ops` and `args.ops` when processing todo operations.
- Updated session and unit tests to invoke todo_write with wrapped `{ ops: [...] }` payloads.
- Changed `todo_write` to an ordered `op`-array model with `replace`, `start`, `done`, `rm`, `drop`, `append`.
- Removed legacy multi-field todo payloads and updated tests/fixtures to use ordered `{op, task?, phase?, items?}[]` args.
- Reworked todo operation execution to apply entries sequentially and validate missing or unknown task/phase IDs.
- Updated todo rendering to use `todo.content` only and changed bash artifact labels from `full result` to `raw output`.
- Standardized missing-file read errors and now return `File not found: <path>` for absent edit targets.
- Centralized AI provider, usage, and OAuth helpers into shared modules to remove duplicated logic.
- Migrated OAuth/API-key login flows to shared factory helpers and removed inline prompt/token-exchange code.
- Reused shared tools and formatter utilities for discovery, stream tails, LSP batching, and source formatting.
- Consolidated repeated test helpers and fixtures into shared modules, replacing inline helper duplicates.
- Replaced todo_write's `ops` payload with top-level mutation fields (`phases`, `complete`, `start`, `add_notes`, etc.).
- Removed in-place task content and note updates; moved note writes to append-only `add_notes` calls.
- Matched `add_tasks.phase` by phase ID or name and appended new note text to existing notes.
- Changed execution to drop strict in-progress update sequencing, support `start`, and auto-promote next pending task.
- Updated tests and prompt docs to use direct payloads (`phases`, `complete`, `add_tasks`) instead of `ops`.
- Added a guard in AgentSession to detect prior user messages and skip eager todo injection after the initial user turn.
- Updated session tests to assert that only the first user message triggers eager todo enforcement while follow-up prompts do not.
- Documented the behavior change in the package changelog under Unreleased.
- Added `/force` slash command and `ToolChoiceQueue` system for managing tool-choice directives with lifecycle callbacks and requeue semantics.
- Added `setForcedToolChoice()`, `peekQueueInvoker()`, `buildToolChoice()`, `steer()`, and `getToolChoiceQueue()` methods to AgentSession and ToolSession APIs.
- Refactored tool-choice override mechanism from simple override to queue-based system with generator directives, lifecycle callbacks, and requeue preservation.
- Removed `PendingActionStore` class and replaced with `ToolChoiceQueue`; updated `ResolveTool` and custom tool loader to use queue invokers.
- Fixed tool-choice queue cleanup on agent loop abort and requeue semantics to preserve callbacks across abort cycles.
- Eager todo enforcement now skips prompts ending with question marks or exclamation marks, treating them as queries or commands rather than statements requiring task planning.
- Added 2 test cases validating that eager todo enforcement is skipped for prompts ending with question and exclamation marks.
- Added `close()` method to SessionManager and AuthStorage for proper resource cleanup and finalization of prepared statements.
- Added `initiatorOverride` option support in OpenAI and Anthropic providers for message attribution control.
- Fixed resource leaks in RpcClient timeout handling by centralizing timeout creation with unref() and adding explicit clearTimeout() calls.
- Fixed AgentSession disposal to call SessionManager's `close()` method for guaranteed resource cleanup instead of fallback flush.
- Updated all test suites to properly dispose AuthStorage instances in cleanup hooks to prevent resource leaks between tests.
- Changed eager todo reminder message role from 'developer' to 'custom' with customType field for better message categorization.
- Removed userRequest parameter from eager todo prelude generation to simplify prompt template rendering.
- Updated eager todo prompt to avoid redundant todo_write calls unless task state materially changed.
- Modified eager todo reminder message to use string content with display: false property instead of array format.
- Refactored eager todo injection from recursive prompt call to prepended message pattern.
- Removed state fields for todo injection tracking and consolidated logic into message composition.
- Added prependMessages option to promptWithMessage for composing messages before main prompt.
- Updated system prompt to require todo creation before substantive work on user requests.
- Added optional `details` field to TodoItem type for storing implementation specifics, file paths, and edge cases.
- Enhanced todo item display to show multi-line details with automatic indentation in interactive and reminder modes.
- Updated eager-todo system prompt to enforce separation of short task content (5-10 words) from detailed implementation information.
- Extended TodoWriteTool to support creating and updating tasks with details field via add_task and update operations.
- Added comprehensive test coverage for details field handling across todo operations (replace, add_task, update).
- Added 'todo.eager' configuration setting to automatically create a comprehensive todo list after the first user message.
- Added 'buildNamedToolChoice' utility function to build provider-aware tool choice constraints for named tools.

- Extracted tool choice building logic into reusable utility module for better code organization.
- Added comprehensive test coverage for eager todo enforcement functionality in AgentSession.
