## 1. ToolCallDecision — capture thinking and text output

- [x] 1.1 Add `thinking: str | None = None` and `text_output: str | None = None` fields to `ToolCallDecision` in `runtime/tool_calling_client.py`
- [x] 1.2 Update `_decision_from_anthropic_response()` to iterate all content blocks: collect first `thinking`-type block text into `thinking`, concatenate all `text`-type blocks into `text_output`, continue to `tool_use` as before
- [x] 1.3 Update `_decision_from_openai_response()` to extract `reasoning_content` from the first choice's message into `thinking` when present
- [x] 1.4 Add unit tests: Anthropic response with thinking block → `decision.thinking` populated; Anthropic response with text block → `decision.text_output` populated; response with only `tool_use` → both `None`; OpenAI response with `reasoning_content` → `decision.thinking` populated

## 2. PlannerConfig — extended thinking configuration

- [x] 2.1 Add `thinking_budget_tokens: int | None = None` to `PlannerConfig` in `runtime/planner_config.py`
- [x] 2.2 Add `AI_PLANNER_THINKING_BUDGET_TOKENS` env var constant and `_parse_thinking_budget()` helper; wire into `load_config()`
- [x] 2.3 Update `AnthropicToolCallingClient._create_message()`: when `thinking_budget_tokens` is set, add `thinking: {type: "enabled", budget_tokens: N}` to kwargs, add `interleaved-thinking-2025-05-14` beta header via `betas` parameter, and enforce `max_tokens >= thinking_budget_tokens + 1`
- [x] 2.4 Add unit tests: `load_config()` with env var set → `thinking_budget_tokens` parsed; `_create_message()` with budget set → kwargs include thinking param and beta header; without budget → no thinking param in kwargs

## 3. PlannedStep — carry rationale and thinking

- [x] 3.1 Add `rationale: str | None = None` and `thinking: str | None = None` to the `PlannedStep` dataclass in `runtime/planner.py`
- [x] 3.2 Update `AIPlanner.plan()` in `runtime/ai_planner.py`: populate `PlannedStep.rationale = decision.text_output` and `PlannedStep.thinking = decision.thinking`

## 4. Planner prompts — reflection instruction

- [x] 4.1 Update `PLANNER_SYSTEM_PROMPT` in `runtime/planner_prompts.py` to instruct the AI to output a short text block (1–2 sentences) before each tool call: first assessing whether the previous action achieved its intended effect (or noting "first step" if no history), then stating the intent of the current action
- [x] 4.2 ~~Verify via prompt review that the instruction is consistent with `tool_choice: {type: "any"}` (text blocks are already allowed before tool_use blocks — no API change needed)~~ — **superseded, see section 9**: this assumption was wrong; forced `tool_choice` suppresses text/thinking entirely

## 5. History format — compact rationale-based representation

- [x] 5.1 Update `_history_summary()` in `runtime/ai_planner.py` to return compact dicts `{page, rationale, action, success}` instead of `[event.to_dict() for event in world.history]`
- [x] 5.2 Add unit test: `_history_summary()` with a populated `WorldState` returns list of compact dicts without scene element data

## 6. WorldEvent — rationale, thinking, page fields

- [x] 6.1 Update `WorldEvent` in `world/models.py`: make `scene_summary` optional (`SemanticScene | Scene | None = None`), add `rationale: str | None = None`, `thinking: str | None = None`, `page: str | None = None`
- [x] 6.2 Update `WorldEvent.to_dict()` to include `rationale`, `thinking`, `page` fields; keep `scene_summary` serialisation for backward compatibility
- [x] 6.3 Update `WorldModel._append_history()` in `world/model.py` to pass `rationale=step.rationale`, `thinking=step.thinking`, `page=world_state.current_page` when constructing `WorldEvent`; `scene_summary` becomes optional (pass `None` or existing value as appropriate)
- [x] 6.4 Add unit tests: `WorldEvent` with rationale/thinking/page → `to_dict()` includes those fields; `WorldEvent` with all-None optional fields → readable without error; `_append_history()` picks up `current_page` from `WorldState` at time of call

## 7. Cloud DB — planner_decision_log extension

- [x] 7.1 Add `thinking` and `rationale` nullable TEXT columns to the `planner_decision_log` table in `packages/cloud-platform/cloud/db_models.py`
- [x] 7.2 Create a new Alembic migration (e.g. `0010_planner_decision_log_reflection`) adding the two nullable columns; verify it applies cleanly on both SQLite and PostgreSQL migration paths
- [x] 7.3 Add `thinking: str | None = None` and `rationale: str | None = None` to `PlannerDecisionRecord` in `packages/cloud-platform/cloud/internal_api/models.py`
- [x] 7.4 Update `record_planner_decision()` in `packages/cloud-platform/cloud/internal_api/api.py` to write `thinking` and `rationale` from the incoming `PlannerDecisionRecord` to the new columns
- [x] 7.5 Add unit tests: decision record with rationale/thinking → both stored; decision record with nulls → stored without error; existing rows queried → both columns read as NULL without error

## 8. End-to-end verification

- [x] 8.1 Run full non-integration test suite (`uv run --all-packages pytest -m "not integration"`) and confirm no regressions
- [x] 8.2 Run `ruff check` and `ruff format --check` on all modified files
- [x] 8.3 Run `python -m compileall` on modified packages
- [x] 8.4 Run `openspec validate --strict --change "planner-reflection-history"` and confirm all artifacts pass validation
- [x] 8.5 Manual smoke test (requires Host Agent + Appium + iPhone): ran a live task and found `rationale`/`thinking` were **always** `None` in `WorldEvent` history — root cause diagnosed and fixed in section 9 below

## 9. Bug fix — forced `tool_choice` was suppressing rationale/thinking (found via 8.5)

- [x] 9.1 `AnthropicToolCallingClient._create_message()`: add required `forced: bool` param; `tool_choice` is `{"type": "auto", "disable_parallel_tool_use": True}` when `forced=False`, `{"type": "any", "disable_parallel_tool_use": True}` when `forced=True`; thinking/`betas` kwargs only added when `forced=False`
- [x] 9.2 `AnthropicToolCallingClient.decide()`: call with `forced=False` first; if `_anthropic_response_has_tool_use(response)` is `False`, retry once with `forced=True`; parse whichever response has the tool call
- [x] 9.3 `OpenAIToolCallingClient._create_completion()`: add required `forced: bool` param; `tool_choice` is `"auto"` when `forced=False`, `"required"` when `forced=True`
- [x] 9.4 `OpenAIToolCallingClient.decide()`: same auto-then-forced-retry pattern using `_openai_response_has_tool_call()`
- [x] 9.5 `_decision_from_openai_response()`: extract `message.content` into `text_output` (previously never captured for OpenAI, forced or not)
- [x] 9.6 Add/rename unit tests in `tests/test_tool_calling_client.py` covering: default request uses `tool_choice: "auto"`; retry sequence when first response has no tool call (Anthropic and OpenAI); thinking/`betas` dropped on the forced retry; OpenAI `text_output` capture
- [x] 9.7 Update `design.md` (D1 correction + new D8) and this file to document the bug and fix
- [x] 9.8 Re-run `uv run --all-packages pytest -m "not integration"`, `ruff check`/`ruff format --check`, `python -m compileall`, and `openspec validate --strict --change "planner-reflection-history"` after the fix

## 10. Required reusable action metadata (post-completion amendment)

- [x] 10.1 Require `purpose` and `expected_outcome` in every device-action tool schema; extract them from executable arguments into `ToolCallDecision` and `PlannedStep`.
- [x] 10.2 Return rationale, thinking, purpose, and expected outcome through the Cloud planner response; persist the new action metadata in `planner_decision_log` with an additive migration and expose it through the task decision API.
- [x] 10.3 Preserve executable arguments, purpose, and expected outcome in `WorldEvent`, Timeline records, and synthesized `FlowStep` values; include available metadata in skill embedding text for semantic retrieval.
- [x] 10.4 Render available rationale, thinking, purpose, and expected outcome in Cloud Console planner-decision history.
- [x] 10.5 Add focused regression tests and run the relevant Python, frontend, migration, lint/format, and OpenSpec validation checks.
