- Converted systemPrompt APIs and state types to ordered `string[]` across agent, AI, and coding-agent surfaces.
- Added `normalizeSystemPrompts` and applied it to context normalization before building provider request payloads.
- Updated AI providers to emit separate normalized prompt blocks/messages instead of a single merged system prompt.
- Removed dedicated `projectPrompt` state and remapped that context into system-context buckets in session, dump, and token accounting.
- Aligned tests and changelogs to pass and assert `systemPrompt` as arrays with ordered prompt semantics.
- Renamed subagent completion flow from `submit_result` to `yield` across SDK tools, prompts, and docs.
- Updated executor/task handling to require and parse `yield` calls, replacing legacy submit-result extraction and state flags.
- Added `subagent-yield-reminder` and updated system prompts to require `yield` with `result.data` or `result.error`.
- Renamed hidden-tool and registration plumbing to `yield`, including discovery helpers and renderer/test surface.
- Fixed memory leak by cancelling idle compaction timer on event controller disposal.
- Fixed session resumption to preserve last non-empty session when starting fresh.
- Fixed stash detection to use git ref resolution instead of output parsing for reliability.
- Fixed secret obfuscation to deobfuscate restored session messages locally while keeping LLM messages obfuscated.
- Fixed stash pop operation to preserve staged changes with --index flag after task branch merges.
- Changed idle compaction settings from enum to numeric type for flexible configuration.
Wire EventBus through task runtime so subagent lifecycle and progress
events propagate to the TUI. Add SessionObserverRegistry to track
active sessions, and a session observer overlay accessible via Ctrl+S
that shows a picker of running subagents and a read-only transcript
viewer that reads the subagent's session JSONL file to display
thinking, text, tool calls, and results.
- Add TASK_SUBAGENT_LIFECYCLE_CHANNEL for start/end events
- Add SubagentProgressPayload.sessionFile for session file tracking
- Pass eventBus through sdk.ts -> main.ts -> InteractiveMode
- SessionObserverRegistry with multi-listener onChange pattern
- Overlay picker preserves selection position across live refreshes
- Viewer renders full transcript from session JSONL (thinking, text,
tool calls with smart arg summaries, inline tool results)
- Extracted OpenAI compatibility detection and resolution logic into dedicated `openai-completions-compat` module.
- Refactored `detectCompat()` and `getCompat()` to delegate to new compat module functions with simplified conditional logic.
- Fixed OAuth redirect URI validation to preserve exact configured values without trailing slash normalization.
- Improved session deletion to return boolean status and display error messages in UI instead of silently failing.
- Added `/session delete` command with Delete key support and confirmation dialogs for session management.
- Added `attribution` option to `PromptOptions` for controlling billing and initiator attribution.
- Updated subagent prompts to explicitly set `attribution: "agent"` for accurate billing attribution.
- Refactored message attribution logic to use configurable `promptAttribution` with fallback defaults.
- Added test coverage for `attribution` option in subagent reminder prompts.
Fixes#439.
feat(coding-agent): added attribution option and explicit session directory control
- Added `attribution` option to `PromptOptions` for explicit billing and initiator attribution control.
- Updated `SessionManager.create()` to require both `cwd` and `sessionDir` parameters for explicit session directory control.
- Changed session directory naming for temporary working directories from `--` format to `-tmp-` prefix.
- Made `cwd` and `sessionDir` fields mutable in SessionManager to support session relocation.
- Fixed automatic migration of legacy session directories to new `-tmp-` prefixed naming scheme.
- Updated all test fixtures to pass both `cwd` and `sessionDir` parameters to `SessionManager.create()`.
- Added task model role configuration enabling dedicated subtask execution with independent model selection.
- Changed default agent model from 'default' to 'pi/task' for independent subtask model configuration.
- Added single-pattern inheritance fallback allowing pi/task agents to inherit session model when unconfigured.
- Refactored model resolution logic into resolveAgentModelPatterns() function with structured fallback handling.
- Added resolveConfiguredModelPatterns() and helper functions for improved model pattern resolution.
- Introduced Effort enum and ThinkingConfig metadata for per-model reasoning capabilities with min/max effort levels.
- Migrated thinking level API from string-based ThinkingLevel to structured Effort enum across agent and AI packages.
- Added model-thinking module with effort mapping, policy application, and semantic versioning utilities for provider-specific thinking modes.
- Removed supportsXhigh() function and replaced effort clamping with model-aware validation using ThinkingConfig metadata.
- Expanded models.json with thinking configuration objects for 50+ models including Claude, Gemini, and OpenAI variants.
- Added Python analysis scripts for edit tool usage patterns and tool invocation stream processing.
- Add a dedicated abortReason field to SingleResult and thread it through task execution paths so aborted subagents show actionable context instead of a generic badge.
- Populate abortReason for signal cancellation, pre-start cancellation, submit_result aborted status, and missing submit_result after reminders
Fixes#248
- Added public `waitForIdle()` and `getLastAssistantMessage()` APIs to AgentSession for deterministic session state access.
- Refactored deferred continuation scheduling from raw `setTimeout()` to centralized post-prompt task tracking system for concurrent recovery operations.
- Fixed race conditions between deferred TTSR/context-promotion continuations and `prompt()` completion via shared recovery orchestrator.
- Replaced `#waitForRetry()` with `#waitForPostPromptRecovery()` to unify retry and TTSR resume gate handling.
Validate report_finding details before extraction and normalize findings before task rendering to avoid crashes when tool errors emit empty details.
Fixes#173
- Fixed submit_result tool to only terminate on successful execution instead of always terminating.
- Removed deferred termination logic and simplified abort behavior to call requestAbort immediately.
- Added submitResultCalled flag tracking to properly manage tool execution state.
- Added test coverage for submit_result tool retry behavior after execution errors.
- Exported `finalizeSubprocessOutput()` function and `SubmitResultItem` interface for subprocess output finalization with submit_result validation.
- Added automatic reminders (up to 3) when subagent stops without calling submit_result tool, aborting with exit code 1 after final reminder.
- Extracted subprocess output finalization logic into dedicated `finalizeSubprocessOutput()` function for improved testability and reusability.
- Added comprehensive test coverage for subagent warning injection, reminder behavior, and abort handling in executor module.
