- Add `onFirstChatDispatch` hook to `CreateAgentSessionOptions` to track the boundary between session creation and the initial model request.

- Added an early return to stop event propagation if no handlers are registered for the event type.
- Updated the `agent_start` logic to return early, ensuring consistent flow control.
- Introduced a "[NEW]" marker in tip text that triggers an animated rainbow-colored tag in the welcome component.
- Implemented `renderNewTag` to calculate cyclic HSL hue offsets based on render timing.

- Resolved provider-specific 400 errors for OpenRouter and GLM models by refining reasoning effort mapping and retry logic.
- Standardized credential management in both the coding-agent and model catalog by migrating to the unified authentication broker.
- Updated the system schema and prompt options to disable inline tool descriptors by default.
- Modified the build system prompt logic to reflect the new default fallback value.
- Export `directoryExists` in `utils` to safely validate working directories before traversal.
- Update `SessionManager` and startup logic to fallback to the launch directory if a session's recorded working directory no longer exists.

- Add `directoryExists` check to validate session working directories.
- Skip updating the session cwd if the recorded directory no longer exists on disk to prevent runtime errors.
Skip the secondary loadSystemPromptFiles capability walk when the caller already controls block 0 via customPrompt/resolvedCustomPrompt, so project/user SYSTEM.md cannot silently augment a CLI --system-prompt override.
Fixes#3014
- Add a check requiring `cacheWrite > 0` to identify meaningful cache invalidation.
- Prevent false positives for providers with implicit caching that intermittently report zero reads without a fresh cache write.
- Add regression test case to verify implicit providers are not flagged as invalidations.
- Replaced four individual power boolean settings with a single `power.sleepPrevention` enum for improved configuration management.
- Implemented automatic migration logic in `Settings.init` to map legacy macOS power booleans to the new enum levels.
- Updated `AgentSession` to utilize the new `sleepPrevention` enum for macOS power assertion lifecycle management.
- Changed default value of `display.cacheMissMarker` to `false` to suppress cache-miss markers.
- Added comprehensive unit tests in `settings-manager.test.ts` to verify backward-compatible migration behavior.
- Accepted client/registerCapability and client/unregisterCapability server requests so Expert can continue startup before semantic requests.\n- Allowed JSON-RPC string ids on LSP request/response handling.\n- Added a regression test for dynamic registration gating hover.\n\nFixes #3029
Added an advisorEnabled visibility predicate and wired the advisor dependent settings through it so the Model Advisor sub-options hide unless Enable Advisor is active. Added regression coverage for the settings UI adapter.\n\nFixes #3027
- Added tracking for expected cache invalidations during model changes, compactions, and plan-mode transitions.
- Included `cacheMissExplainedAt` metadata in session context to prevent displaying misleading cache miss warnings in the transcript.
- Updated controller logic to reset assistant usage markers when mode-switching or performing actions that invalidate the prompt cache.
- Renamed `repeatToolDescriptions` to `inlineToolDescriptors` throughout configuration, SDK, and internal session management.
- Set the default value to `true` and updated descriptions to clarify the descriptor inlining behavior.
- Fixed the `/dump` command to prevent duplicate tool inventory output when inlining is enabled.
- Switch all UI components and tests from sharp box corners (`boxSharp`) to rounded ones (`boxRound`).
- Update `Theme` to re-export sharp junction symbols (tees and cross) under `boxRound` to ensure consistent divider rendering in rounded boxes.
- Remove outdated architectural notes regarding forced tool-choice queues in documentation.
- Added `display.cacheMissMarker` setting to enable visual indicators for prompt cache invalidation in assistant messages.
- Included updated theme symbols to represent cache misses across supported icon sets.
- Configured the selector controller to rebuild the chat display when the marker visibility setting is toggled.
- Introduced `SoftToolRequirement` to support non-invasive tool enforcement with lifecycle management and escalation.
- Added `ToolChoiceDirective` to coordinate hard and soft tool requirements within the agent loop.
- Optimized preview workflows in `coding-agent` by replacing forced tool choices with non-forcing pending invokers.
- Enhanced `CompactionSummaryMessage` to prioritize structured rendering for tool requirement reminders.
- Implemented `detectCacheInvalidation` to identify when model requests lose their prompt cache.
- Added `CacheInvalidationMarkerComponent` to display a slim notice above affected assistant turns.
- Updated `ChatTranscriptBuilder` and `EventController` to track session usage and inject markers dynamically.
- Included comprehensive test coverage for invalidation detection logic and UI rendering.
- Removed legacy `pinnedFrames` logic and state, simplifying compaction to unconditionally re-render from the full source archive.
- Updated `historyBlocks` to reliably order archive regions (text head, imaged middle, text tail) based on the re-rendered state.
- Updated documentation and summary templates to reflect the transition to text-first compaction and the use of the new `FILES` section.
- Refreshed all injected message frames with a consistent rounded-outline card design.
- Implemented icon-tagged headers for hooks, local skill invocations, and generic custom messages.
- Updated skill invocation cards with home-shortened paths, dynamic line count units, and compact invocation argument display.
- Unified branch summary styling with compaction banners to provide a consistent visual language for history collapse points.
- Removed leaked absolute home directory paths from skill metadata displays.
- Added a test asserting `obfuscate` produces byte-identical output when re-run over the same content across turns, the invariant that keeps obfuscated history prompt-cache-stable.
- Added a test asserting earlier-message placeholders stay stable when a later message reveals a new regex-discovered secret.
- Changed `wrapSteeringForModel` to wrap every `steering:true` user message regardless of position, so a steer's wire bytes stay identical once buried instead of reverting to raw and busting the prompt cache.
- Neutralized the present-tense framing in `user-interjection.md` so always-wrapping no longer leaves stale "current task" wording on buried interjections.
- Updated `session-messages.test.ts` to assert buried steering messages are wrapped too.
- Added `keepBoundaryId` and `cacheWarmSuffixTokens` guards to `pruneToolOutputs` and `pruneSupersededToolResults` so superseded/useless results sitting in the already-sent cached prefix are no longer rewritten mid-session, with new `computeMessageSuffixTokens`/`resolveBoundaryIndex` helpers.
- Added a `keepBoundaryId` floor to `collectShakeRegions` so shake skips entries summarized away by the latest compaction.
- Threaded `firstKeptEntryId`, `PRUNE_CACHE_WARM_SUFFIX_TOKENS` (8k) and `PRUNE_IDLE_FLUSH_MS` (90m, above the 1h cache TTL) from `#pruneToolOutputs`, `#pruneStaleToolResults` and `shake` in `agent-session.ts`.
- Added six boundary tests in `supersede-prune.test.ts` covering warm-prefix protection, tail-case pruning, and the pre-boundary floor.
- Added utility functions to strip descriptions from JSON schemas and tool definitions for optimized token output.
- Integrated `pruneToolDescriptions` configuration across agent loops and sessions to enable optional schema pruning.

- Verified schema structural integrity and removal of annotation descriptions through new unit tests.
- Update `MAX_FRAMES_DEFAULT` to 80 to better utilize high-capacity model context windows.

- Added lifecycle management to `ttsr-cli.test.ts` to ensure temporary directories are created once per test run and cleaned up automatically.
- Updated file generation paths in CLI and reproduction tests to prevent local state pollution.
- Moved the `INTENT_FIELD` constant from `@oh-my-pi/pi-agent-core` to the specialized `@oh-my-pi/pi-wire` package to permit broader usage across the monorepo.

- Added `@oh-my-pi/pi-wire` as a dependency to all affected packages.
- Removed the fixed 24-column truncation cap for argument preview values.
