- Added explicit ArkType schema descriptions across all coding agent tool definitions.
- Updated schema definitions in autoresearch and commit tools with descriptive wrappers.
- Documented tool schema enhancements in the packages/coding-agent CHANGELOG.
- Migrated all wire protocol, schema definitions, and tools validation from Zod to ArkType across multiple packages.
- Updated extension runtimes, custom tools loader, and TypeBox compatibility shim to expose and use ArkType instances.
- Added a comprehensive ArkType migration guide, validation parity tests, and helper utilities.
- Removed redundant PDF asset routing and parsing implementations from the read tool.
- Added a list-mode flag to job rendering and used it to keep background job listing behavior distinct.
- Filtered non-partial poll call results to exclude running jobs and return no output when only running jobs remain.
- Added tests covering partial rendering, poll-based filtering, and list/cancel paths for the updated preview behavior.
- Added an `interruptible` field to AgentTool and documented when it is honored.
- Updated immediate-mode tool execution to poll steering during in-flight interruptible calls and abort them when steering is queued.
- Marked the coding `job` tool as interruptible and added tests covering mid-wait aborts versus boundary-only steering drain.
- Added a smart poll-wait mode to AsyncJobManager with per-owner escalation ladder logic and a reset timer for idle pauses.
- Updated job polling to use the adaptive wait when `async.pollWaitDuration` is `smart` and to record poll completion timing for subsequent waits.
- Expanded async job settings and tests so `smart` is the default option and escalation, reset, and owner isolation behavior are covered.
- Added optional `useless` flags to tool result types and payload builders.
- Added `pruneUseless` and `dropUeless` options to control uneventful result pruning.
- Changed compaction and shake passes to prune or ignore non-error useless tool results.
- Changed conversation serialization to omit useless toolCall/toolResult pairs from output.
- Added coverage for useless tagging, pruning, and serialization behavior.
- Added `packages/collab-web/src/tool-render/`: a per-tool React renderer suite (one view per built-in tool) with common `ToolView` chrome, a `tv-` CSS design system, a registry, and an `<omp-tool-view>` web-component wrapper (`element.tsx`, `standalone.tsx`).
- Switched collab-web transcript `ToolCard` to the per-tool renderers instead of the generic args/result JSON dump, and threaded a `ToolRenderHost` through `Transcript`/`AgentDrawer`/`app.tsx` so task-card agent chips drill into the matching subagent drawer.
- Added `scripts/build-tool-views.ts` plus the `build:tool-views` script bundling the renderers (React included, `</script` escaped) into the gitignored `coding-agent/src/export/html/tool-views.generated.js`.
- Modernized the coding-agent HTML export chrome in `template.html/css/js` to the tool-card design language and added the `<template-tool-views/>` injection point.
- Showed the standard done checkmark for completed rows in the `job` tool renderer; its changelog line shares a changed run with the restyle entries.
- The session-operations doc gained two adjacent lines; the subagent-transcript one belongs to the upcoming /share commit but is inseparable from the tool-view line.
- Changed collapsed progress rendering to keep the most recent live agents visible, adding a summary line for folded-away rows.
- Updated collapsed result rendering to preserve failed and aborted agents in the visible set while trimming other completions.
- Refreshed job polling text to document waiting on all running jobs when `poll` is omitted and added tests for both collapsed progress and result display behavior.
- Detached async task progress rows stopped running a redraw driver and task progress rendering switched running/pending rows to static task-icon text.
- Background task snapshots were frozen once blocks left the transcript live region, preventing later partial snapshots from repainting commit-eligible rows.
- Updated task-progress and detached-background-task tests to validate static task rows and the new freeze behavior.
- Running job labels now shimmer in the TUI to provide a dynamic visual indicator of activity.
- Adjusted cache key to account for shimmer animation, ensuring it updates at 30fps instead of the 12.5fps spinner cadence.
- Suppressed job ID display when the job label is identical to its ID, avoiding redundant information.
- Removed the running count from the status meta list so only completed, failed, and cancelled counts are shown.
- Updated the waiting message to use singular/plural job labels and simplify wording when all jobs are running.
- Replaced task-simple-mode with a `task.batch` setting enabled by default.
- Updated task schema to use batch `{agent, context, tasks[]}` payloads.
- Migrated task execution to spawn one async job per task and merge outputs.
- Removed per-call schema passing while preserving legacy flat task calls.
- Added a helper to strip model-facing `<task-result>` wrappers from job result text.
- Updated the job tool renderer to preview the unwrapped `<output>/<preview>` body instead of the envelope markup.
- Documented the settled-task preview fix in the coding-agent changelog.
A job poll whose watched jobs are all still running and nothing was cancelled is pure 'still waiting' noise once a newer block exists. ToolExecutionComponent now detects isWaitingPollDetails on the result, leaves the block displaceable, and keeps its rows out of scrollback. EventController tracks the most recent displaceable poll and resolves it (sealing the block) on every event that proves another tool now owns the live region: a new tool call/result, a streaming arg start, an end-of-turn signal, or another job result that itself isn't displaceable. UiHelpers' transcript rebuild applies the same rule. Docs and the new job-poll-displacement test pin the behavior.
Removes isBackgroundJobSupportEnabled and JobTool.createIf; the tool is now registered unconditionally via `new JobTool(s)`. `async.enabled` now gates async bash commands only — the task tool runs asynchronously regardless. Deletes the async/support module and its barrel re-export.
- Added status.done and tool.* symbols to theme mappings and presets.
- Replaced generic success glyphs with contextual +/-, tool icons, and warnings.
- Mapped tool/task/job completions to status.done or status.enabled with icon overrides.
- Triggered runtime provider refresh after extension registration and warned on failure.
- Unified edit, ask, ast-edit, todo, write, and inspect outputs using framedBlock.
- Wrapped failure and warning cases in framed blocks with clearer status states.
- Standardized frame body rendering by trimming blank lines and clipping content width.
- Simplified tool execution layout by removing dynamic padding and background helpers.
Per PR review on #1926: a secondary in-process top-level createAgentSession() that exposes bash/task/job tools would still call AsyncJobManager.instance() at execute time, register on the primary's manager, and have the primary's onJobComplete enqueue results into the primary's yieldQueue — corrupting the owning session's conversation.
ToolSession now carries an asyncJobManager reference scoped to its session: the constructed manager for top-level sessions, the inherited singleton for subagents (so their bash/task completions still flow into the spawning conversation as before), and undefined for secondary in-process top-level sessions that found a singleton already installed. bash, task, and job tools resolve the manager through ToolSession instead of the process-global singleton, so a secondary session whose tools attempt async work fails fast with the standard "Async job manager unavailable" error instead of contaminating the primary.
