- Implemented clipboard register management, parsing, and execution rules for CUT, COPY, and PASTE operations in the hashline engine.
- Added session-persistent clipboard state and integration across agent session execution, diff previews, and streaming tools.
- Added comprehensive validation, error messages, recovery handling, and test coverage for clipboard and block operations.
New live, rebuilt, and transcript-builder assistant components now inherit the active tool-output expansion state before provider errors render.
Added regression coverage for an error arriving after expanded mode was already enabled.
Fixes#6555
computeNonMessageBreakdown estimated Skills tokens from the unfiltered
session.skills registry and subtracted that from the first system-prompt
block, which only ever contained the rendered (filtered) skills. Hidden
explicit-only skills (hide/disable-model-invocation) and all skills when
the read tool was absent inflated Skills and clamped System prompt to 0.
Add a renderedSkills helper mirroring buildSystemPrompt's filter and use
it for the Skills estimate so the category split matches the provider
prompt.
Fixes#6498
- Extracted internal handlers and logic from AgentSession into dedicated runner, guard, and coordinator modules.
- Created standalone modules for bash execution, evaluation runners, IRC bridging, and prewalk coordination.
- Established dedicated session components for tracking stats, todos, streams, and retry fallback chains.
- Preserved existing session behavior while significantly reducing monolithic class size and complexity.
Status presenters (showWarning/showError/showStatus and extension/tool
error presenters) baked theme.fg() into Text at construction, so a
warning shown while the auto-theme default guess was dark kept the
dark-mode color after async appearance detection switched the active
theme to light — dark-catppuccin Mocha yellow on the light Latte
background (1.12:1 contrast, effectively invisible).
Add Text.setStyleFn(), a foreground styler evaluated at render time, and
route the transient status presenters through it. Because the coding
agent invalidates status components on onThemeChange, a theme swap now
re-shapes them against the live theme instead of replaying the palette
active when they were constructed.
Fixes#6337
Preserved settled user and assistant component instances during compaction-only transcript rebuilds so warmed Markdown and layout caches remain valid.
Covered both manual and automatic compaction paths with focused regression tests.
Fixes#6033
Scoped ordinary input frames to the focused component while retaining a full compose when input moves focus. Explicitly repainted the coding-agent pending-message sibling and covered stable focus, wrapped growth, focus movement, and queue clearing.
Fixes#5928
- Added the `xd://` virtual device protocol (`internal-urls/xd-protocol.ts`, `tools/xdev.ts`): tools declaring `loadMode: "discoverable"` are unmounted from the request tools array and driven via `read xd://` (list/docs+schema) and `write xd://<tool>` (execute), gated by the `tools.xdev` setting (default on) and inlined into the system prompt.
- Merged the `irc`, `job`, and `launch` tools into a single `hub` tool (`tools/hub/`, `async/job-manager.ts`): messaging keeps `send`/`inbox`/`list`, job control maps to `wait`/`cancel`/`jobs`, process supervision keeps `start`/`logs`/`stop`/`restart`/`describe` with `ps`, and the unified `wait` races background jobs against peer messages; SDK `IrcTool`/`JobTool`/`LaunchTool` are replaced by `HubTool`.
- Removed the hidden `resolve` tool in favor of the `xd://resolve`/`xd://reject`/`xd://propose` resolution devices, auto-including `write` whenever a deferrable tool or plan mode is present.
- Removed the BM25 tool-discovery system: the `search_tool_bm25` tool, the `tool-discovery` module, the `tools.discoveryMode`/`mcp.discoveryMode`/`mcp.discoveryDefaultServers`/`tools.essentialOverride` settings, per-tool MCP selection, and the `mcp_tool_selection` message type.
- Unified tool presentation on `ToolLoadMode` (`essential`|`discoverable`), replacing the custom-tool `xdev?: boolean` opt-out; custom, extension, MCP, RPC host, image-generation, and TTS tools now default to `discoverable`, and added a `satisfies` predicate to `SoftToolRequirement`.
- Removed the standalone `ssh` command tool and `ssh/ssh-executor` (the `ssh://` read/write/search protocol stays), and made `--tools` address hidden built-ins.
- Updated collab-web to render `xd://` dispatches and `hub` op families, dropped the `search_tool_bm25`/`ssh`/`report-finding` renderers, refreshed tool docs and prompts, and migrated the affected tests and changelogs.
- Normalized completed image_generation_call results into assistant image blocks.
- Persisted image bytes through the session blob store and rendered them in live, replay, ACP, proxy, telemetry, and HTML paths.
- Added response normalization, persistence, and TUI rendering regressions.
Fixes#4768
- Added `StrippedToolCallsMarker` to identify assistant messages with dangling tool calls that were removed during context building.
- Updated `buildSessionContext` to preserve turn entries in transcripts even when all content is stripped, marking them with the count of elided calls.
- Updated `UiHelpers` to render a dim, italicized placeholder in the TUI when an assistant message has elided tool calls, preventing silent activity gaps.
- Updated transcript session context to use display.collapseCompacted setting instead of a hardcoded boolean.
- Enabled user-defined control over whether compacted history is collapsed during live rendering sessions.
- Implemented `/queue` command and `->`/`=>` shorthands to support deferred, sequential message processing.
- Added a robust parsing utility to handle various list-based queue inputs and automate yield management.
- Integrated visual decorations and state tracking to provide real-time feedback on queueing status.
- Enabled non-cursor line text decoration in the TUI to support dynamic queue header rendering and list numbering.
- Enabled persistence of dangling tool calls during transcript rebuilds by adding `keepDanglingToolCalls` configuration.
- Integrated `seal()` logic for pending tool blocks to properly finalize history during idle session states.
- Enhanced UI helpers and session context to preserve assistant turns during streaming or mid-turn rebuilds.
- Added comprehensive unit and integration tests to verify correct tool call tracking and transcript integrity.
- Split mixed assistant text into per-tool segments instead of one post-tool tail.
- Insert each segment immediately after its preceding tool component across live and rebuilt transcripts.
- Extended the regression test to cover two tool calls with middle and final assistant text.
Fixes#4871
- Split mixed assistant messages so pre-tool text stays before tool panels while trailing text renders after the tool timeline.
- Applied the split to live streaming, transcript rebuilds, and file-backed transcript rendering.
- Added a focused EventController regression test for text/toolCall/text Cursor-shaped turns.
Fixes#4871
The token-usage row shown under assistant messages (display.showTokenUsage) now leads with the turn's local wall-clock time down to the second (YYYY-MM-DD HH:mm:ss), sourced from the assistant message's persisted timestamp so live, rebuilt, and restored transcripts all show the turn time rather than the view time.
createUsageRowBlock takes timestamp as an optional trailing argument, preserving its (usage, durationMs, ttftMs) public call contract on the package's ./modes/components/* export surface.
computeNonMessageTokens / computeNonMessageBreakdown re-tokenize the system
prompt and every tool's wire schema (per-tool JSON.stringify) on each call,
but the per-turn compaction and context-threshold paths call them several
times (getContextBreakdown twice, #estimateStoredContextTokens once) over
inputs that change at most once per turn. Memoize on the identity of
(systemPrompt, tools, skills) -- the same stable refs the StatusLineComponent
cache already trusts -- so the expensive parts run at most once per input
change instead of per call.
Stopped new-session and session-switch UI paths from detaching active loader/render components without running their disposal hooks.
Added container and loader coverage for disposing children before destructive transcript/status replacement.
Fixes#4686
Replace the visible-anchor suppression with a billed-usage predicate so live and resume paths agree on rendering the badge whenever the turn actually consumed tokens. Only genuinely free turns (no input, output, cache, or premium requests) drop the row, so hidden automated turns keep cost transparency.
Fixes#4532
Suppress token-usage rows for assistant turns that have no visible text, tool call, or terminal error anchor. Share the same decision across live rendering and transcript rebuilds so resume matches live output.
Fixes#4532
- Enforced strict history protection by gating ephemeral block removal on uncommitted state across controllers and UI components.
- Optimized settled-row calculations using explicit mermaid fence detection and improved scrollback integrity.
- Refactored transience management to target only actively streaming blocks, preventing redundant label rendering.
- Implemented persistent compaction for auto-retry errors and enabled consistent terminal title updates during session renaming.
- Refactored abort reason handling to rely on shouldRenderAbortReason instead of isSilentAbort.
- Updated documentation to clarify that both silent and user-interrupt aborts yield no label.
- Introduced an automated retry recovery system to track, manage, and persist recovered error states within agent sessions.
- Enabled compact transcript rendering for recovered auto-retry errors by removing heuristic commit machinery.
- Improved raw read tracking and provenance in the ReadTool to support refined file snapshot recording and hashline editing.
- Excluded recovered assistant messages from default model context and updated event controllers to handle retry recovery life cycles.
- Extracted decodeStreamedToolArgs into tool-args-reveal.ts and used it from both the live event path and transcript rebuilds, so mid-write theme/settings/focus replays no longer show stale streamed write/edit/eval content.
- Fixed the smoothing-off live path returning stale provider-parsed args.
- Documented the mandatory shared decode in the AGENTS.md streaming-preview hazard note; added changelog entries for this batch.
- Introduced `isProbablyBinary` utility to sniff file headers for NUL bytes or invalid UTF-8 sequences.
- Updated `ReadTool` to use the binary sniffer, preventing mojibake corruption in output when reading non-text files.
- Refined `file-mentions` auto-reads to skip binary files and mark them as `binary` in the message transcript.
- Added comprehensive unit tests for binary detection logic, covering NUL bytes, truncated multibyte characters, and path-based file sniffing.
- Migrated internal streaming state from string-based properties to symbol-keyed properties for improved data isolation and safety.
- Replaced the deprecated `stripVariant` utility with centralized `clearStreamingPartialJson` and symbol-specific helper methods across all provider implementations.
- Implemented `stripStreamingBlockSymbols` and updated deep equality checks to ensure metadata does not interfere with content comparisons.
- Standardized streaming metadata access through a new `block-symbols` utility module.
- Migrated 288 lines of scattered error classification logic from `utils/error-id.ts` into a cohesive `packages/ai/src/error/` module with 13 specialized submodules covering flags, classes, OAuth, providers, rate-limiting, and finalization.
- Replaced 100+ generic `Error` throws across 60+ provider and registry files with semantic `AIError.*` classes (e.g., `AIError.MissingApiKeyError`, `AIError.OAuthError`, `AIError.ProviderResponseError`), improving error diagnostics and retry logic.
- Consolidated error utility imports from `pi-utils` and scattered classification functions into a single `AIError` namespace, reducing coupling and simplifying error handling across all packages.
