- Added optional since/until/dateField parameters to issue, PR, commit, and repo search tools.
- Added parsing for relative and ISO date bounds and built inclusive/exclusive/range search qualifiers.
- Allowed issue/PR/commit/repo searches to proceed with only date ranges and no query string.
- Mapped tool-specific date fields (commits, repos) and rejected since/until for code search validation.
- Updated search tool docs and tests for date filter formats, mappings, and unsupported-code-search behavior.
- Added ownerId metadata to async jobs and to task/bash progress items from the session agent id.
- Extended async job registration and query methods with optional owner filters, and updated cancelAll to target matching owners.
- Updated session handoff and disposal so subagents inherit the parent manager, top-level sessions own it, and teardown cancels own jobs only.
- Added owner-aware async-job tests using hold/AbortSignal and scoped cancelAll assertions for running versus cancelled jobs.
- Passed the `irc.enabled` session setting into task prompt rendering so templates can branch for IRC mode.
- Updated orchestrator and subagent-task prompts with IRC-specific instruction paths for skip-all checks, coordination, and file-scoped assignments.
- Removed the JS and Python eval prelude `run` helpers, including their shell execution and timeout/cwd option handling.
- Updated the JS VM helper set to expose `Bun` and removed the deleted `run` entry from the prelude.
- Revised eval docs to drop `run` from the helper surface and note the new JS `Bun` global.
- Added parent-to-subagent artifact manager adoption so subagents reuse the parent `ArtifactManager` and write artifacts into a shared directory with shared IDs.
- Passed the shared artifact manager through tool/session context into subagent executor startup and exposed it via `SessionManager` and `ToolSession` for lookup.
- Updated kernel environment and artifact-resolution paths to prefer `PI_ARTIFACTS_DIR`, falling back to existing session-file-based behavior when absent.
- Added process-wide singleton instances for InternalUrlRouter, AsyncJobManager, and MCPManager.
- Changed internal URL protocols to resolve through registered sessions and scan all active roots/datasets for matches.
- Refactored agent, artifact, memory, rule, skill, jobs, and mcp handlers to use shared manager and rule/skill state.
- Removed per-session protocol/tool wiring and switched tests to initialize and reset global singleton state.
- Stored a failure counter during single-path edit execution and set isError on aggregate results when any entry edit failed.
- Set streaming-edit handling to always evaluate auto-generated-file checks, but only primed the file cache when edit.streamingAbort was enabled.
- Added helpers to stringify and truncate display() JSON values before including them in text responses.
- Updated eval execution to append formatted display output text alongside stdout and emit images as dedicated content blocks.
- Adjusted no-output messaging for image-only runs and removed detail-level image payload duplication when content already includes image blocks.
- Updated bash, job, and task prompts to state that background results are delivered automatically when complete.
- Removed guidance encouraging repeated `jobs://` polling and clarified `job` with `poll` should be used only when a task is blocking.
- Changed the bash tool confirmation message to recommend doing other work while waiting for background jobs and polling only if needed.
- Set `minimumReleaseAge` to 259200 in the root `bunfig.toml` install configuration.
- Applied the same `minimumReleaseAge` setting to `packages/coding-agent/bunfig.toml` to enforce a 3-day minimum dependency release age.
- Updated addMessageToChat in UI helpers and InteractiveModeContext to return rendered components instead of void.
- EventController now tracks IRC message components and removes them after a 10-second TTL, avoiding duplicate expiry scheduling per message signature.
- EventController dispose now clears all pending IRC expiry timers and tests were added for immediate render, TTL removal, duplicate suppression, and timer cleanup.
- Removed the shared date, workspace, and critical-response block from now-prompt.md.
- Added the same instructional block to project-prompt.md so the project prompt now carries those system constraints.
- Skipped writing compact conversation context files when IRC is enabled so subagents avoid using stale markdown snapshots.
- In runSubprocess, passed an undefined context file for IRC-enabled paths and kept context file prompting for non-IRC executions.
- Added edit streaming fallback data to the edit render context and used it when no finalized patch text was available.
- Implemented hashline fallback rendering that strips envelope syntax, sanitizes text, and truncates output to a fixed number of lines with a streaming indicator.
- Updated tool execution to populate the fallback preview from the active edit strategy and added a renderer test for hashline envelope input while the diff is not yet computable.
- Added PTY flags to ShellRunOptions and ShellExecuteOptions and defaulted pty to false when unset.
- Routed PTY-enabled shell runs to a dedicated PTY runner and executed commands via `sh -lc` in a PTY.
- Handled PTY output with a dedicated thread, Chunk/Done events, child PGID cancellation, and drain-timeout cleanup.
- Added Unix-only PTY assertions and non-Windows native coverage for `executeShell` with `pty: true` and `/dev/` output checks.
- Added `portable-pty = "0.9"` (and lockfile update) to enable PTY execution in pi-shell.
- Updated the orchestration prompt to require that each `task` instructs subagents to skip all verification and formatting commands.
- Clarified that the orchestrator should perform linting, tests, and formatting once per phase across all changed files.
- Added a <critical> instruction block to the coding-agent system prompt.
- Prohibited narration of token limits, budgets, effort estimates, and scope-inflation speculation during task handling.
- Normalized tool discovery token parsing with Unicode decomposition, removing combining marks and splitting acronym and camel-case boundaries for better tokenization.
- Expanded token separators to treat any non-letter or non-digit character as a boundary during indexing.
- Added a BM25_DELTA term to the BM25 scoring calculation to adjust relevance scoring for matching terms.
- Updated `irc` tool availability logic to require both `irc` settings and concurrency support.
- Imported `MAIN_AGENT_ID` and suppressed IRC access for the main agent when async mode is disabled, preventing sync-mode peer messaging.
- Pre-registered agents in the global registry before rebuilding the system prompt so peers can discover each other in initial IRC blocks.
- Replaced immediate registry replacement with attachSession to bind the live session and latest sessionFile to the pre-registered entry.
- Ensured pre-registered agents are unregistered during creation failure cleanup when no session was established.
- Replaced project, subagent, and system prompt templates to use bracket-style `[TAG]...[/TAG]` markers instead of `<|START_*|>`/`<|END_*|>` markers.
- Updated system-prompt and subagent reminder tests to assert the new bracket tag format for role, context, and contract blocks.
- Added an Unreleased changelog entry for the subagent batch registry initialization behavior.
- Replaced `===== ... =====` eval cell headers with `*** Begin ` / `*** End ` markers; legacy format remains renderable in HTML exports.
- Replaced hashline patch grammar with `*** Begin Patch` / `*** End Patch` envelope; old inputs without the envelope are still accepted.
- Extracted `sniffEvalLanguage` into a shared `sniff.ts` module reused by the parser and tool.
- Added `docs/ERRATA-GPT5-HARMONY.md` and `scripts/session-stats/harmony_backtest.py` documenting and backtesting the GPT-5 Harmony-header leak defect.
- Deleted `bash-normalize.ts` and its tests; output truncation is handled by the streaming tail buffer and artifact spillover.
- Removed `head`/`tail` schema fields from `bashSchema` and `BashToolInput`.
- Updated system prompt and bash tool prompt to forbid `| head`/`| tail` pipes and other anti-patterns, directing the agent to use dedicated tools instead.
The 50ms retry loop in #scheduleBackgroundExchangeFlush had no guard
against session teardown. If dispose() was called while streaming,
the setTimeout callbacks kept firing and attempted emitExternalEvent
on a disconnected agent.
- Add #isDisposed flag; set it at the top of dispose() before any
async teardown so poll ticks that fire mid-teardown bail out cleanly
- Clear #pendingBackgroundExchanges in dispose() to drop queued
messages that will never be rendered
- Widen the attempt() bail condition to include #isDisposed so the
loop terminates even if new messages arrived between the dispose()
clear and the next tick
new URL(...).pathname returns a POSIX-style /D:/... path on Windows, which
is not a valid filesystem path. import.meta.dir gives the correct native path
on all platforms.
- Added immutable metadata to protocol handlers and had the router copy each handler's setting onto resolved internal resources.
- Updated read and search tools to honor `resource.immutable`, and made search suppress hashline anchors only for immutable source paths while preserving them for mutable files.
- Expanded internal URL tests to cover mutable local resources and mixed immutable/mutable search input hashline behavior.
- Added explicit prompt markers and wrappers across system templates, including `[env]`, `[role]`, `[coop]`, `[closure]`, and `[now]`.
- Removed `renderTemplate` and `sectionSeparator` flows, deleted `task/template.ts`, and switched to per-task `renderSubagentUserPrompt` rendering.
- Updated system prompt assembly to `shortenPath`-normalize `cwd`, append rendered now metadata, and preserve trailing `[now]` blocks.
- Removed legacy template tests and added prompt-composition tests for ordered `[contract]`->`[project]`->`[now]` blocks and context-only system placement.
- Reworked shared prompt utilities by collapsing consecutive blank lines and removing obsolete `OPENING_HBS`/`LIST_ITEM` helper behavior.
- Removed the brace-only structural bigram helper path from the line hash logic.
- Punctuation-only lines now follow the non-significant-character path using index-seeded xxHash hashing for their hash.
- Updated the hashline line-hash comment to describe that non-significant lines use the line-number-seeded seed.
- Extended splitPathAndSel to detect compound selectors that combine a line range with `raw` in either order.
- Updated read selector parsing to support `:lines:raw` and `:raw:lines` selectors and propagate raw-mode handling through internal URL, archive, and notebook paths.
- Added tests covering compound selector syntax and confirming it returns verbatim content without anchors or line-number prefixes.
- Added a collapsible tools header with chips and intent metadata styles in HTML exports.
- Added eval tool support with cell-level parsing and inferred language syntax highlighting.
- Added dedicated renderers for search, recipe, and irc tool calls and separated `_i` intent from tool args.
- Enhanced edit, ast_edit, find, search, and gh renderers with richer headers, fields, and option badges.
- Changed power-assertion state so assertions were prompt-scoped and no longer blocked after aborts.
- Extended file-display resolution to accept an immutable flag and suppress hashline anchors when immutable sources are requested.
- Plumbed immutable propagation through ReadTool and SearchTool so internal URL reads and searches pass that context.
- Added a regression test confirming artifact:// search output no longer includes hashline anchors.
- Added macOS power assertion settings for idle, system, user, and display with schema defaults.
- Added idle, system, and user options to MacOSPowerAssertionOptions in TS typings and Rust, preserving display.
- Changed agent-session power flow to use begin/end/reset in-flight helpers and avoid manual counter updates.
- Updated power assertions to combine multiple kinds per native handle and support safe repeated-stop behavior.
- Updated unreleased changelog notes to document the breaking behavior and canceled-prompt unblock correction.
- Added `listWorkspace` native binding and API types, exporting bounded workspace trees with AGENTS.md candidates.
- Reworked `buildWorkspaceTree` and `buildDirectoryTree` to call `listWorkspace` with 5s timeout defaults.
- Replaced startup AGENTS.md discovery with workspace-tree-only scanning and removed legacy AgentsMdSearch session plumbing.
- Updated `WorkspaceTree` and system prompt context to expose `agentsMdFiles` and aligned tests/changelog expectations.
- Dropped the `modify` edit type and its `< ANCHORTEXT` / `+ ANCHORTEXT` syntax.
- Removed associated parser rules, regex patterns, apply logic, and tests.
- Deleted the "Append WITHIN a line" example from the prompt docs.
- Added a 30s timeout for extension handlers in runner.ts so stalled callbacks now emit warnings and stop.
- Consolidated duplicated extension handler error handling by routing calls through #runHandlerWithTimeout.
- Introduced a flag to detect when an explicit modelRegistry was supplied to runSubprocess.
- Skipped modelRegistry.refresh() when reusing the parent registry and retained refresh when creating a new one.
- Added a debug log to indicate when a parent modelRegistry is reused and refresh is bypassed.
- Refactored SSE response parsing to read the stream with a single in-progress drain loop.
- Resolved the matching request promise when the expected JSON-RPC result or error arrives and continued dispatching remaining SSE messages on the same stream.
- Adjusted error handling to reject on abort/timeout or missing response and clear the timeout when stream parsing completes.
- Updated task call rendering to use `args.tasks?.length ?? 0` when displaying agent counts.
- Prevented runtime warnings in streaming task calls when the `tasks` array was still undefined.
- Updated the hashline prompt to clarify that anchors must use the file state from the most recent read.
- Added guidance warning not to renumber line references when stacking multiple patch operations.
