- Updated hashline section parsing to accept headers with any leading `@` characters, normalizing them to the path before validation.
- Updated the hashline grammar and fallback errors to use canonical `@@ PATH` section headers.
- Added coverage for mixed `@@` and `@@@` headers across multiple file sections in hashline parsing tests.
- Added `:conflicts` and `read conflict://<N>`/`read conflict://<N>/<scope>` support and rejected wildcard conflict reads.
- Added bulk conflict resolution via `write({ path: "conflict://*", ... })` across files with per-file grouping.
- Expanded conflict detection to scan files up to 10MB, track insertion-ordered history, and report full `X of Y` summaries.
- Reworked `spliceConflict` to match marker blocks by content, fixing shifted or stale block splicing.
- Added coverage for wildcard parsing, scoped reads, prepended-line splices, relocation, and warning assertions in detect/integration tests.
- Introduced canonical `*** Cell` headers with `t:` and `rst` attributes in eval prompts, schema, and docs.
- Updated parser and grammar to parse `*** Cell` blocks, stop on `*** End`/next header/EOF, and handle invalid `rst` with errors.
- Added quote-aware attribute tokenizers and split HTML eval parsing into `Cell` and legacy `Begin` handlers with `py` defaults.
- Expanded parsing behavior and tests for `rst` booleans, title aliases, abort boundaries, and stray-line skips between cells.
- 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.
- 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.
- 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.
- 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.
- 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.
The 30 second default for 'ask.timeout' silently auto-selects the
recommended option mid-deliberation, which surprises users who are
weighing options the agent flagged as having materially different
tradeoffs. The setting was meant to be opt-in: 0 already means
'wait indefinitely' and plan mode already forces the timer off.
Flip the default to 0 so a fresh install matches the documented
'wait until the user replies' behavior, and update the AskTool
prompt so the model expects unlimited reply time by default. Users
who liked the auto-select can still set a positive timeout from
the Interaction settings tab.
Add a regression test asserting the dialog timeout is not passed
to the underlying selector when 'ask.timeout' is unset.
- 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.
- 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.
- 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.
- 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.
- Updated the hashline grammar to require a full `LID .. LID` range for block operations.
- Enhanced `parseRange` to reject single-anchor syntax and malformed ranges, and to require duplicated anchors for one-line edits.
- Reworked hashline prompt examples/tests accordingly and added coverage for single-anchor delete/replace forms.
- Clarified the hashline guidance to select a self-contained syntactic unit before narrowing the edit operation.
- Added a multiline destructuring/call example showing the full construct replacement pattern and safer alternatives.
- Updated anti-pattern instructions to reject partial-boundary replacement payloads and continuation-fragment edits.
When a patch introduces a new type that crosses a function/module
boundary (event, message, RPC frame, enum variant, etc.), the reviewer
must locate the dispatch point on the consuming side and confirm the
new type is handled. This class of bug is invisible from the diff alone
because the silent drop lives in untouched routing code.
Motivated by a missed P2 in PR #987: a new open_url extension_ui_request
was emitted by login() but RpcClient#handleLine had no case for it and
silently dropped every frame, leaving callers with no auth URL and the
command hanging until timeout.
- Updated `hashline.md` to document brace-boundary edit patterns for block replacement, signature-only edits, and safe interior insertions.
- Added common-failure guidance on range boundaries, duplication checks, truncated anchors, and preferring narrower ops over wide replacements.
- Adjusted the anti-pattern example to match the corrected replacement range behavior.
- Added a Python `analyze.py` CLI with `tools`, `edits`, and `followups` session-stats subcommands.
- Added `sync.py` ingestion with `~/.omp/stats.db`, migration SQL, and incremental JSONL resume logic.
- Replaced `stats:run` in `package.json` with `stats:sync` and new `stats:edits`, `stats:tools`, and `stats:followups` scripts.
- Removed the Rust session-stats crate files (`Cargo.toml`, `main.rs`, `common.rs`, `cmd_*.rs`) and their old command logic.
- Removed `.gitignore` ignores for `scripts/session-stats/Cargo.lock` and `scripts/session-stats/edit-analysis.csv`.
- Updated eval tool guidance to show Python `asyncio.run(...)` usage.
- Added an instruction in the Python eval prompt explaining that notebook cells run in an IPython kernel with a live event loop.
- Documented that users should use top-level `await` directly and avoid `asyncio.run(...)` due to the running event loop.
- Kept the existing failure-handling guidance unchanged while clarifying async execution behavior for Python cells.
- Updated system prompts to require every active turn to end with a tool call and clarified that reminders should default to resuming work unless the task was complete or genuinely blocked.
- Reworked the yield-reminder text to disallow fake blocker reasons and to permit continued tool-calling instead of forced immediate yields.
- In `runSubprocess`, applied `toolChoice` only on the final yield retry by adding an `isFinalRetry` check before sending the reminder.
- Updated the read tool docs to define URL selectors as `:50`, `:50-100`, and `:50+150` and to document the `https://host/:port` form for URLs with explicit ports.
- Changed URL selector parsing to use the file-style numeric range format, treated `raw` as a separate token, and updated the invalid zero-line message to direct users to `:1`.
- Refined embedded URL selector extraction to validate the base URL first and then match selectors against the new numeric range regex.
- Removed the read CLI argument and tool schema field so read requests no longer accept custom timeouts.
- Updated URL read handling to stop forwarding timeout values and execute URL reads without a timeout parameter.
- Standardized URL read fetching to a fixed 30-second timeout and dropped timeout metadata from URL call rendering.
- Removed [blocked]-focused instructions from failure handling and pre-yield checks in the system prompt.
- Eliminated the separate completion-honesty block and folded stronger end-to-end-completion language into the contract sections.
- Reworded output and critical-response guidance to focus on continuous progress and completion-only yielding.
- Added a new `orchestrate.md` prompt under `src/prompts/commands` defining an orchestrator workflow, verification gates, and anti-patterns.
- Imported and rendered the prompt in `src/task/commands.ts` as `orchestrateMd`.
- Appended the new prompt to `EMBEDDED_COMMANDS` so it is registered with existing embedded command templates.
- Updated the hashline prompt to require replacement ranges to cover entire statements or expressions, preventing broken syntax when applying changes.
- This clarified how replacement anchors should be chosen for function calls, literals, blocks, and control-flow branches.
- Added a new completion-honesty section to the coding-agent system prompt with stricter delivery constraints.
- The prompt now requires all acceptance criteria to be met before completion, prohibits scope reduction without approval, and forbids delivering stubs, placeholders, or fake implementations as finished work.
- Verification language was tightened so completion claims must reflect actual verification and not be inflated by partial checks.
- Added `.ipynb` detection and editable-cell conversion utilities, including merge/serialize helpers in `edit/notebook`.
- Rerouted hashline, patch, and replace edit flows, plus read/write paths, through notebook-aware helpers before persistence.
- Removed the dedicated `notebook` tool, its schema flags, renderer, and built-in registration/settings checks.
- Updated notebook read behavior, docs, and tests so `.ipynb` reads return editable `# %%` cells and edits reserialize to JSON.
- Removed persona preambles ("You are an expert...") in favor of direct imperatives.
- Stripped redundant MUST/SHOULD modals where plain prose suffices.
- Condensed multi-sentence instructions into tighter single-line equivalents.
- Updated the `init` operation to require a `list: [{phase, items: string[]}]` payload and to replace any existing list.
- Updated the `append` operation description to state tasks are appended to a given `phase` and that the phase is lazily created.
The internal class is now SearchToolsTool but the wire name stays
"search_tool_bm25" so persisted MCP selections in user session files
continue to resolve correctly.
The BM25 corpus is now drawn from the generic DiscoverableTool list
(built-ins, MCP, extension, custom) rather than only MCP tools.
createIf fires when either tools.discoveryMode !== "off" or the
legacy mcp.discoveryMode is true.
AgentSession gains generic discovery methods (isToolDiscoveryEnabled,
getDiscoverableTools, getDiscoverableToolSearchIndex,
getSelectedDiscoveredToolNames, activateDiscoveredTools). The existing
MCP-named methods are kept as thin shims that filter by
source === "mcp" so existing callers continue to work.
Updated the tool's prompt copy to advertise discovery across all
sources rather than MCP only. Tests extended for the new shape.
- Added `pr_create` to the GitHub tool schema and execution dispatch.
- Implemented `executePrCreate()` with title/fill validation, arg assembly, and temp-file body handling.
- Added optional PR result enrichment by parsing created PR URLs and formatting `gh pr view` summary fields.
- Updated `github.md` docs, changelog notes, and tests for `pr_create` mappings and validation.
- 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.
- Added `WorkspaceTree` and `buildWorkspaceTree` APIs for working-directory tree rendering with limits.
- Extended `buildSystemPrompt` and `createAgentSession` to resolve and pass workspace tree context for system prompts.
- Updated the system prompt template to include a `<workspace-tree>` section with truncation notices before append output.
- Added workspace-tree and system-prompt tests covering sorting, truncation, exclusions, and prompt ordering.
