- Renamed the `find` and `search` tools to `glob` and `grep` respectively across the codebase to improve command clarity.
- Implemented full-stack support for the renamed tools, including CLI arguments, system prompts, SDK exports, and tool registration.
- Added automated migration logic in `settings` to transform legacy `find` and `search` configuration keys to their new equivalents.
- Updated the `collab-web` renderer registry to ensure backwards compatibility with legacy tool outputs.
- Added tree-sitter markdown support to resolve headings into full sections in `pi-ast`.
- Enabled block operations (`SWAP.BLK`, `DEL.BLK`, `INS.BLK.POST`) on markdown headings so they encompass the entire section, including nested deeper headings.
- Updated system prompt to guide agents in using structured markdown heading edits for plans.
- Fixed `plan-mode-guard` to correctly resolve local protocol options for subagents.
- Automatically rebind edits to the correct file when an authored path does not exist but the filename and snapshot tag uniquely match a file read earlier in the session.
- Prevent path recovery for paths that would escalate write privileges, ensuring compatibility with read-only internal URL targets.
- Surface warning messages to the model and user upon successful path recovery to encourage correct future path usage.
Migrate 203 test files (356 call sites) from fs.rm/fs.rmSync to
removeWithRetries/removeSyncWithRetries to reduce EBUSY test failures
on Windows. removeWithRetries is now exported from @oh-my-pi/pi-utils.
The migration uses a regex-based approach that:
- Replaces fs.rm(path, { recursive, force }) → removeWithRetries(path)
- Replaces fs.rmSync(path, { recursive, force }) → removeSyncWithRetries(path)
- Replaces fs.rm(path) → removeWithRetries(path) (no options)
- Skips fs.rm/fs.rmSync inside template literals (bun --eval scripts)
- Adds imports to existing @oh-my-pi/pi-utils import or creates new one
- Removes unused fs imports where fs.rm was the only fs usage (4 files)
- Removed deprecated eval prelude helpers `append`, `tree`, `diff`, `sort`, `uniq`, and `counter` from all supported runtimes.
- Cleaned up runtime implementations, protocol definitions, and UI rendering logic associated with the removed helpers.
- Updated project documentation, prompts, and test suites to reflect the reduced helper API surface.
- Recorded functional changes in the package changelog.
- Implemented persistent execution backends for Ruby and Julia using dedicated kernel processes and NDJSON-based IPC.
- Integrated language-specific prelude environments, runtime path resolution, and security-focused environment variable filtering.
- Exposed configuration options, tool schema updates, and lifecycle management for seamless agent interaction with both languages.
- Added comprehensive integration tests and updated prompt documentation to support the new evaluation capabilities.
Batch migration of 13 fs.rmSync calls to removeSyncWithRetries across:
- core/apply-patch.test.ts (4 calls)
- bash-executor.test.ts (4 calls)
- tools.test.ts (2 calls)
- compaction-hooks.test.ts (1 call)
- compaction-thinking-model.test.ts (2 calls)
Also exports removeSyncWithRetries from @oh-my-pi/pi-utils as a
standalone function for tests that manage their own temp dirs.
All tests pass: 139 pass, 0 fail across the 5 migrated files.
Export removeSyncWithRetries from @oh-my-pi/pi-utils as a standalone
function, then migrate the highest-impact fs.rmSync call sites:
- test/helpers/temp-home-cleanup.ts: 2 fs.rmSync → removeSyncWithRetries
(affects all tests using the cleanupTempHome helper)
- test/core/apply-patch-regression.test.ts: 16 fs.rmSync → removeSyncWithRetries
(the most fs.rmSync calls of any test file)
removeSyncWithRetries retries on EBUSY/EPERM/ENOTEMPTY (40x25ms on
Windows), matching TempDir.removeSync's retry logic. On Linux/macOS
(CI) the retries are a no-op — fs.rmSync succeeds immediately.
- Renamed the global `INTENT_FIELD` constant from `_i` to `i`.
- Updated documentation strings, type annotations, and test expectations across packages to reflect the new field name.
- Ensured consistent usage of the constant in tool schema construction and intent serialization.
- 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.
- Updated all references across `agent`, `ai`, `coding-agent`, `collab-web`, and `snapcompact` packages to import the constant from the new location.
- Added `@oh-my-pi/pi-wire` as a dependency to all affected packages.
- 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 Matplotlib figure PNG rendering and display tracking in Python runner to emit PNG output immediately when figures are displayed via display(fig).
- Extended session persistence to externalize oversized image payloads in both content and details.images, enabling tool result images to survive session reload.
- Enhanced session loader to resolve image data payloads and blob references across content and details.images during session reconstruction.
- Added image cache invalidation in TUI image component when image protocol, cell dimensions, or Kitty Unicode placeholder mode changes.
- Added comprehensive test coverage for Matplotlib display, image persistence across reload, and TUI image rendering with protocol and dimension changes.
- Made `JsRuntime` track the realm globals it installs (`#globalOwner`, `#ownedGlobalKeys`, `PRELUDE_GLOBAL_KEYS`) and reclaim them in `dispose()`, re-binding ownership through `#activateGlobals()` on cwd/run-scope/run; disposing an older inline/direct runtime no longer deletes a newer runtime's helper globals, and overlapping same-realm runs are serialized via `enterGlobalRun`.
- Added `WorkerCore.dispose()` (rejects pending tool calls with `ToolError` and disposes the runtime) and invoked it from `spawnInlineWorker` teardown in `context-manager.ts`.
- Updated the `js-static-import-rewrite` test to snapshot and restore any pre-existing `__omp_import__` global instead of unconditionally deleting it.
- Added `runtime-global-dispose.test.ts` covering newer-runtime global survival, older-runtime reactivation, and cross-runtime mutation rejection.
- Clarified the `runWorkerEntrypoint` comment in `cli.ts` about `parentPort` sync-prefix buffering for tab/eval workers.
Register tree-sitter-elisp in the shared AST language registry so
.el files infer the emacs-lisp grammar across blockRangeAt,
summarizeCode, astGrep/astEdit, and native aliases.
This fixes edit-tool block operations on top-level Emacs Lisp forms
instead of returning unsupported-language block errors.
- Add canonical emacs-lisp aliases and .el extension inference.
- Teach summaries to fold Lisp forms without grouping arbitrary lists.
- Map .el rendering and highlighting aliases through coding-agent/native.
- Cover defun, ERT, use-package, with-eval-after-load, pcase,
summary, astMatch, astEdit, and edit-tool insertion paths.
- Document the language and update package changelogs.
- Renamed line and block patch op verbs to XCHG, DEL, and INS in parsing and formatting.
- Updated grammar and tokenizer to support XCHG.BLK, DEL.BLK, and INS.PRE/POST/HEAD/TAIL forms.
- Updated diagnostics, docs, prompts, tests, and changelog to use XCHG/DEL/INS-based operators.
- Expanded session-stats parsing to normalize legacy op aliases to compact IDs.
- Added a lifecycle test case verifying executePython retries execution with a fresh kernel when the prior session kernel dies during run.
- Removed the now-redundant python-executor-session.test.ts file that defined session lifecycle tests.
- Updated JS eval helper option parsing to accept positional optional args or a trailing plain-object options argument, while rejecting mixed or invalid forms.
- Updated `read` to route non-`local://` URI paths through the `read` tool with line selectors so offset/limit slicing works for artifact-style resources.
- Expanded JS executor tests for positional reads, nullable slot skipping, and delegated URI read slicing.
- Added a shared `formatAnchoredContext` helper and switched mismatch formatting to use it.
- Extended unresolved block-edit errors to append nearby numbered context with `*`-marked anchor lines.
- Updated unit and integration tests and docs to reflect the new unresolved-block preview behavior.
Resolve the explicit interpreter from the session's Settings instance
(ToolSession.settings / AgentSession.settings) instead of re-reading the
process-global Settings.init() singleton, so project-scoped and cloned
session settings take effect. The availability cache is now keyed by
cwd + interpreter, and PythonKernel.start/executePython accept the
resolved interpreter as an option. Also expand home-relative paths
(~/...) before resolving against cwd, and document the contract of
resolveExplicitPythonRuntime.
Addresses review feedback on #2204.
Two pathologies surfaced in the same captured failure (#2081): a subagent
spent 16 minutes hammering 205 `edit` calls (182 byte-identical no-ops)
against a file that already matched its payload, while a sibling bash
invocation persisted 7.6MB of PowerShell rich-object metadata to
`~/.omp/agent/artifacts/<id>.bash.log` from what was intended as a small
tail. Both are addressed independently here:
- Hashline executor now consults a per-ToolSession `noopLoopGuard` that
hashes the raw patch input and tracks consecutive no-ops per canonical
path. After NOOP_HARD_LIMIT (3) repeats of the same payload the soft
"byte-identical" hint escalates to a thrown ToolError, which the agent
loop surfaces as a tool failure rather than success-with-text — far
more effective at breaking the loop than the soft hint alone. A
non-noop commit (or any variant payload) resets the counter; state is
isolated per ToolSession so subagents cannot inherit each other's
history.
- OutputSink artifact-on-disk writes are now bounded by
`artifactMaxBytes` (default 4 MiB = 3 MiB head + 1 MiB rolling tail).
Once the head budget is exhausted, subsequent chunks divert into a
fixed-size tail ring; `dump()` replays the ring behind a single
`[ARTIFACT TRUNCATED: kept first … + last … of …; … elided from the
middle]` notice before closing the sink. Setting `artifactMaxBytes: 0`
restores the historical unbounded behavior. Sized comfortably above
anything a model would reasonably scroll through via the artifact URL
scheme while preventing the captured 7.6MB spray from sitting on disk.
The terminal-typing lag the reporter observed has multiple compounding
causes (transcript-render freezing is disabled on win32; the bash result
renderer lacks the per-render cache that the eval renderer already has).
Those land in a follow-up — the loop guard + artifact cap address the
root pathologies that turned the session into a multi-MB transcript in
the first place.
Fixes#2081
- Added lazy async module loaders for @babel/parser, linkedom, puppeteer/browsers, @mozilla/readability, @xterm/headless, and mnemopi to avoid loading them during cold startup.
- Added an interactive startup splash before session construction and skipped it for resume/fork/continue, quiet mode, timing mode, or non-TTY runs.
- Updated JS import-rewrite and memory tests to match async parser loading and preloaded mnemopi modules for sync state helpers.
single OutputSink owner per cell artifact; JS parallel() honors its documented barrier (allSettled) instead of orphaning in-flight thunks; Python subprocesses no longer inherit the NDJSON frame pipe (stdout captured and forwarded); JS timeouts annotate the VM reset; console bridge implements dir/time/group/assert/trace; python availability probe cached; runner frames coalesce per write.
- Rewrote dynamic `import(...)` rewriting to emit a guarded callee that prefers `__omp_import__` and falls back to native `import` when the helper is unavailable.
- Added a shared shim constant and updated import-rewrite tests to verify routed dynamic imports work both with the injected helper and after serializing into a realm without it.
- 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.
- Substituted injected on-disk roots for `local://` in read/write/append (Python and JS).
- Pinned `local://` to the session's own root so eval writes land where reads resolve.
- Rejected path traversal and unknown `scheme://` paths instead of creating junk `local:` dirs.
- Added unit and integration tests covering resolution, guards, and plain-path passthrough.
- Removed the mid-skip placeholder line that was output when skipping lines in the middle of a diff, relying instead on the line number jump to convey the gap. Removed the corresponding placeholder-filtering logic from the hashline diff preview that was handling these placeholders.
- Modified buildCompactDiffPreview to omit removed lines from output while preserving removal counts for offset tracking.
- Added logic to collapse long contiguous added runs with +<lineNum>... elision marker, keeping configurable edge lines on each side via new maxAddedRunContext option.
- Removed context-gap placeholder rows (... or ...) from model-facing preview, relying on line-number jumps to convey elision.
- Reorganized test suite by moving core contract tests to dedicated core-contracts.test.ts file and diff-preview tests to diff-preview.test.ts for better separation of concerns.
- Added a BlockResolution type and `onResolved` callback so `resolveBlockEdits` reports each anchor's resolved span for `replace block`/`delete block` edits.
- Updated patch application to return those spans on hash-match applies and omit them during drift-recovery paths where line numbers no longer align.
- Propagated the surfaced spans through the edit tool output and added/updated tests covering replace/delete block echo and drift behavior.
- Coalesced concurrent JS and Python reset requests by awaiting in-flight promises instead of throwing.
- Aligned non-reset execution calls to wait for in-progress resets before running on a recreated session.
- Replace recursive stripLeadingHashlinePrefixes with single-pass
stripOneLeadingHashlinePrefix in #handleRaw to prevent over-stripping
content whose own text starts with digits:colon (e.g. YAML ports,
timestamps: 2:42:hello → 42:hello, not hello)
- Export stripOneLeadingHashlinePrefix from prefixes.ts
- Move hashline CHANGELOG entry to [Unreleased] section
- Add regression tests for nested N: prefix and +N: asymmetry
- Replaced `¶path#hash` prefix with `[path#hash]` delimiters across parser, tokenizer, and grammar.
- Updated prompts, docs, and recovery paths to the new bracketed form.
Worker-ready wait reused Bun's 5s default per-test timeout as its floor, so a slow cold-start under --isolate + high CI concurrency was aborted at 5s. The catch then terminate()s a still-initializing Bun worker -- the documented SIGILL/SIGTRAP crash trigger -- crashing the whole test file and intermittently failing unrelated PRs.
Introduce WORKER_INIT_TIMEOUT_MS=15s as a fixed infrastructure floor (independent of, still dominated by, a larger per-cell timeout) and set a 20s file-local setDefaultTimeout in js-executor/js-workflow-helpers tests so cold starts complete instead of being torn down.
- Aligned handoff, reminder, and system-prompt expectations with shortened copy.
- Added HTTP transport test for required initialize failures.
- Guarded SSE startup timeout against stale connection races.
- Updated the grammar to parse replace hunks with zero body lines.
- Changed empty replace execution to emit delete edits across the target range.
- Updated tests to verify empty replace syntax deletes lines while empty inserts still throw errors.
- Added +Nk/+Nm turn-budget parsing with whitespace-boundary matching, multipliers, and hard `!` indicator.
- Added per-turn budget lifecycle plus APIs (`getTurnBudget`, `recordEvalSubagentUsage`) and hard-cap checks in eval runs.
- Added hard budget observability in eval preludes and docs by exposing `budget.hard` and documenting ceiling modes.
- Fixed streaming preview stutter with max-row tracking and padding, with tests for preview height and budget parsing.
