- 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.
- 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.
- Added `sessionId` and `cwd` tracking to JS evaluator session instances.
- Updated `acquireSession` in the JS context manager to update existing session identity and directory metadata on reuse.
- Forwarded the current working directory from `executePerCall` and `executeOnSession` callers to the underlying Python kernel tasks.
- 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.
- Forwarded `parentAgentId` through task and eval launch paths when spawning subagents.
- Mapped `parentAgentId` to `parentId` in `createAgentSession`.
- Passed each caller's session `getAgentId` (or `MAIN_AGENT_ID`) as the parent for spawned agents.
- Added a return_handle (Python) / returnHandle (JS) option to the eval agent() helper that returns a DAG node dict { text, output, handle, id, agent } instead of bare text, where handle is the spawned agent's recoverable agent:// URI.
- Enabled downstream pipeline/parallel stages to reference a large transcript by handle/output instead of re-inlining it; the default path stays backward compatible (bare text, or the parsed object under schema).
- Documented return_handle and the acyclic DAG-wiring pattern in the eval tool description and added a VM-level prelude regression test for the node shape and the no-details fallback.
- Added `WorkerInbox` and `installWorkerInbox(port)` to queue worker messages before bind.
- Added `consumeWorkerInbox()` to replay buffered messages and clear one active inbox.
- Added buffered inbox consumption in JS and tab worker transports before direct message handlers.
- Normalized worker selector arguments to the `__omp_worker_*` naming across workers and tests.
- Replaced Bun.sleep and wall-clock timing with fake timers (vi.useFakeTimers), release gates, and deterministic polling across 15+ test files to eliminate flakiness and improve speed.
- Consolidated per-test fixture setup into beforeAll/afterAll lifecycle hooks across 20+ test files, reducing redundant initialization and improving test performance by reusing shared immutable fixtures.
- Stubbed network calls in ModelRegistry and test discovery to prevent unintended outbound requests during test execution.
- Replaced subprocess-based test coordination (file markers, Bun.sleep polling) with in-memory fakes (FakeWebSocket, FakeLspServer, VirtualClock) for deterministic, fast test execution.
- Updated worker core so it emitted `ready` only after receiving an `init` message instead of on construction.
- Changed worker startup to send `init` before waiting for readiness, enabling startup errors to fail fast and trigger fallback.
- Expanded JS worker tests with startup-error simulation and verified execution falls back to the inline worker when spawning fails.
- Initialized JS workers through a new helper that attaches message and error listeners before initialization handshake and enforces the existing ready timeout.
- Handled startup failures by rejecting on init or error events, cleaning up listeners and replacing dead workers with a retry path.
- Retried session creation with an inline worker after non-inline init failure so requests no longer stall on worker startup timeouts.
- Added runtime hook resolvers so each `JsRuntime` instance can expose hooks for its active run.
- Patched `process.stdout` and `process.stderr` writes once per stream to route output chunks through active run text hooks and preserve existing worker logging when no run is active.
- Added chunk-to-string conversion for write payloads and encoding-aware forwarding while keeping callback semantics intact.
- Updated CI dependency install flow to share bun cache orchestration across jobs.
- Added RustFS-backed bun cache restore/save script keyed by bun.lock hash.
- 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 session-domain modules and exports for session-entries, context, listing, loader, and migrations.
- Changed persistence to async append writes plus writeTextAtomic, removing sync line APIs.
- Added compaction-aware session context rebuild with dangling tool-call cleanup.
- Added resumable session resolution with status inference, id/stem/suffix matching, and backup recovery.
- 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.
The task tool now takes a single { agent, assignment, description, ... } and always runs the subagent in the background — the batch tasks[] array and shared context parameter are gone. Fan-out is parallel task calls; shared background flows through a '/Users/can/.omp/agent/sessions/-Projects-.tree-pi-commit/2026-06-10T15-36-32-782Z_019eb22d-970e-7000-8964-72c98becf3e8/local' file referenced in each assignment.\n\nIntroduces a persistent subagent lifecycle: finished subagents stay live as idle, the lifecycle manager parks them to disk after task.agentIdleTtlMs (default 7 minutes; 0 keeps them live until exit), and they revive automatically when prompted from the Agent Hub, messaged on IRC, or resumed via task. New task(resume: "<id>") revives an idle or parked subagent and runs a follow-up assignment in its existing session.\n\nAdds soft request budgets (explore/quick_task 40, others 90, configurable via task.softRequestBudget, 0 disables): crossing the budget injects a one-time wrap-up steer into the child; crossing 1.5× aborts the run gracefully. Cancelled/aborted subagent salvage replaces the old (no output) with the child's last activity snippet plus request/token stats; SingleResult tracks a per-child requests counter (assistant message_end events) used to sort agent lists in runtime-ascending order in both the live progress view (finished agents above pending/running) and the finalized result view, so rows no longer reshuffle on finalize. Adds a task gallery fixture variant for the resume path (renderer key separated from fixture key).\n\nAll task tests are reshaped around the single-call contract; tests for the discarded shared-context flow are removed, and new task-guards/task-resume/task-schema tests pin the new contract surface.
Shared background now flows through a '/Users/can/.omp/agent/sessions/-Projects-.tree-pi-commit/2026-06-10T15-36-32-782Z_019eb22d-970e-7000-8964-72c98becf3e8/local' file referenced in each prompt instead of a context string forwarded into the subagent's system prompt. The JS and Python preludes drop the context kwarg from agent(), the subagent system prompt drops the {{#if context}} block and the conversation-context file pointer, and runEvalAgent no longer writes a per-call conversation context file. AgentSession sheds the now-unused formatCompactContext() helper that supplied the file's body, and ToolSession.getCompactContext is removed alongside it.
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.
- Added CredentialRankingStrategy scope hooks so providers can rank and block only the limits relevant to the requested model.
- Scoped Antigravity usage reports by model family: Gemini/Gemma use Google counters, Claude uses Anthropic counters, and GPT/OpenAI models use OpenAI counters.
- Added scoped backoff keys so a Gemini quota block no longer suppresses healthy Claude/OpenAI Antigravity sessions on the same OAuth credential.
- Threaded modelId through coding-agent API-key resolvers and usage-limit rotation paths.
- Added regression coverage proving a Google/Gemini exhaustion block still allows Claude selection on the same credential.
Fixes#2198
- Replaced minLevel/maxLevel range with explicit efforts array plus baked effortMap/supportsDisplay wire facts.
- Removed runtime enrichment layer and modelOmitsReasoningEffort; providers now read baked fields.
- Fixed dotted Opus 4.7/4.8 ids missing adaptive display via classifier-based predicates (#1373).
- Bumped model cache schema to v4 to invalidate pre-efforts rows.
Move bundled models, model cache/manager, thinking metadata, effort helpers,
provider descriptors/discovery, wire constants, and model identity utilities
into the new @oh-my-pi/pi-catalog package.
Update pi-ai to keep provider runtime/auth concerns, move catalog provider
metadata into CATALOG_PROVIDERS, and migrate coding-agent, agent, stats, docs,
and tests to import catalog values from pi-catalog.
Split coding-agent model registry helpers into discovery, roles, and models
config modules while preserving registry orchestration.
BREAKING CHANGE: @oh-my-pi/pi-ai no longer exports catalog subpaths such as
/models, /model-cache, /model-manager, /model-thinking, /effort,
/provider-models*, discovery helpers, and provider wire constants; use the
matching @oh-my-pi/pi-catalog subpaths instead.
- 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.
- Rerouted sync, tab, js-eval, and tiny workers to re-enter CLI modes via `__omp_*` selectors.
- Adjusted `cli.ts` startup to dispatch worker entrypoints before parsing and exit 1 on uncaught errors.
- Bundled CLI as `dist/cli.js` in prepack, switching `omp` binary and published files.
- Removed explicit Bun `--compile` worker entrypoints from build/release scripts in favor of host-entry dispatch.
- Added `declareWorkerHostEntry()` and `workerHostEntry()` environment helpers and `PI_COMPILED` binary detection.
- Introduced memoized dynamic import loaders for Babel parser, mnemopi modules, puppeteer, and HTML-related packages.
- Refactored eval import-rewrite helpers and runtime call sites to use asynchronous wrapping and parsing flows.
- Shifted fetch and web-scraper linkedom usage to on-demand imports so heavy modules load only when needed.
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.
- Changed runEvalAgent to always pass enableLsp: false when launching bridge subagents.
- Added a regression test asserting runSubprocess received enableLsp as false even when LSP is enabled by default.
- Renamed eval oneshot helper from llm() to completion() across JS/Python APIs.
- Remapped eval bridge internals to completion semantics (__completion__, runEvalCompletion, completion status op).
- Updated docs, prompts, and timeout guidance to describe completion() usage and behavior.
- Adjusted completion defaults for active-session model preference, fallback parsing, and slow-tier effort handling.
- Added strict option parsing for JavaScript helpers so read/sort/uniq/counter/tree/llm/agent now reject positional options and non-object option values.
- Introduced `optionsArg` and `isPlainObject` to enforce a single trailing options object and throw clear TypeError messages on invalid calls.
- Updated the eval tool prompt to document that JavaScript helpers require one trailing options object and no extra positional arguments.
- 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.
- Ensured eval LLM calls always include a non-empty system prompt to avoid 400s.
- Aligned eval tool docs with session spawn policy by omitting agent() when spawns are disallowed.
- Added regression coverage for default system prompts and spawn-aware agent() description behavior.
- Updated `packages/coding-agent/src/eval/py/prelude.py` to accept positional `offset` and `limit` in `read()`.
- Added regression coverage in `packages/coding-agent/src/eval/py/__tests__/prelude.test.ts` for positional read signatures.
- Added first-party-first provider priority defaults for model ranking.
- Consolidated model resolution to use getModelMatchPreferences from session settings.
- Prioritized providerPriorityRank ahead of usage rank when picking preferred models.
- Added second-pass fallback to default-model or API-key-valid matching order.
