Deferred the status-line quota refresh off the render path and raced it against a short startup timeout so slow Anthropic usage lookups cannot pin interactive startup. Added regression coverage for non-synchronous refresh startup and timeout backoff.\n\nFixes #3057
- Improved thinking loop detection logic by refining text normalization and treating stalls as retryable errors.
- Instrumented the agent session to recognize thinking loop markers within retryable error conditions.
- Automated the clearing of stale error banners upon successful auto-retry execution.
- Added comprehensive test coverage for chunked thinking loop errors and banner management.
- Moved authentication logic to `perplexity-auth.ts` to share logic between search providers and CLI commands.
- Updated authentication priority to prefer browser cookies over OAuth tokens during search operations.
- Modified the `token` CLI command to display active OAuth tokens when both an OAuth token and an API key are configured.
- Added comprehensive unit tests in `perplexity.test.ts` to verify authentication priority and precedence.
- Replaced usage of `ReturnType<typeof setTimeout>` and `ReturnType<typeof setInterval>` with the explicit `Timer` type across the codebase.
- Updated several type definitions and function signatures to use concrete types instead of inferred return types for improved clarity and maintainability.
The PR fixed the -32601 hang for the defined server->client refresh
requests but missed two real spec methods of the identical class:
workspace/inlineValue/refresh (LSP 3.17) and workspace/foldingRange/refresh.
A server emitting either still received Method not found and could stall.
Add both to the void-ack chain and extend the regression test.
- Implement JSON repair and strict argument validation to sanitize raw payloads and redact sensitive information from agent event logs.
- Add automatic authentication fallback for benchmark model resolution to ensure consistent performance testing across providers.
- Refactor search tool API parameters by replacing `i` with a case-sensitive `case` boolean flag for clarity.
- Update session history formatting to ensure empty objects are consistently serialized as `{}` instead of empty strings.
- 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.
- Replaced regex-based markdown detection with a stateful parser in `detectLiveReflowingMarkdown`.
- Correctly ignore table delimiters and mermaid markers when they appear inside fenced code blocks.
- Added tests to verify that code blocks containing markdown-like syntax do not prevent commit stability.
- Prevent object reference sharing between agent snapshots and stream events by deep-cloning tool-call arguments.
- Stabilize GFM tables and Mermaid diagrams during streaming by delaying transcript block commits until content finalization.
- Implement session resume safety to prevent crashes when working directories are missing.
- Add comprehensive test suites to verify streaming commit stability and immutable snapshot isolation.
- Shortened language in `browser.md`, `eval.md`, and `prompt.md` to improve clarity and reduce token consumption.
- Refined instructional phrasing throughout the tool documentation for better readability.
- Replaced O(n) `Array.shift()` calls with O(1) head-index tracking in `RawSseDebugBuffer`.
- Implemented lazy compaction to reclaim the dead-prefix memory only when the leading window grows sufficiently large.
- Added comprehensive tests to verify ordering, dropped count accuracy, and buffer limits under heavy load.
- Add `onFirstChatDispatch` hook to `CreateAgentSessionOptions` to track the boundary between session creation and the initial model request.
- Update `runSubprocess` and `TaskTool` to measure and log detailed latency metrics across the subagent lifecycle, including semaphore queue wait, setup time, and dispatch latency.
- Added weighted selection logic to bias discovery toward "[NEW]" tips.
- Updated the tip marker regex to allow trailing whitespace.
- Migrated tip selection to use the new biased distribution algorithm.
- Delay the creation of the extension context until a relevant handler is identified.
- Avoid unnecessary performance overhead for events that have no registered handlers, such as frequent streaming updates.
- Added an early return to stop event propagation if no handlers are registered for the event type.
- Updated the `agent_start` logic to return early, ensuring consistent flow control.
- Introduced a "[NEW]" marker in tip text that triggers an animated rainbow-colored tag in the welcome component.
- Implemented `renderNewTag` to calculate cyclic HSL hue offsets based on render timing.
- Updated `renderWelcomeTip` to intelligently wrap the tag at the end of the last line or on a new line to prevent layout overflow.
- Simplified system and personality prompts for improved conciseness and clarity.
- Streamlined tool instruction sets and parameter descriptions across all agent modules.
- Refactored prompt documentation in `hashline` to clarify terminology and task-specific constraints.
- Updated tool metadata in TypeScript service definitions to align with reduced documentation verbosity.
- Removed the customizable `timeout` parameter from the tool schema and implementation.
- Fixed the timeout duration to 5 seconds to simplify tool usage.
- Updated documentation and error messages to advise narrowing search patterns instead of adjusting timeouts.
- Introduced a centralized `discoverAuthStorage` mechanism across packages to unify credential retrieval and configuration resolution.
- Added support for new Gemini and Moonshot model variants while updating context window and effort configuration for existing models.
- Resolved provider-specific 400 errors for OpenRouter and GLM models by refining reasoning effort mapping and retry logic.
- Standardized credential management in both the coding-agent and model catalog by migrating to the unified authentication broker.
- Updated the system schema and prompt options to disable inline tool descriptors by default.
- Modified the build system prompt logic to reflect the new default fallback value.
- Export `directoryExists` in `utils` to safely validate working directories before traversal.
- Update `SessionManager` and startup logic to fallback to the launch directory if a session's recorded working directory no longer exists.
- Add regression tests to ensure sessions now correctly adopt the launch directory instead of crashing on missing paths.
- Add `directoryExists` check to validate session working directories.
- Skip updating the session cwd if the recorded directory no longer exists on disk to prevent runtime errors.
Skip the secondary loadSystemPromptFiles capability walk when the caller already controls block 0 via customPrompt/resolvedCustomPrompt, so project/user SYSTEM.md cannot silently augment a CLI --system-prompt override.
Fixes#3014
handleServerRequest fell through to a JSON-RPC -32601 Method not found for several defined server -> client requests (window/showMessageRequest, window/showDocument, workspace/{semanticTokens,inlayHint,codeLens,codeAction,diagnostic}/refresh). Servers that block on a real reply -- the same failure class as the client/registerCapability hang fixed in #3029 -- could stall waiting for an acknowledgement that never came.
Reply with the spec no-op result instead: null for showMessageRequest / *Refresh, { success: false } for showDocument. Headless omp cannot honour the UI surface, but it still owes a defined response.
Fixes#3044
ModelRegistry registers a built-in llama.cpp discovery as `provider:
"llama.cpp"` (model-registry.ts:1063), so a reverse-proxied or
public-DNS llama.cpp endpoint never trips the loopback heuristic and
was still falling through to no append-only context.
Add "llama.cpp" to LOCAL_INFERENCE_PROVIDERS, refresh the docstring
on `hasLocalLoopbackBaseUrl` (it covers user-defined providers; built-
in local ids are caught by the allowlist), and extend the test to
exercise a public-host llama.cpp baseUrl so the allowlist path is
covered independently of the loopback heuristic.
Refs #3033
Ollama, LM Studio, and llama.cpp / vLLM all do byte-prefix KV cache reuse
on the model server side. The agent loop's non-append-only path rebuilds
the system prompt and tool catalogue on every turn through fresh
allocations (`normalizeTools`, `convertToLlm`, optional memory-backend
`beforeAgentStartPrompt` injection), which dirties enough leading bytes
to invalidate the cache and force a full prompt re-evaluation.
`shouldAutoEnableAppendOnlyContext` previously only recognized DeepSeek
and Xiaomi Token Plan. Extend the auto-detect:
- Allowlist the known local-server provider ids (`ollama`,
`ollama-cloud`, `lm-studio`).
- Detect user-defined local servers by parsing `baseUrl`: loopback,
RFC1918 private IPv4, and `.local` mDNS hostnames.
- Keep the existing `compat.supportsStore` opt-in escape hatch and the
explicit `provider.appendOnlyContext: on`/`off` override paths.
Regression coverage in `append-only-context-mode.test.ts` exercises
each new positive case plus negative samples (172.15/172.32 just outside
RFC1918, public hosts, malformed URLs).
Fixes#3033
After `shutdownMnemopiEmbedClient()` clears `#worker` (session dispose, or
worker crash), mnemopi still holds the cached `LocalEmbeddingModel` wrapper.
The next embed re-spawned a fresh subprocess that had never received
`init`, and the bare `embed` request tripped the "embed before init" guard,
breaking local embeddings for the rest of the process.
- Carry `model` + `cacheDir` in every `embed` IPC; bind both into the
`MnemopiSubprocessEmbeddingModel` closure when the wrapper is created.
- Worker calls `ensureLoaded(model, cacheDir)` in `handleEmbed` (idempotent
for the same key, so steady-state embeds pay nothing). Drops the
"embed before init" guard — `embed` self-initializes.
- Promotes the internal `WorkerHandle` interface to `MnemopiEmbedWorkerHandle`
so the test seam can construct a fake worker.
- New regression test drives a fake worker, terminates + re-embeds the SAME
cached wrapper, and asserts every embed message still carries the bound
`(model, cacheDir)`.
Per review on #3034.
Stopped image tool registration from resolving provider credentials during session startup. Added coverage that registration stays lazy while execution still resolves credentials.
Fixes#3036
Moved mnemopi's local embedding provider out of the main agent process by
spawning a dedicated `Bun.spawn` child for fastembed + onnxruntime-node. The
agent CLI gains a hidden `__omp_worker_mnemopi_embed` dispatch; `loadMnemopi`
/ `loadMnemopiCore` install the subprocess-backed initializer through the
newly-exposed `setLocalModelInitializer` seam so every `embed()` call
round-trips through IPC instead of loading the NAPI module. The parent
SIGKILLs the child on dispose so the destructor that segfaults Bun on
Windows shutdown (NAPI finalizer at exit on npm installs, `process.dlopen`
constructor at session start on standalone binaries) never runs in any
address space the agent owns. Mirrors the tiny-model fix from #1607.
Adds `smokeTestMnemopiEmbedWorker` to `omp --smoke-test`, a new
`test/issue-3031-repro.test.ts` that pins the spawn/dispatch/signal-exit
contract and forbids re-importing `fastembed-runtime` from the agent surface,
and changelog entries.
