On a probe that exits 0 with valid output but leaves a descendant holding stdout open, the bounded drain previously discarded the captured bytes and cached { gpu: null }. Use the already-captured stdout when the probe itself succeeded; only treat a non-zero/timeout exit as a failure.
Even on exit 0 the GPU probe can leave a descendant holding stdout open. Race the EOF wait against a 250ms grace window so the success path cancels the reader instead of blocking until the descendant exits, and unref the prep deadline timer so a one-shot CLI is not held alive by it once all prep work returns.
Stopped the GPU probe from awaiting stdout EOF after the probe process exits non-zero, which can hang when a wrapper leaves descendants holding stdout open. The regression now covers a killed wrapper with an inherited stdout holder and verifies the scenario process exits before the deadline.
Bun.spawn defaults killSignal to SIGTERM, which a wedged lspci/wmic (or its PATH wrapper) can ignore, leaving the probe alive past the prep deadline and blocking the null-cache write. Force SIGKILL so proc.exited always resolves at the deadline and the next startup hits the cache.
Replaced the Bun Shell call with Bun.spawn + timeout, so a hanging lspci/wmic now receives SIGTERM at the prep deadline instead of keeping the Bun process alive after withDeadline returned. Tightened the regression test to also assert the spawned scenario process exits within the deadline.
Cached empty GPU probe results and routed GPU detection through the system prompt prep deadline so slow WMI/lspci probes cannot block startup indefinitely.\n\nFixes #3835
- Added `includeWorkspaceTree` configuration setting to optionally render the workspace directory tree.
- Configured the system prompt template and SDK to respect this toggle, allowing users to disable the tree to prevent prompt cache invalidation.
- 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.
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
- Renamed `repeatToolDescriptions` to `inlineToolDescriptors` throughout configuration, SDK, and internal session management.
- Set the default value to `true` and updated descriptions to clarify the descriptor inlining behavior.
- Fixed the `/dump` command to prevent duplicate tool inventory output when inlining is enabled.
Added GitHub Copilot instruction-file discovery to the github rule provider path, mapping applyTo frontmatter into always-apply or glob-scoped rules and avoiding duplicate always-apply prompt content when context imports the same file.\n\nFixes #2731
- Renamed ToolCallSyntax type to Dialect and Grammar interface to DialectDefinition across all packages.
- Moved grammar directory to dialect and updated all import paths in agent, ai, catalog, and coding-agent packages.

- Consolidated rendering utilities into new dialect/rendering.ts with shared helpers for ChatML, legacy text, and dialect-specific formatting.
- Updated conversation serialization in agent and coding-agent to use dialect.renderTranscript() for native turn envelope rendering.
- Added `jsonSchemaToTypeScript` and `renderToolInventory` to generate tool blocks with TypeScript signatures.

- Changed Harmony invocation rendering to omit `<|constrain|>json` markers in tool call payloads.
- Added compact native tool list-mode inventory rendering with full `# Tool:` output elsewhere.
- agent-loop: raise repetition-detection floor to 180 chars and clear thinking
replay anchors when collapsing a detected loop.
- providers/google: ignore empty text parts, retain terminal thoughtSignatures,
and stop function-call signatures clobbering the prior block.
- autolearn: capture goal-mode at the turn boundary; harden managed-skill writes
against hard-links/symlinks (O_NOFOLLOW + nlink); refuse minting managed skills
whose name an authored skill already claims.
- eager tasks: thread agentKind through the session so a custom top-level agentId
still gets always-mode delegation; split Eager Tasks prompt into hard vs soft.
- title-generator: race the online title model against a local tiny-model fallback.
- eager-todo: keep the soft reminder aligned with the todo init schema.
- mcp/stdio: keep close() detaching the read loop instead of awaiting it.
- stream loop: fix collapsing and tool-call thought-signature handling.
- Added a `personality` enum to `settings-schema.ts` and new `Personality` type alias.
- Replaced inline reply guidelines with a templated `<personality>` block in `system-prompt.md`.
- Added markdown personality specs and wired them into `system-prompt.ts` rendering.
- Updated `sdk.ts` and `selector-controller.ts` to apply personality changes and refresh prompts.
- Set sub-agent sessions to use `personality: none` to suppress personality rendering.
CLAUDE.md, AGENTS.md, GEMINI.md (and the other discovered context-file
flavors) all carry the @-import convention every other agent ships:
`@path/to/file` inside a memory file inlines that file's contents at
launch. The discovery loaders previously read the file content verbatim
and handed it straight to the system prompt builder, so a CLAUDE.md
whose entire body is `@AGENTS.md` shipped a single literal `@AGENTS.md`
line and Claude never saw the project rules.
Added discovery/at-imports.ts implementing the Claude-Code semantics:
relative paths resolve against the importing file's directory, `~/`
expands to home, recursion stops at MAX_AT_IMPORT_DEPTH (5) with cycle
detection, fenced code blocks and inline code spans are opaque so
`npm install @types/node` and `git@github.com` round-trip verbatim, and
missing files keep the literal @-token intact. Wired the expander
into loadProjectContextFiles so every provider that registers under
the context-file capability benefits without per-provider plumbing.
