Conversation
thedotmack#1644) When the worker daemon is started from launchd, cron, or nohup, ~/.local/bin is not in PATH, so `uvx` cannot be found and ChromaDB silently fails. Add getUvxPath() utility (mirroring getBunPath()) that checks PATH first, then probes common installation locations including ~/.local/bin/uvx and ~/.cargo/bin/uvx. Use the resolved absolute path when spawning uvx on non-Windows platforms. Falls back to bare 'uvx' if not found anywhere (preserving the previous error message) rather than silently failing with no diagnostic.

In `@src/services/smart-file-read/parser.ts`:
- Around line 105-109: The JS capture for class names in the Tree-sitter query
is using TypeScript's type_identifier and thus misses JS classes; update the js
query string so the class capture uses (class_declaration name: (identifier)
`@name`) `@cls` instead of (class_declaration name: (type_identifier) `@name`)
`@cls`—i.e., locate the query text containing (class_declaration name:
(type_identifier) `@name`) `@cls` in parser.ts and replace type_identifier with
identifier so JavaScript class names are correctly matched.
In `@src/utils/uvx-path.ts`:
- Around line 22-26: The spawnSync call used to probe uvx in getUvxPath
currently has no timeout and can block initialization; modify the spawnSync
invocation in getUvxPath to include a timeout (e.g., 2000 ms) in its options so
the call fails fast, and update the subsequent handling of the result variable
to treat a timeout (check result.error or result.status for timeout/ETIMEDOUT)
the same as other failures so the function falls back correctly; keep the
existing stdio/encoding options and ensure getUvxPath returns the existing
fallback when the probe times out.
- Around line 45-49: The loop that returns a uvx path currently only checks
existsSync(uvxPath) and may return a non-executable file; update the check
inside the uvxPaths iteration to also ensure the path is a regular file and
executable by using fs.statSync or statSync.isFile() and fs.accessSync(uvxPath,
fs.constants.X_OK) (catching access exceptions) before logging and returning;
reference the uvxPaths iteration and the logger debug call so the fix is applied
where existsSync(uvxPath) is used to prevent StdioClientTransport from later
failing to spawn a non-executable file.

🌐 Web query:
tree-sitter-javascript class_declaration grammar node name type
💡 Result:
In tree-sitter-javascript, a class declaration is the named node type class_declaration, and its class name is exposed via the field name, whose node type is identifier:
- Grammar rule:
class_declaration: ... field('name', $.identifier) ...[1] - Static node types:
class_declaration.fields.name.types = [{ type: "identifier", named: true }][2]
So a Tree-sitter query to capture the class name is:
(class_declaration
name: (identifier) `@class.name`)Tree-sitter “field names” like name: come from the grammar’s field(...) annotations. [3]
Sources: [1] [2] [3]
Use JavaScript identifier for class names in the js query.
Line 108 references type_identifier, which is TypeScript-oriented and does not match JavaScript class names. The tree-sitter-javascript grammar defines class declaration names as identifier. This keeps the JS query invalid and silently misses JavaScript class symbols.

Add a timeout to the sync uvx --version probe.
The spawnSync call on line 22 has no timeout. Since getUvxPath() is invoked during service initialization (in ChromaMcpManager), an unresponsive uvx process would block initialization indefinitely. Although the function includes error handling and fallback paths, these don't prevent the hang—they only catch exceptions. Add a timeout to fail fast.
Proposed fix
const result = spawnSync('uvx', ['--version'], {
encoding: 'utf-8',
stdio: ['pipe', 'pipe', 'pipe'],
- shell: false

Validate executability before returning a fallback path.
The code at lines 45–49 checks existence only. A file that exists but lacks execute permissions would be returned and fail later when StdioClientTransport attempts to spawn it. Use accessSync with fs.constants.X_OK and verify it's a file to catch this before returning.

Fixes #1654
Problem
The
QUERIESobject insrc/services/smart-file-read/parser.tsdefined a single"jsts"query used for JavaScript, TypeScript, and TSX files. This query included three TypeScript-only node types:interface_declarationtype_alias_declarationenum_declarationThese node types do not exist in the
tree-sitter-javascriptgrammar. While tree-sitter currently silently ignores unmatched patterns, relying on this behavior is fragile — a future tree-sitter version that strictly validates patterns would silently return zero results for all.jsfile parses (the error handler inrunBatchQuerycatches all exceptions and returns an emptyMap).Solution
Split
"jsts"into two separate queries:"js": JavaScript-only patterns (functions, classes, methods, imports, exports — no TS-only types)"ts": All patterns including TypeScript-specificinterface,type alias, andenumUpdated
getQueryKey()to map:"javascript"→"js""typescript"/"tsx"→"ts"Testing
No behavior change for TypeScript/TSX files. JavaScript files now use only patterns that are valid for the
tree-sitter-javascriptgrammar, eliminating the silent-ignore dependency.
