Error message
Warning: Could not read file ${filePath}: ${error.message} What it means
In ContextGatherer._gatherFileContext, each file read is wrapped in a try/catch. If reading or stat-ing a file fails (missing file, permission denied, deleted mid-run), the gatherer does not abort; it emits this console.warn and continues with the remaining files. It is a non-fatal diagnostic indicating one file's context will be missing from the gathered result.

* Generate project file tree contextView on GitHub (pinned to c0c98d367c)
Solutions
- Verify the file exists at the given path (ls / fs.existsSync) and fix the path or restore the file.
- Check file permissions (chmod/chown) so the process user can read it.
- Remove or regenerate stale file references (e.g. re-run the step that produces the file).
- If the file is optional, safely ignore the warning; the gather continues without it.
Example fix
// before: reference to a deleted file files: ['src/config/old-settings.json'] // after: guard existence before gathering const files = ['src/config/settings.json'].filter((f) => fs.existsSync(f));
Defensive patterns
Strategy: validation
Validate before calling
import fs from 'fs';
if (!fs.existsSync(filePath)) {
console.warn(`Skipping missing file: ${filePath}`);
} else if (!fs.statSync(filePath).isFile()) {
console.warn(`Skipping non-file path: ${filePath}`);
} Try / catch
try {
const content = fs.readFileSync(filePath, 'utf8');
} catch (err) {
if (err.code === 'ENOENT' || err.code === 'EACCES') {
// degrade gracefully: continue without this file
} else {
throw err;
}
} Prevention
- Filter file lists with fs.existsSync before passing them to context gathering.
- Resolve paths relative to a validated project root.
- Regenerate or clean stale dependency file lists after refactors/branch switches.
When it happens
Trigger: Calling _gatherFileContext (via fileContextResult) with a filePath that does not exist, has been deleted between dependency detection and reading, is a broken symlink, or is unreadable due to OS permissions.
Common situations: Stale entries in .taskmaster files/deps lists after a refactor or git branch switch; reading generated files that were cleaned; restricted permissions in CI containers; broken symlinks in node_modules-like directories.
