Warning: Could not generate project tree

Error message

Warning: Could not generate project tree: ${error.message}

What it means

In ContextGatherer._gatherProjectTreeContext, any error while building the ASCII project tree (directory walk failures, permission errors) is caught and downgraded to this console.warn, with { context: null, breakdown: null } returned so callers skip the tree section. It signals the project tree could not be included in gathered context, not that the whole operation failed.

Solutions

1. Check that the configured project root path exists and is readable.
2. Fix directory permissions (chmod/chown) or run with a user that can read the tree.
3. Reduce directory size/scope or raise the file-descriptor limit (ulimit -n) if EMFILE is the cause.
4. Ignore the warning if the tree is optional; downstream context still works without it.

import fs from 'fs';
if (!fs.existsSync(rootPath) || !fs.statSync(rootPath).isDirectory()) {
  console.warn(`Project tree root invalid: ${rootPath}`);
}

try {
  const tree = generateProjectTree(rootPath);
} catch (err) {
  const tree = null; // proceed without tree section
  console.warn(`Tree generation skipped: ${err.message}`);
}

When it happens

Trigger: Calling _gatherProjectTreeContext (via treeContextResult) when the root directory is unreadable, a subdirectory denies permission, the walker throws (e.g. too many open files, ENOENT on a directory vanishing mid-traversal), or tree-generation code throws for any reason.

Common situations: Running in sandboxes/CI containers with restricted read permissions; huge monorepos hitting EMFILE; directories deleted during traversal; misconfigured rootPath pointing at a non-existent directory.

Understand the failure class

Background: "failed to read file", EACCES, ENOENT and "could not read <path>" errors: when a program can't read a file from disk — this error's family across 49 libraries.
