Warning: Could not load tasks for ContextGatherer: ${error.m

Error message

Warning: Could not load tasks for ContextGatherer: ${error.message}

What it means

ContextGatherer._loadAllTasks reads the tasks file via readJSON and returns [] with this warning if reading or parsing fails. The gatherer then operates with no tasks, so context gathering yields empty results rather than crashing the host command.

Solutions

1. Run `task-master init` or create the tasks file if it's missing
2. Validate/repair JSON syntax in .taskmaster/tasks/tasks.json
3. Confirm the tag exists (task-master tags) or omit the tag option
4. Re-run from the actual project root

Example fix

// before
{ "tasks": [ { "id": 1, "title": , } ] }
// after
{ "tasks": [ { "id": 1, "title": "Valid entry" } ] }

import { existsSync } from 'fs';
const tasksPath = '.taskmaster/tasks/tasks.json';
if (!existsSync(tasksPath)) {
  console.error('tasks.json missing — run task-master init before using ContextGatherer');
} else {
  try { JSON.parse(readFileSync(tasksPath, 'utf8')); } catch { console.error('tasks.json is not valid JSON'); }
}

function isLoadableTasksFile(data) {
  return data !== null && typeof data === 'object' && Array.isArray(data.tasks);
}

const gatherer = new ContextGatherer(projectRoot, tag);
const tasks = gatherer._loadAllTasks();
if (tasks.length === 0) {
  console.warn('ContextGatherer loaded 0 tasks — check for the load warning above');
}

When it happens

Trigger: Constructing a ContextGatherer when readJSON(tasksPath, projectRoot, tag) throws — tasks.json missing, invalid JSON, wrong --tag referenced, or unreadable path.

Common situations: Running context-dependent commands before task-master init; corrupted tasks.json after a crash; passing a tag name that has no data; wrong project root cwd.
