Chatcrystal Task Recall

ChatCrystal Task Recall

Use this skill as a thin workflow on top of ChatCrystal Core. Do not invent a parallel memory system in the skill.

Workflow

1. Decide whether the task is substantial enough to justify recall.
2. Trigger for non-trivial implement, refactor, migration, config, investigate, or optimization work.
3. Skip trivial edits, one-line answers, or purely conversational requests.
4. If recall_for_task is available, call it before substantive work with:

• mode: "task"
• task.goal: the concrete task objective
• task.task_kind: the best matching task kind
• task.project_dir and task.cwd when repository context exists
• task.branch when known
• task.related_files or task.files_touched when known
• task.source_agent when the runtime has a stable value

1. Treat project_memories as primary context and global_memories as supplemental context.
2. Apply recalled pitfalls, patterns, and prior decisions before proposing or writing code.

Example MCP Input

Use this shape when calling recall_for_task for implementation or investigation work:

{
  "mode": "task",
  "task": {
    "goal": "Add a paginated notes export endpoint",
    "task_kind": "implement",
    "project_dir": "/path/to/project",
    "cwd": "/path/to/project",
    "branch": "feature/export-notes",
    "related_files": [
      "server/src/routes/notes.ts",
      "shared/types/index.ts"
    ],
    "source_agent": "codex"
  },
  "options": {
    "project_limit": 5,
    "global_limit": 3,
    "include_relations": true
  }
}

Full Mode

Full mode requires ChatCrystal Core plus MCP access to recall_for_task.

• Prefer the current repository or workspace path so Core can derive project_key.
• Surface relevant warnings such as no-project-key or no-matches, but do not treat them as failures.
• If recall returns nothing useful, continue the task normally.

Degraded Mode

If ChatCrystal Core or the MCP tool is unavailable:

• Continue the task without blocking.
• State briefly that long-term recall is unavailable in this environment.
• Do not claim that any memory was recalled.
• Do not instruct the runtime to auto-install ChatCrystal Core as part of the skill flow.
