ChatCrystal Debug Recall

Use this skill when the task is clearly about diagnosis or debugging. Keep the skill thin and let ChatCrystal Core handle retrieval.

Workflow

1. 1Trigger when the task includes failing tests, compiler errors, runtime exceptions, broken dependencies, environment problems, or performance regressions.
2. 2If recall_for_task is available, call it before proposing a fix with: - mode: "debug" - task.goal: the concrete debugging objective - task.task_kind: "debug" - task.project_dir and task.cwd when known - task.branch when known - task.related_files or task.files_touched when known - task.error_signatures populated with the most useful identifiers available
3. 3Prefer concrete signals such as: - failing test names - exception classes - error codes - log signatures - package or tool versions when they materially affect the failure
4. 4Prioritize returned memories that explain root cause, remediation, or known pitfalls.
5. 5Use recalled memories to sharpen diagnosis, not to skip verification in the current environment.

Example MCP Input

Use this shape when calling recall_for_task for debugging:

{
  "mode": "debug",
  "task": {
    "goal": "Diagnose failing build after TypeScript upgrade",
    "task_kind": "debug",
    "project_dir": "/path/to/project",
    "cwd": "/path/to/project",
    "branch": "upgrade/typescript",
    "related_files": [
      "server/src/cli/mcp/server.ts",
      "tsconfig.base.json"
    ],
    "error_signatures": [
      "TS2322",
      "Type is not assignable"
    ],
    "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.

• Keep project_memories primary and global_memories secondary.
• If the response includes warnings or no-matches, continue debugging normally.
• Do not overfit to a recalled fix when the current failure signature diverges materially.

Degraded Mode

If ChatCrystal Core or the MCP tool is unavailable:

• Continue the debugging task without blocking.
• State briefly that long-term debug recall is unavailable.
• Do not fabricate historical failures, causes, or fixes.
• Do not turn installation commands into automatic skill steps.
