Wire fire-and-forget PostHog telemetry into every lifecycle hook (session_start, stop, pre_compact, task_completed, user_prompt, post_tool_use) matching the same project key, endpoint, and payload structure used by the Python SDK, CLI, and OpenClaw. - 10% sampling on ALL events to keep PostHog costs predictable - Anonymous distinct_id: MD5(api_key) or SHA-256(username) - Opt-out via MEM0_TELEMETRY=false - Platform detection: Claude Code / Cursor / Codex - Never sends user content, API keys, or raw identifiers - 16 new tests (110 total passing)

Before finishing, check if there are important learnings from this interaction that should be persisted using the mem0 `add_memory` tool:
|
|
|
|
1. Were any significant decisions made? -> Store with metadata `{"type": "decision"}`
|
|
2. Were any new patterns or strategies discovered? -> Store with metadata `{"type": "task_learning"}`
|
|
3. Did any approach fail? -> Store with metadata `{"type": "anti_pattern"}`
|
|
4. Did you learn anything about the user's preferences? -> Store with metadata `{"type": "user_preference"}`
|
|
5. Were there environment/setup discoveries? -> Store with metadata `{"type": "environmental"}`
|
|
|
|
Memories can be as detailed as needed — include full context, reasoning, code snippets, file paths, and examples. Longer, searchable memories are more valuable than vague one-liners.
|
|
|
|
If nothing notable happened in this interaction, it's fine to skip. Only store genuinely useful learnings.
|
|
|
|
Always include `app_id` (the active project_id from SessionStart) as a top-level parameter in every `add_memory` call.
