# Hook: TaskCompleted
#
# Fires when a task is marked as completed. Reminds Claude to extract
# and store learnings via the mem0 MCP tools.
#
# Input: JSON on stdin with task_id, task_subject, task_description
# Output: Text that becomes feedback to the model (exit 0)
# Intentionally omit -e so the reminder always emits even if identity resolution fails.

Task completed: "$TASK_SUBJECT"
Extract key learnings from this completed task and store them using the mem0 \`add_memory\` tool:
1. What strategy worked well? -> Store with metadata \`{"type": "task_learning"}\`
2. Were there failed approaches before finding the solution? -> Store with metadata \`{"type": "anti_pattern"}\`
3. Were there architectural decisions? -> Store with metadata \`{"type": "decision"}\`
4. Any new conventions or patterns established? -> Store with metadata \`{"type": "convention"}\`
Memories can be as detailed as needed — include full context, reasoning, code snippets, and examples.
Only store genuinely useful learnings — skip if the task was trivial.
Include \`app_id\` = \`"$_PROJECT"\` as a top-level parameter in every \`add_memory\` call (not in metadata).
