Curl patterns
Before any operation — check server is up
curl -sf http://localhost:8000/api/tasks > /dev/null && echo "OK" || echo "Server not running — run: bun-do start"
Add a task
curl -s -X POST http://localhost:8000/api/tasks \
-H 'Content-Type: application/json' \
-d '{"title": "Buy milk", "date": "2026-03-01", "priority": "P2"}'
Add a recurring payment
curl -s -X POST http://localhost:8000/api/tasks \
-H 'Content-Type: application/json' \
-d '{"title": "Server hosting", "date": "2026-03-01", "priority": "P1", "type": "payment", "amount": "29", "currency": "USD", "recurrence": {"type": "monthly", "day": 1}}'
Find task by title → get ID
curl -s http://localhost:8000/api/tasks | python3 -c "
import sys, json
for t in json.load(sys.stdin)['tasks']:
if 'SEARCH' in t['title'].lower(): print(t['id'], t['title'])
"
Edit (only send fields to change)
curl -s -X PUT http://localhost:8000/api/tasks/TASK_ID \
-H 'Content-Type: application/json' \
-d '{"priority": "P0", "date": "2026-03-15"}'
Mark done
curl -s -X PUT http://localhost:8000/api/tasks/TASK_ID \
-H 'Content-Type: application/json' \
-d '{"done": true}'
Delete
curl -s -X DELETE http://localhost:8000/api/tasks/TASK_ID
Add subtask
curl -s -X POST http://localhost:8000/api/tasks/TASK_ID/subtasks \
-H 'Content-Type: application/json' \
-d '{"title": "Step one"}'
Log project progress
curl -s -X POST http://localhost:8000/api/projects/PROJECT_ID/entries \
-H 'Content-Type: application/json' \
-d '{"summary": "Shipped v1.3 with MCP server and OpenClaw skill"}'
Proactive patterns
Use these patterns for scheduled/autonomous behavior:
Morning briefing: GET /api/tasks, filter for today + overdue, summarize by priority.
End of day: Mark completed tasks done, add entries to active projects.
Weekly review: List all tasks, highlight overdue + P0/P1 without progress.
Payment forecast: List tasks where type=payment, group by month, sum amounts.
Rules
- Always verify the server is running before any API call.
- Never guess IDs — search by title first, then use the UUID.
- Dates must be
YYYY-MM-DD. Resolve "tomorrow", "next Monday", etc. before sending. - Only send fields you want to change on PUT requests.
- The API returns the created/updated object on success.
GET /api/tasksauto-carries overdue non-payment tasks to today.
