Todoist API

Todoist CLI Skill

This skill provides procedural guidance for working with Todoist using the td CLI tool.

Prerequisites

The td CLI must be installed and authenticated. Verify with:

td auth status

If td is not installed or not authenticated:

• Not installed: Tell the user to install with npm install -g @doist/todoist-cli
• Not authenticated: Tell the user to run td auth login to authenticate via OAuth

Output Formats for Agents

For machine-readable output, use these flags:

• --json - Output as JSON array
• --ndjson - Output as newline-delimited JSON (one object per line)
• --full - Include all fields in JSON output (default shows essential fields only)

Confirmation Requirement

Before executing any destructive action, always ask the user for confirmation using AskUserQuestion or similar tool. A single confirmation suffices for a logical group of related actions.

Destructive actions include:

• Deleting tasks, projects, sections, labels, or comments
• Completing tasks
• Updating existing resources
• Archiving projects

Read-only operations do not require confirmation.

Quick Commands

Quick Add Examples

td add "Buy milk tomorrow p1 #Shopping"
td add "Call dentist every monday @health"
td add "Review PR #Work /Code Review"

The quick add parser supports:

• Due dates: tomorrow, next monday, Jan 15
• Priority: p1 (urgent) through p4 (normal)
• Project: #ProjectName
• Section: /SectionName
• Labels: @label1 @label2

Pagination

For large result sets, use --all to fetch everything, or handle pagination with cursors:

# First page
result=$(td task list --json --limit 50)

# If there's a next_cursor in the response, continue
cursor=$(echo "$result" | jq -r '.[-1].id // empty')
td task list --json --limit 50 --cursor "$cursor"

Reference Resolution

The <ref> parameter in commands accepts:

• Task/project/label name (partial match supported)
• id:xxx for exact ID match
• Numeric ID (interpreted as id:xxx)

Workflow Summary

1. Verify authentication - td auth status
2. Read operations - Execute directly without confirmation
3. Write operations - Ask for confirmation before executing
4. Use JSON output - Add --json flag for machine-readable data
5. Handle large datasets - Use --all or pagination with --cursor
