Things3

What I do

This skill provides scripts to interact with Things3 (task management application) and retrieve data in CSV format.

Available Scripts

Get Areas - Retrieve areas from Things3 with optional filtering.

~/.config/opencode/skill/things/get-areas [ids=id1,id2] [name=searchterm] [tags=tag1,tag2]

Get Projects - Retrieve projects from Things3 with optional filtering.

~/.config/opencode/skill/things/get-projects [ids=id1,id2] [name=searchterm] [area_ids=aid1,aid2] [tags=tag1,tag2]

Get Project - Retrieve detailed information for a single project by ID, including all to-dos/items within the project.

~/.config/opencode/skill/things/get-project <project_id>

Get To-do - Retrieve detailed information for a single to-do by ID.

~/.config/opencode/skill/things/get-todo <todo_id>

Set To-do - Update a to-do's properties (name, status, notes, and/or tags).

~/.config/opencode/skill/things/set-todo <todo_id> [name=...] [status=...] [notes=...] [tag_names=...]

When to use me

Use me when you need to work with the Things3 Tasks application (aka Things). This skill allows you to interact with Things3 to retrieve and filter your areas and projects.

Filter Options

All filters are optional and can be combined. Multiple filters use AND logic (must match all), while values within a filter use OR logic (match any).

get-areas Filters

• ids - Comma-delimited area IDs (whitespace trimmed)

  • Example: ids=RnYsrXCAB2VZCvqkKBeVty or ids="id1, id2, id3"

• name - Case-insensitive substring search in area name

  • Example: name=work or name="Personal Projects"

• tags - Comma-delimited tag names (whitespace trimmed, exact match)

  • Example: tags="Work: Provider Nexus" or tags="tag1, tag2"

get-projects Filters

• ids - Comma-delimited project IDs (whitespace trimmed)

  • Example: ids=2SwCCY2WDAKqksu6oufbwb or ids="id1, id2, id3"

• name - Case-insensitive substring search in project name

  • Example: name=camera or name="ops prime"

• area_ids - Comma-delimited area IDs (whitespace trimmed)

  • Example: area_ids=K9U3dAEXnchmJTTCQLput5 or area_ids="aid1, aid2"

• tags - Comma-delimited tag names (whitespace trimmed, exact match)

  • Example: tags="Important" or tags="tag1, tag2"

set-todo Parameters

Required:

• <todo_id> - The to-do ID (first positional argument)

Optional (at least one required):

• name="new name" - Update the to-do name
• status=open|completed|cancelled - Update status (must be one of these three values)
• notes="note text" - Update notes
• tag_names="tag1; tag2; tag3" - Set tags (semicolon-separated, replaces all existing tags)
