Metadata Operations

# Set metadata
agkan task meta set <task-id> <key> <value>

# Get metadata
agkan task meta get <task-id> <key>

# List metadata
agkan task meta list <task-id>

# Delete metadata
agkan task meta delete <task-id> <key>

Priority (priority)

Task priority is managed with the priority key:

agkan task meta set <task-id> priority <value>

When to set priority: Priority is set during the planning phase (agkan-planning-subtask), at the same time the task is moved from backlog to ready. This is the responsibility of the planning skill. Skills that select tasks for execution (e.g., agkan-run) read this value to determine which task to work on next.

Tag Priority

When selecting or tagging tasks, use the following priority order:

This is the canonical definition. All skills refer to this table.

JSON Output

Use the --json flag when machine processing is needed:

agkan task list --json
agkan task get 1 --json
agkan task count --json
agkan tag list --json

# Combine with jq
agkan task list --status ready --json | jq '.tasks[].id'

Typical Workflows

Icebox Review (agkan-icebox)

Icebox holds ideas and candidates that are not yet ready for planning. Review them periodically to decide whether to promote or close each one.

# Review icebox tasks
agkan task list --status icebox

# Promote to backlog when requirements become clear
agkan task update <id> status backlog

# Close if no longer needed
agkan task update <id> status closed

Icebox → Backlog conditions:

• Requirements or background are now clear enough to plan
• External blockers have been resolved
• Circumstances have changed and the task is now relevant

Icebox → Closed conditions:

• The need no longer exists
• A duplicate already exists in a later stage
• Superseded by another approach

Receiving Tasks as an Agent

# Check assigned tasks
agkan task list --status ready
agkan task get <id>

# Start work
agkan task update <id> status in_progress

# Complete
agkan task update <id> status done

Structuring Tasks

# Create parent task
agkan task add "Feature Implementation" --status ready

# Add subtasks
agkan task add "Design" --parent 1 --status ready
agkan task add "Implementation" --parent 1 --status backlog
agkan task add "Testing" --parent 1 --status backlog

# Set dependencies (Design → Implementation → Testing)
agkan task block add 2 3
agkan task block add 3 4

# View overall structure
agkan task list --tree

Configuration

Place .agkan.yml in the project root to customize the DB path:

path: ./.agkan/data.db

Or use environment variable: AGENT_KANBAN_DB_PATH=/custom/path/data.db
