Kanban CLI

Command-line interface for kanban task management

python
from praisonaiagents import Agent

agent = Agent(name="kanban-agent", instructions="Manage kanban boards via CLI.")
agent.start("Show the current kanban board and move completed tasks to Done.")

The user runs praisonai kanban commands to list boards, add tasks, and update status from the terminal.

⚙️ Wrapper Implementation

Quick Start

  1. Install Wrapper

    CLI commands require the wrapper package with kanban implementation:

    bash
    # Wrapper installation (implementation-specific)
pip install praisonai[kanban]  # Example
  2. Basic Usage
    bash
    # List tasks (requires implementation)
praisonai kanban list --status ready

How It Works

CLI commands operate through the KanbanStoreProtocol interface:

Configuration Options

CLI commands use environment variables for configuration:

VariablePurposeDefaultExample
PRAISONAI_KANBAN_BOARDActive board name"default"export PRAISONAI_KANBAN_BOARD=project-a
PRAISONAI_KANBAN_DBDatabase path~/.praisonai/kanban.dbexport PRAISONAI_KANBAN_DB=/custom/kanban.db

Tuning lease & reclamation

VariableDefaultWhat it controls
PRAISONAI_KANBAN_CLAIM_TTL900 (15 min)How long a worker’s claim stays valid before it can be reclaimed
PRAISONAI_KANBAN_STALE_TIMEOUT1800 (30 min)How long a heartbeat can go stale before the worker is treated as hung

Increase PRAISONAI_KANBAN_CLAIM_TTL for long-running tasks. See Kanban Reliability for full details.

Common Patterns

Project Workflow

bash
# Set project board
export PRAISONAI_KANBAN_BOARD=project-a

# Create tasks (requires implementation)
praisonai kanban create "Design login UI" --assignee designer
praisonai kanban create "Implement auth API" --assignee developer

# Link dependencies (requires implementation)
praisonai kanban link design_task api_task

Multi-Agent Coordination

bash
# Human creates high-level task
praisonai kanban create "Build user system" --assignee coordinator

# Coordinator agent breaks it down (via agent tools)
# Worker agents claim and complete subtasks (via agent tools)

# Human monitors progress
praisonai kanban list --status running --json | jq '.tasks[] | .title'

Best Practices

Board Organization

Use separate boards for different projects. Set PRAISONAI_KANBAN_BOARD environment variable to switch between projects efficiently.

Task Naming

Use clear, actionable task titles. Include context and expected outcomes. Example: “Fix login validation error in user service” vs “Fix bug”.

Status Workflow

Follow the standard workflow: todo → ready → running → done. Use blocked for dependencies and review for approval gates.

kanban_runs tool

The kanban_runs tool lists all execution attempts for a specific task, enabling agents to inspect retry history and handoff summaries.

bash
# From agent tool invocation:
kanban_runs --task-id task-abc123

# Outputs:
# run-1: outcome=success, summary="Auth module tests passed", finished_at=2026-06-29T10:00:00Z
# run-2: outcome=failure, summary="DB connection refused", finished_at=2026-06-29T10:05:00Z

CLI example with runs

bash
# Create a task with retry limits
praisonai kanban create "Deploy to staging" --max-retries 3

# Complete with structured handoff
praisonai kanban complete <task-id> --summary "Deployed v2.1.0" --metadata '{"sha": "abc123"}'

# List runs for a task
praisonai kanban runs <task-id>

create

Create a new kanban task.

bash
# Basic task
praisonai kanban create "Implement user authentication"

# With details
praisonai kanban create "Fix login bug" \
  --body "Users can't log in with special characters" \

show

Display detailed task information.

# Show task details
praisonai kanban show task_abc123

# JSON output  
praisonai kanban show task_abc123 --json

Shows task details, comments, and dependency information.

Arguments:

  • task_id: The task ID to display (required)

Options:

  • --json: Output as JSON

move

Move a task to a different status.

bash
# Move to ready
praisonai kanban move task_abc123 ready

# Move to running
praisonai kanban move task_abc123 running

# Move to done
praisonai kanban move task_abc123 done

Arguments:

  • task_id: The task ID to move (required)
  • status: New status (required)

Valid statuses: triage, todo, scheduled, ready, running, blocked, review, done, archived

comment

Add a comment to a task.

bash
# Add progress comment
praisonai kanban comment task_abc123 "Authentication module 50% complete"

# Different author
praisonai kanban comment task_abc123 "Looks good to me" --author reviewer

Child task waits in its current column (todo/blocked) until all parents reach done/archived — then the dispatcher auto-promotes it to ready. See Dependency Auto-Promotion.

Arguments:

  • parent_id: Parent task ID (must complete first)
  • child_id: Child task ID (depends on parent)

Options:

  • --json: Output as JSON
