Usage Guide

Creating Tasks

# Basic task creation
juno-kanban create "Fix authentication bug"

# With tags and status
juno-kanban create "Add user profile page" --status todo --tags frontend ui

# Using --body flag (both formats work)
juno-kanban create --body "Implement OAuth" --tags security backend

Searching & Listing

# List recent tasks (sorted by last modified)
juno-kanban list --limit 10

# Search by status
juno-kanban search --status in_progress

# Search by tags
juno-kanban search --tags backend --tags security

# Search open tasks (no agent response)
juno-kanban search --open

# Search recent tasks
juno-kanban search --recent --limit 5

# Multiple conditions (AND logic)
juno-kanban search --status todo --tags backend --limit 3

Updating Tasks

# Update status
juno-kanban update ABC123 --status in_progress

# Add agent response
juno-kanban update ABC123 --response "Working on OAuth flow"

# Set commit hash
juno-kanban update ABC123 --commit abc123def

# Update tags
juno-kanban update ABC123 --tags urgent backend security

Mark Command (Streamlined Workflow)

# Mark with required response
juno-kanban mark todo -ID ABC123 --response "Ready to start"

# Mark as done with commit (recommended)
juno-kanban mark done -ID ABC123 --response "Feature completed" --commit abc123

# Mark without commit (shows helpful reminder)
juno-kanban mark done -ID ABC123 --response "Bug fixed"
# Output: Consider adding commit hash with --commit flag

Other Operations

# Get specific task
juno-kanban get ABC123

# Archive task (preserves data, sets status to archive)
juno-kanban archive ABC123

# Show help
juno-kanban --help
juno-kanban COMMAND --help

Output Formats

NDJSON (Default)

juno-kanban search --status todo

{"id": "ABC123", "status": "todo", "body": "Fix bug", "tags": ["backend"]}
{"id": "DEF456", "status": "todo", "body": "Add feature", "tags": ["frontend"]}

JSON (Structured)

juno-kanban --format json search --status todo

[
  {"id": "ABC123", "status": "todo", "body": "Fix bug", "tags": ["backend"]},
  {"id": "DEF456", "status": "todo", "body": "Add feature", "tags": ["frontend"]}
]

XML

juno-kanban --format xml search --status todo

Table (Human-readable)

juno-kanban --format table search --status todo

Shell Integration

jq Compatibility

Perfect integration with jq for data processing:

# Extract task IDs
juno-kanban list | jq -r '.id'

# Filter by specific criteria
juno-kanban list | jq 'select(.status == "todo")'

# Count tasks by status
juno-kanban list | jq -r '.status' | sort | uniq -c

# Get tasks with specific tags
juno-kanban list | jq 'select(.feature_tags[]? == "backend")'

# Clean data output (suppress summary)
juno-kanban list 2>/dev/null | jq '.'

Automation Examples

# Daily standup - get your current work
juno-kanban search --status in_progress | jq -r '.body'

# Review completed work with commits
juno-kanban search --status done | jq -r '"✅ \(.body) (\(.commit_hash // "no commit"))"'

# Find urgent tasks
juno-kanban search --tags urgent | jq -r '"⚠️  \(.body)"'

# Git hook integration
git log -1 --format="%H" | xargs -I {} juno-kanban search --commit {}

Configuration

Task Schema

Each task is stored as a JSON object with these fields:

Field	Type	Description
id	string	6-character alphanumeric ID (e.g., "A1b2C3")
status	string	Current status (configurable workflow)
body	string	Task description (supports multiline, code, HTML)
commit_hash	string|null	Git commit hash when completed
agent_response	string	AI/human response or notes
created_date	string	Creation timestamp (YYYY-MM-DD HH:MM:SS)
last_modified	string	Last modification timestamp
feature_tags	string[]	Categorization tags

Example Task

{
  "id": "A1b2C3",
  "status": "done",
  "body": "Implement OAuth2 authentication flow\n\n```python\[e-mail]('/auth')\ndef authenticate():\n    return oauth.redirect()\n```",
  "commit_hash": "abc123def456",
  "agent_response": "Implemented OAuth2 with Google provider. Added tests and documentation.",
  "created_date": "2025-10-22 14:30:00",
  "last_modified": "2025-10-22 16:45:30",

Error Handling

Educational Error Messages

# Invalid tag format
juno-kanban create "Task" --tags "frontend v1"

Validation error: Invalid tag format: 'frontend v1'

Tags can only contain letters, numbers, underscores (_), and hyphens (-).
Found: spaces (not allowed)

Correct format examples:
  --tags backend urgent fix-auth
  --tags frontend_v1 initial feature

Did you mean: 'frontend_v1'?

Status Transition Validation

# Invalid status transition
juno-kanban update ABC123 --status done  # (current: backlog)

Cannot transition from 'backlog' to 'done'.
Allowed transitions from 'backlog': todo, in_progress, archive

Use: juno-kanban update ABC123 --status todo

Examples

Development Workflow

# Morning planning
juno-kanban create "Review pull requests" --tags review daily
juno-kanban create "Fix authentication bug" --tags backend urgent --status todo

# Start working
juno-kanban mark in_progress -ID ABC123 --response "Investigating auth issue"

# During development
juno-kanban update ABC123 --response "Found root cause in JWT validation"

# Complete work
juno-kanban mark done -ID ABC123 --response "Fixed JWT expiry handling" --commit abc123

# End of day review
juno-kanban search --status done | jq -r '"✅ \(.body)"'

Team Coordination

# See what teammates are working on
juno-kanban search --status in_progress | jq -r '"👤 \(.body) - \(.agent_response)"'

# Find tasks needing review
juno-kanban search --status review --tags urgent

# Weekly retrospective
juno-kanban search --status done | jq 'group_by(.commit_hash) | length'

Git Integration

# Link completed tasks to commits
git log --oneline | head -5 | while read commit message; do
  echo "🔗 $commit: $(juno-kanban search --commit $commit | jq -r '.body // "No task linked"')"
done

# Pre-commit hook: ensure task exists
if ! juno-kanban search --status in_progress | grep -q "$(git log -1 --format='%s')"; then
  echo "⚠️  No in-progress task found for this commit"
fi

Troubleshooting

Common Issues

Command not found after installation:

# Ensure pip installed to correct environment
which pip
pip show juno-kanban

# Try reinstalling
pip install -e . --force-reinstall

Slow search performance:

# Install ripgrep for better performance
brew install ripgrep  # macOS
apt install ripgrep   # Ubuntu/Debian

jq parsing errors:

# Ensure you're using recent version (v1.3.0+)
juno-kanban --version

# Use stderr redirection if needed
juno-kanban list 2>/dev/null | jq '.'

Configuration issues:

# Check config file location
ls -la .juno_task/tasks/config.json

# Validate JSON syntax
cat .juno_task/tasks/config.json | jq '.'
