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

Dependency Management

# Create a task that's blocked by another
juno-kanban create "Deploy to prod" --blocked-by ABC123

# Or declare blockers via body markup (auto-parsed)
juno-kanban create "Run integration tests [blocked_by]ABC123, DEF456[/blocked_by]"

# Add/remove dependencies after creation
juno-kanban deps add --id GHI789 --blocked-by ABC123 DEF456
juno-kanban deps remove --id GHI789 --blocked-by ABC123

# Query dependency info for a task
juno-kanban deps ABC123
# Returns: blockers (met/unmet), dependents, priority score

# Find tasks ready to work on (all blockers resolved)
juno-kanban ready
juno-kanban ready --tag backend --limit 5

# Get safe execution order (topological sort)
juno-kanban order
juno-kanban order --scores  # includes priority scores

Body Markup for Dependencies

Dependencies and related tasks can be declared inline in the task body:

# Blockers (all synonyms are equivalent)
[blocked_by]ABC123[/blocked_by]
[block_by]ABC123[/block_by]
[block]ABC123[/block]
[parent_task]ABC123[/parent_task]

# Multiple blockers (comma or space separated)
[blocked_by]ABC123, DEF456[/blocked_by]

# Related tasks (non-blocking references)
[task_id]ABC123[/task_id]

Other Operations

# Get specific task (includes dependency info)
juno-kanban get ABC123

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

# Merge task databases from multiple directories
juno-kanban merge /path/to/source/.juno_task --into ./.juno_task
juno-kanban merge --find-all --into ./.juno_task --dry-run

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

# 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 {}

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

# Create a pipeline with dependencies
juno-kanban create "Write unit tests" --tags backend testing --status todo
# Returns ID: A1b2C3

juno-kanban create "Implement feature" --blocked-by A1b2C3 --tags backend
# Returns ID: D4e5F6

juno-kanban create "Deploy to staging" --blocked-by D4e5F6 --tags devops
# Returns ID: G7h8I9

# See what's ready to work on
juno-kanban ready
# Only A1b2C3 shows — the others are blocked

# Get execution order with priority scores
juno-kanban order --scores
# A1b2C3 (score: 2) → D4e5F6 (score: 1) → G7h8I9 (score: 0)

# Complete first task, check what's unblocked
juno-kanban mark done -ID A1b2C3 --response "Tests written" --commit abc123
juno-kanban ready
# Now D4e5F6 is ready (its blocker A1b2C3 is done)

Team Coordination

# 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:

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 '.'
