td - Task Management for AI Agents

Overview

td is a minimalist CLI for tracking tasks and maintaining agent memory across context windows. When your AI session ends, td captures what was done, what remains, and what decisions were made—so the next session picks up exactly where the last one left off.

Core capability: Run td usage and get everything needed for the next action—current focus, pending reviews, open issues, recent decisions.

Quick Start

Session Start (Every Time)

td usage --new-session  # Auto-rotation + see current state

Output tells you:

• Active work sessions and recent decisions
• What issues are pending review (you can review these)
• Highest priority open issues
• Recent handoffs from previous sessions

Single-Issue Workflow

For focused work on one issue:

td start <issue-id>                    # Begin work
td log "OAuth callback implemented"    # Track progress
td log --decision "Using JWT tokens"   # Log decisions
td handoff <id> --done "..." --remaining "..."  # Capture state
td review <id>                         # Submit for review

Multi-Issue Workflow (Recommended for Agents)

For agents handling related issues:

td ws start "Auth implementation"      # Start work session
td ws tag td-a1b2 td-c3d4             # Associate issues (auto-starts them)
td ws tag --no-start td-e5f6          # Associate without starting
td ws log "Shared token storage"       # Log to all tagged issues
td ws handoff                          # Capture state, end session

Key Workflows

Workflow 1: Starting New Work

# 1. Check what to work on
td usage          # See current state
td next           # Highest priority open issue
td critical-path  # What unblocks most work

# 2. Start work
td start <id>

# 3. Begin logging
td log "Started implementation"

Workflow 2: Handing Off Work

This is critical for agent-to-agent handoffs:

td handoff <id> \
  --done "OAuth flow, token storage" \
  --remaining "Refresh token rotation, error handling" \
  --decision "Using JWT for stateless auth" \
  --uncertain "Should tokens expire on password change?"

Keys:

• --done - What's actually complete (be honest)
• --remaining - What's left (be specific)
• --decision - Why you chose approach X
• --uncertain - What you're unsure about

Next session will see all this context with td usage or td context <id>.

Workflow 3: Reviewing Code

# 1. See reviewable issues
td reviewable

# 2. Check details
td show <id>
td context <id>

# 3. Approve or reject
td approve <id>
# Or:
td reject <id> --reason "Missing error handling"

Important: You cannot approve work you implemented. Session isolation enforces this.

Workflow 4: Handling Blockers

# 1. Log the blocker
td log --blocker "Waiting on API spec from backend team"

# 2. Work on something else
td next              # Get another issue
td ws tag td-e5f6   # Add to work session

# 3. Come back to blocked issue later
td context td-a1b2  # Refresh context when blocker resolves

Commands by Category

Checking Status

Issue Lifecycle

Key Principles

Session Isolation: Every terminal/context gets a unique session ID. The session that implements code cannot approve it. Different session must review. This forces actual handoffs and prevents "works on my context" bugs.

Structured Handoffs: Don't just say "here's what I did"—structure it with done/remaining/decisions/uncertain so next agent has clear context.

Minimal: Does one thing. Single binary, SQLite local storage (.todos/), no server, works with any AI tool.

For AI Agents

Always start conversation with:

td usage --new-session

This auto-rotates sessions and gives you current state. Then:

1. Single focused issue → Use single-issue workflow
2. Multiple related issues → Use td ws start for work sessions
3. Before context ends → Always td handoff or td ws handoff
4. Log decisions → Use --decision flag to explain reasoning
5. Log uncertainty → Use --uncertain flag to mark unknowns
6. Track files → Use td link so future sessions know what changed
