Objective

Objective Skill

Overview

Objectives are coordination documents for goals requiring multiple plans/PRs to complete. Unlike erk-plans (single executable implementations), objectives track progress across related work and capture lessons learned along the way.

Scope range:

• Small: Feature requiring 2-3 related PRs
• Medium: Refactor spanning several plans
• Large: Long-running strategic direction emitting many plans

Objective vs Erk-Plan

Key Design Principles

1. Human-first - Plain markdown, no machine-generated metadata
2. Incremental capture - Each action gets its own comment
3. Lessons as first-class - Every action comment includes lessons learned
4. Clear roadmap - Status visible at a glance in the body
5. Body stays current - Update body when roadmap status changes
6. Steelthread-first - Each phase starts with minimal vertical slice proving the concept works
7. One PR per phase - Each phase is sized for a coherent single PR
8. Always shippable - System remains functional after each merged PR
9. Body is source of truth - Body always contains complete current state; comments are the changelog
10. Two-step for all changes - Every addition (context, decisions, phases) gets a comment AND body update
11. Context over code - Provide references to patterns, not prescriptive implementations
12. Session handoff ready - Body should be self-contained for any session to pick up and implement

Quick Reference

Creating an Objective

gh issue create --title "Objective: [Title]" --label "erk-objective" --body "$(cat <<'EOF'
# Objective: [Title]

> [1-2 sentence summary]

## Goal

[What success looks like - concrete end state]

## Design Decisions

1. **[Decision name]**: [What was decided]

## Roadmap

### Phase 1: [Name] Steelthread (1 PR)

Minimal vertical slice proving the concept works.

| Step | Description | Status | PR |
|------|-------------|--------|-----|
| 1.1 | [Minimal infrastructure] | pending | |
| 1.2 | [Wire into one command] | pending | |

**Test:** [End-to-end acceptance test for steelthread]

### Phase 2: Complete [Name] (1 PR)

Fill out remaining functionality.

| Step | Description | Status | PR |
|------|-------------|--------|-----|
| 2.1 | [Extend to remaining commands] | pending | |
| 2.2 | [Full test coverage] | pending | |

**Test:** [Full acceptance criteria]

## Current Focus

**Next action:** [What should happen next]
EOF
)"

Logging an Action

Post an action comment after completing work. See format.md for full template.

gh issue comment <issue-number> --body "$(cat <<'EOF'
## Action: [Brief title]
**Date:** YYYY-MM-DD | **PR:** #123 | **Phase/Step:** 1.2
### What Was Done
### Lessons Learned
### Roadmap Updates
EOF
)"

After posting, update the issue body (roadmap statuses, "Current Focus").

Spawning an Erk-Plan

To implement a specific roadmap step, create an erk-plan that references the objective:

erk plan create --title "Implement [step description]" --body "Part of Objective #123, Step 1.2"

Workflow Summary

1. Create objective - When starting multi-plan work
2. Log actions - After completing each significant piece of work
3. Update body - Keep roadmap status current
4. Spawn erk-plans - For individual implementation steps
5. Close - When goal achieved or abandoned (proactively ask when all steps done)
