source-command-ledger

Use this skill when the user asks to run the migrated source command ledger.

Command Template

Sprint Ledger

Purpose

View and manage the Sprint Ledger - an append-only data structure that provides global sprint numbering across multiple /plan-and-analyze cycles.

Invocation

/ledger              # Show current status
/ledger init         # Initialize ledger for existing project
/ledger history      # Show all cycles and sprints

Subcommands

/ledger (no arguments)

Shows current ledger status:

Sprint Ledger Status
────────────────────────────────────────
Active Cycle: "Skills Housekeeping" (cycle-002)
Current Sprint: sprint-2 (global: 4)
Next Sprint Number: 5
Archived Cycles: 1
Total Cycles: 2

/ledger init

Initialize ledger for an existing project. Scans grimoires/loa/a2a/sprint-* directories to determine the next sprint number.

Use when: You have an existing Loa project without a ledger and want to enable global sprint tracking.

Example output:

Initialized ledger from existing project
Detected 3 existing sprints, next sprint number: 4

/ledger history

Shows complete history of all cycles and sprints:

Cycle History
─────────────────────────────────────────────────────────────
cycle-001 │ MVP Development      │ archived  │ 2 sprints
          │ Created: 2026-01-10  │ Archived: 2026-01-15
─────────────────────────────────────────────────────────────
cycle-002 │ Skills Housekeeping  │ active    │ 2 sprints
          │ Created: 2026-01-17  │

How It Works

The Sprint Ledger solves sprint number collisions in multi-cycle projects:

1. Global Counter: Every sprint gets a globally unique ID (1, 2, 3...)
2. Local Labels: Users still refer to "sprint-1", "sprint-2" within a cycle
3. Resolution: Commands like /implement sprint-1 resolve to global IDs
4. A2A Directories: Use global IDs (a2a/sprint-4/, not a2a/sprint-1/)

Related Commands

Command	Purpose
/archive-cycle	Archive current cycle and start fresh
/plan-and-analyze	Creates ledger and cycle automatically
/implement sprint-N	Resolves sprint-N to global ID

Workflow

# New project - ledger created automatically
/plan-and-analyze
/architect
/sprint-plan          # Registers sprints in ledger
/implement sprint-1   # Resolves to global sprint-1

# After completing first cycle
/archive-cycle "MVP Complete"  # Archives cycle

# Start new cycle
/plan-and-analyze     # Creates new cycle
/sprint-plan          # sprint-1 now maps to global sprint-3
/implement sprint-1   # Resolves to global sprint-3

Error Handling

Error	Resolution
"Ledger already exists"	Ledger already initialized
"No active cycle"	Run /plan-and-analyze first
"Ledger not found"	Run /ledger init to create
