AC State Tracker

Persistent state management for cross-session autonomous coding.

Overview

Maintains all state across sessions:

• Feature list tracking (passes: false → true)
• Execution state (iteration, cost, status)
• Progress logging
• Handoff packages
• Checkpoint management

Quick Start

Initialize State Tracker

from scripts.state_tracker import StateTracker

state = StateTracker(project_dir)
await state.initialize()

Save/Load State

# Save current state
await state.save()

# Load state from files
current_state = await state.load()

Update Feature Status

# Mark feature as passing (IMMUTABLE: false → true only!)
await state.update_feature("auth-001", passes=True)

feature_list.json Schema

{
  "features": [
    {
      "id": "auth-001",
      "description": "User registration endpoint",
      "category": "authentication",
      "status": "completed",
      "passes": true,
      "test_cases": [
        "User can register with email",
        "Validation errors shown"
      ],
      "dependencies": [],

      "actual_effort": "2.5h",
      "started_at": "2025-01-15T10:00:00Z",

    }
  ],
  "total": 50,
  "completed": 25,
  "in_progress": 1,
  "blocked": 0
}

CRITICAL RULE: Features can ONLY transition passes: false → true. Never delete or edit features - this prevents the agent from "solving" by removing tasks.

Operations

1. Initialize State

state = StateTracker(project_dir)
await state.initialize()

# Creates default files if not exist
# Loads existing state if present

2. Update Feature

# Mark feature complete
await state.update_feature(
    feature_id="auth-001",
    passes=True,
    actual_effort="2.5h"
)

# Mark feature in progress
await state.update_feature(
    feature_id="auth-002",
    status="in_progress"
)

3. Create Checkpoint

checkpoint = await state.create_checkpoint(
    name="before-refactor",
    git_commit=True
)
# Returns checkpoint ID for rollback

4. Restore Checkpoint

await state.restore_checkpoint("checkpoint-20250115-100000")
# Restores feature_list.json and git state

5. Log Activity

await state.log_activity(
    action="CONTINUE",
    details="Implementing login endpoint",
    iteration=12
)
# Appends to autonomous-log.jsonl

6. Save Handoff

await state.save_handoff({
    "current_feature": "auth-002",
    "context_summary": "Completed auth, starting profile...",
    "next_action": "Implement profile page"
})

7. Get Progress Summary

progress = await state.get_progress()
# Returns:
#   completed: 25
#   total: 50
#   percentage: 50%
#   current_feature: "auth-002"
#   estimated_remaining: "4 hours"
