Our review

Initializes and manages AC Framework spec-driven development workflows using the acfm CLI, including checking status, creating changes, and understanding directory structures.

Strengths

  • Streamlines spec-driven development with a structured directory layout.
  • Provides clear CLI commands for each step (init, new, instructions, status).
  • Supports both new (.acfm) and legacy (openspec) directory structures.
  • Integrates seamlessly with OpenSpec skills.

Limitations

  • Requires the acfm CLI to be installed and configured.
  • Focused on the AC Framework ecosystem; may not apply to other spec-driven approaches.
  • Assumes a specific spec-driven process that may not suit all projects.
When to use it

Use when starting a new project or adding features with the AC Framework to enforce a structured spec-driven development process.

When not to use it

Avoid when the project does not use the AC Framework or when a more flexible/less formal workflow is preferred.

Security analysis

Safe
Quality score95/100

The skill only provides instructions for using the acfm CLI tool to manage local file structures and spec workflows. There are no destructive, exfiltrating, or obfuscated commands. No external network access, no downloading, no sensitive data exposure.

Examples

Initialize project
I'm starting a new Node.js project. Initialize the AC Framework spec workflow using acfm.
Check status
Check the initialization status of this project for the acfm spec workflow.
Create new change
Create a new change called 'user-authentication' in the acfm spec workflow.

AC Framework Spec-Driven Workflow

Guide for initializing and managing spec-driven development workflows using the AC Framework CLI (acfm).

When to use this skill

Use this skill when:

  • Starting a new project and need to initialize the spec workflow
  • Working on an existing project and need to check if specs are initialized
  • Creating a new change/feature using the spec-driven workflow
  • Unsure whether to use .acfm/ or openspec/ directories
  • Need to understand CLI commands for spec management
  • Migrating from legacy openspec/ to new .acfm/ structure

Quick start

# Check if project is initialized
acfm spec status --json

# Initialize new project (creates .acfm/)
acfm spec init

# Create a new change
acfm spec new my-feature --json

# Get instructions for next artifact
acfm spec instructions proposal --change my-feature --json

Directory Structure

NEW (Default): .acfm/ directory

project-root/
├── .acfm/                    # NEW: Default spec directory
│   ├── config.yaml           # Project configuration
│   ├── specs/                # Shared specs
│   └── changes/              # Active changes
│       ├── archive/          # Archived changes
│       └── my-feature/       # Individual change
│           ├── .openspec.yaml
│           ├── proposal.md
│           ├── design.md
│           ├── tasks.md
│           └── specs/

LEGACY: openspec/ directory

project-root/
├── openspec/                 # LEGACY: Still fully supported
│   ├── config.yaml
│   ├── specs/
│   └── changes/

Priority: CLI automatically uses .acfm/ if it exists, otherwise falls back to openspec/.

Instructions

Step 1: Check initialization status

Always start by checking if the project is initialized:

acfm spec status --json

If not initialized ("initialized": false):

  • Proceed to Step 2 to initialize

If initialized ("initialized": true):

  • Note the dirName field (either .acfm or openspec)
  • Proceed to Step 3 to create changes

Step 2: Initialize the project

For new projects:

acfm spec init

This creates:

  • .acfm/config.yaml - Project configuration
  • .acmf/specs/ - Shared specifications
  • .acfm/changes/ - Active changes directory

Legacy support: If the project already has openspec/, it will be detected automatically. No need to migrate unless desired.

Step 3: Create a change

acfm spec new <change-name> --json

Example:

acfm spec new user-authentication --json

Output:

{
  "changeDir": "/project/.acfm/changes/user-authentication",
  "schemaName": "spec-driven",
  "artifacts": ["proposal", "specs", "design", "tasks"]
}

Step 4: Get instructions for artifacts

Each artifact has specific instructions:

# Get instructions for proposal
acfm spec instructions proposal --change <name> --json

# Get instructions for design
acfm spec instructions design --change <name> --json

# Get instructions for tasks
acfm spec instructions tasks --change <name> --json

# Get apply instructions (when ready to implement)
acfm spec instructions apply --change <name> --json

Step 5: Check status

Monitor progress:

# Status of specific change
acfm spec status --change <name> --json

# List all changes
acfm spec list --json

Step 6: Archive completed changes

acfm spec archive <change-name>

CLI Command Reference

Initialization

  • acfm spec init [--json] - Initialize spec directory
  • acfm spec status [--json] - Check initialization status

Change Management

  • acfm spec new <name> [--json] - Create new change
  • acfm spec list [--json] - List all changes
  • acfm spec status --change <name> [--json] - Check change status
  • acfm spec archive <name> [--json] - Archive completed change

Instructions

  • acfm spec instructions <artifact> --change <name> [--json] - Get artifact instructions
  • acfm spec schemas [--json] - List available schemas
  • acfm spec validate <name> [--json] - Validate change structure

Common scenarios

Scenario: New project setup

# 1. Check status
acfm spec status --json

# 2. Initialize
acfm spec init

# 3. Create first change
acfm spec new initial-setup --json

# 4. Get proposal instructions
acfm spec instructions proposal --change initial-setup --json

Scenario: Legacy project (openspec/)

# CLI automatically detects openspec/ directory
acfm spec status --json
# Output: { "initialized": true, "dirName": "openspec", ... }

# Create change in openspec/
acfm spec new legacy-feature --json
# Creates: openspec/changes/legacy-feature/

Scenario: Mixed directories

If both .acfm/ and openspec/ exist:

  • CLI uses .acfm/ (higher priority)
  • Changes are created in .acfm/changes/

To use openspec/ temporarily:

mv .acfm/ .acfm-backup/
# Now CLI will use openspec/

Best practices

  1. Always use CLI commands - Don't manually create directories
  2. Use --json flag for programmatic parsing
  3. Check initialization first - Before creating changes
  4. Let CLI handle paths - Don't hardcode .acfm/ or openspec/
  5. Archive completed changes - Keeps active list clean

Troubleshooting

"Spec system not initialized"

# Solution
acfm spec init

Changes not appearing

# Check which directory is being used
acfm spec status --json
# Look at "dirName" field

# List both directories
ls -la .acfm/changes/ 2>/dev/null || echo "No .acfm/"
ls -la openspec/changes/ 2>/dev/null || echo "No openspec/"

Wrong directory detected

# Force use of openspec/ by renaming .acfm/
mv .acfm/ .acfm-backup/

# Or force use of .acfm/ by renaming openspec/
mv openspec/ openspec-backup/

Requirements

  • AC Framework CLI (acfm) must be installed
  • Node.js >= 18.0.0

Compatibility

  • ✅ Works with both .acfm/ (new) and openspec/ (legacy)
  • ✅ All existing OpenSpec skills continue to work
  • ✅ No migration required for legacy projects
  • ✅ Optional migration path available
