A Cowork skill for managing project folder structures through conversation. Tell Claude what kind of project you're starting and it builds the whole folder tree for you.

Inspired by Post Haste by Digital Rebellion — a great free app for creating project folder structures from templates. This skill borrows the same idea (and can read Post Haste's .phtemplate format) but works entirely through Cowork. You don't need Post Haste installed to use it.

Want to add a template? See Contributing below.

• Post Haste installed on Mac or Windows: Download free
• CoWork desktop app (Anthropic)
• Python 3.8+ (included with macOS / available on Windows)

1. Download posthaste-skill.skill from Releases
2. Open CoWork
3. Go to Settings → Skills → Install from file
4. Select posthaste-skill.skill

That's it — no configuration needed. The skill auto-detects your Post Haste templates directory.

Once installed, just talk to CoWork naturally:

"Show me my Post Haste templates"
"What templates do I have?"
"List my PostHaste templates"

"Create a new project from my Video Production template, project name Wildlife Doc, client NatGeo"
"Set up project folders for a new commercial shoot"
"New PostHaste project"

"Create a new Post Haste template for podcast episodes"
"I want a template with folders: Raw Audio, Edited, Show Notes, Artwork, Published"

"Show my recent PostHaste projects"
"Where are my projects?"
"Open project #3 in Finder"

The skill reads from (and writes to) this directory automatically. Any template you create through CoWork will appear immediately in the Post Haste app — no restart needed.

Post Haste uses [square_bracket] variables in folder and file names:

Any custom parameter you define in Post Haste preferences can also be used.

The scripts can also be run directly from the terminal:

# List all templates
python3 scripts/read_template.py --list

# Display a specific template's tree
python3 scripts/read_template.py ~/...Templates/VideoProduction.phtemplate

# Create a project (dry run first)
python3 scripts/create_project.py ~/...Templates/VideoProduction.phtemplate \
    ~/Projects project="Wildlife Doc" client="NatGeo" --dry-run

# Create for real
python3 scripts/create_project.py ~/...Templates/VideoProduction.phtemplate \
    ~/Projects project="Wildlife Doc" client="NatGeo"

# List recent projects
python3 scripts/list_projects.py

# Open project #2 in Finder
python3 scripts/list_projects.py --open 2

# Create a new template from a JSON spec
python3 scripts/new_template.py my_spec.json
