@promptscript/cli

One source of truth for all your AI coding assistants.

Write AI instructions once in PromptScript, compile to 37 AI coding agents: GitHub Copilot, Claude Code, Cursor, and more.

The Problem

• ❌ 50 repos × 37 AI tools = 1,900 files to keep in sync
• ❌ Security policy update? Manual changes across every repo
• ❌ Switching AI tools? Rewrite everything
• ❌ No audit trail, no inheritance, no validation

The Fix

PromptScript lets you build prompts like code - with inheritance, composition, parameterization, and compilation to any target format.

• ✅ Write once in .prs, compile to all 37 agents
• ✅ Update the source, propagates everywhere automatically
• ✅ Hierarchical inheritance like code, not copy-paste
• ✅ Full validation, audit trail, and version pinning

Quick Start

# Install
npm install -g @promptscript/cli

# Initialize (auto-detects your tech stack)
prs init

# Compile to all configured AI tools
prs compile

Already have CLAUDE.md or .cursorrules?

# Import existing AI instruction file to PromptScript
prs import CLAUDE.md

# Preview the conversion without writing files
prs import .cursorrules --dry-run

# Auto-detect and migrate during project init
prs init --migrate

Example

.promptscript/project.prs:

@meta { id: "checkout-service" syntax: "1.0.0" }

@inherit @company/backend-security
@use @fragments/testing
@use @fragments/typescript-strict

@identity {
  """
  You are an expert Backend Engineer working on the Checkout Service.
  This service handles payments using hexagonal architecture.
  """
}

@shortcuts {
  "/review": "Security-focused code review"
  "/test": "Write unit tests with Vitest"
}

@skills {
  deploy: {
    description: "Deploy service to production"
    userInvocable: true
    allowedTools: ["Bash", "Read"]
  }
}

Run prs compile and get correctly formatted output for every AI tool your team uses.

Commands

Key Features

• Inheritance - build org-wide, team-level, and project-level configs that cascade like CSS
• Composition - reuse fragments across projects with @use
• Parameterized templates - @inherit @stacks/node(port: 8080, db: "postgres")
• Skills - define reusable AI skills with SKILL.md files, resource bundles, and tool permissions
• Multi-target compilation - one source, any number of AI tools
• Watch mode - instant recompilation on file changes
• Overwrite protection - never accidentally clobbers hand-written files
• Validation - catch errors before they reach your AI tools
• Registry support - share configs via Git registries (private or public)
• AI-assisted migration - convert existing CLAUDE.md, .cursorrules, etc.
• Bundled language skill - AI agents learn PromptScript syntax via injected SKILL.md

Supported Targets

Plus 30 more agents (Windsurf, Cline, Roo Code, Codex, Continue, Augment, and others). See the full list.

Detailed Command Usage

Init

prs init [options]

Options:
  -n, --name <name>        Project name (auto-detected)
  -t, --team <team>        Team namespace
  --inherit <path>         Inheritance path (e.g., @company/team)
  --registry <path>        Registry path
  --targets <targets...>   Target AI tools (github, claude, cursor, opencode, gemini, ...)
  -i, --interactive        Force interactive mode
  -y, --yes                Skip prompts, use defaults
  -f, --force              Force reinitialize even if already initialized

Auto-detection: Project name, languages, frameworks, and existing AI tool configurations.

Creates:

• promptscript.yaml - Configuration file
• .promptscript/project.prs - Main project file

Compile

prs compile [options]

Options:
  -t, --target <target>   Specific target (github, claude, cursor, opencode, gemini, ...)
  -a, --all               All configured targets (default)
  -w, --watch             Watch mode for continuous compilation (uses chokidar)
  -o, --output <dir>      Output directory
  --dry-run               Preview changes without writing files
  --force                 Force overwrite existing files without prompts
  --registry <path>       Path or URL to registry
  --verbose               Show detailed compilation progress
  --debug                 Show debug information (includes verbose)

Watch Mode: Uses chokidar for reliable file watching across all platforms. Automatically recompiles when .prs files change.

Overwrite Protection: By default, prs compile protects user-created files from accidental overwriting. Files generated by PromptScript contain a marker (> Auto-generated by PromptScript) and are overwritten silently. For files without this marker:

• Interactive mode: You'll be prompted to overwrite (y/N/a)
• Non-interactive mode: Compilation fails with a list of conflicting files

Use --force to skip all prompts and overwrite everything. Use --dry-run to preview conflicts before writing.

Import

prs import <file> [options]

Options:
  -f, --format <format>   Source format (claude, github, cursor, generic)
  -o, --output <dir>      Output directory (default: .promptscript)
  --dry-run               Preview output without writing files
  --validate              Run roundtrip validation after import

Imports existing AI instruction files (CLAUDE.md, .cursorrules, copilot-instructions.md) into PromptScript format. Uses heuristic classification to map sections to appropriate @identity, @standards, @restrictions, and @knowledge blocks with confidence scoring.

Validate

prs validate [options]

Options:
  --strict                Treat warnings as errors
  --format <format>       Output format (text, json)

Pull Updates

prs pull [options]

Options:
  -f, --force             Force overwrite local files

Show Diff

prs diff [options]

Options:
  -t, --target <target>   Specific target to diff
  --full                  Show full diff without truncation
  --no-pager              Disable pager output

By default, diff output is shown through a pager (less) for easy scrolling. Use --no-pager to disable this behavior. You can customize the pager via the PAGER environment variable.

Check for Updates

prs update-check

Checks if a newer version of the CLI is available on npm and displays the result:

@promptscript/cli v1.0.0
✓ Up to date

Or if an update is available:

@promptscript/cli v1.0.0
Update available: 1.0.0 → 1.1.0 (npm i -g @promptscript/cli)

Automatic Update Checks: The CLI automatically checks for updates once every 24 hours when running any command. The check is non-blocking and cached locally. To disable automatic checks, set the PROMPTSCRIPT_NO_UPDATE_CHECK environment variable:

PROMPTSCRIPT_NO_UPDATE_CHECK=1 prs compile
