PromptG CLI

PromptG makes managing, editing and rendering dynamic AI prompts on the fly effortless

• Create/manage/edit collections of prompts easily
• Runs from command line, can pipe into anything.. e.g. ollama, CI, git hooks
• Render variations of prompts on the fly, inject {{variables}} or inject files.. e.g. git diffs or documents
• Can store prompts globally ~/.promptg/ or in projects .promptg/, run anywhere

Quickstart

# Install
npm install -g @promptg/cli


# Create a prompt, paste in text
promptg prompt new my-prompt

# Or pipe to create, + add dynamic variables
echo "Review this {{lang}} source code: {{code}}. Suggest improvements." | promptg prompt save code-review

# Render a simple text prompt
promptg get my-prompt

# Render with dynamic values, insert files
promptg get code-review --var lang=Python --var [email protected] | ollama run mistral

# Create a prompt store in your project, share with others/team (.promptg/)
promptg init

The .promptg/ folder

Your global prompts get stored in ~/.promptg/, you can run these anywhere.

To set up a local repo in a project, just run the init command

promptg init

It creates a project store at .promptg/ with this structure:

.promptg/
|---- prompts/                 # Prompt documents
|---- templates/               # Prompt templates
`---- packs/                   # Bundles of prompts

PromptG autodetects this and picks up prompts in the project.

• The prompts are part of the code, other developers/team members can run the same prompts
• Add a .promptg/ folder to your work or Open Source project to guide contributors and help maintain consistency
  • pre-pr-check A prompt of things you want checked before devs raise a PR (tests, docs, breaking changes check, changelog, screenshots, etc.)
  • new-feature A prompt to guide/shape new features, specifying conventions or constraints
  • update-documentation Provide structure to help devs add to documentation in a way that conforms to project
  • changelog/release-notes-writer Help generate these in a repeatable and consistent way.

Prompt files

Prompts are stored in the .promptg/ folder as json files.

Editing JSON sucks - The CLI always lets you work in plain text.

The files are in JSON to allow storage of extra structured data, like default template values, and allow further extension.

{
  "schemaVersion": "1",
  "kind": "prompt",
  "name": "review",
  "content": "Review this {{language}} code, emphasis on {{focus}}.\n\n Here is the code:  {{diff}}",
  "defaults": {
    "language": "Python",
    "focus": "Security"
  }
}

Packs

PromptG lets you package up prompts into packs that you can share and install.

# Share
promptg pack build my-pack --pack-version 1.0.0
promptg pack install ./path/to/pack.json (or URL)

Packs are versioned bundles of prompts you can share via URL or file.

See PromptG Starter Packs for examples.

Other CLI features

• Clean stream separation: machine output to stdout, status/warnings/errors to stderr (--quiet suppresses status).
• First-class JSON mode: --format json / --json returns structured envelopes (ok/data/warnings + ok=false/error{code,message,details}), including --help / --version.
• Stable exit codes: 0 success, 1 validation/runtime, 2 usage, 130 canceled.
• Debuggable failures: --debug adds stack/cause into JSON details (and prints stack in text mode).
• Pipeline-friendly: prompt save reads from stdin; render prints prompt text by default.
• Store scopes: --store auto|project|global with project auto-detect (.promptg/) + fallback behavior.
• Reliability/CI: atomic writes, validate command that exits non-zero on issues, plus doctor diagnostics with JSON output.
