Ship prompts
like code

Author, version, and publish LLM prompts as packages. Install with the CLI and get type-safe generated code — no copy-paste, no guesswork.

How it works

Three steps from
prompt to production

STEP 01
Author
Write templates with typed Mustache variables. Add docs, output schemas, and metadata.
Hi {{user.name}}{{@type string}} Welcome to {{productName}} {{@outputSchema}}
STEP 02
Configure
Declare prompts with version ranges in sufleur.yaml. The CLI resolves and locks them.
# sufleur.yaml prompts: '@acme/welcome': '^2.0.0' output: typescript
STEP 03
Generate
The CLI fetches templates and generates type-safe code your app imports directly.
$ sufleur add @acme/welcome $ sufleur generate ✓ wrote prompts.ts
The gap

From string concatenation
to a real dependency

app/services/email.tsBefore
// 😬 a string, somewhere in your app const p = `Hello ${name}, welcome to ${product}.` // no types · no version · no validation const res = await llm.chat({ messages: [{ content: p ]} }) const data = JSON.parse(res) // 💥 fingers crossed
Features

Everything you need to
ship prompts like a package

Type-safe codegen
The CLI generates TypeScript & Python with full type inference — no manual types, no runtime surprises.
const { prompt } = welcome.render({ name: 'Ada' // string ✓ })
Draft → Published lifecycle
Iterate on drafts without touching production. Publish when ready — only published versions are installable.
CLI-first DX
One binary, zero config. sufleur add & generate — that's the whole workflow.
Semver versioning
Immutable versions, pinned or ranged — just like npm.
Output schemas
Zod & Pydantic, generated.
Workspaces
Roles for authors & consumers.
AI Agents

Hand the loop to
your coding agent

The CLI ships a skill your agent can load — so it can author, version, and publish prompts on your behalf, end to end.

Ships as a skill
sufleur skill prints a drop-in skill file for Claude Code, Cursor, and any agent.
Drives the full loop
Draft versions, edit files, set schemas, render locally to test — all via the CLI.
Machine-readable
Every command supports --json, so agents act on structured output.
