formula-create SKILL.md skillA

formula-create from stempeck/agentfactory is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add stempeck/agentfactory/formula-create@v1.0.0

Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Create a new agentfactory formula from a description or SKILL.md file. Generates a properly structured TOML formula with steps, dependencies, inputs, and iteration mechanisms. When given a SKILL.md, preserves phase gates as separate formula steps with enforcement language.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Formula Create - Generate agentfactory Workflow Formulas

Create new formulas from natural language descriptions, following agentfactory conventions.

## Usage

```
/formula-create "description of what the formula should accomplish"
/formula-create .claude/skills/<name>/SKILL.md
```

## Examples

```
/formula-create "Review a PR for security vulnerabilities and generate a report"
/formula-create "Convert markdown docs to HTML and deploy to S3"
/formula-create .claude/skills/rapid-implement/SKILL.md
```

## Implementation

When invoked with a description, create a formula following these rules:

### 1. Determine Formula Type

**Use step-based workflow (default)** when:
- Steps have sequential dependencies (output of one feeds into next)
- Work must happen in order
- Iteration/looping may be needed

**Use convoy type** only when:
- Multiple agents can work on the SAME input in parallel
- Each leg examines the input from a different perspective
- A synthesis step combines parallel outputs

### 2. Formula Structure

```toml
description = """
One-sentence summary ending with a period.

Remaining paragraphs describe the workflow overview and expected outcomes.

How to install

The exact contents, by fingerprint

mdr add stempeck/agentfactory/formula-create@sha256:bf1f15f9a9d16007

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
