formula-authoring SKILL.md skillA
formula-authoring from a5c-ai/babysitter is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Author TOML-based Formula workflow templates that become Protomolecules and active Molecules in Gas Town's durable workflow system.
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
- Creating multi-step processes with variable binding - Building workflows that must survive restarts - When NDI (Nondeterministic Idempotence) is needed ## Process 1. **Define** formula steps and variables in TOML format 2. **Validate** formula structure and dependencies 3. **Cook** into protomolecule (resolve variables, freeze) 4. **Test** by instantiating a trial molecule 5. **Register** in the formula library for reuse ## Formula Lifecycle ``` Formula (TOML template) -> Protomolecule (frozen) -> Molecule (active, durable) ``` ## Key Concepts - **Formula**: TOML-based workflow template with variables - **Protomolecule**: Frozen template ready to instantiate - **Molecule**: Active durable workflow surviving restarts - **NDI**: Nondeterministic Idempotence - useful outcomes from unreliable processes ## Tool Use Invoke via babysitter process: `methodologies/gastown/gastown-molecule`

How to install
mdr add a5c-ai/babysitter/formula-authoring@sha256:dcbd2ec68b02d814The line at the top of this page pins the label git:20260601.da7723a, 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.
