Each entry is a complete HARNESS.md file, written so that a harness can be built from the file alone. Save one in your project root, tell your coding agent what the project is for, and have it check the Context section against your project before it builds.

exploratory-prototype
A deliberately thin agent harness for an exploratory prototype, proof of concept, demo, spike, or research experiment: one person, a coding agent supervised turn by turn, code that is thrown away or redesigned within a quarter, and nothing a wrong change can damage. Keeps only what still matters when everything else is disposable: isolation from host credentials, a secret scan, one command that runs the thing, a smoke check, and checkpoint commits. States the triggers for moving to a heavier design.

production-engineering
A full agent harness for a production codebase maintained by a team for years, where a wrong change can reach users, data, or money, and coding agents work task by task with review in between or partly unattended. Hosted on GitHub or GitLab. Covers all seven layers: an isolated environment with scoped credentials and a tool inventory, a short entrypoint with routed knowledge files, fast and full verification an agent can run itself, pre-commit and CI gates behind one summary check, a written permission policy with a protected default branch and squash merges, specification-driven completion with recorded approval, and drift control with a harness self-check.

solo-open-source-library
A medium-weight agent harness for a public open-source library with one maintainer who accepts outside contributions: a long-lived package whose public API other projects depend on, hosted on GitHub or GitLab, where issues and pull requests bring in text and code anyone can write. Lets a contributor's coding agent succeed without the maintainer, protects against prompt injection from public content, gates the public API with a snapshot, semantic versioning, and a changelog, asks for a short proposal only when the API changes, and keeps ceremony low everywhere else.
