experiment-loop SKILL.md skillA

experiment-loop from event4u-app/agent-config is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add event4u-app/agent-config/experiment-loop@git:20260913.fb3aa4e

Pins git:20260913.fb3aa4e in mdr.lock. Pin the fingerprint instead.

Use to drive a scalar metric down or up across bounded iterations — keep on strict improvement, revert otherwise, state on disk. Triggers 'minimize X', 'optimize until it stops improving'.

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

# experiment-loop

> A bounded **change → commit → evaluate → keep-or-revert** cycle against a
> **scalar metric**, where the decision input is an
> [evaluator-output](../../../docs/contracts/evaluator-output.md) verdict and the
> loop's entire state lives in an append-only register on disk.

This file **routes**. The protocol, the register format, and the pivot ladder are
reference files loaded on demand — a loop doctrine read in full on every session
that merely mentions optimization is a payload nobody asked for.

| Need | Load |
|---|---|
| The iteration protocol and its two exit conditions | [`references/protocol.md`](references/protocol.md) |
| The register's row shape and write ordering | [`references/register-format.md`](references/register-format.md) |
| What to do when the metric stops moving | [`references/pivot-ladder.md`](references/pivot-ladder.md) |

## When to use

* The goal is expressible as **"minimize X"** or **"maximize X"** against a
  mechanical verifier — bundle size, violation count, query count, runtime.
* A verifier already emits, or can be wrapped to emit, the evaluator-output

How to install

The exact contents, by fingerprint
mdr add event4u-app/agent-config/experiment-loop@sha256:02d126698053b8f8

The line at the top of this page pins the label git:20260913.fb3aa4e, 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.
