prototype SKILL.md skillA

prototype from int2t05/engineering-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add int2t05/engineering-skills/prototype@git:20261015.f440cbb

Pins git:20261015.f440cbb in mdr.lock. Pin the fingerprint instead.

Build a bounded disposable experiment to resolve a specific uncertainty. Triggers on "prototype", "原型".

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

# Prototype

## When to use

- Build a bounded disposable experiment to resolve a specific uncertainty.

**Not for:** implement for production work.

## Steps

1. State one uncertainty, observable criterion and effort bound; choose the simplest runnable form.

2. Implement only what exercises it; label simulated behavior and synthetic data.

3. Run and inspect the experiment against its criterion.

4. Report conclusions in conversation or an approved findings path; retain or remove the prototype according to its actual use.

**Output:** Suggested paths, subject to [human audit](../../../references/human-audit.md): `docs/design/prototype-findings.md` when conclusions need persistence.

## Verify

- The experiment was run and narrows its question; simulated behavior is not presented as real integration.

## References

- [engineering-principles.md](../../../references/engineering-principles.md) — shared decision boundaries, scope and verification.
- [design-principles.md](../../../references/design-principles.md) — design discipline (hierarchy before decoration, design every state, recognize rather than recall).

How to install

The exact contents, by fingerprint
mdr add int2t05/engineering-skills/prototype@sha256:8b552c03f2b2f284

The line at the top of this page pins the label git:20261015.f440cbb, 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.
