Converges a comparison of two or more external references into one executable contract with evidence, decisions and acceptance criteria. Use when the result of benchmarking, technology selection or a migration plan will be carried out by someone without this session's context.

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

# recon-to-contract

**Check the shape first**; continue only when both hold:

1. You have ≥2 external references to compare side by side
2. The end point is something that someone else (or your future self, without this session's context) will execute as written

Technology selection, architecture review, competitor benchmarking, migration plans and feature design usually meet both. If only one holds, exit and say which one does not — for pure exploration, bug localization and incremental development, the bottleneck is not the carrier of the conclusions, and for them this process is pure overhead.

By default, write in the user's language.

## Law 1 · Contract

**Context loss is solved by writing a contract, not by writing a document.**

A document needs to be **understood**; a contract only needs to be **executed**. Understanding takes context, execution does not — that is why a contract is immune to context loss.

**Zero-context test** — to judge whether an output is a contract:

> Give it to an executor with no background at all. Can it produce the result directly, without asking a single question?

How to install

The exact contents, by fingerprint
mdr add coder-xieshijie/dev-skills/recon-to-contract@sha256:f8600704a46908ef

The line at the top of this page pins the label git:20261007.d56016d, 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.
