Agent Guidelines for Rust Code Quality

This document provides guidelines for maintaining high-quality Rust code. These rules MUST be followed by all AI coding agents and contributors.

Your Core Principles

All code you write MUST be fully optimized.

"Fully optimized" includes:

name	description	license
frontend-design	Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.	Complete terms in LICENSE.txt

This skill guides creation of distinctive, production-grade frontend interfaces that avoid generic "AI slop" aesthetics. Implement real working code with exceptional attention to aesthetic details and creative choices.

The user provides frontend requirements: a component, page, application, or interface to build. They may include context about the purpose, audience, or technical constraints.

-- Declare `@SummaryOfChanges` as variable table, disappear when DB connection session end.
-- Use for storing changes which persisted by transaction.
DECLARE @SummaryOfChanges TABLE(Change VARCHAR(20), id VARCHAR(5), date VARCHAR(8), val INT );

-- Target table is the initial resource of values comparison and changing target of decision of `ON` clauses.
MERGE dbo.[T_target_table] AS T
-- Source value is the input of ours, e.g. input from `user`, `form`, `service`.
USING (VALUES ('97', '2018-03-01')) AS S (src_id, src_date)
-- Condition to find out the fact of data, result of comparison will use for action decision.
ON T.id = S.src_id AND T.date = S.src_date

History Rewriting

Delete the last commit

Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:

git push origin +dd61ab32^:master

1. Add the remote called upstream to your own forked repository.

git remote add upstream https://the-git-repo-url.com/whoseever/whatever.git

2. Fetch all the branches from that upstream remote repository to remote-tracking.

git fetch upstream

3. Make sure that your local repository is checkout as the master branch.
