axross / skills

Every task that touches a project—implementing, refactoring, diagnosing failed checks, running a project command, or writing a pull request body. The baseline discipline underneath specialized skills: keep changes scoped, run the format and lint loop, map what the change puts at risk, and find out how the project is actually run. Applies even when the request never mentions formatting, linting, comments, dependencies, docs, or descriptions, and when you need one of the project's operations—tests, dev server, build, lint, deploy—and must find it documented or ask. Change-loop practices own progression after results; the conduct baseline applies when a session touches nothing.
