What Constraint Hardness Testing does

Constraint Hardness Testing checks whether a stated limit is truly hard or just assumed. Use it when someone says a rule, policy, or technical limit cannot be changed and you need to test the source and consequences.

Constraint Hardness Testing is cataloged under AI Engineering on DirSkills. Constraint Hardness Testing comes from a repository tagged claude-code, claude-code-plugin, cognitive-frameworks, creativity and decision-making.

Documentation

README

Excerpt

Constraint Hardness Testing

Organisations accumulate phantom constraints — rules that were real once and calcified, or beliefs that were never tested, or someone's preference that got repeated until it sounded like policy. This skill separates genuine limits from assumed ones before any energy is spent working around or accepting them.

Your Process

Step 1: State the Constraint Write it exactly as it's been stated or assumed. Don't clean it up — the imprecision is often where the phantom lives.

This is the opening of the README. Read the full README on GitHub.
