Make sure to have todo tasks for each step! Do not skip steps!
Ask or confirm user for project path with helpful suggestions. Auto-detect all metadata from project files to minimize user questions.
Use Repomix to package codebase with compression enabled (Tree-sitter). Generate Learning Flow summary by analyzing README and project structure. Keep XML small and focused on usage understanding. Make sure to exclude any tests projects or demo projects, to keep only the target project.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted, and 18 counted toward the lift figure. The other 4 produced results that are not comparable between the two arms, so they are excluded from the headline rather than averaged into it. The headline lift of +32 percentage points is the difference between those two pass rates over the 18 comparable cases. 1 case got worse with the skill loaded, and it is included in that figure.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
