repairing-project-setup

Use when a repo's agent setup may be broken, half-finished, or drifted - a setting-up-a-project run failed partway, CLAUDE.md or AGENTS.md is thin or missing sections, leftover {{PLACEHOLDER}} text, AGENTS.md is a symlink, the instruction files disagree, or agents behave inconsistently in the repo - audits the project against what setting-up-a-project would generate today and repairs only the gaps, preserving existing content
