  "title": "One Skill Too Many: How Co-Installed Skills Conflict in Coding Agents",
  "summary": "The technique replaces reliance on the model's name-and-description-based choice between co-installed similar skills with a pre-tool hook that intercepts the first skill read, plus benchmark scoring of exclusive core functions rather than task completion alone. Cost is low: a hook in the agent harness, an inventory of installed skills with their exclusive core functions, and surfacing which skill ran; no model retraining, extra inference, or additional hardware is required. It can fail if skill metadata is stale or incomplete, if the hook misclassifies legitimate substitutions as conflicts, or if new co-installed skills are added without updating the conflict registry.",
  "rationale": "Skill conflicts silently strip normative constraints such as git-touching bans while tasks still pass, and the proposed hook is cheap to implement on a single-GPU or API-based agent stack with immediate safety and fidelity benefits.",
