{"slug":"api-compatibility-classifier","source_name":"api-compatibility-classifier","name":"API Compatibility Classifier","description":"Classifies each change in a public-surface diff (function signature, REST request/response schema, or library API) as breaking, additive, or internal by concrete rules — including the input-vs-output asymmetry that flips the verdict — then derives the semver bump for the release, applying the 0.x pre-1.0 rule. Use when someone hands you a diff of a published API and asks whether it breaks callers or what version the next release should be. Do NOT use for generating a changelog from commit messages, for reviewing a third-party dependency version bump, or for reviewing application source code for bugs.","version":1,"lift":{"pass_rate_delta_pts":null,"pass_rate_pct":20,"total_cases":15,"passed_cases":3,"tokens_delta_pct":603.5,"turns_delta_pct":0,"verdict":"mixed","benchmark_model":"gemini-3.5-flash","grading_method":"judged","completed_at":"2026-07-11T04:14:35.068119+00:00"},"skill_score":null,"benchmark_models":[{"model":"gemini-3.5-flash","headline":false,"delta_pts":null,"with_pass_pct":null,"without_pass_pct":null,"tokens_delta_pct":603.5,"turns_delta_pct":0,"total_cases":15,"cases_aggregated":15,"verdict":"mixed","never_hurt":true,"completed_at":"2026-07-11T04:14:35.068119+00:00","run_id":"3961c18e-66ff-457f-8be5-e59d1e7943ff","version_number":1,"is_latest_version":true,"gate":"not_comparable"}],"trust":{"skill_safety":"passed","safety_status":"clean","intent_verdict":"safe","content_status":"clean","indexable":false},"license":null,"install_count":0,"manifest_hash":"e7debe8dba416bab62680e24f6bfdf5974d0332d3bf2ecde6b3718768a85185c","raw_url":"https://app.decimal.ai/s/api-compatibility-classifier/SKILL.md","scorecard_url":"https://app.decimal.ai/skills/api-compatibility-classifier"}
