The body is lean and explicitly avoids duplicating cs-feat's rules ("不在本文件复制阶段流程、模板或 gate 规则"), with every line earning its place and no padding with concepts Claude already knows.

As an instruction-only delegation skill it provides concrete, specific guidance — load cs-feat as the authoritative protocol by installed name, continue with the entry intent, and stop-and-report on load failure — which is actionable without code per the rubric's instruction-only allowance.

The four numbered execution rules give a clear sequence with an explicit error-recovery checkpoint (rule 4: stop and report if the main protocol cannot load), satisfying the top anchor for a simple, well-organized skill.

Content is appropriately deferred to the authoritative cs-feat skill and its references/ rather than inlined, and the body is cleanly sectioned (执行规则, 维护规则), matching the top anchor for a short, single-purpose skill with no local bundle needed.

Names the domain ("兼容入口"/compatibility entry) and a concrete action ("转交 cs-feat --stage accept"/forwards to cs-feat --stage accept), but it is a single delegation action rather than multiple specific concrete actions, so it does not reach the level-3 anchor.

It states what it does (forwards to cs-feat --stage accept) and implies when ("旧 cs-feat-accept 调用用"/for old calls), but it lacks an explicit "Use when..." clause, which per the judging guidelines caps completeness at 2.

The natural trigger term is the deprecated command name "cs-feat-accept", which is relevant but is technical command syntax with limited coverage of common variations, matching the level-2 anchor rather than broad natural-term coverage.

It carves a clear niche as a deprecated shim that forwards to cs-feat --stage accept and explicitly instructs that new requests should not proactively select it, making it unlikely to trigger for the wrong skill despite the sibling cs-feat relationship.
