Lean and well-organized with tables, short sections, and code examples; it assumes Claude's competence and avoids explaining what feature flags or basic concepts are, with code comments earning their place by clarifying skipped-vs-failed behavior.

Provides concrete, executable guidance: real pragmas (`@gate enableViewTransition`), real commands (`/flags --diff <channel1> <channel2>`, `/test www variant false <pattern>`), and specific file paths for adding flags.

Both "Adding a New Flag" and "Debugging Channel-Specific Failures" are clearly numbered sequences, the debugging flow ends with a verification step ("Verify flag exists in all fork files"), and "Common Mistakes" acts as a checklist.

A compact, self-contained skill with no bundle files, organized into clear single-level sections and one well-signaled cross-skill pointer ("See the `flags` skill"), with no nested references.

Lists multiple concrete domain actions such as "flags need updating", "understanding @gate pragmas", "debugging channel-specific test failures", and "adding new flags to React", rather than vague language.

A clear explicit "Use when..." trigger clause is present, but the "what this skill does" is only implied through the trigger scenarios rather than stated as a standalone declarative capability, so it does not fully reach the both-what-and-when bar.

Natural developer-facing terms like "feature flag tests fail", "@gate pragmas", and "channel-specific test failures" match what a user debugging React flags would actually say.

The niche is highly specific (React feature flags, @gate pragmas, www/native-fb channels) with distinct triggers unlikely to conflict with other skills.
