The body is lean (~20 lines) and does not re-explain what RTMS, WebSockets, or media types are — it assumes Claude's competence and every line earns its place, matching the score-3 'lean and efficient' anchor. It is well above score 2, which would require unnecessary explanation or padding.

The steps name concrete subsystems to handle ('event subscription, connection validation, media start, heartbeat, reconnect, shutdown'; 'audio, video, screen share, chat, live transcript, metadata') but provide no executable code, commands, or API specifics — guidance is a structural roadmap rather than copy-paste instructions, matching score 2's 'some concrete guidance but incomplete'. It is more concrete than the vague score-1 anchor but lacks the executable detail of score 3.

The six steps form a clear sequence, but there are no explicit validation checkpoints or feedback loops (no 'verify connection before subscribing' gates), even though WebSocket lifecycle work is fragile. This matches score 2's 'steps listed but validation gaps; checkpoints missing or implicit', falling short of score 3's explicit validate-fix-retry gates.

The body is a clean overview with labeled one-level-deep references, which is good in intent, but scored against the actual bundle only 3 of 7 referenced paths resolve (full-guide, media-types, data-types exist; concepts/, examples/, and troubleshooting/ paths do not), while four real references/ files (connection, environment-variables, quickstart, webhooks) are never linked. Broken paths and undiscoverable files prevent the 'easy navigation' of score 3 and match score 2's 'structure present but not well organized'.

The description 'Use when using RTMS.' names no concrete actions at all — it states only a trigger, never what the skill does (e.g. subscribe, stream, decode media). This matches the score-1 anchor 'Vague or no actions; abstract language' and falls short of score 2, which requires naming a domain and some actions.

Although a 'Use when' clause is present, it is circular ('Use when using RTMS') and the 'what does this do' half is entirely absent, so both halves are missing or very weak per the score-1 anchor. It cannot reach score 2, which at minimum requires a clear statement of what the skill does.

The only keyword is the bare acronym 'RTMS' with no natural-language expansion (e.g. 'Zoom realtime media', 'meeting streams'); a user would be unlikely to say 'using RTMS' verbatim. It is technical jargon with no common variations, matching the score-1 anchor, rather than score 2's 'some relevant keywords'.

'RTMS' is a niche term unlikely to broadly conflict with unrelated skills, but the description is so terse it does not clearly distinguish this skill from sibling Zoom skills like build-zoom-bot or zoom-meeting-sdk-linux that the body itself compares against. It is 'somewhat specific but could still overlap', matching score 2 rather than the distinct-trigger clarity of score 3.
