This is a well-crafted skill description that clearly identifies a specific technical problem domain (Supabase Realtime disconnections in background tabs), lists concrete actions, and provides explicit trigger guidance. It uses third person voice correctly and includes natural keywords that users experiencing this specific issue would use. The description is concise yet comprehensive.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions: configuring Supabase Realtime clients with worker:true, preventing background tab disconnections, implementing heartbeat monitoring, and reconnection strategies.	3 / 3
Completeness	Clearly answers both 'what' (configures Supabase Realtime clients with worker:true, implements heartbeat monitoring and reconnection strategies) and 'when' (explicit 'Use when...' clause with four specific trigger scenarios).	3 / 3
Trigger Term Quality	Includes strong natural keywords users would say: 'realtime disconnects', 'worker-based realtime', 'heartbeat', 'WebSocket stability', 'browser tab', 'Supabase Realtime', 'reconnection'. These cover multiple natural phrasings a user might use when encountering this problem.	3 / 3
Distinctiveness Conflict Risk	Highly specific niche targeting Supabase Realtime with worker:true configuration and browser tab WebSocket stability. Very unlikely to conflict with other skills due to the precise technology and problem domain.	3 / 3

Implementation

77%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This is a strong, actionable skill with executable TypeScript code covering client configuration, heartbeat monitoring, reconnection with backoff, and channel count safety. The workflow is well-sequenced with explicit validation checkpoints and error recovery loops. The main weakness is that the content is somewhat long for a single SKILL.md and could benefit from splitting detailed implementations into referenced files, and Phase 5 (Integration Test) is vague compared to the otherwise concrete guidance.

Suggestions

Consider moving the detailed code implementations (Phases 2-4) into a referenced file like REALTIME-PATTERNS.md, keeping SKILL.md as a concise overview with the Phase 1 config and pointers to detailed patterns.

Make Phase 5 (Integration Test) more actionable with concrete test code or a test framework example, rather than abstract bullet points describing what to verify.

Dimension	Reasoning	Score
Conciseness	The skill is mostly efficient with executable code examples, but includes some unnecessary verbosity like the Phase 5 integration test section which is vague and adds little value. The pre-conditions section explaining browser/Web Worker requirements is borderline unnecessary for Claude.	2 / 3
Actionability	Every phase includes fully executable TypeScript code with concrete implementations. The code is copy-paste ready with proper imports, file paths, and usage examples. The exponential backoff, heartbeat monitoring, and channel count safeguards are all concretely specified.	3 / 3
Workflow Clarity	The five phases are clearly sequenced from basic configuration through monitoring and testing. Validation is explicit via the verification checklist, and the reconnection logic includes a clear feedback loop (detect error → unsubscribe → backoff → retry). The channel proliferation check acts as a safety gate with hard limits.	3 / 3
Progressive Disclosure	The content is well-structured with clear phases and a verification checklist, but it's a fairly long monolithic file. The instruction to extract utilities into `lib/realtime-utils.ts` is good, but the skill itself could benefit from separating the detailed code implementations into a referenced file while keeping the SKILL.md as a concise overview.	2 / 3
