The description names the domain (terminal activity monitoring) and some actions (watch, observe, react), but doesn't list specific concrete capabilities like logging commands, detecting error patterns, or providing real-time suggestions.

Clearly answers both 'what' (watch, observe, react to human terminal activity) and 'when' with an explicit 'Use when' clause and multiple example trigger phrases covering different use cases.

Includes strong natural trigger terms users would actually say: 'monitor the terminal', 'watch what the user is doing', 'audit terminal activity', 'errors', 'security issues', 'provide help'. Good coverage of variations.

The focus on monitoring/watching human terminal activity is a clear niche that is unlikely to conflict with other skills. The combination of 'terminal', 'monitor', 'watch', and 'audit' creates a distinct trigger profile.

The skill is reasonably well-written but includes some unnecessary elaboration. Sections like 'Monitoring is only useful if you know what to look for' and explanations of what polling vs event subscription are could be tightened. The calibration principles and pitfalls sections, while useful, contain advice Claude likely already understands (e.g., don't be noisy, respect privacy). However, the domain-specific patterns and recipes earn their tokens.

The skill provides good conceptual guidance with concrete pattern examples (error strings to match, dangerous commands to intercept) and visual recipes using box-drawing characters. However, it lacks executable code — the pseudocode blocks ('read screen / analyze what changed / respond if needed') are not copy-paste ready, and the event subscription approach is described abstractly without concrete implementation. The recipes show desired output but not the actual API calls or tool invocations to produce them.

The two approaches (polling vs event subscription) are clearly distinguished, and the polling loop is sequenced. However, there are no explicit validation checkpoints — for example, no guidance on verifying that overlays rendered correctly, that event subscriptions are active, or how to handle connection failures. The recipes show what to do but not how to verify it worked or recover from failures.

The skill references other skills ('see the wsh:visual-feedback skill', 'see the core skill for connection mechanics') which is good progressive disclosure. However, with no bundle files provided, these references are unverifiable. The document itself is quite long (~250 lines) and some sections (like the full list of monitoring recipes) could potentially be split into a separate reference file. The overall structure with clear headers is good but the content is somewhat monolithic.
