The instructions are lean with executable commands, but the Overview and 'three production problems' framing ('A full day disappears in restarts', 'developers stop writing them') is motivational padding that could be tightened; it is not a 3 because not every token earns its place, and not a 1 because it avoids explaining basic concepts Claude already knows.

Provides copy-paste-ready commands (e.g., './gradlew runServer -Pdebug=true -PdebugPort=8088', './gradlew test --tests "..." --continuous') and a concrete hot-reload decision table, matching the fully-executable anchor.

The inner loop is sequenced as numbered steps 1–5 with explicit validation checkpoints (breakpoint confirmation 'confirm the breakpoint hits the new line numbers') and an error-handling feedback table, satisfying the clear-sequence-with-validation anchor.

The body is a clear overview with two well-signaled, one-level-deep references (implementation-guide.md and API_REFERENCE.md), both of which are real bundle files, and deeper content is appropriately split out.

Lists multiple concrete actions such as 'attaching an IntelliJ remote debugger to runServer', 'distinguishing changes that hot-reload from changes that force restart', and 'building a GUnit-driven TDD cycle', matching the score-3 anchor; it is not a 2 because the actions are specific and comprehensive rather than partial.

It states what the skill does ('Iterate on Gosu rules and configuration...') and gives an explicit 'Use when' clause covering multiple scenarios, clearly answering both what and when.

Explicit trigger terms like 'guidewire studio', 'gosu hot reload', 'gosu debugger', 'gunit', and 'guidewire runServer' are natural phrases a Guidewire developer would say, matching the good-coverage anchor.

The narrow Guidewire/Gosu/runServer niche and distinct triggers make it unlikely to fire for an unrelated skill; it is well above the somewhat-specific score-2 anchor.
