63%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured, largely actionable backend guidelines skill with concrete code patterns and explicit validation checkpoints, weakened by template-filler sections and a monolithic single-file layout with no progressive disclosure. Tightening the trailing boilerplate and splitting reference material into bundle files would lift it further.
Suggestions
Remove the duplicated trailing 'When to Use' section and the generic 'Limitations' boilerplate, and fold the unnumbered 'Resource Guide' into a numbered section to eliminate filler.
Split the BFRI model, architecture pattern library, and naming/observability conventions into separate reference files (e.g., references/bfri.md, references/architecture.md) with clearly signaled links from SKILL.md.
Complete the fragmentary examples — show a full repository method and a runnable test body instead of the stub 'expect(user).toBeDefined()' that references an undefined variable.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The core body is lean rules and code with no beginner-level padding, but it includes unnecessary template filler: a duplicated 'When to Use' section ('This skill is applicable to execute the workflow or actions described in the overview'), generic 'Limitations' boilerplate, and an unnumbered 'Resource Guide' wedged between sections 10 and 11. | 3 / 5 |
Actionability | Provides mostly executable guidance: concrete TypeScript examples for BaseController inheritance, asyncErrorWrapper, Zod parsing ('const input = schema.parse(req.body)'), DI constructors, and unifiedConfig access, with illustrative components explicitly justified ('illustrative application components, not installed dependencies'). Minor gaps remain, e.g., the fragmentary 'await userRepository.findActiveUsers()' and a stub test asserting an undefined 'user'. | 4 / 5 |
Workflow Clarity | A clear pre/post workflow exists: BFRI assessment ('Before implementing or modifying a backend feature, assess feasibility') with a score-to-action table ('Redesign before coding'), hard gates ('No tests → no merge'), and the 'Operator Validation Checklist' ('Before finalizing backend work'). Not a 5 because the middle sections are reference rules rather than explicitly sequenced steps with an error-recovery loop. | 4 / 5 |
Progressive Disclosure | The body is well-sectioned with headers, but ~350 lines are entirely inline with no bundle files: the BFRI model, full architecture pattern library, and naming conventions could each live in separate reference files. Matches 'some structure but content that should be separate is inline'. | 3 / 5 |
