92%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 production-quality skill body: complete executable Go for the schema and Configure path, concrete operational details throughout, a well-sequenced workflow with explicit validation and error-recovery branching, and clean two-file progressive disclosure verified against the actual bundle. The only weakness is minor — a few motivational/rationale sentences could be trimmed for token efficiency.
Suggestions
Trim the motivational framing (the 'Poor authentication UX is the first thing every user of a provider hits...' sentence and similar rhetoric) — the guidance stands on its own without it.
Condense a few 'why each step matters' bullets (e.g. the secrets-pasted-into-config debugging anecdote) to their one-line technical point to save tokens.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is largely efficient — domain-specific failure-mode reasoning (set-vs-field resolution, sentinel-error design, unknown-value semantics) is knowledge Claude does not have for free, and code blocks carry no boilerplate. A few tokens are trimmable, e.g. the motivational opener 'Poor authentication UX is the first thing every user of a provider hits; a well-designed credential provider chain is what separates a production-grade provider from a demo' and flourishes like 'Collapsing them into one message is how providers end up with users pasting secrets into config to debug'. | 4 / 5 |
Actionability | Both the Schema and Configure examples are complete, compilable Plugin Framework code with real diagnostic strings, attribute paths, and a docs URL; supporting guidance is equally concrete ('chmod 0600', 'info.Mode().Perm()&0o077 != 0', 't.Setenv', 't.TempDir() fixtures', a getenv func field). The only deferred piece — the Chain implementation — is delegated to a complete, verified reference file rather than left as pseudocode. | 5 / 5 |
Workflow Clarity | The Configure workflow is explicitly numbered ('1. Guard against unknown values... 2. Resolve credentials through the chain... 3. Build the client once') with validation checkpoints after each stage ('if resp.Diagnostics.HasError() { return }'), an error-recovery branch on errors.Is(err, credentials.ErrNoCredentials) that selects the right message, and a closing 12-item checklist. The testing section sequences the tests that matter by category. | 5 / 5 |
Progressive Disclosure | A well-signaled 'References (load when needed)' block up front annotates both reference files and what each contains; both exist, are one level deep, and are non-overlapping (complete implementation vs. case studies). The body keeps only the decision-level content and correctly pushes the full chain implementation and tests to references/credential-chain.md, which contains them. | 5 / 5 |
