93%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.
An exemplary lean, action-oriented skill body: exact error strings, ready-to-run commands, an explicit credential-handling policy, and validation checkpoints on both ends of the login flow. The only notable defect is a formatting flaw — the Verification Step's decision branches collapsed into a single paragraph with literal asterisk bullets, which slightly muddies the workflow's branch logic.
Suggestions
Fix the Verification Step's broken bullet formatting: restore line breaks so 'If the output contains No credentialed accounts...' and 'If an account is listed but the user still receives a 403...' render as two distinct bullets rather than an inline asterisk-laden paragraph.
Clarify what to do when the active account is authenticated but lacks IAM roles, e.g., a concrete check like 'gcloud projects get-iam-policy' or a pointer to the IAM investigation step, to close the loop on the 403/IAM branch.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The ~37-line body is pure operational guidance — exact error strings, three commands, and decision branches — with no concept explanations or padding, matching the lean/every-token-earns-its-place anchor rather than the 4 anchor which requires over-explanation to trim. | 5 / 5 |
Actionability | Guidance is fully concrete and executable: copy-paste ready commands ('gcloud auth list', 'gcloud auth login', 'gcloud auth application-default login'), exact error messages to match against, and explicit directives like 'DO NOT attempt to fix the credentials via code. Credentials must be established by the user.' | 5 / 5 |
Workflow Clarity | The verify -> branch -> correct -> re-verify sequence is present with validation checkpoints ('Before asking the user to log in, independently verify...', 'After the user confirms they have logged in, verify with: gcloud auth list'), but the Verification Step's bullet list lost its line breaks (literal '*' bullets run inline in one paragraph), obscuring the two decision branches and keeping it below a 5. | 4 / 5 |
Progressive Disclosure | This is a simple single-purpose skill under 50 lines with no need for external references; per the rubric's simple-skill guideline, its well-organized sections (Common Error Messages, Verification Step, Corrective Action, Post-Login Verification) qualify for the top anchor. | 5 / 5 |
