70%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 unusually rigorous procedural skill: sequencing, validation checkpoints, failure classification, and reporting are excellent, and guidance is concrete down to exact artifact fields. The costs are token weight — a long monolithic file with a repetitive credential-policy section that should be split into reference files — and deferred CLI specifics.
Suggestions
Move the inference-credential authorization policy (the block spanning 'Before running inference checks' through the waiver rules) and the launchable-e2e.json field contract into one-level-deep reference files (e.g. references/credential-policy.md, references/artifact-contract.md), keeping a short summary and a 'See X' pointer in SKILL.md.
Consolidate the overlapping approval rules in the credential section into a single decision rule (one-commit vs bounded-session vs waiver) to remove repetition.
Include the concrete brev CLI commands for the access and runtime identity checks (environment lookup, state check, image metadata read) instead of only deferring to the brev-cli skill and the e2e shell script.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and imperative with no explanations of concepts Claude already knows, but it could be tightened: the ~27-line inference-credential section repeats overlapping approval, session, and waiver rules ('Obtain explicit authorization before its first exposure', 'Authorization may cover one commit or an explicitly bounded PR validation session', 'Honor existing approvals limited to one commit or run; do not silently convert them...'), matching 'mostly efficient but could be tightened' rather than 'minor instances'. | 3 / 5 |
Actionability | Guidance is highly concrete for an instruction-only skill — exact artifact fields and required values ('candidateSha equal to the selected commit SHA', 'boot.schemaVersion equal to 1'), exact paths ('test/e2e/live/full-e2e.test.ts', 'tools/e2e/brev-launchable-e2e.sh'), and a copy-paste report template — but actual CLI invocations are deferred ('Derive the invocation ... from the current trusted tools/e2e/brev-launchable-e2e.sh implementation') rather than given, so it is mostly executable with minor gaps rather than fully copy-paste ready. | 4 / 5 |
Workflow Clarity | The workflow is clearly sequenced (safety boundaries, result boundary, image evidence, web journey, access/runtime, user journey, handoff, report) with explicit validation checkpoints ('Stop when the artifact is absent, malformed, or belongs to another commit'), error-recovery feedback (the complete pass / failed / partially blocked / not run taxonomy and cleanup verification 'even after a test failure'), and a checklist-style report structure, matching the top anchor. | 5 / 5 |
Progressive Disclosure | The body is well-sectioned with clear headers, but it is a ~190-line monolith with no bundle files at all: the detailed credential-authorization policy and the launchable-e2e.json artifact field contract are inlined content that clearly belongs in one-level-deep reference files, matching 'some structure but content that should be separate is inline' rather than 'most content appropriately placed'. | 3 / 5 |
