71%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, actionable body with concrete VTC/VCL examples, run commands, and CI integration, whose main defect is a grace-mode example that cannot pass as written. Progressive disclosure is the weakest area: everything is inlined in one long file with no reference bundle to split per-topic detail into.
Suggestions
Fix the grace-mode VTC by including the vcl_deliver logic that sets resp.http.x-cache = "GRACE" inside the embedded -vcl+backend block (or drop the x-cache assertion).
Add a matching VTC example for the xkey surrogate-key section, which currently shows only VCL with no test.
Move the full worked examples (PURGE, grace, xkey) into per-topic files under references/ and keep SKILL.md as an overview with clearly signaled links, enabling one-level-deep progressive disclosure.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Largely efficient with tables and lean commands ('apt install varnish', anti-patterns table), but the grace VCL appears twice and the References section repeats links already cited inline, so a few tokens could be trimmed. | 4 / 5 |
Actionability | Provides mostly copy-paste-ready material (full VTC anatomy, PURGE VCL+VTC, run commands, CI yaml), but the grace-mode VTC asserts 'expect resp.http.x-cache == "GRACE"' without any vcl_deliver setting that header, so it fails as written, and the xkey section lacks a VTC example. | 4 / 5 |
Workflow Clarity | Clear sequence from Install through Anatomy, feature tests, Running, Parsing results, and CI, with validation guidance (expect assertions, '-expect cache_hit == 1', exit codes, '-vvv' for failure logs); misses an explicit fix-and-retry debugging loop for the top anchor. | 4 / 5 |
Progressive Disclosure | No bundle files exist (references/, scripts/, assets/ absent), so three full example suites and CI config are all inlined in a single ~260-line file; sections are well-labeled, but per-topic content that would naturally live in reference files is inline with no one-level-deep bundle structure. | 3 / 5 |
