65%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.
The body delivers concrete, mostly-executable GAQL queries and quantified decision rules with tight, table-driven writing, but it is a monolithic 340-line file with no progressive disclosure and no validation checkpoints around its batch data pulls. One GAQL query uses an unsupported subquery construct and the promotional footer wastes tokens.
Suggestions
Add validation checkpoints to the audit workflow: verify row counts / handle pagination for large accounts, check for empty API results before computing distributions, and cross-check totals across the campaign, ad group, and keyword pulls.
Move the Reference Data tables (Quality Score impact, Ad Group Health Scorecard) and the full example audit report into a references/ file linked from SKILL.md, keeping the main file to the workflows and key thresholds.
Fix the invalid GAQL subquery in the 'no enabled ads' query (GAQL does not support NOT IN with a nested SELECT) — e.g., pull ad_group_ad joins and diff the ad group IDs client-side instead.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The core content (GAQL queries, threshold tables, severity rules) is dense with no re-explanation of concepts Claude already knows, but the trailing "About this skill" section (~10 lines of promotional Synter links with UTM parameters) is pure padding. This matches anchor 4 (efficient with minor trimmable instances) rather than 3, since the fluff is one contiguous off-topic block rather than scattered over-explanation. | 4 / 5 |
Actionability | Six ready-to-run GAQL queries plus quantified thresholds ("cannibalization_rate > 15%: SEVERITY = HIGH") and decision tables provide mostly executable guidance, matching anchor 4. It is not anchor 5 because one query ("Find ad groups with no enabled ads") uses `ad_group.id NOT IN (SELECT ...)`, which GAQL does not support since subqueries are invalid. | 4 / 5 |
Workflow Clarity | Workflow 1 has a clear Step 1-4 pull sequence and each analysis includes explicit severity classification logic, but checkpoints are missing or implicit: no validation of pulled data, no pagination/row-count handling for large accounts, and no empty-result or API-error feedback loops for the batch queries. This matches anchor 3 (sequence present, validation gaps) rather than 4, since the verification steps are entirely absent. | 3 / 5 |
Progressive Disclosure | No bundle files exist and all ~340 lines are monolithic in SKILL.md. Sections are well-organized with clear headers (Capabilities, Workflows 1-6, Reference Data, Examples), but reference data tables (Quality Score impact, Ad Group Health Scorecard) and the full mock audit report are inline content that belongs in separate reference files, matching anchor 3. It is not anchor 4 because nothing is split out and the file exceeds overview size. | 3 / 5 |
