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 is a strong, highly actionable reference: concrete YAML examples throughout, explicit best practices, dialect-specific SQL, and hard rules stated as parse errors. Its main weaknesses are structural — the inline full JSON schema bloats token cost and duplicates prose, and the development workflow (create file, run rill start, validate) is never laid out as an explicit sequence. Moving the schema to a reference file and adding a short quick-start workflow would lift both conciseness and workflow clarity.
Suggestions
Move the full JSON schema (the '## Reference documentation' section) into a references/schema.md file and keep only a short summary inline, cutting ~40% of the skill's token footprint and eliminating duplication of format_preset, cache, and security descriptions.
Add an explicit quick-start workflow with validation checkpoints: create metrics/<name>.yaml with version: 1 and an explore: block, run rill start, fix any validation/parse errors, and confirm the dashboard renders.
Deduplicate content that appears in both prose and schema (format presets, cache configuration, security options) so each fact is stated once.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The instructional prose is lean and entirely Rill-specific (e.g., 'Do NOT set dimensions: or measures: in a derived metrics view', parse-error rules, dialect-specific functions), but the ~330-line inline JSON schema duplicates prose coverage (format_preset options, cache config, security) and could be tightened into a separate reference file. It sits above the 'noticeably verbose' anchor because the schema adds properties absent from prose (lookup_*, query_attributes, window), but below 'efficient' due to the duplication. | 3 / 5 |
Actionability | Every section provides copy-paste-ready YAML: a fully annotated complete metrics view ('metrics/orders.yaml' with dimensions, measures, and explore block), concrete security examples with templated user attributes, and dialect-specific executable SQL expressions (COUNT(*) FILTER (WHERE status = 'completed'), countIf(status = 'completed'), APPROX_COUNT_DISTINCT_DS_HLL(user_id)). This matches the 'fully executable, covers common cases' anchor. | 5 / 5 |
Workflow Clarity | The content is organized by topic rather than as a workflow: an implicit build order exists (table source, timeseries, dimensions, measures, explore, security) and parse-error rules are stated, but there is no explicit sequence with validation checkpoints (create the file in metrics/, run rill start, check for validation errors) — that crucial workflow step is buried only in the schema's top-level description. Checkpoints are missing or implicit, matching anchor 3. | 3 / 5 |
Progressive Disclosure | The body has good section headers, but no bundle files exist and the full JSON schema (roughly 330 lines of API reference) is inlined at the end under '## Reference documentation' when it clearly belongs in a separate references/ file. This matches 'content that should be separate is inline' with some structure present. | 3 / 5 |
