75%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, token-efficient reference body: an explicit 'When to apply' section, a clean one-level-deep index, and a quick-reference table of exact spellings and file paths. Recurring weakness is that the highest-value details live entirely in referenced files — including some that could not be verified — and there is no inline executable example or verification step.
Suggestions
Deduplicate the Index and Quick reference table: state each rule once (e.g., Title Case status codes and loop-prevention guards currently appear in both) and keep the Index as pure navigation links.
Add one short inline annotated-span snippet per language (or one TypeScript example) so the most common case — emitting an attribute and setting status — is executable without opening a referenced file.
Add a verification step for new attributes, e.g., 'before adding a new `maple.*` key, check `rules/mv-first-class-columns.md` and `packages/domain/src/tinybird/materializations.ts` to decide whether it needs an MV column', turning attribute introduction into a checkable sequence.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes competence — no OpenTelemetry primer, only repo-specific rules like 'Never `OK`, `ERROR`, `SUCCESS`, `FAILED`'. It sits at 4 rather than 5 because content is repeated between the Index descriptions and the Quick reference table (status codes, deployment env, service map, and loop prevention each appear twice), which could be trimmed. | 4 / 5 |
Actionability | Guidance is highly concrete — exact attribute spellings, exact file paths ('`apps/ingest/src/main.rs`: ... `init_tracing`', 'Read both via `DEPLOYMENT_ENV_SQL` / `deploymentEnvExpr`'), and canonical example files. It stops short of 5 because no inline executable snippet exists; the common cases rely on reading the canonical files and rule files rather than copy-paste-ready examples. | 4 / 5 |
Workflow Clarity | The 'When to apply' list clearly sequences when the skill applies, but this is a reference skill with no multi-step process. It fits the 4 anchor: usage is clear with minor gaps, notably no ordering guidance across the seven rule files and no verification checkpoint (e.g., how to confirm a new attribute is or isn't already MV-pre-extracted before adding it). | 4 / 5 |
Progressive Disclosure | The structure is exactly right — a concise overview, a one-level-deep Index with one-line summaries per `rules/*.md` file, a quick-reference table, and pointers to canonical repo files. It is scored 4 rather than 5 because the seven referenced `rules/*.md` files are not present in the skill bundle as provided (no `references/`, `scripts/`, `assets/`, or `rules/` directories exist), so the navigation layer cannot be verified end-to-end. | 4 / 5 |
