78%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 highly actionable, token-efficient reference with executable examples throughout and useful error-avoidance guidance (key composition rule, Common Mistakes). Its main structural weakness is that the entire API surface lives inline in SKILL.md rather than being split across one-level-deep reference files.
Suggestions
Move the bulk API reference (Schema Quick Reference tables, sort key operations, execution options) into a references/ file (e.g. references/api.md) and keep only a quick-start entity definition plus pointers in SKILL.md, following the one-level-deep reference pattern.
Eliminate the duplicated primary/GSI index example between Entity Definition and Index Design — keep the full annotated example once and show only the LSI variation in the second.
Add an explicit validation loop for risky operations, e.g., "inspect with .params() and verify the composite keys before running .go() on updates/deletes", turning the existing .params() mention into a checkpoint step.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Dense tables and terse annotated code with near-zero prose padding, but two trimmable redundancies: the Installation section duplicates what Claude can derive, and the Index Design example re-shows the primary/GSI structure already demonstrated in the Entity Definition example (only the LSI is new). Fits the 4 anchor ("efficient; minor instances that could be trimmed") rather than 5. | 4 / 5 |
Actionability | Every section is copy-paste-ready executable TypeScript: full entity definition, all CRUD methods, chained and data() update expressions, query pagination with cursors, conditional writes, execution options, and a runnable scaffold script. Specific examples cover the common cases, matching the 5 anchor exactly. | 5 / 5 |
Workflow Clarity | Topic order gives an implicit sequence (define entity → design indexes → CRUD → queries), and checkpoints exist: ".params()" to inspect before executing and a Common Mistakes table covering error cases like update-on-missing-item. Falls short of 5 because there is no explicit validate-then-execute loop (e.g., run .params() to verify an expression before .go()) for the risky write/delete operations. | 4 / 5 |
Progressive Disclosure | Well-sectioned and the scripts/new-entity.sh reference is clearly signaled with a full description, but the ~270-line body inlines a complete API reference (attribute options, sort-key operation tables, execution options) that belongs in a references/ file — the rubric's 3-anchor example ("200 lines of API reference that could be in a separate file") is an exact match. Not a 4 because the bulk of reference content is not split out; not a 2 because structure and navigation are good and the one reference present is well signaled. | 3 / 5 |
