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, executable reference with tight code examples and genuinely useful error-recovery guidance. The main structural weakness is that everything — including a large API reference — lives in one 265-line file with no progressive disclosure to separate detailed material.
Suggestions
Move the API Reference class/method tables (Stitch, Project, DesignSystem, Screen, StitchToolClient) into a references/api.md file and keep only a one-line pointer plus a couple of key examples inline.
Deduplicate the repeated `import { stitch }` stanzas and the overlapping getHtml/getImage examples between Quick Start, Uploading, and Retrieving sections.
Reconcile the upload format lists: the Uploading section says only PNG/JPG/JPEG/WEBP are supported while the Project class table adds `.html`.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is code-dominant with almost no conceptual padding, but there is minor redundancy: the `import { stitch }` stanza repeats across three examples, the Quick Start overlaps the Generating/Retrieving sections, and env-var configuration appears in both the top section and the Explicit Configuration table. | 4 / 5 |
Actionability | Every section contains fully executable, copy-paste-ready TypeScript covering install, auth, generation, editing, variants, uploads, asset retrieval, the tool client, and error handling, with concrete edge behavior documented (e.g. 'never a silent empty string' for missing artifacts). | 5 / 5 |
Workflow Clarity | The Quick Start sequences create → generate → retrieve, and error handling provides an explicit feedback loop (check `e.recoverable`, and for `CLARIFICATION_REQUIRED` read `e.clarification` and call the same method again). It falls short of a 5 because there is no explicit end-to-end multi-step workflow with validation checkpoints. | 4 / 5 |
Progressive Disclosure | The single file is well-structured with clear section headers, but ~75 lines of API reference tables are inlined in SKILL.md with no bundle files at all — content that clearly belongs in a separate references/ file per the rubric's anchor 3. | 3 / 5 |
