88%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, well-sequenced skill body: executable commands for every step, an explicit readiness check before MCP calls, and a numbered MCP workflow with validation checkpoints. Its weaknesses are redundancy — the Rules section and "When to Use" repeat content already stated elsewhere — and a length that sits just past what could be a leaner single file or a two-file split.
Suggestions
Merge the Rules section into the Step 2 Workflow: three of its four bullets (list-before-get, never invent props, call get-storybook-story-instructions first) already appear there verbatim, so a single authoritative rules list would cut ~6 lines of duplication.
Drop or shrink the "When to Use" section — its four bullets restate the frontmatter description's triggers without adding new information.
Make the backgrounding instruction concrete (e.g., specify running `npm start` via the shell tool's background option or with output redirected to a log file) so the start step is as copy-paste ready as the curl checks.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Efficient and entirely task-specific — no explanation of concepts Claude already knows — but the Rules section restates three Workflow steps verbatim ("Always call list-all-documentation before get-documentation", "Never invent props or variants", "always call get-storybook-story-instructions") and "When to Use" duplicates the frontmatter triggers. Not 3: the padding is duplication rather than unnecessary explanation; not 5: that repeated content could be trimmed. | 4 / 5 |
Actionability | Fully executable, copy-paste ready: the curl status check, "npm start", the poll-until-ready `until curl ... | grep -q "200\|301\|302"` loop, and "tool_search_tool_regex pattern: \"mcp_primer-storyb\"" are all directly runnable, and the workflow names exact tools and the ID pattern `components-<componentname>`. Covers the common cases (server already up, server not up, writing stories). | 5 / 5 |
Workflow Clarity | Clear two-phase sequence with explicit validation and a feedback loop: check status code (200/3xx → skip; 000 → start), start, then poll until ready before proceeding; the MCP workflow is a numbered 6-step list with checkpoints ("Never call get-documentation without first obtaining an ID from this list", "Verify props", call preview-stories after changes) and failure modes flagged ("they will fail silently"). | 5 / 5 |
Progressive Disclosure | No bundle files exist and the skill is self-contained with clear, well-organized sections (When to Use → Step 1 → Step 2 → Rules), so nothing is misplaced. Not 5: at ~85 lines it exceeds the under-50-line simple-skill bar, and the tool table / Rules content could arguably live in a reference file; not 3: structure and placement are otherwise appropriate with no buried or duplicated references. | 4 / 5 |
