61%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 well-organized, highly actionable reference for the Rube MCP Google Sheets toolkit: named tool sequences, precise parameters, and useful pitfalls. Its weaknesses are redundancy between per-workflow pitfalls and the 'Known Pitfalls' section, and missing validation/feedback loops around destructive and batch operations.
Suggestions
Remove the duplicated 'Known Pitfalls' section (or reduce it to a one-line pointer to per-workflow pitfalls) to cut repeated tokens.
Add an explicit validation step before destructive calls, e.g. read back the range with BATCH_GET before GOOGLESHEETS_DELETE_DIMENSION, forming a validate → act → verify loop.
Move the full parameter detail for less-common workflows (e.g., formatting, filters) into a references file to slim the main SKILL.md.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly dense and reference-style with tool slugs, params, and pitfalls, but the 'Known Pitfalls' section repeats seven items (tab names, range quoting, unbounded ranges, 2D arrays, colors, formatting IDs, rate limits) already covered per-workflow, which could be consolidated. | 3 / 5 |
Actionability | Concrete tool slugs, exact parameter names, A1 notation examples, and format specifics ('2D array', '0.0-1.0 floats', 'USER_ENTERED') give mostly executable guidance; minor gaps such as no example payloads keep it below fully copy-paste ready. | 4 / 5 |
Workflow Clarity | Sequences are explicit with tagged prerequisites and some verification hints ('use returned updatedRange to verify placement', 'verify formatting via readback'), but destructive operations like DELETE_DIMENSION get only 'double-check bounds' with no validate-then-act loop, and batch workflows lack systematic validation checkpoints. | 3 / 5 |
Progressive Disclosure | A single well-sectioned file with clear per-workflow organization, tagged roles, and a Quick Reference table for navigation; no nested references. The detailed tool reference bulk (~195 lines) could arguably live in a separate reference file, which keeps it below a 5. | 4 / 5 |
