67%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 an actionable, well-structured operational guide with concrete MCP tool invocations, explicit connection-state validation, and sensible pitfalls. Its main weaknesses are mild redundancy (the search-first rule and tool block appear twice) and the absence of a result-verification loop after tool execution.
Suggestions
Merge the 'Tool Discovery' section into 'Core Workflow Step 1' — both contain a near-identical RUBE_SEARCH_TOOLS block, and the search-first rule is already stated in Prerequisites and Known Pitfalls.
Add a post-execution checkpoint after RUBE_MULTI_EXECUTE_TOOL, e.g. 'Inspect responses for errors or pagination tokens; on failure, re-run RUBE_SEARCH_TOOLS to confirm the schema before retrying.'
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly lean — code blocks and terse bullets, no tutorial padding — but it repeats itself: 'always call RUBE_SEARCH_TOOLS first' appears in Prerequisites, Tool Discovery, and Known Pitfalls, and the 'Tool Discovery' section and 'Core Workflow Step 1' contain two nearly identical RUBE_SEARCH_TOOLS blocks. This matches anchor 3 ('Mostly efficient but includes some unnecessary explanation or could be tightened'); it is not 4 because the duplication is real redundancy, not just minor trimming. | 3 / 5 |
Actionability | Concrete tool names with parameter structures are given for all four core tools (RUBE_SEARCH_TOOLS, RUBE_MANAGE_CONNECTIONS, RUBE_MULTI_EXECUTE_TOOL, RUBE_GET_TOOL_SCHEMAS), plus a Quick Reference table. Placeholders like 'TOOL_SLUG_FROM_SEARCH' are explicitly justified by the design decision to never hardcode slugs, which the guidelines permit. This is anchor 4 ('Mostly executable guidance... with minor gaps'); not 5 because no worked example with a real tool slug and arguments demonstrates an end-to-end call. | 4 / 5 |
Workflow Clarity | The three-step core workflow is clearly sequenced, with validation checkpoints present: confirm ACTIVE connection before running workflows, verify schema compliance, and check pagination tokens. It is anchor 4 ('Clear sequence with most checkpoints present; minor validation gaps') rather than 5 because there is no post-execution feedback loop — no step to inspect RUBE_MULTI_EXECUTE_TOOL responses for errors and retry/fix, which matters for a batch-execution tool. | 4 / 5 |
Progressive Disclosure | The skill is a single ~85-line file with well-organized, clearly headed sections and a Quick Reference table, and dynamic schema discovery justifies having no static reference files. It falls just short of the 'under 50 lines, well-organized sections' bar for a 5: the near-duplicate RUBE_SEARCH_TOOLS blocks in Tool Discovery and Core Workflow Step 1 are a minor organization gap that consolidation would remove. | 4 / 5 |
