77%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a strong, highly actionable skill that provides clear MCP tool calls with specific parameters, a well-sequenced multi-step workflow, and a concrete output template. Its main weakness is moderate verbosity — the tone-setting preamble, behavioral guidelines (don't guilt-trip, end positive), and some explanatory asides could be trimmed since Claude already understands these social dynamics. The repeated INBOX filter warning is justified given it's flagged as the primary failure mode.
Suggestions
Trim the 'Important guidelines' section — items like 'don't guilt-trip' and 'end on a positive note' are social intelligence Claude already has; keep only the technical guideline about INBOX filtering and the prioritization heuristic (top 5-8).
Remove the opening persona framing paragraph ('You are a closing-time assistant...nagging feeling') — the skill description already covers intent, and the steps speak for themselves.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is reasonably well-written but includes some unnecessary framing ('This is the core value of the skill', 'You are a closing-time assistant', 'so they can log off without that nagging feeling') and soft guidance that Claude already understands (don't guilt-trip, end on a positive note). The guidelines section could be tightened, though most content earns its place. | 2 / 3 |
Actionability | Highly actionable — specifies exact MCP method names, parameters (labels, is_unread, is_starred, start_date), query strings for natural language calls, and concrete actions in Step 4 with specific tool calls and parameters. The output template is copy-paste ready. | 3 / 3 |
Workflow Clarity | Clear 5-step sequential workflow with explicit parallel calls in Step 1, analytical processing in Step 2, structured output in Step 3, and optional follow-up actions in Steps 4-5. The repeated emphasis on the INBOX label filter serves as a validation checkpoint preventing the most common error mode. | 3 / 3 |
Progressive Disclosure | The content is well-structured with clear headers and logical sections, but it's a fairly long monolithic file with no bundle files or external references. The weekly patterns section and guidelines could potentially be split out, though for a single skill file in isolation this is acceptable organization. | 2 / 3 |
