Discovery
67%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
The description is concise and specific about what the skill does—adding attendees to Google Calendar events and sending notifications. Its main weakness is the absence of an explicit 'Use when...' clause, which limits Claude's ability to know when to select it. Adding trigger guidance and a few more natural keyword variations would strengthen it.
Suggestions
Add a 'Use when...' clause with trigger terms like 'invite people to a meeting', 'add participants to calendar event', 'send calendar invites'.
Include common keyword variations users might say, such as 'invite', 'participants', 'guest list', 'calendar invite', or 'meeting attendees'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description lists specific concrete actions: 'Add a list of attendees', 'existing Google Calendar event', and 'send notifications'. These are clear, actionable capabilities. | 3 / 3 |
Completeness | Clearly answers 'what does this do' (add attendees to a calendar event and send notifications), but lacks an explicit 'Use when...' clause or trigger guidance for when Claude should select this skill. | 2 / 3 |
Trigger Term Quality | Includes good natural terms like 'attendees', 'Google Calendar event', and 'notifications', but misses common variations users might say such as 'invite people', 'add participants', 'calendar invite', or 'guest list'. | 2 / 3 |
Distinctiveness Conflict Risk | Highly specific niche: adding attendees to Google Calendar events with notifications. This is unlikely to conflict with other skills due to the very targeted combination of Google Calendar + attendees + notifications. | 3 / 3 |

Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-crafted, concise skill that provides clear, executable commands for adding attendees to a Google Calendar event. It respects Claude's intelligence, includes a verification step, and is appropriately scoped for its single-purpose nature. The prerequisite reference to the gws-calendar skill is a good example of progressive disclosure without unnecessary nesting.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Very lean and efficient. The prerequisite note is necessary, and every line serves a purpose. No unnecessary explanations of what Google Calendar is or how APIs work. | 3 / 3 |
Actionability | Provides fully executable, copy-paste ready CLI commands with specific flags and JSON payloads. The example attendee emails make the pattern clear and easy to adapt. | 3 / 3 |
Workflow Clarity | Clear 3-step sequence: get event, patch with attendees, verify. The verification step serves as an explicit validation checkpoint. For this simple, non-destructive operation (adding attendees), this level of workflow clarity is sufficient. | 3 / 3 |
Progressive Disclosure | For a simple, single-purpose skill under 50 lines, the content is well-organized with a clear prerequisite callout and numbered steps. No need for external references or deeper structure. | 3 / 3 |
