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 its capabilities, clearly identifying the domain (iMessage/SMS) and concrete actions (listing chats, viewing history, sending messages). Its main weaknesses are the lack of an explicit 'Use when...' trigger clause and missing common user phrasings like 'text message' or 'send a text'.
Suggestions
Add a 'Use when...' clause, e.g., 'Use when the user wants to send or read text messages, check iMessage conversations, or interact with Messages.app.'
Include natural trigger term variations like 'text message', 'texting', 'send a text', 'conversation history', 'message thread'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'listing chats', 'history', and 'sending messages'. Also specifies the tool ('Messages.app') and interface type ('CLI'). | 3 / 3 |
Completeness | Clearly answers 'what does this do' (listing chats, history, sending messages via CLI), but lacks an explicit 'Use when...' clause specifying when Claude should select this skill. | 2 / 3 |
Trigger Term Quality | Includes good terms like 'iMessage', 'SMS', 'chats', 'messages', and 'Messages.app', but misses common user variations like 'text message', 'texting', 'send a text', or 'conversation history'. | 2 / 3 |
Distinctiveness Conflict Risk | Very distinct niche — iMessage/SMS via Messages.app CLI is highly specific and unlikely to conflict with other skills. The combination of messaging platform and CLI interface creates a clear identity. | 3 / 3 |
Total | 10 / 12 Passed |
Implementation
85%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-structured CLI skill with excellent actionability—every command is concrete and executable. The workflow includes proper confirmation checkpoints before sending messages. The main weakness is mild verbosity in the 'When to Use' / 'When NOT to Use' sections, which could be trimmed since Claude can infer when to use a messaging CLI tool.
Suggestions
Trim the 'When to Use' and 'When NOT to Use' sections—Claude can infer most of these from context. A brief note about alternative channels (Telegram, Signal, etc.) would suffice instead of listing each one.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The 'When NOT to Use' section is somewhat verbose listing every alternative messaging platform, and the 'When to Use' section restates obvious triggers. However, the command examples themselves are lean and well-structured. | 2 / 3 |
Actionability | All commands are fully executable and copy-paste ready with concrete flags, arguments, and realistic examples. The example workflow shows a complete end-to-end process with actual CLI commands and jq piping. | 3 / 3 |
Workflow Clarity | The example workflow clearly sequences steps (find chat → confirm with user → send after confirmation), with an explicit confirmation checkpoint before the destructive action of sending a message. Safety rules reinforce validation requirements. | 3 / 3 |
Progressive Disclosure | For a CLI tool skill of this size (~80 lines), the content is well-organized into logical sections (commands, service options, safety, workflow) without needing external file references. Navigation is clear via headers. | 3 / 3 |
