Discovery
57%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 adequately identifies the WhatsApp/wacli domain and core actions but lacks explicit trigger guidance and comprehensive capability listing. The distinctiveness is strong due to the specific tool mention, but the missing 'Use when...' clause and limited trigger terms reduce its effectiveness for skill selection.
Suggestions
Add an explicit 'Use when...' clause specifying triggers like 'when user asks to send WhatsApp messages programmatically, automate WhatsApp, or access WhatsApp message history'
Expand trigger terms to include variations like 'WhatsApp automation', 'bulk messages', 'message logs', or 'WhatsApp API'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (WhatsApp) and lists some actions (send messages, search/sync history), but lacks comprehensive detail about specific capabilities like message formatting, attachment handling, or conversation management. | 2 / 3 |
Completeness | Describes what it does (send messages, search/sync history via wacli) but lacks an explicit 'Use when...' clause. The parenthetical '(not for normal user chats)' hints at when NOT to use it but doesn't clearly state when TO use it. | 2 / 3 |
Trigger Term Quality | Includes 'WhatsApp', 'messages', 'wacli', and 'history' which are relevant, but misses common variations users might say like 'text', 'chat', 'messaging app', or 'message history'. | 2 / 3 |
Distinctiveness Conflict Risk | Very specific niche with 'WhatsApp' and 'wacli CLI' as distinct identifiers. The clarification about not being for normal user chats further distinguishes it from general messaging skills. | 3 / 3 |
Total | 9 / 12 Passed |
Implementation
87%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, actionable CLI commands without unnecessary explanation. The safety section appropriately establishes guardrails. The only weakness is the workflow clarity around the confirmation step before sending, which is mentioned but not demonstrated with a concrete example or verification pattern.
Suggestions
Add a concrete example showing the confirmation workflow before sending (e.g., 'Before sending, confirm: Recipient: +14155551212, Message: "Hello!" - proceed? [y/n]')
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. No unnecessary explanations of what WhatsApp is or how CLIs work. Every line provides actionable information Claude needs. | 3 / 3 |
Actionability | Provides complete, copy-paste ready commands for every operation (auth, sync, search, send). Includes specific examples with realistic phone numbers and message text. | 3 / 3 |
Workflow Clarity | Commands are clearly organized by function, but lacks explicit validation/confirmation workflow. The 'confirm recipient + message before sending' instruction is mentioned but no concrete verification step is shown. | 2 / 3 |
Progressive Disclosure | For a simple CLI skill under 50 lines, the content is well-organized with clear section headers (Safety, Auth + sync, Find chats, Send, Notes). No need for external file references given the scope. | 3 / 3 |
