Quality
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.
This description effectively communicates specific Slack-related capabilities with good distinctiveness. However, it lacks an explicit 'Use when...' clause that would help Claude know exactly when to select this skill, and could benefit from additional trigger term variations for better matching.
Suggestions
Add an explicit 'Use when...' clause, e.g., 'Use when the user asks about Slack messages, wants to check workspace activity, or needs to send/reply to Slack conversations.'
Include additional trigger term variations such as 'DM', 'direct message', 'Slack notifications', or 'workspace updates' to improve matching coverage.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'run the check-in workflow', 'surface new messages, active threads, and channel activity', 'send messages and replies'. These are clear, actionable capabilities. | 3 / 3 |
Completeness | Clearly answers 'what' (access Slack, run check-in workflow, send messages), but lacks an explicit 'Use when...' clause. The 'when' is only implied through the mention of 'daily note' context. | 2 / 3 |
Trigger Term Quality | Includes natural terms like 'Slack', 'messages', 'threads', 'channel', and 'replies' that users would say. However, missing common variations like 'DM', 'direct message', 'workspace notifications', or 'Slack updates'. | 2 / 3 |
Distinctiveness Conflict Risk | Clearly specific to Slack workspace integration with distinct triggers like 'Slack', 'check-in workflow', and 'daily note'. Unlikely to conflict with other communication or messaging skills. | 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 skill that efficiently guides Claude through Slack workspace management. It combines a clear multi-step workflow with concrete CLI commands, appropriate guardrails, and well-organized references. The content respects token budget while providing complete, actionable guidance.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is lean and efficient, assuming Claude's competence throughout. No unnecessary explanations of what Slack is or how CLIs work—every section delivers actionable information without padding. | 3 / 3 |
Actionability | Provides concrete, executable CLI commands with specific flags and examples. The bash code blocks are copy-paste ready, and the workflow steps specify exact commands to run. | 3 / 3 |
Workflow Clarity | The 8-step check-in workflow is clearly sequenced with explicit actions at each step. Includes implicit validation (error handling for not_in_channel, rate limits) and clear decision points (flag launches, don't auto-archive). | 3 / 3 |
Progressive Disclosure | Excellent structure with a concise overview and well-signaled one-level-deep references to CLI commands, channel priority, and discussion analysis. Content is appropriately split between the main skill and reference files. | 3 / 3 |
