Quality

Content

92%

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, well-structured skill that provides clear, actionable JSON payloads for every Slack action. It's concise, avoids unnecessary explanation, and organizes content logically with a summary table and individual examples. The only minor weakness is that the inline listing of all 11 actions makes the file somewhat long, though each example is compact.

DimensionReasoningScore

Conciseness

The content is lean and efficient. It doesn't explain what Slack is or how APIs work. Every section serves a purpose—inputs, action groups, and concrete JSON examples. The 'Ideas to try' section is minimal and arguably unnecessary but only adds two lines.

3 / 3

Actionability

Every action has a complete, copy-paste-ready JSON payload with realistic field values. The inputs section clearly specifies what needs to be collected and where to find values (e.g., message context lines). This is fully executable guidance.

3 / 3

Workflow Clarity

This is a single-tool, single-action skill—each action is independent and unambiguous. There are no multi-step destructive workflows requiring validation checkpoints. The action groups table and individual action examples make the available operations clear.

3 / 3

Progressive Disclosure

The content is well-organized with clear sections and a summary table, but all 11 action examples are inline. For a skill of this size, the JSON examples could be grouped more compactly or a reference file could hold the full catalog, keeping SKILL.md as a quick-start overview. However, with no bundle files, this is a reasonable single-file approach.

Description

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 has a clear 'Use when' clause and identifies specific actions (reacting, pinning/unpinning), which is good for completeness. However, the opening phrase 'control Slack from OpenClaw' is somewhat vague and the description could benefit from listing more concrete capabilities and natural trigger terms. The description uses second person ('you need to') which is not ideal per the rubric guidelines, though the penalty is specified only for specificity.

Suggestions

List more specific concrete actions beyond reacting and pinning, e.g., 'Adds emoji reactions to Slack messages, pins and unpins messages in channels and DMs' to improve specificity.

Add more natural trigger term variations users might say, such as 'emoji', 'react', 'pin message', 'unpin message', ':thumbsup:', to improve keyword coverage.

DimensionReasoningScore

Specificity

Names the domain (Slack) and some actions (reacting to messages, pinning/unpinning items), but doesn't comprehensively list all capabilities. It mentions 'control Slack' which is somewhat vague, though the specific examples help.

2 / 3

Completeness

Clearly answers both 'what' (control Slack via the slack tool, including reacting to messages and pinning/unpinning items) and 'when' (starts with 'Use when you need to...' with explicit trigger scenarios involving Slack channels or DMs).

3 / 3

Trigger Term Quality

Includes relevant keywords like 'Slack', 'reacting to messages', 'pinning', 'unpinning', 'channels', 'DMs', but misses common user variations like 'emoji reaction', 'add reaction', 'pin message', 'unpin message', or 'slack tool'.

2 / 3

Distinctiveness Conflict Risk

The mention of 'OpenClaw' and 'slack tool' adds some distinctiveness, but 'control Slack' is broad enough that it could overlap with other Slack-related skills (e.g., sending messages, managing channels). The specific actions of reacting and pinning help narrow it somewhat.
