Quality

Content

76%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is concrete, executable, and well-structured, with copy-paste JSON for every action. Its chief gap is the absence of validation/verification guidance for destructive actions like delete and edit, which the rubric explicitly penalizes.

Suggestions

Add a brief validation step for destructive actions, e.g. confirm the channelId/messageId before deleteMessage and verify the edit took effect, to lift workflow clarity above the destructive-ops cap of 3.

Reduce repetition by presenting one reusable JSON template for channelId/messageId actions and listing only the differing fields per action, tightening conciseness.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence (no Slack primer, no padding), but the repeated full JSON blocks for near-identical action shapes (edit/delete/read/pin/unpin all sharing channelId/messageId) could be tightened into a shared template plus variations.

4 / 5

Actionability

Every action ships as a complete, copy-paste-ready JSON payload with realistic IDs and values, covering the common cases concretely rather than with pseudocode or abstraction.

5 / 5

Workflow Clarity

Individual actions are unambiguous, but the skill includes destructive operations (deleteMessage, editMessage) with no validation or verification checkpoints (e.g., confirm before delete, verify the target message exists), which caps workflow clarity at 3 per the rubric.

3 / 5

Progressive Disclosure

No bundle files exist and none are needed for this self-contained single-tool skill; the body is well-organized into clear sections (Overview, Inputs, Actions, Ideas) with easy navigation, though it leans longer than the 'under 50 lines' simple-skill sweet spot.

Description

78%Weight 40%Scale 1-5

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 strong: third-person, concise, with an explicit 'Use when...' trigger and concrete Slack-specific actions. Its main weakness is that the action coverage in the description understates what the skill body actually supports.

Suggestions

Expand the description's action list to mention sending/editing/deleting messages and fetching member info, so it matches the skill's full scope and improves specificity and trigger-term coverage.

Make the 'when' clause more concrete by adding trigger phrases like 'when the user wants to send or edit Slack messages, pin decisions, or look up Slack members'.

DimensionReasoningScore

Specificity

Names the Slack-control domain plus concrete actions ("reacting to messages", "pinning/unpinning items"), but omits several actions the skill actually supports (send/edit/delete messages, member info, emoji list), so coverage has minor gaps rather than being comprehensive.

4 / 5

Completeness

It answers both what (react, pin/unpin) and when ("Use when you need to control Slack..."), but the 'when' clause is somewhat generic and lacks the multiple concrete trigger phrases that would push it to a 5.

4 / 5

Trigger Term Quality

Natural phrases a user would say are present ("react to messages", "pin/unpin", "Slack channels or DMs"), but common terms for the messaging actions (send, edit, delete messages) are missing, leaving a few natural synonyms uncovered.

4 / 5

Distinctiveness Conflict Risk

It targets a clearly distinct niche (controlling Slack via the slack tool) with little overlap risk against other skills, matching the 'clear niche with minimal conflict risk' anchor.
