Quality

Content

68%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 well-structured and actionable with lean tool sequences, named parameters, and specific pitfalls, but the batch-send workflow lacks explicit validation/verification steps, which caps workflow clarity at 3. Minor filler (the "When to Use" section) and the absence of concrete tool-call payload examples keep conciseness and actionability at 4.

Suggestions

Add an explicit verification step to the batch-send workflow (e.g., inspect the response for per-message successes/failures and confirm the batch count before declaring success) to lift workflow_clarity above the batch-operation cap.

Remove or replace the generic "When to Use" filler section with concrete trigger guidance.

Provide at least one concrete tool-call payload example (e.g., a sample POSTMARK_SEND_BATCH_WITH_TEMPLATES Messages array) to make guidance copy-paste ready.

DimensionReasoningScore

Conciseness

Mostly lean tool sequences, parameter lists, and pitfalls with little concept over-explanation, though the trailing "When to Use" section ("This skill is applicable to execute the workflow or actions described in the overview") is filler and a few directives are repeated across sections.

4 / 5

Actionability

Concrete tool slugs, explicit numbered tool sequences with Required/Optional tags, named parameters, and specific pitfalls give mostly executable guidance, though there are no copy-paste tool-call payload examples and the Template Variable Resolution pattern reads as pseudo-steps.

4 / 5

Workflow Clarity

Tool sequences are clearly ordered with some checkpoints (ACTIVE connection confirmation, validate-before-send), but the batch send workflow — a batch operation up to 500 messages — lacks explicit post-send verification/validation, capping workflow_clarity at 3 per the rubric.

3 / 5

Progressive Disclosure

No bundle files exist and the single-file body is well-organized with clear section headers and a Quick Reference table serving as navigation; minor gaps only, though no reference offloading is present (none is strictly needed).

Description

66%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 specific and well-scoped to a clear Postmark niche with good natural trigger terms, but it omits any explicit "Use when..." trigger clause, which caps completeness at 3. Third-person voice is correctly used throughout.

Suggestions

Add an explicit trigger clause, e.g., "Use when sending transactional emails via Postmark, managing templates, or monitoring delivery stats and bounces."

Include synonyms users might say such as "transactional email" or "spam complaints" to broaden natural keyword coverage.

Replace the catch-all "email delivery tasks" with the concrete actions already enumerated to tighten specificity.

DimensionReasoningScore

Specificity

Lists several concrete actions — "send templated emails, manage templates, monitor delivery stats and bounces" — naming the domain with multiple specific capabilities, though slightly less granular than the comprehensive 5-anchor example.

4 / 5

Completeness

Has a clear "what" via the listed actions, but lacks any explicit "Use when..." trigger clause; "Always search tools first for current schemas" is usage guidance, not trigger guidance, which caps completeness at 3 per the rubric.

3 / 5

Trigger Term Quality

Good natural keyword coverage ("Postmark", "templated emails", "templates", "delivery stats", "bounces") that users would actually say, but missing some synonyms like "transactional email" or "spam complaints".

4 / 5

Distinctiveness Conflict Risk

Tightly scoped to "Postmark" and "Rube MCP (Composio)" giving a clear niche with minimal conflict risk, but the generic "email delivery tasks" phrasing leaves minor overlap with broader email skills.
