Quality

Discovery

100%

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 is a strong description that clearly identifies a specific niche (Postmark server-side email templates), lists concrete capabilities (Handlebars syntax, layout inheritance, template validation, cross-server pushing), and includes an explicit 'Use when' trigger clause. It uses proper third-person voice and is concise without being vague.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: creating, managing, sending, Handlebars syntax, layout inheritance, template validation, and cross-server pushing. These are distinct, concrete capabilities.

3 / 3

Completeness

Clearly answers both what (creating, managing, sending Postmark templates with Handlebars syntax, layout inheritance, validation, cross-server pushing) and when ('Use when creating, managing, or sending with Postmark server-side email templates'). The 'Use when...' clause is explicit.

3 / 3

Trigger Term Quality

Includes strong natural keywords users would say: 'Postmark', 'email templates', 'Handlebars', 'layout inheritance', 'template validation', 'cross-server pushing', and 'server-side'. These cover the domain well with terms users would naturally use.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive — 'Postmark' is a specific service, 'server-side email templates' with 'Handlebars syntax' and 'cross-server pushing' create a very clear niche that is unlikely to conflict with other skills.

Implementation

72%

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-structured skill with strong actionability and progressive disclosure. The main weaknesses are some redundancy between the body content and the Notes section, and the lack of explicit error recovery workflows for operations like template pushing and validation failures. Overall it serves as an effective reference for Postmark template operations.

Suggestions

Remove or significantly trim the 'Notes' section, as nearly all bullet points repeat information already presented in the body (template types, aliases, layout inheritance, validation).

Add an explicit feedback loop for template validation failures (e.g., 'If validation.AllContentIsValid is false, inspect validation.HtmlBody.ValidationErrors, fix issues, and re-validate').

DimensionReasoningScore

Conciseness

The skill is mostly efficient but has some redundancy. The 'Notes' section at the end repeats information already covered in the body (e.g., template types, aliases vs IDs, layout inheritance, validation). The overview table and quick start are lean, but the repeated content costs tokens without adding value.

2 / 3

Actionability

Provides fully executable JavaScript code examples for both sending with templates and validating templates. The Handlebars syntax examples are concrete and copy-paste ready. API endpoints are clearly listed with methods and descriptions.

3 / 3

Workflow Clarity

The Quick Start provides a clear 4-step sequence, and validation is mentioned. However, there's no explicit feedback loop for error recovery (e.g., what to do if validation fails), and the workflow for cross-server pushing (staging → production) is only mentioned but not sequenced with validation checkpoints.

2 / 3

Progressive Disclosure

Excellent progressive disclosure with a clear overview in the main file and well-signaled one-level-deep references to handlebars-syntax.md, layout-templates.md, and template-api.md. Content is appropriately split between the overview and detailed reference files.
