Quality

Content

82%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.

A tight, highly actionable API skill with copy-paste examples and clear model/size decision guidance. Small gains available from deduplicating the table vs. the bullet lists and adding explicit failure-recovery steps.

Suggestions

Collapse the 'Choosing a model' and 'Choosing a size' bullet lists into the existing table (e.g. add a 'Pick when' column) to remove redundancy and save tokens.

Add a short failure-handling sequence for non-payment errors (e.g. retry on timeout, surface gateway validation errors) to strengthen workflow_clarity.

Consider moving the full model/price/size table to a references file and keeping only the default + edit-capable models inline, since the skill exceeds 50 lines.

DimensionReasoningScore

Conciseness

Mostly lean API reference with dense tables and JSON examples; the 'Choosing a model' and 'Choosing a size' bullet lists partially restate the table, and a few Notes lines could be trimmed, so it stops short of a 5.

4 / 5

Actionability

Fully executable POST endpoints with complete copy-paste JSON request/response payloads, concrete model aliases, sizes, and example interactions mapping user requests to specific calls.

5 / 5

Workflow Clarity

Single-call generate/edit actions are unambiguous with a payment-error checkpoint and gateway size validation noted, but there is no explicit validate-then-retry loop for failures, keeping it just below 5.

4 / 5

Progressive Disclosure

Well-organized into Generate/Edit/Examples/Notes sections with no nested references and self-contained content; at ~120 lines the model table is borderline-large for inline placement, so it is not a 5.

Description

87%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.

A strong, well-structured description that clearly states capability and trigger conditions in third person with rich natural synonyms. Minor room to add file-format keywords and broaden the distinct action set.

DimensionReasoningScore

Specificity

Lists several concrete actions ('generate, create, draw, make' and 'edit, modify, change, retouch') tied to the image domain, with only minor coverage gaps; not a 5 because the core actions reduce to two (generate/edit) rather than a comprehensive set of distinct operations.

4 / 5

Completeness

Explicitly answers both 'what' ('Generate or edit images via BlockRun's image API') and 'when' ('Trigger when the user asks to generate, create, draw, make an image — or to edit...') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Strong natural synonyms users would actually say ('draw', 'make an image', 'retouch'), but missing common file-format terms (.png/.jpg) that would push it to a 5.

4 / 5

Distinctiveness Conflict Risk

Scoped to 'BlockRun's image API' with distinct verb-based triggers, giving it a clear niche and minimal conflict risk with general-purpose skills.
