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 highly actionable, well-structured workflow skill with executable code and a useful error-handling table. Its main gaps are mild redundancy across the export sections and the absence of an explicit validate-and-retry loop for batch generations.

Suggestions

Add an explicit validate-and-retry loop after batch generation (Step 2): inspect allSettled rejections, requeue failed clients, and only proceed once all succeed or failures are consciously accepted.

De-duplicate the PPTX layout-shift caveat and export-format guidance so each appears once — either inline in Step 3 or in the comparison table, not both.

Consider extracting the curl reference and/or export-format comparison into a separate reference file to shrink the SKILL.md body and strengthen progressive disclosure.

DimensionReasoningScore

Conciseness

Mostly efficient with brief Key Concepts and concrete code, but the PPTX-layout caveat and export-format guidance repeat across Step 3, Step 4, and the comparison table, and the ~230-line body could be tightened.

4 / 5

Actionability

Fully executable TypeScript and curl examples cover the common cases (template generation, batch, format selection, retrieval, sharing) and include a copy-paste-ready curl reference with a jq pipeline.

5 / 5

Workflow Clarity

Steps 1–6 are clearly sequenced, pollUntilDone verifies completion, and the batch step uses Promise.allSettled to capture per-item failures, but there is no explicit validate-then-retry feedback loop for failed generations.

4 / 5

Progressive Disclosure

Well-organized sections with clear headers and a one-level-deep Resources list linking to external Gamma docs, though most reference material is inlined in a single ~230-line file rather than split out.

Description

100%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 explicitly covers what the skill does, when to use it, and concrete trigger phrases, all scoped to a distinct Gamma API niche. The only weakness is cosmetic — the folded-scalar YAML formatting introduces stray blank lines and split phrases.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Generate from templates, retrieve exports, and manage sharing' plus PDF/PPTX/PNG exports and folder organization — giving comprehensive coverage of the Gamma API surface.

5 / 5

Completeness

Clearly states what ('Generate from templates, retrieve exports, and manage sharing via Gamma API') and when ('Use when creating content from template gammas, downloading PDF/PPTX/PNG exports, or configuring sharing and folder organization') with concrete trigger phrases.

5 / 5

Trigger Term Quality

An explicit Trigger clause covers natural phrases including synonyms and file extensions: 'gamma template', 'gamma export', 'gamma download PDF', 'gamma PPTX', 'gamma sharing', 'gamma from template'.

5 / 5

Distinctiveness Conflict Risk

The Gamma-specific niche and 'gamma'-prefixed trigger terms create a clear niche with minimal overlap risk against other skills.
