netlify-caching

Guide for controlling caching on Netlify's CDN. Use when configuring cache headers, setting up stale-while-revalidate, implementing on-demand cache purge, or understanding Netlify's CDN caching behavior. Covers Cache-Control, Netlify-CDN-Cache-Control, cache tags, durable cache, and framework-specific caching patterns.

Quality

Content

80%

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

A lean, highly actionable caching reference with executable code and no conceptual padding, scoring top marks on conciseness and actionability. It loses points on workflow clarity (no validation checkpoints, unverified purge) and progressive disclosure (a single inline file over 50 lines with no reference split).

Suggestions

Add an explicit verify step after cache purge, e.g. check that a subsequent request returns `Cache-Status: MISS` or confirm the `purgeCache` 202 response before declaring success.

Split the framework-specific patterns and/or the detailed Cache Tags / Cache Key Variation examples into a reference file (e.g. references/frameworks.md) and link to it from SKILL.md so the main file stays a tighter overview.

Present a short ordered workflow for the common cache-configuration task (set header → deploy → verify via Cache-Status) with an explicit checkpoint so the multi-step path is sequenced rather than implied.

DimensionReasoningScore

Conciseness

The body is a dense, reference-style guide that assumes HTTP/CDN knowledge — it never explains what a CDN or Cache-Control is — and uses compact tables and inline-annotated code where every token earns its place, matching the lean level-3 anchor.

3 / 3

Actionability

Provides fully executable, copy-paste-ready TypeScript using real `new Response` headers, `purgeCache` from `@netlify/functions`, and a concrete `netlify.toml` headers block, with specific directive values rather than pseudocode.

3 / 3

Workflow Clarity

Content is well-organized by topic but presents no explicit multi-step sequence with validation checkpoints, and the on-demand cache purge (a batch invalidation operation) is shown without a verify step, which caps this dimension at 2 per the batch-operation guideline.

2 / 3

Progressive Disclosure

Sections are clearly labeled and navigable, but everything lives inline in a single ~133-line file with no one-level-deep reference files to split out detail; at over 50 lines it does not meet the level-3 reference-split or simple-skill carve-out criteria.

Description

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.

A strong, third-person description that concisely states the skill's purpose and gives explicit, multi-trigger usage guidance scoped to a distinct Netlify niche. It avoids fluff and over-claims while enumerating concrete capabilities.

DimensionReasoningScore

Specificity

Names multiple concrete actions — "configuring cache headers", "setting up stale-while-revalidate", "implementing on-demand cache purge" — rather than vague language, matching the level-3 anchor of listing several specific concrete actions.

3 / 3

Completeness

Explicitly states what ("Guide for controlling caching on Netlify's CDN") and when ("Use when configuring cache headers, setting up stale-while-revalidate, implementing on-demand cache purge, or understanding Netlify's CDN caching behavior"), satisfying both halves with an explicit trigger clause.

3 / 3

Trigger Term Quality

Covers natural terms a Netlify user would actually say ("cache headers", "cache purge", "stale-while-revalidate", "CDN caching") alongside the platform-specific directives, giving good coverage of natural trigger language.

3 / 3

Distinctiveness Conflict Risk

The Netlify-CDN-specific niche and platform-scoped triggers (Netlify-CDN-Cache-Control, on-demand cache purge) make it clearly distinguishable and unlikely to fire for non-Netlify caching skills.
