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

87%

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

An efficient, actionable reference on Netlify CDN caching with executable examples and strong organization. The main gap is the absence of an explicit validation checkpoint for the on-demand purge workflow, a cache-mutating operation where confirming success matters.

Suggestions

Add a verification step after purgeCache calls — e.g., re-request the URL and confirm the Cache-Status header shows a miss/fwd=miss — so the purge workflow has an explicit success checkpoint.

For the purge credential path, note how to confirm the purge succeeded (HTTP 202 acknowledgement vs. checking Cache-Status) to close the feedback loop for batch/programmatic invalidation.

Consider a short 'Verification' checklist under Cache Tags and On-Demand Purge mirroring the debugging guidance, so destructive cache invalidation follows a validate-then-proceed pattern.

DimensionReasoningScore

Conciseness

Lean reference that assumes competence — it never explains what a CDN or HTTP caching is, and every section delivers direct guidance with executable snippets. No filler or padded context.

3 / 3

Actionability

Provides fully executable TypeScript and TOML snippets with concrete header values and exact purgeCache calls, plus a comparison table of headers — copy-paste ready and specific.

3 / 3

Workflow Clarity

Sections are well sequenced (default behavior, headers, tags/purge, vary, frameworks, dev, debugging, constraints), but the cache-mutating purge workflow lacks an explicit verify/retry checkpoint confirming the purge took effect.

2 / 3

Progressive Disclosure

A self-contained single file with no bundle directories present and no dangling or nested references; content is organized into clearly labeled sections that act as a navigable overview of the topic.

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 names concrete capabilities, includes an explicit Use-when trigger, and is tightly scoped to Netlify CDN caching. No vague fluff or over-claims; every clause earns its place.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "configuring cache headers, setting up stale-while-revalidate, implementing on-demand cache purge" — matching the anchor for listing multiple specific concrete actions.

3 / 3

Completeness

Explicitly answers both what ("Guide for controlling caching on Netlify's CDN") and when ("Use when configuring cache headers...or understanding Netlify's CDN caching behavior") with an explicit Use-when clause.

3 / 3

Trigger Term Quality

Uses natural terms a user would say — "caching on Netlify", "cache headers", "stale-while-revalidate", "cache purge", "CDN caching" — with good coverage and no jargon-only language.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche — Netlify CDN caching — with distinct, vendor-specific triggers (Netlify-CDN-Cache-Control, cache tags, durable cache) unlikely to fire for unrelated skills.
