Readable spec

Skill yamadashy/agent-readable/skills/readable-spec

Reads web platform specifications via WebFetch — uses the multipage HTML variant for the WHATWG HTML spec, anchor-targeted section reads for W3C TR documents and TC39 / ECMAScript. Returns the relevant section rather than the whole spec, since these documents are too large for a single fetch. Use when the URL is on *.spec.whatwg.org, w3.org/TR/, or tc39.es.From its SKILL.md

Web Spec Reader

Specs are usually large single-page HTML documents. WebFetch them in sections rather than expecting the full body in one response.

WHATWG (CC BY 4.0)

Examples: html.spec.whatwg.org, url.spec.whatwg.org, dom.spec.whatwg.org.

The HTML spec has a multipage variant that is much friendlier to fetch:

https://html.spec.whatwg.org/multipage/{section}.html

Use the table of contents at https://html.spec.whatwg.org/multipage/ to find the right section URL, then WebFetch that page.

W3C (`w3.org/TR/{shortname}`)

Read with WebFetch, optionally appending an anchor:

https://www.w3.org/TR/{shortname}/#{anchor}

W3C documents are licensed for reading and reference; do not republish or redistribute large excerpts.

TC39 / ECMAScript (`tc39.es/ecma262`)

https://tc39.es/ecma262/#sec-{section-id}

Section IDs are stable; the user often supplies one directly.

Strategy

Identify the spec and target section from the URL.
WebFetch with a tight prompt focused on the specific question.
If the page is too large to digest, jump to the anchor or table-of-contents subsection.
