Biome CLI v2.6.3

2.6.3

Patch Changes

• #12275 807e616 Thanks @​dyc3! - Added the new nursery rule noArraySortForMinMax, which reports sorting an array only to read its smallest or largest value. Use Math.min() or Math.max() instead.

  const minimum = array.toSorted((a, b) => a - b)[0];

• #12432 cf61682 Thanks @​dyc3! - Added the nursery rule noBooleanSortComparator, which reports sort comparators that return a boolean instead of a number. For example, array.sort((a, b) => a > b) never puts the first item before the second, so the array isn't sorted correctly.

• #12304 b4654c5 Thanks @​dyc3! - Added the new nursery rule noEagerArrayMethodsInLoops, which reports .map() and .filter() calls in the header of for...of loops. These calls build a new array that is only used by the loop.

  for (const name of users.map((user) => user.name)) {
    console.log(name);
  }

• #12121 66c3791 Thanks @​dyc3! - Added the nursery rule noNewRequire, which disallows calling require with new, such as new require("app-header").

• #12316 34b520d Thanks @​dyc3! - Added the new nursery rule noObsoleteAttributes, which disallows obsolete attributes on HTML elements and suggests what to use instead.

  <table bgcolor="#ffffff" cellpadding="5"></table>

• #12258 cce2385 Thanks @​dyc3! - Added the nursery rule noPathConcat, which disallows building file paths and URLs by joining strings to __dirname, __filename, import.meta.dirname, import.meta.filename, or import.meta.url.

  const fullPath = __dirname + "/foo.js"; // reported

• #12287 e12ad78 Thanks @​dyc3! - Added the new nursery rule noPlaywrightNthMethods, which disallows selecting Playwright elements by position with first(), last(), and nth(). A test that relies on the position of an element can act on a different element when the page changes.

  await page.locator("button").first().click();

• #12343 62ad123 Thanks @​vibbix! - Added the nursery rule noSelfNestedLayer, which disallows nesting a cascade layer inside a layer with the same name. Layer names inside an @layer block are relative to it, so the inner layer below creates the sublayer components.components instead of adding to components.

  @layer components {
    @layer components {
      .button {
        color: red;
      }

... (truncated)

Updates @modelcontextprotocol/client from 2.3.0 to 2.4.0

Release notes

Sourced from @​modelcontextprotocol/client's releases.

@​modelcontextprotocol/client@​2.4.0

Minor Changes

• #3085 a633756 Thanks @​claude! - Add an opt-in for sending scope on refresh-token requests, for authorization servers that reject a refresh without it (Microsoft Entra ID answers AADSTS90009 when the client and the resource are the same app registration, #2718). OAuthClientProvider gains an optional scopeForRefresh(tokens): auth(), and so the transports and withOAuth, sends the string it returns. refreshAuthorization() gains an optional scope. When a scope is sent and the response has none, the sent scope is kept on the returned tokens. Without either option the refresh request and the saved tokens are unchanged.

• #3047 46d9c99 Thanks @​KKonstantinov, @​tobi-oye, @​mattzcarey! - Add the Skills extension (SEP-2640), reachable through new ext/skills subpaths; package root exports are unchanged.

  • @modelcontextprotocol/server/ext/skills: SkillsExtension (attach(server) serves skills/list, skills/get, resources/directory/read and a skill://{+path} resource template), SkillsExtension.load(files) returning a SkillCatalog with entries and reload(), the SkillFiles storage adapter with memorySkillFiles, SkillSource for generated catalogs, skillEntry, and SkillCatalogError. Invalid skills are skipped with a warning (onWarning), or fail under strict. A file whose bytes are valid UTF-8 is served as text, whatever its MIME type; any other file as a base64 blob.
  • @modelcontextprotocol/server/ext/skills/node: loadSkills(folder) and nodeSkillFiles(folder).
  • @modelcontextprotocol/client/ext/skills: SkillsClient with list() (throws on an invalid entry; skipInvalid: true keeps the valid ones and returns the rest in invalid), get(), read(skill, path?) (size, digest and SKILL.md frontmatter verified, SkillVerificationError on a mismatch; a copy from the response cache that fails a check is fetched once more with cacheMode: 'refresh' first) and readDirectory().
  • @modelcontextprotocol/core/ext/skills: schemas, types and constants, including SKILL_LIMITS. The result schemas follow the stable spec, so ttlMs and cacheScope are required.

  SkillsExtension.attach is @experimental: how an extension is wired to a server may change in a minor release. The rest of the Skills API is stable.

  Works on 2025-11-25 and 2026-07-28. On 2026-07-28 only, the server sends the caching fields (ttlMs, cacheScope), and SkillsClient requires them and returns them from list(), get() and readDirectory().

Patch Changes

• #3083 ef38c67 Thanks @​claude! - The bundled Ajv validator is now built with fast-uri 3.1.8 (was 3.1.0). fast-uri 3.1.6 and later reject a $id or $ref whose text before the first colon is not a valid URI scheme (my_tool:output), or whose URN namespace is not valid (urn:my_tool:output): a schema that uses one no longer compiles, and a tool that carries it fails with an invalid-schema error. An underscore without a colon (my_tool_output) and a $ref into #/$defs/... or #/definitions/... are not affected.

• #2762 b022522 Thanks @​pcarleton! - x-mcp-header on a number-typed tool parameter is now rejected, matching the 2026-07-28 spec ("Parameters with type number are not permitted"; clients MUST exclude such tools from tools/list). Previously number was accepted only to satisfy an older conformance fixture that has since been corrected. integer, string and boolean are unaffected.
