What it does

Es X Eslint Support Update is an agent skill from eslint-community/eslint-plugin-es-x. Update eslint-plugin-es-x ESLint peer support in its own dedicated PR. Use during major release preparation or support policy changes to check the latest stable ESLint version and drop support for older ESLint major/minor lines by raising the minimum peer dependency without changing the Node.js engine range, updating peerDependencies, public documentation requirements, ESLint CI matrix entries, lockfile root metadata, release notes, and verification.

Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Linting and formatting. It works with ESLint, Node.js, npm and JavaScript. The repository describes itself as: ESLint plugin about ECMAScript syntactic features. The licence is MIT.

When your agent uses it

  • Tasks that involve Linting and formatting

Example prompts

  • “/es-x-eslint-support-update”

Requirements

  • Node.js

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Inspect current ESLint support declarations
  2. Check the latest stable ESLint version from npm before choosing the new support range
  3. Update package.json peerDependencies.eslint by raising the minimum supported ESLint version to the first patch release of the latest…
  4. Update CI
  5. Update user-facing support documentation
  6. Refresh lockfile root metadata with npm install --package-lock-only if package-lock.json does not update automatically.
  7. Add release notes through .agents/es-x-changeset/SKILL.md.
  8. Verify through .agents/es-x-release-verification/SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit b80ba91. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Es X Eslint Support Update loads about 798 tokens when it runs. Until then it costs about 120 tokens; SKILL.md has 353 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~120
When it runs · the whole SKILL.md, loaded when a task matches
~798

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

ES-X ESLint Support Update

Workflow

Use this when dropping old ESLint support. Keep this work separate from Node.js support drops and annual ECMAScript snapshot config updates unless the user explicitly asks for a combined PR.

  1. Inspect current ESLint support declarations:
    • package.json peerDependencies.eslint
    • docs/index.md Requirements ESLint line
    • .github/workflows/ci.yml ESLint matrix entries
    • top-level package-lock.json peerDependencies.eslint
  2. Check the latest stable ESLint version from npm before choosing the new support range:
    • Run npm view eslint version.
    • Treat the returned latest dist-tag version as the supported ESLint line.
    • Use both the major and minor numbers from that version when setting the minimum supported version.
    • Ignore prerelease or next dist-tags unless the user explicitly asks to support a prerelease.
  3. Update package.json peerDependencies.eslint by raising the minimum supported ESLint version to the first patch release of the latest stable major/minor line. For example, if npm view eslint version returns 10.3.2, use >=10.3.0. Do not add an upper bound unless the project already has one or the user explicitly asks for one.
  4. Update CI:
    • Remove jobs for every older ESLint major/minor line.
    • Keep one minimum-supported job for the latest stable ESLint major/minor line, such as 10.3.0 when the latest stable version is 10.3.x.
    • Keep platform coverage on a normal supported ESLint version.
    • Do not change Node.js engine support except where an ESLint job must run on an already supported Node.js version.
  5. Update user-facing support documentation:
    • Keep docs/index.md Requirements in sync with package.json peerDependencies.eslint.
    • Preserve the existing prose format: - ESLint `X.Y.Z` or newer..
    • Use the minimum version from peerDependencies.eslint rather than pasting the raw semver expression.
  6. Refresh lockfile root metadata with npm install --package-lock-only if package-lock.json does not update automatically.
  7. Add release notes through .agents/es-x-changeset/SKILL.md.
  8. Verify through .agents/es-x-release-verification/SKILL.md.

Current Major-Prep Pattern

For any major-prep ESLint support PR:

  • Check npm view eslint version.
  • Set the minimum supported ESLint version to the first patch release of the latest stable major/minor line, such as >=10.3.0.
  • Keep docs/index.md Requirements synchronized with the same minimum version while preserving its prose format.
  • Remove CI coverage for every older ESLint major/minor line.
  • Keep the Node.js support range unchanged in this PR.
