What it does

Add Plugin Rule is an agent skill from eslint-config/airbnb-extended. Fix the "<Plugin Updated with <rule" build error from script/checkUpdates.ts by adding a new or deprecated plugin rule to the right rules/ file. Use when pnpm build or pnpm config:build fails in the prebuild check, or after upgrading an ESLint plugin.

Its SKILL.md is about 650 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 and Agent instruction files. It works with ESLint, pnpm and TypeScript. The repository describes itself as: A powerful ESLint configuration extending the popular Airbnb style guide, with added support for TypeScript. The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit e855b33. 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:
- pnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- nextjs.org
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

Add Plugin Rule loads about 646 tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 251 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~68
When it runs · the whole SKILL.md, loaded when a task matches: ~646

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.

name: add-plugin-rule
description: Fix the "<Plugin> Updated with <rule>" build error from script/checkUpdates.ts by adding a new or deprecated plugin rule to the right rules/ file. Use when `pnpm build` or `pnpm config:build` fails in the prebuild check, or after upgrading an ESLint plugin.

Add a new plugin rule

packages/eslint-config-airbnb-extended/script/checkUpdates.ts runs before every build. It fails when a bundled plugin adds or removes a rule that our rules/ files don't list.

1. Find the rule

Run the check on its own:

bash

pnpm --filter eslint-config-airbnb-extended check:updates

The error names the plugin and rule, e.g. Next Plugin Updated with no-location-assign-relative-destination. It stops at the first plugin that fails, so run it again after each fix.

2. Learn what the rule does

Read the rule's docs and source in node_modules (e.g. meta.docs.description, meta.docs.url, meta.deprecated). Don't guess.

3. Pick the file

Look in script/checkUpdates.ts to see which rule objects are checked for that plugin. Then:

Rule state	Put it in
Active	The matching active set, e.g. `nextBaseRules` in `rules/next/nextBase.ts`
Deprecated by the plugin	The `deprecated*` set in the same file (e.g. `deprecatedReactBaseRules`), set to `'off'`
Experimental (stylistic)	The `experimental*` set, if the file has one

Only touch rules/ for the Extended config. Never change legacy/, which mirrors the original Airbnb configs one-to-one.

4. Add the rule

Match the existing style: one-line comment, docs link, then the rule. Keep the order of nearby rules.

// Prevent usage of <head> element.
// https://nextjs.org/docs/messages/no-head-element
'@next/next/no-head-element': 'warn',

Choosing the level:

Follow the plugin's own recommended config when it has one.
Use 'off' when the rule needs type info we don't enable, or clearly clashes with Airbnb style.
If unsure, use the plugin's recommended level and say so in the PR description. The maintainer decides.

5. Verify

bash

pnpm config:build
pnpm script:lint --filter=eslint-config-airbnb-extended

If a new rule changes behavior users will see, mention it in the PR and check whether docs/ needs an update.
