What it does

Diagnose Errors is an agent skill from Orange-OpenSource/Orange-Boosted-Bootstrap. Diagnostic workflow for build, lint, CI, and test errors in OUDS Web. Use this skill when encountering any error — Stylelint violations (border-radius, border:none, !default), ESLint failures (semicolons, console), Sass build errors (undefined variables, missing imports), CI job failures, JS test failures, or Pa11y accessibility violations. Provides a decision tree to identify the error category and step-by-step fix instructions.

Its SKILL.md is about 680 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 Frontend & Design, covering CSS and styling, Linting and formatting and Failing and flaky tests. It works with ESLint. The repository describes itself as: OUDS Web is an accessible, ergonomic and Orange branded framework based on Orange Unified Design System and Bootstrap. The licence is MIT.

When your agent uses it

Encountering any error — Stylelint violations (border-radius
ESLint failures (semicolons
Sass build errors (undefined variables
Missing imports)

Example prompts

“/diagnose-errors”

Requirements

Node.js

Workflow steps

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

Search variable in packages//scss/tokens/_component.scss and _semantic.scss
If absent → add to _composite.scss (only hand-editable file)
Verify import order: _raw → _semantic → _semantic-colors-custom-props → _composite → _component-colors-custom-props → _component

What it can do on your machine

Read from SKILL.md and the folder at commit f25f7be. 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

Diagnose Errors loads about 680 tokens when it runs. Until then it costs about 112 tokens; SKILL.md has 171 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~112
When it runs · the whole SKILL.md, loaded when a task matches: ~680

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.

Use this skill when encountering any error — Stylelint violations (border-radius, border:none, !default), ESLint failures (semicolons, console), Sass build errors (undefined variables, missing imports), CI job failures, JS test failures, or Pa11y accessibility violations.

Workflow: Diagnose Errors

Decision tree

Error signal	Category	Fix
`Unexpected property "border-radius"`	Stylelint	Use `@include border-radius()`
`Unexpected value "none" for "border"`	Stylelint	Use `border: 0`
`Expected variable to have default`	Stylelint	Add `!default`
`/* stylelint */` in CSS output	Comment leak	Use `//` not `/* */`
`Extra semicolon`	ESLint	Remove `;`
`Trailing comma`	ESLint	Remove trailing `,`
`Unexpected console statement`	ESLint	Remove from `js/src/`
`Can't find stylesheet to import`	Sass build	Run `npm install`, check `@ouds/web-common/scss/` path
`Undefined variable "$ouds-..."`	Token error	Check brand `_component.scss`/`_semantic.scss`, verify import order
`AssertionError`	JS test	Check changed ARIA attrs or class names
`Violation:` (URL + rule)	Pa11y	Missing role/aria-*, contrast, focus

Stylelint fixes

Forbidden properties → use mixins

scss

// ✗ → ✓
border-radius: 4px        → @include border-radius($ouds-border-radius-default)
transition: X             → @include transition(X)
border-top-left-radius: X → @include border-top-start-radius($val)

lighten()/darken() → use token variant

Stylelint comment leaking → use `//` comments

scss

// stylelint-disable property-disallowed-list
border-radius: 0;
// stylelint-enable property-disallowed-list

Token errors

Search variable in packages/<brand>/scss/tokens/_component.scss and _semantic.scss
If absent → add to _composite.scss (only hand-editable file)
Verify import order: _raw → _semantic → _semantic-colors-custom-props → _composite → _component-colors-custom-props → _component

ESLint fixes

Error	Fix
Extra semicolon	Remove `;`
Trailing comma	Remove `,`
Console statement	Remove from `js/src/`
String concatenation	Use template literal
Missing extension	Add `.js` to import

Validation

bash

npm run lint       # All rules pass
npm run dist       # Build succeeds
npm run js-test    # Tests pass

Stale cache

bash

rm -rf node_modules && npm install
npm run clean && npm run dist
