Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00055 | $0.01449 |
| Opus 5.5 | $0.00022 | $0.00580 |
| Sonnet 5.5 | $0.00011 | $0.00290 |
| Haiku 4.5 | $0.00006 | $0.00145 |
Grade A, and why
dotnet-stylelint scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stylelint for Stylesheets in .NET Repositories
Trigger On
- the repo has
stylelint.config.*,.stylelintrc*, or CSS and SCSS assets under frontend folders - the user asks for CSS linting, duplicate style cleanup, naming convention enforcement, or design-system guardrails
- the repo needs a stylesheet gate beyond formatting alone
Do Not Use For
- JavaScript or TypeScript ownership; route that to
dotnet-eslintordotnet-biome - runtime accessibility, performance, SEO, or header checks; route that to
dotnet-webhint - repos that intentionally use only Biome for CSS linting and do not want a separate stylesheet linter
Inputs
- the nearest
AGENTS.md package.jsonstylelint.config.*or.stylelintrc*- the stylesheet file types in scope: CSS, SCSS, Less, embedded styles, or generated output
Workflow
- Confirm what Stylelint should own:
- plain CSS only
- CSS plus SCSS
- embedded styles in HTML, Markdown, or framework files
- Prefer repo-local installation and checked-in config.
- Start from a known shared config such as
stylelint-config-standard, then add syntax-specific packages only when the repo truly needs them. - Add repeatable scripts to
package.json, for example:stylelint "**/*.{css,scss}"stylelint "**/*.{css,scss}" --fix
- Keep ignore patterns explicit so build output, vendored assets, and generated CSS do not pollute the signal.
- Treat autofix as controlled cleanup:
- run on a bounded scope first
- inspect the diff
- rerun the frontend build if the repo compiles styles
- Use Stylelint for semantic CSS and selector policy, not as a replacement for site-level audits.
Bootstrap When Missing
- Detect current state:
rg --files -g 'package.json' -g 'stylelint.config.*' -g '.stylelintrc*'rg -n '"stylelint"|"stylelint-config-" --glob 'package.json' .
- Prefer a repo-local install:
npm install --save-dev stylelint stylelint-config-standard
- Add syntax packages only when the repo needs them for SCSS or embedded styles.
- Create or refine
stylelint.config.js,stylelint.config.mjs, or the existing config format. - Add repeatable commands to
AGENTS.mdandpackage.json, then verify with:npx stylelint "**/*.{css,scss}"npx stylelint "**/*.{css,scss}" --fix
- Return
status: configuredif Stylelint is now wired and repeatable, orstatus: improvedif the existing baseline was tightened. - Return
status: not_applicableonly when another documented tool already owns stylesheet linting and migration is not requested.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dotnet-stylelint is a skill published in the GitHub repository Postpartum-genushyacinthus29/dotnet-skills (13 stars, last pushed 14d ago), licensed MIT. It adds 55 tokens to every session and 1,449 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
