accesslint-diff
Diff a live page's accessibility violations against a baseline — by default compares uncommitted changes (stash-based), or pass --branch [<name>] to diff against a branch. Reports only new violations introduced, violations fixed, and pre-existing count. Use `scan` for a full audit with no diffing.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
Default branch: !`git symbolic-ref refs/remotes/origin/HEAD --short 2>/dev/null | sed 's|.*/||' || echo main` Report only what changed. Locate; don't fix. If no URL in `$ARGUMENTS`, ask for one. Parse `$ARGUMENTS`: strip `--branch <name>` if present → branch mode. If `--branch` has no value, use the default branch above. Remainder is the URL. ## When to Use - Use this skill when the task matches this description: Diff a live page's accessibility violations against a baseline — by default compares uncommitted changes (stash-based), or pass --branch [<name>] to diff against a branch. Reports only new violations introduced, violations fixed, and pre-existing count. Use `scan` for a full audit with no diffing. ## 1. Audit ```bash PORT=$(npx -y @accesslint/chrome@latest ensure | node -e 'process.stdin.on("data",d=>process.stdout.write(""+JSON.parse(d).port))') ``` **Stash mode** (default — uncommitted changes). Tell the user first: _"Running in diff mode — stashing your changes to capture a baseline, then restoring. Your working tree will be fully restored."_ If `git stash push` fails, warn and exit. ```bash git stash push -u -m "accesslint-diff-baseline" npx -y @accesslint/cli@latest "

How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill accesslint-diff --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
