| 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 WHEN you want to prove a UI change adds no new WCAG violations before a PR, or to separate a11y issues a diff introduced from pre-existing ones (use accesslint-scan for a full audit with no diffing). |

Report only what changed. Locate; don't fix. If no URL in $ARGUMENTS, ask for one.
Parse $ARGUMENTS: strip --branch <name> if present → branch mode. If --branch has no value, use the default branch above. Remainder is the URL.
When to Use
- Use this skill when the task matches this description: Diff a live page's accessibility violations against a baseline — by default compares uncommitted changes (stash-based), or pass --branch [] to diff against a branch. Reports only new violations introduced, violations fixed, and pre-existing count. Use
scan for a full audit with no diffing.
1. Audit
PORT=$(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.
git stash push -u -m "accesslint-diff-baseline"
npx -y @accesslint/cli@latest "<url>" --port "$PORT" --snapshot accesslint-diff --snapshot-dir /tmp --update-snapshot
git stash pop && sleep 2
npx -y @accesslint/cli@latest "<url>" --port "$PORT" --snapshot accesslint-diff --snapshot-dir /tmp --format json
Branch mode (--branch <name>). Tell the user first: "Diffing against <name> — checking out that branch to capture a baseline, then restoring. Your working tree will be fully restored."
Branch switching triggers a rebuild but not a browser reload — the CLI opens a fresh tab each time so it always reads the current build. Use --wait-for "<selector>" to gate the audit until the rebuild is ready; without it, warn the user that a slow build may yield a stale baseline.
git diff --quiet && git diff --cached --quiet || git stash push -u -m "accesslint-diff-branch"
git checkout <branch>
npx -y @accesslint/cli@latest --port --snapshot accesslint-diff --snapshot-dir /tmp --update-snapshot [--wait-for ]
git checkout - && git stash pop 2>/dev/null
npx -y @accesslint/cli@latest --port --snapshot accesslint-diff --snapshot-dir /tmp --format json [--wait-for ]
