What it does
Accesslint Diff is an agent skill from sickn33/agentic-awesome-skills. 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.
Its SKILL.md is about 1.2k 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 Accessibility. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- Tasks that involve Accessibility
Example prompts
- “/accesslint-diff”
Requirements
- Node.js
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit ec02547. 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:
gitnpxnode
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git and npx, 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
Accesslint Diff loads about 1.2k tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 407 words of instructions outside code blocks.
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.

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 $ARGUMENTS: strip --branch <name> if present → branch mode. If --branch has no value, use the default branch above. Remainder is the URL.
When to Use
- Use this skill when the task matches this description: Diff a live page's accessibility violations against a baseline — by default compares uncommitted changes (stash-based), or pass --branch [
<name>] to diff against a branch. Reports only new violations introduced, violations fixed, and pre-existing count. Usescanfor a full audit with no diffing.
1. Audit
PORT=$(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 jsonBranch 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.
Keep the branch value in the quoted branch variable below; never paste or evaluate a branch name as shell syntax.
git diff --quiet && git diff --cached --quiet || git stash push -u -m "accesslint-diff-branch"
branch="<branch>"
git check-ref-format --branch "$branch" >/dev/null
case "$branch" in -*) echo "Refusing option-like branch name: $branch" >&2; exit 1 ;; esac
git rev-parse --verify --quiet "$branch^{commit}" >/dev/null
git switch "$branch"
npx -y @accesslint/cli@latest "<url>" --port "$PORT" --snapshot accesslint-diff --snapshot-dir /tmp --update-snapshot [--wait-for "<selector>"]
git switch - && git stash pop 2>/dev/null
npx -y @accesslint/cli@latest "<url>" --port "$PORT" --snapshot accesslint-diff --snapshot-dir /tmp --format json [--wait-for "<selector>"]Pass --selector, --include-aaa to both runs.

2. Report
Accessibility diff — http://localhost:3000/ vs main (94 rules, live DOM)
2 new · 1 fixed · 4 pre-existing hidden
New — Critical
- color-contrast — 2.1:1 (needs 4.5:1), #bbb on #fff
where: main > p.subtitle fix: darken to #767676
Fixed
- img-alt — <img src="old.jpg"> (no longer present)Each new violation: where (selector verbatim + file:line (symbol) if source present — never fabricate), evidence, fix (mechanical change or NEEDS HUMAN).
Don't edit. For fixes: apply mechanical ones then re-run accesslint:diff to verify; for bulk work hand off to accesslint:audit.
3. Tear down
npx -y @accesslint/chrome@latest stop --all # skip if ensure reported "managed":falseGotchas
ensurealways determines the port — never hardcode 9222.- CLI exit 2 = bad URL or page never loaded; check the dev server.
- Stash mode:
sleep 2covers most HMR cases; if baseline looks identical to current, add--wait-for "<selector>". - Branch mode: no HMR — CLI opens a fresh tab each run.
--wait-foris the rebuild gate. - Heavy DOM changes between runs cause selector drift — re-run with
accesslint:scanfor the full picture.
Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
