What it does
Validate Stylebot is an agent skill from ankit/stylebot. Launch Stylebot in a real, headed Chrome window (via yarn dev:chrome) so the user can manually eyeball a change — in whatever checkout the current session is in, worktree or main. Use when the user wants to "try this out", "see it in the browser", "manually test/validate", "load the extension so I can look at it", or "smoke test this change" themselves, as opposed to running the automated e2e suite.
Its SKILL.md is about 780 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 Testing & QA, covering Git worktrees, End-to-end testing and QA and bug reports. The repository describes itself as: Change the appearance of the web instantly. The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit 96a61f5. 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:
yarn
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use yarn, 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
Validate Stylebot loads about 780 tokens when it runs. Until then it costs about 106 tokens; SKILL.md has 397 words of instructions outside code blocks.
Always· name and description, kept in context so the agent knows when to use it
~106

~780
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.

description
Launch Stylebot in a real, headed Chrome window (via `yarn dev:chrome`) so the user can manually eyeball a change — in whatever checkout the current session is in, worktree or main. Use when the user wants to "try this out", "see it in the browser", "manually test/validate", "load the extension so I can look at it", or "smoke test this change" themselves, as opposed to running the automated e2e suite.
Validate Stylebot manually
Stylebot's AGENTS.md defaults to Playwright e2e for verifying changes — use that
(yarn e2e) when the goal is confirming correctness. Reach for this skill instead
when the user wants to look at the extension with their own eyes: visual/UI tweaks,
"does this feel right" judgment calls, or anything the e2e suite doesn't cover.
What yarn dev:chrome already does
scripts/launch-chrome.mjs is worktree-aware out of the box — don't reinvent this:
Runs yarn watch and launches Chrome via CDP (Extensions.loadUnpacked) against
the current checkout's dist/.
Uses a Chrome profile at <checkout>/.chrome-dev-profile — scoped to whichever
worktree (or main) you run it from, so parallel sessions in different worktrees each
get their own isolated browser instance with no port/profile collisions.
Stamps a corner badge on every page with the checked-out branch name (e.g. 🌲 claude/fix-toggle-hitbox-1a2b3c; the checkout's folder name on a detached HEAD), so if the user has several of these windows open they can tell
them apart at a glance, including in the Cmd+Tab thumbnail.
Hot-reloads the extension in place on every rebuild — no need to relaunch after edits.
Opens to Hacker News as a default test page; the user can navigate wherever they want
to check the change.

How to run
Confirm you're at the repo root of the current session's checkout (worktree or
main — do not cd elsewhere; the whole point is testing what's checked out here).
If node_modules is missing, run yarn install first (fresh worktrees don't always
have it — check before assuming yarn dev:chrome will just work).
Launch it in the background — it blocks until the browser window closes:
yarn dev:chrome
Use run_in_background: true. Do not use yarn dev:chrome:headless here — headless
defeats the purpose of manual validation.
Watch the output for 🎉 Stylebot loaded on Hacker News to confirm it launched
rather than assuming success. If it fails to launch, the most likely cause is a
dev:chrome already running in this same checkout (the profile dir is locked) —
check for a stray background task before retrying.
Tell the user it's up, which worktree/badge to look for, and that edits will
hot-reload automatically. Let them drive from there — don't attempt to interact with
this window via browser automation tools, since the point is the human looking at it.
Stopping
The background task ends when the user closes the Chrome window. If they're done
before that, stop the background task directly rather than leaving it running.
