Diff-Driven Smoke Tests
Skyvern-AI/skyvern
Reads your git diff, writes a handful of happy-path browser smoke tests, runs them with Skyvern or Chrome DevTools MCP and posts screenshot evidence to the PR.
Write content into Blot's production test blogs (gittest, dbtest, drivetest, icloudtest - one per sync client) the way a real user would, wait for Blot to sync and build it, then verify it end to…

Test Blogs is an agent skill from blotcms/blot. Write content into Blot's production test blogs (gittest, dbtest, drivetest, icloudtest - one per sync client) the way a real user would, wait for Blot to sync and build it, then verify it end to end - the published page, CDN and /assets responses, the generated assets on production disk, and their copy in S3 once the storage bucket exists - and clean up. Use when asked to write to, exercise or test the production test blogs, to check a sync client (Git, Dropbox, Google Drive, iCloud) after a change or deploy, to…
Its SKILL.md is about 2.3k 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 File uploads and storage, QA and bug reports and Document parsing. It works with Dropbox, Git, Google Drive and Amazon Web Services. The repository describes itself as: Turns a folder into a website. The licence is AGPL-3.0.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 6250431. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
gitsshawsdockercurlFrom the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
cdn.blot.imFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Test Blogs loads about 2.3k tokens when it runs. Until then it costs about 181 tokens; SKILL.md has 1,010 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.
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.

are fine without asking; say what you ran.Names must be unique and recognisable: prefix everything skilltest-{unix timestamp}
(e.g. skilltest-1760000000/post.md) so cleanup is a glob. Keep it small and
write only what the question needs:
Title: Skilltest {ts}
and Link: skilltest-{ts} metadata lines at the top so the post is at a
known URL, /skilltest-{ts}.): exercises _image_cache and _thumbnails
(thumbnails need the image in the post body or a Thumbnail: metadata line)..docx / .odt / .epub: exercises the converters and _assets.Use one blog for a quick check; all four when checking the sync clients or a deploy. Always note which blog(s) and file names you used for the log.
Dropbox, Drive, iCloud: mkdir -p a skilltest-{ts} folder in the blog's
folder above and copy the files in.
If a copy fails with "Operation not permitted", macOS privacy controls (TCC)
are blocking the shell from the cloud folder. Do not work around it. The
process macOS holds responsible is not Claude.app but the Claude Code binary
it bundles (a disclaimer helper starts it), at a versioned path; find it
with ps -o pid=,ppid=,comm= -p <pid> up the chain from $$, e.g.
~/Library/Application Support/Claude/claude-code/<version>/<hash>/claude.app.
Ask the operator to add that claude.app under System Settings → Privacy &
Security → Full Disk Access (⌘⇧G to paste the path) and restart Claude. The
grant follows the version, so it needs redoing after a Claude Code update.
Git: the remote URL, with credentials, is the single line of
~/.config/blot/test-blogs/gittest-remote (mode 600, outside every checkout so
any worktree's session finds it; the email in the URL is written %40). The
operator creates it once.
If the file is missing, tell the operator to create it; never ask for
credentials in chat. Never print, log or echo the URL.

Test Blogs is an agent skill from blotcms/blot. Write content into Blot's production test blogs (gittest, dbtest, drivetest, icloudtest - one per sync client) the way a real user would, wait for Blot to sync and build it, then verify it end to end - the published page, CDN and /assets responses, the generated assets on production disk, and their copy in S3 once the storage bucket exists - and clean up.
Test Blogs fits situations like: asked to write to; test the production test blogs; check a sync client (Git; ICloud) after a change.
Run `npx skills add blotcms/blot --skill test-blogs -a claude-code`. Or copy the skill folder (.claude/skills/test-blogs in blotcms/blot) into .claude/skills/test-blogs in your project. Claude Code loads it when a task matches its description.
Run `npx skills add blotcms/blot --skill test-blogs -a codex`. Or copy the skill folder (.claude/skills/test-blogs in blotcms/blot) into .agents/skills/test-blogs in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add blotcms/blot --skill test-blogs -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/test-blogs, .gemini/skills/test-blogs, .github/skills/test-blogs and .opencode/skills/test-blogs in your project.
Going by SKILL.md and its folder, Test Blogs needs the command-line tools its instructions call (git, ssh, aws, docker and curl). Our summary lists: Docker.
SKILL.md names 1 domain. In commands or code: cdn.blot.im; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Test Blogs is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.3k tokens (SKILL.md is roughly 9.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Test Blogs: Diff-Driven Smoke Tests (Skyvern-AI/skyvern, 23k stars), Latchkey (imbue-ai/latchkey, 130 stars), C Files (daxaur/openpaw, 173 stars) and OpenHarness End-to-End Evals (HKUDS/OpenHarness, 16k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
