Agent skills that finish the job.

Tested, plain-markdown skills for Claude Code, Codex, Cursor and any agent that reads a SKILL.md. Each one does a concrete job, like screening a resume, checking a site before launch or finding the page that should rank, and shows its evidence.

What do you need done?

Each workflow chains skills that hand work to each other. Pick the outcome; its page lists the skills in order with one block to install them all.

Start with these

Three skills, shown working.

Each one earned its place with a real run you can open. The rest are on the skills page, every one with its version, last update and known limits.

release

Web Preflight

Checks a site you own before you ship it, without pretending a status code is a finding. A 200 on /.env that matches the app shell is catch-all routing, a blanket 403 is an unanswered question, and a check that never ran becomes INCONCLUSIVE — never a pass.

Shown working, 24 Oct 2026, on skills.caffeinity.com. Probed 19 sensitive paths; nothing exposed and every security header in place: PASS. See the run

seo

SEO Crawl

Crawls a site you own and returns deterministic, evidence-backed technical SEO findings, with blocked or unrun checks reported INCONCLUSIVE rather than a pass.

Shown working, 24 Oct 2026, on skills.caffeinity.com. Found one broken internal link across 24 pages; the re-crawl after the fix came back clean. See the run

authoring

Tune Skill

Audits and fine-tunes a skill that already exists: the description that never fires, overlap with installed siblings, stale names and counts, handoff contracts that do not hand off. Ships check_skill.py, a deterministic validator over frontmatter, folder and heading agreement, description length and reference paths that do not exist. Not for creating one from scratch; that is draft-skill.

Shown working, 24 Oct 2026, on the 42 skills in this catalogue. Caught one skill that strict installers could not load; fixed in that skill and in tune-skill. See the run

Shown running · 23 and 24 October 2026

Tested on real targets, this site first.

Each tab is a real run: what the skill found, and what changed because of it. Nothing here is a mock-up; where a fix is still waiting on a decision, the tab says so.

seo-crawl · skills.caffeinity.com

One broken link, found by the crawler

pages      24 of 24 fetched
checks     5 complete
findings   1 error · 12 info

Cloudflare rewrote a sample address on the red-team page into a link that 404s. The address is now excluded from obfuscation and the 12 long titles and descriptions were shortened.

web-preflight · skills.caffeinity.com

Nothing exposed; headers in place

http → https     301
HSTS, CSP        present
X-Frame, nosniff present

All 19 high-value paths return a real 404 rather than the homepage, so a missing file cannot pass for a present one.

tune-skill · check_skill.py × 42 skills

tune-skill's own fallback parser had let the error through without PyYAML; it now fails it too.

tune-skill · regress.py × 44 skills

The family checked against itself

skills checked   44
regressions      0
improvements     23
new skills       3

regress.py runs the validator on every skill, then the checks one file cannot show: handoffs to skills that do not exist, and two skills claiming the same trigger. The nightly health job runs it; W10 fixes what it finds.

Install

Everything, in the agent you use.

One plugin carries every skill on this site plus eleven agents, one per workflow. Or take a single skill into any agent that reads a SKILL.md.

Claude Code

Every skill, plus the eleven agents: skill-builder, release-gatekeeper, seo-lead and the rest.

Codex

The same plugin from the Codex marketplace in the repo; then install caffeinity from the Plugins directory. caffeinity-routing picks the brew.

Any agent

Cursor, Qoder, Gemini CLI and others: one skill at a time with the skills installer. Swap wordsmith for any skill; every skill page has its exact command.

Agents can also read /llms.txt and the discovery index.

Need skills for your team's own work?

We build custom skills and workflows, tested on your real tasks, for the agents your team already uses.

Work with us

Open text you can read before you install.

Plain markdownA skill is a SKILL.md plus references and, sometimes, a script. Every card links to its source on GitHub.

One line to installEach card carries the exact command. npx skills add works with any agent that reads skills; mods install inside Claude Code.
