Senior backend developer (.NET, AWS, custom MCP servers). On the side, I build open, plain-markdown skills that teach AI coding agents a craft: no API keys, nothing to run, nothing to pay for.
One line installs any of them. It detects your agent (Claude Code, Cursor, Codex, Qoder and others that read a SKILL.md) and puts the skill in the right folder.
| Skill | What it does | Install |
|---|---|---|
| do-better | Don't ask twice. Runs up to 100 sub-agents on the same task, then they attack, defend and judge each other in a bracket until one answer survives. | npx skills add arm-pz/do-better |
| recruiter-lens | Reviews resumes, CVs and LinkedIn profiles the way recruiters actually screen them. Never invents a metric. | npx skills add arm-pz/recruiter-lens |
| job-lens | Writes the better version from your resume and a job description: tailored resume, stronger bullets, keyword placement, summaries, LinkedIn rewrite, interview answers. Nothing invented. Pairs with recruiter-lens. | npx skills add arm-pz/job-lens --skill job-lens |
| wordsmith | Teaches your agent to edit, not just generate. 44 commands that keep the author's meaning and voice. | npx skills add arm-pz/wordsmith |
| deep-tutor | A patient teacher for any topic: curriculum, lessons, exams, ELI5. One question at a time. | npx skills add arm-pz/deep-tutor |
| keyword-guard | Plans topic clusters and kills keyword cannibalization so one page wins each query. | npx skills add arm-pz/keyword-guard |
| web-preflight | Checks a site you own before you ship it, without treating a status code as a finding. | npx skills add arm-pz/web-preflight |
| findable | Audits where your repo, skill or MCP server actually shows up in search, then drafts the About text, topics, README opening and a site page — plus dated re-checks. Nothing gets applied until you approve it. | npx skills add arm-pz/findable --skill findable |
Add --dry-run to any install to see what it will do first.
