Freebies
Small, copy-paste tools I keep reaching for. No sign-up, no catch. Each one has a short writeup and a live demo.
agentblip
Turns your local Claude Code and Codex sessions into your Slack status, formatted on your own machine so the relay never sees your work. CLI, hosted relay, and a macOS menu bar app. MIT.
Plan-optimizer skill
Scores a plan against a rubric, critiques it, rewrites it, and keeps the best until the score plateaus. One-command install, the full SKILL.md to read, and a link to the deep-dive.
“Boil the ocean” agent prompt
Garry Tan's SOUL.md entry that makes your coding agent ship the complete thing, not a plan. Copy it into your system prompt / CLAUDE.md.
“Write like a human” prompt
A system prompt that strips the AI tells out of generated copy: conversational rhythm, real context, and a hard list of buzzwords to avoid.
Disposable email blocker
Reject throwaway inboxes at signup by checking the domain against a maintained list. Live checker + copy-paste server guard.
Cloudflare leaky-path blocker
Block scanner traffic (.env, .git, wp-login, phpMyAdmin) at Cloudflare's edge. Toggle groups and copy a ready WAF rule.
Input-anticipation skill
UIs that react to pointer intent before the click: a proximity focus ring, a magnetic target, and trajectory prefetch. Includes the perf budget and accessibility rules so it stays tasteful.
remark-mermaid-tldraw skill
Wire the remark-mermaid-tldraw package into any project so mermaid fences render as tldraw's hand-drawn SVGs at build time. Front-loads the install, the four wiring steps, and the MDX rehype-raw gotcha.
DevTools freeze bookmarklet
Freeze the page mid-hover to inspect tooltips, dropdowns, and other hover-only elements. Drag it to your bookmarks bar.
Cloudflare leaky-paths skill
The WAF rule as a downloadable Claude Code skill. Drop it in ~/.claude/skills/ and your agent can generate and apply it for any zone.
Plan-optimizer skill (.zip)
Prefer the file? The plan-optimizer skill as a plain download. Unzip into ~/.claude/skills/ and you're set.
Input-anticipation skill (.zip)
The anticipatory-UI patterns as a downloadable Claude Code skill. Drop it in ~/.claude/skills/ and your agent can add a proximity ring, magnetic target, or intent prefetch to a real app.
