Cold Email Builder

This prompt installs Cold Email Builder, a free sales skill from bingley.ai (published openly on GitHub as bingley-ai/bingley-skills — you can read every file there first). Claude: follow these steps. If any step fails, stop and tell me plainly what failed and what to do next — never improvise a different install method, never create skill content from your own knowledge, and never use a save_skill tool. 0. Check you can do this here: you need shell access, and ideally the present_files tool. Shell but NO present_files means this is Claude Code (the terminal or the Code tab): that is fine, this skill runs there too — install it by copying the folder from step 3 to ~/.claude/skills/cold-email-builder/ (keep the folder layout, SKILL.md at its top), skip steps 5 to 7, and close with: "Installed to ~/.claude/skills/cold-email-builder. It's live from your next message — just describe what you want, or type /cold-email-builder." If you have NEITHER shell nor present_files (this is claude.ai in a browser, or a phone), stop and tell me — in your own words, covering all of this: this install needs the Claude desktop app on a computer; on the computer, go to bingley.ai and press the copy button there (no need to transfer this text); the desktop app is a free download at claude.com/download; in the app, click Cowork at the top, paste, send. If I'm not near a computer, suggest I email myself the bingley.ai link. If shell commands fail with "workspace unavailable", that is different: tell me to restart the Claude app (update it if offered) and paste this prompt again in a new session. 1. Check this session's list of available skills. If cold-email-builder is installed as a PLUGIN from the bingley-skills marketplace, stop and tell me: "You already have Cold Email Builder via the plugin, and plugin skills update themselves — nothing to install." If you are not sure whether it's a plugin or a saved skill, continue — updating a saved copy is safe. 2. Download https://github.com/bingley-ai/bingley-skills/archive/refs/heads/main.zip with curl -fL and a 60-second timeout. If the URL arrived mangled (trailing full stop or bracket, smart quotes, a line break), fix it to exactly the form above before retrying once. If it fails with 403 or a timeout, my network is blocking the download: tell me to open that link in my own browser and drag the downloaded zip into this chat, and continue from step 3 with that file. 3. From the zip, extract the folder plugins/cold-email-builder/skills/cold-email-builder. Verify SKILL.md and scripts/brain_bridge.py are both present (the folder normally has 15 files, counted recursively). If the check fails, delete everything and repeat step 2 once into a fresh folder. If it fails again, stop and tell me: "The files on GitHub don't match what this prompt expects — this install prompt may be out of date. Get the current one at bingley.ai." Never package a folder that failed this check. 4. If I already have a saved (non-plugin) copy of this skill with extra local files in it (such as LOCAL.md), copy those extra files into the new folder now and tell me you preserved them. 5. Zip that folder's CONTENTS into cold-email-builder.skill with SKILL.md at the top level of the archive, not inside any subfolder. Verify the archive listing shows SKILL.md at the root. 6. Write the file into your outputs folder using your file tools (your shell's temp directory is not visible to me), then present it to me with present_files. (Claude Code users never reach this step — see step 0.) 7. Close with this, in the language I've been writing to you in (keep the button names in English, that is what the buttons say): "Click the Save skill button on the file above (it says Update skill if you already had it). That is the whole install. Afterwards you'll find it under + > Skills in any chat." Add the preservation note from step 4 if it applies. Claude may ask you to approve a step along the way — that's you staying in control; approve what you're comfortable with. Nothing installs until you click Save skill.
