launch-emailWrite launch announcement emails and changelog digests for product releases.
Launch Email is an agent skill from amplitude/builder-skills. Write launch announcement emails and changelog digests for product releases. Use this skill whenever someone asks to write a launch email, draft an announcement email, create a product update email, write a changelog digest, or compose an email to accompany a product launch. Also trigger for "write the email for this launch," "draft the announcement email," "help me email our users about this," or any request to craft email copy tied to a product ship. Covers subject lines, announcement structure…
Its SKILL.md is about 2k 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 Development, covering Product launch strategy, Changelog and release notes and Email writing. The repository describes itself as: Open-source AI skills for product managers — battle-tested by PMs at Amplitude.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 51838c2. 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.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From 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.
Launch Email loads about 2k tokens when it runs. Until then it costs about 148 tokens; SKILL.md has 1,042 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.
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,042 words (~2,026 tokens).
“This skill helps write emails for product launches — from full-list announcements to segmented feature emails to changelog digests. Email consistently outperforms social for conversion because it reaches people who already care. The goal is to leverage that existing relationship…”

Run `npx skills add amplitude/builder-skills --skill launch-email -a claude-code`. Or copy the skill folder (launch-skills/skills/launch-email in amplitude/builder-skills) into .claude/skills/launch-email in your project. Claude Code loads it when a task matches its description.
Run `npx skills add amplitude/builder-skills --skill launch-email -a codex`. Or copy the skill folder (launch-skills/skills/launch-email in amplitude/builder-skills) into .agents/skills/launch-email 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 amplitude/builder-skills --skill launch-email -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/launch-email, .gemini/skills/launch-email, .github/skills/launch-email and .opencode/skills/launch-email in your project.
SKILL.md names no scripts, command-line tools or credentials: Launch Email is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. 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.
No licence was found for Launch Email or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
About 2k tokens (SKILL.md is roughly 8.1k 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 Launch Email: Momentum Planner (aaron-he-zhu/aaron-marketing-skills, 2.9k stars), Instructor Release (cognesy/instructor-php, 328 stars), Developer Docs Planning (hashgraph-online/awesome-codex-plugins, 1.2k stars) and Deliver Launch Checklist (product-on-purpose/pm-skills, 713 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
