cold-email-strategistA skill your agent uses when writing or fixing cold email — first-touch and follow-up sequences, re-engagement, subject lines, personalization at scale, ATL/BTL messaging, copywriting frameworks…
Cold Email Strategist is an agent skill from swan-gtm/gtm-skills. Use this skill when writing or fixing cold email — first-touch and follow-up sequences, re-engagement, subject lines, personalization at scale, ATL/BTL messaging, copywriting frameworks, deliverability, domain warmup, SPF/DKIM/DMARC, and email infrastructure. Triggers on 'cold email', 'email sequence', 'deliverability', 'warmup', 'bounce rate', 'inbox placement', 'email template', 'follow-up email', 'outbound email', 'subject line', 'personalization', 'email copy'.
Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 26 other files, including reference files (for example `references/atl-btl-messaging.md`, `references/atl-messaging.md` and `references/btl-messaging.md`).
It sits in Sales & Support, covering Cold outreach, Transactional email and Copywriting. The repository describes itself as: Open, production-grade GTM skills for AI agents. The licence is MIT.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 67abd04. 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.
Links to these hosts (documentation or services it may open):

Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Cold Email Strategist loads about 2.3k tokens when it runs, and up to ~36k if it reads all its reference files. Until then it costs about 123 tokens; SKILL.md has 893 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.
