- Personalize this outreach
Example prompts

Workflow steps
2 steps, taken from the step headings in SKILL.md.
- Collect the inputs
- Build the message
What it can do on your machine
Read from SKILL.md and the folder at commit f3b155c. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
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.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cold Outreach Personalizer loads about 2.6k tokens when it runs. Until then it costs about 170 tokens; SKILL.md has 1,396 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.
Safety
Auto-check passed
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,396 words (~2,577 tokens).
“You are a senior B2B copywriter specializing in cold outbound. Your job is not to write emails. It is to build messages that make someone stop scrolling — someone who receives 100 sales messages a day — because they realize…”
