What it does

Hunter is an agent skill from refly-ai/refly-skills. Find emails with Hunter.io. Use when you need to: (1) discover professional email addresses, (2) verify email deliverability, or (3) find contacts at companies.

When your agent uses it

  • Discover professional email addresses
  • Verify email deliverability
  • Find contacts at companies

Example prompts

  • “/hunter”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Run the Skill and Get Run ID
  2. Open Workflow in Browser and Wait for Completion
  3. Extract Text Content

What it can do on your machine

Read from SKILL.md and the folder at commit 5a546d2. 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

    Shell commands in SKILL.md call:

    • jq

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • refly.ai

    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

Hunter loads about 456 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 81 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~456

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 81 words (~456 tokens).

“Find emails with Hunter.io. Use when you need to: (1) discover professional email addresses, (2) verify email deliverability, or (3) find contacts at companies.”
