What it does
Hlool Mail API is an agent skill from hloolx/HloolMail. Use HLOOL Mail public APIs to create temporary mailboxes, guide private-domain setup, read inbound emails, extract verification codes, and mark messages as read. Use when a user asks an AI agent to receive email, use HLOOL Mail, bind a custom domain for API-based receiving, poll a temporary inbox, or integrate verification-code workflows with HLOOL Mail.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `agents/openai.yaml` and `references/api-reference.md`).
It sits in Productivity & Automation, covering Email management. The repository describes itself as: Self-hosted temporary mail and custom-domain inbox platform.
When your agent uses it
- A user asks an AI agent to receive email
- Bind a custom domain for API-based receiving
- Poll a temporary inbox
- Integrate verification-code workflows with HLOOL Mail
Example prompts
- “/hlool-mail-api”
Requirements
- A credential in YOUR_KEY
Workflow steps
11 steps, taken from the first numbered list in SKILL.md.
- If the user has not already supplied an exact mailbox or domain, call GET /api/domains/available with X-API-Key before creating mailboxes.
- Treat data.public_domains and data.private_domains as the source of truth for selectable domains. Use legacy data.domains only as a…
- Present public and private domains as grouped choices. If the user wants multiple mailboxes or wants to process several domains, support…
- Do not ask the user to manually type a private domain when data.private_domains already contains API-key-accessible private domains.
- For a private domain that is not listed, guide the user to add it in the web console and point DNS MX to the platform MX target. Domain…
- Generate a mailbox with POST /api/generate-email, passing the selected domain unless the user explicitly wants a random root-domain…
- Ask the target service to send mail to that mailbox.
- Poll GET /api/emails/next?email=... every 3 seconds until a new unread message appears.
- If the response has has_email=false, wait and poll again. Stop after about 120 seconds and report a timeout.
- If the response has has_email=true, extract verification codes from message.subject, message.text_content, or message.html_content.
- Do not call a separate mark-read endpoint after /api/emails/next; it marks the returned message read automatically.
What it can do on your machine
Read from SKILL.md and the folder at commit b4e2135. 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 (its code samples are http).
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
Hlool Mail API loads about 1.6k tokens when it runs, and up to ~4k if it reads all its reference files. Until then it costs about 93 tokens; SKILL.md has 815 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 815 words (~1,594 tokens).
“Use only the documented public API. Do not reverse engineer the website, scrape the web console, guess hidden endpoints, or use undocumented authentication methods.”
