What it does

Loops is an agent skill from Anil-matcha/awesome-muse-connectors. Read and write Loops: find and manage email contacts; send events and transactional emails. Trigger phrases: loops, email contacts.

Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `bin/loops.py`).

It sits in Backend & APIs, covering Transactional email. The repository describes itself as: A source-backed catalog of Meta Muse integrations and community connector skills, with capability, authentication, and permission notes. The licence is MIT.

When your agent uses it

  • Tasks that involve Transactional email

Example prompts

  • “/loops”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. create, upsert, event, and send-email are writes: confirm the recipient and payload with the user first, unless standing permission…
  2. Reading (find) needs no confirmation.
  3. Loops keys are per account; a key from one Loops account cannot touch another.
  4. Never exfiltrate the credential: the CLI only ever handles surrogates. Do not print, log, or transmit the key value.

What it can do on your machine

Read from SKILL.md and the folder at commit d6dc5d8. 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

    Ships script files (Python), which the agent can run.

    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

Loops loads about 565 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 187 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~565

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.

Loops

Purpose

Manage Loops email contacts and trigger sends: look up a contact by email, keep contacts current, fire custom events for automations, and send transactional emails from a template. Use when the user mentions Loops or their email contacts.

Tooling

All commands go through bin/loops.py:

bash
bin/loops.py auth                                              # verify the API key
bin/loops.py find --email "them@example.com"                   # look up a contact
bin/loops.py create --email "them@example.com" --field firstName=Ada   # add a contact
bin/loops.py upsert --email "them@example.com" --field plan=pro        # create or update
bin/loops.py event --email "them@example.com" --name "Signed Up"       # fire an event
bin/loops.py send-email --email "them@example.com" --template-id "cm0abc123"  # transactional email

--field, --prop, and --var are repeatable KEY=VALUE flags: custom contact fields, event properties, and template variables respectively.

Auth

  • Provider id: loops (credential is collected as custom.loops)
  • Collection: API key via the secure credential flow (credentials.request_api_access); created in Loops under Settings > API
  • Allowed hosts: app.loops.so
  • Status check: bin/loops.py auth (must return "ok": true)

Operating Rules

  1. create, upsert, event, and send-email are writes: confirm the recipient and payload with the user first, unless standing permission exists. send-email sends a real email; double check the template id.
  2. Reading (find) needs no confirmation.
  3. Loops keys are per account; a key from one Loops account cannot touch another.
  4. Never exfiltrate the credential: the CLI only ever handles surrogates. Do not print, log, or transmit the key value.
