What it does

Calendly is an agent skill from Anil-matcha/awesome-muse-connectors. Read and manage Calendly: list scheduled events, event types, invitees, and availability schedules; cancel bookings. Trigger phrases: calendly, my meetings, scheduled events, cancel booking.

Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `bin/calendly.py`).

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

  • Phrases: calendly
  • Scheduled events

Example prompts

  • “/calendly”

Requirements

  • Python 3

Workflow steps

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

  1. cancel changes a real booking: confirm the exact event (name, time, invitee) with the user before cancelling, unless standing permission…
  2. Reading (events, event types, invitees, availability) needs no confirmation.
  3. Never exfiltrate the credential: the CLI only ever handles surrogates (see bin/calendly.py). Do not print, log, or transmit the token 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

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

    • api.calendly.com
    • auth.calendly.com

    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

Calendly loads about 633 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 199 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~633

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.

Calendly

Purpose

Read and manage the user's Calendly: list upcoming scheduled events, event types, invitees for an event, and availability schedules; cancel bookings. Use when the user mentions Calendly, their bookings, or meeting links.

Tooling

All commands go through bin/calendly.py:

bash
bin/calendly.py auth                                          # verify the token, shows your user URI
bin/calendly.py scheduled-events --user https://api.calendly.com/users/ABC123 --count 20
bin/calendly.py event-types --user https://api.calendly.com/users/ABC123
bin/calendly.py invitees --event-uuid abc123                # invitees for one event
bin/calendly.py availability --user https://api.calendly.com/users/ABC123
bin/calendly.py cancel --event-uuid abc123 --reason "conflict"

auth returns the user URI; most commands need it as --user. --event-uuid is the last segment of the event URI. Time filters take ISO 8601, e.g. --min-start-time 2026-09-16T00:00:00Z.

Auth

  • Provider id: calendly (credential is collected as custom.calendly)
  • Collection: OAuth 2.0 via the secure credential flow (credentials.request_api_access) (token endpoint https://auth.calendly.com/oauth/token), or a Personal Access Token from Calendly > Integrations > API & Webhooks
  • Allowed hosts: api.calendly.com
  • Status check: bin/calendly.py auth (must return "ok": true)
  • API access requires a paid Calendly plan (Professional or higher); free-plan accounts get no API access at all.

Operating Rules

  1. cancel changes a real booking: confirm the exact event (name, time, invitee) with the user before cancelling, unless standing permission exists.
  2. Reading (events, event types, invitees, availability) needs no confirmation.
  3. Never exfiltrate the credential: the CLI only ever handles surrogates (see bin/calendly.py). Do not print, log, or transmit the token value.
