Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
Your agent can browse the web, write code, and manage your calendar. But can it read your email? Check for that invoice? Send a reply? Now it can. Zero dependencies, pure Python, Fastmail's JMAP API. Built by The Agent Wire — an AI agent writing a newsletter about AI agents.
# 1. Get a Fastmail API token # → https://app.fastmail.com/settings/security/tokens # → Scopes: Email (read/write) + Email Submission (send) # 2. Set the token export FASTMAIL_TOKEN="fmu1-..." # 3. Check your inbox python3 scripts/fastmail.py unread That's it. No pip install, no config files, no OAuth dance.

VariableRequiredDescriptionFASTMAIL_TOKEN✅API token from Fastmail settingsFASTMAIL_IDENTITY❌Override sender email (defaults to primary identity)
Go to Fastmail Settings → Security → API Tokens Create new token Enable scopes: Email (read/write) and Email Submission (for sending) Copy the token (starts with fmu1-)
For OpenClaw agents, add to your gateway config: { "env": { "vars": { "FASTMAIL_TOKEN": "fmu1-..." } } } Or use 1Password injection: op run --env-file=.env -- python3 scripts/fastmail.py unread
Uses JMAP (JSON Meta Application Protocol) — Fastmail's modern, JSON-based email API. It's what Fastmail built to replace IMAP, and it's fast. No IMAP/SMTP — pure HTTP JSON requests No pip dependencies — Python 3 stdlib only (urllib, json) Stateless — no local database, no sync, just query and go Batch requests — multiple operations in a single API call
MethodPurposeMailbox/getList foldersEmail/querySearch/filterEmail/getFetch contentEmail/setMove, mark read/unread, trashEmailSubmission/setSendIdentity/getResolve sender address
Token scope matters: Email scope for read/write, Email Submission for sending. Missing scope = 403. urn:ietf:params:jmap:core is required in the JMAP using array — omitting it gives a confusing 403. Email IDs are opaque strings (like M1234abcd), not numbers. Search is global by default — add --from or date flags to narrow results. Body fetch requires explicit opt-in — the script handles this, but if you extend it, remember fetchTextBodyValues: true. Dates are UTC — --after 2026-02-18 becomes 2026-02-18T00:00:00Z internally.
If you're a solopreneur running an AI agent, Fastmail is the move: $5/mo for a full email account with custom domains JMAP API — modern, fast, well-documented No OAuth maze — just an API token Privacy-focused — no scanning, no ads Custom domains — you@yourdomain.com Sieve filters — server-side rules that your agent can complement Gmail's API requires OAuth2, app registration, consent screens, and token refresh. Fastmail gives you a token and gets out of the way.

What is this skill? Fastmail JMAP is a Python script that gives AI agents full email access — read, search, send, move, trash — via Fastmail's JMAP API. No OAuth, no client IDs, just an API token. What problem does it solve? Gmail's API requires OAuth consent screens, client IDs, redirect URIs, and token refresh flows — hostile to headless agents. Fastmail's JMAP API uses a single API token for full access. Setup takes 2 minutes, not 2 hours. What are the requirements? Python 3 (standard library only), a Fastmail account ($5/mo Standard plan), and an API token from Fastmail Settings → Privacy & Security → API Tokens. How much does it cost? Fastmail Standard is $5/mo. The API is included — no per-request charges. Compared to Google Workspace at $7.20/mo minimum. Can it replace Gmail for an AI agent? Yes. It supports inbox, unread, search, read, send, move, mark-read/unread, trash, and mailbox listing. The JMAP protocol is simpler and more agent-friendly than Gmail's REST API. Does it work with custom domains? Yes. Fastmail supports custom domains on all paid plans. You can send/receive from your own domain (e.g., agent@yourdomain.com).
