pp-nylas
Every Nylas API, plus a local SQLite mirror, cross-grant search, and confirm-by-hash sending no other Nylas tool has. Trigger phrases: `search my Nylas inbox across all grants`, `what changed in Nylas in the last 2 hours`, `first-response time on my Nylas threads`, `replay a Nylas webhook locally`, `preview a Nylas send before it goes out`, `use nylas`, `run nylas-pp-cli`.
Why this skill is useful
Adds a CLI tool with unique capabilities for querying and managing Nylas API data, including local SQLite mirroring and advanced search functionalities.

You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: nylas-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer): If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. When to Use This CLI Reach for nylas-pp-cli when you need to query Nylas data across multiple grants, run repeat 'what changed since' polls cheaply, compose SQL over messages and events, or sample the wire payload of a send before it goes out. For pure single-call API parity with the official SDK, the official nylas-cli is also a fine choice. Unique Capabilities These capabilities aren't available in any other tool for this API. Local state that compounds sync — Pull messages, events, threads, and contacts for one or all grants into a local SQLite mirror with per-(grant, resource) cursors so re-runs are incremental. Reach for this when an agent needs to answer questions repeatedly without burning rate-limit on every call. since — Query the local mirror for resources changed in the last N (e.g. 2h, 24h) across all grants in one shot. …
