ping
Test tool — returns pong.
get_version
Returns the running version of @ourthinktank/founders-os, the rendering contract version (used to detect plugin/server drift), how the connector was launched (launchMethod: npx | global | local | unknown) with a tailored howToUpdate string, the release channel (channel: stable | prerelease), the published head of that channel, and the database schema status (dbSchemaStatus: current | behind | ahead | untracked | unknown) with a howToUpdateDb step when action is needed. Version comparison is semver-aware and channel-aware: stable builds compare against the `latest` tag, prerelease builds against the `next` tag, so a prerelease that is ahead of stable is NOT reported as an update. versionStatus is one of current | update-available | ahead | unknown; updateAvailable is true only when a genuinely newer version exists on your channel (with updateTo naming it). Call at session start; if updateAvailable is true relay current vs updateTo and the howToUpdate step, and if dbSchemaStatus is behind or untracked relay the howToUpdateDb step.
get_usage_guide
Returns a detailed guide on how to use Founders OS - covering all six domains (CRM, Tasks, Tags, Finance, Feeds, Memory), surface tools, search protocols, common workflows, and tips. Call this when uncertain about how to approach a task.
