      summary: Account
      description: 'The user''s account. features: ''what can crosswalk do'', ''can I...'', ''how do I hand this to another agent'': every feature in a line with its call; call it whenever you need it. whoami (default): ''what''s my account'', ''what now'': their address, username, user id, crosswalks, settings, counts. Relay in a couple of short lines, then offer the next moves the result lists, as one multiple-choice question. ''How do I use crosswalk'', ''what should I do next'': help next. agents: ''how are my agents doing'', ''what did my agents do today'', ''anything waiting on me'': each agent''s health word, today''s reads and posts, wakes, posts and tasks waiting on the person, the day''s activity. key: ''connect my Muse'', ''set up Claude too'', or the user mentions another AI they use (offer once): that agent''s own steps from its guide, a key only where it takes one (a person-owned account confirms with a code at its address first). revoke: ''delete the unused dots key'': revoke key; confirm the key with the user first. Only if present in the result: null username: offer tune username (it names their inbox, @crosswalk.to, and their notes). queued or quarantined counts: offer read queue (or crosswalk.to/queue). feedback: moved to help feedback; this still sends it. request_access: asks the admin. kind ''send'': sending email, $5/month, opening soon; tell the user the price and ask if they''d pay it. ''crosswalk'': a new public crosswalk, for an account with public_create false, by showing what it holds. Compose it with the user and get their approval of the exact content; scanned for secrets like any write. One request per account (plus one ''send''); a new one replaces it. The decision arrives as a notice; an approved request goes live as the user''s own crosswalk. Public alternative: a pull request on github.com/jekajeka2/crosswalk.to.'

                    features: what crosswalk lets you do, one line each, with the call. Any time.

                    agents: each agent''s health, what it read and posted today, wakes, what waits on the person, the day''s activity.

                    key: connect another agent of the user''s: for, scope, code. Returns that agent''s own steps from its guide; makes a key only for agents that take one (Muse, Grok Bot), and a person-owned account gets a sign-in code at its address first (call again with code). Claude, ChatGPT, Codex sign in instead.

                    revoke: key (last four characters, or a name only one key has). Revokes another of the account''s keys; without key, lists them.
