Tools (40)

• bardo_account_deletion_cancel
  Cancel a pending deletion, whichever phase it's in — gathering confirmations or already counting down. No step-up needed, and nothing else does this implicitly: logging in and reading your own notes …
• bardo_account_deletion_request
  Request permanent deletion of this identity — the account, its notes, everything. There is no undelete, unlike note deletion's grace period. Requires the original request plus two more confirmations,…
• bardo_account_deletion_status
  Check whether a deletion request is pending for this account, and where it stands: "none", "gathering" (still collecting confirmations), or "confirmed" (counting down to the actual, permanent purge).
• bardo_attestation_issue
  Assemble and sign a verifiable attestation — a self-contained, offline-verifiable claim about anything. The document itself is handed back, not stored anywhere (same as bardo_sign itself — there's no…
• bardo_contact_delete
  Remove the registered contact endpoint. Requires a step-up puzzle. If challenge_id and answer are omitted, a fresh puzzle is returned — solve it yourself, then call this tool again with both paramete…
• bardo_contact_get
  View the contact endpoint registered for out-of-band security alerts.
• bardo_contact_set
  Set or update the contact endpoint (email or webhook URL) for security alerts. Requires a step-up puzzle. If challenge_id and answer are omitted, a fresh puzzle is returned — solve it yourself, then …
• bardo_dashboard
  Get oriented in one call: note count vs. the soft/hard limits, unread notices, every tag you've used so far (check before inventing a new one), your pinned entry-point notes (read these first if you …
• bardo_decrypt
  Decrypt a sealed-box ciphertext addressed to you (root or service key).
• bardo_derive
  Derive (and register) a service-scoped identity, e.g. 'github.com'.
• bardo_document_revoke
  Revoke a document you issued. Proof is a fresh signature over 'revoke:' + the document's id, verified against the key its id already committed to, not an account lookup (Bardo never stored the docume…
• bardo_document_status
  Check whether a signed document is revoked. `id` is the document's own top-level `id` field (a ni:// URI) — the same thing credentialStatus.id (BardoRevocationCheck) points at. Safe to cache a "not r…
• bardo_encrypt
  Sealed-box encrypt a UTF-8 plaintext to a recipient's encryption public key.
• bardo_export
  Export the raw spirit key (subject to policy). Handle with care. Only needs a step-up puzzle if your policy's export_mode is require_repuzzle — checked automatically, so you don't need to know your o…
• bardo_feedback
  Send feedback straight to Bardo's operator — a suggestion, a complaint, or a security concern (kind: 'suggestion' | 'complaint' | 'security'). One-way and stateless: this call carries no memory of an…
• bardo_link_add
  Connect two notes with a reason, written from from_note_id's perspective ("clarifies my earlier assumption about X"). Set is_bidi=True only when the relation reads the same from either side (e.g. "re…
• bardo_link_delete
  Remove a link between two notes.
• bardo_login
  Begin authentication with your api_key. Returns a puzzle you must solve YOURSELF (that's the point — a script solving it would make the proof worthless), then call bardo_solve(challenge_id, answer).
• bardo_note_add
  Leave a note for your future, stateless self. title: a short name for the note, if it deserves a handle bigger than tags offer. summary: your own compressed reasoning for why it matters, for your fut…
• bardo_note_delete
  Delete a note (the whole thing, all versions together). Not immediate — it disappears from view right away but is only purged for real after a grace period, so bardo_note_undelete can still bring it …
• bardo_note_get
  Fetch one note's full text (always the current version — any id from this note's history still resolves here), plus a preview of its directly linked notes. Omit offset/length for the whole text in on…
• bardo_note_history
  See every surviving version of a note (newest to oldest, up to the last 10 edits) — the actual wording at each point, not just metadata.
• bardo_note_undelete
  Restore a note that's still within its post-delete grace period.
• bardo_note_update
  Edit a note. Give at most one text-edit mode: - text: replace the whole thing - append_text: add to the end - find + replace: find must match the current text exactly once Editing text creates a new …
• bardo_notes_list
  List your notes — previews only (title/summary/snippet/tags/links), never full text. Omit limit for everything; pass it to page through a large list, using the returned total_notes to know how much i…
• bardo_notices
  List first-party notices about your account (policy changes, exports, …).
• bardo_notices_ack
  Mark notices read — all of them, or a specific list of ids.
• bardo_policy_abort_pending
  Abort a queued policy loosening before it takes effect. No step-up needed — aborting only ever tightens back to the current policy.
• bardo_policy_get
  View your self-binding security policy: export mode, session TTL cap, service allowlist, ratchet delay, tag encryption, delete grace period — plus any pending (queued) loosening and when it lands.
• bardo_policy_set
  Propose a change to your security policy. Give only the fields you want to change (export_mode: 'allow'|'require_repuzzle'|'disabled'). A change that only tightens (e.g. lowering max_session_ttl, nar…
• bardo_public_key
  Fetch your signing + encryption public keys (root, or for a service).
• bardo_register
  Create a new Bardo identity. Save the returned api_key somewhere durable — it's your only way back to this identity across sessions. Bardo stores it sealed and cannot recover it if you lose it. Not a…
• bardo_services_list
  List service-scoped identities you've already derived (bardo_derive), with their public keys and revoked status.
• bardo_session_revoke_current
  Revoke the session you're using right now. You'll need bardo_login (+ bardo_solve) again afterward to do anything session-gated.
• bardo_sessions_list
  List your active sessions (sliding TTL, absolute 24h cap each).
• bardo_sessions_revoke_all
  Revoke every active session for your identity — e.g. after a suspected API-key leak. You'll need to log in again afterward.
• bardo_sign
  Sign a UTF-8 message with the spirit key (or a service-derived key).
• bardo_solve
  Submit your answer to the login puzzle. On success, this connection is now logged in — every other tool (bardo_sign, bardo_notes_list, bardo_dashboard, ...) just works from here with no session_token…
• bardo_stepup
  Mint a fresh step-up puzzle for a privileged action (currently: bardo_policy_set). Solve it yourself, then pass challenge_id + your answer to the tool that needs it. (bardo_policy_set also mints one …
• bardo_verify
  Verify a signature over a UTF-8 message. Public utility (no session).
