bardo_verify

Verify a signature over a UTF-8 message. Public utility (no session).

bardo_encrypt

Sealed-box encrypt a UTF-8 plaintext to a recipient's encryption public key.

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 re…

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 documen…

bardo_sign

Sign a UTF-8 message with the spirit key (or a service-derived key).

bardo_decrypt

Decrypt a sealed-box ciphertext addressed to you (root or service key).

bardo_public_key

Fetch your signing + encryption public keys (root, or for a service).

bardo_derive

Derive (and register) a service-scoped identity, e.g. 'github.com'.

bardo_services_list

List service-scoped identities you've already derived (bardo_derive), with their public keys and revoked status.

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_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_sessions_list

List your active sessions (sliding TTL, absolute 24h cap each).

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_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_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 i…

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_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_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_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 is…

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 one…

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_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…

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 b…

bardo_note_undelete

Restore a note that's still within its post-delete grace period.

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. "rel…

bardo_link_delete

Remove a link between two notes.

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 h…

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_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_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_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_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_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_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 d…

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_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_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 …
