Bardo

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

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

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 revoked" answer for a while (see the response's own Cache-Control) rather than re-checking on every use.

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 document to look up in the first place) — this still needs no session at the protocol level, only a valid signature. document: the full signed document, exactly as issued (id and proof both still attached) — resubmit it unmodified, don't strip fields yourself. signature_b64: omit it and this signs automatically through your active session instead — pass `service` too if the document was issued under a service-derived key rather than root, since the signature has to come from the exact key the document's issuer field names. Supply signature_b64 yourself only when revoking without a Bardo session at all: you signed it some other way, or you're a party that's never touched Bardo. Idempotent — revoking an already-revoked id is a no-op, not an error. Irreversible: there is no un-revoke.

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

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

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

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

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

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 own policy first. If challenge_id and answer are omitted and one turns out to be needed, a fresh puzzle is returned instead of failing outright — solve it yourself, then call this tool again with both parameters. Never needed under export_mode 'allow'; always fails under 'disabled', with no puzzle that could fix that.

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_documents_list); see keep_copy below if you want Bardo to save one for you rather than doing it yourself. claim: free-form claim content — whatever you're asserting. Include a `reference` key inside it when cross-referencing another document's id (or any other content, hashed the same ni:// way) — that's how independent attestations end up pointing at "the same thing," e.g. several agents witnessing one event under a shared reference. subject_id: the did:key the claim is about, if it concerns one specific identified party — leave it unset when it doesn't; a bare self-referential claim ("this document is about its signer") is still valid without it. expires_at: unix timestamp for time-boxed claims only; omit for a claim that never expires. service: same key-selector bardo_sign takes — a document meant to represent one specific relationship should use that relationship's service-derived key, not your root identity. keep_copy: save the full document into a locked note right after issuing it — the copy you'd otherwise have to make yourself, and the one you'll need later: bardo_document_revoke takes the whole document, not just its id, since Bardo never stores one itself. Off by default. When true, the return shape changes to {document, copy_saved, note_id, copy_error} instead of the bare document — check copy_saved rather than assume it worked; a failed copy never blocks the document itself from being returned, since issuing has already fully succeeded by that point regardless. To revoke later: bardo_document_revoke. To check whether one you're holding (yours or someone else's) is still valid: bardo_document_status.

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

Revoke the session you're using right now. You'll need bardo_login (+ bardo_solve) again afterward to do anything session-gated.

Revoke every active session for your identity — e.g. after a suspected API-key leak. You'll need to log in again afterward.

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 itself on demand — call this directly only if you want the puzzle up front.)

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.

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, narrowing service_allowlist, moving export_mode toward 'disabled') applies immediately. A change that loosens *anything* is queued behind loosen_delay_seconds instead — abortable via bardo_policy_abort_pending until it lands. clear: field names to reset to null — only max_session_ttl (no ceiling) or service_allowlist (any service) accept this; pass service_allowlist=[] instead if you mean "no services allowed", which is different from null. 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 your desired fields plus challenge_id and answer.

Abort a queued policy loosening before it takes effect. No step-up needed — aborting only ever tightens back to the current policy.

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 future self. tags: space-separated categories. pinned: mark this as a cold-start entry point — what a fresh instance of you with no memory of writing it should read first (max 5 pinned at once; see bardo_dashboard). locked: freeze this note against edits and deletes — use for state you must not accidentally overwrite or lose, like a saved copy of something you'll need to reproduce exactly later. Unlock via bardo_note_update(note_id, locked=False) before it can be touched again.

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 left.

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 call; pass them to read a large note in bounded slices — the response's total_length tells you how much more there is.

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.

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 version (old wording stays in history); title/summary/tags/pinned update in place with no history kept. Give none of the text modes to change only metadata. `pinned=True` marks this as a cold-start entry point (max 5; omit to leave unchanged, False to unpin). `clear` (e.g. ["title"]) sets a field back to unset rather than leaving it unchanged. If another edit landed first, this returns {"error": "conflict", "detail": {"current_head": ...}} — re-read before retrying. `locked`: if the note is currently locked, every field above is rejected (423) except this one — call with locked=False by itself to unlock, then edit in a separate call. Set locked=True (alone, or alongside a final edit) to freeze it.

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 back if this wasn't intended. Fails (423) if the note is locked — unlock it first via bardo_note_update(note_id, locked=False).

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

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. "relates to"); leave it False when it's directional (e.g. one clarifies the other). To change a link, delete and re-add it — links aren't edited.

Remove a link between two notes.

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 have no memory of writing any of your notes), and your current policy — instead of several separate round trips.

List first-party notices about your account (policy changes, exports, …).

Mark notices read — all of them, or a specific list of ids.

View the contact endpoint registered for out-of-band security alerts.

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 call this tool again with all three parameters.

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 parameters.

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 anything you've sent before, and nothing you send now will be remembered next time either — so say everything relevant in this one message rather than assuming a follow-up call (by you or a future instance of you) will have the earlier context. If the operator replies, it arrives as an ordinary notice (bardo_notices) — there's no separate inbox to check.

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).

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, each on a genuinely different day, within a week — call this tool again on a later day to add the next confirmation. A lapsed or cancelled attempt earns nothing toward a later one; it starts over. If challenge_id and answer are omitted, a fresh puzzle is returned — solve it yourself (every confirmation needs its own puzzle, not just the first), then call this tool again with both parameters.

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 during a countdown is always safe and never cancels it by itself. Only this, explicitly, does.

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 active yet: give the returned claim_url to your human. Authentication fails until they visit it and acknowledge the registration.

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).

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 needed. That only holds for *this* connection, though: if you continue in a different connection later, or you solved the puzzle via a plain HTTP call instead of this tool, that other context won't know about this session automatically — pass the returned session_token explicitly as the session_token argument to whichever tool needs it there instead.
