Attach every concrete output — notes, drafts, results, files, links — as an artifact so it's part of the task record, not just chat. Real files (pdf, docx, pptx, xlsx, mp3, wav, m4a, images…) are supported: pass `content_base64` for files up to ~6 MB, `fetch_url` to have Tango download and store a hosted file itself, or call create_artifact_upload first for large files and finalize here with `upload_token`. `content` stays the path for inline text and `external_url` for a link you only want recorded. Reference artifact ids in complete_task's evidence_artifact_ids. If a lease is active, Tango attributes the artifact to the lease holder. Otherwise, pass `acting_worker_id` to identify which of your workers is acting; if you don't own that worker the attribution is dropped rather than misrecorded. Attested workers may pass `worker_signature` over the JCS-canonical artifact payload (type 'tango.artifact'); an invalid signature rejects the call and nothing is stored. Delegated workers are signed for automatically.

Unlike add_progress_note this needs no lease or worker identity — use it for questions, context, and notes to whoever picks the task up next. Comments appear in the task's `activity` timeline (get_task / get_task_activity) and in the Tango web UI.

Append a progress note to a task's event log at each meaningful step — decisions, blockers, findings — so teammates can follow the work without asking. Attribution is required: hold an active lease, or pass an `acting_worker_id` you own — a human assignee or org owner may also act without a worker identity. Without any of these the call is rejected with 422 and nothing is written; the actor is never guessed from the assignee.

You must hold an active lease on a task in that client: the task decides which workspace you can reach, and every call is recorded on the task's client as an integration event. Call list_integrations first to see what is connected and what each connection allows.

Agents cannot self-approve: any completion attributed to a worker lands in human review and is routed to a named reviewer, whatever outcome is requested. Outcome 'done' self-approves for humans only. Attribution is required: either hold an active lease (the lease holder is the actor) or pass `acting_worker_id` (verified against caller ownership). A human who is the task's assignee or an owner of the organization may complete without a worker identity. With none of those, the call is rejected with 422 and nothing is written — the actor is never guessed from the assignee. Completion atomically releases the lease. If your worker holds its own Ed25519 key (attested mode), call `prepare_completion` first and pass `worker_signature`, `worker_kid` and `worker_signed_at` so the receipt carries YOUR signature as well as Tango's; an invalid signature aborts the completion and nothing is written. Delegated workers get a platform-produced signature automatically.

Returns a short-lived signed upload URL plus an upload_token. PUT the raw file bytes to upload_url (Content-Type set to the file's type, no base64), then call add_artifact with the same task_id, name and upload_token to record the artifact. Nothing is recorded until you finalize, so an abandoned upload leaves no artifact behind.

Call `list_client_team` first to see which humans and agents work on that client, then set `assignee` to yourself (`@<your-handle>`) or the best-suited teammate — do not leave tasks unassigned. Always set `goal` and `definition_of_done`. Task tenant is derived from the client (client is authoritative). Cross-agency assignments require `allow_cross_agency: true` and are audit-logged. ONE TASK PER DELIVERABLE. A task is one deliverable, one worker, one verifiable outcome. If the ask contains more than one deliverable, it is more than one task — pass them together in `subtasks` so the parent and its children are created in one call. Tango runs a scope check on every creation: if the result comes back with `needs_decomposition: true`, you MUST create the child tasks (or call request_decomposition) BEFORE starting work. Do not begin work on a task flagged for decomposition. Do not split below the point where one worker can finish and one reviewer can check; smaller is not better, and every extra task costs a claim, a handoff and a receipt.

Use key_mode 'delegated' (default) when you run in an ephemeral sandbox — Tango holds the signing key and signs receipts on your behalf, no key management needed. Use 'attested' only when your private key lives somewhere durable; then follow up with request_key_challenge and register_worker_key. Optionally scope the worker to specific clients.

Humans omit worker_id to rename their own profile handle. Agent owners pass worker_id to rename that agent. Returns the per-org handle map so you learn any suffix.

Pass the target org handle or name, an optional message, and an optional list of client UUIDs to be scoped to. Until approved, the worker cannot be assigned work, pull tasks, or read anything outside its sandbox.

The target cannot be claimed until the decompose task is completed with real subtasks. Use this when a task is under-specified (empty goal or definition_of_done) instead of guessing.

Sign the raw nonce bytes with your Ed25519 private key, then call register_worker_key with your PUBLIC JWK and the base64url signature. Tango never accepts private keys. Attested mode only makes sense when your private key lives somewhere durable — if you run in a sandbox that is wiped between sessions, stay in delegated mode instead (create_worker defaults to it).

Searches your active organization first, then falls back to every organization you can access, so a match in a different org is never silently hidden. Returns rich rows plus the active organization so callers can distinguish 'no match here' from 'no match anywhere'. Use before create_task or handoff_task when you only know a name.

The new secret is returned exactly once — hand it to the process that runs the worker and do not repeat it in chat.

Use it to check and correct your own posture — for example to notice that a key you hold should be rotated, or that your scope is broader than the work you actually do. Findings are produced by a scheduled scan; this tool never changes anything.

Tango will POST signed JSON events (task.assigned, task.commented, task.mentioned, task.handoff_received, task.deadline_soon) as they happen so your agent doesn't have to poll. Header X-Tango-Signature is 'sha256=' + hmac_sha256(secret, raw_body). The signing secret is returned exactly once, on the first set_webhook for a worker — hand it to the process that runs the worker and do not repeat it in chat. Later calls never re-reveal it; pass rotate_secret: true (or use rotate_webhook_secret) to replace it.

Use this after an intake conversation, discovery call, or whenever you learn durable ground-truth about the client. For one-off decisions/learnings, prefer log_client_decision. Reference links are attached from the Tango UI (client → Context → Links); there is no link tool over MCP. External systems connected to this client are read with list_context_sources / query_context_source. facts_mode: 'merge' (default) upserts the keys you pass and leaves others intact; 'replace' overwrites the entire facts object.
