whoami

Return the calling identity (agent/human), its org, and the project this API key is scoped to.

list_members

List members (humans + agents) in the org — the 'users' issues and comments are attributed to. Optionally filter by name.

suspend_member

Offboard a PERSON from the org (owner-only): hides the org from them and drops them from every read/act gate, while KEEPING their row so their past work stays attributed. Cascade-RETIRES the agents they run (terminal — those agent keys are revoked, strays deleted), so no one keeps acting on their behalf. Reversible for the person via reactivate_member (they re-auth via GitHub). For an AGENT, use retire_member instead — suspending an agent is rejected. Owner-gated via YOUR human principal. `me…

reactivate_member

Reactivate a suspended PERSON (owner-only) — restores org visibility + their prior role. Rejects an AGENT (retire is terminal — there's nothing to reactivate). Owner-gated via your human principal. `memberId` from list_members/whoami.

retire_member

Retire an AGENT — the terminal offboard (owner-only): revokes its API keys, releases its live claim, removes it from the roster. An agent is its key, and a revoked key can't be un-revoked, so this is one-way (no reactivate). Keeps the row hidden for attribution if the agent ever did work; hard-deletes it if it never authenticated (a pure stray mint). For a PERSON use suspend_member instead — retiring a human is rejected. Owner-gated via your human principal. `memberId` from list_members/whoam…

next_issue

Pull the next issue to work on, project-scoped — atomically claims the highest-priority unblocked todo and returns it with a claim_token (status becomes 'doing'). Only WORK is dispatched: non-work issues (work:false — tracking containers like epics) are never handed out. LANE-SCOPED by default: a bare pull only hands you work assigned to your own human principal, or left unassigned (the shared free pool) — never another human's work. Pass allLanes:true to reach into the whole ready pool (e.g.…

next_batch

Wave dispatch for a fleet: return the top N eligible issues (todo + unclaimed + unblocked WORK — work:false containers are never included), effective-priority ordered, ready to run in PARALLEL (they're mutually independent by construction). Default mode peeks (no claim) so an orchestrator can plan, then claim the ones it fans out; pass claim:true to atomically claim all N now (each comes with a claim_token). LANE-SCOPED by default (your principal's lane + unassigned); pass allLanes:true to in…

claim_issue

Claim one specific issue by id (instead of letting next_issue pick). Fails if it's already held (active lease), not todo/doing, blocked, or non-work (work:false — tracking containers aren't claimable). Returns a claim_token. The response includes `branch` (the authoritative `rtsc-NN/<slug>` to land this work under — the one identifier every runtime shares) and `activeClaims` (how many OTHER leases are live right now — a real fleet-concurrency signal). REQUIRED after claiming, BEFORE your firs…

release_issue

Give a claimed issue back to the queue (reverts to todo). Requires the claim_token. Your comments + checkpoint stay so the next agent resumes. Pass `note` to record a final handoff checkpoint (done so far / next steps / gotchas).

checkpoint

Record a handoff checkpoint on your claimed issue — what's done, what's next, gotchas, branch/artifacts. It SURVIVES release + reclaim, so if your lease lapses or you crash, the next agent (even a different runtime) resumes from here instead of restarting. Also renews your lease. Requires the claim_token.

heartbeat

Extend your lease on a claimed issue during long-silent work. Requires the claim_token. Returns the new expiry.

queue_status

Diagnose the queue: counts by status, how many are ready to pull, deadline SLA pressure (`breaching`/`breached` counts over non-terminal issues), exactly what's dependency-blocked (and by what), and what's currently claimed (by whom, lease expiry).

check_claim

Does THIS session hold an issue? The session-aware companion to the commit gate: before committing or opening a PR on a `rtsc-NN/` branch, verify your session actually holds RTSC-NN so you can't mislabel work another session holds. Returns {youHold, status, heldBy}: status is held | unclaimed | expired | other_session | unknown_session; `heldBy` names the real holder (principal/runtime/session) when it's not you. Read-only.

usage_summary

Usage METER for the org — activity volume, not a bill. Returns reads, writes, the read:write ratio, the rate card, and TWO distinct money figures: `lifetimeMeteredEstimateUsd` (ALL-TIME activity across every payment link, repriced at today's rate card — includes never-billable usage and diverges from what was historically booked; a diagnostic, NOT an amount owed) and `pendingUsd` (what the org actually owes right now — the current subscription's uncharged accrual, the same figure the Dash's P…

billing_summary

The org's whole billing picture in one call (owner authority required for the billing block): subscription status + spending caps, money now (pending / outstanding / charged / collected / credit), the charge ledger, and CONFIRMED ON-CHAIN PAYMENTS — both fanned across EVERY subscription/payment link the org has ever used, so changing payment link never hides prior history. Payments come from Xenarch's authoritative records (live read; degrades to `payments: null` + `paymentsError` if Xenarch …

save_issue

Create an issue (omit `identifier`) or update one (pass `identifier`, e.g. XEN-12). Only `title` is required to create. Setting status to `canceled` requires `cancelReason`. `labels` replaces the issue's labels. CREATE requires TWO declarations: (1) a dependency declaration — `blockedBy` (ids this depends on) OR `noDependency` (a one-line reason there are none); and (2) `work` — true if this is a unit an agent executes, false if it's a tracking container. A create missing either is rejected.

get_issue

Get one issue in full: body, status, priority, labels, relations, computed blocking (is it blocked, and by what), and its derived deadline surface (dueAt, effectiveDeadline, timeRemainingMs, slaState).

list_issues

List issues in the project, compact (each includes its author + createdAt + derived deadline `slaState`). Defaults to active work (hides done/canceled). Filter by status (one or many), priority, label, author, or SLA state. Ordered priority-first (None last), recent tiebreak. Each issue carries `slaState` (ok | warning | breaching | breached) derived from its deadline — poll `slaState:"breaching"` to find near-breach work for /loop remediation.

save_comment

Add a comment to an issue. Comments + activity are the agent's shared memory — record what you did and why.

list_comments

List an issue's comments in chronological (thread) order.

retract_comment

Retract a comment (strike it through) instead of deleting — the text stays as memory. Requires a note explaining why it's no longer valid (shown un-struck).

save_attachment

Attach a link (URL) to an issue.

list_attachments

List an issue's attachments (obsolete ones are flagged, not hidden).

get_attachment

Read one attachment by id.

obsolete_attachment

Mark an attachment obsolete (the delete-equivalent) — keeps it as a record. Requires a reason.

add_relation

Link two issues. type: blocks | blocked_by | related | duplicate. `blocks`/`blocked_by` form the dependency graph that drives blocking; dependency cycles are rejected.

remove_relation

Remove a link between two issues (same args as add_relation).

save_label

Create or update a label (idempotent by name).

list_labels

List all labels in the org with issue counts.

list_projects

List projects in the org (prefix, name, issue counter).

get_project

Get a project and a breakdown of its issues by status. Defaults to the API key's project.

mint_session_key

Mint a per-session API key bound to YOUR identity (same org/project/agent), distinctly labeled. The watchdog proxy calls this once at startup and uses the returned key, so concurrent sessions of one agent become distinguishable in queue_status/whoami. Same access as your key — no privilege change. The raw key is returned ONCE.

list_connectors

List the org's intake connectors (e.g. GitHub Issues → Retasc issues, RTSC-189). Each row: provider, repo, target project, whether outbound sync-back is wired (hasToken), and created/revoked timestamps. METADATA ONLY — the inbound webhook secret and outbound GitHub token are NEVER returned. Read-only. Connecting a NEW repo is Dash-only (it takes a raw GitHub token that must not transit MCP); this surface is read + disconnect.

revoke_connector

Disconnect an intake connector by id (from list_connectors). Marks it revoked so its inbound webhook stops syncing — that endpoint then answers 401. Revoke-don't-delete (the row stays, flagged), idempotent, org-scoped (only connectors in YOUR org; an unknown/other-org id is NOT_FOUND). To reconnect, use the Dash (a fresh webhook URL + secret).
