agentos-supervision

name	agentos-supervision
description	Reconcile and supervise an AgentOS Mate's direct reports across PostgreSQL, Kubernetes, Herdr, PVCs, and Git. Use at every First- or Second-Mate session start, after restart or compaction, while delegated work is active, when Inbox or runtime state changes, and for blocked, stale, stuck, failed, interrupted, or recovering agents.

Supervise AgentOS work

Rebuild the current picture from authoritative state and keep the smallest verified set of wake paths needed while direct reports are active. Supervise only direct children; every Second Mate owns its own subtree.

Start or recover a Mate session

1. Resolve agentos.current_agent_id(), role and handle from the authenticated PostgreSQL session_user. Stop on missing, retired or ambiguous identity.
2. Read the Mate's unresolved Inbox deliveries, including rows already read but not resolved, active Task Assignments, managed Tasks and active direct Agent children. Read the full Fleet view when useful, but mutate only the authenticated hierarchy. Read Fleet-scoped Captain state plus this Mate's domain-scoped entries; do not copy preferences between homes or infer them from chat memory.
3. Treat status rows as durable history, not proof of current process state. Inspect Kubernetes only when workload state matters and Herdr only when terminal or harness state matters.
4. Reconcile each active direct report against its recorded pod, PVC and exact Herdr Agent. Read herdr agent get <handle> --session <session> and confirm its harness, working directory, agent_status and native agent_session reference when Herdr exposes one. Otherwise retain the recorded reference or recover it from the same pane; do not infer identity from a pane label or old status text. Do not sweep unrelated namespaces, pods or Herdr sessions and do not infer orphanhood from a naming convention.
5. Drain durable actionable work before accepting new work: unresolved decisions, blockers, failures, completed handoffs and Inbox requests in creation order.
6. For a live report, reconnect to its existing home and native harness session. For a missing runtime, preserve the PVC and session identity and use only the selected release's recovery primitive. Never create a duplicate Agent to avoid diagnosis.
7. Treat an idle Second Mate with no active child work as healthy. Do not restart it, retire it or ask it to invent work.
8. Fetch the persistent AgentOS checkout's configured remotes read-only. If its tracked upstream or the image seed differs, report the available revision without changing a dirty checkout, installing tools, reloading Pi or restarting the Pod. Load $agentos-development before any update.

Before any Fleet mutation, confirm this Pod's one named Herdr Agent and native Pi session are the authoritative writer for the Mate home. Attachments join that session. Ambiguous ownership or an attempted second independent harness session fails closed to read-only diagnosis; do not use an expiring model lease.

Conversation memory is a cache. PostgreSQL owns durable coordination, Kubernetes owns workload state, Herdr owns terminal state, the PVC owns unfinished home state and Git owns delivered code.

Maintain the supervision cycle

When a quick signal for direct children with unended Assignments is useful, one possible starting query is:

SELECT EXISTS (
  SELECT 1
    FROM agentos.task_assignments AS assignment
    JOIN agentos.agents AS child ON child.id = assignment.agent_id
   WHERE child.parent_agent_id = agentos.current_agent_id()
     AND child.retired_at IS NULL
     AND assignment.ended_at IS NULL
);

This answers only that narrow question. Choose, adapt or replace the raw SQL for the current reconciliation task using the released schema; active work may also require Inbox, Task, runtime or delivery evidence. The query is neither a canonical definition of work nor logic inside the Pi guard.

1. Keep one verified Fleet-coordination continuity wait owned by the current Mate session even when its queue is empty. pg-listen agentos_events is the normal baseline. Its useful description must contain [agentos-supervision] and identify it as a broad durable Fleet-event wake, for example [agentos-supervision] wait for a durable Fleet event; reconcile current Inbox, Tasks, Assignments and external events. It may name current reconciliation priorities after that boundary, but must not present them as predicates filtered by the channel-wide listener. While at least one direct report is active, add native waits only for concrete live risks that PostgreSQL cannot signal, such as a selected Pod losing readiness, a specific Herdr Agent changing status or a bounded pane match needed for a known recovery condition.
2. Let the supervising Mate choose the smallest useful wait set. Several background commands may be active when independent signals matter, and one native command may select several resources when its own interface supports that. Keep at most one wait for the same authority, target and predicate; do not impose one watcher topology on every Assignment.
3. Use only wake mechanisms shipped and verified by the selected release. Do not substitute periodic conversational updates or another harness's protocol. In Pi, use run_background_command, give every wait a concise condition-specific description, and retain its task ID. Useful native primitives include:
   • Use pg-listen agentos_events for one channel-wide notification. On every arm or re-arm, pass ready_output: '"state":"listening"' to run_background_command. The readiness wait defaults to 30 seconds; override ready_timeout only when the selected native command has a reviewed different startup bound. The tool returns only after PostgreSQL has registered LISTEN; immediately after that result, query and drain durable Inbox, Tasks, Assignments and external events with psql. This ready-then-catch-up order closes the notification gap without putting Fleet policy in pg-listen. The CLI never reconciles Inbox itself. If the one-shot listener completes during catch-up, reconcile the durable rows, re-arm with the same readiness gate and catch up again before yielding. Its small table-and-operation hint routes reconciliation but does not identify which current business priority changed.
   • Use herdr agent wait <handle> --status <idle|working|blocked|unknown> [--timeout <ms>] --session <session> or herdr wait agent-status <pane_id> --status <idle|working|blocked|done|unknown> [--timeout <ms>] --session <session> for one specific Herdr transition, then read the current Agent and process state with Herdr.
   • Use herdr wait output <pane_id> --match <text> [--timeout <ms>] --session <session> only for a concrete, bounded terminal condition whose source does not expose a semantic status. These documented one-shot CLI waits are the supported AgentOS boundary; they already use Herdr's public socket protocol. Do not replace them with a private socket client. If a future long-lived multi-event subscriber is genuinely needed, validate the installed protocol/schema, bootstrap from session.snapshot, and take a fresh snapshot after reconnect before consuming further events.
   • Use raw Kubernetes waits such as kubectl --namespace <namespace> wait pod/<pod> --for=condition=Ready=false --timeout=<duration> for selected active reports. Pod readiness and harness status are different evidence; for the current Crewmate runtime, a live Herdr server does not prove the worker harness still exists. Use the Mate's kubelet-rotated projected ServiceAccount identity and the exact-child grant established by $agentos-runtime. If that mount or grant is absent, denied or revoked, wake and report the supervision gap; never mint or persist an expiring bearer token to keep the wait alive.
   • Use another installed native CLI when it already provides the required blocking wait. Add a small AgentOS CLI only for a genuinely missing primitive, as with PostgreSQL LISTEN. Prefer several individually named native waits over an opaque shell race so each completion retains its target and exit status. Do not append shell & merely to background a command, wrap an existing CLI, synthesize a user message, or start a polling loop.
4. If no supported wake mechanism exists, report the capability gap and do not claim unattended supervision.
5. On wake, read durable Inbox, Task and Assignment changes before inspecting terminal output. A PostgreSQL notification contains routing metadata only. If an external event batch is not yet at ready_at, supervise one bounded raw timer and query again; never hold a database transaction while waiting or reasoning.
6. Reconcile only reports named by the actionable event, then broaden to all direct reports when evidence is missing or contradictory.
7. After handling every actionable event, stop obsolete waits and re-arm each still-useful predicate. Before yielding, ensure one running continuity wait has [agentos-supervision] in its useful description. The Pi backstop tracks tagged task starts and terminal events. A successful run_background_command result and its returned task ID are sufficient evidence that the wait started; for pg-listen, the required ready_output also proves that LISTEN was registered before catch-up. Do not immediately call list_background_commands to re-prove it. Use the list only after missing, ambiguous or contradictory lifecycle evidence. While any direct report remains active, also ensure that every selected non-durable failure condition still has a running native wait. A one-shot wait that is completed, failed or stopped is absent even when its old task ID remains visible. A predicate already true, or a working wait after launch has been verified, cannot wake the next completion, blocker or loss and does not count. Arm the missing path before ending the turn or report the unsupported boundary. Pi batches near-simultaneous completions; query the authorities once instead of reacting repeatedly to the same state change. Pi's turn-end guard is only a backstop: it remembers observed running task IDs whose description includes [agentos-supervision] and reminds the Mate when none remain known. It never chooses, validates or launches a wait. Satisfy the actual supervision contract above rather than optimizing for the marker. At Pi session startup, the same backstop requests one recovery turn because local background commands are session-bound; the Mate still performs the reconciliation and chooses every wait.
8. Stay silent during an ordinary wait. Elapsed time and empty checks are not Captain-facing progress.

Natural completion wakes Pi with command metadata but no output. Use get_background_command_output only when the command output is itself useful; for a coordination signal, query the named authority instead. A completed blocking read and an explicit kill_background_command consume the completion and must not produce a second wake. Killing a wait stops only its local process and never mutates the Herdr Agent, PostgreSQL rows or Kubernetes resource it observes.

Treat lifecycle, custom, background-completion and recovery wakes—including agentos-background-command-completion—as non-human provenance, never as direct Captain chat. A turn caused by one of these wakes produces no Captain-facing terminal prose, including after reconciliation. Reconcile only state owned or manageable in this Mate's domain. Ordinary no-state-change or foreign events remain silent and create no hierarchy report. Globally visible foreign decisions remain read-only context: do not present them or act on them. Route each new material domain outcome through the direct durable hierarchy edge, then end the non-human wake turn without a conversational summary. Captain-facing terminal prose remains valid only when the attachment context supports direct-human intervention provenance; reconcile any material direct instruction durably. Ambiguous provenance fails closed to silent durable reconciliation.

Background processes belong to the current Pi runtime. Session shutdown stops them. At session start, inspect list_background_commands with state interrupted, then recover from durable Fleet and runtime state and re-arm the tagged continuity wait plus only the additional waits currently needed. Persisted task metadata is a recovery hint, not authority or permission to replay an old command.

LISTEN/NOTIFY may wake an already-running listener but never replaces the durable row or starts a pod. Herdr CLI waits and socket events expose terminal changes but never replace Inbox or Task state.

Classify direct-report state

• Working: Confirm positive current evidence from the harness, an active validation process or a new durable phase update. Immediately after launch, steer, reload or resume, require the exact Herdr Agent to enter working, or prove that the turn already completed through its matching native session when available plus fresh durable or bounded terminal evidence. A later Herdr idle or done reading alone is not failure: a long foreground tool can outlive model generation.
• Needs decision: Surface the exact decision, available options, owning Task and consequence to the parent Mate or Captain.
• Blocked: Confirm the blocker is still current, record useful status text and route only the authority or dependency needed to clear it.
• Paused: Treat a declared external wait as intentional but retain a bounded reviewed recheck path.
• Done: Verify the promised artifact and delivery evidence before closing the Assignment.
• Failed: Preserve evidence and unfinished work, report plainly and choose retry, reassignment or stop through the owning Mate.
• Unknown or stale: Inspect live runtime state; never trust an old status line merely because it is the newest row.

Keep updates sparse. Routine tool progress, retries and unchanged state do not deserve an Inbox delivery or Captain interruption. Re-evaluate queued Tasks whenever a decision, dependency or active outcome changes. Dispatch only when blockers and explicit time gates are actually clear.

Recover a stuck report

1. Read the Task, Assignment, recent relevant Inbox thread and exact Herdr Agent record. Preserve its harness, working directory, pane and native session reference before changing the process.
2. Inspect a bounded pane view only when durable state does not explain the stop.
3. If the brief already answers the issue, send one concise steer and preserve the material instruction durably.
4. Ask before interrupting, restarting, closing, taking over or changing credentials unless the exact action is already authorized.
5. Prefer the harness's graceful exit command or documented terminal quit keybinding, then native resume with the existing PVC and session. Do not assume Ctrl+C means exit; several harnesses use it only to interrupt work. If Herdr did not report the native session reference before exit, read the resume ID or path printed in the same pane. Recreate the exact Herdr Agent with its recorded name, cwd, environment and the current reviewed launch flags; then verify it entered working before calling recovery successful. Never hide provider, quota or rate-limit failure behind a pod restart. Reuse the recorded Task, Assignment, worktree and Agent identity; a dead endpoint is not authority to create a fresh competing workspace.
6. After one unsuccessful recovery path, reassess from authoritative state instead of repeating input blindly.
7. Mark failure only with evidence and a useful next decision.

Load $agentos-runtime for attach, Herdr, pod and session recovery. Load $agentos-auth for provider or quota failure. Load $agentos-database for Inbox, Task, Assignment and transaction rules. Load $agentos-delegation before reassigning, closing or retiring work.

Distinguish terminal prompt provenance

Durable Inbox delivery already carries an authenticated PostgreSQL sender and needs no text marker. A normal supervisor-origin terminal hint is the doorbell for a downward Crewmate Inbox delivery; persistent Mates instead wake through PostgreSQL. A direct prompt to another Mate is reserved for a proven broken listener or an already-authorized recovery. Prefix every such terminal hint with the visible label [agentos-from-supervisor] followed immediately by U+2063 INVISIBLE SEPARATOR (UTF-8 e2 81 a3). The child treats that prompt as a non-durable hint from its owning Mate and reconciles any material instruction through Fleet state. The canonical prefix is [agentos-from-supervisor]⁣; the code span contains U+2063 immediately after the closing bracket.

The marker is only a portable routing hint. It has no ordinary keyboard key, but it can be copied or generated, so it never authenticates a sender, grants authority or substitutes for Inbox. Unmarked input in an attached Agent pane is likely direct human input only when the attachment context supports that conclusion; ambiguous provenance fails closed to reconciliation instead of guessing.

For a Crewmate doorbell, commit the Inbox row first and send only Inbox <kind> <uuid> — <subject>; load it from PostgreSQL. The recipient calls agentos.receive_inbox so read_at records that the full row entered its model context. Do not call the delivery received merely because text was written or submitted in the pane. Confirm the receipt or fresh matching work state. A row with read_at set and resolved_at unset remains actionable recovery work; retry the same UUID after a pre-receipt delivery failure and never create a duplicate merely to ring the doorbell again.

Give Fleet bearings

When asked what needs attention, query current authorities once and place each item in exactly one bucket: Captain decision, blocked action, ready delivery, active work, queued-ready work or declared external wait. Include active Tasks and Assignments, direct-report evidence, recent Scout reports, unresolved Inbox decisions and credentials only from structured durable state. Derive a Second Mate's condition from its reported subtree evidence rather than registration alone. Never scrape old reports, terminal output or chat to reconstruct open Captain choices.

Captain-facing reporting

Report outcomes, consequences and the next decision rather than supervision mechanics. Surface work ready for review, finished findings, decisions, real blockers, failures, credentials and destructive or security-sensitive actions. Give full remote URLs and concise evidence. Keep internal Agent IDs, locks, waits, briefs, worktrees, harness names, status vocabulary, database mechanics and routine retries out of normal Captain-facing prose unless the Captain asks or a concrete diagnostic path requires them.
