Alera Inter-Agent Orchestration
Use this skill for structured multi-agent work in Alera. The runtime-host owns lifecycle authority; do not emulate completion, cancellation, leases, or ownership with generic messages.
Preconditions
- Run inside an Alera terminal so
ALERA_TERMINAL_HANDLE identifies the caller.
ALERA_WORKSPACE_ID supplies the default workspace for task creation, direct spawn, coordinator runs, and terminal listings. Use alera orchestration current to inspect both inferred identities.- Use
alera version --json when CLI/host/skill compatibility is uncertain.
- Keep every coordinated task scoped to a workspace and coordinator. A workspace may have one active coordinator run; different workspaces may run concurrently. Tasks created for a run and injected worker terminals must match that run's workspace and coordinator.
Coordinator Workflow
alera orchestration --json task-create --task-title "Review Tests" --spec "Review automated test coverage"
alera orchestration --json run --agent codex --spec "Audit the repository"
alera orchestration --json run-list --workspace <workspace-id>
alera orchestration --json status --id <run-id>
Use --agent codex|claude|copilot|cursor|agy|opencode|pi|amp. The runtime may create workers through the built-in adapter registry. Stop scheduling with run-stop --id; add --cancel-active only when active work should receive cooperative cancellation. Run stop, task recovery, and dispatch interruption require the owning coordinator; --force is the audited administrative recovery path.
For direct assignment:
alera orchestration --json agent-spawn --agent codex --task <task-id> --title "Review Tests" --timeout-ms 90000
alera terminal --json wait --terminal <handle> --for dispatch-accepted --timeout-ms 60000
agent-spawn creates the dispatch before launching Codex and supplies a short first-turn bootstrap that tells the worker to accept and read its context. Other adapters use hook-based readiness injection. Its --timeout-ms value may not exceed the host acceptance limit of 90000 milliseconds. A startup failure removes only a terminal created by that spawn; add --keep-on-failure to retain it for diagnosis. Reused terminals are never removed.
Manual fallback is:
alera orchestration dispatch --task <task-id> --to <handle>
alera terminal write --handle <handle> --text "<returned bootstrap>" --submit
The default dispatch response returns the short bootstrap. Use --return-preamble only when the complete preamble is explicitly needed. If an agent is confirmed idle but its hooks are unavailable, dispatch --inject --assume-agent codex is an audited override.
Worker Contract
The dispatch preamble installs a terminal-scoped context. Execute acceptance before doing work:
alera orchestration dispatch-accept
alera orchestration --json context
Use context-aware lifecycle commands:
alera orchestration heartbeat --phase reviewing
alera orchestration escalate --subject "Blocked" --body "Missing credentials"
alera orchestration complete --summary "Review completed" --completion-kind success --artifacts '[]' --files-modified "path/a" --validation '[]'
If the task defines a custom result schema, add its properties with --result-extra '{"field":"value"}'.
complete is atomic and required exactly once. completion-kind failure consumes execution failure budget and may return the task to ready.worker-done --task --dispatch --summary is the idempotent explicit recovery form.- Never use
send --type worker_done, send --type heartbeat, or arbitrary task status mutation; protocol v2 rejects them.
- After successful completion, stop the turn. Default policy returns immediately and leaves the terminal open for reuse.
- Use
ask for coordinator questions. While a dispatch is active, the host routes the question to the dispatch's current durable coordinator even if the run was transferred after its preamble was injected. Do not open a local user-input prompt the coordinator cannot see.
Tasks, Gates, And Recovery
alera orchestration task-list --run <run-id>
alera orchestration task-show --id <task-id>
alera orchestration task-wait --task <task-id> --for completed,failed,stalled --timeout-ms 300000
alera orchestration gate-create --task <task-id> --question "Choose approach" --options '["A","B"]'
alera orchestration gate-resolve --id <gate-id> --resolution "A"
alera orchestration task-cancel --id <task-id> --reason "No longer needed"
alera orchestration task-recover --id <task-id> --status ready --reason "Worker inspected and stopped"
Cancellation propagates to unstarted descendants, including tasks created after a dependency was already cancelled. Lease expiry produces stalled, keeps the concurrency slot occupied, and never silently redispatches work. Recovery and forced lifecycle mutations require a reason and are audited. Transfer a complete run rather than one of its owned tasks.
alera orchestration transfer-coordinator --task <task-id> --to <handle> --reason "Handoff"
alera orchestration transfer-coordinator --run <run-id> --to <handle> --force --reason "Coordinator crashed"
Self-dispatch is rejected unless --allow-self-dispatch is explicitly supplied for a protocol test.
Messaging And Diagnostics
alera orchestration send --to <handle|@group> --subject "Status" --body "Details"
alera orchestration inbox --terminal <handle> --direction inbox
alera orchestration inbox --terminal <handle> --direction outbox
alera orchestration check --wait --types escalation,decision_gate --timeout-ms 300000
alera orchestration terminal-show --handle <handle>
alera terminal list
alera terminal read --handle <handle> --max-bytes 65536
alera terminal write --handle <handle> --text "continue" --enter
alera terminal write --handle <handle> --stdin --submit
alera terminal prune
alera terminal prune --apply
--enter sends content first and a separate delayed carriage return. Use --submit for bracketed-paste TUI input. terminal prune is dry-run by default and only removes stopped terminal tabs when --apply is present.
Use --body-file or --body-stdin for multiline content. Operational messages become expired or obsolete when their scope ends. List commands return {kind, items, filters}; use items in automation. Terminal and task waits are held by the runtime host and make a final state check at timeout.
For the compact command contract at runtime, call alera orchestration worker-help.
