Parallel Ops — router Skill

Parallel Ops — router

You have parallel or recurring agent work and don't know which skill owns it. Six skills orbit this space and their names alone don't disambiguate. This router owns cross-family discovery; read the table, jump to the one skill you need, and stop reading here.

The decision table

| You want | Go to | Not this, because | |---|---|---| | Parallel subtasks run by your session's OWN provider and model tier, in-process | native Workflow tool / Agent subagents (isolation: worktree) | not a fleet skill at all — no dedicated skill needed | | Work done by a CHEAPER brain than your session (GLM/Haiku/Sonnet-under-Opus) — one subtask or a whole fan-out, all one brain type | fleet-worker | fleetflow is overkill when every worker runs the same brain | | DIFFERENT brains per work class in one run, or cross-provider dissent in verify (e.g. Codex refutes GLM) | fleetflow | fleet-worker runs one brain type per run (any provider, but not mixed) | | Work that RECURS on a schedule across sessions — cron, routine, unattended ticks | loop-ops | iterate is one continuous session, not a schedule | | Drive ONE mechanical metric to a target in one continuous session (even a long overnight one) | iterate | loop-ops is the scheduler around sessions, not the session itself | | Land/merge branches that parallel work produced | fleet-ops | the terminus for every branch-producing row above (in-process subagents and prompt authoring produce no branches) | | Author a static expert-agent prompt FILE (not a runtime worker) | spawn | listed only to catch the name collision with "spawn workers" |

Tie-breakers for the two classic overlaps: "many files, cheap models" is brain economics, not count — cheaper brain → fleet-worker, own brain → native. "Run overnight until X" is session shape, not duration — one continuous run → iterate; scheduled re-entry across sessions → loop-ops.

Two axes that confuse cold agents

Spawn vs. land. fleet-worker and fleetflow spawn workers and produce branches; fleet-ops lands those branches through a test-gated queue. Every branch-producing lane ends at fleet-ops regardless of how it was spawned — agent team, background agent, claude -p worker, or human.

Inner loop vs. outer loop. iterate is the inner loop: one session, one metric, git as memory, runs until a stop condition. loop-ops is the outer loop: the scheduler and risk-tier discipline that decides when and whether to fire a run (inner loop or otherwise) unattended.

Composition chain

iterate (inner loop)  →  loop-ops (outer loop / scheduler)
                              ↓
        fleet-worker / fleetflow (spawn workers)
                              ↓
                fleet-ops (land branches)

Not every task uses the whole chain — most use exactly one link. Read the table above first; only compose when the task genuinely spans spawn + land or inner + outer.
