docs(subagents): explain how spawn_agent fills its five model slots - #7550
Conversation
When fewer than five models are featured, Codex fills the remaining spawn_agent slots with the next picker-visible rows by priority. Document which rows those are (routed rows at priority 5 alphabetically, or account-qualified native rows when account selectors exist), how to control the list, and that opencodex v2 guidance never names the filler rows. English plus the seven existing locale translations. Refs lidge-jun#7366

slots to say it fills up to five slots, not always five. Apply the same
maximum-count wording to every locale copy.

The FAQ said Codex always fills five slots; with fewer eligible picker rows (for example after v2 skips "disabled" rows) it lists fewer. Applied to every locale copy. Refs lidge-jun#7366

With one or more Codex account selectors, this is not how the routed-only path sorts: buildCatalogEntriesFromObservedState puts an unlisted unfeatured routed row at 1005, while a listed row is rewritten to 1000 + index * selectorCount (so at least the first listed row precedes the unlisted rows). If native account rows leave a spawn_agent slot open, following this advice can therefore advertise a listed model first—the opposite of the documented control; qualify it to catalogs without account selectors and update the locale copies.

There was a problem hiding this comment.
When an already-running Codex App/app-server predates the roster's catalog write, starting a new session on that process does not reload the catalog: src/codex/app-server-processes.ts treats it as stale precisely because it retains an in-memory copy. The new session can therefore continue advertising the old roster; limit this promise to sessions launched by a fresh process or tell users to reload/restart the Codex surface, and mirror the correction to the locale copies.

Summary
When fewer than five models are featured on the Subagents page, Codex's
spawn_agenttool still lists five models. The extra ones are whatever rows sort next by catalog priority, and nothing on the page or in the docs said so (#7366). This PR documents that fill behavior inguides/sub-agent-surface.mdand its seven existing translations (fr, ja, ko, ru, tr, zh-cn, zh-tw). No code changes.The new section Which models
spawn_agentadvertises covers:priorityand takes the first five.subagentModelsonly pins the lowest priorities, in roster order. It is not an allowlist.5, by provider and then model id alphabetically. Unfeatured native rows sit at100 + featured countor higher.1005.modelPickerOrder(routed-only vs. complete order, linked to Model ordering)."disabled"are skipped first. opencodex's{{roster}}guidance names only configured models, so filler rows appear only in Codex's own tool text.A short FAQ entry points to the section.
Every statement comes from current source. Featured ranks and the default routed, account, and native bands are in
src/codex/catalog/build-entries.ts(buildCatalogEntriesFromObservedState,nativePriority, retained-row re-ranking,applyFullModelPickerOrder). The five-row window and the v2disabledfilter are insrc/codex/catalog/subagent-roster.ts(effectiveSubagentRoster). The guidance roster filtering to configured models is insrc/server/responses/collaboration.ts. I confirmed the two catalog scenarios by running the builder and the sync merge in a scratch script:[e/m5, b/m2]: priorities 0 and 1, then the other routed rows at 5, then natives at 102. Window =e/m5, b/m2, a/m1, c/m3, d/m4.e/m5, b/m2, acct1/gpt-5.5, acct2/gpt-5.5, acct1/gpt-5.6-sol, with routed rows at 1005.Refs #7366. This PR does not close the issue: the dashboard hint is a separate UI track.
