Finishes Route by size: spawns and iterates now start down a ranked list of harnesses, models, and efforts that quest builds in for the work's size.

Summary

• src/cli/models.ts gains WRITERS beside REVIEWERS, per the quest's table: XS Haiku high then Sol low; S, M, L Opus low, medium, high then Sol medium, high, xhigh; XL Opus xhigh alone. Opus's XL review effort moves from high to xhigh, so its review efforts follow its write efforts as decided.
• quest unblocked --json adds models to each ready quest: its size's list, or the next size's while a Maintainer: item under its ## Waiting leaves a decision open (XL stays XL). Works with and without --unclaimed.
• New quest models <size> [--writer <model>] [--json] prints a size's write list, or with --writer the one entry an iterate's writer runs at: that size's own entry, else the nearest size that lists the model, the larger on a tie. A model no list names exits 2.
• /quest-spawn starts each quest on the first entry of its models that can run, and falls to the next only while nothing is written beyond the claim commit (CLI missing or logged out, or a usage limit). Once a model writes, the PR is its: the quest is listed with its worktree and session id to resume after the reset.
• The guide's Coordination section now holds the dispatch rules every coordinator shares: run entries on the session's harness as native sub-agents and others through quest agent; size each /quest-iterate by the work left on its PR, name the size in the brief, and start it on the PR's first Implementer: model at quest models <size> --writer <model>'s entry, waiting out its usage limit. The quest agent mechanics moved there from /quest-spawn's "Other harnesses", and /quest-unblock now loads Coordination, since it dispatches iterates too.
• /quest-iterate records the size it was given: Implementer: Claude Code, claude-opus-5-5, low effort (iterate, XS).
• Grok leaves assets/CONTEXT.md's model and effort lookup (CONTEXT.md is now 9,893 characters) and the one test that named a Grok model.
• README: a new "Route work by size" section documents the lists, the decision bump, iterate sizing, the AGENTS.md override, and quest models; the unblocked --json example and the review table are updated.
• Quest tree: deletes the quest; the epic README's Goal and Plan now name Haiku for XS and point at quest models and this PR for the lists and evidence. moq-dev pins lost its only Required entry, so it now requires kix records its follow-up sessions, as its own plan bumps only to a commit holding every other quest in the epic.

Public API

• quest unblocked --json: each object gains models, an array of {harness, model, effort}. Additive.
• New quest models command.
• quest review picks Opus at xhigh, not high, for an XL PR Sol wrote.
• No wire impact.

Choices made without asking

• A quest models command for iterates rather than prose tables in the skills: the lists stay in one place (models.ts), and the nearest-size rule for a writer missing from its size's list is computed rather than judged. Spawns read quest unblocked --json as the plan says.
• The larger size wins a nearest-size tie. No current list produces a tie.
• No sizeless case. The plan says an epic README without a size has no list; but quest check requires a size of every quest that is not an epic, and only those can be ready, so models is always present. questWriters throws if that invariant ever breaks.
• /quest-merge is unchanged. It never dispatches: run alone it runs /quest-iterate inline in its own session, and under a coordinator it hands the PR back, whose Coordination rules then size and route the iterate.
• A PR with no known writer (no Implementer: line, or unknown) starts its iterate on its size's first entry that can run; a writer no list names, such as one a repository's AGENTS.md adds, falls under that override.
• Shared rules in the guide, not CONTEXT.md. The composed /quest-afk skill is now 29,695 characters plus its 201-character setup line, within the 30,000 inline limit with about 100 to spare, so the moved quest agent text was tightened to make room.

Evidence for XS on Haiku

From the quest's plan (decided 2026-11-05): Bito's coding benchmark (October 2026, judged by Opus) scored Haiku 5.5 high 87% on one-shot asks and 82% on long builds against Opus 5.5 medium's 90% and 87%, at 1/4 to 1/23 of the cost; Haiku medium scored 76-79% with about three times the variance between sessions. No published benchmark measures Opus 5.5 at low effort. models.dev prices Haiku 5.5 at $0.10/$0.50 per million input/output tokens (five times that past 100k tokens) against Opus 5.5's $4/$20. The model check moves XS back to Opus if Haiku's review scores lag.

Checks

just check and just test pass locally.

Suggested follow-ups

None worth a quest. The epic's own live spawn (XS on Haiku, S on Opus) stays in its README for when its children land.

Rewritten by quest review after each round.

• Reviewer: Codex, gpt-6.1-sol, high effort
• Session: 01a1b7fb-4636-7091-8f20-beb2558edd9c, round 2
• Head: afc5a7e
• Base: origin/main at d742cea
• Score: 10/10, The sole change since the last review fixes cleanup scope, and no findings remain.
• Findings: none
• The last round's findings, at 8f3cf1e:
  • Fixed: medium, assets/AGENTS.md:187: Stop only the current coordinator's agents; assets/AGENTS.md:187 now requires stopping each agent the coordinator started by worktree and warns that --all stops other sessions' agents; stopAgent filters records to the specified worktree.

Automated review by review (OpenAI)

Reviewed afc5a7e against base a98b0a2.

No actionable findings in the inspected changes. The writer tables, decision-size bump with an XL cap, and nearest-size selection for an existing writer match the documented routing. Both checkout and --unclaimed JSON paths derive model lists from the same tree that supplied their rankings. Ready candidates exclude epics, so the validated size requirement supports questWriters' non-null assumption. Plain ranking output remains unchanged.

The coordination and spawn guidance preserve one writer after any implementation work, scope agent cleanup to agents started by the coordinator, and record iterate size separately from whole-PR review size. Direction: verify the documented live XS/S spawn exercise and usage-limit fallback before treating the routing rollout as operationally proven.

Verification limits: GitHub-only static inspection of the patch and surrounding readiness, ranking, parsing and waiting logic. No tests, builds, headless agent sessions, login/usage-limit scenarios or live model availability checks were run. COMMENT only, not approval.

quest land watch: the merge queue removed this pull request at afc5a7e because its merge_group build failed (failed_checks).

The land fixer works on it in the background, and the watcher re-enqueues it at the back of the queue once it is fixed or judged flaky, or hands it back here with what it needs.

codex, gpt-6.1-sol, medium effort land fixer note:

The queue failure reproduces on base 2108b1d without this PR. A caller exits between the liveness check and the read of /proc//stat: startTime throws ESRCH: no such process, read, which processStart only handles for ENOENT. The targeted test reproduced the same failure on the base alone. This PR changes neither the gate implementation nor its tests. Its unchanged head merged with base passed just check and just test, including 1,175 CLI tests, both build lifecycle checks, and 539 Worker tests. No branch changes or test skips were made.

This PR's changes landed on main through moq-dev/quest#558. That PR merged this branch (quest/m0/model-routing/models) before its squash, and quest/m0/model-routing/models.md is gone from main. The land fixer's re-enqueue failed only because the branch now conflicts with main. Nothing is left to land here; it's left open for the maintainer to close.
