Raises XS's writer effort in quest's routing tables (src/cli/models.ts) from Haiku 5.5 high to xhigh, calibrated against mypriors.com/adamholter's score against subscription cost per task, on the maintainer's call rather than the m1 model check's tallies, which m0 found too thin (0 to 4 PRs per cell) to move anything.

Changes

	Before	After
XS writer	Haiku 5.5 high, then Sol low	Haiku 5.5 xhigh, then Sol low

• From that chart (index score, then subscription $ per task): Haiku high 30, $0.0034; Haiku xhigh 34.6, $0.0053, about Opus low (34.7, $0.015) and Sol low (34.8, $0.0094) for a third to half their cost.
• The guide (assets/AGENTS.md) now routes an iterate on a PR whose writer no list names, such as unknown or a retired model, to its size's first entry, as it did a PR with no known writer, since every model-id bump the model check makes leaves such PRs.
• README's table and the quest models XS example follow. quest/m1/model-check.md records the chart's numbers per model and effort as a calibration source for its run, the options rejected, and fixes its stale Opus review efforts.

Public API

quest models, quest unblocked --json, and quest review print and run the new XS effort. No flags or formats change.

Validation

• just check and just test pass (1183 passed, 5 skipped).
• A live probe on the maintainer's own login, with the environment cleared: claude -p --model claude-haiku-5-5 --effort xhigh answered, with a 1M context window.
• The first merge-queue run failed on 30 test timeouts and no assertion failures, while the self-hosted runner's host sat at load 55 to 60 on 32 cores; not this change. kixelated/nixos#42 gives the queue runners CPU priority.

Decisions

• How should XL route? ✅ Keep Opus xhigh for XL writes and for reviewing what Sol wrote (rejected: Fable 5.2 medium, which Anthropic's model guide favors over Opus past high, but which costs 30 to 300 times as much per task on a subscription for 4 to 7 points, and which CodeRabbit noted zero-data-retention organizations may be refused). Maintainer, 2026-11-09.
• What should XS write on? ✅ Haiku 5.5 xhigh (rejected: Haiku high as before; Sonnet 5.5 medium, which the guide favors for scoped coding but which scores 30.7 for $0.012 a task, below the frontier at every effort). Maintainer, 2026-11-09.

Reviewed commit: feca824

No actionable correctness findings. The direction is consistent: model choices remain centralized, the XL writer retains its Opus fallback, and the CLI output, reviewer selection, tests, and README agree with the new entries. I also checked nearest-size writer lookup and the model/effort arguments passed to Claude.

Verification limits: GitHub-only static review; I did not run tests or live CLI/provider probes. GitHub's build passed, while platform checks were still running. The reported Fable context-window limitation and Bedrock/Vertex/Foundry compatibility remain unverified by this review, as do the cost/quality claims motivating the change.

Walkthrough

The XS Haiku writing effort changes from high to xhigh. The README, CLI tests, and model-check plan record this update and related model information. A reviewer comment now says Claude reviews Sol’s work. Coordination instructions extend the first-available-model fallback to unlisted writers, including unknown or retired models.

Merge Risk: Low · up to a6abd

The incorrect cost comparison could mislead a future routing audit. Correct it before using the plan to choose S-size models.

Reviewed commit: 4c7bb83

No new actionable findings. Compared with my previous reviewed head feca824, the base is unchanged and the only file change is the coordination rule in assets/AGENTS.md:187. Routing iterates whose writer has retired to the size's first available entry addresses the gap left by removing Haiku. The CLI's explicit unknown-writer error remains intentional; the coordinator chooses the replacement.

Verification limits: GitHub-only static inspection of the delta, writer lookup, and coordination/iteration guidance. No tests or live model/provider checks run. The existing Fable availability/retention concern is not resolved by this change, and its vendor-policy premise was not independently verified here.

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

The queue log reports 15 timeouts across seven test files. For example, lines 1149–1151 say:

FAIL test/agent.test.ts > Codex crash releases scratch and resume restores the registered checkout
Error: Test timed out in 5000ms.
If this is a long-running test, pass a timeout value as the last argument or configure it globally with "testTimeout".

The PR merges cleanly with base, and just install and just check passed on a scratch merge. No evidence ties the queue timeouts to this PR, so no PR is blamed. The cited agent test passes when run alone on base.

Local validation is blocked by an unrelated reproducible failure: bun run vitest run test/usage.test.ts fails on both base and the scratch merge at line 407 because the expected OWNED session is missing. Its fixture assumes /work is a deleted checkout, while /work is the live repository here; checkoutRepositories therefore reads the real checkout instead of falling back to the fixture log.

The full just test run also reported a failure in the unchanged review gateway test before I interrupted the remaining run. The later shell, build, and lifecycle steps were consequently not reached. I cannot certify a passing full check or confidently classify the original timeouts. No source changes, test skips, or commits were made, and pr-590 remains at its pinned head.

Reviewed commit: 0365b6c

No actionable findings in the changes since 4c7bb83; the PR base is unchanged. XL writing and Claude reviewing are consistently restored to Opus xhigh across the tables, tests, README, and model-check plan. Removing Fable from both defaults addresses the previously discussed Fable-specific availability/retention concern. The narrower XS Sonnet change and retired-writer coordination rule remain intact.

Verification limits: GitHub-only static review; no tests or live model/provider probes run. This head's build is still running. I have not independently established the cause or resolution of the earlier merge-queue test failures.

One low-priority finding:

• [P3] Correct the S-tier cost comparison in quest/m1/model-check.md:96–97. It says Sol medium costs less than Opus low, but the figures immediately above are $0.021 versus $0.015 per task: Sol medium costs 40% more. Please correct that claim so the planned S-tier audit weighs the higher score against the higher cost, rather than treating it as cheaper.

Otherwise, the XS switch from Sonnet medium to Haiku xhigh is consistent across routing, CLI tests, and README; the Sol fallback and reviewer choices are unchanged.

Verification limits: GitHub-only static review since 0365b6c, with unchanged base. No tests or live CLI/provider probes run; this head's build is still running. External benchmark figures and subscription-cost assumptions were not independently verified.

Correct the S-size cost comparison.

The figures above give Opus low as $0.015 per task and Sol medium as $0.021. Sol therefore costs more, not less. Correct the comparison so the next routing audit uses the stated trade-off.
