feat(claude): expose Ultracode on Claude Sonnet 5.5 and Haiku 5.5#30781
Fixes pingdotgg/t3code#30780
Problem
Claude Code supports Ultracode on Claude Sonnet 5.5 (CLI 2.1.284+) and Claude Haiku 5.5 (CLI 2.1.293+), but the model manifest only offered it on the Opus and Fable profiles, so T3 Code never showed the Ultracode toggle for those two models.
Change
- Added the
ultracodeoption to thehaiku-5-5profile. - Gave
claude-sonnet-5-5its ownsonnet-5-5profile with the same option. It used to sharesonnet-5withclaude-sonnet-5, so adding Ultracode there would have also offered it on Sonnet 5.
No effortMap.ultracode entry: servers turn the manifest's ultracode effort level into the Ultracode toggle (#27034) before any effort mapping. Old saved effort: "ultracode" selections still become xhigh with Ultracode on.
Verification
Ran a real Haiku 5.5 turn on a dev server from this branch, at Low effort with Ultracode on. Claude Code launched with --effort=low --model=claude-haiku-5-5 --settings {"ultracode":true,…} and replied. Selections compile as expected: Sonnet 5.5 and Haiku 5.5 get Ultracode at any effort, and Sonnet 5 never does.
Released servers pick up this manifest from main and will show Ultracode for these two models, but they start turns from their bundled catalog, so it has no effect there until they update. A follow-up PR makes turns use the downloaded catalog.
Authored with Gemini 4 Argon in T3 Code; Sonnet profile split and verification by Claude Opus 5.5 in Claude Code.

Approvability
Verdict: Approved at 3fab01d
Macroscope's review found this PR approvable — Adds opt-in Ultracode reasoning for Claude Sonnet 5.5 and Haiku 5.5 using existing adapter support. Existing reasoning defaults remain unchanged, limiting the effect to users who select the new mode.

The model manifest adds a Sonnet 5.5 profile with reasoning options and a fixed context window. It adds Ultracode to Haiku 5.5 and updates Sonnet 5.5 to use the new profile.

The issue also requests catalog unit coverage.ClaudeModelCatalog.test.tstests a synthetic model but does not test Ultracode for either 5.5 model. The manifest does not add the proposedeffortMap.ultracodeentries. The PR description says the server handles Ultracode before effort mapping, but the available inspection does not independently verify that behavior.Resolution

Not verified
native ios/android and electron clients, macos/windows, and remote/relay/tunnel connections were not exercised on this linux vm. claude requests used the local proxy rather than a direct anthropic subscription. this verifies option selection, persistence, provider flag propagation, and successful responses; the short prompts did not exercise ultracode's multi-agent workflow orchestration.

Takeover update
merged main into the branch with a merge commit (14206b5920). the only conflict was the manifest updatedAt; kept the pr's newer date. the pr diff is otherwise unchanged. vp run check:changed and the catalog and manifest tests pass, and all 29 ci checks are green.
coderabbit's outside-diff note: legacy claude-sonnet-5 shares the sonnet-5 profile, so it also gets ultracode. that is intended. the manifest already offers ultracode on every profile with xhigh effort, including the older opus-5 and opus-4-8.
