fix: Harmoniqs AI missing from Connect Providers + every chat turn 400ing - #966
Merged

Conversation
…0ing Two independently-diagnosed bugs found while verifying v0.3.5-alpha.2: 1. Connect Providers dialog never showed "Harmoniqs AI" despite #327/#962 merging and opencode.lock.json being re-pinned to v1.18.29-amicode.29 (#963). Root cause: packages/app-bundle's overlay (which builds dist/app, the actual web UI shipped in the VSIX) is pinned independently via manifest.json's fork_tag -- still v1.18.10-amicode.21, 50 commits behind -- and nothing re-synced it after the lock-file bump. Confirmed by grepping the actual released VSIX: zero occurrences of "connect-harmoniqs-provider" anywhere in dist/app. Same class of bug as #952, the other pin. Fixed via a surgical backport, not a full re-extract: the overlay's dialog-connect-provider.tsx already carries a local-only OAuth browser-launch backport (from the alpha.6 fix) that predates this file's .21 snapshot. Confirmed v1.18.29-amicode.29's version is a strict superset (diffed against the current overlay file: the only delta is the new Harmoniqs entry code, the OAuth backport is untouched) before replacing it wholesale. Added the two new sibling files (dialog-connect-provider-harmoniqs.ts/.test.ts) and refreshed manifest.json via the package's own refresh_manifest.mjs -- diff is exactly the 3 touched files (2 new A, 1 M), nothing else. 2. Every real chat turn through a working, entitled Harmoniqs connection failed with the generic "Invalid chat completion request" (the unstyled invalid_max_tokens fallback, per chat-completions.ts's requestError). Root cause, confirmed by reproducing the actual outgoing request through the real @ai-sdk/openai-compatible + opencode pipeline: buildProviderConfigEntry() never set limit.output on the harmoniqs-auto model entry. opencode's own maxOutputTokens fallback (Math.min(model.limit.output, 32000) || 32000) treats the resulting unset 0 as "no cap" via the || and sends max_tokens: 32000 on every turn -- which exceeds this gateway's real 4096 ceiling. Add HARMONIQS_MAX_OUTPUT_TOKENS = 4096 and set it as models[modelId].limit.output. Verified: grepped the actual rebuilt VSIX's dist/app assets for "connect-harmoniqs-provider" (found). 82/82 onboarding_panel tests pass (6 new/modified assertions). 8/8 dialog-connect-provider-harmoniqs tests pass in the materialized app-bundle tree. Full pnpm --filter amicode run package succeeds end to end.
📝 WalkthroughWalkthroughAdds a conditional Harmoniqs provider entry to both provider pickers, implements iframe message handoff and acknowledgement handling, updates the app-bundle manifest, and sets a 4096-token output limit for Harmoniqs models. ChangesHarmoniqs provider support

Suggested reviewers: Merge Risk: 🔵 Low · up to Harmoniqs chat requests now use a 4096-token cap and the provider is added to the picker, but non-extension iframes may expose a nonfunctional entry and the regression tests do not independently pin the gateway limit. The change is low risk with bounded follow-up. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

Do not use iframe status as extension-host detection.
inAmicode() returns true for any iframe. The test setup documents this behavior. A non-extension iframe will show Harmoniqs and post the request to an ordinary parent that cannot handle the extension handoff. Gate this entry on an extension-specific bridge capability. Add a framed non-extension test that keeps the entry hidden.

Assert the gateway limit independently.
Both assertions compare the configuration with HARMONIQS_MAX_OUTPUT_TOKENS imported from the same production module. If that constant changes from 4096 to 32000, these tests still pass. Add an explicit assertion that HARMONIQS_MAX_OUTPUT_TOKENS equals 4096, then retain these propagation assertions.
