Symptom: every @ops / @lead run has failed since the xAI migration (PR #114/#115). Latest: gitea/ops run #1406 (issue #15), job https://git.ffaerber.duckdns.org/gitea/ops/actions/runs/1406/jobs/2545 — "Run agent" step failed in ~2.3s with rc=1, empty stderr, 1-line event stream.

Root cause (reproduced locally): opencode ships a built-in model-catalog entry for a provider named xai (a real @ai-sdk/xai integration with Responses-API support — opencode models lists xai/grok-4.5 etc. out of the box). Our install-opencode.sh also names its custom OpenAI-compatible shim xai. That name collision confuses opencode: once a permission block is present in opencode.json (which it always is in this pipeline), the --auto permission-check path assumes the catalog's provider object (which has .responses()) instead of our openai-compatible shim (which doesn't), and crashes:

{"type":"error",...,"error":{"name":"UnknownError","data":{"message":"Z.responses is not a function. (In 'Z.responses(Q)', 'Z.responses' is undefined)"}}}

Confirmed by reproducing with the exact production config shape (provider block + permission + mcp) on opencode 1.17.13 in a fresh $HOME: fails 100% of the time with provider key xai, succeeds every time after renaming the key to xai-oc (model id becomes xai-oc/grok-4.5).

This also explains why @senior's earlier attempt (PR #110, issue #12) was never validated end-to-end — it used the same colliding xai key and would have hit this too, just never got a live run before the PR-open bug (issue #111) buried it.

Fix: rename the provider key from xai to xai-oc in install-opencode.sh, and update agents.json model ids (xai/grok-4.5 → xai-oc/grok-4.5) plus README/comments accordingly. Opening a PR now.

Let me verify the key claim — that opencode's built-in catalog ships an xai provider that collides with our custom one.
Let me verify the proposed xai-oc key doesn't itself collide with any built-in catalog entry, and confirm the scope of changes.
Diagnosis confirmed and correct. I verified the root cause directly:

Built-in catalog collision is real. opencode models on the pinned 1.17.13 lists a built-in xai provider (xai/grok-4.5, xai/grok-4.3, etc.) — the @ai-sdk/xai integration with Responses-API support (.responses()). Our install-opencode.sh:56 declares a separate custom provider also keyed xai but backed by @ai-sdk/openai-compatible (no .responses()). Same key, two different provider objects. The --auto permission path picks up the catalog's object and calls .responses() → Z.responses is not a function. The reproduction (100% fail with xai, 100% pass with xai-oc) matches exactly what I'd expect from that collision.

Why ollama/ollama-cloud don't crash but xai does: those keys also collide with built-in catalog entries, but the built-in ollama/ollama-cloud providers are themselves openai-compatible shims (no .responses()), so the shape matches ours and the permission path is a no-op. xai is the only built-in with a richer API surface, so it's the only one that fractures. Latent risk: a future opencode release adding .responses() to the built-in ollama providers would break us the identical way. Out of scope for this fix, but worth a tracking note.

Fix scope (rename xai → xai-oc): I diffed every file. The change touches exactly 4:

• install-opencode.sh:45,51,56 — comment + XAI_MODELS select/sub prefix + provider key
• agents.json:28,46 — "xai/grok-4.5" → "xai-oc/grok-4.5"
• README.md:13,15,114 — model ids + the xai/… note
• build-activity-log.sh:41 — comment only (the cost-label case at :42 already routes xai-oc/… to the metered $ branch correctly via the *) fallthrough)

route.sh, run-agent.sh, agent.yml, publish.sh, rescue-pr.sh need no change — they either derive the model id from agents.json (route.sh) or reference only the XAI_API_KEY secret/env name, which should stay as-is (it's the x.ai API key, not the provider key; renaming the secret is pure churn). I confirmed xai-oc is not itself a built-in catalog entry, so no secondary collision.

Effort: ~10 lines across 4 files, all mechanical. Low risk, high confidence — the config is regenerated fresh every run by install-opencode.sh, so there's no stale-cache or in-flight-run concern. The maintainer opening the PR is the right call; I'd hand this to @junior if it weren't already in motion. Recommend the PR also add a one-line comment at install-opencode.sh:56 noting why the key is xai-oc and not xai (collision with built-in catalog), so the next person doesn't "tidy" it back and reintroduce the crash.
