## Summary
- Bump catalog `@xsai/*`, `@xsai-ext/providers`, and `xsschema` to
**0.5.0-beta.8**, and delete the three `@xsai/*` pnpm patches — the
beta.2 ones from #1602 and the beta.8 regenerations that landed on main
in `38a008500`.
- Always capture tool failures on the core-agent chat path: xsAI beta.8
marks failed tool executions with `isError: true` on `tool-result.done`,
and `llm-service.ts` maps that to AIRI's `tool-error` event via
`toAiriStreamEvent`, so the agent loop continues instead of aborting.
- Remove the `captureToolErrors` request flag (and stop forwarding it
into `streamText`).
- Rebased onto latest `main` (`b230e16b2`). Includes one follow-up fix:
steps are marked settled before the finish listener runs, and finish
listener failures still reject the stream.
### Related
- Supersedes / follows up on
[#1602](https://github.com/moeru-ai/airi/pull/1602) (`captureToolErrors`
+ xsai patches).
### Scope of capture
| Case | Covered |
| --- | --- |
| A — unknown tool | yes |
| B — invalid / unparseable arguments JSON | yes |
| C — `validate` failure | yes |
| D — `execute` throw | yes |
| `missing_name` / `missing_arguments` | no (xsai still aborts) |
| `repairToolCall` | no |
Error copy on beta.8: `Tool "<toolName>" execution failed: …` (produced
by xsAI).
## Test plan
### Automated (Vitest)
- [x] core-agent `llm-service.test.ts` — 16/16
- [x] core-agent full suite — 82/82
- [x] stage-ui `llm.test.ts` + `chat.contract.test.ts` — 44/44 (the
previous `stepsSettled` timing failure is fixed in this branch)
- [x] stage-ui full suite — 594 passed / 0 failed (one
browser-test-runner teardown error, not a test failure)
- [x] typecheck — core-agent, stage-ui, component-calling, satori-bot
pass; telegram-bot fails only at `src/utils/velin.ts`, which is
pre-existing on main and untouched by this PR
### Real-environment E2E (rebase branch, DeepSeek V4 Flash via DeepSeek
API)
Harness: `/Users/lulu/GitHub/airi-e2e/pr2164/tool-error-e2e-rebase.mjs`
— drives the built `core-agent` `streamFrom` with a deliberately failing
tool.
| Case | Result | Evidence |
| --- | --- | --- |
| D — execute throw | **pass** | `tool-error` carried `Tool
"always_fail" execution failed: boom: deterministic tool failure`; the
model answered: "The always_fail tool threw a deterministic error as
expected." |
| A — unknown tool | **pass** | The model called the unavailable
`search_the_moon_database` after being told truthfully that this tests
AIRI's error capture; runtime returned `tool-error` and the conversation
continued. |
| B — bad arguments JSON | not observed on real model | providers rarely
emit invalid `arguments`; covered by unit test |
| C — `validate` failure | pass (earlier manual run with a temporary
validate-gated tool) | — |
Evidence artifacts:
`/Users/lulu/GitHub/airi-e2e/artifacts/pr2164/tool-error-e2e-2026-08-10T16-49-15-384Z.{json,log}`
### Notes / non-goals
- Fallout-only updates for the xsai beta.8 API rename: `textStream`,
`inputTokens` / `outputTokens` / `totalTokens` in component-calling /
telegram / satori.

## Summary
Adds a self-contained better-auth plugin
(`server/apps/api/src/libs/auth-plugins/steam.ts`) implementing Steam
OpenID 2.0 sign-in, account linking, and callback verification via "dumb
mode".
Steam's web login is OpenID 2.0, not OAuth2/OIDC, so it cannot be
registered as a `socialProviders` entry, and better-auth has no plugin
hook for extending its OAuth2 endpoints with a non-OAuth2 protocol. The
plugin therefore adds the endpoints Steam's protocol needs: `POST
/sign-in/steam`, `POST /link/steam`, and `GET /steam/callback`.
- Callback verification uses OpenID "dumb mode"
(`openid.mode=check_authentication`): one extra round trip to Steam
instead of managing RSA association state.
- New sign-ups get a placeholder `<steamid64>@steam.placeholder.local`
with `emailVerified: true`, mirroring Apple Sign In's
`<sub>@apple.placeholder.local`.
- The plugin's request/query schemas use Zod; a `// NOTICE:` documents
that better-auth's OpenAPI generator is Zod-native. Steam verification
uses `ofetch`.
- Wires Steam into `apps/ui-server-auth` sign-in and profile "Connected
accounts", plus the shared `OAuthProvider` / `defaultSignInProviders` in
`packages/stage-ui`.
- Linking routes through `/link/steam` via the client's `$fetch`;
unlinking needs no special-casing (`/unlink-account` already takes a
free-form `providerId`).
No Steam Web API key is required for this browser-based flow.
We intentionally do not depend on community Steam packages (e.g.
`better-auth-steam`) or the still-open upstream draft
([better-auth#4877](https://github.com/better-auth/better-auth/pull/4877)).
Steam never returns an email, and we need sign-up that does not ask the
user for one plus first-class account linking; the available options
either require an email at sign-in, lack linking, or are abandoned /
blocked — shipping a small in-tree plugin is the safer auth dependency
for this requirement.
## Test plan
- [x] `pnpm exec vitest run
server/apps/api/src/libs/auth-plugins/steam.test.ts` — 6/6 passing
- [x] `pnpm -F @proj-airi/ui-server-auth exec vitest run` — 32/32
passing
- [x] `pnpm -F @proj-airi/stage-ui exec vitest run
src/libs/steam-auth-client.test.ts
src/composables/use-linked-accounts.test.ts` — 5/5 passing
- [x] `pnpm -F @proj-airi/api-server typecheck`
- [x] `pnpm -F @proj-airi/ui-server-auth typecheck`
- [x] `pnpm -F @proj-airi/stage-ui typecheck`
## Follow-ups
- Desktop Steam ticket sign-in (top of this stack): silent startup
ticket exchange for Steam builds; the server resolves or creates the
AIRI user for the verified SteamID before issuing an OIDC code.
- Steam persona name/avatar via `GetPlayerSummaries` inside the plugin,
if display names beyond `Steam User <id>` are wanted.
