## 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) | — |

### Notes / non-goals
- Fallout-only updates for the xsai beta.8 API rename: `textStream`,
`inputTokens` / `outputTokens` / `totalTokens` in component-calling /
telegram / satori.
