`tests/examples/` reimplemented each example's logic against `../../src` and never imported `examples/*.ts`. An example could rot or break outright and CI stayed green — and four of the eight had no test at all. Examples do their work at import time via top-level await, so importing one runs it. `tests/examples/run-example.ts` makes that safe under vitest: - `STACKONE_BASE_URL` points the SDK at the MSW mock (toolsets.ts:630 reads it), so an example constructing `new StackOneToolSet()` with no explicit baseUrl still hits the mock rather than production. No example needed changing. - `process.exit` becomes a throw that `runExample` catches and reports as `exitCode`, so an example bailing on missing config is an assertable outcome instead of a torn-down vitest worker. Seven of the eight examples now execute for real. The eighth, claude-agent-sdk-integration, still cannot: `query()` spawns a claude-code subprocess that MSW cannot intercept. Its existing setup-level test is kept and the exclusion is now stated in the file rather than implied. Mock gaps that blocked execution, all of which made the examples exercise nothing: - The three `workday_*` actions every example filters on were absent from the MCP catalog, so the filters matched zero tools. - No Anthropic handler existed at all (mocks/handlers.anthropic.ts). - The OpenAI handlers keyed off prompts none of the examples send; the examples all prompt "List the first 5 employees". - Semantic search (`/actions/search`) was unmocked, so search-tools hit the real network. Added scoped to that test via `server.use` — a global handler pre-empts src/semantic-search.test.ts, which asserts against an unmocked endpoint. Tool-count assertions are exact rather than `> 0`. A `> 0` check cannot fail: `fetchTools` appends tool_feedback *after* filtering, so a filter matching nothing still returns one tool. Verified by mutation — pointing an example at a nonexistent action now fails with `expected 1 to be 4`, where before it passed. defender-config keeps all seven original wire-payload tests, which assert the exact RPC body per defender mode; the four execution tests are added alongside. fetch-tools and tanstack-ai-integration describe examples that do not exist. Relabelled in place rather than moved — the `examples` vitest project globs only `tests/examples/**` and `root` globs only `src/`+`scripts/`, so relocating them would have dropped them from both projects silently. 348 passing, up from 329. The one failure is pre-existing and environmental (`spawn tsc ENOENT`); it fails identically on origin/main.

P3: The mock echoes the fabricated model id `claude-haiku-4-5-20241022`, which is not an Anthropic model (the 20241022 date belongs to claude-3-5-haiku-20241022; Haiku 4.5 is claude-haiku-4-5-20251001).

workday_list_workers, its follow-up still contains that user prompt, so the mock emits the same function call again instead of a final assistant message and the example only stops atstepCountIs(3). Detect a prior tool result/function output and return a terminal response for follow-ups.

Each of these meant the examples exercised nothing:
