Address review on CopilotKit/CopilotKit#6355:
- Pin `pydantic-ai-slim[ag-ui,openai]==2.22.0` and `ag-ui-protocol==0.1.19`,
matching the starter fleet standard. Open-ended floors would pull a
breaking major on release, and `docker/Dockerfile.agent:16` runs a bare
`uv sync` that would silently re-resolve forward.
- Mirror the specifiers in `uv.lock`'s `requires-dist` so `uv sync --frozen`
at `Dockerfile:42` keeps working. Resolved versions and hashes are
unchanged; `uv lock` is a no-op.
- Construct `StateDeps(ProverbsState())` per request instead of
`dataclasses.replace()`. `replace()` is a shallow copy, so the new deps
point at the same state object; it is only safe today because `StateDeps`
has one field that the adapter rebinds before every run. Any deps class
with a second mutable field would silently share it.
`Agent.to_ag_ui()`, `AGUIApp`, and the `pydantic_ai.ag_ui` shim were removed in
Pydantic AI v2, so the example only ran on v1.
- pin `pydantic-ai-slim[ag-ui,openai]>=2.0.0` and `ag-ui-protocol>=0.1.19`
- import `StateDeps` from `pydantic_ai.ui`
- serve via `AGUIAdapter.dispatch_request` on a Starlette route
- give each request its own `deps` copy so state no longer leaks between threads
Bring the starter agents' Python dependency pins (pyproject.toml + uv.lock
for adk, langgraph-fastapi, langgraph-python, pydantic-ai, strands-python;
requirements.txt + docker override for crewai-crews) in line with the
showcase fleet pin standard.
Replace eslint and prettier with oxlint and oxfmt for faster linting
and formatting across the monorepo. Remove all eslint and prettier
configs, dependencies, and related packages. Add .oxlintrc.json and
.oxfmtrc.json for the new tooling. Update CI workflows and lefthook
hooks accordingly. Reformat codebase with oxfmt.
