## What does this PR do?
Relaxes the over-strict `partialjson` version constraint in
`sdk-python/pyproject.toml` so the CopilotKit Python SDK can consume
newer compatible `partialjson` releases.
**Change:** `sdk-python/pyproject.toml`
- Before: `partialjson = "^0.0.8"`
- After: `partialjson = ">=0.0.8,<2.0.0"`
## Why
Poetry interprets `^0.0.8` on a `0.0.x` version as `>=0.0.8,<0.0.9`,
which effectively pins the SDK to **exactly** `0.0.8`. This blocks users
from receiving newer, compatible `partialjson` releases (currently
published: `0.0.9`, `0.1.0`, `1.0.0`, `1.1.0`). Relaxing the constraint
lets the SDK pick up fixes and features while still treating the next
major (`2.0.0`) as the breaking-change boundary.
I verified the API the SDK actually uses — `from partialjson.json_parser
import JSONParser` and `JSONParser().parse(...)` — is unchanged across
all published versions up to `1.1.0` (the `JSONParser.__init__` /
`parse` signatures are backward compatible, and the SDK call passes no
arguments). There is no breaking-API risk within the chosen range.
## Test plan
- [x] Validated `sdk-python/pyproject.toml` is well-formed:
`python3 -c "import tomllib,pathlib;
tomllib.load(pathlib.Path('sdk-python/pyproject.toml').open('rb'))"`
- [x] Grepped `sdk-python` for `partialjson` usages — only
`copilotkit/runloop.py` imports/uses it; API is stable across the
allowed range.
- [ ] `poetry lock` / `poetry install` in `sdk-python` resolves a
`partialjson` version within `>=0.0.8,<2.0.0`.
## Changed files
- `sdk-python/pyproject.toml` — single line changed (dependency range
only). No source, example, or lockfile changes.
## Checklist
- [x] I have read the [Contribution
Guide](https://github.com/copilotkit/copilotkit/blob/master/CONTRIBUTING.md)
- [x] No documentation change required (dependency range only)
- [x] "Allow edits by maintainers" is checked

Ships the four sdk-python fixes merged since 0.1.94 (2026-06-04), none of
which are in any published artifact — the newest upload of any kind is the
0.1.95a4 prerelease from 2026-06-19, which predates all of them.

Poetry's ^0.0.8 on a 0.0.x version resolves to >=0.0.8,<0.0.9,
pinning users to exactly 0.0.8 and blocking newer compatible
releases (0.0.9, 0.1.0, 1.0.0, 1.1.0). Relax to >=0.0.8,<2.0.0
so the SDK can pick up fixes/features while still gating on the
next major (2.0.0) as the breaking boundary.
The only SDK usage is partialjson.json_parser.JSONParser().parse(),
which is unchanged across all published versions up to 1.1.0.

0.0.42 ships the single-arg A2UIToolParams API the middleware's a2ui_params
override relies on; pulls ag-ui-a2ui-toolkit 0.0.4 transitively. uv.lock is
unchanged — it locks only the dev/test toolchain, not the runtime deps.
@ag-ui/client 0.0.56 changed runHttpRequest to a thunk signature, breaking
@copilotkit/core's ProxiedCopilotRuntimeAgent. OSS-248 only needs
@ag-ui/langgraph 0.0.41; keep that, revert the unrelated core/client/protocol
'latest' bump. Adopting client 0.0.56 is a separate migration.
ag-ui-langgraph's tool factory now takes one A2UIToolParams object (model
inside) and folds composition_guide into the guidelines bag.
- sdk-js middleware: getA2UITools(params) + type A2UIToolParams import;
pin @ag-ui/langgraph 0.0.40 (the JS release carrying the new API).
- sdk-python middleware: get_a2ui_tools(params) + guarded A2UIToolParams
import; pin ag-ui-langgraph >=0.0.41 (the py release with the new API).
- Update the a2ui injection test skip-reason wording.
The A2UI middleware (@ag-ui/a2ui-middleware) forwards injectA2UITool on
forwardedProps; ag-ui-langgraph surfaces it into agent state at
state["ag-ui"]["inject_a2ui_tool"]. The CopilotKit LangGraph middleware
(py + js) now reads that flag and only injects generate_a2ui when it is
truthy (opt-in), drops the runtime's render_a2ui so the model sees one
A2UI tool, and skips if the agent already defines generate_a2ui. The
catalog only binds surfaces; it is no longer the gate.
Reverts the earlier runtime-forward + context-channel approach.
Deps: ag-ui-langgraph>=0.0.38 (py), @ag-ui/langgraph 0.0.37 (sdk-js),
@ag-ui/a2ui-middleware 0.0.6 + @ag-ui/langgraph 0.0.37 (runtime);
.npmrc min-release-age exclude for @ag-ui/a2ui-middleware. Showcase
langgraph pins bumped to copilotkit==0.1.94a3 / sdk-js 1.59.3-alpha.3 /
@ag-ui/langgraph 0.0.37.
Prebuilt agents get dynamic A2UI with no extra wiring — adding the
middleware is enough. When the frontend registers an A2UI catalog
(surfaced by the runtime into state["ag-ui"].a2ui_schema), the
middleware infers the agent's own model, advertises the generate_a2ui
tool in the model-call hook, and executes it in the tool-call hook.
No catalog → the tool is never advertised.
Covers both @copilotkit/sdk-js and the copilotkit Python SDK. Bumps
the A2UI tool-factory dependency to where get_a2ui_tools ships
(@ag-ui/langgraph 0.0.35, ag-ui-langgraph >=0.0.37).
The new test_emit_tool_call_optional_id.py uses async test methods
decorated with @pytest.mark.asyncio, but pytest-asyncio was missing
from dev dependencies — causing all 11 async tests to fail in CI
across all Python versions (3.10–3.14).

Plain `poetry lock` (no --regenerate) was resolving pydantic-core 2.33.2,
which has no cp314 wheel and forces a Rust source build that fails on
PyO3 0.24 (capped at 3.13). Floor pin steers the resolver to 2.46.3
which ships cp314 wheels, so contributor PRs that bump deps and re-lock
keep CI green on 3.14.
## Summary
- Widens the python dependency from `>=3.10,<3.13` to `>=3.10,<4`
- Adds Python 3.13 classifier to enable installation on newer Python
versions
Closes#3156
Add copilotkit.a2ui module with operation builders and prompt helpers,
fix SystemMessage ID reuse in before_agent to prevent LangGraph duplication,
add Pydantic model_dump serialization for app_context.
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.

The re module was used in _fix_messages_for_bedrock (re.compile) but
never imported, causing NameError at runtime when the middleware is
invoked. Bumps version to 0.1.83.

## Problem
The Poetry caret constraint `^0.115.0` in `sdk-python/pyproject.toml`
resolves to `>=0.115.0,<0.116.0` for 0.x versions (per [PEP 440 / Poetry
docs](https://python-poetry.org/docs/dependency-specification/#caret-requirements)).
This blocks installation alongside any FastAPI release since **0.116.0
(June 2025)**.
Current stable FastAPI is **0.129.0** — 14 minor versions ahead of the
ceiling.
## Impact
- Cannot `pip install copilotkit` in any project using FastAPI >=0.116.0
- Multiple users blocked (see #2771 comments)
- Our production project has **~90 tests bypassed** with
`COPILOTKIT_AVAILABLE = False` guards because of this
## Fix
```diff
- fastapi = "^0.115.0"
+ fastapi = ">=0.115.0,<1.0.0"
```
This allows all current and future 0.x FastAPI releases while still
capping at the upcoming 1.0 major version boundary, which may introduce
breaking changes.
## Testing
- The SDK uses standard FastAPI features (routing, dependency injection,
middleware) that have been stable across all 0.11x–0.12x releases
- No FastAPI APIs used by the SDK were deprecated or removed in
0.116.0–0.129.0
- `ag-ui-langgraph` (also in deps) uses `>=0.115.0` without an upper
bound, so this change aligns the two constraints
## Note on `ag-ui-langgraph`
`ag-ui-langgraph[fastapi]` also depends on FastAPI. Its constraint is
already `>=0.115.0` (no ceiling), so this change to `copilotkit` is the
only fix needed.
Fixes#2771
Tests the two bugs fixed in this PR:
1. Dict raw_event metadata must be read with .get(), not getattr()
2. Filtered events must return None (not ""), and run() strips them
Adds pytest as a dev dependency.
The Poetry caret constraint `^0.115.0` resolves to `>=0.115.0,<0.116.0` for
0.x versions, blocking installation alongside any FastAPI release since 0.116.0
(June 2025). This prevents adoption of the Python SDK in projects using current
FastAPI versions.
Change to `>=0.115.0,<1.0.0` to allow all 0.x releases while still capping
at the upcoming 1.0 major version boundary.
