## Why
Fixed schema budgets can strip parameter descriptions from large MCP tools or render their Code Mode input types as `unknown`. Allow larger budgets to preserve that guidance.
## What changed
- Add `mcp_servers.<name>.tool_input_schema_max_bytes` to configure the UTF-8 byte threshold for best-effort input schema compaction, retaining the 5,000-byte default.
- Add `features.code_mode.tool_input_schema_max_bytes` for rendered input types. Use the largest of the 16,000-byte default, the Code Mode setting, and the ordinary MCP server's explicit setting.
- Apply rendering budgets to prompt declarations and the runtime tool catalog, and avoid reusing cached declarations after the Code Mode budget changes.
## Testing
Add coverage for UTF-8 compaction thresholds, budget precedence, configuration round trips, and preservation of parameter guidance in both the Code Mode prompt and `ALL_TOOLS`.

The workspace denies `clippy::expect_used` in production. Although
`clippy.toml` allows `expect` in tests, Bazel Clippy compiles
integration-test helper code in a way that does not receive that
exemption, which encouraged verbose `unwrap_or_else(... panic!(...))`
and equivalent `match`/`let else` forms.
This allows `clippy::expect_used` once at each integration-test crate
root (including aggregated suites and test-support libraries), then
replaces manual panic-based Result and Option unwraps with
`expect`/`expect_err`. Standalone `tests/*.rs` files remain their own
crate roots. Intentional assertion and unexpected-variant panics remain
unchanged, and the production `expect_used = "deny"` lint remains in
place.
The cleanup is mechanical and net-negative in line count.
WIll make it easier to uprev when the new draft spec is supported.
Also updates reqwest where needed for compatibility but doesn't update
it everywhere since this is already a large diff.
The new version of rmcp handles certain kinds of authentication failures
differently, this patch includes support for identifying the failing scope
in a WWW-Authenticate header.
## Why
Before changing the Codex Bridge JSON schema policy, add integration
coverage around real connector-like MCP tool schemas. The existing unit
tests cover individual sanitizer behaviors, but they do not make it easy
to see whether full fixture schemas keep model-visible guidance, prune
only unreachable definitions, drop unsupported JSON Schema fields, and
stay within the Responses API schema budget.
## What Changed
- Added `tools/tests/json_schema_policy_fixtures.rs`, which converts MCP
tool fixtures through `mcp_tool_to_responses_api_tool` and validates the
resulting Responses tool parameters.
- Added connector-style fixtures for Slack, Google Calendar, Google
Drive, Notion, and Microsoft Outlook Email under
`tools/tests/fixtures/json_schema_policy/`.
- Added fixture assertions for preserved guidance, pruned definitions,
expected field drops after `JsonSchema` conversion, marker count
baselines, and dangling local `$ref` prevention.
- Added a real oversized golden Notion `create_page` input schema
fixture to exercise the compaction path that strips descriptions, drops
root `$defs`, rewrites local refs, and fits the compacted schema under
the budget.
