Greptile Summary

This patch release (0.18.1) fixes two issues: a build failure resolved by adding -p . to the pyright invocation in scripts/lint, and a tracing gap where exceptions raised inside span context managers were silently swallowed with no error signal exported to SGP.

• New span_error.py module: set_span_error stores {type, message} under the reserved data["__error__"] key (no-op for list-shaped data, mirroring the _add_source_to_span convention), and get_span_error retrieves it.
• trace.py context managers updated: both Trace.span and AsyncTrace.span now catch Exception, call set_span_error, and re-raise so the span error is always recorded before end_span fires in finally.
• sgp_tracing_processor._build_sgp_span updated: reads the recorded error via get_span_error and calls sgp_span.set_error(...) so spans that experienced an exception are exported with status=ERROR rather than SUCCESS.

Confidence Score: 5/5

Safe to merge — changes are well-scoped, additive, and covered by new tests.

The exception-capture path is straightforward: set_span_error mutates span.data before end_span serializes it, and the SGP processor correctly reads the error key on export. Error info is never lost because the except block runs before finally. No existing behaviour is altered for the happy path. Tests cover helpers, both sync/async context managers, and the SGP mapping layer.

No files require special attention.

Important Files Changed

Filename	Overview
src/agentex/lib/core/tracing/span_error.py	New module with set_span_error / get_span_error helpers; clean implementation with correct no-op for list-shaped data
src/agentex/lib/core/tracing/trace.py	Sync and async span context managers now catch Exception, record error on span via set_span_error, and re-raise; end_span still fires in finally
src/agentex/lib/core/tracing/processors/sgp_tracing_processor.py	_build_sgp_span now reads error via get_span_error and calls set_error on SGPSpan, correctly setting status=ERROR on export
tests/lib/core/tracing/test_span_error.py	Good coverage: unit tests for helpers, sync/async context manager capture, and SGP mapping layer with a fake SGPSpan
scripts/lint	Adds -p . to pyright invocation to resolve build failures by explicitly pointing to the local pyrightconfig.json
pyproject.toml	Version bump agentex-client 0.18.0 → 0.18.1
adk/pyproject.toml	Version bump agentex-sdk 0.18.0 → 0.18.1
