The buffer truncation code was slicing at a raw byte offset which could
land in the middle of a multi-byte character (like emojis), causing a
panic. Fixed by using char_indices() to find valid character boundaries.
Also added stop_reason field to CompletionChunk initializers in tests
to complete the stop_reason feature addition.
- Fix byte boundary panic in filter_json.rs line 327
- Add test for multi-byte character handling
- Update test files with missing stop_reason field

openai.rs:
- Use make_text_chunk() for streaming text content
- Use make_final_chunk() for final completion chunk
- Simplify tool_calls conversion logic
embedded.rs:
- Use make_text_chunk() for all 4 streaming text chunks
- Use make_final_chunk() for final completion chunk
- Remove unused CompletionChunk import
Net reduction: 35 lines removed
All tests pass. Behavior unchanged.

databricks.rs:
- Extract ToolCallAccumulator struct to replace opaque (String, String, String) tuple
- Add decode_utf8_streaming() helper for cleaner UTF-8 handling
- Add is_incomplete_json_error() helper for JSON parse error detection
- Add make_final_chunk() helper to reduce duplication
- Add finalize_tool_calls() to convert accumulators to final format
- Refactor parse_streaming_response from ~270 lines to ~100 lines
- Reduce nesting depth from 8+ levels to 4 levels
- Use early returns and let-else for cleaner control flow
file_ops.rs:
- Replace repetitive if-let chains with declarative PATH_CONTENT_KEYS table
- Use match expression instead of nested if-else
- Reduce extract_path_and_content from 44 lines to 20 lines
All tests pass. Behavior unchanged.
New test files:
- crates/g3-cli/tests/cli_integration_test.rs (14 tests)
Blackbox CLI tests: help/version flags, argument validation,
conflicting modes, flock mode requirements
- crates/g3-core/tests/tool_execution_test.rs (20 tests)
Tool call structure tests and unified diff application:
read_file, write_file, str_replace, shell, background_process,
todo, final_output, code_search, take_screenshot
- crates/g3-providers/tests/message_serialization_test.rs (20 tests)
Round-trip serialization tests for Message, MessageRole,
CacheControl, and Tool types. Covers Unicode, special chars,
and edge cases.
All tests follow blackbox/integration-first principles with
documentation of what they protect and intentionally do not assert.
- Remove unused assignment to final_output_called (returns immediately after)
- Mark cache_config field as #[allow(dead_code)] (reserved for future use)
- Mark print_status_line method as #[allow(dead_code)] (reserved for future use)
Converted ~77 info! macro calls to debug! across the codebase to prevent
log messages from interrupting the CLI experience during normal operation.
Users can still see these logs by setting RUST_LOG=debug if needed.

- g3-computer-control

- g3-core
- g3-ensembles

Writes the current context window to logs/current_context_window (uses a symlink to a session ID).
This PR was unfortunately generated by a different LLM and did a ton of superficial reformating, it's actually a fairly small and benign change, but I don't want to roll back everything. Hope that's ok.
This tries to short-circuit multiple round-trips to llm for reading code.
It's a precursor to trying to context engineer tailored to specific tasks.
In initial experiments, it's only marginally faster than regular mode, and burns more tokens.
