Todo 52.1 Benchmark URL Control Characters Plan

Status: in_progress

Goal

Keep malformed benchmark targets inside the configuration error boundary instead of leaking an httpx.InvalidURL during live client construction.

Scope

• Reject ASCII and Unicode characters whose category is control/format, including NUL, CR, LF, and tab.
• Retain the existing HTTP(S), no-userinfo, no-query, and no-fragment requirements.
• Add focused valid/invalid URL regression tests.

Files

• Modify: src/agent_lab/application/benchmark.py
• Modify: tests/test_benchmark_config.py

Verification

• uv run pytest tests/test_benchmark_config.py tests/test_tool_invocation_comparison.py -q
• uv run pytest
• git diff --check
