usability: use cross-platform paths in example docs

[changliu2]

Reporter perspective

As a first-time user on macOS/Linux/WSL, I tried to copy commands from the example docs. Several commands and table entries use Windows backslashes (\), which are not portable in Unix-like shells. Forward slashes work in PowerShell too, so the examples can be made cross-platform without losing Windows support.

Evidence

Backslash paths in customer-facing example docs:

• examples/README.md:20

  assert-eval run --config examples\travel_planner_langgraph\eval_config.yaml

• examples/README.md:32

  assert-eval init --model azure/gpt-5.4-mini --from examples\travel_planner_langgraph\eval_config.yaml

• examples/README.md:42
  • incident_triage_agent\eval_config_baseline.yaml
  • incident_triage_agent\README.md
  • docs\case-study-incident-triage-joint.md
• examples/README.md:47

  assert-eval run --config examples\science_research_agent\eval_config.yaml
  

• examples/incident_triage_agent/README.md:193-194

  assert-eval run --config examples\incident_triage_agent\eval_config_baseline.yaml
  assert-eval run --config examples\incident_triage_agent\eval_config_guarded.yaml

• examples/incident_triage_agent/README.md:200-201

  assert-eval run --config examples\incident_triage_agent\eval_config_naive_prompt.yaml
  assert-eval run --config examples\incident_triage_agent\eval_config_guarded_gepa.yaml

• examples/incident_triage_agent/README.md:217

  python scripts\render_trade_off.py --suite incident-triage-agent-v1

PowerShell-specific activation paths like .\.venv\Scripts\Activate.ps1 are OK when kept in PowerShell-only setup blocks. This issue is about repo-relative paths in commands/tables.

Recommended fix

Use forward slashes in command examples and path literals:

examples/travel_planner_langgraph/eval_config.yaml
examples/incident_triage_agent/eval_config_baseline.yaml
scripts/render_trade_off.py

Then spot-check copy-paste in PowerShell and a Unix shell.
