Month: 2025-10 — UKGovernmentBEIS/inspect_ai focused on strengthening documentation quality for sandboxing. Delivered a targeted Sandbox Documentation Accuracy Fix that corrects a typo in the default_polling_interval description and improves the sandbox docs table formatting to better reflect initialization and cleanup processes. This work improves developer onboarding, reduces potential confusion, and lowers support overhead by ensuring docs align with runtime behavior. The change is documentation-focused with clear traceability to commit and PR (commit 9f3a6dc80014bac1d622446a6af8d03b05541657; PR #2582). Demonstrated competencies in documentation standards, Markdown formatting, and version-control hygiene.
