AI Coding Instructions

Follow the root AGENTS.md and the nearest nested AGENTS.md for the files you edit.

Use the root completion and authorization boundaries; consult docs/internals/contributing.md for task-specific testing and failure diagnosis. Continue scoped local implementation, deterministic checks, and fixes without asking at each step.

• Add same-area tests with the production change as defined by scripts/pr/change-policy.ts. Preserve or improve the coverage ratchet and meet the changed-line coverage threshold; maintainer overrides remain explicit decisions.
• Use E2E or desktop UI smoke when unit tests cannot prove a user-visible cross-boundary flow. Ad-hoc browser automation uses ego-browser; committed smoke scripts retain their own runner.
• Provider/auth/runtime-env/model-window/proxy changes require offline bun run check:provider-contract when selected by check:impact; desktop chat/WebSocket/session changes likewise use check:chat-contract.
• Live smoke is trusted-maintainer evidence only and requires explicit authorization. Required tests use isolated fixtures and no saved credentials.
• Follow the root verification policy once for the final diff. In the handoff, include changed files, tests added, commands actually run with pass/fail counts when available, checks not run, evidence paths when generated, and remaining risk.
