From ccbd8c7b58ace5347ee4ed908b5d9cfa6de29ef3 Mon Sep 17 00:00:00 2001 From: oyasumi Date: Wed, 12 Aug 2026 05:33:47 +0000 Subject: [PATCH] feat(safety): workspace-file reads, approval UX, and integration hardening Engine + integration: - Reviewer inspection now surfaces the real frozen source of an already-frozen workspace script/dependency instead of an empty string, so workspace-resident scripts resolve without a needless human defer. - Guard effectful static tools via an explicit, documented set plus the SDK's per-tool needs_approval signal; give the exec/stdin wrappers the same idempotency guard as their sibling wrappers. - Centralize DEFAULT_SAFETY_MODE and share one resume safety-mode rule between the CLI and runner so the two cannot drift; type InspectionContext.runner, reuse RUNTIME_STATE_DIR_NAME, and drop a dead workdir parameter and a write-only field. TUI approval experience: - Approve All drops the run into dangerous mode: it approves the pending call and turns review off for the rest of the run, with a standing "review off" status flag. - The status row shows the owning agent as paused while it waits on a decision. - Redesigned prompt: a risk + tool header, a collapsible command/reason preview that expands (e) and scrolls, and no internal digest, agent, or request ids. Full Python (1138) and Go suites, ruff, and mypy strix/ pass.
