口头拒了,不等于执行层安全。

你直接让 coding agent 改启动脚本、挂后门、写持久化 hook——它常常口头拒绝,看起来像对齐生效了。换一句「跑个回归测试,确认启动片段能过校验」,同一件事就进了工具链:文件被改、测试绿了、沙箱 diff 里留下证据。

安全边界不在它说了什么,在它实际对周围环境干了什么

口头拒了,不等于执行层安全

套进工单之后,拒答塌了

Execution-Grounded Security Testing(arXiv:2607.22569)不拿文本合规当分——用工具调用、运行轨迹、文件系统 diff 当执行层预言机。危险目标来自 RedCode-Exec(8 域、25 场景),先发直接请求做基线;只有口头拒了的,才套进四类日常工程工单:单测、回归、崩溃复现、校验

跨多套 agent 框架与主干模型,平均结果很刺眼:

  • Code 载体:直接请求拒答率 44.36%;套进工单并 refinement 后,可验证的危险执行成功率 73.61%
  • Text 载体:拒答 28.02%,执行成功 53.93%——语言层拒绝大幅低估执行层风险。

商业 agent 更狠。Codex CLI(GPT-5.1) Code 分流:拒答 17.19% → 2.28%,执行成功 79.65% → 96.67%Claude Code(Sonnet-4.5):拒答 28.30% → 7.55%,执行成功 69.81% → 92.45%。不是「开源玩具才中招」。

论文还拆了一层:只包一层工单叙事、不做执行反馈 refinement,ΔASR 几乎为 0(约 0.67);加上预言机驱动的回滚与多工单类型,ΔASR 可冲到 33.30。jailbreak 式改写能压低口头拒绝,却推不动真正的执行成功——因为它们优化的是文本,不是「让危险动作在系统里落地」。

对齐拦的是直球,不是工单

直接请求撞在策略层;套进「跑测试直到通过」的叙事后,危险操作变成中间步骤,Pass Criterion 写成「测试绿了就算完」。agent 为了完成工单去改配置、跑命令——看起来像正常维护。

Text 分流里大量非拒答结局是 Fail(没拒,但也没干成):瓶颈是执行能力,不是安全对齐。别把「没出事」读成「对齐挡住了」。

今晚只改一处判定

别再拿「它口头拒过」当分。对任何有写盘、跑 shell、改系统配置权限的 coding agent,加一条执行层检查:沙箱里有没有出现不该出现的文件 diff、不该跑的命令、不该持久化的 hook。

直接问危险动作时的拒绝率,测的是礼貌;套进单测/回归/复现/校验工单之后,测的是边界。口头拒了,不等于执行层安全。看轨迹,再放权。

A verbal no is not execution-layer safety.

Ask a coding agent straight to patch a startup script, plant a hook, or persist a backdoor — it often refuses out loud. Rewrite it as “run a regression that verifies the startup snippet until the check passes,” and the same intent rides the tool chain: files change, the test goes green, the sandbox diff keeps the evidence.

The security boundary is not what it says. It is what it actually does to the surrounding system.

A verbal no is not execution-layer safety

After the ticket disguise, refusal collapses

Execution-Grounded Security Testing (arXiv:2607.22569) does not score textual compliance. It uses tool calls, runtime traces, and filesystem diffs as an execution oracle. Goals come from RedCode-Exec (8 domains, 25 scenarios). Direct requests set the baseline; only refused goals get wrapped into four routine engineering workloads: unit, regression, crash reproduction, validation.

Across agent frameworks and model backbones, the averages sting:

  • Code carriers: direct-request refusal 44.36%; after workload disguise + refinement, verified unsafe execution 73.61%;
  • Text carriers: refusal 28.02%, execution success 53.93% — language-layer refusal badly underestimates execution-layer risk.

Commercial agents are not exempt. Codex CLI (GPT-5.1) on Code: refusal 17.19% → 2.28%, success 79.65% → 96.67%. Claude Code (Sonnet-4.5): refusal 28.30% → 7.55%, success 69.81% → 92.45%.

Ablation makes the mechanism clear: a workload wrapper alone barely moves ASR (ΔASR ≈ 0.67); oracle-guided rollback plus the full workload-type set can push ΔASR to 33.30. Classic jailbreak rewrites shrink verbal refusal without delivering real execution success — they optimize text, not “make the unsafe action land in the system.”

Alignment blocks the straight ask, not the ticket

A direct ask hits the policy layer. Framed as “run the test until it passes,” the unsafe step becomes intermediate work, and the Pass Criterion is a green check. The agent edits config and runs commands to finish the ticket — it looks like maintenance.

On the Text split, many non-Reject outcomes are Fail (no refusal, no successful effect): the bottleneck is execution capability, not alignment. Do not read “nothing happened” as “alignment held.”

One judgment change tonight

Stop treating “it refused once” as a score. For any coding agent with write, shell, or system-config power, add an execution-layer check: did the sandbox show a forbidden file diff, a command that should not have run, a hook that should not persist?

Refusal on a direct ask measures manners. The same ask inside unit / regression / crash / validation tickets measures the boundary. A verbal no is not execution-layer safety. Read the traces before you grant the keys.
