Stacktrace · runtime detection
What Stacktrace detects and measures for Claude Code, Devin and Codex today, and what cannot be supported for each agent and why. Codex is read by OpenAIDR 0.7.0's Codex reader.
† waits on a field not yet confirmed in a real session. cost-personal-anomaly runs in Fleet on uploaded usage, so it works wherever the usage upload does. Codex grades are the built code's, verified end to end over synthetic Codex homes.
Claude Code has no detection gaps. The Claude Code plugin and the playground are Claude-only by scope, not by a missing record.
Source of truth: docs/agent-support.md in stacktrace-ai/stacktrace. The Codex evidence is Codex CLI 0.163.0 run against a mock model and its source at rust-v0.163.0, and a live run on gpt-6.1-sol against a local Fleet. The reader design is docs/specs/codex.md in open-agent-security/openaidr.
