I appreciate you sharing this, but I need to clarify: this appears to be about Fable (a programming language) and vehicle ECU parameters, which is unrelated to Claude Code (Anthropic's CLI tool for coding with Claude). If you're experiencing an issue with

Description

**Bug Description**
I uploaded my vehicle's ECU database to decode its PIDs. I have been using Fable 5.1 for this purpose with success. However, the last time I uploaded this data, a safeguard flag was triggered. I had been using Fable 5.0 for this purpose for months without any issues.

**Environment Info**
- Platform: linux
- Terminal: ghostty
- Version: 2.1.263
- Feedback ID: 205e0673-5d03-4280-b77e-ab7abb2c3f76

**Errors**
Fable 5.1's safeguards flagged this message. Our intentionally broad safeguards allow us to deliver more capabilities faster, but can sometimes flag legitimate coding, cybersecurity, and biology tasks. Switched to Opus 4.8. Send feedback with /feedback or learn more

Details: `[cyber]`
⎿ Tip: You can configure model switch behavior in /config

Research direction

The report names no repository file or test and explicitly says the behavior concerns Fable and vehicle ECU data rather than Claude Code. Start by checking the /feedback context and Feedback ID 205e0673-5d03-4280-b77e-ab7abb2c3f76 against Claude Code's scope; the issue is actionable only if it reproduces in the CLI. Done means a concrete Claude Code safeguard failure with reproducible input and expected behavior.
