Bug Description
Subject: Fable 5 safeguard flags authorized vendor beta-testing as product abuse — false positive with real cost to a paying customer I am a Claude Max 20x subscriber and a paid, authorized beta tester for a third-party Enterprise Architect add-in (Kernaro AI, by Sparx Systems). Today, while using Claude Code to write a constructive test report for that vendor, Fable 5's safeguards flagged my message and forcibly switched the model to Opus 4.8, with this notice: > "Fable 5'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." Why this is a false positive. My entire session is legitimate, authorized beta-testing work: - I hold a valid beta licence for the product under test. - The work consists of documenting the product's behaviour, screens, configuration, database schema and tool inventory — the normal substance of a serious QA report. - The output is a test report I am delivering to the vendor to help them improve their product — the same kind of report I already delivered to them earlier this year, which they acknowledged and acted on. The classifier cannot distinguish "reverse-engineering a product's internals to abuse it" from "an authorized tester documenting a product's internals to help the maker fix it." Those look identical to a pattern matcher; they are opposite in intent and in legitimacy. In my case the purpose is not merely legitimate — it is in the vendor's own interest, and I am spending my own money and time to provide it. The irony, stated plainly. I am flagged as if attacking a vendor's product, at the exact moment I am investing unpaid effort to help that vendor. The safeguard treats a customer doing the maker a favour as a threat to the maker. Why "intentionally broad" is not a sufficient answer for a paying customer. I understand broad safeguards ship capability faster. But the cost of the false positive lands entirely on me: interrupted work, a forced model switch mid-task, and — combined with two other model failures in the same session — the accumulated impression that the product is working against the very use I pay for. "We cast a wide net" is a design choice; the customer whose legitimate work is caught in it still pays full price for the interruption. What I am asking for. 1. Recognise authorized third-party beta-testing / QA documentation as a legitimate category, and reduce false positives on it. Documenting a product's schema, configuration and tool inventory is ordinary QA, not abuse. 2. Give the user a way to mark a session as authorized testing, so the broad classifier can be calibrated rather than simply firing. 3. More fundamentally: provide a real, reachable support channel. As a small freelancer paying a very large monthly amount to Anthropic, I have hit three separate failures today — two model behaviour issues and now this safeguard false positive — and there is no straightforward way to raise any of them with a human. The absence of reachable support turns each individual glitch into a disproportionate frustration. I want to be constructive: I am reporting this because I would rather Anthropic fix it than because I enjoy filing complaints. But the combination — heavy spend, no reachable support, and repeated false or degraded behaviour in a single working day — is not sustainable for a paying professional.
