Catches the mistakes coding agents repeat before they merge: a pull-request gate with no model call and no API key.
Short answer: Label synthetic/demo data; never mix with live metrics. Demo numbers mixed into live numbers make every report untrue.
Group: Marketing and attribution. Status: stable. Generated from the rule definitions; do not edit by hand.
Playground: https://brevio.pro/tools/agent-guard-playground?rule=R8.2
Honest telemetry attribution: label synthetic/demo data; never mix with live metrics.
Demo numbers mixed into live numbers make every report untrue.
metrics.push(...demoRows, ...liveRows)
metrics.push(...liveRows) // demo rows are labelled and kept apart
A person can silence one finding with brevio-core: ignore R8.2 -- reason on the line or the line above. Without the reason it does not count. An agent cannot silence it: the agent hook and the MCP tools never honour the comment, and a pull request that adds one is reported until a reviewer allows it. Fixing the code is still the better answer.
To change what the rule flags, edit its definition in dev_rules.py or code_rules/__init__.py. That is a code change and is reviewed like one.
