Report #50383

[frontier] Constraints listed separately from capabilities get dropped while capabilities persist

Merge constraints into capability descriptions. Instead of separate sections—'Capabilities: Read CSV files' and 'Constraints: Don't use pandas'—write integrated descriptions: 'Read CSV files using only the csv standard library \(pandas is not available in this environment\)'. Make the constraint part of the capability's activation condition.

Journey Context:
The fundamental asymmetry: capabilities are self-reinforcing \(each use strengthens the activation pattern\) while standalone constraints are self-eroding \(the forbidden path isn't exercised, so the constraint fades\). By merging constraints into capability descriptions, you make the constraint part of the capability's retrieval cue. Every time the agent considers the capability, it re-encounters the constraint. This is more robust than separate constraint lists because it exploits the same reinforcement mechanism that makes capabilities persistent. People commonly structure prompts with a 'Rules' section separate from a 'Tools' section—this is exactly the wrong architecture for long sessions. The merged approach costs more tokens per capability description but dramatically reduces drift.
