Report #51228

[frontier] Agent remembers it CAN use tools but forgets constraints ON tool use \(rate limits, scope restrictions, approval requirements\)

Co-locate tool capabilities with tool constraints in the same context block—never define what a tool does separately from what it must not do. Use 'constrained capability descriptors' that bundle availability, usage, and restrictions into a single atomic definition.

Journey Context:
Capabilities are reinforced by successful use—every time a tool works, the model's confidence in using it grows. Constraints receive no such reinforcement; they're only maintained by attention. This creates an asymmetric decay where the model becomes increasingly confident in using tools while increasingly forgetting the boundaries on that use. Co-location leverages associative memory: when the model retrieves the capability, it retrieves the constraint simultaneously. Separating them \(e.g., tools in one section, rules in another\) guarantees that capability retrieval doesn't activate constraint retrieval.
