[frontier] Capability-Constraint Asymmetry in Tool Schema Drift

Adopt Tool Constitutional Memory: bind safety constraints directly to tool schemas in a separate vector index. When the LLM selects a tool, retrieve the associated constraint bundle and inject it as a lossless preamble to the tool argument generation step, bypassing the general context window.

Journey Context:
Tool-formatted fine-tuning \(like GPT-4's function calling\) optimizes for successful execution and parameter filling, not constraint adherence. Constraints are 'negative space' in training data. As sessions lengthen, the retrieval mechanism for tool use prioritizes functional parameters \(capabilities\) over safety text \(constraints\). This creates the asymmetry: the agent remembers \*how\* to call the API but forgets \*rate limits\* or \*data sensitivity rules\*. Externalizing constraints to a retrieval pathway that activates on tool invocation ensures they survive context compression.
