Parameter Context Grounding Validator
Software componentSafety & SecuritySafety, Security & Governancearc:ParameterContextGroundingValidator
A pre-execution gate that checks tool parameters for consistency with conversation state, explicit user constraints, resolved temporal references and stable entity references.
Responsibility. Ensures tool parameters reflect the latest conversational intent and constraints.
Also known as: Context Grounding Validator, Consistency checks, Range checks, State consistency verification

Design guidance
- SHOULD flag invocations that contradict established context unless the agent explicitly confirmed a change with the user.
- SHOULD enforce domain-sensible bounds on numeric parameters beyond their syntactic type.
Quantitative guidance
As stated by the sources; verify before use.
- Finance case: 4-layer pipeline caught 94% of parameter errors; parameter accuracy rose 91.7%->97.2% in three months, yielding 99.4% transfer correctness (Ch3.8).

- Quality attributes
- Functional suitability: correctness and validity (ISO/IEC 25010 | NIST AI RMF: valid)
- Risks mitigated
- Stale or contradicted intentConstraint violations (e.g., exceeding stated maximum)Parameters contradicting known facts (e.g., wrong city vs. stated destination)Implausible values (e.g., 0 or 500 hotel guests, suspicious order IDs)State corruption across tool invocations
