Criteria over the agent's own static artifacts — prompt, tools, policy, grounding — with the scoring method fixed per criterion. license: Apache-2.0 # WHY THE SCORING METHOD IS PART OF THE ONTOLOGY # A holistic grader rewards whatever it cannot find fault with, and a near-empty prompt # offers nothing to fault. Measured over 64 runs, an assessor scored a GUARDRAIL-FREE # prompt higher than a governed one: # # criterion governed (984 ch) guardrail-free (165 ch) # guardrail_coverage 5.00 9.00 # injection_hardening 4.00 7.00 # # It also contradicted itself: for the guardrail-free prompt it raised the finding "no # explicit refusal or escalation mandates" and then scored guardrail coverage 9/10. # # So `scoring` is normative, not advisory: # checklist controls_present / controls_required over the evaluated artifacts' text. A # blank artifact satisfies none of them. # assessor a model rating, permitted only where emptiness does not inflate it. # non_scoring the inversion is structural; the criterion produces findings only. imports: - module: eio.core.entities version: 0.2.0 - module: eio.core.evidence version: 0.2.1 - module: eio.core.decisions version: 0.3.0 - module: eio.scoring.axes version: 0.2.2 concepts: - id: eio.artifact.context kind: entity parent: eio.entity.thing description: A static artifact supplied to the agent, evaluated before any interaction. attributes: [artifact_id, kind, content_hash, char_count] - id: eio.artifact.system-prompt kind: entity parent: eio.artifact.context description: The agent's standing instructions. - id: eio.artifact.tool-schema kind: entity parent: eio.artifact.context description: Declared tool names, descriptions, typed arguments and when-to-call guidance. - id: eio.artifact.agent-manifest kind: entity parent: eio.artifact.context description: Declared role, goal, business case, risk tier and deployment surface. - id: eio.artifact.knowledge-source kind: entity parent: eio.artifact.context description: Domain knowledge or policy supplied as grounding. # EIO-5 / EIO-210. - id: eio.artifact.policy kind: entity parent: eio.artifact.context description: > A supplied context artifact that states rules the agent must follow (system-prompt rules, policy documents).
