現在の中心仮説
The core problem is no longer making agents look autonomous in a demo. It is making them dependable enough that a human can understand their state, trust the right parts, and interrupt or correct them without paying a coordination tax.
研究概要へ戻る
2026年の見立て
In 2026, the practical frontier is workflow reliability. Agents are becoming useful often enough that standards, identity, evaluation, and escalation design matter more than impressive one-shot completions.
人間中心設計の視点
Oversight fails if review costs more than redoing the work. Good interfaces reduce cognitive load by foregrounding evidence, changes, uncertainty, and consequence before they foreground prose.

なぜ今重要か
The 2025 Stanford AI Index reported that responsible-AI evaluation remains uneven even as documented incidents continue to accumulate. At the same time, NIST's February 2026 AI Agent Standards Initiative, draft benchmark guidance for language-model evaluation, and ongoing ARIA field-testing work all point in the same direction: the next serious step is comparable, operationally meaningful evaluation. My view is that agent progress is now gated less by raw fluency and more by control surfaces such as permissions, observability, interoperability, and human escalation.
現在の優先事項
- Move evaluation from one-shot benchmark wins to repeated-run performance, variance, recovery behavior, and policy adherence.
- Treat traceability as a product feature: tool calls, retrieved evidence, approval checkpoints, and rollback points should be reviewable without exposing unnecessary chain-of-thought.
- Design bounded autonomy with explicit scopes for read, write, execute, and external communication actions.
- Measure trust calibration, not just model confidence, so humans can decide when to rely on the system and when to slow it down.
システム設計の原則
Bounded autonomy
Give agents explicit task scopes, tool budgets, and approval gates instead of vague permission to 'go solve it'.
Inspectable state
Persist the plan, retrieved context, tool outputs, and meaningful diffs so reviewers can reconstruct what happened quickly.
Graceful handoff
Escalation should preserve context and evidence rather than forcing a human to restart the task from scratch.
Comparative evaluation
Compare agents against strong non-agent baselines, mixed-initiative workflows, and failure-handling variants instead of weaker prompts alone.
人間要因とレビュー設計
- Review surfaces should foreground consequences: what changed, what external action is pending, and what evidence supports it.
- Uncertainty needs to be legible at the workflow level, not hidden inside a single confidence score.
- Operator trust should be calibrated with stable conventions, reproducible traces, and reversible actions rather than persuasive language.
- When the system hands work to a person, it should preserve context, partial progress, and rationale so the human can continue without reconstructing the task.
評価アジェンダ
Reliability under repetition
Measure variance across repeated runs, near-miss behavior, and whether recovery steps converge or compound error.
Evidence quality
Score whether retrieved or cited material actually supports the action or conclusion the agent produced.
Oversight efficiency
Track time-to-review, override quality, and whether humans catch the failures that matter.
Policy and safety compliance
Test permission boundaries, escalation behavior, and refusal quality when requests conflict with policy or evidence.
継続している問い
- What is the right granularity for agent permissions in research, coding, and analyst workflows?
- How should we compare autonomous, mixed-initiative, and step-wise systems when human labor is part of the objective?
- Which traces improve reviewer judgment, and which ones only create noise?
- What counts as acceptable failure behavior for an agent allowed to act on external systems?
