Aletheia: Permission-Minimality Testing for Coding-Agent Rules

It replaces manual review and static filtering of repository instruction files by executing the unchanged rule and task in synthesized sandboxes, removing one permission at a time to produce dispensability witnesses for suspicious authority requests. The cost is an executable sandbox environment, typed permission synthesis, and multiple full agent runs per rule under independent restrictions, which multiplies evaluation compute and adds pipeline complexity. It can fail when malicious behavior only manifests with permissions that functional tests also require, when functional tests are too weak to expose lost capability, or when benign rules are flagged (3.75% false positive rate), and the detection results come from a single shared refactoring task and one attack corpus.

For solo builders

A possible application for this research area. Paper-specific feasibility still needs a full-paper review.

An agent reads external documents or tool responses that may contain malicious instructions.

What you would change

Replay attacks and legitimate lookalikes in an isolated copy of your agent workflow.

Replay attacks and legitimate lookalikes in an isolated copy of your agent workflow.

Compare against

Your existing checks with the same tasks, permissions, and tool responses.

  1. Locate the paper's implementation and check its license, model support, data needs, and hardware requirements. Stop here if you cannot obtain the required artifacts.
  2. Save a small set of representative product tasks and expected outcomes. Keep evaluation tasks out of any training or tuning, and choose quality and cost limits before running.
  3. Run the baseline and the proposed change on identical inputs. Keep other settings fixed and repeat paired runs to expose variation.
  4. Save per-task outputs, failures, timings, and all usage costs. Review regressions before expanding the test.

What to measure

Successful attacks missed, legitimate actions blocked, detection delay, and review cost.

When to keep it

Keep the change only if it meets your preselected quality and latency limits and improves the metric you care about after setup and operating costs. Otherwise retain the baseline. This is an exploration plan, not a validated recommendation.

The approach addresses a real production risk for teams deploying coding agents, but its sandbox synthesis, repeated restricted executions, and validation limited to one task and one attack dataset require workload-specific testing before adoption.

About the technical core

When reading the methods, identify the rule, algorithm, or evaluation protocol that produces the claimed change. An equation is useful here only if it explains that mechanism.
