Use when executing behavioral verification on agents, skills, and tools against declared contracts, positive properties, negative traps, forbidden side-effects, and bounded timeouts.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Agent Behavioral Testing ## Mandatory Pre-Flight Context Inspection Before running behavioral tests against an agent or skill, inspect these 5 critical parameters: 1. **Contract Invariant Definition**: Define unambiguous positive behavioral properties that MUST appear in the output, and forbidden behaviors that MUST NOT appear. 2. **Sandbox Isolation**: Execute the target agent inside isolated ephemeral worktree environments or mock processes to prevent unintentional host modifications. 3. **Execution Ceiling**: Enforce hard execution timeouts (default 10,000ms) with clean promise races to prevent runaway infinite loops or hanging processes. 4. **Failure Separation**: Differentiate execution crashes (`CRASHED`), timeout exhaustion (`TIMED_OUT`), and contract violations (`FAIL`). 5. **Explicit Verdicts**: Assign one of 5 definitive statuses: `PASS`, `FAIL`, `INCONCLUSIVE`, `BLOCKED`, or `NOT_RUN`. Never allow syntactically valid unexecuted tests to pass. ## Activation Boundaries …

How to install
mdr add harmitx7/tribunal-kit/agent-behavioral-testing@sha256:3c2a4f0df3330a90The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
