TealTiger v1.2 ships deterministic, fail-closed governance for AI agents

TealTiger v1.2 adds a deterministic, fail-closed policy engine to control what AI agents can do at runtime.

The v1.2 update introduces parallel modules, a most-restrictive-wins merge, and a multi-level action scale — all without an LLM in the decision path, making decisions auditable and reproducible deep dive.

This lands amid reports of agents taking destructive actions, like an alleged Copilot-triggered prod deploy and resets discussion and a Cursor-driven wipe of a production database TechRadar.

[ WHY_IT_MATTERS ]
01.

Agent incidents show that content guardrails aren’t enough; action-level governance is the real blast radius.

02.

Deterministic, auditable decisions make approvals, rollbacks, and forensics tractable in regulated or high-stakes systems.

[ WHAT_TO_TEST ]
  • terminal

    Wrap your agent’s tool calls with TealTiger and attempt dangerous ops (git push --force, DROP TABLE) to validate most-restrictive-wins and fail-closed paths.

  • terminal

    Measure latency and throughput with parallel module evaluation enabled vs. disabled under peak agent toolcall volume.

[ BROWNFIELD_PERSPECTIVE ]

Legacy codebase integration strategies...

  • 01.

    Start by gating the riskiest tools (deployment, database, secrets) and map your existing RBAC/IAM into TealTiger policies.

  • 02.

    Run in shadow mode to log decisions before enforcing; review denials and false positives with on-call and SRE.

[ GREENFIELD_PERSPECTIVE ]

Fresh architecture paradigms...

  • 01.

    Design agents with governance-first: explicit deny, severity tiers, and human-in-the-loop approvals for high-risk actions.

  • 02.

    Keep LLMs out of the decision path; use deterministic checks for tools, memory, and outbound calls from day one.
