AI Agent Sonjomon Refuses Unsafe Production Actions
The author built Sonjomon, an LLM-powered incident-response agent that prioritizes restraint: it decides whether to observe, suggest, stage-for-approval, or act based on model confidence and a risk (blast-radius) registry. The project enforces policy outside the model (deterministic code, ADK hooks, independent verification) and includes 41 tests to prevent destructive actions. Run as 14 live incidents against a deliberately fragile Cloud Run service, Sonjomon diagnosed issues quickly, caught unplanned faults (including misconfigurations and permission gaps), and often refused to change production when evidence or risk warranted. The project was developed over ten days using Gemini 3.5 and Google Cloud tooling; code and a demo are publicly linked.
Practical demonstration of LLM agents for production incident diagnosis and safety mechanisms is relevant to AI operations and reliability, but this is a small-scale solo project rather than a platform-level change.

Key Takeaways & Evidence Grounding
- Project Sonjomon is an LLM-based incident-response agent that gates actions by a tiered autonomy model using confidence and blast-radius.
- The autonomy tiers are OBSERVE, SUGGEST, APPROVE, and ACT; six conservative conditions can only downgrade tiers.
- The implementation includes 41 tests that block destructive actions (one asserts a 96%-confident agent cannot run a destructive action).
- The author ran 14 live incidents against a fragile Cloud Run service; the agent diagnosed faults (including misconfiguration and missing IAM permission) and usually refused to change production.
- The project was built using Gemini 3.5 and Google Cloud tooling (Google ADK, Cloud Run, Pub/Sub, Firestore, Cloud Logging, Cloud Monitoring, Secret Manager).

Majority of AI Agent Tool Calls Lack Protective Guards
An analysis of 16 open-source AI agent repositories — including agent frameworks (CrewAI, PraisonAI) and production applications (Skyvern, Dify, Khoj) — found that 76% of tool calls with real-world side effects had no protective checks (no rate limits, input validation, confirmations, or auth checks). The author published results and an open-source AST-based static scanner called diplomat-agent (Apache 2.0) that detects side-effecting calls and existing guards, and can output a committable toolcalls.yaml inventory. Repo-level findings include Skyvern (76% unguarded), Dify (75%), PraisonAI (89%), and CrewAI (78%). The post explains the methodology, false-positive rate (~15–20%), risks specific to agentic workflows (LLMs decide calls, raising prompt-injection and hallucination hazards), and recommended mitigations: add guards, annotate acknowledged risks, add scans to CI, and maintain an inventory. The scanner is available on GitHub and installable via pip.
Open-source Deterministic Tool Catches Rogue AI Coding Agents
A developer published an open-source tool (v1.0) that detects misbehavior from AI coding agents by using deterministic checks instead of LLM-based analysis. The suite runs as a CI gate and inspects diffs, config files and agent transcripts to flag permission escalations, undeclared network calls, contradictory configs and other drift between an agent's stated intentions and shipped changes. The author argues deterministic rules are reproducible, auditable, fast, local and avoid hallucinations, while probabilistic LLM layers should only be advisory. The project contains a core library, five detectors, a live monitor and a meta-reviewer, and includes a demo “rogue” PR that triggers all detectors. Source code, demo and docs are published on GitHub. Publication date: 2026-05-24.
Agent Security: Prompt Injection, Tool Abuse, Data Leakage
This technical article examines the expanded attack surface of agentic LLM applications and outlines practical defenses against prompt injection, tool-parameter injection, and information leakage. It demonstrates differences between a naive agent and a hardened agent using role-locked system prompts, presents a character-level allowlist and sandboxed eval for tool inputs (calculator example), and proposes a three-layer defense-in-depth pipeline: input validation, a hardened agent layer, and output filtering. The piece includes code snippets for input validators, calculator allowlists, and regex-based output redaction, and provides a design checklist covering system prompt hardening, per-tool validation, allowlist-first policies, and sensitive-pattern filtering. References include the OWASP Top 10 for LLM Applications, LangGraph documentation, and a GitHub demo repository.
