SkillShield: Prompt-Space Security Skills for LLM Coding Agents

A coding agent edits files and executes shell commands with its developer's privileges, allowing malicious requests to translate directly into harmful actions or functional malware. Existing defenses have complementary limitations: weight-level alignment is unavailable to API-only deployers,...

Aegis aegis-v0.13.0-alpha

AEGIS OS-level oversight for AI coding agents Open-source monitor that shows what AI coding agents actually do on your machine — at the OS level, no agent hooks required. AEGIS sees every AI agent on your machine — even ones that don't cooperate. It is an independent, OS-level observer that watch...

SkillBloat: Token Amplification Attacks Via Skill Injection in LLM Coding Agents

Agent skills extend coding agents with task-specific instructions, scripts, and resources, but they also create a trusted instruction channel that can be abused beyond conventional security attacks. This paper studies token amplification through skill injection: an economic resource-abuse threat ...

Permission Denied: Policy-Graded Evaluation of Coding Agents in Hardened Environments

Coding agents increasingly run inside organizations whose security controls scoped credentials, restricted egress, read-only filesystems, non-root execution constrain them like any other software. Existing benchmarks, however, evaluate agents almost exclusively in permissive sandboxes, so it is...

fence v0.1.65

Fence wraps commands in a sandbox that blocks network access by default and restricts filesystem operations based on configurable rules. It's most useful for running semi-trusted code package installs, build scripts, CI jobs, unfamiliar repos with controlled side effects, and it can also compleme...
