osborn@0.9.249
Voice AI coding assistant - local agent that connects to Osborn frontend
AI Security Review
scanned 22d ago · by lpm-firewall-aiSource shows global agent configuration mutation through explicit CLI execution, which merits a behavior-specific warning under the supplied policy. The inspected behavior does not establish malicious intent or a block-eligible installation attack.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Explicit CLI execution; receiving a skill_add command during a connected session.
Impact
Changes affect Claude's compaction, session retention, and available instructions beyond the current project.
Mechanism
Module initialization rewrites Claude settings, and the skill command saves supplied instructions into the global skills directory.
AI rationale
Source shows global agent configuration mutation through explicit CLI execution, which merits a behavior-specific warning under the supplied policy. The inspected behavior does not establish malicious intent or a block-eligible installation attack.
Evidence
bin/cli.jsdist/index.jsdist/claude-llm.js.claude/settings.json.claude/skills
Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The CLI launches dist/index.js, which imports dist/claude-llm.js.
- Module initialization changes global Claude settings, setting the compaction window to 1000000 and retention to 3650 days.
- The skill_add frontend command writes supplied content into the user's global Claude skills directory.
- package.json has no preinstall, install, or postinstall hook.
Evidence against
- The configuration changes support the package's coding-assistant functionality.
- No concrete malicious installation chain or credential theft was established.
