AI Security Review

scanned 3h ago · by lpm-firewall-ai

LPM blocks this version under the AI-agent control-surface policy. The package mutates OpenCode's AI-agent control surface during npm postinstall. Agents are copied to a package-named directory, but skills are installed into the shared global skills directory using generic names.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm install lifecycle postinstall

Impact

Can add or overwrite OpenCode skills that may affect future agent behavior without an explicit user command; uninstall does not remove those skills.

Mechanism

unconsented AI-agent/skill control-surface file copy

Policy narrative

On installation, npm runs scripts/install.js automatically. That script recursively copies package prompts into OpenCode's home configuration, including generic skill directories under ~/.config/opencode/skills/. These files can shape later AI-agent behavior and may replace existing same-named skills. No exfiltration or destructive payload was found, but the install-time mutation of a broad AI-agent control surface is enough to block under policy.

Rationale

Source inspection confirms automatic postinstall writes to OpenCode agent/skill locations, including broad unprefixed skill names, without a separate user setup command. The content is mostly benign and package-aligned, but the lifecycle mutation itself crosses the firewall block boundary for AI-agent control surfaces. Product guard normalized a concrete AI-agent control hijack publish_block to the blockable dangerous-capability shape.

Decision evidence

public snapshot

AI called this Malicious at 82.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for policy block

package.json runs postinstall: node scripts/install.js.
scripts/install.js automatically copies agents to ~/.config/opencode/agents/swe-pro-agents/.
scripts/install.js automatically copies unprefixed skills into shared ~/.config/opencode/skills/.
Skill names like reviewer, testing, planner, repository are generic and may overwrite/control broad OpenCode behavior.
preuninstall removes only ~/.config/opencode/agents/swe-pro-agents, leaving copied skills behind.

Evidence against

No package code found for credential harvesting, exfiltration, eval/vm, child_process, or runtime network calls.
CLI only prints setup/status/version/help and reads opencode.json for status.
Agent/skill prompts appear package-aligned software-engineering roles, not covert data theft instructions.
