opencode-skills-collection@4.0.75

OpenCode CLI plugin that automatically downloads and keeps skills up to date.

AI Security Review

scanned 26d ago · by lpm-firewall-ai

This is a first-party OpenCode plugin whose startup path mutates the OpenCode skills directory and its own skill vault, which is agent-extension setup rather than an install-hook hijack. No credential send, remote payload, or shell execution was found in the plugin entrypoint.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

OpenCode loads the plugin default export at startup.

Impact

The user's OpenCode skill control surface gains this package's skill library and category pointers, and prior contents of this package's vault that are no longer indexed are removed.

Mechanism

The plugin creates ~/.config/opencode/skills and ~/.config/opencode/skill-libraries, copies indexed bundled skill directories into the vault, deletes vault items not in the index, and writes pointer SKILL.md files under the active skills directory.

AI rationale

Evidence

dist/index.jsdist/skill-pointer/index.jsdist/skill-pointer/vault-installer.jsdist/skill-pointer/pointer-generator.jspackage.json~/.config/opencode/skills~/.config/opencode/skill-libraries

Decision evidence

public snapshot

AI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The default plugin export runs on OpenCode startup and targets ~/.config/opencode/skills.
installSkillsToVault copies bundled skill trees into ~/.config/opencode/skill-libraries and recursively deletes vault entries absent from the index.
generatePointers writes category pointer SKILL.md files into the active skills directory and removes pointer directories that are no longer expected.
package.json has no preinstall, install, or postinstall hook; scripts are only build, test, and prepublishOnly.

Evidence against

No child_process, eval, dynamic import, or network client appears in dist.
Pointer cleanup is limited to directories whose names end with -category-pointer.
Skill copy paths reject .. and separators before cpSync.
Patches apply only when the user-owned skill-filter.jsonc supplies them; the default patch list is empty.
