Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 4.0.33 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection confirms a guarded first-party OpenCode extension setup that mutates agent skill configuration at startup. This warrants a warning under the lifecycle policy, but there is no concrete malicious chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-08-16T00:39:06.513Z - **Finished:** 2026-08-16T00:40:20.201Z - **Download time:** 6059 ms - **Static scan time:** 3864 ms - **AI review time:** 63764 ms - **Total time:** 73688 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The package is an OpenCode plugin that automatically provisions a bundled skill library and pointers at OpenCode startup. This is a first-party agent-extension lifecycle mutation, not an npm install-time attack. - **Trigger:** OpenCode loads the installed plugin at startup. - **Impact:** Bundled agent instructions become available to OpenCode; package updates can replace its managed vault and pointer content. - **Evidence paths:** package.json, dist/index.js, dist/skill-pointer/index.js, dist/skill-pointer/vault-installer.js, dist/skill-pointer/pointer-generator.js, bundled-skills/playwright-skill/run.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T00:40:20.201Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Copies bundled skills into the OpenCode vault and generates category-pointer SKILL.md files. - **Rationale:** Source inspection confirms a guarded first-party OpenCode extension setup that mutates agent skill configuration at startup. This warrants a warning under the lifecycle policy, but there is no concrete malicious chain. - **Files touched:** bundled-skills, skills\_index.json, ~/.config/opencode/skill-libraries, ~/.config/opencode/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** On OpenCode startup, the plugin installs its bundled skill collection into OpenCode configuration and creates active skill pointers., Its update path recursively deletes stale package-managed vault entries and rewrites package-owned pointer skills., A bundled, user-invoked Playwright helper installs dependencies and executes supplied JavaScript. - **Evidence against:** package.json has no preinstall, install, or postinstall hook; prepublishOnly is publish-time only., No runtime network client or credential collection exists in dist/; the HF token request is a separately invoked example., The PDF is a normal PDF and the tarball lists source-component files; neither establishes a staged payload. ## Affected versions and remediation This report applies to opencode-skills-collection@4.0.33. - Review the evidence and your use of opencode-skills-collection@4.0.33 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
