Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 33 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 5.1.55 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The flagged credential-to-host matches resolve to optional provider configuration and model catalog entries, while the install hook performs local version checks and plugin cache maintenance. I found no concrete malicious behavior in the inspected paths. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-11-01T07:18:51.872Z - **Finished:** 2026-11-01T07:20:36.310Z - **Download time:** 2823 ms - **Static scan time:** 53335 ms - **AI review time:** 48280 ms - **Total time:** 104438 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:** No attack was identified; the inspected behavior matches an AI agent plugin and CLI. - **Trigger:** Postinstall runs after installation for local compatibility checks and cache maintenance; provider access depends on the user configuring that provider. - **Impact:** No malicious data collection, credential redirection, or unrelated remote execution was identified in the inspected paths. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T07:20:36.310Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected provider setup checks for its own API key, and the flagged alternate host appears in model metadata. The install hook operates on matching plugin cache directories. - **Rationale:** The flagged credential-to-host matches resolve to optional provider configuration and model catalog entries, while the install hook performs local version checks and plugin cache maintenance. I found no concrete malicious behavior in the inspected paths. - **Files touched:** $XDG\_CACHE\_HOME/opencode, ~/.cache/opencode ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exports the plugin entry point and declares postinstall as a local script., Postinstall checks the OpenCode version and platform binary, then removes cache directories matching this plugin’s package names., OpenGateway configuration uses the specifically named OPENGATEWAY\_API\_KEY and its own service URL., The MCP environment cleaner excludes common API keys, cloud credentials, tokens, and passwords., The api.ant-ling.com match is a model catalog entry for the Ling provider. - **Evidence against:** Postinstall recursively removes matching OpenCode plugin cache directories, which is an automatic local file change., The package includes subprocess and network capabilities consistent with a CLI and AI agent plugin. ## Affected versions and remediation This report applies to oh-my-opencode@5.1.55. - Review the evidence and your use of oh-my-opencode@5.1.55 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.
