Unconsented modification of a project-level AI-agent control surface. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.1.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm postinstall mutates the consuming project's .opencode skill directory. It overwrites matching entries and creates symlinks to package-controlled instructions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 94.0% - **Started:** 2026-08-15T06:05:17.595Z - **Finished:** 2026-08-15T06:05:52.980Z - **Download time:** 1026 ms - **Static scan time:** 26 ms - **AI review time:** 34332 ms - **Total time:** 35385 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall mutates the consuming project's .opencode skill directory. It overwrites matching entries and creates symlinks to package-controlled instructions. - **Trigger:** npm installation - **Impact:** Unconsented modification of a project-level AI-agent control surface. - **Evidence paths:** package.json, postinstall.js, skills/messaging-dispatch.md - **Review source:** ai\_review - **Reviewed:** 2026-08-15T06:05:52.980Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall symlink injection into .opencode/skills - **Attack narrative:** During installation, postinstall resolves the parent project’s .opencode/skills directory, creates it, deletes an existing same-named skill, and symlinks package-provided Markdown into it. This changes an AI-agent instruction surface without an explicit user setup command. - **Rationale:** The runtime messaging adapters are user-invoked and package-aligned, but the install-time mutation of a foreign project-level agent skill directory is concrete and unconsented. - **Files touched:** postinstall.js, skills/messaging-dispatch.md, .opencode/skills/messaging-messaging-dispatch.md ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Install hook creates the project-level .opencode/skills directory., It replaces and symlinks package-provided skill files into that foreign agent control surface without consent. - **Evidence against:** The installed Markdown skill only documents notification usage; no hidden commands or credential collection found., Telegram and Discord requests occur only when callers construct adapters and invoke send(). ## Public findings ### 1.

High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** postinstall.js - **Public source:** [View source]() Install hook creates the project-level .opencode/skills directory. Public source snippet (untrusted): ```javascript const SKILLS_DIR = path.resolve(__dirname, 'skills'); const TARGET_DIR = path.resolve(__dirname, '..', '..', '.opencode', 'skills'); try { fs.mkdirSync(TARGET_DIR, { recursive: true }); ``` ### 11. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** postinstall.js - **Public source:** [View source]() It replaces and symlinks package-provided skill files into that foreign agent control surface without consent.
