A package installation can change local AI-agent behavior and remove an existing skill directory. - **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:** 2.6.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically replaces agent skill directories for Codex and Claude. This can alter the instructions those agents load without a separate setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-09-04T08:14:14.024Z - **Finished:** 2026-09-04T08:15:05.354Z - **Download time:** 260 ms - **Static scan time:** 971 ms - **AI review time:** 50097 ms - **Total time:** 51330 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically replaces agent skill directories for Codex and Claude. This can alter the instructions those agents load without a separate setup command. - **Trigger:** npm installation, through the postinstall lifecycle hook. - **Impact:** A package installation can change local AI-agent behavior and remove an existing skill directory. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/setup.js, dist/skill-update.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T08:15:05.354Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic recursive replacement of AI-agent skill directories. - **Attack narrative:** npm runs scripts/postinstall.mjs automatically. It imports dist/setup.js, which resolves Codex and Claude configuration homes, recursively removes each recess-cli skill directory, and copies a package-controlled skill into it. The explicit setup path additionally fetches a skill bundle from the configured Recess API and writes it to the same directories. This is unconsented postinstall mutation of broad AI-agent control surfaces. - **Rationale:** The package has a concrete automatic lifecycle path that overwrites both Codex and Claude skill directories. Under the install-control-surface policy, this is malicious install-hook abuse even though the code has path checks and no secret exfiltration was found. - **Files touched:** $CODEX\_HOME/skills/recess-cli, $CLAUDE\_CONFIG\_DIR/skills/recess-cli, $CODEX\_HOME/skills/recess-admin, $CLAUDE\_CONFIG\_DIR/skills/recess-admin - **Network endpoints:** https://api.recess.gg/auth/admin-cli/skill/ ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The npm postinstall hook automatically imports and runs the skill installer., The installer targets both Codex and Claude user skill directories., Installation recursively deletes the existing skill and copies the package-supplied replacement without an explicit user command., A runtime setup command can also download server-provided Markdown and write it into those same agent skill directories. - **Evidence against:** The postinstall script skips source checkouts and suppresses failures., The remote bundle updater restricts received filenames to Markdown and checks destination containment., No credential harvesting or unrelated network exfiltration was found in the inspected lifecycle path. ## Public findings ### 1.
