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:** 3.21.0 - **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. The active postinstall hook automatically replaces package-owned skills in user-level agent directories. This warrants a warning for agent extension lifecycle risk, while the inspected skill and setup code do not establish concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-14T23:00:44.686Z - **Finished:** 2026-10-14T23:01:31.047Z - **Download time:** 510 ms - **Static scan time:** 1502 ms - **AI review time:** 44347 ms - **Total time:** 46361 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 npm postinstall hook installs the package's bundled skill into the user's Codex and Claude skill directories. This changes what those agents can read after installation, but inspected source does not show a malicious skill payload. - **Trigger:** Installing the package through npm when the packaged setup module is present. - **Impact:** Agents may use the newly installed Recess command guidance in later sessions; the automatic global skill change is an agent extension lifecycle risk. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/setup.js, skill/recess-cli/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-10-14T23:01:31.047Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook calls installSkill, which replaces the recess-cli skill directories with the bundled skill and removes a superseded skill directory. - **Rationale:** The active postinstall hook automatically replaces package-owned skills in user-level agent directories. This warrants a warning for agent extension lifecycle risk, while the inspected skill and setup code do not establish concrete malicious behavior. - **Files touched:** ~/.codex/skills/recess-cli, ~/.claude/skills/recess-cli, skill/recess-cli ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json registers a postinstall hook that runs scripts/postinstall.mjs., On a packaged install, the hook calls installSkill when dist/setup.js exists., installSkill targets the user's Codex and Claude skill directories, replaces the recess-cli skill there with the bundled copy, and removes a superseded skill directory., The bundled skill routes agents to Recess CLI commands and describes its authentication and confirmation contracts., The apps init command separately writes AGENTS.md into the selected app directory. - **Evidence against:** The automatic setup installs this package's own skill; inspected code does not establish a malicious payload or broader agent configuration change., Fetching an additional server skill copy occurs in the CLI setup path, not in the postinstall hook. ## Affected versions and remediation This report applies to recess-cli@3.21.0. - Review the evidence and your use of recess-cli@3.21.0 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.
