It can remove only previously package-managed retired .codex agent files during upgrade. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-12T02:49:45.851Z - **Finished:** 2026-08-12T02:50:33.227Z - **Download time:** 508 ms - **Static scan time:** 351 ms - **AI review time:** 46516 ms - **Total time:** 47376 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall mutates the installing project with agent workflow templates. It can remove only previously package-managed retired .codex agent files during upgrade. - **Trigger:** npm install of the package without --ignore-scripts - **Impact:** Installs or updates AGENTS.md, docs/ai, and .ttwy-agent workflow controls in the target project. - **Evidence paths:** package.json, scripts/postinstall.cjs, scripts/materialize.cjs, templates/AGENTS.md - **Review source:** ai\_review - **Reviewed:** 2026-08-12T02:50:33.227Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** project-local AI-agent template materialization - **Rationale:** This is an install-time AI-agent control-surface mutation, but its source-aligned purpose is a project-local frontend agent workflow and it uses managed-file conflict protection. The concrete risk merits a warning, not a malicious block. - **Files touched:** AGENTS.md, docs/ai/, .ttwy-agent/, .codex/agents/prototype-intake.toml, .codex/agents/requirement-analyst.toml, .codex/agents/qa-verifier.toml ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall runs project materialization using INIT\_CWD., Installation copies agent workflow templates into the target project., Upgrade can delete previously package-managed .codex agent files. - **Evidence against:** No network, credential collection, or exfiltration code found., Writes are template-based and preserve changed files via .ttwy-agent.new conflicts., Git commands and child processes are explicit workflow/QA actions, not install-time shell execution. ## Public findings ### 1.
