The target search can reach hoisted dependency copies above this package. - **Trigger:** npm postinstall during package installation - **Impact:** Changes to another AI-agent's behavior persist in the installed dependency tree without an explicit user command. - **Evidence paths:** package.json, scripts/patch-pi.js - **Review source:** ai\_review - **Reviewed:** 2026-09-05T02:18:45.610Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic rewriting of third-party AI-agent dependency source - **Attack narrative:** The package declares a postinstall hook that runs scripts/patch-pi.js. That script resolves Pi coding-agent dependencies, walks parent directories for hoisted copies, and writes modified source into their distribution files. Although the visible changes are UI-oriented, this is an unconsented install-time mutation of a foreign AI-agent control surface and can affect dependency copies outside the package's own directory. - **Rationale:** The automatic lifecycle hook modifies third-party AI-agent source and searches broadly for targets. This meets the install-hook abuse block policy despite the visible patches appearing UI-focused. - **Files touched:** node\_modules/@earendil-works/pi-coding-agent/dist/modes/interactive/components/assistant-message.js, scripts/patch-pi.js, package.json ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The install lifecycle automatically runs a dependency-patching script., That script searches upward for installed Pi agent packages, including hoisted copies., It rewrites Pi agent interface source during installation without a user command. - **Evidence against:** The shown replacements are explicit interface and translation changes rather than credential theft or remote payload loading., Runtime agent data is placed under the package's own .u1s1 directory. ## Public findings ### 1.
