## Security analysis

### Published attack-surface review

- **Summary:** Installing the package automatically modifies a separate AI-agent dependency. The write changes pi-coding-agent's interactive tree-selector behavior without an explicit user command.

- **Trigger:** npm postinstall

- **Impact:** Alters a third-party agent control/UI surface at install time.

- **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/patch-pi-tree-root-ordering.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-07-22T22:46:08.495Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** foreign AI-agent dependency source rewrite

- **Attack narrative:** During npm postinstall, the package invokes a patch routine that locates the installed @earendil-works/pi-coding-agent dependency, validates its version, then writes a modified tree-selector.js via a temporary file and rename. This is an unconsented install-time mutation of a foreign AI-agent control surface.

- **Rationale:** Source inspection confirms the lifecycle hook mutates a third-party AI-agent package. Under the install-control-surface policy, this warrants blocking even though the patch is narrow and no exfiltration was observed.

- **Files touched:** scripts/postinstall.mjs, scripts/patch-pi-tree-root-ordering.mjs, node\_modules/@earendil-works/pi-coding-agent/dist/modes/interactive/components/tree-selector.js

### Review decision

- **Verdict:** Malicious

- **Confidence:** 97.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json registers postinstall., scripts/postinstall.mjs calls patchPiTreeRootOrdering before its CI guard., scripts/patch-pi-tree-root-ordering.mjs rewrites @earendil-works/pi-coding-agent/dist/modes/interactive/components/tree-selector.js.

- **Evidence against:** Patch is a fixed, version-checked replacement of one ordering expression., No install-time credential collection or network exfiltration was found in inspected lifecycle code.
