No confirmed malicious chain was found. Installation mutates the pinned Pi dependency's package metadata to rebrand its UI, a non-consensual agent-host lifecycle change. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-10T10:23:03.451Z - **Finished:** 2026-08-10T10:24:04.067Z - **Download time:** 1776 ms - **Static scan time:** 8159 ms - **AI review time:** 50680 ms - **Total time:** 60616 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious chain was found. Installation mutates the pinned Pi dependency's package metadata to rebrand its UI, a non-consensual agent-host lifecycle change. - **Trigger:** npm install executes postinstall. - **Impact:** Changes the installed Pi host's displayed name without modifying its agent-home path. - **Evidence paths:** package.json, scripts/brand-pi.mjs, dist/extension/overcast.js, providers/engines/net/guarded-fetch.sh - **Review source:** ai\_review - **Reviewed:** 2026-08-10T10:24:04.067Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Rewrite dependency piConfig.name for branding. - **Rationale:** The install-time mutation of a third-party AI-agent dependency warrants a warning, but the inspected code shows a bounded cosmetic rebrand rather than concrete malicious behavior. The scanner's command-output-exfiltration claim is unsupported by the source inspected. - **Files touched:** package.json, scripts/brand-pi.mjs, node\_modules/@earendil-works/pi-coding-agent/package.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/brand-pi.mjs on postinstall., scripts/brand-pi.mjs locates and rewrites @earendil-works/pi-coding-agent/package.json., The rewrite sets piConfig.name to "overcast" in a dependency-owned AI-agent package. - **Evidence against:** The postinstall performs no network request, command execution, credential read, or payload loading., The script is idempotent and explicitly preserves pi configDir/session location., dist/extension/overcast.js is an exported Pi extension; its child-process use runs requested media/provider tooling, not command-output exfiltration., Network-capable providers are user-invoked/opt-in and declare their service credentials; guarded-fetch blocks private-address captures. ## Public findings ### 1.
