Running the CLI can also automatically reinstall a newer release after exit and writes its own isolated agent extensions at runtime. - **Trigger:** npm installation; or exiting the CLI after a user-run session with automatic updates enabled - **Impact:** Dependency code can be changed without an explicit patch command, and a future release is installed automatically. - **Evidence paths:** package.json, scripts/patch-pi.js, dist/index.js, dist/agent-setup.js - **Review source:** ai\_review - **Reviewed:** 2026-09-05T03:41:52.422Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall dependency patching and automatic self-update - **Rationale:** Source establishes automatic dependency mutation and an automatic self-update path, but does not establish secret theft, obfuscation, or unconsented mutation of a broad foreign agent control surface. This is a real supply-chain and lifecycle risk, best handled as a warning rather than a block. - **Files touched:** package.json, scripts/patch-pi.js, node\_modules/@earendil-works/pi-coding-agent/dist/\*, node\_modules/@earendil-works/pi-tui/dist/tui-main-screen.js, ~/.u1s1/agent/APPEND\_SYSTEM.md, ~/.u1s1/agent/extensions/u1s1-tools.js - **Network endpoints:** registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** The install lifecycle runs a package script that locates dependency directories by resolution and upward traversal, then rewrites dependency source files., The CLI checks the npm registry and, when automatic updates are enabled, executes a global installation of its own latest release after the user exits., When the CLI is run, it writes prompt and extension code into its agent directory, including tool registration and dynamic imports., Telemetry is enabled unless settings explicitly disable it and posts event batches to the configured gateway. - **Evidence against:** The agent directory is isolated under ~/.u1s1/agent rather than a pre-existing pi installation., The postinstall patch is readable source that targets bundled pi UI behavior; no obfuscated payload or secret collection was found., The package strips its own credential variables before child-process execution., No package self-dependency, install-time network request, or confirmed credential exfiltration was found. ## Public findings ### 1.
