The OAuth helper only names a local encrypted token file under the user home .claude directory and does not send those tokens. Install and runtime behavior is a Termux compatibility wrapper around the official Claude Code CLI. - **Trigger:** npm postinstall, or a user launching the claude or claude-termux bin. - **Impact:** The changes stay on the local machine and in this package's dependency tree. No credential send, remote payload execution, or agent settings rewrite was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-26T11:35:35.568Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** On Termux, postinstall places ripgrep and sharp-wasm32 beside the installed Claude Code package and creates an empty home .claude directory. The bin then applies local require and spawn shims and may update this package from the npm registry. - **Rationale:** The package is a Termux wrapper for @anthropic-ai/claude-code: postinstall downloads fixed ripgrep and sharp artifacts only on Termux, and the OAuth path is a local file with no send sink. Auto-update and empty ~/.claude directories are user-launched or directory-only and do not rewrite agent control files. ### Review decision - **Verdict:** Clean - **Confidence:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Final policy explanation:** The AI recommended clean. Static policy retained a warning. A high or critical static finding has no usable source path. These conditions do not mean that the AI confirmed malicious behavior. - **Evidence for AI clean decision:** package.json exposes claude and claude-termux bins, a postinstall script, and a dependency on @anthropic-ai/claude-code rather than itself., OAuth storage names a local ~/.claude/.oauth-tokens.enc file; store and read stay on disk, and apply only publishes those helpers on a global when Termux is detected., Postinstall creates an empty ~/.claude directory only after a local Claude Code path is found and only when the process looks like Termux., CLI auto-update queries the npm registry for this same package and skips itself when CLAUDE\_NO\_AUTO\_UPDATE=1 or --no-auto-update is set., The Sharp patch redirects require('sharp') to the WASM build only on Android or nonstandard arm64., scripts/verify-install.js is the npm test script and only runs local command checks., The ripgrep patch, on Termux, redirects spawn of a missing android ripgrep path to the system rg binary. - **Evidence against:** Postinstall can curl a fixed ripgrep release and a fixed sharp-wasm32 tarball, then extract them with tar, when Termux is detected., Running the claude bin can npm install -g a newer release of this same package unless auto-update is disabled., On Termux the wrapper creates empty ~/.claude, commands, and agents directories and points CLAUDE\_CONFIG\_DIR there. ## Affected versions and remediation This report applies to claude-code-termux@1.0.180. - Review the evidence and your use of claude-code-termux@1.0.180 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
