## Thinking Path > - Paperclip manages AI agents and their execution environments. > - Managed Git helpers run next to those agents. > - Some environments keep their Node interpreter outside the agent PATH. > - The current generator always emits an env-based Node shebang. > - This pull request lets the environment select an absolute interpreter path. > - Existing callers keep the same default behavior. ## Linked Issues or Issue Description Refs #18212. **What happened?** A managed helper can fail when Node exists only as a private runtime binary. The caller must currently alter generated source or expose that runtime through PATH. **Expected behavior** The source generator accepts an optional interpreter path. The environment can keep its own runtime private. **Steps to reproduce** Generate a helper in an environment whose PATH has no usable Node. Run a local Git command through that helper. The env-based shebang cannot select the private interpreter. ## What Changed - Add optional `interpreterPath` to `githubLauncherSource`. - Preserve `/usr/bin/env node` when the option is absent. - Reject relative paths, whitespace and NUL bytes. - Document the option and test actual execution with an unusable Node on PATH. ## Verification - The affected adapter-utils package typecheck passed. - All 26 tests in `packages/adapter-utils/src/github-launcher.test.ts` passed. - The new test runs a generated helper as a child process. It proves that the selected interpreter bypasses a failing PATH-selected Node and that the helper body stays unchanged. - Invalid-path tests passed. Existing broker and local-Git tests passed. - Full checks run in GitHub CI per the user's request. No full local suite was run. ## Risks The option changes only the shebang. Callers own interpreter installation and immutability. Default behavior, PATH, credentials and permission policy stay unchanged. No schema or workflow changes. ## Model Used OpenAI GPT-6.1 Sol (`gpt-6.1-sol`), high reasoning, with source inspection and targeted execution. The host does not expose an exact context-window size. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge Co-authored-by: Paperclip <noreply@paperclip.ing>
