## Thinking Path > - Paperclip keeps agent work on a controlled execution plane. > - Sandbox exec wrappers run on the hot path for agent commands. > - The current change removes the explicit `nvm.sh` load step from those wrappers. > - The sandbox image already restores PATH through profile startup. > - This pull request keeps profile sourcing where the wrapper still needs it and drops only the `nvm.sh` load step. > - The result is a smaller command path with the same node and agent CLI resolution. ## Linked Issues or Issue Description No public GitHub issue exists for this change. Problem: The sandbox exec wrappers spent extra time sourcing `nvm.sh` before each command. The sandbox image already restores PATH in `/etc/profile.d/00-restore-env.sh`, so that explicit `nvm.sh` work was redundant. Proposed solution: Remove the `nvm.sh` source step from all six wrappers. Keep the profile sourcing that the provider still needs for PATH setup. Alternatives considered: Keep the existing shell setup and accept the launch cost. That keeps the current behavior, but it leaves the hot path slower than needed. Roadmap alignment: This change keeps the sandbox command path small and predictable. It does not change the adapter contract or the node resolution rules. ## What Changed - Removed `nvm.sh` sourcing from all six sandbox exec wrappers. - Kept profile sourcing where the provider still needs it for PATH setup. - Switched Modal to a non-login shell because the script now sources profiles itself. - Updated wrapper tests to assert that built commands do not source `nvm.sh`. ## Verification - Local TypeScript typecheck passed in each changed package. - Focused provider tests passed for Daytona, E2B, Modal, exe-dev, Cloudflare bridge, and adapter-utils. - One Daytona test failure is pre-existing and unrelated to this change. ## Risks - This change alters shell startup for sandbox exec paths. - A provider that depends on implicit shell setup may need a follow-up. - The current tests cover command shape, but they do not cover every runtime shell path. ## Model Used OpenAI Codex, GPT-5, tool use. ## 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 or instance-local Paperclip issues or links - [x] My branch name describes the change 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>
