## Thinking Path > - Paperclip orchestrates AI agents through company-scoped control-plane workflows and extensible runtime integrations. > - Sandbox providers are part of that extension surface because they let agents execute isolated work without baking each provider into the core server. > - Modal already offers managed sandboxes with filesystem, process, timeout, and networking controls that map onto Paperclip's sandbox provider contract. > - The repo did not have a Modal provider plugin, so teams wanting Modal-backed sandboxes had no first-party integration path. > - This pull request adds a standalone `packages/plugins/sandbox-providers/modal` plugin that implements the provider contract, worker entrypoint, docs, and tests. > - The benefit is that Modal can now be installed as a provider plugin without expanding the core control-plane surface area. ## What Changed - Added a new `packages/plugins/sandbox-providers/modal` package with the plugin manifest, worker entrypoint, and exported plugin surface. - Implemented Modal-backed sandbox lifecycle support for creation, command execution, file operations, networking options, termination, and metadata translation. - Added focused Vitest coverage for config validation, env handling, lifecycle flows, networking behavior, and error mapping. - Documented installation, configuration, and usage requirements in the plugin README. - Removed misleading `MODAL_TOKEN_*` fallback behavior so authentication relies on supported Modal credentials only. ## Verification - `pnpm -r typecheck` - `pnpm test:run` - `pnpm build` - `cd packages/plugins/sandbox-providers/modal && pnpm test` ## Risks - Low to medium risk: this is isolated to a new plugin package, but runtime behavior still depends on live Modal account credentials and service-side sandbox semantics. - Modal's current docs target a newer Node baseline than the repo default, so the first live install should confirm credential loading and sandbox startup behavior in a real Modal workspace. - No UI or schema changes are included in this PR. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR. Feature PRs that overlap with planned core work may need to be redirected — check the roadmap first. See `CONTRIBUTING.md`. ## Model Used - OpenAI Codex via Paperclip `codex_local` agent (GPT-5-class Codex coding model; exact backend model ID is not exposed by the runtime), with tool use, shell execution, and code-editing capabilities enabled. ## 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 run tests locally and they pass - [x] I have added or updated tests where applicable - [x] If this change affects the UI, I have included before/after screenshots - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>
