Devin Foley	a4ac6ff133	Add sandbox callback bridge for remote environment API access (#4801) ... ## Thinking Path > - Paperclip orchestrates AI agents for zero-human companies > - Agents can run inside sandboxed environments like E2B, which are isolated from the host network > - Sandboxed agents need to call back to the Paperclip API to report progress, post comments, and update issue status > - But sandbox environments cannot reach the Paperclip server directly because they run in isolated network namespaces > - This PR adds a callback bridge that proxies API requests from the sandbox to the Paperclip server, running as a local HTTP server on the host that forwards authenticated requests > - The bridge is started automatically when an adapter launches a sandbox execution, and torn down when the run completes > - The benefit is sandboxed agents can interact with the Paperclip API without requiring network-level access to the host, enabling E2B and similar providers to work end-to-end ## What Changed - Added `sandbox-callback-bridge.ts` in `packages/adapter-utils/` — a lightweight HTTP bridge server that accepts requests from sandbox environments and proxies them to the Paperclip API with authentication - Added request validation and security policy: the bridge only forwards requests to the configured API URL, validates content types, enforces size limits, and rejects non-API paths - Wired the bridge into all remote adapter execute paths (claude, codex, cursor, gemini, pi) — the bridge starts before the agent process and the bridge URL is passed via environment variables - Updated `environment-execution-target.ts` to prefer the explicit API URL from environment lease metadata for sandbox callback routing - Fixed Claude sandbox runtime setup to work with the bridge configuration - Added comprehensive test coverage for bridge request handling, policy enforcement, and sandbox execution integration - Fixed browser bundling — the bridge module is excluded from the frontend bundle via the adapter-utils index export ## Verification - `pnpm test` — all existing and new tests pass, including bridge unit tests and sandbox execution integration tests - `pnpm typecheck` — clean - Manual: configure an E2B environment, run an agent task, verify the agent can post comments and update issue status through the bridge ## Risks - Medium. This is a new network-facing component (HTTP server on localhost). The security policy restricts forwarding to the configured API URL only and validates all requests, but any proxy introduces attack surface. The bridge binds to localhost only and is scoped to the lifetime of a single agent run. ## Model Used Codex GPT 5.4 high via Paperclip. ## 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 - [ ] 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	2026-04-29 16:37:34 -07:00
Devin Foley	4ef969f084	Add E2B sandbox provider plugin (#4452) ... ## Thinking Path > - Paperclip orchestrates AI agents for zero-human companies > - Sandbox environments are part of that execution layer, and the recent core refactor moved provider-specific behavior to a generic plugin seam > - This pull request adds a dedicated `@paperclipai/plugin-e2b` package so E2B can live entirely outside core host code > - Because the feature is still unreleased, the plugin should model third-party packaging directly instead of carrying extra backward-compatibility complexity in core or the workspace lockfile > - This branch therefore makes the E2B provider a standalone publishable package, documents the package-local dev flow, and keeps the publish manifest/runtime dependency story correct > - The benefit is that E2B becomes a true plugin reference implementation that can be installed by package name without reopening core Paperclip code ## What Changed - Added `packages/plugins/paperclip-plugin-e2b` as the E2B sandbox provider plugin package - Implemented config validation, lease acquire/resume/release/destroy handlers, workspace realization, and command execution for E2B sandboxes - Excluded the E2B plugin package from the root workspace so the repo no longer needs `pnpm-lock.yaml` churn for its third-party dependency graph - Added package-local development/install support plus a prepack manifest generator so the published tarball still declares `@paperclipai/plugin-sdk` and `e2b` runtime dependencies - Addressed review feedback by fixing sandbox cleanup on acquire failures, rejecting blank templates, normalizing fractional `timeoutMs`, and always passing the configured template name to the E2B SDK - Updated focused Vitest coverage for config normalization, validation, acquire cleanup, command execution, and lease release behavior - Updated the Dockerfile deps stage to copy the E2B package manifest so the policy check stays in sync ## Verification - `cd packages/plugins/paperclip-plugin-e2b && pnpm install --ignore-workspace --no-lockfile` - `cd packages/plugins/paperclip-plugin-e2b && pnpm build` - `cd packages/plugins/paperclip-plugin-e2b && pnpm --ignore-workspace test` - `cd packages/plugins/paperclip-plugin-e2b && pnpm --ignore-workspace typecheck` - `cd packages/plugins/paperclip-plugin-e2b && npm pack --dry-run` ## Risks - The package now relies on a prepack manifest rewrite so the publish-time dependency list stays correct while the repo-local dev manifest stays workspace-light - The current repo snapshot is still unreleased, so the generated publish manifest points at the repo SDK version until the normal release flow rewrites versions before publish - Real-world E2B environments may still expose edge cases around lifecycle timing or sandbox metadata beyond the mocked unit coverage > 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 `codex_local` - Model ID: `gpt-5.4` - Reasoning effort: `high` - Context window observed in runtime session metadata: `258400` tokens - Capabilities used: terminal tool execution, git, GitHub CLI, and local build/test inspection ## 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 - [ ] 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	2026-04-25 11:01:11 -07:00
