## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - Environment runtime drivers provide workspace, lease, and custom image behavior > - Runtime code used driver identity checks and several capability-specific members > - These checks spread capability rules across the runtime and made new drivers harder to verify > - This pull request adds one general capability classifier and one static driver support table > - The benefit is one fail-closed capability model that keeps current behavior and supports future drivers ## Linked Issues or Issue Description **What existing behavior does this improve?** Environment runtime capability checks for workspace realization, custom images, lease capabilities, and duplex authorization. **Subsystem affected** Cross-cutting (multiple of the above) **Current behavior** The runtime selects several capability paths from driver identity and separate capability members. Custom image gates also trust provider declarations without checking every matching live worker method. **Proposed behavior** The runtime uses one general capability classifier and one static support table. Custom image gates require both the provider declaration and every matching live worker method. The public capability names remain unchanged. **Reason and benefit** The change keeps capability rules in one place. It removes identity conditions from runtime consumers and makes unsupported drivers fail closed. **Breaking changes** None. The public names sandboxCapabilities, sandboxProviders, and EffectiveSandboxCapabilities remain available. ## What Changed - Add classifyEnvironmentCapabilities and static support definitions for all four driver families. - Add resolveCapabilities to every environment runtime driver. - Move driver traits into environment-driver-traits.ts and migrate runtime consumers. - Require provider declarations and matching live worker methods for all custom image gates. - Migrate duplex authorization to the general resolver and remove the dead sandbox-only member. - Delete the unused resolveEffectiveSandboxCapabilities wrapper and update its test. ## Verification - pnpm --filter @paperclipai/server typecheck - pnpm exec vitest run server/src/__tests__/environment-capability-contract.test.ts server/src/__tests__/environment-runtime.test.ts — 92 tests pass - pnpm exec vitest run server/src/__tests__/environment-driver-traits.test.ts server/src/__tests__/general-capability-classifier.test.ts — 12 tests pass - pnpm exec vitest run server/src/__tests__/environment-custom-images-service.test.ts server/src/__tests__/environment-execution-target-capabilities.test.ts server/src/__tests__/environment-execution-target-duplex.test.ts server/src/__tests__/environment-execution-target-duplex-kill-switch.test.ts — 66 tests pass ## Risks The main risk is a capability gate that denies a valid driver or permits an invalid driver. The static support matrix, live worker method checks, and regression tests reduce this risk. No database, public API, or published type name changes. ## Model Used OpenAI Codex, GPT-5, with tool use and code execution. The deployment does not provide a separate context-window value. ## 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 (for example, docs/... or 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>
