## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - Environments define where agent runs execute: local, SSH, or provider sandboxes > - Operators can create and edit environments, but the UI has no way to delete one > - The server already exposes `DELETE /environments/:id` and a delete-blast-radius preflight, but no UI consumes them, and a delete blocked by reusable sandbox leases gives the operator no path forward > - This pull request adds the delete flow to the environment configuration page: a preflight-driven modal that reassigns dependent agents, names the workspaces that hold blocking sandbox leases, and can destroy those sandboxes with explicit consent > - The benefit is that operators can retire stale environments from the UI without database surgery, and dependent agents move to a chosen replacement instead of silently falling back ## Linked Issues or Issue Description Refs #8554 Refs #11124 **Subsystem affected** Environments (server routes, environment runtime service, and the environment settings UI). **Problem or motivation** The environment configuration page has no delete control. The server delete endpoint exists, but nothing in the UI calls it. When reusable sandbox leases block a delete, the 409 error names no owner, so the operator cannot find the blocking workspace. Agents that use the environment as their default lose it silently through the FK `on delete set null`. **Proposed solution** Add a delete button with a confirmation modal on the environment edit page. The modal reads the delete-blast-radius preflight. It offers a dropdown to reassign dependent agents to another environment before the delete. It lists each workspace that holds a blocking reusable sandbox lease, with a link. When those leases are the only blocker, the confirm button destroys the sandboxes inline (`?destroyReusableSandboxLeases=true`) and then deletes. A failed teardown falls back to `pending_cleanup` for the sweep, so no sandbox is orphaned. ## What Changed - `ui/src/pages/CompanyEnvironments.tsx`: delete button on the edit page header, confirmation modal with agent reassignment select, lease-holder list, impact notes, and a consent-labeled destroy-and-delete action - `ui/src/api/environments.ts`: `deleteBlastRadius` and `remove` client methods; `remove` takes an optional `destroyReusableSandboxLeases` flag - `server/src/routes/environments.ts`: `DELETE /environments/:id` accepts `?destroyReusableSandboxLeases=true`; it destroys the environment's reusable sandbox leases first, but only when those leases are the sole delete blocker, then re-checks the blast radius before it deletes - `server/src/services/environment-runtime.ts`: new `destroyReusableSandboxLeasesForEnvironment` — destroys every reusable sandbox lease an environment still owns while the environment config (provider credentials) is still available - `server/src/services/environments.ts`: the delete blast radius now returns `reusableSandboxLeaseHolders` (lease id, workspace, issue) so clients can name what blocks a delete - `packages/shared/src/types/environment.ts`: `EnvironmentDeleteReusableLeaseHolder` type on the blast radius - Tests: route gating for the consent flag (destroy runs, mixed-blocker rejection, surviving-lease rejection), runtime destroy scoped to an environment, blast-radius holder join, and UI tests for the reassignment flow, holder links, and the consent button ## Verification - `npx vitest run server/src/__tests__/environment-routes.test.ts server/src/__tests__/environment-service.test.ts server/src/__tests__/environment-runtime.test.ts ui/src/pages/CompanyEnvironments.test.tsx` - Manual: open Settings → Environments → edit an environment. The trash icon opens the modal. With agents on the environment, pick a reassignment target and confirm; agents move and the environment deletes. With reusable sandbox leases, the modal names the holding workspaces and the confirm button reads "Destroy N sandboxes and delete". ## Risks - The consented path destroys provider sandboxes. It runs only when reusable leases are the sole blocker, so a delete that would still be rejected never destroys anything. A failed teardown routes to `pending_cleanup` and the delete stays blocked until the sweep resolves it. - Agent reassignment issues one PATCH per agent from the client. A mid-sequence failure leaves some agents reassigned; the reassignments are valid on their own and the UI refreshes to the actual state. - Hard blockers (managed local, instance default, pending cleanup) keep the existing 409 behavior and disable the confirm button. ## Model Used - Claude (Anthropic) — Fable 5, model id `claude-fable-5`, extended thinking, agentic tool use via Claude Code CLI. ## 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 - [ ] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge
