From 821573ede850441d5043ecd4860ee70a2a0374b1 Mon Sep 17 00:00:00 2001 From: Nicky Leach Date: Tue, 25 Aug 2026 21:38:27 -0700 Subject: [PATCH] refactor(adapter-utils): extract the shared workspace-restore teardown factory (#12196) ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Agent adapters run workspace restore steps when an ACP run ends. > - Claude, Codex, and Gemini each kept a near-identical teardown closure. > - Duplicate closures require the same defect fix in three files. > - This pull request adds one shared workspace-restore teardown factory and keeps each adapter's message strings. > - The benefit is one tested restore-failure path with the same output and outcome for all three adapters. ## Linked Issues or Issue Description **What existing behavior does this improve?** The Claude, Codex, and Gemini ACP adapters restore the workspace during teardown and report restore failures with an allowlisted message. **Subsystem affected** `packages/adapters/` and `packages/adapter-utils/`. **Current behavior** Each adapter keeps a near-identical closure. The closure logs a start line, restores the workspace, classifies errors, and logs a fixed failure line. **Proposed behavior** A shared `createWorkspaceRestoreTeardown` factory owns the common steps. Each adapter passes its staged runtime, log sink, start line, and failure prefix. **Reason and benefit** The shared factory removes duplicate error handling. One tested implementation now preserves the existing output and outcome for all three adapters. **Breaking changes** None. The refactor preserves the emitted lines and returned outcomes. **Additional context** This pull request contains no public issue reference because no related public issue was found. ## What Changed - Add `createWorkspaceRestoreTeardown` to `packages/adapter-utils`. - Move the shared restore, classify, and allowlisted log flow into the factory. - Update the Claude, Codex, and Gemini ACP adapters to call the factory. - Add a table-driven test for all three message pairs. - Keep one end-to-end restore-failure regression test per adapter. ## Verification - `pnpm --filter @paperclipai/adapter-claude-local typecheck` - `pnpm --filter @paperclipai/adapter-codex-local typecheck` - `pnpm --filter @paperclipai/adapter-gemini-local typecheck` - `npx vitest run packages/adapter-utils/src/workspace-restore-teardown.test.ts` - `npx vitest run packages/adapter-utils/src/workspace-restore-merge.test.ts` - `npx vitest run packages/adapters/claude-local/src/server/acp.test.ts` - `npx vitest run packages/adapters/codex-local/src/server/acp.test.ts` - `npx vitest run packages/adapters/gemini-local/src/server/acp.test.ts` - Continuous integration must pass before merge, except for the known pre-existing failures listed in the handoff. ## Risks Low risk. This change moves shared code without changing behavior. The adapter-specific message strings remain unchanged. ## Model Used OpenAI GPT-5, exact model ID `gpt-5`, tool use and code review assistance. The context window size was not provided by the runtime. ## 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 - [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 --- .../src/workspace-restore-teardown.test.ts | 78 ++++++++++ .../src/workspace-restore-teardown.ts | 51 ++++++ .../adapters/claude-local/src/server/acp.ts | 30 +--- .../codex-local/src/server/acp.test.ts | 147 ++++++++---------- .../adapters/codex-local/src/server/acp.ts | 41 ++--- .../gemini-local/src/server/acp.test.ts | 135 +++++++--------- .../adapters/gemini-local/src/server/acp.ts | 30 +--- 7 files changed, 276 insertions(+), 236 deletions(-) create mode 100644 packages/adapter-utils/src/workspace-restore-teardown.test.ts create mode 100644 packages/adapter-utils/src/workspace-restore-teardown.ts diff --git a/packages/adapter-utils/src/workspace-restore-teardown.test.ts b/packages/adapter-utils/src/workspace-restore-teardown.test.ts new file mode 100644 index 0000000000..664c4dcbff --- /dev/null +++ b/packages/adapter-utils/src/workspace-restore-teardown.test.ts @@ -0,0 +1,78 @@ +import { describe, expect, it } from "vitest"; + +import { createWorkspaceRestoreTeardown } from "./workspace-restore-teardown.js"; + +// One row per adapter's two message strings, taken verbatim from +// claude-local, codex-local, and gemini-local.
