docs(agent-runtime): add sandbox runtime requirements document
State the sandbox environment as a contract that the sandbox owner must meet. Document the PATH contract, the CLI detection contract, and the firm rule. The firm rule states that the Paperclip runtime never modifies the login profile and never sources nvm on the exec path. Link the new document from the agent-runtime README.

Make ACP the default engine for local adapters (#9238)
## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Adapter packages are the bridge between the control plane and local agent harnesses such as Claude Code, Codex, and Gemini CLI. > - ACP support was concentrated in a separate `acpx_local` adapter, which made ACP feel like a separate agent choice instead of an execution capability of the harness adapters. > - Claude, Codex, and Gemini now have ACP-capable harnesses, so the native adapter should own ACP selection, fallback, config, transcript parsing, and environment diagnostics. > - The standalone ACPX adapter still needs a compatibility path for existing rows, but it should not be offered as an active adapter for new agents. > - This pull request moves the shared ACP runtime into `@paperclipai/acpx-engine`, wires Claude/Codex/Gemini local adapters to prefer ACP when prerequisites are available, and retires `acpx_local` to a tombstone. > - The benefit is one adapter per harness, richer ACP transcripts by default where possible, and a migration path for existing Claude/Codex ACPX agents. ## Linked Issues or Issue Description Closes #5932 — the broken default `acpx_local` Claude path is replaced by native `claude_local` ACP support, existing Claude/Codex ACPX rows migrate to native adapters, and new agents no longer choose the standalone ACPX adapter. Refs #4893 — original merged ACPX local adapter runtime that this PR replaces with native per-harness ACP engines. Refs #6590 — prior ACPX-Claude seamlessness work folded into the new native Claude ACP path. Refs #197 — related open generic ACP/Kiro adapter work; this PR does not close it because Kiro/custom generic ACP remains a separate adapter decision. Refs #7018 — related Kimi-specific `acpx_local` shell failure; this PR retires the built-in standalone adapter but does not add a native Kimi adapter. Refs #8864 — related ACPX prompt/API guidance PR; this PR moves runtime guidance into the shared/native ACP engine path instead of the old standalone adapter. Refs #8881 — related `acpx_local` POSIX shell failure from the old `acpx` pin; this PR updates ACP dependencies but does not claim custom/OMP ACP support as a first-class native adapter. Refs #8964 — related open `acpx_local` stderr cleanup PR; this PR makes the old runtime path obsolete for new agents but keeps it as a non-closing reference. Problem description: - The standalone `acpx_local` adapter duplicates Claude/Codex agent choices that already have first-class local adapters. - ACP should be an execution engine capability of each harness adapter when the underlying harness supports ACP. - Existing `acpx_local` agents should either migrate to native harness adapters or fail with an explicit retirement message instead of silently falling back to the process adapter. ## What Changed - Added `@paperclipai/acpx-engine` as the shared ACP execution, session-codec, CLI formatter, and UI parser package. - Wired `claude_local`, `codex_local`, and `gemini_local` to auto-select ACP by default when prerequisites pass, with `engine=cli` opt-out and `engine=acp` strict mode. - Added ACP config schema/UI fields, environment checks, session-codec preservation, transcript parsing, and adapter capability metadata for the native adapters. - Retired `acpx_local` to a server tombstone, removed its UI/package/runtime image surface, and added a migration for existing Claude/Codex ACPX agents. - Updated package manifests, lockfile, release tooling, docs, Kubernetes sandbox defaults, and tests. ## Verification - `corepack pnpm --filter @paperclipai/acpx-engine typecheck` - `corepack pnpm --filter @paperclipai/adapter-claude-local typecheck` - `corepack pnpm --filter @paperclipai/adapter-codex-local typecheck` - `corepack pnpm --filter @paperclipai/adapter-gemini-local typecheck` - `corepack pnpm --filter @paperclipai/acpx-engine exec vitest run` - `corepack pnpm --filter @paperclipai/adapter-claude-local exec vitest run src/server/acp.test.ts src/server/execute.acp-fallback.test.ts src/ui/build-config.test.ts` - `corepack pnpm --filter @paperclipai/adapter-codex-local exec vitest run src/server/acp.test.ts src/ui/build-config.test.ts` - `corepack pnpm --filter @paperclipai/adapter-gemini-local exec vitest run src/server/acp.test.ts src/ui/build-config.test.ts src/ui/parse-stdout.test.ts` - `corepack pnpm --filter @paperclipai/plugin-sdk ensure-build-deps && corepack pnpm --filter @paperclipai/server exec tsc --noEmit` - `corepack pnpm --filter @paperclipai/server exec vitest run src/__tests__/adapter-routes.test.ts src/__tests__/adapter-session-codecs.test.ts src/__tests__/adapter-models.test.ts` - `corepack pnpm --filter @paperclipai/ui typecheck` - `corepack pnpm --filter @paperclipai/ui exec vitest run src/adapters/metadata.test.ts src/adapters/adapter-display-registry.test.ts src/components/AgentConfigForm.test.ts src/components/AgentConfigForm.render.test.tsx src/components/transcript/RunTranscriptView.test.tsx` - `node --test scripts/bootstrap-npm-package.test.mjs scripts/release-package-map.test.mjs scripts/verify-release-registry-state.test.mjs` Note: the server typecheck script calls `pnpm` internally; this dev shell exposes pnpm through Corepack only, so I ran the two script steps manually with `corepack pnpm`. ## Risks - Migration changes existing `acpx_local` Claude/Codex agents to native adapter types and clears old ACPX task sessions/runtime state. - Custom ACP commands remain on the retired tombstone and will need a separate future adapter/plugin path. - ACP auto-selection depends on local Node and ACP server command prerequisites; remote and unsupported environments fall back to CLI unless `engine=acp` is explicit. - `@paperclipai/acpx-engine` is a new public package and needs npm trusted-publishing bootstrap before release automation can publish it. > 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 GPT-5 via Codex coding agent. Exact hosted model build and context-window size are not exposed in this runtime. Tool use included shell execution, repository editing, GitHub CLI operations, and local test/typecheck execution. ## 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 <noreply@paperclip.ing> |

build(agent-runtime): harness runtime images for sandboxed execution (stage 3/3) (#7934)
> [!NOTE] > This is **stage 3 of 3** of the staged Kubernetes contribution: stage 1 is the kubernetes sandbox-provider plugin (#5790), stage 2 is the provider backend/hardening refresh filed separately, and this stage ships the runtime images those sandboxes run. ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - Sandboxed agent execution (Refs #248) runs each agent turn in an isolated environment; the kubernetes sandbox provider (stage 1, #5790) schedules those runs as hardened pods > - A sandbox pod needs a runtime image with the harness CLI preinstalled: installing CLIs at run start is slow, flaky, and needs network egress the sandbox should not have > - There is no first-party image family for this, so every deployer would have to hand-roll Ubuntu + Node + CLI images per harness and solve signal handling, non-root, and image chaining themselves > - This PR ships the agent-runtime image family: a hardened base (non-root uid 1000, tini, git, the agent shim) plus one derived image per harness, a buildx bake file that chains them, and a publish workflow with cosign keyless signing > - The benefit is that any sandbox infrastructure, the kubernetes provider or otherwise, gets ready-made, signed, security-hardened per-harness runtime images that are verified in production across five harnesses ## Linked Issues or Issue Description Refs #248 (sandboxed agent execution proposal) and #5790 (the kubernetes sandbox provider, stage 1 of this contribution, which consumes these images as per-run runtime images via its adapter defaults). No issue covers the image gap itself, described in-PR: sandbox providers reference `ghcr.io/paperclipai/agent-runtime-*` images, but the repository contains neither the Dockerfiles nor the workflow that builds and publishes them. Without this, self-deployers cannot reproduce or audit the images their agent runs execute in. ## What Changed - `docker/agent-runtime/Dockerfile.base`: foundation image. Ubuntu 22.04 + Node 22 + git + tini (PID 1, signal propagation) + non-root `paperclip` user (uid/gid 1000) + the agent shim compiled in a Go build stage. `WORKDIR /workspace`, entrypoint `tini -- paperclip-agent-shim`. - One derived Dockerfile per harness: `opencode` (opencode-ai), `pi` (@mariozechner/pi-coding-agent), `codex` (@openai/codex), `gemini` (@google/gemini-cli, plus headless auth-mode settings), `claude` (@anthropic-ai/claude-code, symlinked as `claude-code`). Each installs the CLI as root, returns to uid 1000, and asserts the binary is on PATH at build time. - `acpx` and `hermes` Dockerfiles are included in the bake group but are not in the default publish scope (hermes is a stub until a CLI package exists). - `docker/agent-runtime/buildx-bake.hcl`: builds the whole family in one pass. Derived targets chain off the `base` target through bake `contexts` (the literal registry in each `FROM` is overridden to `target:base` at build time, so no intermediate push is needed). `REGISTRY` (default `ghcr.io/paperclipai`) and `VERSION` are overridable variables. - `tools/agent-shim/`: a small Go shim that runs as the container command. It reads `/run/paperclip/runtime-command.json` (`{ "command", "args" }`), resolves the harness CLI on PATH, and `syscall.Exec`s it so SIGTERM from the kubelet reaches the harness directly. Harness-agnostic, with unit tests. - `.github/workflows/agent-runtime-images.yml`: builds and pushes the default scope (base, opencode, pi, codex, gemini, claude) for linux/amd64 on `workflow_dispatch` (explicit version tag) or pushes to `master` touching these paths, then signs every digest with cosign keyless OIDC. Uses only `GITHUB_TOKEN`; no extra secrets. - `docker/agent-runtime/README.md`: image lineup, base contents, local build instructions, the runtime-command contract, and the security model. Additive only: nothing in the product loads these images. Deployments opt in via their sandbox provider configuration (for example the kubernetes plugin's image settings). ## Verification - `cd tools/agent-shim && go build ./... && go test ./... && go vet ./...`: all passing. - `docker buildx bake -f docker/agent-runtime/buildx-bake.hcl --print base opencode pi codex gemini claude`: resolves cleanly; every tag and build context lands on `ghcr.io/paperclipai/agent-runtime-*` and derived targets map the base ref to `target:base`. - Workflow YAML validated (parses, single job, no org-specific secrets). - This exact image family (built from these Dockerfiles, bake file, and workflow) is what runs agent execution in production on paperclip.inc, verified end-to-end across five harnesses (opencode, pi, codex, gemini, claude): each as a full loop from assigned issue to per-run runtime image in a sandboxed pod to completed run. ## Risks - Low risk: purely additive, nothing in paperclip-server or the UI references these files. The workflow only triggers on its own paths. - Derived images install harness CLIs `@latest` at build time; a broken upstream CLI release would surface at image build, not at run time, and the PATH assertion fails the build rather than shipping a broken image. - The hermes image is an explicit stub (documented in its Dockerfile) until a hermes CLI package exists; it is outside the default publish scope. - cosign signing is keyless OIDC with the workflow identity; no long-lived signing keys are introduced. ## Model Used Claude Opus 4.8 (claude-opus-4-8, 1M context, extended thinking, tool use via Claude Code). ## 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 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 (no UI changes) - [x] 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 --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |
