Devin FoleyandPaperclip c5ca29dbef fix(claude): prepare compatible sandbox runtimes during onboarding (#17259)
## Thinking Path

> - Paperclip connects agent accounts and prepares their execution
environments.
> - A managed sandbox image can outlive the model defaults shipped by
the app.
> - Claude setup skipped installation whenever a CLI was already on
PATH.
> - The selected model then failed its minimum-version check after
sign-in succeeded.
> - This pull request prepares a compatible private CLI before testing
or running it.
> - Cloud onboarding also stops asking customers to run inaccessible
shell commands.

## Linked Issues or Issue Description

**What happened?**

A new managed Cloud stack completed Claude subscription sign-in. Its
environment test then failed because the snapshot contained Claude Code
2.1.263, while the selected `claude-opus-5-5` model requires 2.1.280.
The screen displayed Manual debug commands that a hosted customer cannot
run.

**Expected behavior**

Paperclip prepares its managed runtime before testing the selected
account. A stale image CLI does not require the customer to upgrade a
server package. Failed preparation still blocks hiring. Cloud does not
display manual shell debugging.

**Steps to reproduce**

1. Start a managed sandbox with Claude Code 2.1.263 on PATH.
2. Connect a Claude subscription and select `claude-opus-5-5` on the CLI
lane.
3. Connect the agent. Installation is skipped because the command
exists, then the version gate blocks the hello test.

**Paperclip version or commit**

Source baseline: `6204239cfc8c3be79fc185cf3f468ebaa0ab1e3e`.

**Deployment mode**

Authenticated managed Cloud with a Daytona named snapshot. The
correction also applies to the default CLI in other managed sandbox
transports.

Related work: Refs #14993 sets model/runtime requirements; Refs #15993
changes native defaults on qualified targets. Neither prepares an
outdated default sandbox CLI on this path. Searches found no open
duplicate.

## What Changed

- Check the actual default CLI against the selected model's existing
minimum version.
- When a sandbox's default command is outdated, install the exact
required npm package into a private versioned workspace prefix. Reuse a
compatible private installation. Keep the image's global CLI intact.
- Verify the private executable and use that same command for the
account hello test and normal CLI runs, with matching command metadata.
Probe effort support after preparing that executable so the chosen
effort is retained. Keep the model, account, engine and permissions
unchanged.
- Return safe preparation checks to environment tests and normal run
logs, distinguishing installation failure causes without returning raw
installer output or credential-bearing URLs.
- Exclude provider and Paperclip credentials from the installer
environment. Preserve the existing failing version gate if installation
or verification cannot succeed. Local, SSH and explicit custom commands
remain operator-managed.
- Hide Manual debug and legacy operator check hints on Cloud and while
deployment metadata is unknown; preserve check messages and details.
Retain self-hosted help and the detailed failed checks. Cloud copy asks
for a retry instead of asking the customer to repair the environment.
- Add subprocess-backed runtime controls, an account-probe regression
and mounted Cloud/self-hosted wizard controls. Update development
guidance and the affected capability maps.

## Verification

- Passed all Claude source suites and the server Claude execution suite
on head `c941ae44c22d8dafec0df033a129e39ce4ebd966`: **412 passed**, one
existing opt-in test skipped. These include the new command/effort
ordering, safe installer diagnostics, environment forwarding and run-log
regressions.
- On final head `0ecae0e9304f495a57524158b3700b8e9bc21cb8`, passed **208
tests** across all 174 mounted onboarding wizard tests and 34 Claude
execution tests. The failure fixture includes the real command-bearing
hint, and execution asserts both metadata command fields agree.
- Passed `pnpm -r typecheck`, `pnpm build`, `pnpm check:token-gates`,
`node scripts/check-maps.mjs` and `git diff --check`. Full typecheck and
build were repeated successfully on final head
`0ecae0e9304f495a57524158b3700b8e9bc21cb8`. [Latest-head
CI](https://github.com/paperclipai/paperclip/actions/runs/39879208694)
is green: 54 checks passed and two skipped, including browser E2E and
serialized database suites.
- The new runtime controls execute real subprocesses with a controlled
installer. They cover an old CLI, an already compatible CLI, failed or
ineffective installation, local/custom commands, and an unknown version.
The probe regression asserts that the hello call uses the private
executable.
- A separate non-root local subprocess check installed the real npm
`@anthropic-ai/claude-code@2.1.280` package. Its private command
reported 2.1.280, the simulated image CLI remained 2.1.263, and a second
preparation reused the private copy. This ran on macOS ARM64. It did not
use a provider account, send a model prompt, or prove live Daytona
behavior.
- Attempted `pnpm test:run`. Embedded PostgreSQL initialization failed
after five attempts on this Mac with `Postgres init script exited with
code null`. The unchanged native-session database cases then failed.
Stopped only that full-suite process tree after recording the repeated
startup failure. No full local-suite pass is claimed; Linux CI must
cover those tests.
- The first new subprocess fixture had a quoting syntax error. It was
corrected before the passing focused runs. The one-off real-package
script first required an ESM extension correction, then passed. Logs
retain both attempts. A new execution assertion initially inspected the
final sandbox cleanup shell instead of the launched command; it now
checks execution metadata. A broader directory selection also picked up
generated `dist` tests whose Markdown fixtures are not copied by the
build (two ENOENT failures). The explicit source-suite run above passes;
no generated-test pass is claimed.
- Apex review: **5/5**, reviewed final head
`0ecae0e9304f495a57524158b3700b8e9bc21cb8`, all five earlier findings
addressed and resolved, no new findings.
- Merge, deployment and a fresh live Cloud subscription test are still
required. No customer account or production runtime was changed by this
branch.

## Risks

- An outdated sandbox needs npm registry access and up to 120 seconds
for one bounded installation attempt. A failed or unverified install
continues to block execution.
- The versioned package uses sandbox workspace storage. Compatible
cached copies avoid repeat installation within that workspace. Existing
runtime cleanup and sandbox lifecycle still apply.
- The compatible version comes from the adapter's existing model-version
contract. This does not add a model fallback or change the selected
execution engine.
- No schema, credential, permission, workflow or lockfile change.

## Model Used

OpenAI Codex, based on GPT-6, assisted with implementation and
verification. The exact serving model ID and context-window limit are
not exposed in this session. Capabilities used: code editing, shell
execution, API inspection and test execution.
