## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - The OpenCode adapter validates that its configured model exists
before letting
>   a run start so misconfiguration fails fast with a clear error
> - SSH testing reproduced an OpenCode failure where issues stayed
`backlog`,
>   timed out, and produced no comments. The root cause was in
> `packages/adapters/opencode-local/src/server/execute.ts`: the local
model
> guard `ensureOpenCodeModelConfiguredAndAvailable(...)` only ran when
execution
> was *not* remote, so SSH OpenCode bypassed it and failed silently
later
> - Subsequent testing surfaced a related remote-only failure where the
probe
> (when wired up naively) hits `EACCES: permission denied, mkdir
'/var/folders'`
> on the SSH box because of how OpenCode's runtime config picks a
tempdir
> - This PR runs the model probe on the actual execution target —
`opencode
> models` via `runAdapterExecutionTargetProcess` — instead of the local
CLI,
> parses the output with the shared `parseOpenCodeModelsOutput` helper,
and
> reports a concrete error naming the offending model and a sample of
available
>   remote models when the configured model isn't present
> - The benefit is that mismatched OpenCode models surface as a clear
pre-flight
> error referencing the remote target instead of a silent run that never
leaves
>   `backlog`

## What Changed

- Added `ensureRemoteOpenCodeModelConfiguredAndAvailable` in
  `opencode-local/src/server/execute.ts` that runs `opencode models` via
`runAdapterExecutionTargetProcess` and validates the configured model is
in
  the parsed output
- `models.ts` now exports `parseOpenCodeModelsOutput` and
`requireOpenCodeModelId`
  so the remote path can reuse them
- `execute.ts` calls the remote variant when `executionTargetIsRemote`,
otherwise
  the existing local `ensureOpenCodeModelConfiguredAndAvailable`
- Errors include the offending model id and a sample of available remote
models
  so the operator knows exactly what's missing
- `execute.remote.test.ts` extended with cases for: probe timeout, probe
  non-zero exit, empty model list, and missing-model error

## Verification

- `pnpm --filter @paperclipai/adapter-opencode-local test`
- `pnpm test -- opencode-local`
- Manual QA: configured an OpenCode agent with a model that exists
locally but
not in the remote sandbox, and confirmed the new error fires before the
run
  starts and references the remote target

## Risks

- New behaviour: remote model validation adds a `~20s timeout` `opencode
models`
call on every remote run start. For most environments this is fast, but
a
network-slow sandbox could see startup latency rise. Timeout is bounded.
- If the remote CLI is missing or misconfigured, the new error replaces
the old
generic startup failure — clearer message, but the failure point shifts
earlier. Monitor for any QA flows that relied on the old failure shape.

## Model Used

- OpenAI GPT-5.4 (reasoning effort: high) via Codex CLI
- Provider: OpenAI
- Used to author the code changes in this PR
