Run opencode (v2) CLI as a headless, fully-isolated test harness against any OpenAI-, Responses- or Messages-compatible endpoint (local inference engine or remote API), or against any provider credential already stored in an opencode profile (API key or login). Drives multi-step tool-calling scenarios, dumps NDJSON transcripts, and diagnoses model + chat-template + tool-parser failures without touching the caller's opencode profile (no MCP servers, no plugins, no project config, no shared…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# opencode-ci-harness

Targets opencode **v2** (`opencode --version` → `v2.x`). On v1 the runner
fails: v1 has no `--standalone`.

## Rules

| Never | Instead |
|---|---|
| Call `opencode run` directly for a test | `scripts/isolated-run.sh` — sets the whole envelope |
| Run without `--standalone` | The default connects to the operator's background service, which uses the operator's config, credentials and MCP servers |
| Share a data dir with any other opencode process | Fresh scratch `XDG_DATA_HOME` per run (runner does it). The background service resumes unfinished sessions it finds in its data dir, without the run's permissions or step limit |
| Pass/fail on `$?` | Assert on NDJSON events (`scripts/assert-tool-sequence.sh`) |
| Print, log or copy a credential value | `--credential` pipes it into the scratch DB; it never touches disk outside it |
| Copy an OAuth refresh token | `inject-credential.py` withholds it and refuses tokens expiring within `--timeout` + 10 min |
| Use `--pure`, `--dir`, `OPENCODE_PURE`, `OPENCODE_AUTH_CONTENT`, `OPENCODE_DISABLE_DEFAULT_PLUGINS` | Removed in v2 — see `references/isolation.md` |

How to install

The exact contents, by fingerprint
mdr add air-gapped/skills/opencode-ci-harness@sha256:fd652ee8db3d3d25

The line at the top of this page pins the label git:20261019.93a4ddd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
