# Verifying harness changes on a docker-less host The pipeline's real surface is the in-container `claude -p` process and its outbound API requests. Without docker, drive the same pinned CLI binary directly with the env dict the harness would inject via `docker -e`. ## Recipe 1. **Get the pinned CLI** (version from `harness/agent_image.py:CLAUDE_CODE_VERSION`): `npm install --no-save @anthropic-ai/claude-code@<pin>` in a temp dir → binary at `node_modules/@anthropic-ai/claude-code/bin/claude.exe` (the `.exe` name is the real native-binary entry on Linux too, filled in by the package's postinstall — not a Windows leftover). 2. **Stub API server**: a tiny HTTP server that appends each request's headers to a JSONL file and returns a 400 `invalid_request_error` (non-retryable, so the CLI exits fast; exit=1 is expected). 3. **Build the agent env exactly as the pipeline does**: `python3 -c "from harness.auth import resolve_auth_env; ..."` and dump to an `export`-lines file with `shlex.quote` (values contain newlines — NEVER pass via `env $(...)`, word-splitting mangles them; `source` the file). 4. **Emulate the container env**: `unset ANTHROPIC_CUSTOM_HEADERS` (and any other ambient var not in the resolved dict) before sourcing — a Claude Code session in this repo injects `.claude/settings.json` env into shells, which containers never see. 5. **Run**: `ANTHROPIC_BASE_URL=http://127.0.0.1:<port> CLAUDECODE= IS_SANDBOX=1 timeout 30 <cli> -p hi --model claude-sonnet-4-5 --max-turns 1`, then read the captured JSONL. ## Gotchas - Unit tests in `tests/test_patch.py` / `tests/test_patch_grade.py` need docker and fail on docker-less hosts — pre-existing, not your change. - The docker `-e` injection leg itself can't be exercised without docker; it's the same mechanism that carries `ANTHROPIC_API_KEY` in production. - For the interactive-skills surface, copy `.claude/settings.json` into a fresh temp dir and run the host `claude` from there (with ambient `ANTHROPIC_CUSTOM_HEADERS` unset so settings.json is the only source).
