Plexum ProviderPlugin that wraps the local `codex` CLI binary
(OpenAI Codex CLI ≥ 0.135). Same CLI-driven pattern as
Plexum-gemini-provider and Plexum-anthropic-provider's contractor.
internal/runner/ (~200 LOC):
- Per Plexum turn, fork:
codex exec [resume <thread_id>] \
--skip-git-repo-check \
--dangerously-bypass-approvals-and-sandbox \
--json \
[--model <m>] \
"<last user msg>"
in agent workspace, with stdin = /dev/null (codex would otherwise
block waiting for additional input).
- Stream-parses JSONL events:
thread.started → save thread_id to .plexum-codex-session
item.completed → if type==agent_message, emit text_delta
turn.completed → capture usage (input/output/cached/reasoning)
error / turn.failed → emit canonical EventError
- Other event types (turn.started, item.started, reasoning, etc.)
logged at debug, don't produce user-facing events for v1
cmd/plexum-openai-provider-plugin/ implements ProviderPluginWithAgent
(needs AgentContext.Workspace as cwd).
Model surface:
default: ["codex"] (no --model flag → CLI default; only thing
ChatGPT-account installs support)
override via config.supported_models + config.model_args for
API-key installs that want gpt-5 / o3 / etc.
HostConfig (all optional):
binary default "codex" (operator should set abs path for
systemd PATH)
extra_args appended before the prompt
supported_models override the advertised model list
model_args map plexum id → CLI --model value
No api_key field — codex CLI handles auth via ~/.codex/ state
(ChatGPT login OR OPENAI_API_KEY env).
End-to-end verified against local install (ChatGPT login):
1. CLI turn 1: "OpenAI built me."
2. CLI turn 2 (resume): "I said: 'OpenAI built me.'" (multi-turn ✓)
3. Fabric channel e2e: alice → cx agent → codex CLI → outbound REST →
seq=23: "Use list comprehensions for concise, readable filtering and
transformation of iterables."
Known: when daemon runs under systemd PATH doesn't include nvm/local
bin dirs; operator must set absolute binary path in config.json.
