arcgentic

name	arcgentic
description	Use when the user says Arcgentic, asks to use Arcgentic, or wants an idea taken through a complete plan → development → self-audit → external audit workflow in Codex.

Arcgentic

This is the Codex-facing entry skill for Arcgentic V2.

Use this before build-feature, executing-plans, or direct coding whenever the user asks to use Arcgentic.

Do not directly implement, test, or scaffold the requested feature from the Orchestrator, even in a greenfield or empty project. Arcgentic work starts by dispatching Planner.

Immediate behavior in Codex

1. Treat the current thread as Orchestrator and rename the current Codex thread to exactly Orchestrator before dispatching any role.
2. Determine whether the current thread has a real project/workspace root.
   • If yes, continue with project-scoped orchestration.
   • If no, stop and ask the user to open or create a saved project workspace.
3. If this is the first Arcgentic V2 run in the project and no mode is already stored, judge the user's idea before dispatching Planner:

   • Run:

     arcgentic session-mode recommend-v2 --idea '<current user request>'
     

   • Present the recommended mode, confidence, reasons, and tradeoff in natural language.

   • Ask the user to confirm the recommendation or override it.

   • Do not dispatch Planner until the user has chosen one project-level mode.

4. The two V2 modes are:
   • single-session-subagent: faster and usually finishes sooner. Planner, Developer, Test, and Auditor run as named subagents inside the current Orchestrator session, so audit isolation is weaker. The first use of a role creates that fixed named role identity; later rounds reuse it.
   • multi-session-subthread: slower. Planner, Developer, Test, and Auditor run in fixed project threads, so role separation and external-audit evidence are stronger.
5. Use the chosen mode for the whole project. Do not ask again per round unless the user explicitly starts a new project or requests a reset.
6. In multi-session-subthread, use the current project/workspace as the only valid target for role threads after initialization.
7. Do not create projectless Planner / Developer / Test / Auditor threads.
8. Use the strongest available Codex model for real Planner / Developer / Test / Auditor work. Do not default role threads to a lightweight or spark model unless the user explicitly asks for a low-cost smoke test.
9. Record the current thread as fixed role Orchestrator in .agentic-rounds/state.yaml before dispatching Planner. If the host cannot provide the current Orchestrator thread id, stop because push-return cannot work. In Codex delegation-created threads, do not treat the delegation source_thread_id as the current Orchestrator id. It identifies the upstream supervising thread, not the project-scoped Orchestrator.
10. Before reading implementation files, running tests, checking git log, or summarizing prior work, initialize/check .agentic-rounds/state.yaml and run v2-session-plan.
11. Initialize .agentic-rounds/state.yaml if it does not exist. If state exists and current_round.state is closed, treat the new user request as input for Planner only when it asks for new work. Status, inspection, review, or "is this complete?" requests are terminal idle and must not rewrite active_user_request or dispatch Planner.
12. Run v2-session-plan with the user-selected mode on first use, or without --mode after the mode is already stored:

arcgentic v2-session-plan \
  --state .agentic-rounds/state.yaml \
  --host codex \
  --user-request '<current user request>' \
  --mode <single-session-subagent|multi-session-subthread>

13. If the plan is active and contains an action, dispatch that one role before any verification or implementation inspection, then call arcgentic v2-dispatch-role and end the Orchestrator turn in multi-session-subthread, or create/reuse the named role agent directly in single-session-subagent. If state is closed and the plan has no actions, stop: the round is terminal at the project level, all role threads are idle, and Orchestrator should wait for a new user request.
14. Load codex-thread-orchestration and follow it.

Bootstrap if state is missing

Find the plugin root:

PLUGIN_ROOT="${ARCGENTIC_PLUGIN_ROOT:-$HOME/plugins/arcgentic}"

Then initialize state:

bash "$PLUGIN_ROOT/scripts/state/init.sh" \
  --project-root . \
  --project-name "$(basename "$PWD")" \
  --round-naming "R<n>"

After init, update the state for V2 Codex mode:

python - <<'PY'
from pathlib import Path
import yaml

path = Path(".agentic-rounds/state.yaml")
state = yaml.safe_load(path.read_text(encoding="utf-8"))
state.setdefault("project", {})["arcgentic_v2"] = {
    "host": "codex",
    "role_sessions": {},
}
path.write_text(yaml.safe_dump(state, sort_keys=False), encoding="utf-8")
PY

Fail-closed rules

• If arcgentic CLI is not available, report installation failure instead of pretending Arcgentic is active.

• If the current thread is projectless or cannot create project-scoped role threads, stop.

• If .agentic-rounds/state.yaml records delegation source_thread_id as the Orchestrator session by mistake, do not create Planner. Repair only that field with:

  arcgentic v2-record-session \
    --state .agentic-rounds/state.yaml \
    --host codex \
    --role orchestrator \
    --thread-id <current-orchestrator-thread-id> \
    --title Orchestrator \
    --repair-current-orchestrator
  

• If .agentic-rounds/state.yaml cannot be created or validated, stop.

• If role threads cannot be created in the current project/workspace, stop.

• If a role thread is slow, send at most one status/constraint-tightening message. If it still does not return a valid RoleReturnSignal, stop with a role-timeout status. Do not continue the workflow in the Orchestrator.

• After dispatching a role prompt, call arcgentic v2-dispatch-role and end the Orchestrator turn. The Orchestrator resumes only when the pending role actively sends return information back to the Orchestrator thread.

• If arcgentic v2-return-signal rejects the role output, stop and report the rejected signal. Do not repair it by hand in the Orchestrator.

• Do not silently fall back to "Arcgentic-style" hand-written evidence.

• Do not treat "greenfield" or "empty repo" as permission for Orchestrator implementation.

• Do not verify, summarize, or inspect a previous closed round as the response to a new implementation request. Route the request to Planner first.

• Do not auto-dispatch Planner from project-level closed unless there is a new user request. Closed without a new request means the project workflow is stopped. Round-level PASS is not closed; it must advance through the stored project plan.

• Do not run ordinary coding work before Planner has produced or approved the round plan.

• Planner, Developer, Test, and Auditor must not mutate .agentic-rounds/state.yaml, run transition commands, dispatch roles, consume RoleReturnSignal, or close rounds. They write their role-owned artifacts and return natural-language output plus one arcgentic-role-return footer for the Orchestrator to consume.
