Claude-code-minoan codex-cto

Inverted orchestration—Codex CLI acts as CTO (planning and reviewing), Claude Code executes with native tools. Use when a task benefits from external architectural oversight before and after implementation.

Codex CTO — Inverted Orchestration

Codex plans and reviews. Claude Code executes. This inverts the

codex-orchestrator
pattern: instead of Claude Code delegating to Codex subagents, Codex directs Claude Code as the engineering team.

Protocol

1. CTO plans   →  cto-invoke.sh plan "<objective>"
2. You execute  →  native tools (Read, Edit, Write, Bash, Glob, Grep)
3. CTO reviews  →  cto-invoke.sh review "<objective + results>"
4. Loop         →  if "revise", fix and re-submit for review (max 5 iterations)

Step 1: Get the Plan

Run the plan phase with the user's objective:

~/.claude/skills/codex-cto/scripts/cto-invoke.sh plan "<OBJECTIVE>" [--model MODEL]

Parse the returned JSON. It contains:

  • objective
    — what to accomplish
  • analysis
    — CTO's assessment of the codebase
  • strategy
    — high-level approach
  • tasks[]
    — ordered task list with IDs, actions, targets, descriptions, acceptance criteria, and dependencies
  • verification
    — commands to run after all tasks complete

Step 2: Execute Tasks

Work through each task in dependency order using native tools. For each task:

  1. Read the
    description
    and
    acceptance_criteria
  2. Execute the action (
    create_file
    ,
    modify_file
    ,
    delete_file
    ,
    run_command
    ,
    verify
    )
  3. Verify each acceptance criterion before moving to the next task
  4. Track what was done and what the outcome was

Do not deviate from the plan without reason. If a task is blocked or the plan has an error, note it and continue with unblocked tasks. Report blockers in the review submission.

Step 3: Submit for Review

After executing all tasks, run the review phase. Include the original objective and a summary of what was done:

~/.claude/skills/codex-cto/scripts/cto-invoke.sh review "<OBJECTIVE>. Results: <summary of what was done, any issues encountered>"

Parse the returned JSON:

  • verdict: "approve"
    — done. Report success to the user.
  • verdict: "revise"
    — check
    task_reviews
    for feedback and
    revised_tasks
    for new/updated tasks. Fix issues and re-submit.
  • verdict: "abort"
    — fundamental problem. Report the CTO's
    reason
    to the user and stop.

Step 4: Iterate (if revise)

On a "revise" verdict:

  1. Read each
    task_reviews
    entry with status
    fail
    or
    partial
  2. Execute the fixes described in
    feedback
    and any
    revised_tasks
  3. Re-submit for review (step 3)
  4. Maximum 5 review iterations. If the CTO issues 3 consecutive "revise" verdicts, escalate to the user.

Model Selection

The

--model
flag passes through to
codex exec
. Available models:

ModelIDNotes
GPT-5.4 Pro
gpt-5.4-pro
Default for plan phase. Deepest reasoning for architectural decomposition.
GPT-5.4
gpt-5.4
Default for review phase. Unified coding + reasoning flagship.
GPT-5 Mini
gpt-5-mini
Cost-optimized, fast iteration.
GPT-5.3-Codex
gpt-5.3-codex
Previous generation. Still functional.

Omit

--model
to use the default from
~/.codex/config.toml
.

Options

OptionDescription
--model <id>
Override model (default: config default)
--dry-run
Print command without executing

Artifacts

Plan and review JSON files are saved to

.codex-cto/<PID>/
in the working directory. Each invocation creates sequentially numbered files (
plan-001.json
,
review-001.json
, etc.). PID namespacing prevents conflicts between concurrent sessions.

Diagnostics

Reuse codex-orchestrator's status script for CLI diagnostics:

~/.claude/skills/codex-orchestrator/scripts/codex-status.sh

Examples

# Simple feature
/codex-cto Add a health check endpoint at /health returning {status: "ok"}

# With model override
/codex-cto Refactor the auth module to use JWT --model gpt-5-mini

# Dry run to inspect the command
~/.claude/skills/codex-cto/scripts/cto-invoke.sh plan "Add rate limiting" --dry-run

Sister Skill

This skill is the inverse of

codex-orchestrator
. Use
codex-orchestrator
when Claude Code should delegate one-shot specialist tasks to Codex. Use
codex-cto
when Codex should direct Claude Code through a plan-execute-review loop.
