Step-by-step Workflow

codex — Workflow

Auto-generated from SKILL.md. The skill itself is the source of truth; this is a human-readable map of what it does and how it runs.

What it does & when to use

OpenAI Codex CLI wrapper — three modes. Code review: independent diff review via codex review with pass/fail gate. Challenge: adversarial mode that tries to break your code. Consult: ask codex anything with session continuity for follow-ups. The "200 IQ autistic developer" second opinion. Use when asked to "codex review", "codex challenge", "ask codex", "second opinion", or "consult codex". (gstack) Voice triggers (speech-to-text aliases): "code x", "code ex", "get another opinion".

Triggers

  • 200 IQ autistic developer
  • codex review
  • codex challenge
  • ask codex
  • second opinion
  • consult codex
  • code x
  • code ex
  • get another opinion

How it works

Workflow outline (sections of SKILL.md):

  1. Preamble (run first)
  2. Plan Mode Safe Operations
  3. Skill Invocation During Plan Mode
  4. Skill routing
  5. AskUserQuestion Format
  6. Artifacts Sync (skill start)
  7. Model-Specific Behavioral Patch (claude)
  8. Voice
  9. Context Recovery
  10. Writing Style (skip entirely if EXPLAIN_LEVEL: terse appears in the preamble echo OR the user's current message explicitly requests terse / no-explanations output)
  11. Completeness Principle — Boil the Lake
  12. Confusion Protocol
  13. Continuous Checkpoint Mode
  14. Context Health (soft directive)
  15. Question Tuning (skip entirely if QUESTION_TUNING: false)
  16. Repo Ownership — See Something, Say Something
  17. Search Before Building
  18. Completion Status Protocol
  19. Operational Self-Improvement
  20. Telemetry (run last)
  21. Plan Status Footer
  22. Step 0: Detect platform and base branch
  23. Step 0.4: Check codex binary
  24. Step 0.5: Auth probe + version check
  25. Step 0.6: Resolve portable roots
  26. Step 1: Detect mode
  27. Filesystem Boundary
  28. Step 2A: Review Mode
  29. Plan File Review Report
  30. GSTACK REVIEW REPORT
  31. Step 2B: Challenge (Adversarial) Mode
  32. Step 2C: Consult Mode
  33. Model & Reasoning
  34. Cost Estimation
  35. Error Handling
  36. Important Rules

Components

Single-file skill — all instructions live in SKILL.md.

Invoke

  • Slash: /codex
  • Or a natural-language request matching the triggers above.

Source: SKILL.md in this directory.

Execution Logic

The skill executes when its trigger fires (slash command, natural-language match, or direct invocation). It reads its references, applies its rules, and produces the documented outputs.

Edge Cases

See the source skill's references/ and scripts/ folders for edge-case handling.

Failure Handling

A skill failure surfaces as a tool error or a partial output; never a silent skip. Re-run with --verbose (where applicable) for diagnostics.

Integration Notes

  • Claude — invoked via the Skill tool with skill: "codex".
  • Codex — referenced from AGENTS.md if mirrored.
  • Antigravity — referenced from the workspace agent rules if mirrored.
  • HQ Project — listed on the landing page Skills section + post-login sidebar.
  • MD Project (md.sgnk.ai) — file rendered from Skills/Codex/workflow.md.
  • Obsidian — file rendered with frontmatter + tags.

Usage Examples

Invoke via slash command or natural language matching the skill description.
