Purpose

Let Codex run autonomously in a sandbox to scaffold, refactor, and validate code without approvals.

Trigger Conditions

  • Use this skill when: Need overnight builds, unattended refactors, or autonomous scaffolding in a sandbox.
  • Reroute when: If work needs human-in-loop or policy-heavy guardrails, use codex-reasoning instead.

Guardrails (Inherited from Skill-Forge + Prompt-Architect)

  • Structure-first: every platform skill keeps SKILL.md, examples/, and tests/ populated; create resources/ and references/ as needed. Log any missing artifact and fill a placeholder before proceeding.
  • Confidence ceilings are mandatory in outputs: inference/report 0.70, research 0.85, observation/definition 0.95. State as Confidence: X.XX (ceiling: TYPE Y.YY).
  • English-only user-facing text; keep VCL markers internal. Do not leak internal notation.
  • Adversarial validation is required before sign-off: boundary, failure, and COV checks with notes.
  • MCP tagging for runs: WHO=codex-auto-{session}, WHY=skill-execution, namespace skills/platforms/codex-auto/{project}.

Execution Framework

  1. Intent & Constraints — clarify task goal, inputs, success criteria, and risk limits; extract hard/soft/inferred constraints explicitly.
  2. Plan & Docs — outline steps, needed examples/tests, and data contracts; confirm platform-specific policies.
  3. Build & Optimize — apply platform playbook below; keep iterative checkpoints and diffs.
  4. Validate — run adversarial tests, measure KPIs, and record evidence with ceilings.
  5. Deliver & Hand off — summarize decisions, artifacts, and next actions; capture learnings for reuse.

Platform Playbook

  • Workflow patterns:
    • Kick off full-auto scaffolds with explicit acceptance tests
    • Queue unattended refactors guarded by linters and smoke tests
    • Collect execution logs and diffs for review on return
  • Anti-patterns to avoid: Running against production directories, Allowing network access during full-auto runs, Skipping diff review before merge
  • Example executions:
    • codex --full-auto Scaffold CRUD API with tests
    • codex --full-auto Refactor to TS strict mode and fix type errors

Documentation & Artifacts

  • SKILL.md (this file) is canonical; keep quick-reference notes in README.md if present.
  • examples/ should hold runnable or narrative examples; tests/ should include validation steps or checklists.
  • resources/ stores helper scripts/templates; references/ stores background links or research.
  • Update metadata.json version if behavior meaningfully changes.

Verification Checklist

  • Trigger matched and reroute considered
  • Examples/tests present or stubbed with TODOs
  • Constraints captured and confidence ceiling stated
  • Validation evidence captured (boundary, failure, COV)
  • MCP tags applied for this run

Confidence: 0.70 (ceiling: inference 0.70) - Standardized platform skill rewrite aligned with skill-forge + prompt-architect guardrails.
