codex-sdd — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited codex-sdd (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
codex-sdd is the Codex adapter for the Software Development Department.
It does not replace Claude Code behavior. It helps Codex follow the existing SDD contract without changing the Claude-native runtime.
Treat these files as the SDD source of truth:
CLAUDE.md.claude/skills/using-sdd/SKILL.mddocs/technical/SDD_LIFECYCLE_MAP.md.claude/settings.json for Claude-only runtime behaviorUse using-sdd for routing. Use this skill only for Codex-specific adaptation.
Do not change these for Codex-only reasons:
.claude/settings.json.claude/hooks//plan, /spec, /tdd, /context, or otherSDD commands
Codex compatibility must be additive unless the user explicitly approves a broader Claude regression-tested change.
At the start of a Codex session in SDD:
AGENTS.md..claude/skills/using-sdd/SKILL.md.docs/technical/SDD_LIFECYCLE_MAP.md for phase orientation.| Claude-style tool | Codex equivalent |
|---|---|
Read | shell read commands or direct file inspection |
Glob | rg --files or shell listing |
Grep | rg |
Write | apply_patch |
Edit | apply_patch |
Bash | shell_command |
RunCommand | shell_command |
Task | spawn_agent only when explicitly authorized |
TodoWrite | update_plan |
AskUserQuestion | concise direct user question |
WebSearch | web search only when required or explicitly requested |
Claude Code hooks in .claude/settings.json do not run automatically in Codex. Use manual equivalents:
| Claude behavior | Codex behavior |
|---|---|
| Session bootstrap | Read AGENTS.md, using-sdd, lifecycle map, and relevant memory. |
| Pre-code gate | State the SDD pre-code gate before edits. |
| Bash safety | Follow Codex sandbox and escalation rules. |
| File history | Use git log -- <file> when needed. |
| Write logging | Use git diff/status and final changed-file summary. |
| Circuit guard | Inspect .claude/memory/circuit-state.json before subagent workflows. |
| Completion gate | Use verification-before-completion before success claims. |
Before implementation edits, state:
Pre-code gate: <Fast|Spec|Plan|Interview|Override> satisfied by <evidence>; next edit: <file>; verification: <command/check>.If the gate is not satisfied, stop and ask for the missing approval or clarification.
For SDD repo changes, run:
powershell -ExecutionPolicy Bypass -File scripts\codex-preflight.ps1If verification cannot be run, say exactly what was skipped and why.
For narrower checks, use:
powershell -ExecutionPolicy Bypass -File scripts\validate-skills.ps1
