Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01412 | $0.01412 |
| Opus 5 | $0.00706 | $0.00706 |
| Sonnet 5 | $0.00282 | $0.00282 |
| Haiku 4.5 | $0.00141 | $0.00141 |
Grade F, and why
software_development_department AGENTS.md scanned grade F with 5 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- `chmod 777` Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
- Reading `~/.docker/config.json`, `~/.kube/config` Downloads and executes remote codehighSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
- `curl * | sh`, `curl * | bash` Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- `rm -rf /`, `rm -rf .`, `rm -rf /*`, `rm -rf ./*` Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- `curl * | sh`, `curl * | bash` How it starts
The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SDD for Codex
This repository is the Software Development Department (SDD) harness.
The canonical source of truth remains Claude-native:
CLAUDE.md.claude/settings.json.claude/agents/.claude/skills/.claude/hooks/.claude/memory/
Codex support is an adapter layer. Do not change Claude runtime behavior to make Codex work.
Operating Rule
Before any non-trivial software-development response, review:
.claude/skills/using-sdd/SKILL.mddocs/technical/SDD_LIFECYCLE_MAP.md- The specific SDD skill that matches the task
Use SDD's six-phase map:
DEFINE -> PLAN -> BUILD -> VERIFY -> REVIEW -> SHIP
For implementation work, state the pre-code gate before the first production edit:
Pre-code gate: <Fast|Spec|Plan|Interview|Override> satisfied by <evidence>; next edit: <file>; verification: <command/check>.
Codex Runtime Notes
Claude Code hooks in .claude/settings.json do not run automatically in Codex.
Codex must manually honor the same gates through instructions, file inspection,
and verification commands.
Preserve these boundaries:
- Do not move or rename
.claude/skills. - Do not move or rename
.claude/agents. - Do not weaken
.claude/settings.jsonpermissions. - Do not replace Claude hooks with Codex-specific behavior.
- Do not claim work is done without fresh evidence.
- Do not commit or push unless the user explicitly asks.
Safety Rules (Manual Deny List)
Claude Code enforces these rules automatically through hooks and permissions. Codex does not run those hooks, so you must enforce these rules manually.
Blocked Commands — NEVER Execute
These commands are forbidden. If a task seems to require one, stop and ask the user for explicit approval and an alternative approach.
Destructive filesystem:
rm -rf /,rm -rf .,rm -rf /*,rm -rf ./*mkfs,dd if=/dev/zero,dd if=/dev/nullchmod 777
Credential and secret exposure:
- Reading
.env,.env.*, or any*.envfile - Reading
~/.ssh/,~/.aws/,~/.azure/,~/.gnupg/,~/.config/gcloud/ - Reading
~/.docker/config.json,~/.kube/config - Writing to
.env,.env.*,.bashrc,.zshrc,.profile cat .env,type .env, or any command that outputs secret files
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

software_development_department AGENTS.md is an instructions file published in the GitHub repository tranhieutt/software_development_department (71 stars, last pushed 3mo ago), licensed MIT. It adds 1,412 tokens to every session, about $0.0071 per session on Opus 5. A static security scan graded it F with 5 findings (asks for root, reaches for credential files, downloads and executes remote code). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
