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 | $0.00013 | $0.01366 |
| Opus 5 | $0.00006 | $0.00683 |
| Sonnet 5 | $0.00003 | $0.00273 |
| Haiku 4.5 | $0.00001 | $0.00137 |
Grade B, and why
codex scanned grade B with 1 finding 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context
- Working directory: !
pwd - Plugin root: ${CLAUDE_PLUGIN_ROOT}
- Codex installed: !
codex --version 2>&1 || echo "NOT INSTALLED"
Task
Act as an orchestration layer: understand the user's intent, gather relevant context, compose a self-contained prompt, send it to Codex, and analyze the result.
User request: $ARGUMENTS
Step 1: Pre-checks
- If Codex is not installed (version shows "NOT INSTALLED"), tell the user: "Codex CLI is not installed. Run
npm install -g @openai/codexto install, thencodex loginto configure your API key." Stop here. - If $ARGUMENTS is blank, ask the user what they want Codex to do. Provide 2-3 example prompts based on the current project context (e.g., files recently discussed). Do not proceed with an empty prompt.
Step 2: Understand Intent
Analyze $ARGUMENTS and resolve any ambiguous or contextual references:
- Resolve vague references — "that function", "the file we discussed", "this bug" → look back at conversation history to identify specific file paths, function names, or code snippets.
- Identify the task type — analysis, verification, comparison, documentation review, etc.
- Determine scope — which files, directories, or code regions are relevant.
If a reference cannot be resolved from conversation context, ask the user for clarification rather than guessing.
Step 3: Collect Context
Based on the resolved intent, gather only the directly relevant context. Use these tools as needed:
| Need | Action |
|---|---|
| File content discussed in conversation | Read key files or snippets (keep to relevant sections) |
| Recent changes | git diff --stat, git diff <file> for specific files |
| Project structure | ls relevant directories |
| Git state | git status --short, git log --oneline -5 |
| Current branch | git branch --show-current |
Limits: Collect only what Codex needs to do the job. Total context should not exceed ~200 lines. Prefer targeted snippets over full file dumps.
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.

codex is a command published in the GitHub repository DropFan/claude-code-plugins (7 stars, last pushed 26d ago), licensed MIT. It adds 13 tokens to every session and 1,366 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
