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.

SkillSpector: 4 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 5.1 | $0.00095 | $0.01736 |
| Opus 5.5 | $0.00038 | $0.00694 |
| Sonnet 5.5 | $0.00019 | $0.00347 |
| Haiku 4.5 | $0.00010 | $0.00174 |
Grade A, and why
codex scanned grade A with 0 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 21d ago.
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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Codex CLI Delegation for Agent's Shell Tool
This skill is written for shell tool. Assume there is no PTY. Do not use interactive Codex TUI flows.
Non-Interactive Rules
- Use
codex execfor every delegated task. - Do not run bare
codex,codex resume, app-server flows, desktop app flows, tmux, or commands that wait for keyboard input. - Do not pass PTY-only options such as
pty=true. - Place global flags after the subcommand, for example
codex exec --cd "$PROJECT" .... - Prefer
--sandbox workspace-write --ask-for-approval neverfor implementation tasks. This keeps edits inside the workspace and avoids approval prompts that the shell cannot answer. - Use
--sandbox read-onlyfor review, diagnosis, or planning tasks. - Avoid
--dangerously-bypass-approvals-and-sandbox/--yolounless the user explicitly asks for an unsafe fully trusted run. - Do not install Codex automatically unless the user asked you to. If missing, fall back to Claude Code or work directly.
Selection Policy
Prefer Codex first for coding work. Before invoking it, run a quick availability check:
if command -v codex >/dev/null 2>&1; then
codex --version
codex login status >/dev/null 2>&1
elif command -v claude >/dev/null 2>&1; then
echo "Codex is unavailable; use the claude-code skill instead."
else
echo "Neither codex nor claude is installed; continue directly or ask the user to install one."
fi
Interpret the result:
codexmissing: use theclaude-codeskill ifclaudeis installed, otherwise solve with available tools or ask the user to install Codex.codex login statusfails: tell the user to runcodex login(or configure their API key) and use Claude Code if available.- Both CLIs available: keep Codex as the default unless the user specifically asked for Claude Code.
Preflight Checklist
Before delegating:
- Identify the project root:
git rev-parse --show-toplevel 2>/dev/null || pwd. - Check the current diff with
git status --shortso user-owned changes are visible. - Convert the user's request into a concise task prompt with success criteria, files or areas to inspect, constraints, and expected verification commands.
- Decide sandbox mode:
workspace-writefor edits,read-onlyfor reviews. - Decide whether the task is small enough to do directly. Use Codex for broad, multi-file, uncertain, or test-heavy coding work.
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 skill published in the GitHub repository ldclabs/anda-bot (26 stars, last pushed yesterday), licensed Apache-2.0. It adds 95 tokens to every session and 1,736 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
