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 5.1 | $0.00026 | $0.00443 |
| Opus 5.5 | $0.00010 | $0.00177 |
| Sonnet 5.5 | $0.00005 | $0.00089 |
| Haiku 4.5 | $0.00003 | $0.00044 |
Grade A, and why
codex-usage 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 29d 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.
What it actually says
Codex Usage
读取当前 macOS 用户的 Codex CLI 登录状态，并查询 ChatGPT Codex 订阅额度。只提供手动查询，不创建或管理定时任务。
动作
status：检查~/.codex/auth.json是否存在、访问令牌是否仍有效、是否能取得 account ID。所有凭据均脱敏。query：查询当前套餐、session/weekly 窗口、credits、spend_control、可用重置次数、额外限额、code review 限额、promo/referral 等接口字段，并返回打码后的 raw_response_redacted。
Authentication
默认读取系统当前用户的 ~/.codex/auth.json。由于 AgentDock 的 HOME 可能指向 workspace，Skill 通过系统用户数据库定位真实用户目录。可通过 CODEX_HOME 覆盖 Codex 配置目录。
Security
- 不接受 token 作为输入。
- 不输出 access token、refresh token、ID token、Authorization header 或真实 account ID、真实 user ID 或真实邮箱。
- 只读认证文件，不修改 Codex 登录状态。
- 只访问 ChatGPT Codex usage 接口。
辅助脚本执行
Skill 本体是本说明文档。确需调用包内辅助脚本时，在 Skill 包根目录使用相对路径执行；运行宿主负责切换到包根目录并把所需变量注入当前子进程。
printf '%s' '{"skill_action":"<动作>"}' | python3 run.py
输入必须是 JSON 对象。写操作仍按本文档中的确认规则执行。
| 动作 | 用途 |
|---|---|
status |
Check local Codex CLI login state without revealing credentials. |
query |
Query Codex usage and expose the full redacted usage API payload plus parsed quota fields. |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-usage is a skill published in the GitHub repository uvwt/agentdock-skills (6 stars, last pushed 8d ago), licensed Apache-2.0. It adds 26 tokens to every session and 443 once invoked, about $0.0001 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 2026-08-31.
