model-usage

model-usage is a skill for Claude Code, Codex from L-LesterYu/OpenClaw-hot-skills-zh. It costs 75 tokens per session (572 once invoked), scanned A, original, MIT.

A command-line tool and TypeScript toolkit for connecting to MCP servers. MCP is a standard way for AI agents to use external tools and services.

In plain words
What is it for?
It is for discovering configured MCP servers, calling their tools, creating temporary connections, generating command-line tools, and producing typed TypeScript clients.
Why use it?
It removes much of the manual work of finding, authenticating, configuring, and calling MCP tools across different connection types. It also avoids writing custom command-line wrappers or data pipes.

Token cost

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.

Security

Grade A, and why

model-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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/model_usage.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

模型使用情况

概述

从 CodexBar 的本地成本日志中获取按模型的使用成本。支持"当前模型"(最新的每日条目)或"所有模型"摘要,适用于 Codex 或 Claude。

待办:一旦 CodexBar CLI 在 Linux 上的安装路径有文档说明,将添加 Linux CLI 支持指南。

快速开始

  1. 通过 CodexBar CLI 获取成本 JSON 或传递一个 JSON 文件。
  2. 使用捆绑的脚本按模型汇总。
python {baseDir}/scripts/model_usage.py --provider codex --mode current
python {baseDir}/scripts/model_usage.py --provider codex --mode all
python {baseDir}/scripts/model_usage.py --provider claude --mode all --format json --pretty

当前模型逻辑

  • 使用包含 modelBreakdowns 的最新每日行。
  • 选择该行中成本最高的模型。
  • 当缺少细分时,回退到 modelsUsed 的最后一个条目。
  • 当需要特定模型时,使用 --model <name> 覆盖。

输入

  • 默认:运行 codexbar cost --format json --provider <codex|claude>
  • 文件或标准输入:
codexbar cost --provider codex --format json > /tmp/cost.json
python {baseDir}/scripts/model_usage.py --input /tmp/cost.json --mode all
cat /tmp/cost.json | python {baseDir}/scripts/model_usage.py --input - --mode current

输出

  • 文本(默认)或 JSON(--format json --pretty)。
  • 数值仅为每个模型的成本;CodexBar 输出中未按模型拆分 token。

参考资料

  • 阅读 references/codexbar-cli.md 了解 CLI 标志和成本 JSON 字段。
Files

What ships with it

3 files 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.

Changes

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.
