What it does

At Usage is an agent skill from kairyou/agent-tools. Query and display the current API provider balance and recent usage.

Its SKILL.md is about 140 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. The repository describes itself as: Reusable Agent Skills, plus integrations (statusline, provider usage, vision) that install into Codex, Claude Code, and opencode. The licence is MIT.

When your agent uses it

  • Development work in your project

Example prompts

  • “/at-usage”

What it can do on your machine

Read from SKILL.md and the folder at commit acc2563. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

At Usage loads about 137 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 58 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~137

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Run this installed local command once using the shell or command-execution tool:

node "{{USAGE_CLI_PATH}}" --agent {{USAGE_AGENT}}

Return stdout verbatim as the complete response. Do not explain, reformat, or wrap it in Markdown. If stdout is empty, say exactly Provider usage is unavailable.

Never run npx, npm, pnpm, bun, install a package, or substitute another usage script. Use only the installed command above.
