Guide for creating tools using CallableTool2 and Params pattern, plus YAML agent registration

  • SKILL.md covers Quick Template, Key Patterns and Registration
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Tool is an agent skill from Sikao-Engine/KimiX. Guide for creating tools using CallableTool2 and Params pattern, plus YAML agent registration

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/guide.md`).

The repository describes itself as: The next-gen lightweight coding agent cli.

Example prompts

  • “/tool”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 7394085. 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 (its code samples are python).

    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

Tool loads about 638 tokens when it runs, and up to ~3.3k if it reads all its reference files. Until then it costs about 25 tokens; SKILL.md has 137 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~25
When it runs · the whole SKILL.md, loaded when a task matches
~638
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.3k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 137 words (~638 tokens).

“Create custom tools with the CallableTool2 + Params pattern, then register them in a YAML agent file.”
