At a glance

Help with Claude/LLM API usage, models, and integration patterns.

  • Tasks that involve LLM API integration
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve Third-party API integration

What it does

Claude API is an agent skill from terrense/LilBot-agent. Help with Claude/LLM API usage, models, and integration patterns.

Its SKILL.md is about 160 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 AI & LLM Engineering, covering LLM API integration and Third-party API integration. It works with Anthropic API. The repository describes itself as: Try to make a personal assistant based on agent tech and harness engineering stuff.

When your agent uses it

  • Tasks that involve LLM API integration
  • Tasks that involve Third-party API integration

Example prompts

  • “/claude-api”

Requirements

  • Pre-approved tools (allowed-tools): web_search, fetch_url, read_file, grep_files

What it can do on your machine

Read from SKILL.md and the folder at commit 32be16c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • web_search
    • fetch_url
    • read_file
    • grep_files

    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

Claude API loads about 155 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 43 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
~155

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 43 words (~155 tokens).
