lcp_tool_building SKILL.md skillB
lcp_tool_building from parisneo/lollms_client is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add parisneo/lollms_client/lcp_tool_building@git:20261012.529309ePins git:20261012.529309e in mdr.lock. Pin the fingerprint instead.

Practical how-to for authoring LCP tools: tool function anatomy, docstring-driven schemas, requesting execution privileges via the confirm handler, and collecting user input (text, secrets, select-from-list) mid-execution from the CLI or GUI.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Building LCP Tools: Privilege Requests & User Input Collection
A hands-on guide to **writing** LCP tools. For binding architecture, discovery internals, and mounting APIs, see the `lcp_tool_development` skill. This skill covers only what a tool author needs: function anatomy, schemas, asking for privileges, and asking the user for information.
---
## 1. Minimal Tool Anatomy
An LCP tool is a plain Python function named `tool_*` in a `.py` file inside a tools folder (e.g. `.lollms_code/tools/my_tool/my_tool.py`):
```python
from typing import Any, Dict
def tool_greet(name: str, enthusiasm: int = 1) -> Dict[str, Any]:
"""
Greets a person with adjustable enthusiasm.
Args:
name (str): The name of the person to greet.
enthusiasm (int): Number of exclamation marks (1-5).
"""
return {"success": True, "output": f"Hello {name}" + "!" * max(1, min(5, enthusiasm))}
```
**Rules that matter to you:**
- The **function name** is the tool name (`tool_greet`). Prefix anything else with `_` to keep it private.
- The **first docstring paragraph** becomes the LLM-facing description.
- `Args:` lines in the form `name (type): desc` document parameters.

How to install
mdr add parisneo/lollms_client/lcp_tool_building@sha256:ddd44ddf748e1349The line at the top of this page pins the label git:20261012.529309e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
