What it does
Config Skills is an agent skill from llama-farm/llamafarm. Configuration module patterns for LlamaFarm. Covers Pydantic v2 models, JSONSchema generation, YAML processing, and validation.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `jsonschema.md` and `pydantic.md`).
It works with Pydantic and Python. The repository describes itself as: Deploy any AI model, agent, database, RAG, and pipeline locally or remotely in minutes. The licence is Apache-2.0.
Example prompts
- “/config-skills”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Grep, Glob
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Edit schema.yaml (or referenced schemas like ../rag/schema.yaml)
- Run nx run generate-types to compile and generate types
- Update validators.py if new cross-field constraints are needed
- Test with uv run pytest config/tests/
What it can do on your machine
Read from SKILL.md and the folder at commit 6244d46. 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:
ReadGrepGlob
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
uvnxruff
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
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
Config Skills loads about 1.3k tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 243 words of instructions outside code blocks.
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.

Config Skills for LlamaFarm
Specialized patterns and best practices for the LlamaFarm configuration module (config/).
Module Overview
The config module provides YAML/TOML/JSON configuration loading with JSONSchema validation:
| File | Purpose |
|---|---|
datamodel.py | Generated Pydantic v2 models from JSONSchema |
schema.yaml | Source JSONSchema with $ref references |
compile_schema.py | Dereferences $ref to create schema.deref.yaml |
generate_types.py | Generates Python types via datamodel-codegen |
validators.py | Custom validators beyond JSONSchema capabilities |
helpers/loader.py | Config loading, saving, and format detection |
helpers/generator.py | Template-based config generation |
Links to Shared Skills
This module follows Python conventions from the shared skills:
| Topic | Link | Key Relevance |
|---|---|---|
| Patterns | python-skills/patterns.md | Pydantic v2, dataclasses |
| Typing | python-skills/typing.md | Type hints, constrained types |
| Testing | python-skills/testing.md | Pytest fixtures, temp files |
| Errors | python-skills/error-handling.md | Custom exceptions |
| Security | python-skills/security.md | Path traversal prevention |
Framework-Specific Checklists
| Checklist | Description |
|---|---|
| pydantic.md | Pydantic v2 configuration patterns, nested models, constraints |
| jsonschema.md | JSONSchema generation, dereferencing, validation |
Tech Stack
- Python: 3.11+
- Pydantic: v2 with
ConfigDict,Field, constrained types - JSONSchema: Draft-07 with
$refdereferencing viajsonref - YAML:
ruamel.yamlfor comment-preserving read/write - Code Generation:
datamodel-codegenfor schema-to-Pydantic
Key Patterns
Generated Pydantic Models
The datamodel.py file is auto-generated from JSONSchema:
# Generated by datamodel-codegen from schema.deref.yaml
from pydantic import BaseModel, ConfigDict, Field, conint, constr
class Database(BaseModel):
model_config = ConfigDict(extra="forbid")
name: constr(pattern=r"^[a-z][a-z0-9_]*$", min_length=1, max_length=50)
type: Type
config: dict[str, Any] | None = Field(None, description="Database-specific configuration")Custom Validators for Cross-Field Constraints
JSONSchema draft-07 cannot express all constraints. Custom validators extend validation:
def validate_llamafarm_config(config_dict: dict[str, Any]) -> None:
"""Validate constraints beyond JSONSchema (uniqueness, references)."""
# Check for duplicate prompt names
prompt_names = [p.get("name") for p in config_dict.get("prompts", [])]
duplicates = [name for name in prompt_names if prompt_names.count(name) > 1]
if duplicates:
raise ValueError(f"Duplicate prompt set names: {', '.join(set(duplicates))}")Comment-Preserving YAML with ruamel.yaml
Configuration files preserve user comments when modified:
from ruamel.yaml import YAML
from ruamel.yaml.comments import CommentedMap
def _get_ruamel_yaml() -> YAML:
yaml_instance = YAML()
yaml_instance.preserve_quotes = True
yaml_instance.indent(mapping=2, sequence=4, offset=2)
return yaml_instanceDirectory Structure
