At a glance

A skill your agent uses when reading or writing YAML configuration files, loading vehicle parameters, or handling config file parsing with proper error handling.

  • Writing YAML configuration files
  • SKILL.md covers Reading YAML, Writing YAML, Options and Error Handling, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Loading vehicle parameters

What it does

YAML Config is an agent skill from benchflow-ai/skillsbench. Use this skill when reading or writing YAML configuration files, loading vehicle parameters, or handling config file parsing with proper error handling.

Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: SkillsBench evaluates how well skills work and how effective agents are at using them. The licence is Apache-2.0.

When your agent uses it

  • Writing YAML configuration files
  • Loading vehicle parameters
  • Handling config file parsing with proper error handling

Example prompts

  • “/yaml-config”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 9a1f4dd. 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

YAML Config loads about 395 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 34 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~395

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.

YAML Configuration Files

Reading YAML

Always use safe_load to prevent code execution vulnerabilities:

python
import yaml

with open('config.yaml', 'r') as f:
    config = yaml.safe_load(f)

# Access nested values
value = config['section']['key']

Writing YAML

python
import yaml

data = {
    'settings': {
        'param1': 1.5,
        'param2': 0.1
    }
}

with open('output.yaml', 'w') as f:
    yaml.dump(data, f, default_flow_style=False, sort_keys=False)

Options

  • default_flow_style=False: Use block style (readable)
  • sort_keys=False: Preserve insertion order
  • allow_unicode=True: Support unicode characters

Error Handling

python
import yaml

try:
    with open('config.yaml', 'r') as f:
        config = yaml.safe_load(f)
except FileNotFoundError:
    config = {}  # Use defaults
except yaml.YAMLError as e:
    print(f"YAML parse error: {e}")
    config = {}

Optional Config Loading

python
import os
import yaml

def load_config(filepath, defaults=None):
    """Load config file, return defaults if missing."""
    if defaults is None:
        defaults = {}

    if not os.path.exists(filepath):
        return defaults

    with open(filepath, 'r') as f:
        loaded = yaml.safe_load(f) or {}

    # Merge loaded values over defaults
    result = defaults.copy()
    result.update(loaded)
    return result
