Biome Config Validator
Validate biome.json configuration files for correctness, conflicts, deprecated options, and best practices.
Commands
# Validate a biome.json file (all rules)
python3 scripts/biome_config_validator.py lint biome.json
# Check for rule conflicts only
python3 scripts/biome_config_validator.py conflicts biome.json
# Check for deprecated options
python3 scripts/biome_config_validator.py deprecated biome.json
# Validate structure only
python3 scripts/biome_config_validator.py validate biome.json
# JSON output
python3 scripts/biome_config_validator.py lint biome.json --format json
# Summary only
python3 scripts/biome_config_validator.py lint biome.json --format summary
Rules (22)
Structure (5)
- Invalid JSON syntax
- Unknown top-level keys
- Invalid schema version ($schema URL)
- Missing recommended sections (linter, formatter)
- Invalid file patterns in includes/excludes
Linting (7)
- Unknown lint rule names
- Rules in wrong category
- Conflicting rules (e.g., useConst vs noConst)
- Disabled recommended rules without justification
- Invalid rule severity values
- Empty rule groups
- Deprecated rule names
Formatting (5)
- Invalid indent style/width combination
- Conflicting formatter settings
- Line width out of reasonable range
- Invalid quote style values
- Tab width mismatch with indent width
Best Practices (5)
- Missing VCS integration settings
- Overly broad ignore patterns
- No organizeImports configuration
- Missing JavaScript/TypeScript specific settings
- Extends pointing to non-existent config
Output Formats
- text (default): Human-readable with colors and severity icons
- json: Machine-readable with file, rule, severity, message
- summary: Counts by severity only
Exit Codes
- 0: No issues (or warnings only)
- 1: Errors found
- 2: Invalid input
Usage Guidance
This skill is internally coherent for validating biome.json files: it reads the target file and local paths referenced by 'extends' and reports issues. Before installing or running, review the entire scripts/biome_config_validator.py file (the prompt contained a truncated excerpt) to confirm there are no network calls, subprocess executions, or code that transmits data. Run it first in a sandbox or on non-sensitive repositories. Be aware that the validator will attempt to access local files referenced by the config (e.g., extends paths), so avoid running it on directories containing secrets unless you trust the script. If you want extra assurance, search the full script for imports or functions such as requests/urllib/socket/subprocess/os.system/open with remote URLs, or any code that writes out data to external endpoints, and verify those are absent or intentional.
Capability Analysis
Type: OpenClaw Skill
Name: biome-config-validator
Version: 1.0.0
The skill is a legitimate utility for validating Biome (biome.json) configuration files. The core logic in scripts/biome_config_validator.py performs static analysis of JSON structure, rules, and formatting settings using standard Python libraries without any network access, shell execution, or sensitive data access. The instructions in SKILL.md are strictly aligned with the tool's stated purpose.
Capability Assessment
Purpose & Capability
Name/description (Biome config validator) align with the included script and SKILL.md: the commands run a Python script that parses JSON and applies lint/structure/formatting/best-practice rules. No extraneous credentials, binaries, or unrelated capabilities are requested.
Instruction Scope
The SKILL.md instructs the agent to run the bundled Python script on a specified biome.json and choose output format/commands. The script logic shown operates on the provided file, checks schema, rule groups, patterns, and local 'extends' paths. It does not instruct reading arbitrary system state or network endpoints. Note: the script checks existence of 'extends' paths and will examine local filesystem paths referenced by the config (expected for a validator).
Install Mechanism
No install spec; this is instruction-only plus a bundled Python script. No downloads, package installs, or external installers are present in the provided metadata.
Credentials
The skill declares no environment variables, no credentials, and no config paths. The script as shown only reads files passed on the command line and local paths referenced by the config; it does not require secrets or external tokens.
Persistence & Privilege
The skill is not always-enabled and does not request any persistent system-wide privileges. It runs only when invoked and does not modify other skills or agent-wide settings based on the provided content.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install biome-config-validator - After installation, invoke the skill by name or use
/biome-config-validator - Provide required inputs per the skill's parameter spec and get structured output
