Browserslist Validator

Validate .browserslistrc files and browserslist entries in package.json for syntax errors, deprecated browsers, redundant queries, and best practices.

Commands

# Full validation (all rules)
python3 scripts/browserslist_validator.py validate .browserslistrc

# Validate browserslist in package.json
python3 scripts/browserslist_validator.py validate package.json

# Quick syntax-only check
python3 scripts/browserslist_validator.py check .browserslistrc

# Estimate coverage
python3 scripts/browserslist_validator.py coverage .browserslistrc

# Explain each query in human-readable form
python3 scripts/browserslist_validator.py explain .browserslistrc

# JSON output
python3 scripts/browserslist_validator.py validate .browserslistrc --format json

# One-line PASS/WARN/FAIL summary
python3 scripts/browserslist_validator.py validate .browserslistrc --format summary

# Strict mode (warnings become errors)
python3 scripts/browserslist_validator.py validate .browserslistrc --strict

# Target environment
python3 scripts/browserslist_validator.py validate .browserslistrc --env production

Rules (20)

#	Category	Severity	Rule
S1	Syntax	E	File not found or unreadable
S2	Syntax	E	Empty config (no queries)
S3	Syntax	E	Invalid query syntax / unknown browser name
S4	Syntax	W	Duplicate queries
B1	Browsers	W	Dead/deprecated browser (IE, Blackberry, etc.)
B2	Browsers	W	Browser with \x3C0.01% global usage
B3	Browsers	E	Browser version does not exist (e.g. Chrome 999)
B4	Browsers	E	Unknown browser name
Q1	Queries	W	Redundant query (covered by broader query)
Q2	Queries	W	Conflicting queries (e.g. `> 1%` and `\x3C 0.5%`)
Q3	Queries	E	`not dead` without any positive query
Q4	Queries	W	Empty result after `not` negation
C1	Coverage	W	Very low total coverage (\x3C80%)
C2	Coverage	W	Very high coverage (>99.5%, may include dead browsers)
C3	Coverage	I	No mobile browser coverage hint
C4	Coverage	I	No country-specific override detected
P1	Best Practices	W	IE queries present (recommend dropping IE)
P2	Best Practices	W	Unreasonably old versions (`last 20 versions`)
P3	Best Practices	W	`all` query used (too broad)
P4	Best Practices	W	Version pinning instead of range (`Chrome 90`)

Output Formats

text (default): Human-readable with [E]/[W]/[I] severity prefix
json: Machine-readable structured output
summary: Single-line PASS / WARN / FAIL

Exit Codes

0 — No errors
1 — Errors found (or warnings in --strict mode)
2 — File not found or parse error

安全使用建议

This skill appears to do exactly what it claims: a Python-based validator for browserslist configs. Before running: ensure you trust the source of the skill (it contains an executable script), have Python 3 available, and run the validator only on files you intend to analyze (it reads files you point it at). If you want extra assurance, open and review scripts/browserslist_validator.py locally (it contains no network calls or hidden endpoints in the provided content).

功能分析

Type: OpenClaw Skill Name: browserslist-validator Version: 1.0.0 The browserslist-validator skill bundle is a legitimate utility for auditing frontend browser targeting configurations. The core logic in scripts/browserslist_validator.py uses regex-based parsing and embedded datasets to validate .browserslistrc and package.json files without any network activity, external command execution, or sensitive data access. The SKILL.md instructions are well-defined and align strictly with the tool's stated purpose.

能力评估

✓ Purpose & Capability

Name/description (browserslist validation) matches the delivered assets: SKILL.md documents commands that run the included Python validator and there are no unrelated environment variables, binaries, or install steps requested.

✓ Instruction Scope

SKILL.md instructs the agent to run the included script against .browserslistrc or package.json. The script reads provided files and produces validation output; the instructions do not ask the agent to read other unrelated files, contact external endpoints, or exfiltrate data.

✓ Install Mechanism

There is no install spec (instruction-only skill + bundled script). No network downloads, package installs, or archive extraction are required.

✓ Credentials

The skill requires no environment variables, credentials, or config paths. The bundled script operates on local files supplied by the user (as expected for a linters/validator).

✓ Persistence & Privilege

always is false and the skill does not request elevated or persistent presence. It does not modify other skills or system-wide settings in the provided materials.

如何使用

安装完成后，直接呼叫该 Skill 的名称或使用 /browserslist-validator 触发
根据 Skill 的参数说明提供必要输入，即可获得结构化输出
