high confidence
✓
Purpose & Capability
Name/description (querying browser compatibility) match the SKILL.md: it only directs use of the caniuse CLI and provides feature-name mappings. Nothing requested (env vars, binaries, configs) is outside that purpose.
✓
Instruction Scope
Runtime instructions are narrowly scoped to checking for the caniuse binary and running `caniuse <feature>`, mapping user terms to caniuse feature names, and formatting results. The instructions do not ask the agent to read unrelated files, environment variables, or exfiltrate data.
✓
Install Mechanism
There is no install spec (instruction-only). The SKILL.md suggests installing `@bramus/caniuse-cli` via npm if missing, which is a reasonable, transparent recommendation rather than an automated download.
✓
Credentials
The skill requests no environment variables or credentials. The only implicit requirement is the availability of the caniuse CLI (or the ability to install it), which is proportional to the task.
✓
Persistence & Privilege
always is false and the skill has no install-time persistence or requests to modify other skills or system-wide settings. It does not require elevated or permanent privileges.
Assessment
This skill is a simple instruction-only wrapper for the caniuse CLI and appears safe and coherent. Before installing the suggested npm package yourself, verify you trust the package name (@bramus/caniuse-cli) and your environment's npm/global-install policy (global installs may require elevated privileges). Note that the agent will attempt to run shell commands (which is expected here); if you prefer, run `caniuse` locally and paste results instead of installing anything in a sensitive environment.

Like a lobster shell, security has layers — review code before you run it.

Browser Compatibility Query

Query browser compatibility data for web features using the caniuse CLI tool.

Prerequisites Check

Before querying, verify caniuse-cli is installed:

which caniuse || echo "NOT_INSTALLED"

If not installed, tell the user:

caniuse-cli is not installed. Install it with:

npm install -g @bramus/caniuse-cli

Querying Compatibility

Run the caniuse command with the feature name:

caniuse <feature-name>

Feature name formats:

  • Hyphenated: caniuse viewport-units
  • Quoted phrases: caniuse "viewport units"
  • With special chars: caniuse @property

Common feature name mappings (user term → caniuse query):

  • :has() selector → css-has
  • :where() selector → css-where
  • :is() selector → css-matches-pseudo
  • container queries → css-container-queries (size) or css-container-queries-style (style)
  • CSS nesting → css-nesting
  • subgrid → subgrid
  • aspect-ratio → css-aspect-ratio
  • gap in flexbox → flexbox-gap
  • CSS grid → css-grid
  • flexbox → flexbox

JS/API features:

  • ES modules → es6-module
  • async/await → async-functions
  • optional chaining → mdn-javascript_operators_optional_chaining
  • fetch API → fetch
  • service workers → serviceworkers
  • WebGPU → webgpu

Presenting Results

After running the command:

  1. Show the compatibility table as returned by caniuse

  2. Highlight key findings:

    • Which major browsers fully support it
    • Any browsers with partial support (note the limitations)
    • Browsers that don't support it at all

  3. Call out important notes if the output includes numbered notes (these often contain critical info about prefixes, flags, or partial implementations)

  4. Give practical advice based on the results:

    • If widely supported: "Safe to use in production"
    • If partial support: "Works but check the notes for limitations"
    • If poor support: "Consider a polyfill or fallback"

Handling Unknown Features

If caniuse returns "Nothing was found":

  1. Check the mapping table above — many features have specific caniuse names (e.g., :has() → css-has)

  2. Try common prefixes:

    • CSS properties: try css- prefix (e.g., css-grid, css-variables)
    • MDN data: try mdn- prefix for JS features

  3. Try variations:

    • Remove special characters: :has() → has or css-has
    • Use hyphens: "container queries" → container-queries

  4. If still not found, tell the user:

    This feature might not be in the caniuse database, or uses a different name. Check https://caniuse.com to find the correct feature name.
