Tools (5)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • impact_preview

    Predicts the blast radius of a proposed CSS change before it is made. Given a selector, property, and optional new value, returns every competing rule in the codebase that would be affected — showing which selectors will see a different value, which are shielded by higher specificity, which cascade relationships are uncertain, and which downstream rules are affected through CSS variable chains or inheritance. Works without a browser. Use this before making any CSS change to understand the full impact.

  • live_resolve

    Resolves CSS for a selector by querying a live running browser via Chrome DevTools Protocol (CDP). Returns exact computed styles and every matched rule in cascade order — no static analysis, no heuristics, confidence is always exact. Requires Chrome or any Chromium browser (Edge, Brave, Arc) running with --remote-debugging-port=9222. Use this when you need ground truth. Fall back to resolve_styles when no browser is running.

  • resolve_styles

    Resolves what CSS actually applies to a given selector. Returns every property the selector would receive, which rule wins for each property, and which rules were overridden — with confidence levels (certain/likely/possible) since no real DOM is available. Call this before modifying styles for an element to understand the full cascade context first.

  • style_manifest

    Builds a compressed, structured summary of a project's entire CSS knowledge — selectors, properties, variables, competition groups, and risk hotspots — that an agent can load ONCE at the start of a session and keep in context. Use this at the beginning of any CSS editing task to understand the landscape before querying individual selectors. Much faster than running resolve_styles on every selector. Follow up with resolve_styles, trace_property, or impact_preview for deep analysis of specific selectors surfaced in the manifest.

  • trace_property

    Traces a CSS property across all provided files — finding every rule that sets it, grouping competing rules that target overlapping selectors, and showing who wins in each group. Use this to understand the blast radius of a property before changing it, or to find out why a property value isn't applying as expected.
