Skill1 starsChanged 9 months agoMITView on GitHub

Curated WebMCP agent skill bundle for designing, implementing, operating, securing, evaluating, and maintaining page-local browser tools with agent-browser-style discovery, execution, observation, and verification. Use when building WebMCP integrations, connecting UI and UX state to agent actions, designing DESIGN.md workflows, or reviewing browser-agent safety and recovery.

The file

We split this skill into the rules it gives an agent

3 rules. About 0 are common, 1 is distinctive, and 2 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈1

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Use this bundle as the entrypoint for WebMCP work.

    line 9
  2. Distinctive:

    Prefer WebMCP tools when they cover the user goal.

    line 32
  3. Very specific:

    Use index.bs for normative behavior.

    line 36

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

webmcp-agents

Use this bundle as the entrypoint for WebMCP work. It keeps one page-local operating model while routing specialized work to the smallest relevant skill under skills/.

Route the request

  • webmcp-agent-browser — inspect, discover, execute, refresh, and verify like an agent browser.
  • webmcp-core — normative registration, discovery, execution, lifecycle, and cancellation.
  • webmcp-tool-design — tool schemas, UI↔UX journeys, state, confirmation, and recovery.
  • webmcp-declarative — exploratory HTML-form tools and preview behavior.
  • webmcp-frameworks — React, Angular, TypeScript, SSR, and lifecycle integration.
  • webmcp-design-md — DESIGN.md tokens, Lexer → AST → semantic model → Renderer workflows.
  • webmcp-security — origin, permissions, privacy, untrusted content, and consequential actions.
  • webmcp-evals — selection, chaining, outputs, reliability, and prompt-injection evaluation.
  • webmcp-service-workers — exploratory background routing and multi-tab architecture.
  • webmcp-setup — browser flags, origin trials, support checks, and fallback behavior.
  • webmcp-maintainer — source authority, validation, publication, and stale-content checks.

Shared operating loop

intent → observe live page → discover semantic tools → validate input
→ execute page-owned action → observe fresh state → verify result or recover

Prefer WebMCP tools when they cover the user goal. Keep DOM observation and direct browser actuation as explicit fallback and recovery primitives. Human-visible UI, accessibility, loading, errors, confirmation, cancellation, and agent results must remain one coherent journey.

Authority

Use index.bs for normative behavior. Treat the declarative API, service-worker material, and external DESIGN.md format as exploratory or version-gated unless the source says otherwise.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
