Generate a valid SKILL.md with YAML frontmatter for Claude Code, Copilot, Codex and other Agent Skills compatible agents.

Validate a SKILL.md file against the Agent Skills specification: frontmatter, name format, description length and body size.

Build a robots.txt that allows or blocks GPTBot, ClaudeBot, PerplexityBot, Google-Extended and other AI crawlers separately for training and search.

Build an Agent2Agent (A2A) Agent Card JSON for /.well-known/agent-card.json with skills, interfaces, capabilities and security.

Validate an A2A Agent Card against required fields, interface bindings, skills and capabilities for versions 1.0 and 0.3.

Check an llms.txt file for the required H1, blockquote summary, sections and link format, so AI tools can read your site.

Lint an MCP tool definition and validate sample arguments against its inputSchema before you ship your server.

Convert an OpenAPI 3 document (JSON or YAML) into MCP tool definitions with inputSchema, annotations and HTTP hints.

Decode TOON (Token-Oriented Object Notation) back into JSON, with strict array-length and table-row validation. Also converts JSON to TOON.

Paste a JSON payload and compare the estimated token count of pretty JSON, compact JSON and TOON to see how much a prompt would shrink.
