Capability requirements for a skill.

This represents the parsed and normalized requirements from skill frontmatter.
Supports both Hermes/OpenClaw conventions and PraisonAI-specific extensions.

Attributes:
servers: Required MCP servers or service endpoints
tools: Required tool names (from tool registry)
env\_vars: Required environment variables (use sparingly)
openclaw\_hints: OpenClaw-specific metadata (passthrough)
fallback\_for\_tools: Tools this skill is a graceful fallback for. The
skill is offered only when *none* of these tools are present,
keeping capable agents free of redundant fallback guidance.
fallback\_for\_servers: MCP servers this skill is a graceful fallback
for. The skill is offered only when *none* of these servers are
present.
