// guideCmd prints the Gortex reference guide — the same content served by the

// for shell use. The installed CLAUDE.md carries only the mandatory policy
// core and points here for everything else.

	Use:   "guide [topic]",
	Short: "Print the Gortex reference guide (providers, capabilities, tokens, analyze, search_ast, resources, workflow)",
	Long: `Prints the Gortex reference guide — the on-demand home for detail that is
not pre-paid in the installed CLAUDE.md: the LLM-provider matrix, the
non-obvious capabilities catalog, the token-economy deep-dive, the MCP
resources list, and the analyze / search_ast catalogs.

With no argument the full guide is printed with a topic index. Pass a topic
to print just that section:

  gortex guide providers
  gortex guide capabilities
  gortex guide tokens
  gortex guide analyze
  gortex guide search_ast
  gortex guide resources
  gortex guide workflow

The same content is served by the ` + "`gortex://guide`" + ` MCP resource
(section-addressable at ` + "`gortex://guide/{topic}`" + `).`,
