/**
 * Host-neutral cross-tool routing guidelines for pi-exa.
 *
 * Two exports:
 *   - `PLANNER_GUIDELINES` is the shared per-tool guidance string for the four
 *     local `exa_research_*` planner tools; consumed by `tools.ts` and threaded
 *     onto each planner tool via `hostExtras.pi.promptGuidelines`.
 *   - `CROSS_TOOL_GUIDELINES` is the server-level decision tree consumed by
 *     the MCP server (`mcp-server.ts`) as `instructions`. It is intentionally
 *     duplicated as prose rather than synthesised from per-tool snippets so
 *     MCP clients see one self-contained routing block.
 *
 * Per-tool `promptSnippet` and `promptGuidelines` for the six Exa-API tools
 * live on the tool definitions themselves in `tools.ts` via
 * `hostExtras.pi.*` — bridgekit 0.9.0 threads them through to pi's
 * `registerTool` call without a sidecar map.

 * receive equivalent routing guidance to Pi's system prompt without
 * duplicating individual sentences.
