// Zod-agnostic shared tool-spec registry consumed by BOTH the zod-v3 MCP server
// (packages/mcp/src/index.ts) and the zod-v4 in-app AI-SDK service
// (apps/server/src/core/ai-chat/tools/ai-chat-tools.service.ts). Intentionally
// imports NO zod: each consumer passes its OWN zod namespace into buildShape,
// because the two packages are on different zod majors (v3 here, v4 in the
// server) and a zod schema object built with one major cannot be reused by the
// other. The builders below only touch z.string()/.min()/.optional()/.describe(),
// z.array() and z.object() — API identical across v3 and v4 — so a single
// builder works with either namespace.
//
// Only tools whose snake_case/camelCase name, input schema AND model-facing
// description are genuinely identical across both layers live here. Tools that
// diverge on purpose (security guardrails, tuned UX, "Reversible" framing on
// some write tools, different limits, hybrid-RRF search, etc.) stay defined
// per-layer and are NOT represented here.
