The in-app AI agent shipped all ~41 tool schemas on every model step. This adds a two-tier catalog: core tools (frequent or one-line) stay always-active; the rest are advertised as a compact catalog and their full schema is fetched on demand via the loadTools meta-tool, wired through ai@6 prepareStep's per-step activeTools. - tools/tool-tiers.ts: CORE_TOOL_KEYS, INLINE_TOOL_TIERS, applyLoadTools, catalog builders (+ tool-tiers.spec.ts, 13 cases). - ai-chat.service.ts prepareAgentStep: returns activeTools = [...CORE_TOOL_KEYS, loadTools, ...activatedTools]; per-turn activated Set. - ai-chat.prompt.ts: buildToolCatalogBlock renders the deferred catalog. - mcp/tool-specs.ts: tier + catalogLine metadata (external snake_case /mcp transport unchanged). - EnvironmentService.isAiChatDeferredToolsEnabled(): AI_CHAT_DEFERRED_TOOLS, default ON per issue intent (kill-switch =false restores old behavior). Gate: server ai-chat 631/631, tool-tiers 13/13, mcp 472/472, tsc clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
