PROBLEM:
- Tool wrappers cached env vars in closure, so cached tools used stale env
- Client env vars weren't reaching Railway executor even when provided
- No visibility into env var flow through the system
SOLUTION:
1. Store env vars per conversation in conversationEnv Map
2. Tool execute functions look up latest env from Map (not closure)
3. Chat API calls setConversationEnv() on each request
4. Added logging at every step

- Change search-registry to use /api/tools instead of /api/tools/search (not deployed yet)
- Add client-side filtering for search queries since deployed API doesn't support search
- Handle both deployed (/api/tools) and local dev (/api/tools/search) response formats
- Remove lint from pre-commit hooks to speed up commits (keep format + type-check)
- Fixes 404 errors when playground tries to search tools in production

- Try Zod v4 toJSONSchema() or jsonSchema() first
- Fall back to AI SDK jsonSchema.schema property
- Fail gracefully with detailed debug info
- Supports both Zod-based and jsonSchema-based tools
THE BREAKTHROUGH: AI SDK v6 tools use jsonSchema() which wraps plain JSON Schema objects, NOT Zod schemas. JSON Schema is fully serializable.
Changes:
1. Railway server: Extract raw JSON Schema from toolModule.inputSchema?.schema
2. Playground loader: Wrap received JSON Schema with { type: 'json_schema', schema: ... }
3. This matches AI SDK v6 format exactly - no Zod serialization needed
How it works:
- Tools define inputSchema: jsonSchema({ type: 'object', properties: {...} })
- AI SDK stores it as { type: 'json_schema', schema: {...} }
- Railway extracts the plain JSON Schema (.schema property)
- Sends it as plain JSON (fully serializable)
- Playground wraps it back in AI SDK format
- OpenAI receives valid JSON Schema for function calling
This fixes both errors:
✅ No more "def.shape is not a function" (not using Zod)
✅ No more "Invalid schema type None" (proper JSON Schema provided)
Note: Tools using Zod instead of jsonSchema() will need to migrate.
TPMJS standard: All tools MUST use jsonSchema() with plain JSON Schema.

Implements a complete dynamic tool loading system that allows the playground to discover and load tools from the TPMJS registry at runtime.
**Architecture:**
- Search tool package (@tpmjs/search-registry) - Searches registry for tools
- Search API endpoint (/api/tools/search) - Text-based search with scoring
- Pre-flight tool loading - Automatically searches and loads tools on every message
- Railway executor service (Deno) - Loads tools from esm.sh via HTTP imports
- Dynamic tool loader - Calls Railway to load and execute tools remotely
**Key Components:**
1. Railway Executor (apps/railway-executor/)
- Deno-based service that natively supports HTTP imports
- Endpoints: /load-and-describe, /execute-tool, /cache/stats, /cache/clear
- Deploys to Railway with deno run --allow-net --allow-env server.ts
2. Search Tool Package (packages/tools/search-registry/)
- AI SDK v6 tool for searching TPMJS registry
- Uses jsonSchema + inputSchema pattern
- Searches /api/tools/search endpoint
3. Search API (apps/web/src/app/api/tools/search/)
- Text-based search with composite scoring
- Scores: text relevance + quality boost + download boost
- Returns tool metadata with importUrl for dynamic loading
4. Dynamic Tool Loader (apps/playground/src/lib/dynamic-tool-loader.ts)
- Calls Railway service to load tools from esm.sh
- Creates tool wrappers that execute remotely
- Process-level module cache + per-conversation tracking
5. Pre-flight Loading (apps/playground/src/app/api/chat/route.ts)
- Automatically searches for tools on every user message
- Loads top 5 matching tools before agent processes request
- Merges with static tools for seamless experience
**Technical Decisions:**
- Deno over Node.js: Native HTTP import support without flags
- Remote execution: Tools run in Railway sandbox, not Vercel
- Pre-flight loading: Better UX than two-turn search pattern
- Text search: BM25 had dependency issues, simple scoring works well
**Environment Variables:**
