- Paginate through all tools from registry API (was limited to 20)
- Add 'Hide broken tools' checkbox (enabled by default)
- Filter out tools with BROKEN import or execution health
Some AI SDK tools (like @parallel-web/ai-sdk-tools) expect execute(params, context)
where context contains { abortSignal, messages, toolCallId }. Previously we only
passed params which caused 'Cannot destructure abortSignal' errors.
Also:
- Improved playground system prompt for better tool execution
- Playground /api/tools now proxies to web app with response transformation
- Added broken-tools.md documenting tool failure categories

- Add AbortController timeout (120s) to Railway fetch requests
- Gracefully handle timeout errors and report to health check system
- Increase /api/chat maxDuration from 60s to 300s (5 minutes)
- Prevents entire chat from timing out when one tool has large dependencies
- Tools that timeout are logged and skipped, allowing others to load
Fixes issue where tools like ctx-zip with many dependencies would
cause the entire chat request to timeout after 60 seconds.

Added error, warning, success, and info color CSS variables to
playground globals.css so that Badge component variants display
with correct colors. The error variant will now show red as expected.

PROBLEM:
DefaultChatTransport body is cloned ONCE on mount, so env vars
were always empty {} even after localStorage loaded them.
SOLUTION:
Use a function for body instead of an object. AI SDK v6 calls
body() on each request, ensuring latest env vars are sent.
Changes:
- useChat.ts: body: { env } → body: () => ({ env: buildEnvObject() })
- buildEnvObject() is called fresh on each request
- Env vars now sent correctly to /api/chat

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

with tool() from AI SDK always have an execute method. Added non-null assertion
with biome-ignore comment to fix the TypeScript build error.

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:**
