Major changes to the TPMJS specification:
1. Auto-Discovery: The `tools` array is now optional. If omitted, TPMJS
automatically scans package exports and registers any export with
`description` and `execute` properties (standard AI SDK tool format).
2. Renamed `exportName` to `name` in tool definitions for cleaner spec.
3. Added `/list-exports` endpoint to Railway executor that:
- Lists all exports from a package
- Identifies valid AI SDK tools
- Extracts descriptions for auto-discovered tools
4. Added `toolDiscoverySource` field to track 'auto' vs 'manual' discovery.
5. Updated tool page UI with:
- Auto-discovery warning banner
- Badge showing discovery source
6. Updated all documentation pages (docs, spec, publish) to reflect:
- Optional tools array with auto-discovery
- Use of `name` instead of `exportName`
- Auto-extraction of schema and description

- Add TTL-based module cache (2 minutes) for imported esm.sh packages
- Cache non-factory tools to avoid re-downloading on each request
- Factory functions are cached but always re-imported to get fresh env vars
- Automatic cleanup of expired cache entries every minute
- Enhanced /cache/stats endpoint shows TTL info and expiration times
- Executor now updates TPM.js database directly when loading tools
- Update /api/tools/update-schema to use packageName+exportName lookup
- Remove schema update logic from HLLM proxy (no longer needed)
- Move env var injection to happen BEFORE cache check and factory function calls
- This ensures process.env is set when factory functions like Valyu's webSearch() read from it
- Skip caching factory-created tools since they may read env vars at creation time
- Fixes issue where Valyu tools fail with 'VALYU_API_KEY is required' even when key is provided
Same issue as startTime - these variables were destructured inside the
try block but referenced in the catch block for health reporting. If
JSON parsing or any early error occurred, the catch block would crash
with 'packageName is not defined'.
Now declares them with 'unknown' defaults before try, then assigns
the actual values inside.
The startTime variable was declared inside the try block but referenced
in the catch block, causing 'startTime is not defined' errors when
exceptions occurred before line 404 (e.g., during req.json() parsing).
Moving the declaration before the try ensures it's in scope for the
catch block's executionTimeMs calculation.
Health status is now reported from the executor - the single point where
all tools run. This ensures consistent health tracking regardless of
client (playground, direct API, etc).
- Add reportToolHealth() to Railway executor
- Report success/failure after every tool execution
- Remove health reporting from playground (executor handles it)
- Executor calls /api/tools/report-health which has all the logic
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

- Set DENO_DIR=/app/.deno_cache to persist module cache
- Pre-cache common dependencies (zod-to-json-schema, ai, zod) during build
- Add Railway volume configuration for /app/.deno_cache
- Improve logging to show cache hits vs network downloads
- Add --allow-read and --allow-write permissions for cache access
This dramatically reduces tool loading time after the first import.
Dependencies are downloaded once and reused across all subsequent requests.
Example: ctx-zip with 200+ dependencies will only download once instead
of on every chat request.

Add sanitizeJsonSchema() function to fix common schema issues:
- Replaces invalid type 'None' (common in Python tools) with 'object'
- Ensures all schemas have a valid type field
- Recursively sanitizes nested schemas in properties, items, anyOf/oneOf/allOf
- Prevents OpenAI API errors from malformed tool schemas
This fixes the error with @superagent-ai/ai-sdk guard tool which
returns type: 'None' instead of a valid JSON Schema type.

Added Strategy 2.5 to schema extraction to handle AI SDK v6's
jsonSchema() wrapper which uses `.jsonSchema` property instead
of `.schema`.
This fixes schema validation errors for @tpmjs/hello and other
packages that use jsonSchema() wrapper.
Error was: "No valid schema found" with keys ["_type", "jsonSchema", "validate"]
Fix: Check for inputSchema.jsonSchema as an object property

The Node.js compatibility layer (npm: specifier) broke environment
variable passing because tools imported via npm: expect process.env,
not Deno.env.
Root cause: Recent commit added npm: specifier for Node compatibility,
but env injection code only set Deno.env.set(), not process.env.
Fix: Set environment variables in BOTH locations:
- Deno.env.set() for esm.sh imports
- globalThis.process.env for npm: imports
This restores functionality for tools like Firecrawl that require
API keys via environment variables.
Fixes regression from commit 8562eb5.

Add multi-strategy import system to support Node.js packages in Deno:
1. Primary: Use npm: specifier for Node.js compatibility mode
2. Fallback: Use esm.sh with explicit esnext target
This allows packages like ai-sdk-tool-code-execution that depend on
Node.js built-ins (node:sqlite, undici) to work in the Deno runtime.
Also added deno.json with nodeModulesDir and BYONM support.

Detects and handles tools exported as factory functions that require
configuration before returning the actual AI SDK tool object.
Supports multiple factory patterns:
1. No-args factory: toolName()
2. Config object: toolName({ apiKey: 'xxx' })
3. Single-arg: toolName('api-key-value')
For config objects, tries multiple key name variations:
- Raw env vars: { VALYU_API_KEY: 'xxx' }
- Normalized apiKey: { apiKey: 'xxx' }
- Normalized key: { key: 'xxx' }
This enables dynamic loading of tools like @valyu/ai-sdk paperSearch
that use factory patterns instead of direct tool exports.

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

- 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:**
