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
- Remove direct DB updates from playground
- Add /api/tools/report-health endpoint with all health logic
- Playground now reports results to web app API
- All env var / validation error detection is in one place
- Health status updates based on execution success and error type
- Fix type errors with proper null checks
The executor returns HTTP 500 for all tool errors, including missing env vars.
Before: 500 response = BROKEN
After: Check error message for env/validation patterns before marking BROKEN
This ensures tools that require API keys (like @parallel-web/ai-sdk-tools)
show importHealth: HEALTHY since the tool loads correctly - it just needs config.
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

Removes importHealth, executionHealth, healthCheckError, and lastHealthCheck
fields from tool search results. Models were refusing to call tools marked
as BROKEN, even when the issue was just a missing env var.

Simplify execution health check logic:
- If executor responds (2xx or 4xx), tool is HEALTHY
- Only mark BROKEN for 5xx errors or network/timeout failures
- Validation errors (URL format, missing fields) mean tool IS working
- Remove brittle pattern matching for specific error messages
The previous approach tried to match specific error patterns to determine
if an error was "acceptable". This was fragile. The new approach:
- Import check: can we load and describe the tool?
- Execution check: did the tool execute at all?
If a tool throws a validation error, it executed successfully - it's
correctly rejecting invalid test input. Only infrastructure failures
(executor down, network timeout) indicate a truly broken tool.
Tools that reject invalid test inputs (like invalid URLs) are actually
working correctly - they're validating input as expected. Previously
the health check marked these as BROKEN because the test used dummy
values like 'test' which failed Zod validation.
Now input validation errors (invalid URL, invalid format, type mismatch,
etc.) are treated as HEALTHY, similar to how we already treat missing
environment variables.
When a tool is marked as BROKEN but executes successfully in the
playground, update its health status to HEALTHY. This ensures
stale health check data doesn't persist when tools are working.
Also fixes noImplicitAnyLet lint error by refactoring to const.
