feat: Added ui to support input params for task creation

Added task parameters drop down in the UI

Clicking drops down into a json input

input is passed as additional params to task creation backend call

Task Params only available when task is initialized, the ui disappears with subsequent chat messages.

Greptile Summary

• Adds a collapsible "Task Parameters" JSON editor above the prompt input that only renders when no task is active (!taskID && !isDisabled), allowing users to inject extra key-value pairs into the createTask API call.
• The extra params are spread before description/content so core fields always win over user-supplied JSON.
• The feature is missing a process.env.NODE_ENV === 'development' guard on both the UI panel and the parse logic, making it available in all environments despite the stated dev-only intent.

Confidence Score: 4/5

Safe to merge with the dev-only guard added; without it, the feature ships to production contrary to design intent.

One P1 finding: the Task Parameters panel and its extraTaskParams injection are missing a NODE_ENV === 'development' check, exposing the feature in production. No P0 issues present.

agentex-ui/components/primary-content/prompt-input.tsx — needs dev-only environment guard on both the UI block and the extraTaskParams parse path.

Important Files Changed

Filename	Overview
agentex-ui/components/primary-content/prompt-input.tsx	Adds a collapsible Task Parameters JSON editor to the prompt input for injecting extra params on task creation, but the feature lacks a process.env.NODE_ENV === 'development' guard, making it visible and functional in all environments contrary to the stated design intent.

   setPrompt('') is called on line 122 before the extraTaskParams JSON parse. If the user's task-params JSON is invalid, the function returns early after showing the toast — but the main prompt text has already been wiped, causing silent data loss.

   Comment:
   `setPrompt('')` is called on line 122 **before** the `extraTaskParams` JSON parse. If the user's task-params JSON is invalid, the function returns early after showing the toast — but the main prompt text has already been wiped, causing silent data loss.

**Missing dev-only guard on Task Parameters UI**

The PR description says "Also only available in dev environment," but neither the UI panel (line 181) nor the `extraTaskParams` parse logic (line 126) has a `process.env.NODE_ENV === 'development'` check. As-is, the Task Parameters accordion and its ability to inject arbitrary JSON into `createTask` are fully live in production, directly contradicting the stated design constraint.
