Observations from codebase exploration: 5 verifiable gaps

[LifetimeVip]

After exploring the codebase, here are a few observations on concrete gaps that could be addressed.

Verified gaps (confirmed missing from current codebase)

1. Image input not passed through to models

• The provider schema (provider.ts) defines capabilities.input.image: true/false and many supported models (Claude, Gemini, GPT) support image input
• However, the agent loop (agent.ts) and tool layer (tool/) do not handle image/paste input from users
• Users can describe visual issues but cannot attach screenshots, error dialogs, or UI mockups

2. No user-facing reasoning budget control

• The provider schema tracks capabilities.reasoning: boolean and the Interleaved type handles reasoning content display
• But there is no config option or UI control to set thinking budget for models that support it (Claude 3.7 Sonnet, etc.)

3. Web search has no built-in search API integration

• websearch.ts is ~2.5KB and wraps a configurable backend
• No built-in Google/Bing/SearXNG integration — users must configure an MCP tool or external service

4. Only Zed editor extension exists

• packages/extensions/ contains only a Zed extension
• No VS Code extension, though the HTTP API server (server/) already exposes all needed endpoints

5. @file/@folder mention autocomplete not present

• No mention syntax or file autocomplete in the prompt input component

These are observations from reading the code, not feature requests. Happy to help with any that the team considers worth addressing.

This issue doesn't fully meet our contributing guidelines.

What needs to be fixed:

• No issue template was used. All issues must use one of the three templates: Bug Report, Feature Request, or Question
• This issue bundles 5 separate topics into one report. Each should be filed as its own issue using the appropriate template
• Feature requests must have titles starting with [FEATURE]: and include the required verification checkbox
• The issue reads as an AI-generated codebase audit, which is not an accepted issue format

Please edit this issue to address the above within 2 hours, or it will be automatically closed.

This issue might be a duplicate of existing issues. Please check:

• [FEATURE]:Official - OpenCode VS Code extension #11176: Official VS Code extension feature request (Gap 4 — VS Code extension)
• @ is not listing the available files #6618: @ file mention not listing available files (Gap 5 — @file autocomplete)
• [FEATURE]: Support for disabling adaptive thinking on Opus/Sonnet 4.6 (equivalent to CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING) #22797: Feature request for reasoning/thinking budget control (Gap 2 — reasoning budget)

If you believe this was flagged incorrectly, please let a maintainer know.
