Hardcoded system prompts force frequent change_title tool calls causing unnecessary API requests with no user override option #43
Description
Current Behavior
The default system prompts are hardcoded in the codebase with mandatory instructions to call the change_title tool:
Claude Default Prompt:
happy-cli/src/claude/utils/systemPrompt.ts
Lines 7 to 9 in 39847c7
Codex Default First Prompt:
happy-cli/src/codex/runCodex.ts
Line 639 in 39847c7
Problems
- Unnecessary API Request Overhead
- Claude is instructed to ALWAYS call mcp__happy__change_title at the start of every new chat
- Claude is further instructed to call it multiple times whenever the title needs updating
- Each tool call results in an additional API request that consumes credits/quota
- For high-volume users, this results in significant unnecessary API consumption
- No User Override Capability
- The prompts are hardcoded directly in the source code
- Users have no way to disable or modify this behavior without editing the source code
- No configuration file, environment variable, or settings option exists
Impact
- Mandatory Costs: All users pay for these API calls regardless of whether they want the feature
- No Control: Users cannot opt out or customize the prompt behavior
- Wasted Resources: Unnecessary calls for users who prefer manual title management or don't use titles

All tokens are cached so it cost next to nothing. CC does itself too, but it is too buggy so we rolled our own.
