Description

Summary

packages/core/src/stores/room-store.ts — initConductor() concatenates agentCatalog (from gateway) and userMessage (from user input) directly into the conductor system prompt without any escaping, validation, or length limits.

let prompt = buildConductorPrompt(agentCatalog);
if (userMessage) {
  prompt += `\n\n---\nUser task:\n${userMessage}`;
}

Expected behavior

  • userMessage should be truncated to a reasonable max length
  • agentCatalog should be validated for expected structure before embedding
  • Consider wrapping user content in a fenced block to reduce injection surface

Files

  • packages/core/src/stores/room-store.ts — initConductor() (line ~97)
  • packages/shared/src/constants.ts — buildConductorPrompt()

Context

Introduced in PR #210.

Contributor guide

Research direction
Investigate how to sanitize or truncate userMessage and validate agentCatalog before embedding in the conductor prompt. Look into escaping or fenced blocks to prevent injection.
