4 use cases

  • Find the symbols behind a bug question before editing

    Ask a plain bug question and get the ranked code symbols that answer it.

    View prompt
    Using the bgts-context-engine repository, index the repository at <target repo path> with bce index, then run bce context with the bug description <bug description> as the task. Expected output: a ranked list of symbols with a coverage report. Verify that the top results include the function that sets the behaviour named in the bug.

  • Let a coding agent pull ranked context over MCP

    Connect an MCP-capable coding agent to the code graph so it asks before it searches.

    View prompt
    In the bgts-context-engine setup, make sure the repository at <target repo path> is indexed, then start the MCP server with bce serve-mcp and connect the agent to it over stdio. Expected output: the agent gets a ranked answer for the task <task text> before any grep or glob call. Verify that the agent's first tool call is to the context tool and that the returned symbols include the files the task changes.

  • Replay a retrieval call to audit a bad agent change

    Re-run the exact context an agent received and check which stage surfaced the wrong symbol.

    View prompt
    Using the bgts-context-engine repository, index <target repo path> at the commit <commit id>, then run bce context with the task <task text> and the flag --no-select. Expected output: the byte-exact context pack. Verify by running the same command again and confirming the output matches.

  • Trace React Native calls into native Swift, Kotlin or Objective-C

    Find the native method behind a NativeModules call in a React Native or Expo app.

    View prompt
    Using the bgts-context-engine repository, index the React Native app at <target repo path>, then run bce context with the task <question about a NativeModules call>. Expected output: a ranked answer that includes the native Objective-C, Swift or Kotlin method. Verify that the native method is linked from the TypeScript call site.

How to use BGTS Context Engine

  1. Check you have what it needs: Docker with Docker Compose, to run PostgreSQL 16 with Apache AGE and pgvector; Python with pip; A local repository to index.
  2. Open bgts-ai-org/bgts-context-engine on GitHub and read the README and license.
  3. docker compose -f deploy/docker-compose.yml up -d
  4. pip install bgts-context-engine
  5. cp .env.example .env
  6. bce migrate

These steps come from our top use case, Find the symbols behind a bug question before editing, which also has a copy-paste agent prompt.
