Hindsight FAQs

Question 1

How does Hindsight integrate with my existing development tools?

Accepted Answer

Hindsight integrates seamlessly with VS Code and GitHub Copilot through MCP (Microsoft Copilot Protocol) tool calls. Once configured, Copilot can use Hindsight's tools to query your development history, test results, and chat sessions directly from the chat interface.

Question 2

What are the prerequisites for installing and using Hindsight?

Accepted Answer

To use Hindsight, you'll need VS Code v1.99+ with GitHub Copilot installed. For test ingestion capabilities, `cargo-nextest` is required. Hindsight itself is a Rust application installed via `cargo install hindsight-mcp`.

Question 3

What is Hindsight and what problem does it solve?

Accepted Answer

Hindsight is an MCP server that consolidates all your development data—Git logs, test results, and GitHub Copilot chat sessions—into a single, searchable database. It solves the problem of scattered information, allowing AI assistants to gain a comprehensive understanding of your project's context for more accurate and helpful responses.

Question 4

Can Hindsight help me with debugging and test failures?

Accepted Answer

Yes, Hindsight is highly beneficial for debugging. It links test results directly to specific Git commits, allowing you to use tools like `hindsight_failing_tests` to quickly identify what tests are failing and `hindsight_commit_details` to get context on the associated code changes, significantly streamlining your debugging process.

Question 5

What types of development data does Hindsight track?

Accepted Answer

Hindsight automatically ingests Git commit data (SHA, author, message, timestamp) and GitHub Copilot chat sessions (prompts, responses, attached files). It also tracks test run metadata, outcomes, durations, and failure output, especially when used with `cargo nextest`.
