Context before code

RepoMind is a task-first repository preflight for the moment before a coding agent or contributor changes unfamiliar code.

Give RepoMind a public GitHub repository and a specific change. It returns a cited task brief with files to inspect, risk boundaries to respect, and observed checks to run, plus a structured AGENTS.md and an evidence-aware repository map.

## Why it matters

The hardest part of working in an unfamiliar codebase is often not writing the patch. It is the orientation tax: finding the real entry point, learning local conventions, locating tests, and noticing fragile boundaries before the first edit.

RepoMind does not compete with an IDE assistant or write the patch. It gives Codex, Cursor, Claude Code, and human contributors a reviewable starting point so they can make a stronger first plan instead of wasting thousands of tokens.

## What happens during a preflight

RepoMind creates one bounded, read-only evidence pack from the public repository. Four specialists then review Architecture, Risk, Testing, and History.

In GPT-5.6 Native Mode, four independent GPT-5.6 Terra specialists use only bounded read-only tools: list_files, read_file, grep, git_log, and git_blame. A separate GPT-5.6 root reconciles only findings that survive the citation firewall.

A claim is withheld unless RepoMind can validate its repository path, exact line range, quoted source, and same-worker tool provenance. This keeps the handoff useful without asking developers to trust model narration blindly.

If credentials are unavailable, slow, or invalid, RepoMind visibly completes in deterministic Evidence Mode. The fallback is useful, but it never claims that GPT-5.6 ran.

## Built with Codex and GPT-5.6

I used Codex for repository exploration, architecture review, implementation, test design, failure-mode review, UI QA, documentation, and release validation.

At runtime, GPT-5.6 Terra performs the four independent source-grounded specialist reviews and root reconciliation. RepoMind's bounded cloning, citation firewall, artifact validation, partial-analysis disclosure, and deterministic fallback are application-enforced trust controls.

RepoMind gives coding agents context before code: less orientation tax, fewer blind edits, and a safer first plan.

Solo developer. I built the entire stack, including the React UI, the FastAPI backend, and the local MCP server. My biggest learning was that stopping hallucinations requires strict architecture, not just better prompts. Building the Citation Firewall taught me how to tightly bound GPT-5.6 Terra's tool calls and force the model to cryptographically prove its claims before accepting them. I also learned a massive amount implementing the new Model Context Protocol (MCP) to pipe this intelligence directly into local IDEs.
