Understand

Find stuff fast, even if you don’t
know what it’s called.

RepoQL gives your agent a map of the code and precise ways to read it. It can learn the local vocabulary, follow the implementation, and bring you back an explanation with sources you can check.

Your laptop

An authentication investigation: from unfamiliar names to where every request is checked, then a lesson saved for next time. Follow the workflow →

Follow the connections

Your system is bigger
than one checkout.

A change in one place can break a service in another. The answer is rarely in the code you have checked out.

Bring in the rest — other repositories, documents, git history, telemetry — and your agent can trace a change wherever it leads.

Bring another repository into reach →

Repos, folders, S3 buckets, lint reports, test coverage, and live telemetry, all through one host.

Remember why

The next agent should know
what this one learned.

Concepts are files you own, with reasons your team can read. Commit them with the repository so other sessions and teammates inherit them.

.repoql/concepts/rule/ConfigurationMigration.md

Example · a fictional codebase

Concept: ConfigurationMigration

Invariant

MyConfig is still in use but deprecated. Use MyNewConfig instead.

Why

MyNewConfig validates typed settings at startup, so missing or invalid values are caught before requests arrive. MyConfig remains for callers that haven’t migrated; adding new callers prolongs the migration.

Example

For a new retry timeout, add a typed setting to MyNewConfig rather than another string-key lookup through MyConfig.

Depth

Preserve configuration keys and defaults when migrating an existing caller.
Remove MyConfig only after its last caller has migrated.

Relevance

src/config/MyConfig.cssrc/config/MyNewConfig.cs

Verification

file:///src/config/MyConfig.cs;file:///src/config/MyNewConfig.cs;file:///src/**/*.cs;file:///tests/config/**/*Migration*.cs

During the investigation

Your agent saves what it learned.

RepoQL checks it against the evidence and saves it as Markdown.

During the next change

The next agent finds it in either file.

Its relevance covers both MyConfig and MyNewConfig.

As the code evolves

RepoQL notices when it goes stale.

When the last MyConfig caller migrates, a recheck fails and flags the concept for review.

Share the context

Give the team access
to the same understanding.

Not every agent runs beside a checkout. A code review bot, a Slack bot, a product manager asking “what if?” from their phone.

Uplink puts one RepoQL host, with your repositories and your team’s knowledge, within reach of all of them. It runs on your infrastructure and connects out, so there’s no port to open and no VPN to join.

How uplink works →

Your repositories and index stay on your host. Uplink relays authorised tool requests and results between the host and your agents.

Start with your own code

Bring a question you already care about.

Install RepoQL and connect the agent you already use. Open a repository and ask about your next change; the index builds as you go.

Then ask your agent

“Use RepoQL to investigate the change I’m about to make. What depends on it, and what should I know first? Show me the evidence.”

Judge the answer by what you can check: the code it cites and the reasons it finds.

Your existing agent

The installer connects RepoQL to Claude Code, Claude Desktop, Codex, Codex App, Cursor, GitHub Copilot, Amp, OpenClaw and OpenCode.

Clear data boundaries

The index lives on your host. Cloud features process selected content; the data guide explains what leaves and when.
