LABSCO SUMMARY

One tool, one question, and the repository does not have to be yours.

ask_repo takes a repo, a prompt and optionally a ref, and that is the entire surface — there is nothing to configure and nothing else to call. The examples it ships with aim at understanding rather than change: how a server handles concurrent connections, how an API is meant to be used. Nothing here writes to a repository or opens a pull request, so the output is an answer you act on yourself.

What it is

A single-tool server that takes a repository, a question and an optional ref, and answers from the code it finds there.

What you get

A question answered against a repository named as owner/name — nginx/nginx, hashicorp/terraform
A ref accepted alongside the question, so the answer is read from that revision rather than whatever is current
Architecture questions of the kind the tool's own examples put — how nginx handles concurrent connections, walking the event loop, worker process model and connection state transitions
Integration questions put to a library's own source rather than to its documentation

Requirements

The owner and name of a Git repository you want to ask about, and the question to put to it — no account or key is set up for this server.

Setup effort

One command — npx -y instagit@latest

See installation options

USE CASES

01

Getting your bearings in a dependency you did not write

Point it at the dependency's repository and ask how a subsystem actually works; the example the tool ships with walks nginx's event loop, worker process model and connection state transitions.

ask_repo

02

Checking how a library is meant to be called before you copy an example

Pin ref to the revision you actually depend on and ask the integration question there, so the answer comes from that version of the source rather than from a blog post about a different one.

ask_repo

1 tool

Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.

`ask_repo`

Analyze any Git repository with AI. Point it at a repo and ask questions about the codebase.

Example prompts by use case:

Understanding Architecture:

repo: "nginx/nginx", prompt: "How does nginx handle concurrent connections? Walk through the event loop, worker process model, and connection state transitions."

Integration and API Usage:

repo: "hashicorp/terraform", prompt: "How do I implement a custom provider? What interfaces does the SDK expose, how are CRUD operations mapped to the resource lifecycle?"

Debugging and Troubleshooting:

repo: "docker/compose", prompt: "How does Compose resolve service dependencies and startup order? What happens with depends_on and health check conditions?"

Security Review:

repo: "redis/redis", prompt: "Review the ACL security model. How are per-user command permissions enforced, and how does AUTH prevent privilege escalation?"

Code Quality and Evaluation:

repo: "vitejs/vite", prompt: "How does Vite's plugin system compare to Rollup's? What are the Vite-specific hooks and tradeoffs?"

Deep Technical Analysis:

repo: "ggml-org/llama.cpp", prompt: "How does the KV cache work during autoregressive generation? How are past key-value pairs stored, reused, and evicted?"

Migration Planning (with ref — Pro/Max plans only):

repo: "mui/material-ui", ref: "v4.12.0", prompt: "Document the Button component's full API surface — every prop, its type, default value, and behavior."
repo: "mui/material-ui", ref: "v5.0.0", prompt: "Document the Button component's full API surface — every prop, its type, default value, and behavior." (Compare both results to build a migration guide between v4 and v5)
repo: "kubernetes/kubernetes", ref: "release-1.29", prompt: "How does the scheduler's scoring and filtering pipeline work for pod placement?"

Ask detailed, specific questions — the tool returns real function signatures, parameter types, return values, and source citations with exact file paths and line numbers.

If you hit a rate limit (429), the user's monthly token credits are exhausted — they can wait for the reset or upgrade their plan. Free-tier repos larger than 2 GB will be rejected with a 413 error; suggest upgrading to Pro or Max for unlimited repo size.

BEFORE YOU INSTALL

What to know first

Tools you get

1 tool when we connected. Everything in the use-case list is ask_repo with a different prompt. Without a key it registers an anonymous token; INSTAGIT_API_KEY only raises rate limits and speed.

Requires

npx on PATH
Node.js 18+
