The Tech Stack Detector Tool
Point it at a repository and it infers the languages, frameworks, package managers, and testing and build tooling in use — instant orientation for any agent or engineer meeting a codebase for the first time, on infrastructure you control.
Every new repo starts with "what is this built with?"
Before anyone can work in a codebase — or any agent can reason about it — they need to know the stack: the languages, the frameworks, how it’s tested and built. Figuring that out by hand is the slow first step every time.
Cold-start friction
Every unfamiliar repo begins with manual archaeology.
Tooling is implicit
How a project is tested and built lives in config no one reads first.
Agents need grounding
An agent can’t choose the right approach without knowing the stack.
Portfolios are opaque
Nobody has a current inventory of what each repo is built with.
Inferred stack, instantly
Detection
Languages and frameworks
What the code is written in.
The tool infers the primary languages and frameworks from the repository’s files and signals, giving an immediate, accurate read on what a project is built with.
- Language inference
- Framework detection
- Package-manager identification
- Per-ref analysis
Languages + frameworks
Tooling
Testing and build setup
How it’s tested and shipped.
It also detects testing and build tooling, so an agent knows how to run, test, and build the project before it tries — the difference between a useful action and a failed one.
Test + build
Governance
On-premise analysis
Source stays internal.
Detection runs against a snapshot inside your perimeter with audit logging, so stack inventory never exposes code.
IP-safe, logged
Parameters
The detect_tech_stack tool accepts these inputs when an agent calls it. Required inputs are flagged.
Where stack detection pays back
Onboarding
Tell a new engineer exactly what a repo is built with.
Agent grounding
Let an agent pick the right approach for the stack.
Portfolio inventory
Build a current map of stacks across many repos.
Build setup
Discover the test and build commands automatically.
Migration scoping
Assess what a migration off a framework involves.
Documentation
Seed a README or architecture doc with the real stack.
Assigned to agents, orchestrated as networks
On VDF AI, an industry’s use cases map to agents, and you assign tools like this one to those agents. Compose multiple agents into a governed, on-premise network.

Questions about the Tech Stack Detector tool
What does the tech stack detector do?
It infers the languages, frameworks, package managers, and testing and build tooling a repository uses, giving instant orientation on an unfamiliar codebase. Assigned to an agent, it grounds the agent in how the project is actually built.
Why does an agent need it?
An agent can’t choose the right approach — or run the right test and build commands — without knowing the stack. Detection turns guesses into correct actions.
Does it analyze a live repo?
It analyzes a snapshot at a given ref, so results are stable and reproducible.
Is our code exposed?
No. Detection runs on-premise with audit logging; source never leaves your perimeter.
How does it pair with other tools?
It feeds the README, API-docs, and architecture-doc generators and the repository map, which all benefit from knowing the stack up front.
