SDKs

A CLDK SDK (a frontend) is an ergonomic analysis API over the canonical JSON that the codeanalyzer backends produce. Because the backends do all the language analysis, every SDK inherits every backend for free: the same call graphs, symbol tables, and reachability, exposed through the idioms of your language.

This is the frontend layer. For the analyzers behind it, see the backends overview.

Frontends (SDKs)

The SDK you write against. Each is an ergonomic analysis API over the canonical JSON.

SDK	Repository	Maturity
Python	codellm-devkit/python-sdk	Mature
TypeScript	codellm-devkit/typescript-sdk	Alpha
Java	Not started	Help wanted Stub
Rust	Not started	Help wanted Stub
Go	Not started	Help wanted Stub

Pick an SDK

Python SDK The reference implementation. Stable and the most complete: install cldk from PyPI and query Java, Python, and TypeScript projects through one analysis facade.

TypeScript SDK Experimental (alpha). A TypeScript/Node frontend over the same canonical analysis JSON. Track progress on GitHub.

Add a frontend Help wanted. A new frontend inherits every backend for free; see the roadmap and starting points for a native SDK.

Adding a language pack

A CLDK skill scaffolds a whole new language (a codeanalyzer-<lang> backend plus the SDK bindings) end to end. See codellm-devkit/developer-skillset.

Same contract, every language

Each SDK speaks the same analysis vocabulary because they all read the one schema the backends serialize:

• CLDK(language=...).analysis(project_path=...) to construct the facade.
• The core methods (get_symbol_table, get_call_graph, get_callers, get_callees, and friends) return the same typed models.
• Adding a backend lights the new language up across every SDK at once.

The Python SDK is stable and the place to start. The TypeScript SDK is experimental and evolving. The Java, Rust, and Go frontends are unbuilt: see Add a Rust frontend for the shape a native SDK takes.
