Keep your standards in AI-assisted development

Noema is a DeepSeek Harness plugin for developers who care about the code they ship. After each coding task, it shows complexity changes to help you decide which files and functions need a closer look

Review changes

Noema compares three metrics before and after each task:

Metric	What it measures
Cyclomatic complexity	Independent paths through the code
Cognitive complexity	Difficulty of following control flow, accounting for branches, nesting, and recursion
Maximum nesting depth	Deepest nesting of control structures within a function

Expand a file or function to locate changes within it. Its metrics include the code it contains; [Top Level] shows its own code separately from named child functions. Unchanged code is hidden by default and can be revealed when needed

These metrics help focus your review. Judge changes in the context of the code: a lower score alone does not mean better code

Analysis runs locally and compares the workspace at the start and end of each turn, including any manual edits made during that time. Results stay outside the model context

Supported languages

TypeScript (including TSX), Python, and Go are supported. JavaScript and TypeScript declaration files are excluded

No card appears when there are no supported code changes, including edits limited to comments or formatting. Code changes still appear when the scores remain the same

Install

Supports DSH ^0.1.7-rc.2 || ^0.2.0-rc.2 || ^0.2.1-alpha.1 and requires Node.js ^22.19.0 || >=24.0.0

Install the npm package into the Web profile, then start DSH:

dsh plugin --profile web add dsh-plugin-noema
dsh web

If DSH is already running, restart it and refresh the browser. Noema starts analyzing new turns after installation; ask DSH to modify a supported source file to try it

Choose files

Open Plugins → Noema → Files to analyze in the Web sidebar. Set include and exclude patterns relative to your workspace, such as src/** and **/*.test.ts, or use Add common test exclusions. Settings apply to the current Profile. Exclusions take precedence, and saved changes apply from the next turn

Noema respects .gitignore and excludes common dependency and build directories by default
