A new server you create. It is not this listing's official endpoint. Use the publisher install when you want their URL and their credentials.

DiffSense

DiffSense is a Change Risk Gate for the PR stage: it evaluates whether the current diff introduces regression risks without performing full codebase scans or style checks. Designed for minimal alerts, high precision, low latency, and interpretable results.

Quick Start

ScenarioAction
GitHub Pull RequestCopy the workflow from diffsense/docs/quickstart.md (Method 1) to .github/workflows/diffsense.yml in your target repository. Uses the default GITHUB_TOKEN with no additional configuration required. After committing and creating/updating a PR, the workflow will automatically execute the audit and post results under the PR.
Local AuditRun pip install -e diffsense in the repository root, or pip install "git+https://github.com/GoldenSupremeSaltedFish/DiffSense.git@main#subdirectory=diffsense", then execute diffsense replay <path-to-diff>.
Agent / LLM IntegrationInstall the MCP server with pip install "diffsense[mcp]" and run diffsense-mcp, or consume the JSON contract / SARIF directly. See Agent Integration Guide.

Complete steps are available at diffsense/docs/quickstart.md.

Optional: Add .diffsense.yaml to your repository root to use the officially recommended configuration, suitable for most teams.

Features

  • CI / Local: Performs semantic risk auditing on MR/PR diffs, outputting review_level and recommended actions. Analyzes only changed content without slowing down pipelines. Low-quality rules are automatically downgraded. Does not automatically modify CI status; decisions to block are made manually or by downstream processes.
  • Agent / LLM Integration: Deterministic, machine-readable surfaces for agents and CI gates β€” versioned JSON contract (schema_version), SARIF 2.1.0 output, and a read-only MCP server (audit_diff / audit_replay / list_rules / explain_rule). See the Agent Integration Guide and CLI Contract.
  • VSCode Extension: Maintained in the vscode-extension directory of this repository (dual-artifact layout). Install from the Marketplace or download the VSIX from Releases.

Quick Start (Detailed)

GitHub Actions

Copy the complete YAML from diffsense/docs/quickstart.md (Method 1) to your repository's .github/workflows/diffsense.yml to enable PR auditing.

GitLab CI

  1. In your project, go to Settings β†’ CI/CD β†’ Variables and add the variable DIFFSENSE_TOKEN (Personal Access Token with api permissions; recommended to check Mask variable).
  2. Add the corresponding job to .gitlab-ci.yml. See the example at diffsense/gitlab-ci-example.yml.

VSCode Extension

Maintained in the vscode-extension directory of this repository. Install from the Marketplace or download the VSIX from Releases.
