- Stop marking a class's vulnerability-analysis agent failed when that agent succeeded and only reconciliation failed; the status tree now renders the analysis row completed and the exploitation row failed - Consume the worker's failedReconciliations signal in the CLI, which the mirrored PipelineState already declared but never read - Correct the class_reconciliation_failed message, which claimed the class's analysis results were still in the report when the class is excluded from it
Shannon is an autonomous, AI pentester for web applications and APIs.
It analyzes your source code, identifies attack paths, and executes real exploits to prove vulnerabilities before they reach production.
This package is Shannon Open Source: the full agent, run locally from your command line.
Quick Start
Prerequisites
- Docker: required for the worker container.
- Node.js 18+: required for the recommended
npxworkflow. - AI provider credentials: Shannon runs on Anthropic, OpenAI, xAI, AWS Bedrock, any other provider in the harness catalogue, and any endpoint that speaks the Anthropic Messages API or the OpenAI Chat Completions or Responses API through a custom base URL. You bring your own key, and Keygraph never proxies your model traffic. Shannon is provider-agnostic.
- Cyber safeguards cleared with your provider: Anthropic and OpenAI apply real-time safeguards to cyber-security workloads, which can interrupt a scan mid-run. Complete their guidance for legitimate security testers before your first run.
Run Shannon
Warning: Shannon actively executes exploits. Run it only against applications and environments you own or have explicit written authorization to test. Do not run Shannon against production systems.
# Configure credentials with the interactive wizard.
npx @keygraph/shannon setup
# Run a pentest against a source-available target.
npx @keygraph/shannon start -u https://your-app.com -r /path/to/your-repo
Shannon pulls the worker image from Docker Hub, starts the required local infrastructure, mounts the target repository read-only inside an ephemeral worker container, and writes results to a local workspace.
Editions
Shannon ships in two ways. Shannon Open Source is this package: the standalone pentester you run yourself, on demand, and complete in that lane. The Keygraph platform is the commercial product that runs an enhanced build of Shannon continuously and closes the full AppSec lifecycle around it - code analysis, finding management, automated remediation, verification, and enterprise deployment.
