The open source taint analysis engine for the AI era. A formal dataflow analysis tool you can customize and self-host, built so AI agents drive your application security analysis without burning tokens on every scan. AI-ready open source alternative to Semgrep Pro and CodeQL.
Skill Claude CodeCodex
Analyze an OpenTaint scan's dropped external methods and decide which of them are propagators and optionally sinks. Use when a dropped-external-methods.yaml needs classification for dropped method type.
Skill Claude CodeCodex
Triage OpenTaint findings statically. Use when scan findings need a TP/FP verdict.
Skill Claude CodeCodex
Run an end-to-end OpenTaint application-security analysis while owning the long project build and scans and delegating each other pipeline stage. Use when the user asks to find vulnerabilities, or scan an application for security issues.
Skill Claude CodeCodex
Write the per-vuln-class security join rules that merge the created source/sink lib rules with the built-ins. Use to wire lib rules into project-level joins.
Skill Claude CodeCodex
Build a target project into an opentaint project model. Use whenever a fresh opentaint project model needed.
Skill Claude CodeCodex
Model a method's taint propagation as code-based dataflow approximation and refine it against a test project until the sample passes. Use for a dropped method that requires code-based approximation.
Skill Claude CodeCodex
Model a method's taint propagation as a passThrough approximation. Use for a dropped method whose propagation is simple copying.
Skill Claude CodeCodex
Author and verify an OpenTaint rule. Use whenever a rule creation is needed.
Skill Claude CodeCodex
Create an OpenTaint test project with positive/negative samples for verifying a rule or approximation. Use when a rule or approximation needs a test project to check against.
Skill Claude CodeCodex
Debug a rule or approximation that behaves unexpectedly by tracing where taint is dropped. Use when its samples won't pass after repeated attempts, or it passes tests but is wrong on a real scan.
Skill Claude CodeCodex
Classify project-used dependency members and record the taint sources among them not covered by the built-in rules. Use for the source-discovery depth pass.
Skill Claude CodeCodex
Reproduce a true-positive finding against the running application. Use when a finding needs dynamic confirmation.
Skill Claude CodeCodex
Run one stage of the OpenTaint pipeline by coordinating leaf subagents and deterministic joins. Use when a separate OpenTaint pipeline stage needs to be executed.
Skill Claude CodeCodex
Write a self-contained OpenTaint engine-issue report from an analysis diagnosis or a full-scan failure. Use when an engine-side issue needs a report.
Skill Claude CodeCodex
Run an OpenTaint scan on project and produces the SARIF report. Use whenever the user asks to scan or re-scan a project.
Skill Claude CodeCodex
Mark which of a project's dependency libraries could introduce taint sources. Use to start source discovery.
