AI SDLC Harness

 AI Software Development Life Cycle (SDLC) Harness gives developers a structured way to direct and review work performed with AI coding agents. Here, “harness” means the workflow structure around the agent’s work: defining the task, guiding its progress, and recording what was checked. It keeps scope, acceptance criteria, and evidence alongside the code in the project repository, with developers retaining authority over key decisions and final acceptance.

Keep the task understandable as the work evolves

AI-assisted development needs a clear record of what was requested, what changed, and what was checked. Harness brings that record into the repository so it can be reviewed alongside the implementation.

How it fits into development

Define the work

Follow the workflow

Follow the workflow

Record the task's scope, acceptance criteria, and planned verification before implementation.

Follow the workflow

Follow the workflow

Follow the workflow

Use the current task context and workflow status to guide the developer or coding agent's next action.

Review the evidence

Follow the workflow

Review the evidence

Record actual checks and results, then review the change with the developer retaining authority over acceptance.

For developers and engineering teams

Harness is designed for teams bringing AI coding agents into their development workflow. It structures the work and its review record; it does not execute the coding agent or replace testing, security controls, or engineering judgment.

OWASP tools for AI transparency and security

Helen Oakley  created OWASP AIBOM Generator and OWASP FinBot CTF, turning practical challenges in AI transparency and agentic security into open-source tools. Both continue to evolve under her leadership with contributions from the OWASP community, under the OWASP GenAI Security Project. She also contributes to the OWASP Agent Control Standard (ACS), focusing on AgentBOM.

OWASP AIBOM Generator

Make AI model information easier to inspect.


OWASP AIBOM Generator creates AI Bills of Materials from model information on Hugging Face. It organizes available metadata into a CycloneDX document and highlights gaps through completeness scoring.


For security, engineering, and AI teams, this provides a practical starting point for examining model provenance, documentation, and supply chain transparency.

  • Gather metadata from model cards, configurations, and repository files.
  • Review a readable AIBOM and download its JSON representation.
  • Identify missing information for further investigation.

OWASP FinBot CTF

Explore agentic AI security through hands-on learning. 


OWASP FinBot CTF is an intentionally vulnerable application for learning how agentic AI systems can fail. Its vendor-management scenario gives participants a realistic setting for exploring interactions between AI agents, tools, business rules, and sensitive information.


Capture-the-flag challenges turn those interactions into practical learning for security practitioners, developers, and educators.

  • Explore prompt injection, tool misuse, and policy bypass in a purpose-built learning environment.
  • Investigate how agent behavior affects business processes and data.
  • Work through challenges connected to OWASP security guidance.

AgentBOM · OWASP ACS

 Making agent composition and dependencies visible.


The OWASP Agent Control Standard (ACS) is an evolving open standard for inspecting, tracing, and controlling AI agents. Helen leads its AgentBOM (AgBOM) work, focused on describing the components and dependencies that shape an agent’s operation.


An Agent Bill of Materials provides a structured view of the tools, models, and dependencies an agent uses—including changes as it operates.

  • Make agent components and dependencies visible.
  • Track how agent composition changes at runtime.
  • Provide context for security analysis and control decisions.
