The AI-Powered Assumptions Ledger skill assists developers in generating a structured documentation of assumptions associated with code changes. By identifying underlying conditions that need to hold for code to function properly in production, this tool emphasizes code safety and reliability.
What this skill does
Generates an evidence-backed assumptions ledger for specific code segments such as Git diffs, features, endpoints, workers, migrations, or paths.
Identifies hidden assumptions and relevant failure modes to assist thorough code reviews
Provides repository evidence by pinpointing specific file paths and line ranges when possible.
Documents existing safeguards, falsification tests, and suggests recommended controls.
Assesses the status, evidence confidence, and priority for each assumption.
Who it is for
This skill is designed for developers and software teams utilizing AI coding agents like Claude Code, Cursor, or Codex. It supports those responsible for code reviews, release management, and deployment safety.
Use cases
Reviewing and validating the safety of changes in a Git repository.
Preparing for software releases while identifying potential edge cases.
Designing tests that focus on conditions that could lead to failure.
Evaluating concurrency concerns or analyzing retry mechanisms in code.
Technical details
Interactive integration with Claude Code, Cursor, and Codex, enhancing automated assumptions gathering.
Utilizes core capabilities like appsec and aiapplication to effectively compile relevant safety data from the codebase.
For authorised security testing, defensive research and educational use only.
