Audit playbook module for business logic flaws and race conditions covering workflow and state-machine bypass, price and amount tampering, check-then-act TOCTOU races, time-based logic abuse, limit counting defects, approval-flow weaknesses, and referral or gift-system abuse across all mainstream languages and frameworks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Scope & Objectives ### Objective Audit the target repository for flaws where the application trusts the client's data, ordering, or timing instead of enforcing its own rules: checkout steps that can be skipped, totals that arrive precomputed, balances debited through unsynchronized read-modify-write sequences, trials extended by client clocks, limits counted on the wrong field, approvals signed by their own requester. For every finding produce file:line evidence, a static-first reproduction recipe, a severity with rationale, and a stack-correct fix built around transactions, row locks, atomic conditional updates, idempotency keys, or server-side transition guards. ### In Scope | Class | Typical finding | Primary CWE | |---|---|---| | Workflow / state-machine bypass | Direct call to the order-creation endpoint skipping payment; UI-only email-verification gate; password change without old password; step tokens accepted unsigned or unvalidated | CWE-20 (where a client-set field drives the transition) | …

How to install
mdr add as-foss/aegis-skills/aegis-business-logic-races@sha256:ddb41cc0f45bc0cfThe line at the top of this page pins the label git:20260826.9702747, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
