SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents project failures caused by silently expired assumptions, ensuring that delivery decisions remain grounded in current reality rather than outdated premises.

Core Features & Use Cases

  • Expiry Detection: Identifies when dependencies, business rules, or operating conditions have shifted enough to invalidate previous assumptions.
  • Evidence-Linked Review: Generates structured reports linking change signals to specific assumptions, providing a clear audit trail for risk management.
  • Use Case: Before a major system migration, use this Skill to audit architectural assumptions against recent traffic patterns and dependency updates to avoid unexpected downtime.

Quick Start

Use the assumption-expiry-radar skill to audit the current project assumptions against the provided change logs and system documentation.

FAQPage Schema
How do I track stale project assumptions before a major release?

Validate expired assumptions by inputting bounded assumptions, source evidence, and change signals to detect shifts in dependencies or business rules. This generates an evidence-linked expiry review applicable to pre-implementation, release, and incident follow-up workflows where delivery depends on stable environmental premises.

What causes silently expired assumptions in project delivery?

Expired assumptions occur when code, dependencies, business rules, or operating conditions change without updating foundational project premises. Identifying these shifts requires comparing explicit bounded assumptions against current change signals to prevent delivery failures and unexpected downtime.

Can I audit architectural assumptions against recent dependency updates?

Yes, you can audit architectural assumptions against recent dependency updates by providing explicit bounded assumptions and source evidence. The review links change signals to specific assumptions, producing a clear audit trail for risk management and delivery assurance before system migrations.

What inputs do I need to validate assumption expiry?

Validating assumption expiry requires explicit input of bounded assumptions, source evidence, and change signals. Providing these inputs allows the system to identify when dependencies or operating conditions have shifted enough to invalidate previous assumptions and generate a structured review.

When should I run an assumption expiry review for risk management?

Run an assumption expiry review during pre-implementation, release, and incident follow-up workflows where delivery depends on stable environmental or business premises. It is critical before major system migrations to audit architectural assumptions against recent traffic patterns and dependency updates.
