SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Validate that coding can start safely, deterministically, and within policy by enforcing prerequisites and governance constraints.

Core Features & Use Cases

  • Environment and branch safety checks to prevent risky work on protected branches.
  • STATE file presence and contract validation to ensure scope and intent are explicit.
  • Immutable template checks and gated routing to the exact next skill when prerequisites are satisfied.
  • Blockers surfaced with clear next steps to keep planning and coding in sync.

Quick Start

Run the preflight check to confirm execution prerequisites are met before starting coding tasks.

Frequently Asked Questions about preflight

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I verify execution readiness before coding on a protected branch?

Validate coding readiness by running a preflight check that enforces branch safety, STATE file presence, and immutable templates. It surfaces blockers and guides the exact next skill before proceeding.

What is governance-driven development and how does it gate coding tasks?

Governance-driven development applies preflight gatekeeping to enforce explicit gates from constitution and AGENTS/STATE artifacts. This prevents unsafe coding starts by validating prerequisites deterministically within policy.

How do I prevent unsafe coding starts when my project state contract is missing?

Prevent unsafe coding starts by running a preflight check that validates STATE file presence and state contracts. It surfaces missing scope or intent as blockers with clear next steps to resolve before coding.

Does preflight gatekeeping work with immutable templates in my repository?

Preflight gatekeeping validates immutable template integrity before coding begins. It ensures execution prerequisites are met deterministically and routes to the exact next skill when templates are verified.

Why does my coding task get blocked by preflight checks on protected branches?

Coding tasks get blocked because branch safety validation prevents risky work on protected branches. The preflight check enforces governance constraints and surfaces blockers with exact next steps to resolve.
