SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents AI coding agents from underperforming due to missing, stale, or overgrown context by systematically curating what the agent sees and how it’s structured.

Core Features & Use Cases

  • Context hierarchy control: Loads the most persistent rules files first, then relevant memory, architecture/spec sections, task-relevant source, and finally live state and conversation.
  • Drift and quality guardrails: Recommends reloading rules + memory and re-scoping when output quality drifts or when switching between unrelated parts of the codebase.
  • High-stakes subagent fan-out: Enforces bounded wave sizes, strict per-agent output budgets, scope bounding, and a required status protocol to avoid context flooding.
  • Confusion management pattern: Forces explicit surfacing of conflicting or missing requirements instead of silently choosing a direction.
  • Inline planning discipline: Encourages emitting a lightweight plan before executing multi-step changes to reduce rework.

Quick Start

Instruct your agent to apply context engineering by loading the correct rules files and reviewing relevant memory before working on a specific task, then scope any subagent fan-out to a small wave with bounded prompts and outputs.

FAQPage Schema
What is context engineering for AI coding agents?

Context engineering is the systematic curation of what an AI coding agent sees by structuring rules, memory, specs, source, and live state into a task-appropriate hierarchy to prevent missing or overgrown context.

How do I stop my AI agent's output quality from drifting during long sessions?

To stop output quality drift, reload your agent's rules and memory files, re-scope the task, and force explicit confusion management to surface conflicting requirements before continuing the session.

How do I manage subagent fan-out without flooding the context window?

Manage subagent fan-out by enforcing bounded wave sizes, assigning strict per-agent output budgets, bounding prompt scopes, and requiring a status protocol to prevent context flooding.

Why does my AI coding agent silently choose the wrong implementation path?

Agents choose the wrong path when missing or conflicting requirements are not surfaced; applying a confusion management pattern forces the agent to explicitly state confusion instead of guessing.

What is the best way to structure rules files for AI coding agents?

The best way to structure rules files is through a context hierarchy: load the most persistent rules first, then relevant memory, architecture sections, task source, and finally live state.

Do I need to plan before my AI agent executes multi-step codebase changes?

Yes, you need an inline planning discipline that emits a lightweight plan before executing multi-step changes, which reduces rework and ensures prompts are bounded and verifier-friendly.
