Teaching Your Agent Standard Operating Procedures
Skills are Standard Operating Procedures the agent loads only when needed — progressive disclosure applied to AI context. Without a forced-eval hook they activate 55% of the time; with one, 100%. That gap is the difference between skills working and skills being decoration. Plus why hooks are the enforcement layer that makes any of it reliable.

The Great Agent Tooling Debate
Load 84 MCP tools and 15,540 tokens are gone before you ask a question; after thirty minutes you've burned 40% of your context on tool definitions you didn't use. Holmes and Yilmaz make the case for CLI-first, and I've mostly come round: CLIs are debuggable, composable, and 92-98% cheaper in tokens. MCP still earns its keep for a few tools, but the default should flip.

Surviving the Context Window in Practice
The context window is a budget, not a feature. Auto-compaction hides the bill until the agent starts hallucinating. Practical tactics for staying under budget: scope per session, offload to disk, dispatch subagents for research, and clear aggressively between phases. The goal isn't a bigger window; it's needing less of it.

The Only Workflow That Works
AI agents amplify whatever engineering process they're given. Bad specs produce confident garbage at machine speed. Three practitioner workflows for separating planning from execution: the normal coding flow, Boris Tane's annotated plan cycle, and Jamon Holmgren's Night Shift spec discipline. The pattern is simple; the discipline is resisting the urge to skip straight to implementation.
