The Permission Rules You Added for Safety Are Taxing Every Turn — Auditing the Ruleset Without Loosening It
Version 2.1.209 fixed the per-turn slowdown from large deny/ask rulesets, but the design debt in your rules is still yours. Here are the audit scripts, a shadowing detector, a turn-timing harness, and how to fold enumerated rules into prefix rules safely.
When You Fan Out Streaming Sessions, Your Laptop's CPU Gives Out First — An Adaptive Throttle That Caps Concurrency by Measured Load
Even with lighter streaming, fanning out many sessions on one machine saturates the host CPU before anything else. Here is why a fixed semaphore fails, plus a working adaptive gate that raises and lowers concurrency from measured CPU.
I Edited One Line of a Tool Description and the Whole Prompt Cache Rebuilt — Where to Place cache_control Breakpoints
Hit rate suddenly flatlined at zero because a volatile block sat upstream of stable ones. This walks through how prefix-cache cascade invalidation works, how to reorder blocks from stable to volatile, and where to spend your four cache_control breakpoints — with code and decision tables.
5 Practical Ways to Work Around Claude Code's Context Window Limit
When Claude Code warns you that the context limit is approaching on large codebases or long sessions, here are five practical approaches — from /clear and /compact to CLAUDE.md and scope splitting.
Four Infrastructure Levers That Cut Claude API Latency Before You Touch the Model
Before you downgrade Sonnet to Haiku to chase faster responses, the network and request shape around your Claude API calls usually has more headroom. Here are four infrastructure levers — region selection, connection pooling, prompt caching, and streaming — with code and measurement notes.
Claude Code Context Window Mastery — 7 Production Patterns to Stop Sessions From Stalling
Most slowdowns and silent quality drops in Claude Code on large repos come from context window management, not from model limits. This guide walks through seven patterns I rely on in production, with measurement scripts and runtime rules.
