Claude Code guides
Every guide here comes out of running Claude Code as a dispatcher: sessions started headlessly, tickets routed to a model tier, context measured because the bill is made of it. Numbers carry their source.
- Claude Code Hooks: A Complete Reference What claude code hooks are, where they live in settings.json, every documented hook event, and the PreToolUse pattern that cuts context before it's spent.
- Claude Code Subagents What a Claude Code subagent is, its config file, when delegation pays off, how to size the model, and the failure modes nobody documents.
- How Much Does Claude Code Cost? Claude Code's plan prices, what each tier includes, API-billed cost per developer, and how to measure your own cost per unit of work.
- Claude Code Worktree Setup for Parallel Agents How git worktrees let Claude Code agents run in parallel, the shared-checkout failure that corrupts uncommitted work, and the RAM leak nobody mentions.
- Changing the Claude Code Model, and Which One to Pick The /model command, the --model flag, and the settings that set a default, plus which model to pick for which job and when to change it.
- Claude Code Plugin Marketplace How to add a plugin marketplace, install and manage plugins, check what a plugin costs your context, and publish your own with a real manifest.
- Claude Code Statusline The full stdin payload, a paste-and-run script, and recipes for context percentage, cost, cache warmth, and chaining an existing statusline.
- How to Make Claude Code Stop Asking for Permission The fastest fix is a settings allowlist. Then the full permission mode table, the bypass option, and what breaks it in headless runs.
- Claude Code Headless Mode How claude -p actually works in production: invocation, output parsing, and the silent failure mode that costs the most to debug.
- Claude Code Token Usage Claude Code resends the full conversation on every request. Here's the mechanism, how to see your usage, and what actually cuts it.
- Claude Code Usage Limit What each Claude Code usage limit message means, when it resets, and whether switching models actually helps you keep working.
