Claude Code Subagent Patterns: 10 Reusable Agent Definitions
A Claude Code subagent is a delegated worker with its own context window, defined as a markdown file with YAML frontmatter in .claude/agents/. Subagents can edit files when you grant Edit or Write, nest three layers deep by default, and run 20 at a time. These 10 definitions cover the highest-value delegations.
Master Claude Code's 1M Context Window: Rewind, Compact, Clear, and Subagents
Claude Code's 1M token context window opens longer autonomous sessions but introduces 'context rot' -- degraded performance as the window fills. Master four turn-end tools: /rewind to drop bad branches, /compact to summarize and continue, /clear to start fresh with a distilled brief, and subagents to wall off noisy work in their own context.
Auto-Generate Cursor Rules and Skills From Your Chat History
Cursor stores agent sessions as JSONL transcripts on disk, which means an agent can read its own history and propose rules and skills based on patterns it spots. Eric Zakariasson's prompt formalizes this -- point Cursor at your transcripts and it emits ready-to-save .cursor/rules/*.mdc and .cursor/skills/<slug>/SKILL.md files for review.
Prompt Engineering in 2026: The Playbook That Works Across Claude and GPT

Start here, then apply the guide for your model.
