description: CLAUDE.md is the markdown-based project memory format used by Anthropic's Claude Code CLI to give the model persistent,
  session-spanning instructions about a codebase. CLAUDE.md files are plain markdown that Claude Code loads at the start of
  every session by walking up the directory tree from the working directory, picking up files at organization-managed, user
  (~/.claude/CLAUDE.md), project (./CLAUDE.md or ./.claude/CLAUDE.md), and local (./CLAUDE.local.md) scopes. The format supports
  an @path import syntax for composing files together (up to five hops, relative or absolute), HTML block comments that are
  stripped before injection, an AGENTS.md import pattern for compatibility with other agents, and a complementary .claude/rules/
  directory of path-scoped markdown rules with YAML frontmatter. CLAUDE.md is the human-authored counterpart to Claude Code's
  auto memory at ~/.claude/projects/<project>/memory/MEMORY.md, which Claude writes itself.

    user message at session start. Recommended size is under 200 lines per file with concrete, verifiable instructions and

  description: The @path/to/file syntax expands and inlines another file into a CLAUDE.md at load time. Imports support relative
    and absolute paths, recursive imports up to five hops, and are commonly used to pull in README, AGENTS.md, package.json,
    or shared instruction files from a user's home directory.

    user (~/.claude/CLAUDE.md), project (./CLAUDE.md or ./.claude/CLAUDE.md checked into source control), and local (./CLAUDE.local.md,
    gitignored). All discovered files are concatenated into context rather than overriding each other.'

  description: The .claude/rules/ directory holds modular markdown rule files with optional YAML frontmatter declaring a paths
    list of glob patterns. Rules without paths load at launch alongside CLAUDE.md; path-scoped rules load only when Claude
    reads matching files.

  description: Auto memory is the machine-managed companion to CLAUDE.md. Claude Code maintains ~/.claude/projects/<project>/memory/MEMORY.md
    as a concise index plus topic files written and read by the agent across sessions. The first 200 lines or 25 KB of MEMORY.md
    load at session start.
