The current Claude Code memory documentation does not describe a # shortcut for adding text to CLAUDE.md. That means the reviewed docs do not substantiate the shortcut; it does not prove the feature is absent or no longer works. Runtime behavior remains unverified.
What the current documentation says about #
Anthropic’s Claude Code memory documentation explains how instruction files work, but does not document a # quick-add action. On the basis of that page alone, you cannot confirm that typing # adds a note to CLAUDE.md. Nor does the omission establish that the shortcut has been removed or is unavailable in a particular release.

The docs explain that CLAUDE.md files provide persistent instructions. To verify a shortcut for a specific Claude Code version, you would need a current version-specific reference or a direct check in that version; the documentation reviewed here does not settle live behavior.

Anthropic describes CLAUDE.md files as Markdown files that give Claude persistent instructions for a project, a personal workflow, or an organization. They are context Claude tries to follow, not enforced configuration. For rules that must be enforced regardless of the model’s choice, the docs point to a PreToolUse hook instead.
#1 Best Overall
Where instruction files can live
The documentation describes several scopes: managed policy; user instructions at ~/.claude/CLAUDE.md; project instructions at ./CLAUDE.md or ./.claude/CLAUDE.md; and local project instructions at ./CLAUDE.local.md. Parent-directory instruction files load at launch, while files in subdirectories load on demand. These are documented ways to supply instructions; the page does not identify # as a way to write them.
Importing other instruction files
A CLAUDE.md file can include another file with an import such as @path/to/import. Imports load at launch, can use relative or absolute paths, and relative paths resolve from the file containing the import. Imported content still contributes to context; splitting instructions across files does not reduce that cost.
Rank #2
CLAUDE.md instructions versus auto memory
Claude Code has two complementary memory systems, according to Anthropic’s documentation. The distinction matters if the goal is to preserve a note across sessions: instructions are written by the user, while auto memory consists of notes Claude writes about learnings and patterns.

| System | Who writes it | Purpose | Scope |
|---|---|---|---|
CLAUDE.md instructions |
You or your organization | Persistent guidance for Claude to try to follow | May apply to a personal workflow, project, or organization, depending on file location |
| Auto memory | Claude | Notes about learnings and patterns | Separate from user-authored instruction files; the documentation describes it as another way to carry information across sessions |
Neither system is a hard enforcement layer. The memory documentation explains their roles and loading behavior, but does not establish that the # key writes to either one.
Practical takeaway
If you need a persistent instruction, the documented approach is to put it in the appropriate CLAUDE.md file for its scope. If you need a rule that cannot be left to Claude’s judgment, use a hook such as PreToolUse. Treat the # quick-add behavior as unconfirmed by the current memory documentation, rather than as a verified feature or a definitively removed one.
