CLAUDE.md Improver

CLAUDE.md Improver is an official skill from Anthropic's claude-plugins-official repository. According to the provider, it helps Claude Code systematically inspect and improve CLAUDE.md files across a repository. These files hold durable project context: commands, architecture, conventions, key files, testing workflows, and non-obvious pitfalls that should guide future sessions. The skill is not a standalone editor, hosting service, or substitute for team ownership. It provides a structured workflow in which Claude discovers existing context files, evaluates their quality, presents a report, and proposes targeted improvements.

Repository discovery

The workflow starts by finding CLAUDE.md files and related local variants throughout the repository. Project-root files, nested directories, package folders, and local overrides are considered. This is useful in monorepos, where different areas may need different instructions and Claude Code can automatically discover guidance in parent directories. A complete inventory reduces the chance of overlooking a local rule or treating a broad file as the only source of truth. Before editing, a person should confirm whether each file is shared through version control or intended only for one workstation.

Quality assessment and reporting

The skill then evaluates each discovered file against practical criteria. These include documented build, test, and development workflows, architectural clarity, project-specific patterns, concision, currency, and actionability. According to the provider, the result can be a quality report with a score and concrete gaps. A useful report distinguishes missing information from unnecessary prose. It might identify an obsolete test command, a missing entry point, or an architectural assumption that no longer matches the repository. A score is an orientation signal, not an objective proof of security or engineering quality.

Targeted improvements

The documented workflow requires a report to be presented before updates are made and calls for user approval before editing. This separation matters because a plausible recommendation is not automatically an authorized change. After approval, the file should receive only useful, reusable additions: a command that really works, a non-obvious project mechanism, or a dependable testing workflow. Obvious information, generic advice, and one-off fixes should stay out. Claude Code uses its reading, search, shell, and editing capabilities for this work. Every approved change should still be reviewed as a diff, exercised locally, and accepted by a responsible maintainer.

Boundaries and security

CLAUDE.md is instruction text and therefore a sensitive trust boundary. Unreviewed content can steer Claude toward incorrect, risky, or unnecessary actions. The skill does not guarantee currency, security, privacy, licensing compliance, or domain correctness. Pay particular attention to destructive commands, network access, secret handling, deployment, and changes to external state. Credentials, tokens, private keys, personal production data, and internal values should never be placed in a shared context file. According to the provider, quality should be reported and approval obtained before writing; that human control remains necessary even for a small addition. Actual outcomes depend on the repository, Claude Code configuration, available tools, and selected model. The skill improves project context but does not replace code review or tests.

Source and catalog context

The authoritative source is plugins/claude-md-management/skills/claude-md-improver in Anthropic's official repository. The repository contains the skill text and is identified by the provider as Apache-2.0 licensed. Anthropic's official Claude Code memory documentation provides complementary context for how CLAUDE.md functions as project and working memory. This entry states no concrete prices or quotas because conditions depend on the Claude Code setup and the provider terms in force at the time of use. CLAUDE.md Improver suits teams that want to review project instructions regularly for clarity, currency, and actionability. It remains an instructional skill inside Claude Code, not an autonomous governance process.
