I used to paste the same review checklist and task steps into Claude Code whenever I needed them. I moved those recurring instructions into skills: small directories with a SKILL.md file that Claude Code can load by name or when a task matches the skill’s description. For my workflow, that means less repeated setup and a more organized way to reuse procedures—not a guarantee that every answer will improve.
What changed when I stopped repasting prompts
A one-off request still belongs in a chat. But when I found myself pasting the same instructions repeatedly—a review checklist, for example, or a sequence of steps for a recurring task—I turned them into a skill instead.

That change made the workflow feel better because the instructions now have a home and can be reused. The format also separates long procedures from information Claude Code may need in every session: a skill’s body loads when the skill is used, rather than being included as standing project guidance. Anthropic describes this distinction in its Claude Code skills documentation. It explains the organization and loading behavior; it does not establish that skills universally make Claude Code more productive or produce better answers.

A skill is a directory containing a SKILL.md file. That file has YAML frontmatter, including a name and description, followed by Markdown instructions. The name can be invoked as a slash command; the description helps Claude decide whether the skill is relevant to a task and should be loaded automatically.
#1 Best Overall
Skills are suited to repeatable instructions, checklists, and multi-step procedures. They can also include supporting files, which is useful when a workflow needs more than one set of instructions. Existing Markdown files in .claude/commands/ continue to work, so there is no need to migrate every command just to use skills.
How to turn a repeated prompt into a skill
- Choose a prompt you actually reuse. Start with a recurring checklist or task procedure, rather than a one-time request or a stable fact that should remain available as general project guidance.
- Choose where it belongs. For personal use across projects, use
~/.claude/skills/. For a workflow shared with a repository, use.claude/skills/and commit the skill so teammates can use it. Anthropic documents these and other supported locations in its skills guide. - Create a skill directory and its instruction file. For example, a personal skill named
review-checklistcan live at~/.claude/skills/review-checklist/SKILL.md. Put the reusable steps in the Markdown body and include the required YAML frontmatter with a clear name and description. - Make the description specific. Say what the skill does and the kind of task that should trigger it. A description such as “Review a pull request for correctness, edge cases, and maintainability” gives Claude a more useful signal than a broad label like “coding help.”
- Test both ways of loading it. Invoke it directly as
/review-checklist, then try a naturally phrased review request that should match its description. Check whether the expected instructions are applied and whether unrelated tasks trigger the skill.
For a team workflow, use the project location instead—for example, .claude/skills/review-checklist/SKILL.md—and commit it with the repository. The official documentation provides the current file-format details and examples; check it when implementing a skill because invocation rules and locations can change.
Use CLAUDE.md for project facts and skills for procedures
I use CLAUDE.md for stable information Claude Code should have as project guidance, such as conventions or facts about the codebase. I put a task procedure in a skill when it is something to run for a particular kind of work. Anthropic’s skills documentation specifically suggests moving a section out of CLAUDE.md when it has grown into a procedure rather than a stable fact.
The practical distinction is about when the instructions matter. Project guidance can apply broadly; a skill’s body is loaded when that skill is used. Anthropic puts it this way: “Unlike CLAUDE.md content, a skill’s body loads only when it’s used, so long reference material costs almost nothing until you need it.”
Choose a location and invocation method that fit
| Decision | Choose this when |
|---|---|
Personal skill in ~/.claude/skills/ |
You want the workflow available across projects on your machine. |
Project skill in .claude/skills/ |
The workflow belongs to a repository and should be available to teammates when committed. |
| Direct slash command | You want to decide explicitly when to run the procedure. |
| Automatic loading | You want Claude to select the skill when a task matches its description. |
Existing .claude/commands/ file |
Your current custom command already does the job and does not need skill features such as supporting files or automatic loading. |
Claude Code also supports other skill arrangements, including nested, enterprise, additional-directory, plugin, and claude.ai-synced skills. Their availability and behavior depend on setup, so consult the official skills documentation for the current details.
Make the instructions easier to follow
A skill is reusable, but it is not a promise of identical results every time. Write instructions that are clear about the task, relevant context, and expected output. Include examples when they clarify what a good result looks like. Anthropic’s prompting best practices recommend clarity and useful examples, and caution that aggressively worded instructions intended to force tool or skill use can overtrigger with some model versions.
Rank #4
If a skill activates too often, narrow its description: name the task and conditions where it applies, and remove broad language that could match unrelated requests. If Claude does not select it automatically, try the slash command to distinguish a discovery issue from a problem with the skill’s instructions.
When a skill seems to be missing
First confirm that the directory and SKILL.md are in the location you intended to use, and that the skill name and description are present in the YAML frontmatter. Then check how Claude Code was started: the CLI reference says --safe-mode disables customizations, including skills, while --bare skips automatic discovery. A skill may therefore be unavailable because of the session mode, not because its file is malformed. See Anthropic’s CLI reference for current flag behavior.
Because Claude Code can change, check the live skills guide and CLI reference if a location, invocation method, or flag does not behave as expected.
Decide what to migrate—and what to leave alone
Move a prompt into a skill when you repeatedly use its instructions and would benefit from a reusable procedure, optional automatic selection, or supporting files. Keep a simple existing command if it already works, and keep stable project facts in CLAUDE.md. For a personal workflow, use personal scope; for a procedure teammates need, use project scope.
My improvement is personal: repeated prompts became easier to manage once they were in named, reusable files. To judge whether the change helps your own work, compare similar tasks with similar inputs, save the outputs, and note where Claude follows the procedure, misses a step, or needs extra direction. The format provides a practical way to organize and load instructions; the result still depends on the task and the instructions themselves.
