Skills Best Practice
Claude Code skills — frontmatter fields and official bundled skills.
| ← Back to Claude Code Best Practice |  |
Frontmatter Fields (16)
| Field | Type | Required | Description |
|---|---|---|---|
name |
string | No | Display name and /slash-command identifier. Defaults to the directory name if omitted |
description |
string | Recommended | What the skill does. Shown in autocomplete and used by Claude for auto-discovery |
when_to_use |
string | No | Additional context for when Claude should invoke the skill — trigger phrases and example requests. Appended to description in the skill listing, counts toward the 1,536-character cap |
argument-hint |
string | No | Hint shown during autocomplete (e.g., [issue-number], [filename]) |
arguments |
string/list | No | Named positional arguments for $name substitution in the skill content. Accepts a space-separated string or a YAML list — names map to argument positions in order |
disable-model-invocation |
boolean | No | Set true to prevent Claude from automatically invoking this skill |
user-invocable |
boolean | No | Set false to hide from the / menu — skill becomes background knowledge only, intended for agent preloading |
allowed-tools |
string | No | Tools allowed without permission prompts when this skill is active |
disallowed-tools |
string/list | No | Tools removed from Claude's available pool while the skill is active (e.g. block AskUserQuestion for a background loop). Accepts a space/comma-separated string or YAML list — the restriction clears on the next message |
model |
string | No | Model to use when this skill runs (e.g., haiku, sonnet, opus) |
effort |
string | No | Override the model effort level when invoked (low, medium, high, xhigh, max) |
context |
string | No | Set to fork to run the skill in an isolated subagent context |
agent |
string | No | Subagent type when context: fork is set (default: general-purpose) |
hooks |
object | No | Lifecycle hooks scoped to this skill |
paths |
string/list | No | Glob patterns that limit when the skill auto-activates. Accepts a comma-separated string or YAML list — Claude loads the skill only when working with matching files |
shell |
string | No | Shell for !`command` blocks — bash (default) or powershell. Requires CLAUDE_CODE_USE_POWERSHELL_TOOL=1 |
(13)
| # | Skill | Description |
|---|---|---|
| 1 | code-review |
Review the current diff for correctness bugs at a chosen effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage) — --comment posts findings as inline PR comments |
| 2 | batch |
Run commands across multiple files in bulk |
| 3 | debug |
Debug failing commands or code issues |
| 4 | loop |
Run a prompt or slash command on a recurring interval (up to 3 days) |
| 5 | claude-api |
Build apps with the Claude API or Anthropic SDK — triggers on anthropic / @anthropic-ai/sdk imports |
| 6 | fewer-permission-prompts |
Scan transcripts for common read-only Bash/MCP calls and add a prioritized allowlist to .claude/settings.json to reduce permission prompts |
| 7 | run |
Launch and drive the project's app to see a change working in the real app (not just tests). Requires v2.1.145 |
| 8 | verify |
Build and run the app to confirm a code change does what it should, without falling back to tests or type checks. Requires v2.1.145 |
| 9 | run-skill-generator |
Teaches /run and /verify how to build and launch the project — records a per-project launch recipe at .claude/skills/run-<name>/. Requires v2.1.145 |
| 10 | simplify |
Review changed code for cleanup opportunities (reuse, simplification, efficiency, abstraction level), four review agents in parallel. From v2.1.154 it does not hunt for correctness bugs — use /code-review for that |
| 11 | design-sync |
Convert your repo's React design system and upload it to Claude Design — optionally name the design system (e.g., /design-sync Acme DS). First-time sync verifies every component and can take hours on large repos. Available on the Anthropic API only (unavailable on Bedrock, Google Cloud Agent Platform, and Microsoft Foundry) |
| 12 | dataviz |
Design charts, graphs, and dashboards with a color-palette validator for accessible, consistent visualizations — triggers on requests for any chart, graph, plot, or data visualization in any output medium. Introduced v2.1.198 |
| 13 | doctor |
Setup/health checkup for your Claude Code configuration. The one bundled skill exempt from disableBundledSkills — stays typable even when that setting is on. Reclassified from a built-in command to a bundled skill in v2.1.205 |
