description: Analyze this code for performance issues and suggest optimizations

Analyze the performance of this code and suggest three specific optimizations:

Usage: /optimize

Claude receives the expanded prompt and analyzes the code in context.

All generated slash commands should use XML tags in the body (after YAML frontmatter) for clarity and consistency.

- What the command does and why it matters

What needs to happen and why this matters. Context about who uses this and what it accomplishes.

or - How to execute the command

Sequential steps to accomplish the objective: 1. First step 2. Second step 3. Final step

- How to know the command succeeded

Clear, measurable criteria for successful completion.

- When loading dynamic state or files

Current state: ! git status Relevant files: @ package.json

(Note: Remove the space after @ in actual usage)

- When producing artifacts that need checking

Before completing, verify: - Specific test or check to perform - How to confirm it works

- When running tests is part of the workflow

Run tests: ! npm test Check linting: ! npm run lint

- When creating/modifying specific files Files created/modified: - `./path/to/file.ext` - Description --- name: example-command description: Does something useful argument-hint: [input] --- Process $ARGUMENTS to accomplish [goal]. This helps [who] achieve [outcome]. Current state: ! `relevant command` Files: @ relevant/files 1. Parse $ARGUMENTS 2. Execute operation 3. Verify results - Operation completed without errors - Output matches expected format Simple commands (single operation, no artifacts): Required: , , Example: /check-todos, /first-principles Complex commands (multi-step, produces artifacts): Required: , , Add: (if loading state), (if creating files), (what gets created) Example: /commit, /create-prompt, /run-prompt Commands with dynamic arguments: Use $ARGUMENTS in or tags Include argument-hint in frontmatter Make it clear what the arguments are for Commands that produce files: Always include tag specifying what gets created Always include tag with checks to perform Commands that run tests/builds: Include tag with specific commands Include pass/fail criteria in The skill should intelligently determine whether a slash command needs arguments. User provides specific input: /fix-issue [issue-number] - Needs issue number /review-pr [pr-number] - Needs PR number /optimize [file-path] - Needs file to optimize /commit [type] - Needs commit type (optional) Pattern: Task operates on user-specified data Include argument-hint: [description] in frontmatter and reference $ARGUMENTS in the body. Self-contained procedures: /check-todos - Operates on known file (TO-DOS.md) /first-principles - Operates on current conversation /whats-next - Analyzes current context Pattern: Task operates on implicit context (current conversation, known files, project state) Omit argument-hint and don't reference $ARGUMENTS. In tag: Fix issue #$ARGUMENTS following project conventions. This ensures bugs are resolved systematically with proper testing. In tag: 1. Understand issue #$ARGUMENTS from issue tracker 2. Locate relevant code 3. Implement fix 4. Add tests In tag: Issue details: @ issues/$ARGUMENTS.md Related files: ! `grep -r "TODO.*$ARGUMENTS" src/` (Note: Remove the space after the exclamation mark in actual usage) For structured input, use $1, $2, $3: --- argument-hint: --- Review PR #$1 with priority $2 and assign to $3. Usage: /review-pr 456 high alice Project commands: .claude/commands/ Shared with team via version control Shows (project) in /help list Personal commands: ~/.claude/commands/ Available across all your projects Shows (user) in /help list File naming: command-name.md → invoked as /command-name description: Analyze this code for performance issues and suggest optimizations Shown in the /help command list. allowed-tools: Bash(git add:*), Bash(git status:*), Bash(git commit:*) Formats: Array: allowed-tools: [Read, Edit, Write] Single tool: allowed-tools: SequentialThinking Bash restrictions: allowed-tools: Bash(git add:*) If omitted: All tools available Command file: .claude/commands/fix-issue.md --- description: Fix issue following coding standards --- Fix issue #$ARGUMENTS following our coding standards Usage: /fix-issue 123 high-priority Claude receives: "Fix issue #123 high-priority following our coding standards" Command file: .claude/commands/review-pr.md --- description: Review PR with priority and assignee --- Review PR #$1 with priority $2 and assign to $3 Usage: /review-pr 456 high alice Claude receives: "Review PR #456 with priority high and assign to alice" See references/arguments.md for advanced patterns. Execute bash commands before the prompt using the exclamation mark prefix directly before backticks (no space between). Note: Examples below show a space after the exclamation mark to prevent execution during skill loading. In actual slash commands, remove the space. Example: --- description: Create a git commit allowed-tools: Bash(git add:*), Bash(git status:*), Bash(git commit:*) --- ## Context - Current git status: ! `git status` - Current git diff: ! `git diff HEAD` - Current branch: ! `git branch --show-current` - Recent commits: ! `git log --oneline -10` ## Your task Based on the above changes, create a single git commit. The bash commands execute and their output is included in the expanded prompt. Use @ prefix to reference specific files: --- description: Review implementation --- Review the implementation in @ src/utils/helpers.js (Note: Remove the space after @ in actual usage) Claude can access the referenced file's contents. 1. Always use XML structure # All slash commands should have XML-structured bodies After frontmatter, use XML tags: - What and why (always) - How to do it (always) - Definition of done (always) Additional tags as needed (see xml_structure section) 2. Clear descriptions # Good description: Analyze this code for performance issues and suggest optimizations # Bad description: Optimize stuff 3. Use dynamic context for state-dependent tasks Current git status: ! `git status` Files changed: ! `git diff --name-only` 4. Restrict tools when appropriate # For git commands - prevent running arbitrary bash allowed-tools: Bash(git add:*), Bash(git status:*), Bash(git commit:*) # For analysis - thinking only allowed-tools: SequentialThinking 5. Use $ARGUMENTS for flexibility Find and fix issue #$ARGUMENTS 6. Reference relevant files Review @ package.json for dependencies Analyze @ src/database/* for schema (Note: Remove the space after @ in actual usage) Simple analysis command: --- description: Review this code for security vulnerabilities --- Review code for security vulnerabilities and suggest fixes. 1. Scan code for common vulnerabilities (XSS, SQL injection, etc.) 2. Identify specific issues with line numbers 3. Suggest remediation for each issue - All major vulnerability types checked - Specific issues identified with locations - Actionable fixes provided Git workflow with context: --- description: Create a git commit allowed-tools: Bash(git add:*), Bash(git status:*), Bash(git commit:*) --- Create a git commit for current changes following repository conventions. - Current status: ! `git status` - Changes: ! `git diff HEAD` - Recent commits: ! `git log --oneline -5` 1. Review staged and unstaged changes 2. Stage relevant files 3. Write commit message following recent commit style 4. Create commit - All relevant changes staged - Commit message follows repository conventions - Commit created successfully Parameterized command: --- description: Fix issue following coding standards argument-hint: [issue-number] --- Fix issue #$ARGUMENTS following project coding standards. This ensures bugs are resolved systematically with proper testing. 1. Understand the issue described in ticket #$ARGUMENTS 2. Locate the relevant code in codebase 3. Implement a solution that addresses root cause 4. Add appropriate tests 5. Verify fix resolves the issue - Issue fully understood and addressed - Solution follows coding standards - Tests added and passing - No regressions introduced File-specific command: --- description: Optimize code performance argument-hint: [file-path] --- Analyze performance of @ $ARGUMENTS and suggest specific optimizations. This helps improve application performance through targeted improvements. 1. Review code in @ $ARGUMENTS for performance issues 2. Identify bottlenecks and inefficiencies 3. Suggest three specific optimizations with rationale 4. Estimate performance impact of each - Performance issues clearly identified - Three concrete optimizations suggested - Implementation guidance provided - Performance impact estimated Usage: /optimize src/utils/helpers.js See references/patterns.md for more examples. Arguments reference: references/arguments.md $ARGUMENTS variable Positional arguments ($1, $2, $3) Parsing strategies Examples from official docs Patterns reference: references/patterns.md Git workflows Code analysis File operations Security reviews Examples from official docs Tool restrictions: references/tool-restrictions.md Bash command patterns Security best practices When to restrict tools Examples from official docs Analyze the user's request: What is the command's purpose? Does it need user input ($ARGUMENTS)? Does it produce files or artifacts? Does it require verification or testing? Is it simple (single-step) or complex (multi-step)? Create frontmatter: --- name: command-name description: Clear description of what it does argument-hint: [input] # Only if arguments needed allowed-tools: [...] # Only if tool restrictions needed --- Create XML-structured body: Always include: - What and why - How to do it (numbered steps) - Definition of done Include when relevant: - Dynamic state (! commands) or file references (@ files) - Checks to perform if creating artifacts - Test commands if tests are part of workflow - Files created/modified Integrate $ARGUMENTS properly: If user input needed: Add argument-hint and use $ARGUMENTS in tags If self-contained: Omit argument-hint and $ARGUMENTS Apply intelligence: Simple commands: Keep it concise (objective + process + success criteria) Complex commands: Add context, verification, testing as needed Don't over-engineer simple commands Don't under-specify complex commands Save the file: Project: .claude/commands/command-name.md Personal: ~/.claude/commands/command-name.md A well-structured slash command meets these criteria: YAML Frontmatter: description field is clear and concise argument-hint present if command accepts arguments allowed-tools specified if tool restrictions needed XML Structure: All three required tags present: , , Conditional tags used appropriately based on complexity No raw markdown headings in body All XML tags properly closed Arguments Handling: $ARGUMENTS used when command operates on user-specified data Positional arguments ($1, $2, etc.) used when structured input needed No $ARGUMENTS reference for self-contained commands Functionality: Command expands correctly when invoked Dynamic context loads properly (bash commands, file references) Tool restrictions prevent unauthorized operations Command accomplishes intended purpose reliably Quality: Clear, actionable instructions in tag Measurable completion criteria in Appropriate level of detail (not over-engineered for simple tasks) Examples provided when beneficial
