What Detect Bottlenecks is
Detect Bottlenecks is a slash command published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”
A slash command is a reusable prompt saved as a markdown file and run by typing its name after a slash. In Claude Code, custom commands have been merged into skills: a file in .claude/commands/ and a skill folder in .claude/skills/ both create the same kind of command, and existing command files keep working.
Detect Bottlenecks gives you a repeatable way to run the same instructions without retyping them, optionally with arguments.
How to install Detect Bottlenecks
Claude Code
- Download detect-bottlenecks.md from the repository.
- Save it to ~/.claude/commands/ (all projects) or .claude/commands/ (one project). As a skill, you can instead save it as ~/.claude/skills/<name>/SKILL.md.
- Run it by typing / followed by its name.
Claude Cowork
- Turn the command into a skill: create a folder with the file saved as SKILL.md and zip it.
- In Customize → Skills, click +, then upload the ZIP.
- Run it from any task with / and the skill name.

Identify and resolve performance bottlenecks across the application stack.
Detection Areas
- CPU Bottlenecks: Computation-heavy operations
- Memory Bottlenecks: Memory allocation/deallocation issues
- I/O Bottlenecks: Disk and network operations
- Database Bottlenecks: Query performance issues
- Lock Contention: Synchronization overhead
- Resource Exhaustion: Connection pools, file descriptors
Process
- Analyze application architecture and data flow
- Identify potential bottleneck locations
- Review code for common bottleneck patterns
- Evaluate resource utilization
- Generate prioritized remediation plan
Output
Provide comprehensive report with:
- Identified bottlenecks with severity ratings
- Root cause analysis for each bottleneck
- Impact assessment on overall performance
- Specific remediation strategies with code examples
- Monitoring recommendations to prevent recurrence
- Priority order for addressing issues
Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
