Use when complex problems require systematic step-by-step reasoning with ability to revise thoughts, branch into alternative approaches, or dynamically adjust scope. Ideal for multi-stage analysis, design planning, problem decomposition, or tasks with initially unclear scope.

Render Mermaid graph/flowchart and sequenceDiagram as terminal text via ascii.sh. Use for flowcharts, sequence diagrams, Mermaid examples, or ASCII diagrams.
Create Excalidraw diagram JSON files that make visual arguments. Use when the user wants to visualize workflows, architectures, or concepts.
Browser automation, debugging, and performance analysis using Puppeteer CLI scripts. Use for automating browsers, taking screenshots, analyzing performance, monitoring network traffic, web scraping, form automation, and JavaScript debugging.
Help with Neovim development, configuration, plugin setup, plugin install locations, and runtime inspection. Use this skill when the user asks to inspect or modify Neovim config files, plugin specs, plugin installation directories, keymaps, autocmds, options, LSP setup, lazy.nvim configuration, runtime files, help docs, or a currently running Neovim instance via RPC/socket. Works both for config-repo editing and live Neovim session debugging, using `$NVIM` inside a Neovim terminal or `$NVIM_SOCKET_PATH` in a normal terminal.
Create diagrams and visualizations using Mermaid.js v11 syntax. Use when generating flowcharts, sequence diagrams, class diagrams, state diagrams, ER diagrams, Gantt charts, user journeys, timelines, architecture diagrams, or any of 24+ diagram types. Supports JavaScript API integration, CLI rendering to SVG/PNG/PDF, theming, configuration, and accessibility features. Essential for documentation, technical diagrams, project planning, system architecture, and visual communication.
Create or update Claude skills. Use for new skills, skill references, skill scripts, optimizing existing skills, extending Claude's capabilities.

Enables structured problem-solving through iterative reasoning with revision and branching capabilities.
Use mcp__reasoning__sequentialthinking when:
Don't use for: Simple queries, direct facts, or single-step tasks.
The MCP tool mcp__reasoning__sequentialthinking accepts these parameters:
thought (string): Current reasoning stepnextThoughtNeeded (boolean): Whether more reasoning is neededthoughtNumber (integer): Current step number (starts at 1)totalThoughts (integer): Estimated total steps neededisRevision (boolean): Indicates this revises previous thinkingrevisesThought (integer): Which thought number is being reconsideredbranchFromThought (integer): Thought number to branch frombranchId (string): Identifier for this reasoning branch1. Start with initial thought (thoughtNumber: 1)
2. For each step:
- Express current reasoning in `thought`
- Estimate remaining work via `totalThoughts` (adjust dynamically)
- Set `nextThoughtNeeded: true` to continue
3. When reaching conclusion, set `nextThoughtNeeded: false`
// First thought
{
thought: "Problem involves optimizing database queries. Need to identify bottlenecks first.",
thoughtNumber: 1,
totalThoughts: 5,
nextThoughtNeeded: true
}
// Second thought
{
thought: "Analyzing query patterns reveals N+1 problem in user fetches.",
thoughtNumber: 2,
totalThoughts: 6, // Adjusted scope
nextThoughtNeeded: true
}
// ... continue until done
