What it does
Cognitive Pattern is an agent skill from ruvnet/ruflo. Define and manage cognitive patterns for agent reasoning and decision-making
Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Model Context Protocol. The repository describes itself as: 🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory…. The licence is MIT.
Example prompts
- “/cognitive-pattern”
Requirements
- Pre-approved tools (allowed-tools): mcp__plugin_ruflo-core_ruflo__daa_cognitive_pattern, mcp__plugin_ruflo-core_ruflo__daa_workflow_create, mcp__plugin_ruflo-core_ruflo__daa_workflow_execute, mcp__plugin_ruflo-core_ruflo__daa_knowledge_share, mcp__plugin_ruflo-core_ruflo__daa_learning_status, Bash
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Define pattern — call mcpplugin_ruflo-core_ruflodaa_cognitive_pattern with the pattern structure and triggers
- Create workflow — call mcpplugin_ruflo-core_ruflodaa_workflow_create to embed the pattern in an executable workflow
- Execute — call mcpplugin_ruflo-core_ruflodaa_workflow_execute to run the cognitive workflow
- Evaluate — call mcpplugin_ruflo-core_ruflodaa_learning_status to see how the pattern performs
- Share — call mcpplugin_ruflo-core_ruflodaa_knowledge_share to propagate successful patterns
What it can do on your machine
Read from SKILL.md and the folder at commit de590e1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
mcp__plugin_ruflo-core_ruflo__daa_cognitive_patternmcp__plugin_ruflo-core_ruflo__daa_workflow_createmcp__plugin_ruflo-core_ruflo__daa_workflow_executemcp__plugin_ruflo-core_ruflo__daa_knowledge_sharemcp__plugin_ruflo-core_ruflo__daa_learning_statusBash
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cognitive Pattern loads about 384 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 115 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety

The automated check noted patterns worth knowing about, such as sudo or a known installer.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Cognitive Pattern
Define cognitive patterns that guide agent reasoning and decision-making.
When to use
When you want to codify reasoning strategies, decision trees, or problem-solving approaches that agents can use and improve over time.
Steps
- Define pattern — call
mcp__plugin_ruflo-core_ruflo__daa_cognitive_patternwith the pattern structure and triggers - Create workflow — call
mcp__plugin_ruflo-core_ruflo__daa_workflow_createto embed the pattern in an executable workflow - Execute — call
mcp__plugin_ruflo-core_ruflo__daa_workflow_executeto run the cognitive workflow - Evaluate — call
mcp__plugin_ruflo-core_ruflo__daa_learning_statusto see how the pattern performs - Share — call
mcp__plugin_ruflo-core_ruflo__daa_knowledge_shareto propagate successful patterns
Pattern types
- Decision trees — structured if/then reasoning
- Chain of thought — step-by-step problem decomposition
- Analogy mapping — solve new problems by referencing similar solved ones
- Consensus patterns — multi-perspective evaluation before deciding

Questions about Cognitive Pattern
What does Cognitive Pattern do?
Define and manage cognitive patterns for agent reasoning and decision-making. Cognitive Pattern is an agent skill from ruvnet/ruflo.
How do I install Cognitive Pattern in Claude Code?
Run `npx skills add ruvnet/ruflo --skill cognitive-pattern -a claude-code`. Or copy the skill folder (plugins/ruflo-daa/skills/cognitive-pattern in ruvnet/ruflo) into .claude/skills/cognitive-pattern in your project. Claude Code loads it when a task matches its description.
How do I install Cognitive Pattern in Codex?
Run `npx skills add ruvnet/ruflo --skill cognitive-pattern -a codex`. Or copy the skill folder (plugins/ruflo-daa/skills/cognitive-pattern in ruvnet/ruflo) into .agents/skills/cognitive-pattern in your project. Codex loads it when a task matches its description.
Can I use Cognitive Pattern in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ruvnet/ruflo --skill cognitive-pattern -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cognitive-pattern, .gemini/skills/cognitive-pattern, .github/skills/cognitive-pattern and .opencode/skills/cognitive-pattern in your project.
What does Cognitive Pattern need to run?
SKILL.md names no scripts, command-line tools or credentials: Cognitive Pattern is instructions for the agent only. Its frontmatter pre-approves these tools: mcp__plugin_ruflo-core_ruflo__daa_cognitive_pattern, mcp__plugin_ruflo-core_ruflo__daa_workflow_create, mcp__plugin_ruflo-core_ruflo__daa_workflow_execute, mcp__plugin_ruflo-core_ruflo__daa_knowledge_share, mcp__plugin_ruflo-core_ruflo__daa_learning_status, Bash.
Does Cognitive Pattern access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Cognitive Pattern safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Cognitive Pattern use?
Cognitive Pattern is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Cognitive Pattern use?
About 384 tokens (SKILL.md is roughly 1.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Cognitive Pattern?
Skills that share tags, products or a category with Cognitive Pattern: MCP Server Builder (anthropics/skills, 180k stars), MCP Server Builder (shareAI-lab/learn-claude-code, 78k stars), MCP Integration for Plugins (anthropics/claude-plugins-official, 37k stars) and Figma use_figma Plugin API Rules (warpdotdev/warp, 65k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
