Sim product language, positioning, and tone guidelines
We split this constitution.mdc into the rules it gives an agent
10 rules. About 0 are common, 10 are distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈10
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 8
When editing user-facing copy (landing pages, docs, metadata, marketing), follow these rules.
- Distinctive: line 41
Confident, not loud: No exclamation marks or superlatives.
- Distinctive: line 42
Simple: If a 16-year-old can't understand the sentence, rewrite it.
- Distinctive: line 46
When describing Sim, always lead with the most differentiated claim:
- Distinctive: line 67
Never call Sim "just a workflow tool"
- Distinctive: line 68
Never compare only on integration count — we win on AI-native capabilities
- Distinctive: line 69
Never use "no-code" as the primary descriptor — say "visually, conversationally, or with code"
- Distinctive: line 70
Never promise unshipped features
- Distinctive: line 71
Never use jargon ("RAG", "vector database", "MCP") without plain-English explanation on public pages
- Distinctive: line 72
Avoid "agentic workforce" as a primary term — use "AI agents"
≈ “Common” is an estimate: at least 1 in 5 of the 6,350 Cursor rule files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

# Sim — Language & Positioning
When editing user-facing copy (landing pages, docs, metadata, marketing), follow these rules.
## Identity
Sim is the **AI workspace** where teams build and run AI agents. Not a workflow tool, not an agent framework, not an automation platform.
**Short definition:** Sim is the open-source AI workspace where teams build, deploy, and manage AI agents.
**Full definition:** Sim is the open-source AI workspace where teams build, deploy, and manage AI agents. Connect 1,000+ integrations and every major LLM to create agents that automate real work — visually, conversationally, or with code.
## Audience
**Primary:** Teams building AI agents for their organization — IT, operations, and technical teams who need governance, security, lifecycle management, and collaboration.
**Secondary:** Individual builders and developers who care about speed, flexibility, and open source.
## Required Language
| Concept | Use | Never use |
|---------|-----|-----------|
| The product | "AI workspace" | "workflow tool", "automation platform", "agent framework" |
| Building | "build agents", "create agents" | "create workflows" (unless describing the workflow module specifically) |
| Visual builder | "workflow builder" or "visual builder" | "canvas", "graph editor" |
| Mothership | "Mothership" (capitalized) | "chat", "AI assistant", "copilot" |
| Deployment | "deploy", "ship" | "publish", "activate" |
| Audience | "teams", "builders" | "users", "customers" (in marketing copy) |
| What agents do | "automate real work" | "automate tasks", "automate workflows" |
| Our advantage | "open-source AI workspace" | "open-source platform" |
## Tone
- **Direct.** Short sentences. Active voice. Lead with what it does.
- **Concrete.** Name specific things — "Slack bots, compliance agents, data pipelines" — not abstractions.
- **Confident, not loud.** No exclamation marks or superlatives.
- **Simple.** If a 16-year-old can't understand the sentence, rewrite it.
## Claim Hierarchy
When describing Sim, always lead with the most differentiated claim:
1. **What it is:** "The AI workspace for teams"
2. **What you do:** "Build, deploy, and manage AI agents"
3. **How:** "Visually, conversationally, or with code"
4. **Scale:** "1,000+ integrations, every major LLM"
5. **Trust:** "Open source. SOC2. Trusted by 100,000+ builders."
## Module Descriptions
| Module | One-liner |
|--------|-----------|
| **Mothership** | Your AI command center. Build and manage everything in natural language. |
| **Workflows** | The visual builder. Connect blocks, models, and integrations into agent logic. |
| **Knowledge Base** | Your agents' memory. Upload docs, sync sources, build vector databases. |
| **Tables** | A database, built in. Store, query, and wire structured data into agent runs. |
| **Files** | Upload, create, and share. One store for your team and every agent. |
| **Logs** | Full visibility, every run. Trace execution block by block. |
## What We Never Say
- Never call Sim "just a workflow tool"
- Never compare only on integration count — we win on AI-native capabilities
- Never use "no-code" as the primary descriptor — say "visually, conversationally, or with code"
- Never promise unshipped features
- Never use jargon ("RAG", "vector database", "MCP") without plain-English explanation on public pages
- Avoid "agentic workforce" as a primary term — use "AI agents"
## Vision
Sim becomes the default environment where teams build AI agents — not a tool you visit for one task, but a workspace you live in. Workflows are one module; Mothership is another. The workspace is the constant; the interface adapts.
Where files are headingNew Cursor rule files have more rules about planning and tracking tasks, and fewer about code style.
Of the Cursor rule files we read, the 3,978 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.
In this repository54 other files it gives its agents.

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
