Slash Commands (Skills & Prompts)

Typing / in a Chat Node input opens the slash menu — a quick keyboard-driven way to configure the conversation and pull in your reusable prompt library.

---

What's in the menu

The slash menu has three groups:

1. MCP server quick-toggles — enable or disable your configured MCP servers for this conversation

2. Reasoning presets — Reasoning: Low, Reasoning: Medium, Reasoning: High, Reasoning: Max, for models that support extended thinking (see Models & Providers)

3. Skills & prompts — your local library of reusable markdown prompts and agent skills

Keep typing after / to filter the list, then press Enter to select.

Where the library lives on disk

Your skills and prompts are plain files you own:

• Prompts — any .md file in ~/SlashspaceOS/.prompts. Optional frontmatter name: and description: control how it appears in the menu; otherwise the filename is used.
• Skills — folders containing a SKILL.md file under ~/.agents/skills. This is the cross-tool agent-skills convention, so skills you already use with tools like Claude Code appear here automatically.

---

Using a skill or prompt

1. Type / and select an entry from the skills & prompts group

2. A chip is inserted into your message — you can keep typing around it

3. On send, the file's full content is injected into the message for the model, wrapped in a Skill or Prompt tag

A single referenced file over 120,000 characters errors on send. The total expanded message is capped at 400,000 characters.

If the file behind a chip has been deleted or renamed, sending fails with Missing slash command reference… — remove the chip and re-add it from the menu.

Creating your own prompts

1. Create a markdown file in ~/SlashspaceOS/.prompts, for example summarize-meeting.md:

   ---
   name: Summarize meeting
   description: Turn raw notes into decisions and action items
   ---
   
   Summarize the following meeting notes. List decisions made,
   open questions, and action items with owners.

2. Type / in any chat — the new prompt appears in the menu immediately, no restart needed

---

Use cases

• Repeatable workflows: a /summarize-meeting prompt you run on pasted notes every week, instead of retyping instructions.
• Shared skills across tools: the same ~/.agents/skills folders power both this app and Claude Code, so one skill library serves your whole toolkit.
• Fast conversation setup: / → toggle an MCP server → / → Reasoning: High, all without leaving the keyboard.
• Prompt libraries in version control: keep ~/SlashspaceOS/.prompts in a git repo and sync your best prompts across machines.
