Spaces

A workspace-management guide for spaces, which are separate areas for organizing product work and their layouts. It provides actions for listing, opening, creating, editing, and removing spaces.

In plain words
What is it for?
Use it to find a space, open it, create a new one, change its title or instructions, or remove it. Widget changes inside an open space are handled by a separate widget workflow.
Why use it?
It gives a consistent way to select and manage work areas without guessing their identifiers or editing configuration by hand. It also helps preserve the current space’s metadata and widget layout.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Spaces scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to Spaces — 14 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Use this skill for space selection and space.yaml work

transient

  • Available Spaces in _____transient lists spaces (id|title)↓
  • when a current space is open, Current Space Widgets summarizes the live widget layout for that space
  • after widget writes or reloads, Current Widget is the last edited widget envelope

main helpers

  • listSpaces()
  • openSpace(id)
  • createSpace({ title? })
  • removeSpace(id)
  • readSpace(id)
  • saveSpaceMeta({ id, title?, icon?, icon_color?, agent_instructions? })

space selection

  • listSpaces() returns plain objects. Available Spaces is the lightweight prompt readback with id|title rows
  • If the user already named a target space clearly, list spaces, match that visible title to an id, and use that id directly
  • Prefer the exact id returned by listSpaces() or shown in Available Spaces
  • Do not ask which space if the visible title match is already unique
  • Do not invent a different id when the current list already showed the right one

current-space handoff

  • widget creation or editing inside the current open space belongs to the auto-loaded space-widgets skill
  • if the request is about the current open space itself, stay on it instead of reopening it
  • use this skill for space CRUD, navigation, and space.yaml; use current-space widget helpers only for widget work

examples Loading the spaces list _javascript return await space.spaces.listSpaces()

Opening the selected space _javascript return await space.spaces.openSpace("space-7")

Creating a new space _javascript return await space.spaces.createSpace({ title: "Research" })

Reading the current space file _javascript return await space.spaces.readSpace("space-7")

Removing the selected space _javascript return await space.spaces.removeSpace("space-7")

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
