spaces

spaces is a command for coding agents from aws/agent-toolkit-for-aws. It costs 11 tokens per session (215 once invoked), scanned A, original, Apache-2.0.

A command for listing configured AWS AgentSpaces and summarizing their linked accounts and knowledge. An AgentSpace is an AWS agent environment connected to accounts and available runbooks or services.

In plain words
What is it for?
Use it to list spaces, inspect their attached AWS account IDs, ask what each space can access, and create routing guidance when several spaces are available.
Why use it?
It replaces manual checking with a consistent overview of which spaces and AWS resources are available under the current authentication.

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 4d 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.

What it actually says

  1. Call aws_devops_agent__list_agent_spaces() — get all spaces accessible with current auth.
    • Bearer token auth: Returns only the single space the token is scoped to.
    • SigV4 auth: Returns all spaces in the account.
  2. For each space, call aws_devops_agent__list_associations(agent_space_id="SPACE_ID") to see attached AWS accounts.
  3. For each space, probe its knowledge: aws_devops_agent__chat(message="Summarize the AWS services and runbooks you have access to. One-paragraph answer.", agent_space_id="SPACE_ID").
  4. Print a table: name, agentSpaceId, attached account IDs, one-line capability summary.
  5. If more than one space exists and no routing guide in the workspace (e.g. .claude/aws-agents-for-devsecops.md, AGENTS.md, or per-project notes), offer to write one.
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.
