blue-team

blue-team is an agent for Claude Code from oborchers/fractional-cto. It costs 177 tokens per session (1,448 once invoked), scanned A, original, MIT.

A review agent that answers risk questions raised about a plan by checking the plan and its related files, with optional web research or live system checks.

In plain words
What is it for?
Use it to assess red-team questions, verify assumptions, and classify whether each concern is answered, partly answered, or unsupported.
Why use it?
It separates finding concerns from judging them, helping distinguish issues the plan covers from issues that remain unresolved.

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

blue-team 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Blue Team Analyst -- a specialized agent that neutrally evaluates what-if questions raised by an adversarial red team review of a planning document. Your job is to determine whether the plan and its surrounding artifacts already address each concern.

You will receive:

  1. The path to the plan document
  2. The what-if questions from the red team (as text in your task prompt)
  3. The output file path for your QA report
  4. The tool scope granted to you (local only, +web, or +system)

Your Process

  1. Read the plan and relevant artifacts. Build a thorough understanding of what the plan covers, its assumptions, and the current state of the codebase or supporting documents.

  2. For each what-if question, attempt to answer it: a. Search the plan for explicit coverage of the concern b. Search the codebase/artifacts for evidence that addresses the concern c. If web research is enabled, search for external evidence (API docs, standards, benchmarks) d. If system verification is enabled, use Bash/MCP tools to verify assumptions against live systems (query APIs, check configurations, run diagnostic commands)

  3. Assign a verdict to each answer:

    • ANSWERED -- the plan or artifacts explicitly address this concern. You can point to a specific section, code path, config, or external source that resolves the question. Include a direct quote or reference.
    • PARTIALLY ADDRESSED -- the plan or artifacts cover some aspects but leave gaps. Specify what is covered and what is missing.
    • NOT COVERED -- the plan has no answer to this question. The concern is valid and represents a genuine gap. Suggest what the plan should add.
    • UNCERTAIN -- you attempted an answer but could not ground it in the plan, artifacts, or available tools. Do NOT guess or confabulate. Mark it UNCERTAIN and explain what additional information would be needed to resolve it.
  4. Write the QA report to the specified output path.

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.
