What is agents AGENTS.md?

Repository instructions for developing AnomalyArmor agents, including the structure of its skills and MCP server. An MCP server lets an AI agent call tools exposed by another program.

Guiding work on data-connection, monitoring, alerts, analysis, question-answering, onboarding skills, and their supporting MCP server.

It helps contributors understand where features belong and how the repository separates reusable skills from server code.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00956	$0.00956
Opus 5.5	$0.00382	$0.00382
Sonnet 5.5	$0.00191	$0.00191
Haiku 4.5	$0.00096	$0.00096

Security

Grade A, and why

agents AGENTS.md 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 2mo 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.

Architecture

Skills vs MCP Server

These are independent delivery mechanisms:

Skills: Markdown instructions that tell Claude to write Python code using the SDK directly. Used via /armor:status, /armor:alerts, etc.
MCP Server: Structured tools for any MCP client (Claude Code, Cursor, etc.). Provides programmatic access to the SDK.

Both use the same underlying anomalyarmor Python SDK but can be used independently.

Skill Format

Skills use YAML frontmatter in skills/<name>/SKILL.md:

---
name: armor-status
description: Check data health, alerts, freshness issues, schema changes.
hooks:
  PreToolUse:
    - matcher: "Bash"
      hooks:
        - type: command
          command: "python ${CLAUDE_PLUGIN_ROOT}/scripts/ensure-auth.py"
          once: true

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.
