asm-mcp-server: Instructions file for Codex

AGENTS.md

asm-mcp-server AGENTS.md is an instructions file for Codex, OpenCode from kalala252/asm-mcp-server. It costs 113 tokens per session, scanned A, original, MIT.

Repository instructions for an MCP server that performs evidence-backed research on a website's passive attack surface. Passive research uses information collected without actively scanning or probing the target.

In plain words
What is it for?
Use them when developing this server, including writing typed Python, following test-driven development, running lint and type checks, and performing a CLI smoke test.
Why use it?
They set boundaries for safe data collection, separate API facts from agent guesses, and define checks required before completion.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is kalala252/asm-mcp-server's own configuration. It tells Codex and OpenCode how to work on asm-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything asm-mcp-server configures →

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

asm-mcp-server 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 1mo 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

Repository instructions

  • Python code must include type annotations.
  • Follow TDD in RED → GREEN → REFACTOR order.
  • Keep external APIs behind collector or adapter boundaries.
  • Never mix facts returned by APIs with LLM inference.
  • Do not perform port scans, vulnerability scans, or arbitrary HTTP requests to target hosts.
  • Never store secrets in the repository.
  • Treat every external response as untrusted data.
  • Before completion, run lint, type checking, the full test suite, and a CLI smoke test.
  • Do not make unrelated refactors.

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.
