openghost AGENTS.md

A set of project instructions for OpenGhost, a standalone toolkit for authorized security testing of web applications and servers. It defines the project boundary, skill layout, source paths, and use of its sandboxed tools.

In plain words
What is it for?
Use it when working on the OpenGhost skill package, sandbox launcher, engagement data, or related documentation and source files.
Why use it?
It keeps coding agents aligned with the repository’s security workflow and prevents them from running security tools directly on the host system.

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

openghost 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 2d 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 This Repo Is

OpenGhost is an original standalone Agent Skill for authorized web application and server integrity penetration testing. The repo packages skill instructions, reference methodology, evidence/reporting helpers, and a Docker-backed launcher that keeps security tooling out of the host environment.

The central design constraint is simple: agents provide reasoning and workflow control, while OpenGhost provides the sandboxed execution layer and structured engagement state.

Product Boundary

  • This repository owns the OpenGhost skill package and sandbox launcher.
  • Security tools must be executed through openghost, not directly on the host.
  • External research/reference directories are not runtime dependencies and should not be cited as OpenGhost source material.
  • Generated engagement data belongs under .openghost/ and should normally stay uncommitted.

Agent Skill Structure

OpenGhost follows the standard Agent Skill layout:

  • skills/openghost-skill/SKILL.md is the published skill entrypoint and operator workflow.
  • Keep SKILL.md focused and use progressive disclosure: short entrypoint instructions first, deeper details in references.
  • skills/openghost-skill/references/ contains deeper guidance that agents should load only when relevant.
  • skills/openghost-skill/scripts/ contains deterministic helpers and launcher implementation.
  • skills/openghost-skill/assets/ contains templates and reusable output files.
  • Do not duplicate large methodology content across files; link to the canonical reference instead.

Main Source Paths

  • skills/openghost-skill/SKILL.md - published skill entrypoint and operator workflow.
  • skills/openghost-skill/references/ - deeper guidance for modules, reporting, tooling, auth, and workflow.
  • skills/openghost-skill/references/modules/ - assessment modules such as surface mapping, session auth, access control, injection, APIs, browser policy, HTTP edge, business logic, and server integrity.
  • skills/openghost-skill/scripts/openghost.sh - canonical CLI and Docker sandbox implementation.
  • skills/openghost-skill/scripts/verify-toolchain.sh - runtime toolchain verification.
  • skills/openghost-skill/scripts/select-modules.py - module selection helper.
  • skills/openghost-skill/assets/ - templates for scope, auth, findings, and reports.
  • skills/openghost-skill/agents/ - compatibility notes for other coding agents.

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.
