AGENTS.md

jmcomic-ai AGENTS.md is an instructions file for Codex, OpenCode from hect0x7/jmcomic-ai. It costs 1,799 tokens per session, scanned A, original, MIT.

Repository guidance for agents developing JMComic AI, a project that turns a comic crawler into tools that AI agents can use.

In plain words
What is it for?
Researching the codebase and making agent-focused changes to services, MCP tools, documentation, and skill installation.
Why use it?
It explains the project structure, development principles, and where its core logic, agent interface, and skill management live.

This is hect0x7/jmcomic-ai's own configuration. It tells Codex and OpenCode how to work on jmcomic-ai 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 jmcomic-ai configures โ†’

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

jmcomic-ai AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories โ€” prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency โ€” 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.

AI Agent Development Guide for JMComic AI

This document provides instructions and best practices for AI Agents (like Antigravity) to develop, maintain, and extend the jmcomic-ai project.

๐ŸŽฏ Core Philosophy

The mission of this project is to transform the JMComic crawler into an AI-native cognitive asset.

  • Tools over Scripts: Don't just write scripts; build robust MCP tools that agents can use to reason and act.
  • Documentation as Code: Documentation (like SKILL.md) is the "brain" of the agent. It must be kept in sync with the implementation.
  • Self-Introspection: The project should expose its own schema and reference through MCP Resources.

๐Ÿ—๏ธ Architecture for Agents

  • src/jmcomic_ai/core.py: The "Brain". All business logic and tool implementations reside here in JmcomicService.
  • src/jmcomic_ai/mcp/server.py: The "Interface". Uses FastMCP to dynamically register methods from JmcomicService as MCP tools.
  • src/jmcomic_ai/skills/manager.py: The "Distributor". Owns platform-specific Agent Skills installation paths and safe install/uninstall behavior.
  • reference/jmcomic_src/: The "Knowledge Base". Contains the source code of the underlying jmcomic library. Always read this first when implementing new tools.

[!IMPORTANT] CRITICAL SOURCE CODE RULE Do NOT attempt to locate the jmcomic source code using python -c "import jmcomic; print(jmcomic.__file__)" or pip show. The installed version in site-packages is IRRELEVANT for development reference. You MUST strictly use the local copy in reference/jmcomic_src/ for all code analysis and logic extraction. Ignoring this rule leads to incorrect path assumptions and wasted steps.

When asked to add a new feature or tool, follow these steps:

1. Research & Discovery

  • STOP & READ: Go directly to reference/jmcomic_src/. Do not check installed packages.
  • Search reference/jmcomic_src/ to find the relevant logic in the base library.
  • For example, if adding a "favorite" feature, search for favorite in the reference code to see how JmcomicClient handles it.

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.
