anime-persona-skills: Instructions file for Codex

AGENTS.md

anime-persona-skills AGENTS.md is an instructions file for Codex, OpenCode from chanhoan/anime-persona-skills. It costs 556 tokens per session, scanned A, original, MIT.

Repository instructions for anime-persona-skills, a collection of character-based skills for Claude Code. They describe how character instructions are organised, written, and checked when there is no build system.

In plain words
What is it for?
Use them to create a new character skill from the template, update its documentation, inspect the file structure, and validate the Markdown and layout.
Why use it?
They give contributors a repeatable way to add characters while keeping the skill files and human-readable documentation aligned. They also define naming, formatting, and testing expectations.

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

anime-persona-skills 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 11d 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.

Repository Guidelines

Project Structure & Module Organization

This repository is a Markdown collection of anime persona skills for Claude Code/ECC.

  • characters/<name>/SKILL.md contains the actual persona instructions loaded by the skill system.
  • characters/<name>/README.md explains the character skill for human readers.
  • template/ provides the starting structure for new character skills.
  • README.md lists available characters and installation examples.
  • CONTRIBUTING.md defines the expected character research and PR content.

When adding a character, copy template/ into characters/<lowercase-name>/ and update both files.

Build, Test, and Development Commands

There is no build step or package manager. Validate changes by reading rendered Markdown and checking file layout.

cp -r template/ characters/<character-name>/
rg --files
sed -n '1,220p' characters/<character-name>/SKILL.md

Use rg for fast inspection. Keep shell examples executable.

Coding Style & Naming Conventions

Write skill files in Markdown with YAML front matter at the top of each SKILL.md. Use lowercase kebab-case for skill and folder names, for example characters/marin/.

Persona text may be Korean or English, but keep technical instructions precise. Preserve:

  • character essence before catchphrases
  • user relationship dynamic
  • speech patterns and intensity levels
  • Auto-Clarity rules for security, destructive actions, and confusing sequences
  • boundaries for code, commits, PRs, and normal-mode exit

Avoid generic AI phrasing. Code, commands, and commit messages stay normal and professional.

Testing Guidelines

No automated tests are configured. Review each new or changed skill manually:

  • Confirm SKILL.md front matter has name and description.
  • Confirm activation and stop phrases are documented.
  • Confirm examples demonstrate each intensity level.
  • Confirm technical advice in examples is correct.
  • Confirm README.md matches the skill behavior.

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.
