live2d-add-motion-sample-web-ui: Instructions file for Codex

AGENTS.md

live2d-add-motion-sample-web-ui AGENTS.md is an instructions file for Codex, OpenCode from shinshin86/live2d-add-motion-sample-web-ui. It costs 8,713 tokens per session, scanned A, original, MIT.

A project guide for AI coding agents working on a web interface that adds motion to Live2D models using JSON files. It explains how to find, set up, inspect, edit, and test a model.

In plain words
What is it for?
Use it when adding or changing Live2D model motions, setting up a model from a folder or ZIP file, inspecting its parameters, and checking playback in the web interface.
Why use it?
It gives the agent a defined process for working with the model and reduces guesswork about files, commands, and checks.

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

live2d-add-motion-sample-web-ui AGENTS.md scanned grade A with 1 finding 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 3d 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.

AGENTS.md — Guide for AI Agents

A project that adds motions to a Live2D model using JSON only, with a WebUI to verify playback. This document is the working playbook for AI agents (Claude Code / Codex, etc.).

The typical request, and what to do

Assume the user does not know the internal steps. The typical request is just "Add motions to this model" (+ the path to the model's zip/folder). In that case, execute the following autonomously:

  1. Locate the model — if no path was given, search local-assets/ and the repository for *.model3.json. If nothing is found, ask the user where the model is (only the user knows that).
  2. Set up — python3 tools/setup_model.py <zip or folder>. A working copy is created under models/ and registered in model.config.json. Every tool and the WebUI read that config from then on.
  3. Analyze — python3 tools/analyze_model.py to learn the available parameters, their safe value ranges, the physics outputs (marked ★), and the base pose.
  4. Design motions — following the "Design rules" below, write motion-defs/<model>.py for this model. The model name is the model3.json file name without its extension (e.g. mao_pro.model3.json → motion-defs/mao_pro.py). See the bundled sample motion-defs/hiyori_pro_t11.py for the format. Parameter sets differ between models, so design from the analyze output instead of reusing another model's definitions. If a definitions file for this model already exists (e.g. the bundled Hiyori sample), reuse or extend it rather than writing a new one.
  5. Generate — python3 tools/gen_motions.py (generate + register into model3.json; idempotent). Referencing a parameter the model does not have fails here.
  6. Validate — fix issues until python3 tools/validate_motions.py exits 0.
  7. Visual check — take screenshots with tools/verify_browser.sh and confirm with your own eyes that the expressions and poses look right (if the character stays in the base pose, playback failed).
  8. Hand over — start python3 tools/serve.py (add --port N if 8765 is taken) and tell the user to check http://localhost:8765.

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.
