It gives the coding assistant project-specific guidance so its work follows the repository's expected practices.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is JulesLiu390/PetGPT's own configuration. It tells Claude Code how to work on PetGPT 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 PetGPT 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

PetGPT CLAUDE.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 9d 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.

PetGPT

Communication

  • 与用户交流时使用中文

Tauri v2 desktop app (Rust backend + React/Vite frontend). An AI pet that participates in group chats (QQ/WeChat via MCP) with a social agent system.

Build & Dev

npm run tauri:dev        # dev mode (macOS/Linux)
npm run tauri:build      # production build
npm run dev              # frontend only (Vite)
npm run lint             # ESLint

Architecture

Frontend (src/)

  • src/pages/ — React pages. SocialPage.jsx is the main social agent UI.
  • src/utils/socialAgent.js — Core social agent loop: Intent (eval/plan) + Reply (send) + Observer + Fetcher layers per target (group/friend).
  • src/utils/socialPromptBuilder.js — Builds system prompts for Intent eval and Reply LLM calls.
  • src/utils/workspace/socialToolExecutor.js — Executes builtin tools (write_intent_plan, sticker, social_read/edit/write, history, etc.).
  • src/utils/llm/ — LLM abstraction. index.js routes to Rust backend (llmCall/llmStream) or JS adapters.
  • src/utils/mcp/toolExecutor.js — callLLMWithTools loop: handles tool calls, builtin vs MCP dispatch, stopAfterTool.
  • src/utils/tauri.js — Tauri invoke wrappers (workspaceRead, workspaceWrite, llmCall, etc.).

Rust backend (src-tauri/)

  • Handles LLM API calls, file I/O, MCP server management, and system tray.

Key Patterns

Social Agent Loop

Each target (group/friend) runs independent loops:

  • Fetcher — polls MCP for new messages, wakes Intent via _wake()
  • Intent loop — evaluates situation, calls social_edit then write_intent_plan(actions=[...])
  • Reply loop — woken by replyWakeFlag, calls send_message via MCP (stopped after first call via stopAfterTool)
  • Observer loop — periodic background analysis

Intent State

  • Stored per-session in social/{group|friend}/INTENT_{targetId}.md (workspace file)
  • Format: 【我刚做了】... 【群里情况】... 【我的判断】...
  • LLM writes it directly via social_edit before calling write_intent_plan
  • Read back at next eval via readIntentStateFile in system prompt

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.
