Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is fantasieleven-code/callout's own configuration. It tells Claude Code how to work on callout 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 callout configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/alice/projects/my-app/src/auth.ts.

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

callout 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 2mo 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.

Callout — AI Co-founder for 0→1 Builds

What is this

MCP Server,非技术创始人的AI副驾驶。通过多视角审查、阶段引导、产品质疑帮用户发现"不知道该问的问题"。所有发现汇入 todo list 统一管理。

Product Context

目标用户: 用AI代替工程团队的非技术创始人。用Cursor/Claude Code/Kimi Code让AI写代码,但没有CTO/产品经理帮他把关方向。

核心理念:

  1. 五视角帮用户发现盲区(包括专利/合规/部署这些从没想过的问题)
  2. 发现必须变成行动 → 所有工具输出汇入todo list
  3. 不需要主动调用 → CLAUDE.md/.cursorrules规则自动触发
  4. Callout不调LLM → 只组装prompt,让宿主执行,零API成本

Current Status

V0.5.1: 16 MCP tools, 142 tests, npm published 路线图: 见 TODO.md 和 docs/roadmap.md 技术架构: 见 docs/architecture.md

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.
