code-quest: Skill for Claude Code

.claude/skills/fake-summoner-server/SKILL.md

fake-summoner-server is a skill for Claude Code from recca0120/code-quest. It costs 65 tokens per session (3,187 once invoked), scanned A, original, MIT.

A server-side test harness that simulates a connected application window, a command-line process, services, and an in-memory database. Socket.io is a library for real-time connections between clients and servers.

In plain words
What is it for?
Use it when writing or debugging server tests for socket handlers, channels, pipelines, databases, or CLI processes; client tests use a separate harness.
Why use it?
It lets server tests exercise realistic connections and workflows without depending on a real database or external command-line process. It also provides the project’s expected dependency-injection setup.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is recca0120/code-quest's own configuration. It tells Claude Code how to work on code-quest 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 code-quest configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { createFakeSummoner } from '../test/index.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

fake-summoner-server 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.

FakeSummoner — Server Tests

核心概念

FakeSummoner = 一個 測試用的 window/連線,同時擁有:

  • 真的 socket.io client(連到測試用 FakeServer)
  • 一個 FakeClaude(模擬 CLI 過程)
  • FilesystemService / GitService 的記憶體 fake 實作

每個 FakeSummoner 代表「一個 UI window」。多 window 測試建立多個 summoner 共用同一 server。

Import 來源

東西 從哪 import
createFakeSummoner / createFakeServer / createTestContainer ../test/index(server 專用版,會 wire DI container)
segments as s @code-quest/summoner/test

Server tests 一律從 ../test/index.ts import — 那是包過 DI container 的版本。@code-quest/summoner/test 的同名 export 是 summoner base 版,給 summoner package 本身測試用。

最小 Setup

import { segments as s } from '@code-quest/summoner/test';
import { createFakeSummoner } from '../test/index.ts';

const claude = createFakeSummoner().claude();
const channelId = await claude.initialize();

initialize() 跑完整 CLI 啟動流程:spawn → ready → init segment。

含 DI container(存取 services)

import { createFakeServer, createFakeSummoner, createTestContainer } from '../test/index.ts';

async function setup(sessionId = 'cli-sess') {
  const container = createTestContainer();
  const server = createFakeServer(container);
  const summoner = createFakeSummoner(server);
  const claude = summoner.claude();
  const channelId = await claude.initialize(s.init(sessionId));
  return { container, claude, channelId };
}

FakeSummoner API

const summoner = createFakeSummoner(server);

summoner.claude()                  // lazy-init FakeClaude
summoner.socket                    // FakeSocket(注入到 SocketProvider)
summoner.filesystem()              // FakeFilesystemService
summoner.git()                     // FakeGitService(可 undefined)
summoner.openspec()                // FakeOpenspecService(可 undefined)
summoner.pluginCli()               // FakePluginCliService(可 undefined)
summoner.connected                 // boolean
summoner.disconnect()

await summoner.send<T>(event, payload)     // 透過 socket 送(等 ack)
summoner.receivedEvents()                  // 收到的所有 server → client events
summoner.receivedEvents('session:init')    // 過濾特定 event
summoner.sentEvents()                      // 所有 client → server emits
summoner.sentEvents('session:launch')      // 過濾特定 sent event
summoner.on(event, fn)                     // subscribe
summoner.holdEmit(event)                   // 攔截下一次 emit 的 ACK(見下節)

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.
