example

example is a command for Claude Code from Linfee/spec-kit-cn. It costs 10 tokens per session (1,124 once invoked), scanned A, original, MIT.

An example command showing how to create a Spec Kit extension command, including configuration checks, settings, an external tool call, and result output.

In plain words
What is it for?
Use it as a starting point when documenting or implementing a command that depends on configuration and an MCP server tool.
Why use it?
It gives developers a concrete pattern for loading extension configuration, validating required values, and reporting success or errors.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

example 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 1mo 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.

用途

描述此命令的作用以及适用场景。

先决条件

列出使用此命令前的要求:

  1. 先决条件 1(例如 “MCP server configured”)
  2. 先决条件 2(例如 “Configuration file exists”)
  3. 先决条件 3(例如 “Valid API credentials”)

$ARGUMENTS

步骤

步骤 1:加载配置

从项目中加载扩展配置:

config_file=".specify/extensions/my-extension/my-extension-config.yml"

if [ ! -f "$config_file" ]; then
  echo "❌ Error: Configuration not found at $config_file"
  echo "Run 'specify-cn extension add my-extension' to install and configure"
  exit 1
fi

# Read configuration values
setting_value=$(yq eval '.settings.key' "$config_file")

# Apply environment variable overrides
setting_value="${SPECKIT_MY_EXTENSION_KEY:-$setting_value}"

# Validate configuration
if [ -z "$setting_value" ]; then
  echo "❌ Error: Configuration value not set"
  echo "Edit $config_file and set 'settings.key'"
  exit 1
fi

echo "📋 Configuration loaded: $setting_value"

步骤 2:执行主要操作

描述此步骤要做什么:

使用 MCP 工具执行主要操作:

  • Tool: example-mcp-server example_tool
  • Parameters: { "key": "$setting_value" }

这会调用 MCP server 工具来执行操作。

步骤 3:处理结果

处理结果并输出:

echo ""
echo "✅ Command completed successfully!"
echo ""
echo "Results:"
echo "  • Item 1: Value"
echo "  • Item 2: Value"
echo ""

步骤 4:保存输出(可选)

如果需要将结果保存到文件:

output_file=".specify/my-extension-output.json"

cat > "$output_file" <<EOF
{
  "timestamp": "$(date -u +"%Y-%m-%dT%H:%M:%SZ")",
  "setting": "$setting_value",
  "results": []
}
EOF

echo "💾 Output saved to $output_file"

配置参考

此命令使用 my-extension-config.yml 中的以下配置:

  • settings.key: 此设置的用途说明

    • Type: string
    • Required: Yes
    • Example: "example-value"
  • settings.another_key: 另一个设置的说明

    • Type: boolean
    • Required: No
    • Default: false
    • Example: true

环境变量

可以使用环境变量覆盖配置:

  • SPECKIT_MY_EXTENSION_KEY - 覆盖 settings.key
  • SPECKIT_MY_EXTENSION_ANOTHER_KEY - 覆盖 settings.another_key

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.

example is a command published in the GitHub repository Linfee/spec-kit-cn (708 stars, last pushed 2mo ago), licensed MIT. It adds 10 tokens to every session and 1,124 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
