playfab-mcp-server: Command for Claude Code

.claude/commands/speckit.specify.md

speckit.specify is a command for Claude Code from akiojin/playfab-mcp-server. It costs 19 tokens per session (2,513 once invoked), scanned A, a copy of specify, MIT.

A command that turns a natural-language feature description into a feature specification, including its actors, actions, data, and constraints.

In plain words
What is it for?
Use it when starting or updating a feature so the project has a structured specification based on the user's description.
Why use it?
It gives development work a written definition before implementation begins. It also creates a unique specification ID without creating a new branch.

Command for Claude Code

Written for Claude Code: $ARGUMENTS substitution.

This is akiojin/playfab-mcp-server's own configuration. It tells Claude Code how to work on playfab-mcp-server 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 playfab-mcp-server 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

speckit.specify 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 8d 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.

Origin

This is a copy

69% identical to specify — 213 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

概要

/speckit.specify の後にユーザーが入力したテキスト機能の説明です。以下に文字通り $ARGUMENTS と表示されていても、この会話で常に利用可能であると想定してください。空のコマンドを提供した場合を除き、ユーザーに繰り返し尋ねないでください。

機能の説明が与えられた場合、以下を実行します:

  1. SPEC IDを生成(ブランチは作成しない):

    a. まず、すべてのリモートブランチをフェッチして最新情報を取得します:

    git fetch --all --prune
    

    b. スクリプトを実行して新しいSPEC IDを生成します(--no-branch オプションを必ず指定): .specify/scripts/bash/create-new-feature.sh --json --no-branch "$ARGUMENTS"

    • 例: .specify/scripts/bash/create-new-feature.sh --json --no-branch "ユーザー認証を追加"

    重要:

    • --no-branch オプション: ブランチを作成せず、現在のブランチで作業を続けます(worktree設計思想に準拠)
    • このスクリプトは機能ごとに1回だけ実行する必要があります
    • JSONは端末に出力として提供されます - 探しているコンテンツを取得するために常にそれを参照してください
    • JSON出力にはBRANCH_NAME、SPEC_FILE、SPEC_IDが含まれます
    • スクリプトは自動的に一意のSPEC ID(SPEC-xxxxxxxx形式)を生成します
    • シングルクォートを含む引数("I'm Groot"など)の場合は、エスケープ構文を使用: 例 'I'''m Groot'(または可能であればダブルクォート: "I'm Groot")
  2. Load .specify/templates/spec-template.md to understand required sections.

  3. Follow this execution flow:

    1. Parse user description from Input If empty: ERROR "No feature description provided"
    2. Extract key concepts from description Identify: actors, actions, data, constraints
    3. For unclear aspects:
      • Make informed guesses based on context and industry standards
      • Only mark with [NEEDS CLARIFICATION: specific question] if:
        • The choice significantly impacts feature scope or user experience
        • Multiple reasonable interpretations exist with different implications
        • No reasonable default exists
      • LIMIT: Maximum 3 [NEEDS CLARIFICATION] markers total
      • Prioritize clarifications by impact: scope > security/privacy > user experience > technical details
    4. Fill User Scenarios & Testing section If no clear user flow: ERROR "Cannot determine user scenarios"
    5. Generate Functional Requirements Each requirement must be testable Use reasonable defaults for unspecified details (document assumptions in Assumptions section)
    6. Define Success Criteria Create measurable, technology-agnostic outcomes Include both quantitative metrics (time, performance, volume) and qualitative measures (user satisfaction, task completion) Each criterion must be verifiable without implementation details
    7. Identify Key Entities (if data involved)
    8. Return: SUCCESS (spec ready for planning)

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.
