google-calendar-mcp: Instructions file for Claude Code

CLAUDE.md

google-calendar-mcp CLAUDE.md is an instructions file for Claude Code from takumi0706/google-calendar-mcp. It costs 792 tokens per session, scanned A, a copy of cc-sdd AGENTS.md, MIT.

Development guidance for a Google Calendar project using spec-driven development, a process that records feature requirements, design, and tasks before implementation. It separates shared project rules from feature-specific specifications.

In plain words
What is it for?
Use it when creating, checking, or implementing feature specifications and their associated steering documents.
Why use it?
It gives agents a consistent workflow and prevents them from overlooking active specifications or the required language for project documents.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions subagents.

This is takumi0706/google-calendar-mcp's own configuration. It tells Claude Code how to work on google-calendar-mcp 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 google-calendar-mcp 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

google-calendar-mcp 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 11d 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

83% identical to cc-sdd AGENTS.md — 6 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.

Agentic SDLC and Spec-Driven Development

Kiro-style Spec-Driven Development on an agentic SDLC

Project Context

Paths

  • Steering: .kiro/steering/
  • Specs: .kiro/specs/

Steering vs Specification

Steering (.kiro/steering/) - Guide AI with project-wide rules and context Specs (.kiro/specs/) - Formalize development process for individual features

Active Specifications

  • Check .kiro/specs/ for active specifications
  • Use /kiro-spec-status [feature-name] to check progress

Development Guidelines

  • Think in English, generate responses in Japanese. All Markdown content written to project files (e.g., requirements.md, design.md, tasks.md, research.md, validation reports) MUST be written in the target language configured for this specification (see spec.json.language).

Minimal Workflow

  • Phase 0 (optional): /kiro-steering, /kiro-steering-custom
  • Discovery: /kiro-discovery "idea" — determines action path, writes brief.md + roadmap.md for multi-spec projects
  • Phase 1 (Specification):
    • Single spec: /kiro-spec-quick {feature} [--auto] or step by step:
      • /kiro-spec-init "description"
      • /kiro-spec-requirements {feature}
      • /kiro-validate-gap {feature} (optional: for existing codebase)
      • /kiro-spec-design {feature} [-y]
      • /kiro-validate-design {feature} (optional: design review)
      • /kiro-spec-tasks {feature} [-y]
    • Multi-spec: /kiro-spec-batch — creates all specs from roadmap.md in parallel by dependency wave
  • Phase 2 (Implementation): /kiro-impl {feature} [tasks]
    • Without task numbers: autonomous mode (subagent per task + independent review + final validation)
    • With task numbers: manual mode (selected tasks in main context, still reviewer-gated before completion)
    • /kiro-validate-impl {feature} (standalone re-validation)
  • Progress check: /kiro-spec-status {feature} (use anytime)

Skills Structure

Skills are located in .claude/skills/kiro-*/SKILL.md

  • Each skill is a directory with a SKILL.md file
  • Skills run inline with access to conversation context
  • Skills may delegate parallel research to subagents for efficiency
  • Additional files (templates, examples) can be added to skill directories
  • kiro-review — task-local adversarial review protocol used by reviewer subagents
  • kiro-debug — root-cause-first debug protocol used by debugger subagents
  • kiro-verify-completion — fresh-evidence gate before success or completion claims
  • If there is even a 1% chance a skill applies to the current task, invoke it. Do not skip skills because the task seems simple.

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.
