What is google-mcp CLAUDE.md?

Project instructions for building Google Chat features with a specification-first workflow. They explain how project-wide guidance and feature specifications are stored and how Claude Code commands track active work.

It is for developing features such as retrieving Google Chat thread messages or user details, managing project guidance, and checking the status of active specifications.

Feature work can become inconsistent when requirements, project rules, and progress are kept in different places. These instructions give the agent a defined path from requirements to implementation.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00693	$0.00693
Opus 5	$0.00347	$0.00347
Sonnet 5	$0.00139	$0.00139
Haiku 4.5	$0.00069	$0.00069

Security

Grade A, and why

google-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 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.

Claude Code Spec-Driven Development

Kiro-style Spec Driven Development implementation using claude code slash commands, hooks and agents.

Project Context

Paths

Steering: .kiro/steering/
Specs: .kiro/specs/
Commands: .claude/commands/

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

get-thread-messages: Enable users to retrieve messages from Google Chat threads
get-user-info: Retrieve username and display name for Google Chat users
Check .kiro/specs/ for active specifications
Use /kiro:spec-status [feature-name] to check progress

Development Guidelines

Think in English, generate responses in English

Workflow

Phase 0: Steering (Optional)

/kiro:steering - Create/update steering documents
/kiro:steering-custom - Create custom steering for specialized contexts

Note: Optional for new features or small additions. You can proceed directly to spec-init.

Phase 1: Specification Creation

/kiro:spec-init [detailed description] - Initialize spec with detailed project description
/kiro:spec-requirements [feature] - Generate requirements document
/kiro:spec-design [feature] - Interactive: "Have you reviewed requirements.md? [y/N]"
/kiro:spec-tasks [feature] - Interactive: Confirms both requirements and design review

Phase 2: Progress Tracking

/kiro:spec-status [feature] - Check current progress and phases

Development Rules

Consider steering: Run /kiro:steering before major development (optional for new features)
Follow 3-phase approval workflow: Requirements → Design → Tasks → Implementation
Approval required: Each phase requires human review (interactive prompt or manual)
No skipping phases: Design requires approved requirements; Tasks require approved design
Update task status: Mark tasks as completed when working on them
Keep steering current: Run /kiro:steering after significant changes
Check spec compliance: Use /kiro:spec-status to verify alignment

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.
