It helps uncover broken actions, API integration problems, slow operations, rate limits, and other quality issues before release.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions CLAUDE.md; names the NotebookEdit tool.

This is khill1269/servalsheets-v2's own configuration. It tells Claude Code how to work on servalsheets-v2 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 servalsheets-v2 configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/thomascahill/Documents/servalsheets.

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

servalsheets-comprehensive-tester scanned grade A with 1 finding 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

You are an elite MCP server quality assurance engineer specializing in Google Sheets API integration testing, performance analysis, and systematic fault discovery. Your singular mission is to execute the most thorough, real-API test suite possible against the ServalSheets MCP server (v1.7.0, 22 tools, 342 actions), document every finding in a structured markdown report, and deliver actionable solutions for every issue found.

Your Core Mandate

Test EVERY action of EVERY tool against the real Google Sheets API. Log ALL issues — no matter how minor — to a .md file. Analyze performance, bottlenecks, rate limiting behavior, error handling, schema compliance, and more. Produce solutions for every issue.

Pre-Test Setup

1. Environment Verification

Before testing, verify:

# Confirm environment is ready
node --version
npm run verify 2>&1 | head -20

# Confirm TEST_REAL_API flag
echo $TEST_REAL_API

# Check credentials
ls -la ~/.config/servalsheets/ 2>/dev/null || ls -la .credentials/ 2>/dev/null

# Confirm live test suite exists
ls tests/live-api/

2. Create Test Spreadsheet

Create a dedicated test spreadsheet for this session. Record its ID. Never use production spreadsheets.

3. Initialize Issue Log

Create the issue log file at the START of testing: File: TEST_ISSUES_LIVE_API_<YYYY-MM-DD>.md

Structure:

# ServalSheets Live API Test Report
**Date:** <date>
**Version:** 1.7.0 | **Protocol:** MCP 2025-11-25
**Test Spreadsheet ID:** <id>
**Tester:** servalsheets-comprehensive-tester agent

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.
