monitor CLAUDE.md

Repository instructions for ntppool/monitor, a distributed system that checks NTP Pool time servers from many monitoring locations.

In plain words
What is it for?
Understanding the monitor’s agent, API, and scoring components. They also guide task breakdown, formatting Go code, running tests, building affected packages, and checking code quality.
Why use it?
They give coding agents the project structure, task-management rules, and checks required before committing changes. NTP is the network protocol computers use to keep their clocks aligned.

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

monitor 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 2d 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.

LLM_CODING_AGENT.md

This file provides guidance to Claude Code (claude.ai/code) and other LLM-based coding agents when working with code in this repository.

Project Overview

The NTP Pool Monitor is a distributed monitoring system for the NTP Pool project. It consists of three main components:

  • ntppool-agent - Monitoring client that runs on distributed nodes
  • monitor-api - Central API server for coordination and configuration
  • monitor-scorer - Processes monitoring results and calculates server scores

Task Management

Use TodoWrite/TodoRead tools for complex multi-step tasks (3+ steps) or when user explicitly requests todo management.

Best Practices:

  • Break down complex tasks into specific, actionable items
  • Mark tasks in_progress before starting work (only ONE at a time)
  • Complete tasks immediately after finishing
  • Only mark completed when fully accomplished

Pre-Commit Checklist

MANDATORY before any git commit:

  1. Run gofumpt -w on all changed .go files
  2. Run make test to ensure all tests pass
  3. Verify compilation with go build for affected packages
  4. Run lint tools if available (golangci-lint run, go vet ./...)
  5. Check for race conditions and proper error handling

Never commit changes unless explicitly asked by the user. NEVER USE git add -A - always use explicit, targeted git staging.

Development Commands

make tools          # Install required development tools
make generate       # Generate all code (runs sqlc then go generate ./...)
make build          # Build all components
make test           # Run comprehensive test suite

Code Generation

Never edit generated files directly - changes will be lost on regeneration.

Generated file patterns:

  • *.pb.go - Protocol buffer generated files
  • *.sql.go - sqlc generated database code
  • otel.go - OpenTelemetry instrumentation wrappers
  • *_string.go - Enum string methods
  • Files in api/pb/ and gen/ directories

Changes

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.
