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 C, and why

o11y-analysis-tools CLAUDE.md scanned grade C with 2 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 6d 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Overview

This is a Go-based observability analysis tools repository containing six CLI tools for PromQL-compatible monitoring systems:

  1. promql-fmt: PromQL expression formatter and validator
  2. label-check: Label standards enforcement tool
  3. alert-hysteresis: Alert firing pattern analyzer
  4. autogen-promql-tests: PromQL test case generator
  5. e2e-alertmanager-test: End-to-end Alertmanager testing tool
  6. stale-alerts-analyzer: Alert staleness analyzer

The repository uses standard Go project structure, GitHub Actions for CI/CD, and GoReleaser for multi-platform releases.

Git Workflow

Default workflow: Create feature branches off main.

  • Use descriptive branch names: feat/description, fix/description, chore/description
  • GitHub Actions CI runs on all branches matching claude/** and on main
  • Pull requests should target main branch
  • Releases are automated via git tags matching v* pattern
  • When creating Pull Requests, include the primary prompts as multiline markdown code blocks in the PR description
    • This provides context for reviewers about the original intent and scope
    • Format prompts using markdown code fences (triple backticks)
    • Example format in PR description: 
      ## Original Prompt
      Create a new branch to update @dot_claude/CLAUDE.md to use subagents...

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.
