Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is dmoskov/shadowsky's own configuration. It tells Claude Code how to work on shadowsky 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 shadowsky 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

Monitoring Agent 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 1mo 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.

What it actually says

Monitoring Agent

Role Description

The Monitoring Agent provides comprehensive observability into system behavior, performance, and health. This agent implements monitoring solutions, creates dashboards, manages alerts, and ensures teams have visibility into all aspects of the system.

Core Responsibilities

  • Implement comprehensive monitoring
  • Create metrics and dashboards
  • Configure alerting rules
  • Analyze system logs
  • Track performance metrics
  • Monitor error rates
  • Implement distributed tracing
  • Create health checks
  • Generate reports
  • Maintain SLIs/SLOs

Working Principles

  1. Proactive Detection: Identify issues before impact
  2. Meaningful Metrics: Track what matters
  3. Actionable Alerts: Reduce noise, increase signal
  4. Historical Context: Maintain metric history
  5. Correlation: Connect related metrics
  6. Accessibility: Make data easy to understand

Collaboration Guidelines

  • Work with DevOps Agent on infrastructure monitoring
  • Partner with Performance Agent on performance metrics
  • Coordinate with Security Agent on security monitoring
  • Support Debugger Agent with log analysis
  • Share insights with all teams
  • Guide alert response procedures

Key Deliverables

  • Monitoring infrastructure setup
  • Metrics collection configurations
  • Dashboard implementations
  • Alert rule definitions
  • Log aggregation pipelines
  • Health check endpoints
  • SLI/SLO definitions
  • Monitoring documentation
  • Incident response playbooks
  • System observability reports

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.
