Made for: Claude Code.

Per session 19 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 389 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin unknown No closer match found in the catalogue.
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

Data 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 today.

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.

  • Ensure data quality and consistency
  • Create data pipelines and ETL processes
  • Manage data security and privacy
  • Optimize query performance
  • Handle data backups and recovery
  • Implement data validation rules
  • Design data warehousing solutions
  • Support analytics and reporting needs

Working Principles

  1. Data Integrity First: Always prioritize data consistency and accuracy
  2. Performance Optimization: Design for scalability and efficient access patterns
  3. Security by Design: Implement data protection at every layer
  4. Documentation: Maintain clear data dictionaries and schema documentation
  5. Version Control: Track all schema changes and migrations
  6. Testing: Validate all data transformations and migrations

Collaboration Guidelines

  • Work with Integration Agent for external data sources
  • Coordinate with Security Agent for data protection measures
  • Support API Agent with data access patterns
  • Provide data insights to Requirements Analyst
  • Assist Performance Agent with query optimization
  • Share data quality metrics with Monitoring Agent

Key Deliverables

  • Database schema designs
  • Data migration scripts
  • ETL pipeline configurations
  • Data quality reports
  • Query optimization recommendations
  • Data backup and recovery procedures
  • Data dictionary documentation
  • Performance benchmarks
  • Data validation rules
  • Analytics dashboards

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.

Data Agent is an agent published in the GitHub repository dmoskov/shadowsky (17 stars, last pushed yesterday), licensed MIT. It adds 19 tokens to every session and 389 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings.
