Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is rshade/finfocus's own configuration. It tells GitHub Copilot how to work on finfocus 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 finfocus 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

finfocus go-module.instructions.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 18d 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

Go Module Instructions

The go.mod file manages Go module dependencies and version requirements.

Go Version Management:

  • Current version: the go directive in this file
  • Compatibility: Ensure all dependencies support that version
  • Updates: Update version consistently across all documentation

Dependency Management:

  • Use semantic versioning for dependencies
  • Prefer stable, well-maintained packages
  • Minimize dependency footprint
  • Review dependencies for security vulnerabilities
  • Use go mod tidy to clean up unused dependencies

Module Organization:

  • Use proper module path
  • Include replace directives for local development
  • Maintain clean dependency tree
  • Document major dependency changes

Security Considerations:

  • Regularly audit dependencies for vulnerabilities
  • Use govulncheck for security scanning
  • Update dependencies to patch security issues
  • Review dependency licenses

Version Consistency:

  • Keep Go version in sync across:
    • go.mod
    • CI/CD workflows
    • Documentation files
    • Docker images
    • Development environment setup

Build Requirements:

  • Ensure dependencies compile with target Go version
  • Test builds with different Go versions when needed
  • Validate module compatibility
  • Check for deprecated dependencies

Local Development:

  • Use go mod download to fetch dependencies
  • Handle replace directives for local packages
  • Maintain consistent development environment
  • Document setup requirements

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.
