Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is ani3198/threadbase's own configuration. It tells GitHub Copilot how to work on threadbase 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 threadbase 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

threadbase copilot-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 2mo 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

Threadbase Instructions for GitHub Copilot

  • Read .ai/generated/index.md before making important changes.
  • If .ai/generated/index.md is missing or empty, generate it from scratch using .ai/prompts/generate_index.md before meaningful implementation work.
  • Read .ai/generated/context.md when the task needs broader project state, active constraints, or recent cross-cutting changes.
  • If .ai/generated/context.md is missing or empty, generate it from scratch using .ai/prompts/generate_context.md before meaningful implementation work.
  • Keep generated files compact and only open relevant files under .ai/memory/* when deeper detail is needed.
  • Use .ai/memory/* as the source of truth for decisions, changes, requirements, and issues.
  • Update project memory after meaningful work.
  • Regenerate index/context from memory when either file is missing, empty, or stale.
  • Do not store secrets in Threadbase files.

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.
