Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is am-space/own-planner's own configuration. It tells GitHub Copilot how to work on own-planner 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 own-planner 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

own-planner frontend.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

Frontend Instructions

Technology

  • Use TypeScript and React for client-side changes.
  • Match the existing React component, context, and routing patterns.
  • The client uses Vite, React Router, and MUI; prefer existing dependencies already in the project.
  • Keep API types aligned with backend contracts.

Coding rules

  • Prefer extending existing hooks, contexts, services, and shared types over introducing new patterns.
  • Do not introduce state-management libraries unless explicitly requested.
  • Keep components focused and avoid broad refactors unless required by the task.
  • Match the existing styling and component composition style used in the edited area.

Change preferences

  • Keep changes minimal and scoped to the requested task.
  • Avoid breaking UI behavior or API contracts unless explicitly requested.
  • When editing existing files, match their formatting and local conventions.
Changes

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.
