Why use it?
They give the coding agent the project’s data boundaries, required documents, routing rules, and verification expectations.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is williamisnotdefined/rubiks-cube-solver's own configuration. It tells GitHub Copilot how to work on rubiks-cube-solver 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 rubiks-cube-solver 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

rubiks-cube-solver wca-data-boundary.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.

WCA Data Boundary

Use for the WCA Data workspace, OpenAPI contract, import worker, PostgreSQL lifecycle, or web WCA client.

Read First

  • ai/rules/wca-data-rules.md
  • ai/rules/frontend-rules.md
  • ai/rules/testing-rules.md
  • ai/architecture/wca-data.md

Workflow

  • Identify whether the change owns public API, canonical data, import, persistence, worker, or web consumption.
  • Preserve contract-first OpenAPI and dataset metadata; keep Axum/Nginx routing aligned around the non-localized 308 docs redirect.
  • Use fixture/disposable verification unless a real target was explicitly approved.
  • Run WCA build/tests and the relevant web client tests; run public smoke only against an intentional available target.

Referenced Context

Reference: ai/rules/wca-data-rules.md

WCA Data Rules

  • Treat apps/wca-data/openapi/wca-data-v1.yaml and contract tests as the public API contract.
  • Keep import, canonical domain, public API, persistence, and worker concerns separately owned.
  • Validate archive size and expected entries; extract only expected TSV files.
  • Run local write checks with npm run wca:sync-once -- --fixture. Real sync and persistent migrations require explicit target approval.
  • Never execute downloaded SQL or expose fixture data in production. A successful production import retains only the active dataset; retired and failed datasets are removed after atomic publication, so rollback requires a backup or fresh verified import.
  • Verify workspace changes with npm run wca:build and npm run wca:test; use the public smoke command only when the target is intentional and available.

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.
