oraclebone: Instructions file for GitHub Copilot

.github/copilot-instructions.md

oraclebone copilot-instructions.md is an instructions file for GitHub Copilot from sapuyou45-bit/oraclebone. It costs 503 tokens per session, scanned A, original, MIT.

Repository instructions for oraclebone, a Python command-line tool that produces I Ching divination readings. They cover the project layout, skill files, security rules, and how readings must be generated by audited code.

In plain words
What is it for?
Use them when changing oraclebone, its skills, reading scripts, schemas, references, or shared safety policies.
Why use it?
They prevent unsafe shortcuts such as letting an AI model invent results, using hidden network calls, or mishandling randomness and sensitive data.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file. Also seen: mentions AGENTS.md.

This is sapuyou45-bit/oraclebone's own configuration. It tells GitHub Copilot how to work on oraclebone 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 oraclebone 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

oraclebone 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.

Project shape

  • Python package oraclebone exposes the CLI oraclebone.
  • Per-skill skill folders live under skills/<skill>/ and each ships:
    • SKILL.md (trigger description + workflow)
    • agents/openai.yaml, agents/claude.yaml, agents/gemini.yaml, agents/cursor.mdc
    • scripts/ (delegates to the package; standalone fallback when copied as a folder)
    • references/ (sources, interpretation template, cards/hexagrams reference)
  • Shared cross-skill policies live in shared/.
  • JSON output schemas live in schemas/.

Non-negotiable rules when writing code

  1. Never let the model generate the divination result. Every code path that produces a draw / hexagram / position must go through the audited script. Adapters re-export the CLI; they do not call out to a model.
  2. Randomness uses system entropy by default. Seeded mode is reserved for tests and reproducible demos and must be documented as such in any new surface.
  3. No hidden network calls, no shelling out, no telemetry, no secret handling. Per SECURITY.md.
  4. Safety boundaries: refuse medical / legal / financial / emergency / crisis advice. See shared/safety-policy.md.
  5. JSON outputs need a matching schema in schemas/ and a unit test.
  6. Python 3.9–3.12 compatibility (use from __future__ import annotations for new modules).

Workflow expectations

  • Tests must pass: python3 -m unittest discover -s tests (49 tests today, all four CI matrix versions).
  • New behaviour must come with tests under tests/.
  • Update CHANGELOG.md [Unreleased] for every user-facing change.
  • Update RELEASE_NOTES.md once during the release-cutting PR.
  • PRs use the checklist in .github/PULL_REQUEST_TEMPLATE.md.

Releasing

Maintainer-only. See docs/maintainer/release-and-pypi.md. Tag vX.Y.Z → release workflow attaches sdist+wheel, and publishes to PyPI when PYPI_API_TOKEN secret is set.

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.
