Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00310 | $0.00310 |
| Opus 5 | $0.00155 | $0.00155 |
| Sonnet 5 | $0.00062 | $0.00062 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
adrkit 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 2d 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
adrkit — GitHub Copilot
Project memory for this repository is host-neutral and lives in one file.
Read AGENTS.md before doing anything else. It carries the
project overview, the distribution surfaces and their current evidence-ladder
status, the Bun toolchain rules, and the agent working-directory rules —
including the two that have been violated in practice, about never writing to
the maintainer's main checkout and never deleting a branch on commit ancestry
alone.
Nothing project-specific is duplicated here on purpose. A second copy costs context on every session and drifts from the first.
GitHub Copilot specifics
- Path-scoped rules live in
.github/instructions/and apply automatically to the globs they declare —use-bun.instructions.mdis the one that matters most here. .github/agents/and.github/prompts/hold the Spec Kit agent and prompt files. They are generated by Spec Kit; edit the source under.specify/rather than these copies.- This repository is also its own plugin marketplace:
copilot plugin marketplace add mbeacom/adrkit, thencopilot plugin install adrkit@adrkit. When developing that plugin, note thatcopilot plugin installreports only a skill count — "Installed 1 skill" does not mean the agent and commands were dropped. Verify in a fresh session.
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.
