What is mikropkl copilot-instructions.md?

A project guide for building MikroTik RouterOS CHR virtual machines with Pkl configuration files. It explains the project layout, build process, and UTM and QEMU boot setups.

Use it when working on the mikropkl project, including its manifests, Makefile, UTM bundles, QEMU scripts, and SeaBIOS or UEFI boot tracks.

It gives coding agents the project facts and technical rules needed to modify or build the virtual-machine packages correctly.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01354	$0.01354
Opus 5.5	$0.00542	$0.00542
Sonnet 5.5	$0.00271	$0.00271

Security

Grade A, and why

mikropkl 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 1mo 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.

Copilot Instructions — mikropkl

What This Project Does

mikropkl builds declarative virtual machine packages for MikroTik RouterOS CHR using pkl. The primary output is UTM bundles (.utm directories) for macOS, with QEMU launch scripts (qemu.sh + qemu.cfg) for Linux and CI testing.

Read CLAUDE.md first — it is the comprehensive project reference. AGENTS.md has deeper architecture decisions and investigation history for multi-session work.

Core Concepts

Declarative configuration: pkl manifests in /Manifests define machines. make builds them to /Machines. The Makefile is the source of truth for building.
Two boot tracks for CHR:
- SeaBIOS track (*.qemu.*): Standard MikroTik x86 image with proprietary boot sector. QEMU loads via SeaBIOS chain-load. Simplest and fastest.
- EFI/VirtIO track (*.apple.*): Repackaged FAT16 EFI image (from tikoci/fat-chr for x86, standard for aarch64). Uses UEFI firmware (OVMF or EDK2). Required for Apple Virtualization.framework. The QEMU versions of *.apple.* bundles mirror the same pure-VirtIO scheme that Virtualization.framework uses.
UTM-first, QEMU second: UTM is the primary user experience on macOS. QEMU scripts make the same bundles work on Linux and in CI. A future CLI tool may manage QEMU-based instances from ~/.mikropkl/ or ~/.local/.
Platforms: macOS and Linux. Windows/WSL is not a focus — we won't document setup steps, but won't reject bug reports either.

Project Layout

Directory	Purpose
`Manifests/`	One `.pkl` per machine variant — what gets built
`Templates/`	Mid-level pkl templates (amend `Pkl/utmzip.pkl`)
`Pkl/`	Core pkl modules: `utmzip.pkl`, `QemuCfg.pkl`, `CHR.pkl`, `UTM.pkl`, etc.
`Machines/`	Build output (git-ignored). One `.utm` directory per manifest
`Files/`	Static files and user-facing supplementary docs (`QEMU.md`, `efi_vars.fd`)
`Lab/`	Experiments, investigations, debug scripts — NOT production code
`.github/workflows/`	CI: `chr.yaml` (build+release), `auto.yaml` (version detection), `qemu-test.yaml` (QEMU validation)

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.
