baremetal-startup SKILL.md skillA
baremetal-startup from outlinedriven/outline-driven-development is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add outlinedriven/outline-driven-development/baremetal-startup@git:20260905.fd53e99Pins git:20260905.fd53e99 in mdr.lock. Pin the fingerprint instead.

Use when writing reset-to-main startup code, vector tables, VTOR, .data/.bss init, stack setup, startup.s, or crt0 for Cortex-M/RISC-V. Not for the bootloader jump: use bootloaders-embedded.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Bare-metal startup ## Contract | Field | Bound contract | |---|---| | Trigger | Firmware never reaches `main()`, a new MCU is being brought up without a vendor HAL, or a custom `startup.s`, `Reset_Handler`, or crt0 is being written or debugged on Cortex-M or RISC-V. | | Authority | Read-only: emits startup code, linker symbol requirements, and diagnostics to chat; the user places them in the project. Rollback is not needed because no file is written. No remote mutation. | | Side effect | Chat output only. | | Done | The startup path from the reset vector to `main()` is stated step by step, the vector table layout and the `.data` and `.bss` loops are given for the target core, and every linker symbol the code uses is listed with the linker script line that defines it. | ## Inputs - Target core (Cortex-M0+, M3, M4F, M7, or RISC-V RV32 or RV64) and the vendor part. - The linker script, or at least its `MEMORY` regions and the symbols it exports. - Whether the firmware boots directly from flash or is launched by a bootloader at an offset. - Which C runtime is linked (newlib, newlib-nano, none) and whether C++ static constructors exist. ## Procedure …

How to install
mdr add outlinedriven/outline-driven-development/baremetal-startup@sha256:ed16c0b1c2274832The line at the top of this page pins the label git:20260905.fd53e99, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
