Diagnose embedded boot, flash layout, image validation and reset loops with a non-destructive recovery path. Use when requests involve bootloader/application offsets, vector tables, partitions, bad firmware or a device that no longer starts.

We split this skill into the rules it gives an agent

4 rules. About 0 are common, 2 are distinctive, and 2 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈2

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common

  • Very specific
  1. Distinctive:

    Read the shared embedded contract and keep source/build, device and physical evidence separate.

    line 9
  2. Distinctive:

    Read recovery decision path.

    line 12
  3. Very specific:

    Check supply/reset/boot straps and host port/probe ownership separately.

    line 20
  4. Very specific:

    Use probe-debugging for target access, usb-debugging for enumeration and ota-deployment-guardian for update-slot/persistent-schema …

    line 28

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Boot and Flash Recovery

Read the shared embedded contract and keep source/build, device and physical evidence separate.

Read recovery decision path. Preserve original boot/reset logs and identify board/chip, boot chain, image format, flash map, security state and intended firmware before proposing a write. Readout may be restricted; an empty or denied read is not proof the flash is erased.

Inspect available ELF/bin/hex/UF2 metadata offline. Compare partition/linker addresses, vector-table placement, slot limits and image headers against the exact target. File extension and binary length do not establish a load address. Check supply/reset/boot straps and host port/probe ownership separately.

Choose the least destructive recovery supported by that exact board. Protect calibration, provisioning, user files and security keys. Mass erase, unprotect, factory reset, fuse changes and bootloader replacement have distinct effects; never use them as an automatic first repair. A failed upload does not authorize removing protection or bypassing signature/anti-rollback checks.

Use probe-debugging for target access, usb-debugging for enumeration and ota-deployment-guardian for update-slot/persistent-schema compatibility. Deliver the preservation plan, exact artifact/target/address, authorized write steps if any, and separate verification after reset.

See platform coverage for the exact tested combination. A source procedure is not a claim that every target was tested.

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
