CrossPad development toolkit: the crosspad-mcp server plus three Claude Code skills — crosspad (onboarding/help: ecosystem map, install & config, per-role guides, tool cheat-sheet, FAQ — use this first), swd-tracer (real-time SWD variable tracing for CrossPad r20 / STM32G0B

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

Rescanned at commit a0e3bbe992d1.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    eval/grade.test.ts, line 153 fs.rmSync(file, { force: true });

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    eval/hil-triage-live.mjs, line 28 const res = await fetch(TYPESAFE_ENDPOINT, {

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    docs/superpowers/plans/2026-08-25-crosspad-hil-p0-core.md, line 1 # crosspad-hil P0 core Implementation Plan

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
