bus-debugging
Skill28 starsChanged 28 days agoMITView on GitHub
Diagnose SPI, UART, CAN and I2C protocol failures using transaction evidence and electrical constraints. Use when requests involve corrupt bytes, wrong SPI mode, framing, bus-off, chip-select timing or DMA transfers; use I2C bring-up for basic discovery.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
3 rules. About 0 are common, 3 are distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈3
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 9
Read the shared embedded contract and keep source/build, device and physical evidence separate.
- Distinctive: line 12
Read protocol branches. Identify exact controller, peripheral, voltage domain, pins/mux, clock, transfer mode, payload and capture point.
- Distinctive: line 15
Do not assume a decoded analyzer trace proves voltage margin or signal quality.
≈ “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.

Bus Debugging
Read the shared embedded contract and keep source/build, device and physical evidence separate.
Read protocol branches. Identify exact controller, peripheral, voltage domain, pins/mux, clock, transfer mode, payload and capture point. Separate electrical, framing, driver and application interpretation. Do not assume a decoded analyzer trace proves voltage margin or signal quality.
Choose a minimal transaction with a datasheet-defined response. Compare the
actual wire capture with the requested byte order, edges, framing and timeout.
For I2C discovery/pull-ups route to i2c-bringup-diagnostician; use this skill
for transaction framing and cross-layer diagnosis. Scans/transfers can write
or trigger devices, so keep attached actuators in the required safe state.
For DMA inspect buffer lifetime, alignment/cache coherency where applicable, completion/error path and concurrent ownership before adding arbitrary delays. Compare a bounded polling transfer to DMA only when the test is appropriate and authorized. Keep the failing configuration and change one causal variable.
Deliver annotated expected/observed transaction, evidence location and next check. Distinguish MCU peripheral errors, analyzer decoding assumptions and what remains electrically unmeasured.
See platform coverage for the exact tested combination. A source procedure is not a claim that every target was tested.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
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.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
