Saves a finding that took real time to reach — a non-obvious behaviour, an integration trap, a workaround and the reason it is needed — as committed markdown, stamped with the commit and the file patterns it describes so that it can be detected as stale later. Searches those notes too. Trigger for "save this", "note that", "remember this", "we worked this out the hard way", "do we have notes on", "what did we find about". Not for project decisions — use /ai-brainstorm, which is where a…

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

# ai-note — save what it cost you to find out

## What it produces

A block in the repository's `DECISIONS.md`. One decision, one `## D-NNN` block, with the sections below. Or, when the finding belongs in the docs, prose handed to ai-write. This skill creates no file of its own.

## Steps

1. The bar is thirty minutes. If it took less than that to work out, it will take less than
   that again, and a note about it is noise that hides the ones that matter.
2. Append one block. Do not rewrite an older block. The heading is the id the git floor counts:

    ```markdown
    ## D-NNN: <what we do, in one line>

    Status: Accepted · Date: YYYY-MM-DD

    ### Context

    What forced the choice. Include `found`, `commit`, the files it describes, and `still_true_when`, so a later reader can tell if it rotted.

    ### Decision

    What we do, specific enough to check in the code.

    ### Consequences

    - What this makes easy
    - What this rules out

    ### Alternatives considered

    - **<Option>:** why not
    ```
3. The Decision is the value. Context is why anybody will believe it.
4. Point at the evidence. The command you ran, its output, the line in the vendor's source.

How to install

The exact contents, by fingerprint
mdr add arcasilesgroup/ai-engineering/ai-note@sha256:ce9bbc7177e4f66c

The line at the top of this page pins the label git:20260926.b0fd9cf, 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.
