# Steps
## Step 1
Run this command:
```bash
omni-dev git commit message view $ARGUMENTS
```
## Step 2
Analyse the result. The result of the previous command is self describing.
## Step 3
Craft new commit messages for each commit and overwrite them to `.ai/scratch/amendments-<random-hash>.yaml`.
Where `<random-hash>` is a random hexadecimal hash of length 8.
Assume the `.ai/scratch` direcotry exists and try creating the directory if writing the file fails.
The file must conform to the following schema (validation required)
```yaml
amendments: # required, non-empty array
- commit: "<40-hex-sha>" # required, exactly 40 lowercase hex
message: | # required; Conventional Commit
<subject line>
<wrapped body at 72 cols>
<optional footers>
```
## Step 4
Run this command:
```bash
omni-dev git commit message amend .ai/scratch/amendments-<random-hash>.yaml
```
# Troubleshooting
If the `omni-dev` tool is not installed, then install this: https://crates.io/crates/omni-dev (at least `v0.3.0`).
