Agent Skills: markdown

markdown

• Write like you're explaining to a competent peer, not selling to a novice (no handholding).
  • State facts directly and cut everything that doesn't add information.
  • Assume the reader is smart enough to infer context and figure things out.
• Use ATX-style headings (i.e., # Heading 1, ## Heading 2, etc.) instead of Setext-style (Heading 1\n=========).
• Use markdownlint to lint markdown files.
  • markdownlint --disable MD013 -- <somefile.md>
  • if not installed, install with npm install -g markdownlint-cli
  • markdownlint --disable MD013 --fix <somefile.md> to auto-fix issues.
• Nest supplementary details.
  • When a list item has supplementary information that extends the line or interrupts the main point, move it to a nested list item.
  • Main point stays short and scannable.
    • Supporting details, examples, clarifications, conditions, or caveats go here.
    • Lines never grow too long.
• Use only characters present on the US international keyboard.
  • e.g.: ñ, é, ->, =>, >=, etc. are all fine.
  • Fancy quotes, dashes, etc. are not.
• When writing text, use semantic linebreaks, after full stops.
  • Avoid hard-wrapping paragraphs at a fixed column-width.
  • It's painful to maintain; deleting one word forces every following line to shift.

numbered lists should be contiguous

• Do not attempt to continue numbered lists across titles; examples below.

### title 1

1. thing
2. thing

### title 2
<!-- this does not work; it should start on 1 again -->
3. other thing
4. other thing

represent folder hierarchies with bulletpoints

Avoid using code blocks with tree structures; they're hard to edit and maintain.

project/
├── src/
│   ├── task.py
│   └── config.py
└── pyproject.toml

Prefer bulletpoint lists; they're more easily editable by humans.

• project/
  • src/
    • task.py
    • config.py
  • pyproject.toml

represent tables with bulletpoints

Whenever one of the columns of a table is a key/indexing field, this works well.

| id | mission | market cap | |---|---|---| | apple | to create technology that empowers people and enriches their lives. | $3.93T | | meta | to build the future of human connection and the technology that makes it possible. | $1.72T |

They're easier to edit and less horizontally long.

• apple

  • to create technology that empowers people and enriches their lives.
  • $3.93T

• meta

  • to build the future of human connection and the technology that makes it possible.
  • $1.72T

• Always prefer to omit the column names as it'd lead to a lot of repetition.

• The above is a naive example of direct conversion.

• Design-wise, it could look better if:

  • columns with consistently shorter values came first.
  • columns with fixed short length to be inlined along with the "id" or some other short field
    • e.g.: "meta ($1.72T)"
