First Glance

Eye-tracking shows the first three to five seconds decide whether a reader connects to a thing at all. The gaze lands somewhere before conscious thought. If what it lands on repels, no amount of body text wins the reader back.

This skill runs that gate on the surfaces developers actually look at.

The model

Two questions, in this order:

1. Where does the eye land first?
2. Is that the right thing — the one piece that tells the reader what this is and whether it is for them?

Then one check: does anything make the reader want to look away?

The procedure

1. Read the artifact for about five seconds, the way a stranger would. Do not study it. First impression only.

2. Report:

   • First fixation. What did the eye hit first? The name, a wall of params, a stack trace, a badge wall, a 12-line signature?
   • Right thing or not. Did the first fixation tell the reader what this is and whether it is theirs? Or did it land on noise?
   • Repulsion. What made you want to look away? Cryptic abbreviation, leaked internals up front, a screen of imports, ten config options before one example.

3. Apply the gate. If the surface repels in the first five seconds, fix the surface before anything else. Do not add more docs to a thing that repels.

Fixes by artifact

• Function signature — lead with the verb and the one argument that matters. Push the rest into an options object.
• Error message — first line says what broke and what to do. Trace below.
• README — first screen says what it is, who it is for, and the one command to start. Everything else scrolls.
• CLI --help — most-used command first. Not alphabetical.
• PR description — first line is the change and why. Not the ticket number.

When not to use it

Private code only you touch. The cost of a bad surface scales with the audience. Do not polish a helper no one else will ever call.
