A coding task usually begins with:
"Where should I look?"
not
"How should I code?"
Finding relevant files is often harder than writing the fix.

When developers enter a new codebase, they don't start coding.
They explore.
AI agents do the same.
The first few files an agent opens often determine the quality of the entire session.

I'm starting to think "Navigation before generation" is becoming a useful design principle for AI agents.
The best agents don't start by writing code.
They start by understanding where they are.

"Load-bearing context" is a great phrase.
A noisy first file doesn't just waste tokens.
It shapes the agent's mental model.
Everything that follows gets filtered through that initial understanding.
That's why navigation quality matters so much.

The best agents behave more like detectives than programmers.
First they trace imports.
Then they follow relationships.
Only then do they write code.

The danger isn't bad context.
It's unchallenged context.
The first model of the repository often becomes the default reality the agent reasons from.
Later evidence gets compared against it instead of replacing it.

I think you're describing something important:
The first context gets treated as a prior.
Everything that follows is interpreted relative to it.
If the initial model is wrong, agents can spend the rest of the session reconciling reality to a bad.
