Sample content. This is a placeholder post for the first version of the site.

Why this matters

Reliable tool calling patterns that reduce hallucinations and improve agent reliability. This section is filler text that shows how long-form reading looks on Andraid, with comfortable line length and spacing.

A quick example

const agent = createAgent({ model: 'frontier-model', tools: [search, shell] });
for await (const step of agent.run('Fix the failing test')) {
  console.log(step.type, step.summary);
}

Comparison

Model	Context	Tool use	Price / 1M tokens
Model A	200K	Excellent	$3.00
Model B	1M	Good	$1.25
Open-weight C	128K	Fair	Self-hosted

Takeaways

• Measure on your own tasks, not just leaderboards.
• Use prompt caching and small models where possible.
• Keep the harness simple until it hurts.
