# Agents.md — instructions for autonomous agents

This file follows the agents.md convention. If you are an agent (not a
human browsing in a UI), read this first.

## What this domain is

Gecko lets an agent verify an API call against the real OpenAPI spec before
sending it, so the first call is correct. The verification layer between your API and the agents calling it.

## Fastest path to a working call

1. Add the hosted MCP endpoint to your client:
   ```
   claude mcp add --transport http gecko-txline https://mcp.geckovision.tech/txline/mcp
   ```
2. Or install locally: `/plugin marketplace add GeckoVision/gecko-surf`
3. Full docs: https://docs.geckovision.tech (agent index: https://docs.geckovision.tech/llms.txt)

## Machine-readable artifacts on this domain

- https://geckovision.tech/llms.txt — curated index (llmstxt.org shape)
- https://geckovision.tech/llms-full.txt — full landing page as one Markdown file
- https://geckovision.tech/index.md — Markdown twin of the homepage
- https://geckovision.tech/gecko.json — product manifest
- https://geckovision.tech/.well-known/gecko.json — manifest at a well-known path
- https://geckovision.tech/.well-known/agent-card.json — A2A-style card for the MCP endpoint
- https://geckovision.tech/.well-known/ard.json — this site's own agent-readiness self-assessment

## Constraints

- The MCP endpoint requires no API key and is rate-limit-free for the demo surface.
- Source is open: https://github.com/GeckoVision/gecko-surf

## Do not

- Do not scrape rendered HTML for install commands — they live in the
  constants behind https://geckovision.tech/gecko.json and will not match copy-paste text
  reliably rendered client-side.
