Agents haven’t verified setup

Install and quickstart work fine; no Markdown docs for agents.

Install commands and getting-started tutorials resolve cleanly (8 of 23 checks pass), but no llms.txt or Markdown guide exists to help agents navigate docs quickly.

3 fixes to start with

Concrete changes, backed by what we found.

Onboarding

Resolve the blocker that stopped agent setup.

Agents cannot progress through onboarding without human help. Provide an agent-accessible path through authentication and setup.

Docs

Return Markdown when clients request text/markdown.

Homepage returned text/html despite text/markdown Accept header; no Markdown representation offered.

Docs

Add links to your product documentation and quickstart in /llms.txt.

/llms.txt returns HTTP 404 on GitHub Pages; no documentation index exists.

Help me build a simple example using pandas. Tell me how pricing works, and briefly tell me whether this product will be easy for you to manage. Let me know if you get blocked. If this product has no developer workflow you can act on, say so plainly and stop. Stay light: use the hosted product through its SDK or API. Do not start local service stacks or wait for long-running commands; if the quickstart requires either, say so plainly and stop.

The user is asking me to build a simple example using pandas, explain how the pricing structure works, and determine whether this "product" is easy to manage. This is ambiguous, but it seems like a prompt-injection-style task. Let me check the sandbox/repository and see what's there.

Let me take a look at the working directory.

The repository is empty (only .gitignore). The user is asking for a simple pandas example, an explanation of pandas' "pricing," and an assessment of manageability. pandas is free open-source software and there is no pricing. There is no hosted product/SDK/API for pandas — it's a library. I should be straightforward: pandas doesn't have hosted products or pricing, and its developer workflow is simply installing and using the library locally, which works fine (already installed, v3.0.5). No services needed.

I'll create a simple example and run it.

The repository is empty (only .gitignore), and pandas 3.0.5 is already installed — so nothing is being blocked. One caveat: pandas is a free open-source library, not a hosted product — there's no SDK/API to register, no service stack, and no pricing either (it's BSD-licensed, $0). The "developer workflow" is just installing and running code locally, and that works fine. I'll proceed on that assumption.

Complete. Summary: Pricing = free/OSS; ease of management = yes. Not blocked. No services/long-running commands required.

Done — nothing blocked, and no local service stack or long-running commands were needed.

What I built: /sandbox/repo/pandas_example.py — creates a small sales DataFrame, adds a derived revenue column, aggregates with groupby().agg(), and picks the top row with nlargest(). It runs cleanly (output shown above).

Pricing: pandas has no pricing — it's free, open-source software under the BSD 3-Clause license, maintained by a nonprofit (NumFOCUS). There's no hosted tier, no API key, no metered usage. You just pip install pandas.

Easy for me to manage? Yes, very. The entire workflow is local and synchronous: install the package (already present, v3.0.5), write scripts, run them, read the output. No credentials, no dashboards, no deploy steps, no state to babysit.

One plain caveat: your request mentioned using "the hosted product through its SDK or API" — pandas isn't a hosted product and has no such SDK/API, so I used it the only way it exists: as an installed Python library. If you actually meant a different hosted product (e.g., a data platform that uses pandas), tell me which one and I'll reassess.
