# DEVLog - August

> Discover what happened in August 2026. Qualified signatures took shape at SignatureAPI, the ChatGPT app went public, ParentSignature for Schools rebuilt its roster, and a tiny virtual dog appeared.

August had 822 commits across 13 repositories. Many of them went into personal tools that I keep private. The rest went into SignatureAPI, the school app and one small public gift.

I wrote this devlog later, from my GitHub history, to fill a gap in the series.

## Qualified signatures take shape

[**SignatureAPI**](/projects/signatureapi/) got 322 commits from me. The biggest piece was qualified electronic signatures. A qualified signature needs a certificate held by a trusted provider, so SignatureAPI cannot create it alone. It has to ask someone else to sign.

To do that, I worked on a protocol we call SWP/1, the Signing Worker Protocol. A signing worker is a small service that receives a document fingerprint and returns a signature. I also worked on an adapter for CSC, the Cloud Signature Consortium standard that many providers use. All of this stayed behind a feature flag, so it was not open to everyone yet.

Other work this month:

*   **Testing with AI agents.** Our MCP server got tools to read emails in test mode. An AI agent can now read test emails and get the signing link from them.
*   **Custom authentication.** You can now create a ceremony with custom authentication right from a recipient's page in the dashboard.
*   **Accessibility.** I fixed gaps in the signing ceremony to meet WCAG 2.1 AA, the common accessibility standard. That means better dialogs, error messages that screen readers announce, and visible focus.
*   **Faster tests.** I rebuilt our end-to-end tests so they run in parallel.

On the website, I documented our ChatGPT app, which is now published, and added Codex to the guide for connecting AI clients. I also wrote a page about the Brazil ICP-Brasil attestation from last month.

## Everyone is a person

**ParentSignature for Schools** got 42 commits. The main change was a rebuild of the roster. Now everyone in it is a person, and being the subject of a form is just a role a person can have.

You can add anyone by hand, and you pick who signs by searching for them. Each form record is now a dashboard of documents, with the roster next to it. Every code branch also gets its own preview site that you can log into, which makes testing easier.

[ParentSignature](https://parentsignature.com): A free tool that lets teachers collect parent signatures on school forms digitally.

## A small dog for big questions

I published a tiny public project called [**Perrito de Mar**](https://github.com/RolandoAndrade/virtual-dog). It is a small virtual dog for emotional support, for those moments when big questions feel heavy. Its description says it best: "Un perro pequeño para preguntas grandes."

## Private tools

The rest of the month went into personal tools I am not ready to share. I also started a private collection of skills for AI coding agents, small instruction files that teach an agent how to do a task well.

[**Privacy Policy Review**](/projects/privacy-policy-review/) got an SEO overhaul, with static marketing pages, FAQs and an llms.txt file for AI search engines.

## What's next

*   **SignatureAPI:** more tools for AI agents and developers.
*   **ParentSignature for Schools:** let AI assistants work with the app.

Thank you for reading. Let's keep building!
