## Work

- [Howff](https://nikola.fyi/work/howff.md): Grok Bots you can read before you run. Live at https://howff.dev
- [Reminded](https://nikola.fyi/work/reminded.md): Expiry reminders that fire against the action-by date, not the printed expiry. Live at https://getreminded.app
- [MockIdP](https://nikola.fyi/work/mockidp.md): A throwaway SAML identity provider that actually signs assertions. Live at https://mockidp.dev

## Writing

- [Read the prompt first](https://nikola.fyi/writing/read-the-prompt-first.md): Why Howff stores Grok Bots as git files you can actually read.
- [The date that matters is not the expiry date](https://nikola.fyi/writing/the-date-that-matters.md): Why Reminded is built around notice periods.
- [A mock IdP that actually signs](https://nikola.fyi/writing/a-mock-idp-that-signs.md): Most SAML test tools are toys. This one issues real assertions.
- [On shipping small tools](https://nikola.fyi/writing/shipping-small-tools.md): If I would not still build it when nobody is watching, it does not ship.

## Optional

- [About](https://nikola.fyi/about.md): Tools, quiet software.
