Add everyone in an email conversation to a Fastmail Contacts group in one click.

Adds an Add all to group item to the People panel’s ... menu, below Invite all to new event. It takes every address the panel is showing — senders and other recipients both — and adds them to a contact group you pick or create on the spot. People who aren’t in your contacts yet get a card made for them, and someone listed under two addresses is recognised as one person, not two. Requires a Fastmail API token with Contacts access, which it prompts for once.

A calendar date-range picker for Fastmail search inside FMail3.

Custom JS/CSS for FMail3 — the sandboxed macOS wrapper around Fastmail. Adds a calendar icon to the search bar; pick a From/To range and it inserts after: / before: tokens and runs the search (the To date is inclusive).

Untrack a committed file and add it to .gitignore in one click.

Adds an “Ignore & Untrack” action to the Source Control context menu that removes the selected file(s) from the git index and writes an anchored .gitignore entry — the fix for “I committed a file I shouldn’t have.”

Generates a fresh Adjective-Noun-Number name on every request.

Human-readable unique names for projects, containers, branches — anything that needs a label you can say out loud. A Blazor WebAssembly app that runs entirely in the browser plus a cross-platform .NET CLI, both sharing one C# core. Format templates, joining styles, number ranges, and word-length filters are all configurable.

brew install clintcparker/tap/name-on

A personal status dashboard: is this site up, and when did we last confirm it?

A small Tauri app for the sites and endpoints you care about. Each site is checked on its own interval, the dot goes green or red, and the last column tells you how long ago that was confirmed. Not a monitoring service — no alerting, no history, no SLA math. Your list lives in ~/Library/Application Support and survives uninstalls.

brew install clintcparker/tap/site-checker

Community workflows for GitHub's Spec Kit, installed through Spec Kit's own catalog.

A published catalog of add-ons for Spec Kit, the spec-driven-development CLI. First workflow: yolo — the full specify → plan → tasks → implement cycle with the two human review gates removed, for changes whose shape you already trust. Registering the catalog once makes every workflow published here available to specify workflow add.
