+# Beads - AI-Native Issue Tracking
+
+Welcome to Beads! This repository uses **Beads** for issue tracking - a modern, AI-native tool designed to live directly in your codebase alongside your code.
+
+## What is Beads?
+
+Beads is issue tracking that lives in your repo, making it perfect for AI coding agents and developers who want their issues close to their code. No web UI required - everything works through the CLI and integrates seamlessly with git.
+
+**Learn more:** [github.com/steveyegge/beads](https://github.com/steveyegge/beads)
+
+## Quick Start
+
+### Essential Commands
+
+```bash
+# Create new issues
+bd create "Add user authentication"
+
+# View all issues
+bd list
+
+# View issue details
+bd show <issue-id>
+
+# Update issue status
+bd update <issue-id> --status in_progress
+bd update <issue-id> --status done
+
+# Sync with git remote
+bd sync
+```
+
+### Working with Issues
+
+Issues in Beads are:
+- **Git-native**: Stored in `.beads/issues.jsonl` and synced like code
+- **AI-friendly**: CLI-first design works perfectly with AI coding agents
+- **Branch-aware**: Issues can follow your branch workflow
+- **Always in sync**: Auto-syncs with your commits
+
+## Why Beads?
+
+✨ **AI-Native Design**
+- Built specifically for AI-assisted development workflows
+- CLI-first interface works seamlessly with AI coding agents
+- No context switching to web UIs
+
+🚀 **Developer Focused**
+- Issues live in your repo, right next to your code
+- Works offline, syncs when you push
+- Fast, lightweight, and stays out of your way
+
+🔧 **Git Integration**
+- Automatic sync with git commits
+- Branch-aware issue tracking
+- Intelligent JSONL merge resolution

+# Beads Configuration File
+# This file configures default behavior for all bd commands in this repository
+# All settings can also be set via environment variables (BD_* prefix)
+# or overridden with command-line flags
+
+# Issue prefix for this repository (used by bd init)
+# If not set, bd init will auto-detect from directory name
+# Example: issue-prefix: "myproject" creates issues like "myproject-1", "myproject-2", etc.
+# issue-prefix: ""
+
+# Use no-db mode: load from JSONL, no SQLite, write back after each command
+# When true, bd will use .beads/issues.jsonl as the source of truth
+# instead of SQLite database
+# no-db: false
+
+# Disable daemon for RPC communication (forces direct database access)
+# no-daemon: false
+
+# Disable auto-flush of database to JSONL after mutations
+# no-auto-flush: false
+
+# Disable auto-import from JSONL when it's newer than database
+# no-auto-import: false
+
+# Enable JSON output by default
+# json: false
+
+# Default actor for audit trails (overridden by BD_ACTOR or --actor)
+# actor: ""
+
+# Path to database (overridden by BEADS_DB or --db)
+# db: ""
+
+# Auto-start daemon if not running (can also use BEADS_AUTO_START_DAEMON)
+# auto-start-daemon: true
+
+# Debounce interval for auto-flush (can also use BEADS_FLUSH_DEBOUNCE)
+# flush-debounce: "5s"
+
+# Git branch for beads commits (bd sync will commit to this branch)
+# IMPORTANT: Set this for team projects so all clones use the same sync branch.
+# This setting persists across clones (unlike database config which is gitignored).
+# Can also use BEADS_SYNC_BRANCH env var for local override.
+# If not set, bd sync will require you to run 'bd config set sync.branch <branch>'.
+# sync-branch: "beads-sync"
+
+# Multi-repo configuration (experimental - bd-307)
+# Allows hydrating from multiple repositories and routing writes to the correct JSONL
+# repos:
+#   primary: "."  # Primary repo (where this database lives)
+#   additional:   # Additional repos to hydrate from (read-only)
+#     - ~/beads-planning  # Personal planning repo
+#     - ~/work-planning   # Work planning repo
+
+# Integration settings (access with 'bd config get/set')
+# These are stored in the database, not in this file:
+# - jira.url
+# - jira.project
+# - linear.url
+# - linear.api-key
+# - github.org
+# - github.repo

+name: test-writer
+description: Writes tests following Elixir/Phoenix best practices. Ensures DRY tests with proper helper functions, no duplicated setup code, and correct parameter defaults. Use when writing or modifying tests.
+---
+
+# Test Writer Skill
+
+## Overview
+
+This skill provides guidelines for writing clean, maintainable Elixir/Phoenix tests following best practices. It focuses mainly on integration tests. For unit tests, we also want glanceable tests with unique names for values, test helpers, custom matchers and shared setups where appropriate.
+
+## Core Principles
+
+### 1. DRY Tests
+
+Avoid duplication by creating focused helper functions:
+
+**Bad:**
+```elixir
+test "GET /users returns index", %{conn: conn} do
+  conn = get(conn, "/users")
+  body = html_response(conn, 200)
+  assert body =~ "Users"
+end
+
+test "GET /users/:id returns show", %{conn: conn} do
+  conn = get(conn, "/users/1")
+  body = html_response(conn, 200)
+  assert body =~ "User"
+end
+```
+
+**Good:**
+```elixir
+defp goto_users_page(conn, suffix \\ ""), do: get(conn, "/users" <> suffix)
+
+test "GET /users returns index", %{conn: conn} do
+  conn = goto_users_page(conn)
+  assert html_response(conn, 200) =~ "Users"
+end
+
+test "GET /users/:id returns show", %{conn: conn} do
+  conn = goto_users_page(conn, "/1")
+  assert html_response(conn, 200) =~ "User"
+end
+```
+
+
+### 2. Separate Helpers for Different Assertion Patterns
+
+Don't use conditionals in helpers to handle different cases:
+
+**Bad:**
+```elixir
+defp goto_users_page(conn, suffix \\ "", check_title \\ true) do
+  path = "/users" <> suffix
+  conn = get(conn, path)
+  body = html_response(conn, 200)
+  if check_title, do: assert body =~ "Users"
+  assert body =~ "AppLayout"
+  body
+end
+```
+
+**Good:**
+```elixir
+defp goto_users_page(conn, suffix \\ "") do
+  path = "/users" <> suffix
+  conn = get(conn, path)
+  body = html_response(conn, 200)
+  assert body =~ "Users"
+  assert body =~ "AppLayout"
+  body
+end
+
+defp goto_user_page(conn, suffix) do
+  path = "/users" <> suffix
+  conn = get(conn, path)
+  body = html_response(conn, 200)
+  assert body =~ "AppLayout"
+  body
+end
+```
+
+## Test Structure
+
+### Context Block
+
+```elixir
+describe "resource name" do
+  # Shared setup in context if needed
+  # test "scenario" do ...
+end
+```
+
+### Value Aliasing
+
+Never reuse value names. Elixir is immutable, but value aliasing is confusing. Use unique, meaningful names for the left hand side of assignments. Or use pipes `|>` to eliminate the need for naming.
+
+```elixir
+test "GET /users returns index", %{conn: conn} do
+  # don't reassign
+  response = get(conn, "/users")
+  # ...
+end
+```
+
+## Common Patterns
+
+### HTML Pages with Layout
+
+```elixir
+defp goto_resource_page(conn, suffix \\ ""), do: ...
+# Asserts common layout elements and page-specific content
+```
+
+### API Endpoints
+
+```elixir
+test "GET /api/resource returns JSON", %{conn: conn} do
+  conn = conn |> put_req_header("accept", "application/json")
+  conn = get(conn, "/api/resource")
+  response = json_response(conn, 200)
+  # Assert structure
+end
+```
+
+### Error Handling
+
+```elixir
+test "returns 404 for nonexistent", %{conn: conn} do
+  assert html_response(get(conn, "/nonexistent"), 404)
+end
+```
+
+## Running Tests
+
+### One focused test file
+
+```bash
+cd /path/to/app
+mix test test/path/to_test.exs
+```
+
+### all tests
+```bash
+make test
+```

+- **Always** handle authentication flow at the router level with proper redirects
+- **Always** be mindful of where to place routes. `phx.gen.auth` creates multiple router plugs:
+  - A plug `:fetch_current_scope_for_user` that is included in the default browser pipeline
+  - A plug `:require_authenticated_user` that redirects to the log in page when the user is not authenticated
+  - In both cases, a `@current_scope` is assigned to the Plug connection
+  - A plug `redirect_if_user_is_authenticated` that redirects to a default path in case the user is authenticated - useful for a registration page that should only be shown to unauthenticated users
+- **Always let the user know in which router scopes and pipeline you are placing the route, AND SAY WHY**
+- `phx.gen.auth` assigns the `current_scope` assign - it **does not assign a `current_user` assign**
+- Always pass the assign `current_scope` to context modules as first argument. When performing queries, use `current_scope.user` to filter the query results
+- To derive/access `current_user` in templates, **always use the `@current_scope.user`**, never use **`@current_user`** in templates

And also, currently, how do I generate just enough and focus on interesting feedback loops instead of code?

+I wrote this last may as well [shallow research tool](https://www.qwan.eu/2025/05/01/agentic-search.html):
 
-- **Layout inheritance is a design decision.** The blog engine rendered pages outside Phoenix's layout pipeline. Getting navbar and CSS onto blog pages meant rethinking how the pieces fit together — not just adding a wrapper div.
+> I want to both get better at using LLMs for programming, and also understand how they work. Marc suggested earlier this year that I write a series of blog posts about my use of them, but I have been drinking from a firehose, and it is quite difficult to figure out a good place to start writing.
-- **Warm aesthetics take intention.** The default Phoenix boilerplate is fine, but it says nothing about who you are. Choosing fonts and colours forced me to think about what "personal but professional" looks like.
+
-- **It's fast when it works, and confusing when it doesn't.** When the agent understands your stack, you move at extraordinary speed. When it doesn't (say, the difference between `@inner_block` and `@inner_content` in Phoenix layouts), you can burn time on a misunderstanding that a human would catch in seconds.
+I have made good progress in learning, and at the same time, practices are still evolving. I see people write patterns. I think it is useful, but too early for that. I am at heuristics (rules of thumb).
+
+That is also why I open sourced the code for this blog [firehose repository on our gitea](https://gitea.apps.sustainabledelivery.com/mostalive/firehose). I think Jekyll, the static site generator we have for QWAN is passable, but I want the option to have a more interactive blog, and since this is going to be a firehose of ideas, give readers the option to subscribe to only what they are interested in, filter posts, like etc. I helped a friend with 'Ghost', but it felt clunky. I like writing in plain text and publishing with `git push` - that works with Jekyll and other static site generators.
+
+I am exploring working in small slices. That does require some initial investment in modularity. If you look at the code, you will notice that some of the blogging functionality is separate from the main site. I want an 'engineering blog' and 'release notes' as a plugin for Software as a Service applications. 
 
 This is the space I want to write in. Shorter than a conference talk, longer than a LinkedIn post. Honest about what works and what doesn't.

+---
+
+I made a skill for a coding agent to help me get more of my draft blog posts over the line. I enjoy writing, and am somewhat fluent in it. Publishing that writing is more hit and miss, however. I often lose energy just before a piece is finished enough. I want to publish more often, and need to form a more effective habit for it.
+
+# What did I get out if it?
+
+I got a working agent 'skill' in an hour or so. I like the QWEN models for their no-bullshit approach to feedback. As it turns out, I have about 60 pages with the 'Candidate Blogpost' tag in my notes, but most of them are not more than an idea. Only some of them have enough detail to turn into a post. I am going to keep this around, prune my candidate blogposts, and add my recent clippings to the mix. 
+
+Quite a few of my candidates were 'just links' according to the model, but as I am inspired by [Simon Willison](https://www.simonwillison.net), there is value in sharing links with a brief description on why I think they are relevant. Probably in a different category.
+
+# How did I develop the skill? 
+
+I was inspired by two writings:
+
+- Jurgen De Smet asking [how do you write long form articles?](https://www.linkedin.com/posts/jurgendesmet_this-is-how-i-write-long-form-articles-these-share-7441394036222935040-JHmv). 
+- Chris Parsons suggested to [brief an agent for daily tasks](https://www.chrismdp.com/stop-prompting-start-briefing/), and use the _backbriefing_ loop from "The Art of Action" to improve them.
+
+I like "The Art of Action" - detailed, yet practical. So I had a chat with a frontier model to develop a skill for a local model to surface notes that are almost finished, with some suggestions to get them over the line.
+
+This was my initial prompt. Full chat transcript in the Further Reading section.
+
+#+begin_quote
+https://www.chrismdp.com/stop-prompting-start-briefing/ suggests an art of action style backbriefing loop for daily work. I would like to use a local model with pi, the shitty coding agent, instead of claude code. I have trouble publishing blogposts. I have many drafts, marked as CandidateBlogPost in an org-roam directory. I wonder if I could make some kind of pi extension or skill that finds candidate blogposts, helps identify ones that are almost finished, with a suggesion on what to do next for the top 3 almost finished, and suggestions for others on what to add. Probably prioritize recency. I could run that as a cron job in the morning, and create a new daily entry (I use daily entries for org-roam) to get me starte.d Goal would be not to have AI write my posts, but help me finish in pomodori instead of days.
+#+end_quote
+
+What I found interesting was that, maybe because I mentioned the links were in an sqlite database, claude desktop spontaneously suggested to create a bash script as part of the skill. I used to have a meta-skill to separate the deterministic parts of agent skills into scripts, but that does not seem to be necessary anymore. I prune my agent setups continuously, only keeping what is needed.
+
+# Tradeoffs
+
+Initially I planned to run this as a scheduled job, but from the development chat it emerged that backbriefing (improving the skill as we run it daily) would not work if it runs scheduled. 
+
+I chose a local coding agent with a local model, because I don't want to share my personal notes with a cloud service, and I thought that a smaller model would be more than powerful enough.
+
+
+## Further reading 
+
+https://claude.ai/share/be0184d9-f2bf-41ba-b2e3-235fe9daf9fd - initial chat do develop the skill
+
+I will share a repository with the skill later. I think it is more instructive to have a look at the prompt, and make one for your own notes, starting from your own goals.

+}
+---
+
+Posts in Firehose are markdown files with a date in the filename. Until now, every published post was immediately visible. That changes today: posts with a future date are now hidden from public views until their date arrives.
+
+This was built in a single session using an agentic dev team -- 12 issues tracked in beads, executed in three parallel phases, producing 232 tests across the blogex library and Phoenix app.
+
+## What changed
+
+### Future-dated posts are hidden from public views
+
+The blog index, tag pages, RSS feeds, and Atom feeds now filter out posts where the date is after today. If you schedule a post for next Tuesday, readers won't see it until then.
+
+![Blog index showing only past-dated posts](/images/scheduled-publishing/scheduled-blog-index.png)
+
+But here's the key design choice: **direct URL access still works**. If you know the slug, you can view the post. This lets authors share preview links with reviewers before the publish date.
+
+![Future post accessible by direct URL](/images/scheduled-publishing/scheduled-direct-access.png)
+
+### Status banners for authors
+
+When you're logged in, draft and scheduled posts show a status banner so you always know what state a post is in. Unauthenticated visitors see nothing -- no clue the post isn't "live" yet.
+
+**Scheduled posts** show a blue banner with the target date:
+
+![Scheduled banner showing target publish date](/images/scheduled-publishing/scheduled-banner-future.png)
+
+**Draft posts** (unpublished) show an amber banner:
+
+![Draft banner on unpublished post](/images/scheduled-publishing/scheduled-banner-draft.png)
+
+### Editor dashboard
+
+A new LiveView at `/editor/dashboard` gives authors a unified view of all non-live content across every blog. Two tabs: drafts and scheduled posts. Scheduled posts show a "days until live" countdown.
+
+![Dashboard drafts tab](/images/scheduled-publishing/scheduled-dashboard.png)
+
+![Dashboard scheduled tab with countdown](/images/scheduled-publishing/scheduled-dashboard-scheduled.png)
+
+The dashboard requires authentication -- unauthenticated users are redirected to the login page.
+
+### Authentication and registration gating
+
+We added `mix phx.gen.auth` for session-based authentication with magic links and password login. Login and registration pages are accessible by direct URL only -- they're intentionally not linked from the public navigation.
+
+Registration is gated to a single email via the `ALLOWED_REGISTRATION_EMAIL` environment variable. Anyone else gets a polite rejection:
+
+![Registration rejected for non-matching email](/images/scheduled-publishing/scheduled-registration-rejected.png)
+
+When the environment variable isn't set, registration is disabled entirely. A demo user (`demo@example.com`) is seeded in dev for local testing.
+
+## How it was built
+
+The feature was planned as an [Allium specification](https://github.com/your-org/allium) with surfaces, rules, and domain entities, then broken into 12 beads (issues) across three phases:
+
+1. **Scheduled posts** (5 beads): date filtering in blogex, unfiltered direct access, feed/router verification
+2. **Authentication** (3 beads): phx.gen.auth scaffolding, registration gating, dev seed
+3. **Dashboard** (4 beads): post visibility helpers, unfiltered registry access, LiveView dashboard, status banners
+
+All 12 beads were executed with parallel agentic workers in isolated git worktrees, then merged and integrated on main. The demo caught one bug (auth check using `current_user` instead of `current_scope`) which was fixed before this post.
+
+## By the numbers
+
+- **232 tests** passing (89 blogex + 143 Phoenix app)
+- **12 beads** planned, executed, and closed
+- **3 phases** run with parallel workers
+- **0 compiler warnings**
