Travis Herbranson 956bf8d0c3 web: add-to-queue form on the dashboard (HTMX, parity with CLI add) 
Extracts the `second-brain add` CLI's queueing logic into a service
module (sources_service.add_source) so the CLI and the new web POST
route share the same validation, dedupe, and source_type heuristic —
no behaviour drift between the two entry points.

UI:
- The dashboard body (Pipeline counts + Settings snapshot + Recent
  activity) moves into _dashboard_body.html, wrapped in
  `<div id="dashboard-body">`. HTMX targets that id for swap.
- A new "Add to queue" section sits at the top of the partial: URL
  (required, type=url), Domain (select matching DOMAINS), Title and
  Focus (both optional, match the CLI flags). hx-post=/sources/add,
  hx-target=#dashboard-body, hx-swap=outerHTML — same pattern as the
  settings save form.

Route:
- POST /sources/add calls sources_service.add_source inside a single
  transaction, then re-renders _dashboard_body.html so the pipeline
  counts and recent-activity list update in place. Flash slots above
  the form report:
    ✓ Queued <type>: <url>            on a fresh add
    ✓ Already queued (id=…, status=…) on a dupe (matches CLI text)
    ✗ <validation message>            on bad URL / unknown domain

CLI:
- `second-brain add` now delegates to the same service. Field values
  for the success echo are captured inside the session block so a
  post-commit detached-instance access can't fail. Bad input exits 2
  with a clear stderr message instead of raising.

Live-verified through the web container on herbys-dev: dashboard
renders the form, happy add lands a row, dup-detect matches the CLI
phrasing, two validation errors surface as red flashes, swap target
id survives across swaps, no tracebacks in uvicorn logs.

README.md

second-brain

A personal knowledge system built on a video/article extraction pipeline and an LLM-maintained wiki (inspired by the Karpathy LLM Wiki pattern).

What it does

  1. Pull — download YouTube videos or fetch web articles
  2. Transcribe — extract transcripts via Whisper (videos) or trafilatura (articles)
  3. Extract — single-shot Claude call produces structured notes per source
  4. Review — web UI to accept or reject extractions
  5. Compile — wiki compiler folds accepted extractions into a living Obsidian vault

Quick start

# Install dependencies
uv sync

# Copy and edit config
cp config/settings.toml config/settings.local.toml

# Queue a source
uv run second-brain add https://www.youtube.com/watch?v=...

# Run the pipeline
uv run second-brain process

# Review in the web UI
uv run second-brain serve

# Compile to wiki
uv run second-brain compile

Domains

Extractions are tagged by domain so the right prompt template is used:

Domain Focus
development Software, programming, systems
content Content creation, video production
business Entrepreneurship, marketing, ops
homelab Self-hosted infra, networking, DevOps

Extractor backends

Two backends, selectable via [extractor].backend in config/settings.toml:

  • cli (default) — shells out to claude -p --output-format json --json-schema .... Runs under your Max OAuth subscription, no per-token billing. The wrapper spawns the CLI in a throwaway tempfile.TemporaryDirectory and strips ANTHROPIC_API_KEY / ANTHROPIC_AUTH_TOKEN from the env so host CLAUDE.md, hooks, and settings don't leak in, and the subscription is used instead of the API key.
  • api — uses the anthropic Python SDK, requires ANTHROPIC_API_KEY. Install with uv sync --extra api (the SDK is an optional dependency).

Requirements

  • Python 3.12+
  • Either the claude CLI on PATH (default backend) or ANTHROPIC_API_KEY (api backend)
  • ffmpeg (for Whisper audio extraction)

In-flight work

  • Postgres + pgvector migration — SQLite is the current backing store but the project is moving to Travis's Postgres instance. Planning questions live in postgres-migration-planning.md; nothing has been migrated yet.
