Thalamus: Primary Workspace

Thalamus

Shared thinking space between one human and one local AI agent (at a time). Created from .agent/secondbrain-template.md. This file is gitignored — it is local to this workspace instance.

Preferences

  • Default mode: zen (deep work sessions are the norm so far)
  • User prefers terse agent responses with context, not trailing summaries
  • ws CLI is the shared interface — agent should use it, not raw git/cd

Observations

  • Agent repeatedly tries the Skill tool for workspace skills despite instructions saying to read the file directly. Reinforced in AGENTS.md but may need further work if it persists.
  • cwd drift pattern: commands like cd docs/gdd && for f in ... shift the working directory, causing subsequent git commands to need compound cd /path && git add that won't match auto-approve patterns. "Be more careful" is not a reliable fix across session resets — may need structural solution (utility script or explicit instruction).
  • Orientation greeting improved over several iterations: started as an information dump, now brief and human-first. Key learning: defer component scan until after alignment on mode/role.
  • Interestingly the component scan didn't come up at all in a new session focused on implementing the review threads feature. Which probably makes sense, both because that's yggdrasil-specific, and a user may not need to know about all the components unless they're working a crosscutting feature of some sort, especially if they already know exactly what component they want to work on.
  • GDD design and Thalamus brainstormed and implemented in one long session (2026-03-22/23). Design specs, 9 skills, multi-page docs, PR #17 with multi-reviewer triage (CodeRabbit + Copilot).
  • Human observation: what's with the linebreaks in markdown (edit: not visible when Markdown rendered, but can be seen raw) - word wrap is a thing, and arbitrarily ending a line at some character count seems odd. It leads to odd mixed appeareances like right in this section as items I've added do not arbitrarily line break, and as a human having to resize lines repeatedly would be painful.
  • Action: update writing-yggdrasil-docs skill to stop hard-wrapping prose at 72-80 chars. Let editors handle word wrap.
  • The .commits/ bodyfile is the right approach for ws commit file staging (not --add flags). Bodyfile with frontmatter containing files to stage + commit message keeps ws commit yggdrasil .commits/foo.md as a stable auto-approvable pattern. Issue #18 needs updating to reflect this direction.
  • The interaction we had about comments I (human) made here were surprisingly nice. I was able to type here while you (agent) did other work, then I went off to do something else. You finished a step, I approved a test comment, and you noticed plus responded to my stray thoughts. That felt almost like flow shared between two entities and I love the potential there - and at the same time I wonder if that is not Zen - are there two modes where in "Flow" you drift in and out of different tasks while in the zone and maybe as a human oversee multiple agents, while in "Zen" you go for the deep insight in a single topic and avoid external distractions, meaning the second brain file becomes largely input only, with all interactions and housekeeping deferred till later or when explicitly triggered at good checkpoints?
  • Another stray human thought: What if the 2nd brain was in an obsidian vault? Perhaps as a dir tree organized by workspace to avoid edit conflict with sync on
