01

Slack is where decisions go to die

The launch date moved in a thread. The pricing call happened in a huddle. The reasoning behind both is forty screens up in a channel nobody scrolls. Six weeks later someone asks "wait, why did we do that?" and the honest answer is that nobody remembers.

Wikis were supposed to fix this. They did not, because writing things up is a separate chore from deciding them, and chores lose.

Say to Walle
@Walle Log this: we are moving the launch to March 4. Owner is Dana. Put it in the decisions page.
02

Capture without ceremony

With Walle in the channel, capture costs one mention. Decide something, then say so: "@Walle log this: launch moves to March 4, Dana owns comms." Walle writes it to your decisions page in Notion with the date, the owner, and a link back to the thread where it happened.

No form, no template, no "someone should write this down." The someone is Walle, and it was already in the room.

Say to Walle
@Walle What did we decide about pricing tiers, and who disagreed?
03

Retrieval is the point

Capture only matters if you can get it back. Ask Walle what was decided about pricing, and you get the decision, the date, who pushed back, and the link. Onboarding a new teammate stops being an oral history project: they can ask Walle directly and get the real answer with sources.

Walle also remembers context on its own: preferences, running projects, who owns what. The longer it works with your team, the less you have to re-explain.

Say to Walle
@Walle Summarize this thread for the new PM and save it to Notion.
04

Per-thread conversations keep it clean

Every Slack thread is its own conversation with Walle. The debugging session in #eng does not bleed into the pricing discussion in #gtm. Context stays scoped to where the work is happening, which means you can run ten conversations in parallel and each one stays coherent.
