channel-hygiene

Fix a team's chat sprawl — the channel map with one purpose per channel, the naming scheme that makes purpose findable, the archive pass for the dead and duplicated, and the posting norms (threads, @-discipline, urgency signals) that keep signal findable. Use when asked clean up our Slack/Teams, we have 90 channels and nothing is findable, set channel norms, or where should things get posted. Produces the channel audit and map, the naming scheme, the norms card, and the archive pass.

# Channel Hygiene Skill

Chat workspaces sprawl by entropy: a channel per whim, three channels where one topic lives, dead projects' channels haunting the sidebar, and every question answered with "wasn't that discussed somewhere?" Hygiene is structural: one purpose per channel (stated in the topic line), a naming scheme that sorts and signals (`#proj-`, `#team-`, `#help-`), an archive pass for the dead (archiving is free and reversible — the fear is misplaced), and posting norms that keep conversations findable — threads for discussions, @-mentions priced honestly, urgency signaled by convention instead of ALL CAPS hope.

## What This Skill Produces

- **The channel audit** — every channel: purpose (stated or guessed), last-activity, overlap verdicts
- **The map and naming scheme** — the prefix taxonomy, the one-purpose rule, topic lines written
- **The norms card** — threads, @-discipline, urgency signals, and where-to-post routing — one screen, pinned
- **The archive pass** — the dead and duplicated archived, with the it's-reversible announcement
