Channel Hygiene

Q: How do I know the Channel Hygiene output is good?

The skill verifies itself against its own quality checks: Every surviving channel passes the topic-line test; The prefix scheme covers team/project/help/announce with project expiry noted; The archive announcement states searchable + reversible; The norms card fits one screen and is pinned where confusion happens.

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.

What to give it

▸The channel census — the list with member counts and last-activity (export or eyeball); the audit works on inventory, not impressions

▸The recurring confusions — where do announcements go? Why are there three design channels? The map answers the actual questions

▸The platform's mechanics — archiving behavior, thread culture, the tools available (channel descriptions, pinned posts) — norms use what exists

▸The team's @-pain — is @-channel abused? Are DMs swallowing team knowledge? The norms card weights by symptom

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓Every surviving channel passes the topic-line test

✓The prefix scheme covers team/project/help/announce with project expiry noted

✓The archive announcement states searchable + reversible

✓The norms card fits one screen and is pinned where confusion happens

✓@-signals and the urgency convention are written, not folklore

⚠️ What it refuses to do

Do not audit by memory — the census with last-activity dates is the ground truth

Do not delete when archiving exists — reversibility is what makes the pass politically free

Do not create channels per mood — the naming scheme is the door, and the door has a test

Do not let announcements and discussion share a channel — the restricted `#ann-` lane exists so the signal survives

Do not decree thread culture — leads model it for two weeks and it installs itself
