What it does

Channel Hygiene is an agent skill from mohitagw15856/pm-claude-skills. 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.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Slack. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

When your agent uses it

  • Asked clean up our Slack/Teams
  • We have 90 channels and nothing is findable
  • Set channel norms
  • Where should things get posted

Example prompts

  • “/channel-hygiene”

5 steps, taken from the first numbered list in SKILL.md.

  1. One purpose, stated in the topic: every surviving channel's topic line completes "post here for ___" — channels that need "and" in that…
  2. Prefixes are navigation: #team- (a group's home), #proj- (temporary, archived at ship — the expiry is the point), #help- (questions…

  5. @-signals are priced, urgency is explicit: @-channel = "everyone must see this today" (rare by definition) · @-person = "you specifically…

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Channel Hygiene loads about 1.4k tokens when it runs. Until then it costs about 126 tokens; SKILL.md has 683 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~126
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
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

Required Inputs

Ask for these if not provided:

  • 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

Framework: The Hygiene Rules

  1. One purpose, stated in the topic: every surviving channel's topic line completes "post here for ___" — channels that need "and" in that sentence are two channels; channels where nobody can complete it are archive candidates. The topic line is the routing card at the point of confusion.
  2. Prefixes are navigation: #team- (a group's home), #proj- (temporary, archived at ship — the expiry is the point), #help- (questions, threaded), #ann- (announcements, restricted posting, no discussion) — the sidebar becomes a sorted map, and new-channel creation inherits the scheme's discipline.
  3. Archive without fear, loudly: channels dead >90 days get archived with the announcement stating the two facts that kill the objections: archives are searchable and un-archiving takes one click. Duplicated topics merge into the survivor with a pointer post. The sidebar halving is the visible win that funds the norms' adoption.
  4. Threads keep channels skimmable: discussions thread; the channel surface stays scannable headlines. The norm is stated positively ("thread replies so the channel stays skimmable") and modeled by the leads — thread culture is caught, not decreed.
  5. @-signals are priced, urgency is explicit: @-channel = "everyone must see this today" (rare by definition) · @-person = "you specifically, action expected" · no-@ = ambient. Urgent-and-blocking gets its stated convention (the 🔴 prefix, the #help-urgent lane — whatever's chosen, it's written), because unpriced attention signals inflate until everyone mutes everything — and DMs about team topics get the gentle norm: ask in the channel, so the answer compounds (faq-builder feeds on this).

The Audit

ChannelPurpose (topic-line test)Last activeVerdict

The Map + Scheme

[Prefix taxonomy · surviving channels with written topic lines · the new-channel rule]

The Norms Card (pin this)

[Threads · @-pricing · the urgency convention · where-to-post routing · the ask-in-channel-not-DM nudge]

The Archive Pass

[The list · the merge pointers · the announcement with the two fear-killers]

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

Anti-Patterns

  • 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

Example Trigger Phrases

  • "Clean up our Slack/Teams."
  • "We have 90 channels and nothing is findable."
  • "Set channel norms."
  • "Where should things get posted?"
