Internal Comms

by Anthropic

Status updates and announcements

120Kestimated installs

What it isAnthropic’s official skill for internal communication: status updates, announcements, and team memos written in a clear, direct voice from the bullet points and context you give it.

When to useRecurring team communication you write weekly anyway. It keeps the format consistent and cuts the drafting time; for substantial documents, use Doc Co-Authoring instead.

Matt Pocock Writing Skills

by Matt Pocock

Article drafting as a guided process

90Kestimated installs

What it isFour separately installable skills that form one long-form writing method: writing-fragments collects your raw material, writing-shape structures it, and writing-beats plans the argument beat by beat - shape and beats are alternative middle stages, pick one per piece - then edit-article rewrites the draft hard.

When to useFor articles and essays where one-shot generation produces generic output. The stages work individually - edit-article alone is a strong editor - but the full method is what turns notes into a piece with an actual argument.

Doc Co-Authoring

by Anthropic

Co-writing docs section by section

85Kestimated installs

What it isAnthropic’s official co-writing skill. It aligns on purpose and audience first, drafts the document section by section, works your feedback in as it goes, and then tests whether a fresh reader would actually understand the result.

When to useWorkplace documents where structure carries the weight - specs, proposals, decision docs, reports. Less suited to short posts, where the process is more ceremony than help.

Writing Guidelines

by Vercel

House style the agent actually follows

50Kestimated installs

What it isVercel’s concrete prose rules packaged as a skill: sentence length, hedging, filler, structure. Instead of editing afterwards, it steers how the agent writes while it writes.

When to useWhen you want a consistent standard across everything the agent produces rather than fixing each draft. Pairs naturally with Humanizer - guidelines steer during, Humanizer cleans after.

Humanizer ZH

by op7418

De-AI-ing Chinese prose

45Kestimated installs

What it isThe Chinese-language adaptation of Humanizer. It targets the patterns that mark machine-written Chinese - translated-sounding constructions, filler transitions, over-formal register - and rewrites them into natural prose.

When to useAny Chinese writing an agent produces that people will actually read. The gap between raw model output and natural prose is even wider in Chinese than in English, and this targets it directly.

Baoyu Translate

by Jim Liu

Three-pass idiomatic translation

40Kestimated installs

What it isA translation skill built on a three-step method: a literal pass, a critique of what reads unnaturally, then an idiomatic rewrite. Strongest for Chinese–English work, where the method originated.

When to useContent you’ll publish, where a literal machine translation isn’t good enough. It costs more tokens than a one-shot translation and earns them on quality.

Humanizer

by Siqi Chen

Stripping AI tells from English prose

40Kestimated installs

What it isThe original de-AI-ing skill. It works from a catalog of documented AI-writing signs - inflated transitions, empty emphasis, formulaic structure - and rewrites drafts so the patterns disappear rather than just get rephrased.

When to useAs a final pass over anything going out under your name. It edits what was written; if you want the agent to write differently in the first place, add Writing Guidelines alongside it.

​

Nature Skills

Academic papers and journal polish

35Kestimated installs

What it isA community suite of 18 academic-writing skills: paper structure, section drafting, polishing prose to journal register, reviewer responses, and figures. Each skill installs separately, and the count shown is the most-installed one (nature-figure) - adoption spreads across the suite rather than pooling in one skill.

When to usePapers, theses, and grant writing - it encodes the conventions reviewers expect instead of leaving them to the model’s defaults. For general articles it over-formalizes; use Matt Pocock Writing Skills instead.

Lara Translate

Context-aware translation at scale

30Kestimated installs

What it isTranslated’s official MCP server for its Lara translation platform: text translation, language detection, and context handling, served from a hosted endpoint with a local npm alternative from the same repository.

When to useVolume translation through a dedicated engine rather than the model itself. The hosted endpoint sets up with a browser login, so there’s no local server to run.

What you needA Lara account, authorized via browser OAuth; free, Pro, and Team tiers are documented.

Stop Slop

by Hardik Pandya

Banning slop phrases outright

25Kestimated installs

What it isA blunt instrument: hard bans on the words and constructions that mark AI slop. No rewriting philosophy, just a list the agent is not allowed to touch.

When to useWhen Humanizer’s full rewrite is more than you want and you just need the worst offenders gone. Cheap to run, easy to keep on permanently.

InstallSkill

​

DeepL

Team translation with glossaries

25Kestimated installs

What it isDeepL’s official MCP server, run locally from npm and backed by the DeepL API: text and document translation, rephrasing, language operations, and your organization’s glossaries.

When to useTeams that already standardize on DeepL and need terminology to stay consistent across translations. For one-off translation, a skill like Baoyu Translate costs nothing.

What you needA DeepL API key and Node.js 18+ - the server runs on your machine via npm.

InstallMCP

​

Crowdin

Localization projects in Crowdin

20Kestimated installs

What it isCrowdin’s official hosted MCP server for localization operations: projects, source strings, translations, and terminology, worked on from inside the agent.

When to useOngoing product localization - many languages, many strings, continuous updates. Not for translating a single document; use DeepL or a translation skill for that.

What you needA Crowdin account with a localization project.

Choose by use case

What are you writing?

→ Matt Pocock Writing Skills - articles and essays that need an actual argument, not a generic draft

→ Doc Co-Authoring - specs, proposals, and decision docs, built section by section

→ Internal Comms - the status updates and announcements you write every week

→ Nature Skills - papers and theses held to journal conventions

Want prose that doesn’t read like AI?

→ Writing Guidelines - steers the style as it writes, so drafts start clean

→ Humanizer - rewrites English drafts against the documented AI tells

→ Humanizer ZH - the same for Chinese, where the gap is wider

→ Stop Slop - a cheap, always-on ban on the worst phrases

Guidelines steer during, Humanizer cleans after - they stack.

No official Grammarly route yet - these target AI tells and house style, not comma-level grammar.

Translating something worth getting right?

→ Baoyu Translate - three-pass idiomatic quality, no account needed

→ Lara Translate - volume through a hosted engine, set up with a browser login

→ DeepL - when a team needs glossaries and consistent terminology

→ Crowdin - ongoing product localization, not a one-off document

The skill needs no account; the MCP servers pay off on volume and shared terminology.
