A documentation plugin for writing pages that people can use without knowing the product's implementation. It sets rules for audience, page types, terminology, quality checks, and reader-focused review.

Use it to create and review customer-facing documentation, tutorials, explanations, references, and diagrams.

It prevents user documentation from relying on source-code concepts, unexplained assumptions, or inconsistent structure. It also provides checks for clarity and consistency.

webster — Plugin for Claude Code by alphabravo-oss/guild

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/alphabravo-oss/guild

Made for: Claude Code.

Security

Grade A, and why

webster scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

{
  "name": "webster",
  "version": "0.19.0",
  "description": "Documentation for the person who has to use the thing, held to the bar of something you could hand a customer without reading it first. Every page declares who it is for, and that decides what the page may be about: a page for a user names screens, buttons and what the product gives back, never a symbol, a route or the architecture. Written from the product's own on-screen vocabulary before anyone opens the source. Prose is measured for the shape a reader pays for rather than for syllables, and then read by an agent that knows nothing about the product and reports where the page stopped it. Fixed layout modelled on Harvester, content types from The Good Docs Project, quality checks from the ISO/IEC/IEEE 26514 characteristics. Anchors every claim, measures drift against a recorded manifest, and refuses to state what it could not check.",

Contents

What it installs

The manifest is a name and a version. 11 skills, 6 agents travel with it, and installing the plugin installs all of them — 792 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
