overview

A documentation setup that lets people read a site while software agents can also discover and call its information. It provides the same tools through MCP, ordinary HTTP requests, and browser-based WebMCP.

In plain words
What is it for?
Use it to publish agent-readable documentation, expose callable tools, support scripts that use HTTP, and help agents discover the site's pages and APIs.
Why use it?
Without these shared interfaces, each type of user or agent may need a different implementation and receive inconsistent information. This setup defines tools once and reuses them across the available access methods.

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.

agentmods
npx agentmods add agents/duvinc/duvlify/overview
Clone the repo
git clone --depth 1 https://github.com/DuvInc/duvlify
Per session 30 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,412 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 1 finding. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

overview scanned grade A with 1 finding 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 2d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Serving agents

People can read this site. Agents can call it. These are different jobs, so the site serves them through different surfaces.

Surface Who uses it What it is
llms.txt, llms-full.txt crawlers, training pipelines a map of the corpus and the corpus itself, as text
<page>.md, Accept: text/markdown anything that follows a link every page as clean Markdown
/mcp Claude, Cursor, ChatGPT, Claude Code the docs as callable tools
/api/docs/* scripts, curl, anything without MCP the same tools as plain GET
WebMCP agents running inside the visitor's browser the same tools again, registered on the page
/agent-manifest.json the Worker, and anyone curious the outline of every page with line offsets

The first two rows are static. They exist in the build output and cost nothing to serve. The Worker serves the rest, and agents.enabled in src/docs.config.ts turns them all on together.

The four tools

worker/agent/tools.ts defines each tool once, as a name, a description, a JSON Schema and a handler. MCP, HTTP and WebMCP are three adapters over that one array. This is why they always agree on what search means. Adding a new tool takes one entry.

search(query, limit?)

Returns passages grouped by the page they came from.

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.

overview is an agent published in the GitHub repository DuvInc/duvlify (23 stars, last pushed 4d ago), licensed MIT. It adds 30 tokens to every session and 1,412 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
