openweb CLAUDE.md

Project instructions for OpenWeb, a tool that lets an AI agent access websites through an API while people can still use a graphical interface.

In plain words
What is it for?
Install and build OpenWeb, run tests and linting, list available website integrations, execute website operations, and update project and skill documentation.
Why use it?
They give contributors a shared reference for setup, testing, documentation, project structure, and keeping shipped instructions in sync with the software.

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.

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

openweb CLAUDE.md 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 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.

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.

How it starts

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenWeb

Agent-native way to access any website. Bridging agent CLI and human GUI through API.

Quick Start

pnpm install && pnpm build
pnpm test              # run all tests
pnpm lint              # biome lint
pnpm dev sites         # list available sites
pnpm dev <site> <op> '{...}'   # execute an operation

Documentation

  • Shipped skill: skills/openweb/ (SKILL.md router, references, knowledge)
  • Architecture & system docs: doc/main/README.md
  • Dev workflow & guides: doc/dev/development.md
  • Progress history: doc/PROGRESS.md
  • Project docs: projects/active/ (active work) and projects/archive/ (historical docs), symlinked from the sibling openweb-projects repo, commit separately

Documentation Sync

When running /update-doc, also check and sync skills/openweb/ — this repo ships skill docs as a deliverable alongside code. See doc/main/README.md § Skill Documentation for the governing principles and structure. Priority areas: files that reference runtime behavior, CLI flags, x-openweb fields, or transport/auth semantics.

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.
