siteone-crawler: Instructions file for Claude Code

CLAUDE.md

siteone-crawler CLAUDE.md is an instructions file for Claude Code from janreges/siteone-crawler. It costs 7,724 tokens per session, scanned A, original, MIT.

A project instruction file for SiteOne Crawler that sets rules for careful, simple, narrowly scoped code changes.

In plain words
What is it for?
Use it when planning, implementing, reviewing, or debugging changes in the crawler codebase.
Why use it?
It reduces guesswork, unnecessary features, broad refactoring, and changes outside the task.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is janreges/siteone-crawler's own configuration. It tells Claude Code how to work on siteone-crawler itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything siteone-crawler configures →

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

siteone-crawler 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 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Core Working Principles

Adapted from Andrej Karpathy's four CLAUDE.md principles — read these before touching code. They target reasoning failures (wrong assumptions, over-engineering, scope creep, weak success criteria), not formatting.

  1. Think Before Coding — Don't assume. Don't hide confusion. Surface tradeoffs.

    • State assumptions explicitly; if uncertain, ask rather than guess.
    • Present competing interpretations instead of silently picking one.
    • Call out inconsistencies, confusion, and tradeoffs as you find them.
  2. Simplicity First — Minimum code that solves the problem. Nothing speculative.

    • No features beyond what was asked.
    • No abstractions for single-use code.
    • No "flexibility" or configurability that wasn't requested.
    • No error handling for scenarios that cannot occur.
  3. Surgical Changes — Touch only what you must. Clean up only your own mess.

    • Match the surrounding style and conventions.
    • Don't refactor unbroken adjacent code that's orthogonal to the task.
    • Only remove what your change rendered obsolete.
  4. Goal-Driven Execution — Define success criteria. Loop until verified.

    • Turn tasks into verifiable goals: "add validation" → "write tests, then make them pass"; "fix the bug" → "reproduce it in a test, then fix"; "refactor X" → "ensure tests pass before and after".
    • Iterate against those criteria instead of asking for constant clarification.

Setup After Clone

git config core.hooksPath .githooks               # enable pre-commit hook (fmt + clippy + tests)

Build & Test Commands

cargo fmt                                         # auto-format code (always run before build)
cargo build                                       # debug build
cargo build --release                             # release build (~11s)
cargo test                                        # unit tests + offline integration tests (~300 tests)
cargo test --test integration_crawl -- --ignored --test-threads=1  # network integration tests (crawls crawler.siteone.io)
cargo test scoring::ci_gate::tests::all_checks_pass  # run a single test by name
cargo clippy -- -D warnings                       # lint (CI enforces zero warnings)
cargo fmt -- --check                              # format check

# Browser rendering (`--browser`, chromiumoxide/CDP) is a DEFAULT feature — `cargo build`,
# `cargo test`, `cargo clippy` all include it. Build/test the lean variant (no chromiumoxide):
cargo build --release --no-default-features        # lean build, ~6 MB smaller, no browser
cargo test --no-default-features                   # tests without the browser feature
cargo clippy --no-default-features -- -D warnings  # lint the lean variant

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.
