CLAUDE.md

lazy-cat CLAUDE.md is an instructions file for Claude Code from albertobarnabo/lazy-cat. It costs 193 tokens per session, scanned A, original, MIT.

Repository instructions for the lazy-cat project. They ask developers to check whether an existing public API, package, or one-line command can solve a substantial task before writing new code.

In plain words
What is it for?
Use them when deciding whether to implement a feature, generate data, or write a larger code change in that repository.
Why use it?
They reduce unnecessary code and keep changes limited to what was requested.

This is albertobarnabo/lazy-cat's own configuration. It tells Claude Code how to work on lazy-cat 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 lazy-cat 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

lazy-cat 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 20d 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

lazy-cat — coding rules

Before any substantial coding task (new feature, data generation, implementation over ~20 lines): pause and check — does a public API, package, or one-liner already solve this? If yes, use it. Only then proceed with the minimum that solves the problem today.

Before writing each code block: build only what was explicitly asked for. Do not add error handling, tests, type annotations, docstrings, or abstractions unless requested. If something seems worth adding, say so after delivering the output — don't add it unilaterally. Replace old code instead of wrapping it in flags or fallbacks. Never make tests pass by hard-coding or editing them; if a test seems wrong, say so.

Skip both rules for: infra/terraform/k8s, DB queries. Skip the second rule when the user asked for a complete or production-ready implementation.

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.
