scalex: Instructions file for Claude Code

CLAUDE.md

scalex CLAUDE.md is an instructions file for Claude Code from nguyenyou/scalex. It costs 105 tokens per session, scanned A, original, MIT.

Repository instructions for Scalex, a Scala code-search command-line tool that finds symbols, definitions, and references without an IDE, build server, or compilation.

In plain words
What is it for?
Use them when planning or changing Scalex, searching its Scala source and tests, following its roadmap workflow, and writing generic documentation or code examples.
Why use it?
They give coding agents clear boundaries for searching the project and working on changes. They also prevent company, project, and proprietary-code references from appearing in generated output.

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

scalex 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.

What it actually says

CLAUDE.md

Read and follow docs/DEVELOPMENT.md before working in this repository. It is the shared source of truth for architecture, coding conventions, builds, tests, performance budgets, plugin maintenance, and releases.

Use generic examples only; never include proprietary names or internal details in code, documentation, or communications. Scope Scala searches to src/, tests/, clibase/src/, and graph/src/; exclude ignored benchmark data.

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.
