elixir-lsp CLAUDE.md

A set of Claude Code instructions for the zircote/elixir-lsp repository, including its purpose, setup command, important files, and coding conventions. It documents a plugin that supports Elixir development through ElixirLS and automated hooks.

In plain words
What is it for?
It helps with setup, locating configuration and hook files, and following conventions such as minimal changes, fast hooks, pattern matching, and pipe operators.
Why use it?
It gives the coding agent the project-specific context needed to make consistent changes in this repository.

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

elixir-lsp 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.

Conventions

  • Prefer minimal diffs
  • Keep hooks fast
  • Use pattern matching extensively
  • Prefer pipe operators for data transformations
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.
