codebeacon: Instructions file for Claude Code

CLAUDE.md

codebeacon CLAUDE.md is an instructions file for Claude Code from Wandererer/codebeacon. It costs 594 tokens per session, scanned A, original, MIT.

Instructions for finding information in a repository using a pre-built CodeBeacon index, Obsidian notes, and source files. A repository is the project's stored code and related files.

In plain words
What is it for?
Use it when answering where code is located or tracing how parts of a project connect: check the CodeBeacon wiki, then notes, then the source files, with direct search as a fallback.
Why use it?
It gives coding agents an ordered way to locate routes, controllers, services, entities, and other code without searching the entire project first.

Instructions file for Claude Code

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

This is Wandererer/codebeacon's own configuration. It tells Claude Code how to work on codebeacon 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 codebeacon 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

codebeacon 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.

Lookup strategy

This repo ships a pre-built index in .codebeacon/. Check it first — most "where is X" questions resolve in one read without a full-repo search.

Repo type: single — Single-project repo.

Step 1 — codebeacon wiki

Routes, controllers, services, entities.

.codebeacon/wiki/index.md                    ← global index
.codebeacon/wiki/{project}/controllers/{Name}.md  ← controller logic
.codebeacon/wiki/{project}/services/{Name}.md     ← service methods
.codebeacon/wiki/{project}/entities/{Name}.md     ← data models
.codebeacon/wiki/routes.md                   ← all API routes across projects

Step 2 — obsidian notes

Class-level detail (methods, fields, incoming/outgoing edges) the wiki omits. Look up by class name — replace {project} with the relevant folder:

.codebeacon/obsidian/{project}/{ClassName}.md
Project Notes Example
codebeacon 413 services, 3 entities affected_from_paths.py.md

Step 3 — source file

Open the paths surfaced by Steps 1–2.

Fall back to direct search

Reach for Glob, Grep, or the Explore agent when the index does not cover what you need — new files, deep implementation details, or cross-cutting searches that span projects.

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.
