bd-explore CLAUDE.md

A development guide for Claude Code working on bd-explore, a Python tool and MCP server for querying Beads issue stores and their relationships.

In plain words
What is it for?
Navigating the codebase, understanding search and relationship data, and running targeted or complete tests.
Why use it?
It explains the repository structure, architecture, and test commands so changes can be made in the right place.

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

bd-explore CLAUDE.md scanned grade A with 1 finding 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 yesterday.

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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- **Zero Runtime Dependencies**: The core package, CLI, and MCP server must rely exclusively on Python 3.10+ standard library modules (`sqlite3`, `argparse`, `json`, `pathlib`, `re`, `subprocess`, `urllib`, `dataclasses`

CLAUDE.md - Development & Repository Guide for bd-explore

Overview

bd-explore is a zero-dependency Python tool and MCP server that enables AI agents and developers to query a beads issue store codegraph-style. One query returns verbatim issue content (descriptions, notes, comments, close reasons, memories) along with relationship graphs (blocks, blocked-by, parent-child, mentions, GitHub refs) under a strict token/character budget.

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.

bd-explore CLAUDE.md is an instructions file published in the GitHub repository halaprix/bd-explore (0 stars, last pushed 14d ago), licensed MIT. It adds 863 tokens to every session, about $0.0043 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
