What is branchpoint CLAUDE.md?

Project instructions for Branchpoint, a local MCP server that stores summaries of Git work separately for each branch. A Git branch is an independent line of development in a repository.

Use them to guide development of Branchpoint’s branch-aware context tools, storage in the repository’s .git/branchpoint/ folder, and related project decisions.

They address the problem of an AI agent mixing decisions from different branches or repeatedly rediscovering the same project context.

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.

Model	Per session	Once invoked
Fable 5.1	$0.05117	$0.05117
Opus 5.5	$0.02047	$0.02047

Security

Grade A, and why

branchpoint 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 2mo 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.

Branchpoint

Concepto

Branchpoint es un servidor MCP (Model Context Protocol) local que audita la rama Git activa del repositorio del usuario y persiste resúmenes de contexto por rama en .git/branchpoint/.

El problema que resuelve: cuando un agente IA (Claude Code, Cursor, Cline) trabaja en un repo con varias ramas activas, no tiene memoria de qué se decidió o se hizo en cada rama. Esto provoca dos síntomas:

Alucinación cruzada de ramas: el agente mezcla contexto de código o decisiones de una rama con el trabajo actual en otra.
Desperdicio de tokens: el agente tiene que re-explorar y re-explicar el estado del proyecto en cada sesión porque no hay memoria persistente ligada a la rama.

Branchpoint expone herramientas MCP que permiten al agente leer y escribir un resumen de contexto asociado a la rama Git activa en el momento, de forma que cambiar de rama cambia automáticamente el contexto relevante.

Modelo de negocio: open-core. El núcleo vive en GitHub como pieza de portfolio técnico. Funcionalidades avanzadas (equipos, sync remoto, etc.) se venderán como versión comercial en Gumroad. Esta decisión de negocio no debe condicionar decisiones técnicas del núcleo open-source salvo que se discuta explícitamente.

Stack decidido

No cambiar estas decisiones sin discutirlo primero.

Node 22 LTS — runtime.
TypeScript en modo strict, ESM puro ("type": "module", module / moduleResolution: NodeNext).
@modelcontextprotocol/sdk v1 (actualmente 1.29.0, fijada sin ^ en package.json) — transporte stdio. Explícitamente NO la v2 beta.
Zod v4 — validación de esquemas de las tools MCP.
tsdown como bundler — NO tsup, que está sin mantener.
pnpm como gestor de paquetes.
Biome — lint + format (sustituye a ESLint + Prettier).
Vitest — testing.
@modelcontextprotocol/inspector — herramienta de testing manual del servidor MCP (se instalará/usará vía npx cuando toque probar, no es dependencia del proyecto).

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.
