binky AGENTS.md

Project instructions for Binky, a tool that gives each Git worktree its own ports, environment, database slice, and stable URLs.

In plain words
What is it for?
They guide installation and use of Binky’s local service for running development servers, migrations, and other branch-specific work in parallel.
Why use it?
They explain how to use isolated development environments when several agents or branches share one repository, preventing collisions.

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

binky AGENTS.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 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.

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

How it starts

The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Binky for agents

Binky gives each git worktree its own isolated local world — ports, env, a private database slice, and stable URLs — so several agents can work on the same repo in parallel without colliding on ports, databases, or .env. You call Binky; it never drives you.

When to reach for it

  • You're about to run a branch's dev server / migrations while another branch is already up.
  • You need a throwaway but real database for a task, not a mock.
  • You're one of several agents pointed at the same repository.

If you only ever have one world up at a time, you don't need Binky.

Install it as a tool

One line in Claude Code:

claude mcp add binky -- binky mcp

Or with nothing installed, via uvx:

claude mcp add binky -- uvx --from "binky[mcp]" binky mcp

Any MCP client takes the same stdio server as a config block:

{ "mcpServers": { "binky": { "command": "uvx", "args": ["--from", "binky[mcp]", "binky", "mcp"] } } }

Binky is also in the MCP Registry as io.github.andreisilva1/binky, for clients that resolve servers from it.

The tools

binky mcp exposes the same verbs the CLI calls, against the same machine-global daemon:

tool signature does
up up(worktree, root="", group="") Bring a worktree's isolated world online (starts the daemon if needed). Returns its services, ports, and URLs.
down down(worktree, root="") Stop a worktree's processes; keeps its files and ports.
status status() List every worktree on this machine with its state, health, and ports.
env env(worktree, root="") A worktree's live coordinates — service URLs and adapter addresses — to hand to a process or a test run.
verify verify(worktree, root="") Run the project's agents.verify checks against a worktree; returns the pass/fail verdict.

root defaults to the current working directory — pass it when you're operating on a project elsewhere.

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.
