robinhood-mcp: Instructions file for Codex

AGENTS.md

robinhood-mcp AGENTS.md is an instructions file for Codex, OpenCode from drasticstatic/robinhood-mcp. It costs 1,325 tokens per session, scanned A, original, MIT.

Project instructions for developing robinhood-mcp, a read-only MCP server that exposes research tools for Robinhood portfolio data. Robinhood is a financial service, and read-only means the server cannot place trades.

In plain words
What is it for?
Use them when installing, linting, testing, or starting robinhood-mcp, or when changing its Python tools and Robinhood data access.
Why use it?
They clarify the project's safety limits, setup, testing, authentication approach, and coding standards for agents working in the repository.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

This is drasticstatic/robinhood-mcp's own configuration. It tells Codex and OpenCode how to work on robinhood-mcp 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 robinhood-mcp 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

robinhood-mcp AGENTS.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.

⚠ FIRST: sync this clone before you touch anything

git pull --rebase --autostash

Run this at the start of every session, before reading deeply or editing. Several agents and Christopher push to these repos — including Cosmos agents that run unattended while nobody is at the machine — so a clone can be behind by the time you open it.

--autostash is what makes this safe on a dirty tree. It stashes uncommitted changes, rebases onto the remote, then reapplies them. Your in-progress work survives. Without it, git pull --rebase refuses to run and you are tempted into something worse.

Why it matters more than it sounds:

  • A stale clone does not fail early. It fails at push time, after the work is done, as a non-fast-forward rejection — the most expensive moment to discover it.
  • The tempting fix at that point is git push --force, which discards whatever someone else pushed in the meantime. Syncing first removes the temptation.
  • If a rebase does conflict, stop and resolve it deliberately. A conflict is information: someone else changed the same lines, and you want to know that before building on top of them.

Fresh clone? Also run sh scripts/install-hooks.sh — git hooks are not version-controlled, so the commit-attribution hook stays inert until this clone is pointed at .githooks/. Details: scripts/README.md.

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.
