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 | $0.01958 | $0.01958 |
| Opus 5.5 | $0.00783 | $0.00783 |
| Sonnet 5.5 | $0.00392 | $0.00392 |
| Haiku 4.5 | $0.00196 | $0.00196 |
Grade A, and why
robinhood-mcp 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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.

⚠ 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.
Project Overview
robinhood-mcp is a read-only MCP server that wraps the robin_stocks Python library to provide research tools for Robinhood portfolio data. This is strictly a research/educational tool - no trading functionality is exposed.

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.
