Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions subagents; positional $N argument.

This is joshuarichard/StatsPlus-MCP's own configuration. It tells Claude Code how to work on StatsPlus-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 StatsPlus-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

StatsPlus-MCP 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 9d 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.

Environment Variables

Variable Required Description
STATSPLUS_LEAGUE_URL Yes Your league's URL slug, e.g. myleague
STATSPLUS_COOKIE No Session cookie for authenticated access

Authentication note: The StatsPlus API requires you to be logged in to your league at https://statsplus.net/<LGURL> and linked to a team. Pass your session cookie via STATSPLUS_COOKIE in the format sessionid=<value>;csrftoken=<value>.

Both variables are configured in your MCP client config (e.g. ~/.claude/mcp.json).

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.
