Use it when adding or changing tools or data clients, updating documentation, and checking the project build before committing.
Why use it?

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

speak-for-the-trees-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 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.

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.

What it actually says

Speak for the Trees MCP

Architecture

Multi-agent MCP server organized by domain under src/agents/ (watershed, biodiversity, air, pollution). Each agent registers tools in its tools.ts and data clients live under src/clients/.

Rules

  • Keep README.md in sync with tools. When adding, removing, or renaming a tool, update both the Tools table and the Data Sources table in README.md. Tool names in the README must match the first argument to server.tool() exactly.
  • Export new data clients from the npm library. Every client under src/clients/ must be re-exported from src/clients/index.ts (both the fetch function and the summarize/format function). This is the public API for @offtrailstudio/speak-for-the-trees.
  • Build with npm run build. The build output goes to dist/.
  • Validate changes with npm run build before committing.
Changes

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.
