What is ggOceanMaps CLAUDE.md?

Project instructions for using a claude.md file in the ggOceanMaps software project. They cover the project overview, stored project knowledge, common commands, and interactive package loading.

Use them when developing or navigating the MikkoVihtakari/ggOceanMaps project.

They give an agent the project-specific context and commands needed to work in that codebase.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03051	$0.03051
Opus 5.5	$0.01220	$0.01220
Sonnet 5.5	$0.00610	$0.00610
Haiku 4.5	$0.00305	$0.00305

Security

Grade A, and why

ggOceanMaps 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 14d 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.

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.
