What is ii-agent CLAUDE.md?

Project-specific instructions for working on II-Agent, an AI-agent platform built with FastAPI and SQLAlchemy. They describe its domain structure, architecture, database conventions, and important project rules.

Use them when changing II-Agent’s application, domains, configuration, database layer, authentication, storage, or other documented parts of the project.

They give a coding agent the context needed to place changes correctly and follow the project’s existing conventions. This reduces guesswork when navigating the 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	$0.06044	$0.06044
Opus 5.5	$0.02418	$0.02418
Sonnet 5.5	$0.01209	$0.01209

Security

Grade A, and why

ii-agent 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 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.

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.
