What is ii-agent AGENTS.md?

Repository instructions for II-Agent, an AI service for internet research, machine-learning engineering, and scientific work. They describe its project structure, commands, architecture, and development rules.

Starting the service, checking its health, understanding its modules, and making changes to authentication, billing, APIs, frontend events, or other documented areas.

They give an agent the context needed to work safely in the right part of the codebase. They also point to guidance for billing, security, frontend behavior, and reliability.

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	$0.03294	$0.03294
Opus 5.5	$0.01318	$0.01318
Sonnet 5.5	$0.00659	$0.00659

Security

Grade A, and why

ii-agent AGENTS.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.

Mandatory Rules

Use uv run for all Python commands (uv run pytest, uv run python ...).
Run Ruff only on the Python files you changed before marking work complete (uv run ruff check --fix-only <changed_python_files>, uv run ruff format <changed_python_files>, uv run ruff check <changed_python_files>, uv run ruff format --check <changed_python_files>). If you changed no Python files, skip Ruff.
Never call CreditService.deduct() directly for LLM/tool billing — use the reservation system (see CLAUDE.md Billing section).
Use Dep aliases everywhere — never bare = Depends(get_x) in function signatures (see CLAUDE.md Dependency Injection Pattern).
Use LLMExecutionService for any new code that calls an LLM outside the agent runtime loop.

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.
