What is argo CLAUDE.md?

A repository-specific instruction file for Claude Code, the command-line coding agent. It points Claude to Argo's shared agent guide and keeps tool-specific instructions separate from the main workflow.

Use it when Claude Code works on Argo, an LLM-based source-code security auditing pipeline. It helps the agent follow the repository's operating procedure.

It prevents Claude from following a second, potentially inconsistent set of project rules. Shared changes stay in one instruction file.

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	$0.00069	$0.00069
Opus 5.5	$0.00028	$0.00028
Sonnet 5.5	$0.00014	$0.00014

Security

Grade A, and why

argo 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 yesterday.

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

Argo: Claude Code entry point

@AGENTS.md

The imported file is the shared source of repository instructions. For the task's operating procedure, read the agent guide. Keep this adapter small; put shared workflow changes in AGENTS.md, not a second Claude-only manual.

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.
