nango AGENTS.md

nango AGENTS.md is an instructions file for Codex, OpenCode from NangoHQ/nango. It costs 606 tokens per session, scanned A, original, no licence file.

Project instructions for working on Nango, an open-source tool for building product integrations. They explain the repository's coding checks, local servers, worktrees, and remote API setup.

In plain words
What is it for?
Use them to run linting and formatting, start Nango and its web app locally, work in multiple worktrees, and connect to a remote API.
Why use it?
They reduce guesswork when changing the Nango codebase by collecting project-specific commands and development rules in one place.

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

nango AGENTS.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 3d 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 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.
