standdown AGENTS.md

Integration instructions for standdown, a browser-extension library that decides when an extension should stay quiet because a partner already owns an affiliate referral.

In plain words
What is it for?
Use it when adding standdown to a browser extension or shopping tool, including choosing an integration approach and preserving its safety rules.
Why use it?
It helps prevent an extension from taking credit for another partner’s sale while keeping the decision local and advisory.

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 C, and why

standdown AGENTS.md scanned grade C 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 2d 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.

AGENTS.md — integrating standdown

Instructions for an AI coding agent (Claude Code, etc.) adding the standdown library to a browser extension or shopping tool. Copy this file — or point your agent at it — and follow the steps in order.

Developing standdown itself (not integrating it)? See README.md and CONTRIBUTING. This file is the consumer playbook.

What standdown is (read first)

standdown decides, client-side, whether your extension should stand down (stay quiet) because a partner already owns the current affiliate attribution — so you don't hijack a sale someone else referred. It is advisory: it returns a Decision; it never redirects, blocks, or fires anything itself. You own the side effects. Keep these invariants intact when you integrate:

  • Decisions are local and synchronous. Never add a network call to the decision path.
  • Signals are a closed type. Never feed user identity, account, balance, or login state into it.
  • Fail toward standing down. On unknown/ambiguous/error states, suppress.

Step 0 — Greenfield or brownfield?

Decide which integration this is before touching code:

  • Brownfield — the extension already has its own affiliate stand-down / attribution logic: a disable/merchant list, ignore_param or self-click handling, cookie- or param-based stand-down checks, a FALLBACK_POLICY, or any "stand down" / "suppress" code. Stop and follow ADOPTING.md instead. It moves the existing decision path onto standdown in shadow mode — running both in parallel and proving they agree before cutover — so no live commission is put at risk. Do not do the greenfield steps below.
  • Greenfield — no existing stand-down logic. Continue with Step 1.

Grep to decide: affiliate params (cjevent, ranSiteID, irgwc, mkcid, awc), redirect/link-rewrite/cookie-write code, and the words "stand down", "suppress", or "disable". Any real hit → treat it as brownfield and switch to ADOPTING.md.

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.

standdown AGENTS.md is an instructions file published in the GitHub repository dupe-com/standdown (5 stars, last pushed 20d ago), licensed MIT. It adds 2,669 tokens to every session, about $0.0133 per session on Opus 5. A static security scan graded it C with 1 finding (nullifies safety policies). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
