A guided migration for moving a browser extension’s existing affiliate-suppression rules to the standdown library. Affiliate suppression means not activating the extension when another partner’s tracking already appears to own a sale.

For inventorying existing rules, mapping parameters and cookies to standdown concepts, measuring differences, and verifying that the new integration does not allow unsafe extra activations.

It helps preserve current revenue-related behavior during the change. The migration compares the old and new decisions in observation mode before any live cutover.

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	$0.00115	$0.00842
Opus 5.5	$0.00046	$0.00337
Sonnet 5.5	$0.00023	$0.00168
Haiku 4.5	$0.00012	$0.00084

Security

Grade A, and why

adopt 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 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.

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.

adopt-standdown: brownfield migration onto `standdown`

ADOPTING.md at the repo root is the source of truth. This skill is a thin router that walks the agent through its five phases and enforces the one non-negotiable: shadow-observe and reconcile before you cut over — never big-bang-replace revenue-critical stand-down logic.

First, confirm this is a brownfield case: the target already stands down today (Phase 1 grep will show disable_domains, ignore_param, cookie/param checks, a fetched/fallback policy, or "stand down"/"suppress" code). If it has none, stop and use the greenfield setup skill (/standdown:setup) instead.

Then read ADOPTING.md and drive its phases in order. Do not summarize from memory — the detail (grep table, mapping table, invariant constraints, worked Dupe example) lives there.

DETECT — grep the whole repo (background worker, content scripts, and any policy-serving server) and build the detection inventory: one row per rule with network/merchant, exact current behavior, file:line, and any TTL.
MAP — translate each row to exactly one standdown concept via the mapping table (params→landingParams, cookies→cookiePatterns name-only, merchant blocks→disableHosts, own attribution→selfPatterns + selfExemptionScope). Match current fleet behavior, not the full library.
SHADOW — baseline grade → observe-only beside the real path (namespaced shadow key / analytics, no action taken) → reconcile every divergence (safe-stricter / dangerous-more-permissive / needs-human-decision) → flagged cutover (off-by-default) → delete old code last.
GUARD — hold the invariants as hard constraints: no network call in the decision path (I1), fail toward standing down (I3), monotone/never lift an active stand-down (I4), cookie NAMES only (I2).
VERIFY — characterization tests, audit grade ≥ baseline, no-fail-open assertions, flag off by default, old code retained as rollback.

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.

adopt is a skill published in the GitHub repository dupe-com/standdown (5 stars, last pushed 27d ago), licensed MIT. It adds 115 tokens to every session and 842 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
