showcase

A command for submitting a browser extension’s verified standdown grade to a public showcase. Standdown is a library that prevents an extension from taking affiliate credit when another partner already owns the sale.

In plain words
What is it for?
For generating the showcase submission, creating its verified grade card, and opening a pull request to the standdown project after the user approves publication.
Why use it?
It turns a passing conformance check into a reviewable public submission while requiring confirmation about what information will be disclosed. It only accepts extensions that already have an A or A+ grade.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

showcase 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 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.

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

Publish this extension's standdown grade to the "Graded with standdown" showcase. It must already grade A or A+ on conformanceGrade (if it hasn't been graded, run /standdown:setup first).

Follow ${CLAUDE_PLUGIN_ROOT}/showcase/README.md — or, if unavailable, https://github.com/dupe-com/standdown/blob/main/showcase/README.md. Derive the submission details from this extension's standdown integration (name, policy set, disabled hosts, and — if published — its Chrome Web Store id), generate the submission with the submit tool, build the CI-authoritative card, and open a PR to dupe-com/standdown. Ask me only for my GitHub handle and today's date.

Before opening the PR, tell me exactly what the submission will disclose — for a custom policy set that's my resolved policies + disabled hosts, published to a public Dupe-owned repo — and what it will not send (no self-click ids, keys, user data, or source). Then ask whether to proceed, submit as allPolicies to disclose less, or stop; don't publish without my explicit yes.

If my extension is published, also run the Tier 2 live-verify for an A+. Never hand-edit the generated grade, SHA, card, or SHOWCASE.md — CI re-checks all of it, so a hand-edit just fails the build.

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.
