A workflow for testing an application through its real user interface from start to finish. It checks the actual page, account, state changes, and visual result rather than relying only on code-level tests.

Use it to verify a feature in a running app, repair what breaks during the test, reload to check persistence, and confirm that the final result really works.

It helps catch failures caused by using the wrong page, user, modal, result, or visual state, including problems that a correct-looking document structure can hide.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00033	$0.05312
Opus 5.5	$0.00013	$0.02125
Sonnet 5.5	$0.00007	$0.01062
Haiku 4.5	$0.00003	$0.00531

Security

Grade A, and why

e2e scanned grade A 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- No UI for the change (scheduled task, API only, webhook): drive it anyway, say that is what you did. `curl` the real endpoint on the running server first, else call the service function in the app's own shell. Assert o

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
