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.

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 | $0.00027 | $0.00434 |
| Opus 5 | $0.00014 | $0.00217 |
| Sonnet 5 | $0.00005 | $0.00087 |
| Haiku 4.5 | $0.00003 | $0.00043 |
Grade A, and why
verify-render 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 yesterday.
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.
**Capability gate first.** This is an OPTIONAL deep check that needs a local shell with `ffmpeg` + `ffprobe` + `curl`. If your client has no Bash/shell tool (e.g. Claude Desktop, web), STOP — you can't run it. Just give What it actually says

Capability gate first. This is an OPTIONAL deep check that needs a local shell with ffmpeg + ffprobe + curl. If your client has no Bash/shell tool (e.g. Claude Desktop, web), STOP — you can't run it. Just give the user the videoUrl and, if they've reported a problem, use /poppify:troubleshoot (pure MCP-tool reasoning, no shell). Only proceed if which ffprobe ffmpeg curl succeeds.
Invoke the poppify-render-debug skill and follow it:
-
If args is a
sessionId, callget_result({ sessionId, apiKey })to fetch thevideoUrl. If args is already a URL, use it directly. -

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.
