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 5.1 | $0.00024 | $0.00218 |
| Opus 5 | $0.00012 | $0.00109 |
| Sonnet 5 | $0.00005 | $0.00044 |
| Haiku 4.5 | $0.00002 | $0.00022 |
Grade A, and why
verify-packaged-assets 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 10d 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
Verify this installed Agent Plugin package using the materialized skill path appended below.
Inputs — the values arrive in the ## Inputs block below these instructions:
message— the argument to pass through to the packaged script.
- Read
references/live-verification.mdbeneath the materialized skill path withsandbox__read_file. - Extract the exact
verification-tokenvalue from that reference. - Call
sandbox__run_scriptwith:- plugin_id:
portable_security_review - skill_id:
verify_packaged_assets - script:
verify_package.sh - arguments: the
messageinput, as a single-element array
- plugin_id:
- Return the reference token, the script's return code, and its exact stdout. Do not claim success unless both the file read and script call succeed.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

verify-packaged-assets is a skill published in the GitHub repository mappedsky/seizu (5 stars, last pushed today), licensed Apache-2.0. It adds 24 tokens to every session and 218 once invoked, about $0.0001 per session on Opus 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.
