metago-shushu-zeri

metago-shushu-zeri is a skill for Claude Code, Codex from metago-ai/metagolifeform. It costs 43 tokens per session (463 once invoked), scanned A, original, MIT.

A date-selection tool that searches a time window for dates meeting chosen rules from a traditional Chinese calendar system. It can apply rules involving calendar symbols, listed day classifications, empty periods, and lunar-mansion symbols.

In plain words
What is it for?
Use it to filter dates by stated constraints and return candidate dates with their related calendar labels. It should not replace medical, investment, legal, or other regulated decision-making.
Why use it?
It replaces manual checking of many dates with a constraint search that returns matching candidates. These traditional symbols are cultural heuristics and do not establish that a date will cause a real-world outcome.

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

metago-shushu-zeri 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 today.

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 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.
