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 | $0.00072 | $0.02088 |
| Opus 5 | $0.00036 | $0.01044 |
| Sonnet 5 | $0.00014 | $0.00418 |
| Haiku 4.5 | $0.00007 | $0.00209 |
Grade A, and why
nika-migration 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 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.

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

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.

nika-migration is a skill published in the GitHub repository supernovae-st/nika-plugins (2 stars, last pushed 3d ago), licensed AGPL-3.0. It adds 72 tokens to every session and 2,088 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls).
