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 | $0.00215 | $0.02396 |
| Opus 5 | $0.00108 | $0.01198 |
| Sonnet 5 | $0.00043 | $0.00479 |
| Haiku 4.5 | $0.00021 | $0.00240 |
Grade A, and why
necromancy 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 5d 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.
Subtle steeringlowPrompt injection
Instructions that bias recommendations or shape behaviour without the user noticing.
**Honor `truncated`/`nextOffset`/`degraded` honestly.** Every response is capped on both count and bytes. A `truncated: true` on `find_spaces` means more spaces matched than the page returned (`total` says how many) — na Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

necromancy is a skill published in the GitHub repository ryanthedev/herderp (5 stars, last pushed 1mo ago), with no licence file. It adds 215 tokens to every session and 2,396 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 1 finding (subtle steering). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
