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 | $0.00104 | $0.03039 |
| Opus 5.5 | $0.00042 | $0.01216 |
| Sonnet 5.5 | $0.00021 | $0.00608 |
| Haiku 4.5 | $0.00010 | $0.00304 |
Grade A, and why
mod-update-check 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mod update check
Every mod is judged against this user's situation, save, load order and install, never in the abstract.
Step 0: establish the situation and intent before proposing changes
Most updates happen mid-playthrough, and that is where they do damage. But not every user is mid-playthrough, and the same user changes situation (a new character, a throwaway test save, a rebuild). The protections that matter for a kept save are wrong for a new game and missing for a kept one, so assume neither.
- Read
## My preferencesinKNOWLEDGEBASE.local.md. It holds what the user told you: whether a save is being kept, what this session is for, and standing rulings ("never remove or reorder mods on this save", "new mods go last", and so on). Those rulings decide what you may even propose, and they outrank the rubric's defaults: the rubric says what a change COSTS, the preferences say what the user will ACCEPT. - Check it still fits this request. Use the current request and session context as well as
the recorded preferences. A missing file alone is not a reason to ask again. If a material fact
remains unknown or contradictory, ask only what you cannot establish; continue independent
read-only work while waiting:
- Is there a save you want to keep playing, or is this a new or throwaway game?
- What is this session for: updates only, new mods too, or fixing one problem?
- Is there anything you do not want touched: removals, load-order changes, particular mods?
- Record the answers in
## My preferences, dated, and apply them. A new ruling stated mid-session goes there in the same turn, so the next session starts with it. Keep the section short: the session context includes at most 4,096 bytes of its body; read the full section if truncated. - If a ruling blocks the move that looks right, say so and propose the compliant one. Do not queue work that breaks a ruling (for example, offering a new mod as the next step while updates are still open). When a material ambiguity remains, ask once and record the answer. These choices do not waive verified backups, write guards or scoped authorization.
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.

mod-update-check is a skill published in the GitHub repository WingedGuardian/skyrimvr-claude-toolkit (21 stars, last pushed yesterday), licensed MIT. It adds 104 tokens to every session and 3,039 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-10-14.
