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 | $0.07488 | $0.07488 |
| Opus 5.5 | $0.02995 | $0.02995 |
| Sonnet 5.5 | $0.01498 | $0.01498 |
| Haiku 4.5 | $0.00749 | $0.00749 |
Grade F, and why
skyrimvr-claude-toolkit CLAUDE.md scanned grade F with 4 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- GENERATED by scripts/gen_agent_trees.py from agent/instructions/core.md + claude.md. Toolkit contributors: edit the source. Your own notes belong in KNOWLEDGEBASE.local.md, which updates never replace. --> Encoded or obfuscated payloadhighSupply chain
base64 or hex that is decoded and executed hides what actually runs from anyone reading the file.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Skyrim modding — agent instructions
Guidance for AI coding agents working in this Skyrim install. Agent-specific notes are at the end of this file.
What This Is
A modded Skyrim installation. Adapt paths and version-specific notes to your Skyrim version: SE, AE, VR, or LE. VR-specific behavior is flagged throughout — never assume SSE behavior equals VR behavior.
setup.sh detects your mod manager and fills in the Key Paths below accordingly. If it detected Mod Organizer 2, read the MO2 note in Key Paths before reading or writing any mod file — MO2 has no real Data/ folder, so the obvious path is the wrong one. See "Mod Manager Layout" in KNOWLEDGEBASE.md.
Key Paths
- Game root:
{{GAME_ROOT}}/ - User INI configs:
{{CONFIG_DIR}}/(Skyrim.ini, SkyrimVR.ini, SkyrimPrefs.ini) - Load order:
{{LOADORDER_DIR}}/loadorder.txtandplugins.txt - SKSE plugins:
Data/SKSE/Plugins/ - Mod data:
Data/(ESPs, BSAs, meshes, textures, scripts) {{MOD_MANAGER_PATHS}}

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.
