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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.00535 |
| Opus 5 | $0.00018 | $0.00267 |
| Sonnet 5 | $0.00007 | $0.00107 |
| Haiku 4.5 | $0.00004 | $0.00053 |
Grade A, and why
skyrim-save 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 12d 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.
What it actually says
Save File Analysis
Use scripts/read-save.py to decompress and scan Skyrim save files. Requires Python with lz4 package (pip install lz4). All output is JSON.
Commands
Get save info (player name, level, location, plugin count):
python scripts/read-save.py info "<path-to-save.ess>"
List all plugins in the save:
python scripts/read-save.py plugins "<path-to-save.ess>"
Search for a string (script names, EditorIDs, variable names):
python scripts/read-save.py search "<save.ess>" --string "MyModScriptName"
Search for a FormID (as hex, little-endian uint32):
python scripts/read-save.py search "<save.ess>" --formid 0x0001ABCD
Search for a raw hex byte pattern:
python scripts/read-save.py search "<save.ess>" --hex "DEADBEEF"
Common Debugging Use Cases
- Orphaned scripts: Search for a script name from a removed mod. If it still appears, the save has orphaned instances.
- Effect accumulation: Search for a spell's FormID and count occurrences. More than expected = stacking bug.
- Mod footprint: Search for a mod's prefix (e.g., "MyMod_") to see how many references it left in the save.
- Save bloat: Compare
decompressedSizeacross saves to detect growth over time.
Save File Structure
SSE/VR saves use LZ4 compression. General layout of the decompressed data:
- 0-100KB: Header, plugin list, screenshot
- 100KB-~22MB: Global data tables, ChangeForms (binary)
- ~22MB+: Papyrus string table, script instances, FormID arrays
Limitations
- Read-only — cannot edit or write back valid saves
- Binary search only — cannot parse structured Papyrus instance data (variable values, active effect state)
- For structured save editing, use ReSaver (Java GUI)
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.

skyrim-save is a skill published in the GitHub repository WingedGuardian/skyrimvr-claude-toolkit (14 stars, last pushed 2d ago), licensed MIT. It adds 37 tokens to every session and 535 once invoked, about $0.0002 per session on Opus 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 2026-08-30.

console-get-logs
Retrieve Unity Editor logs from the MCP plugin's LogCollector, optionally filtered by log type or time window. Useful for debugging and monitoring Editor activity.
editor-application-get-state
Return the current state of UnityEditor.EditorApplication — playmode, paused state, compilation state, and related flags.
console-clear-logs
Clear the MCP log cache (used by 'console-get-logs') and the Unity Editor Console window. Useful for isolating logs to a specific action by clearing the slate first.
profiler-start
Enable Unity's runtime profiler and open the Profiler window. Idempotent: calling when already enabled returns the current enabled state without error.
