A tool for reading and scanning Skyrim save files, which store a player's game state. It reports save information, lists installed plugins, and searches for script names, form identifiers, text, or raw byte patterns.

Use it to investigate orphaned scripts from removed mods, spell-effect accumulation, a mod's remaining footprint, save bloat, plugin lists, or specific FormIDs and data patterns.

It helps find leftover scripts, repeated effects, mod references, and other signs of save problems without opening the save manually. The results are returned as JSON for easier inspection or automation.

Token cost

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	$0.00091	$0.01820
Opus 5.5	$0.00036	$0.00728
Sonnet 5.5	$0.00018	$0.00364
Haiku 4.5	$0.00009	$0.00182

Security

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 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.

Save File Analysis

Use scripts/read-save.py to decompress and scan Skyrim save files. Requires Python with lz4, pinned and hash-locked (from the toolkit root: python -m pip install --only-binary=:all: --require-hashes -r tools/requirements-tools.lock). 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: A raw script-name hit is an investigation lead. Use structured ReSaver instance/reference data to determine whether instances are orphaned.
Effect accumulation: Raw FormID byte counts do not establish active effects or stacking. Check the structured records and runtime state.
Mod footprint: Search for a mod's prefix (e.g., "MyMod_") to locate candidate bytes; these are not semantic reference counts.
Save bloat: Compare decompressedSize across 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

The binary scanner is read-only — it cannot write back valid saves (to change a save, use the ReSaver CLI below)
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 (21 stars, last pushed yesterday), licensed MIT. It adds 91 tokens to every session and 1,820 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 2026-08-30.
