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 | $0.00057 | $0.00984 |
| Opus 5.5 | $0.00023 | $0.00394 |
| Sonnet 5.5 | $0.00011 | $0.00197 |
| Haiku 4.5 | $0.00006 | $0.00098 |
Grade A, and why
orkcore-filesystem 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 2mo 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Architecture Overview
Path Abstraction (ork::file::Path)
- Unified path supporting native, POSIX, URL, and asset catalog forms
- Path composition:
operator/(),operator+() - Decomposition: protocol, folder, file, extension
- Asset catalog paths:
namespace|assetid(detected via|character) - Filesystem queries:
doesPathExist(),isFile(),isFolder()
Path Expansion (thread-safe)
file::setPathExpander("assetcache", stage_dir / "assetcache");
// Then: "<assetcache>/foo" expands to "/path/to/stage/assetcache/foo"
// Also: "assetcache://foo" works via URI protocol
Expansion order:
~->$HOMEkey://rest-> registered path +/rest<key>-> registered path${ENV_VAR}-> environment variable value
Registered Expanders (from application.cpp)
<staging>/<stage>-> staging directory<assetcache>-><stage>/assetcache<temp>-> temp directory<ork_data>-> orkid data directory- URI protocols:
src://,data://,ork_core://,ork_lev2://
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.

orkcore-filesystem is a skill published in the GitHub repository tweakoz/orkid (35 stars, last pushed 2mo ago), licensed MIT. It adds 57 tokens to every session and 984 once invoked, about $0.0002 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 2026-09-01.
