orkcore-filesystem

orkcore-filesystem is a skill for Claude Code, Codex from tweakoz/orkid. It costs 57 tokens per session (984 once invoked), scanned A, original, MIT.

A reference guide for Orkid's filesystem system, including paths, URI schemes, virtual file devices, and data loading. It explains which source files implement each part.

In plain words
What is it for?
Use it when working with path composition, path expansion, file devices, in-memory files, data blocks, or file input and output.
Why use it?
It helps an agent answer file and path questions using the project's actual interfaces and structure.

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.

Security

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 4d 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.

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:

  1. ~ -> $HOME
  2. key://rest -> registered path + /rest
  3. <key> -> registered path
  4. ${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 24d ago), licensed MIT. It adds 57 tokens to every session and 984 once invoked, about $0.0003 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 2026-09-01.
