command-path-safety

command-path-safety is a skill for Claude Code from RohiRIK/OpenLtm. It costs 19 tokens per session (273 once invoked), scanned A, original, MIT.

Security guidance for running commands and handling file paths as validated inputs. It covers command injection, path traversal, and installer boundaries.

In plain words
What is it for?
Use it when hardening subprocesses, installers, archive extraction, file writes, or other command and path handling.
Why use it?
It reduces the risk that untrusted text changes a command or makes files escape an allowed directory.

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

command-path-safety 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 1mo 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.

  • Enforce path roots for writes, extraction, and installer operations.
  • Review archive and installer behavior for traversal and boundary escapes.

Not This Skill

  • Not for exploit scanning, malware analysis, or final security verdicts.
  • Hand off to @aegis for deep audits, exploitability assessment, or repo-wide review.

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.
