headless-linux-agents

headless-linux-agents is a skill for Claude Code, Codex from albrand/ai-config-kit. It costs 79 tokens per session (685 once invoked), scanned B, original, no licence file.

A troubleshooting guide for coding agents running on Linux servers without a graphical desktop, such as a VPS. It covers command denials, sandbox failures, permission errors, hanging logins, failed global npm installs, and processes that stop after SSH disconnects.

In plain words
What is it for?
Diagnosing agent failures caused by Linux permissions, sandboxing, user namespaces, SSH sessions, and background-process handling.
Why use it?
It helps identify host operating-system restrictions that can look like bugs in the coding agent. The excerpt does not provide enough detail to describe the exact fixes.

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 B, and why

headless-linux-agents scanned grade B with 1 finding 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

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.
