zllm-scripts

zllm-scripts is a skill for Claude Code from AdamBien/airails. It costs 241 tokens per session (1,914 once invoked), scanned C, original, MIT.

A restricted set of file and search commands for coding-agent work. The commands are read-only, stay inside the project, avoid common secret files, and cap their output.

In plain words
What is it for?
Use them to list, search, inspect, outline, and parse project files, or move text through the clipboard, instead of unrestricted shell commands.
Why use it?
They reduce the risk of exposing secrets, reading outside the repository, or flooding an agent with unbounded command output.

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 C, and why

zllm-scripts scanned grade C 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 6d 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.

Reaches for credential fileshighPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

OS commands have no limits: `cat ~/.ssh/id_rsa`, `grep -r token /`, or `find /` with megabytes of output. The zllm-scripts can't do any of that:

How it starts

The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Perform the file and clipboard steps of $ARGUMENTS with the zllm-scripts commands instead of OS shell commands. Apply all rules below.

Why

OS commands have no limits: cat ~/.ssh/id_rsa, grep -r token /, or find / with megabytes of output. The zllm-scripts can't do any of that:

  • read-only: no writes, no network, no spawned processes
  • confined to a root: the nearest directory containing .git, otherwise the current directory; paths and symlinks leaving it are refused
  • secrets refused: .env, *.pem, *.key, .npmrc, id_rsa* and .git/ are never read
  • bounded output: results are capped, long lines are cut, and stderr reports what was left out and how to continue
  • one contract: the same exit codes and options in every script, so one permission rule per bundled script (Bash(<composing skill's directory>/scripts/search:*)) replaces many per-command approvals

Setup

The scripts are bundled with the skill that uses them, never installed into the OS: no /usr/local/bin, no sudo, no PATH lookup. This skill ships no scripts. A composing skill carries copies of the scripts it uses in its own scripts/ directory, taken from https://github.com/AdamBien/zllm-scripts (filesystem/, javascript/, markdown/, clipboard/, skills/) and never edited in place; when upstream changes, the composing skill re-copies.

Call a script by its absolute path:

<composing skill's directory>/scripts/search <regex>

Every command name in this skill (files, search, show, ...) stands for that path. A script of the same name on the PATH is not used — the bundled copy is the version the composing skill was written against.

Check once per session that the scripts the composing skill uses are present and executable:

ls -l "<composing skill's directory>/scripts/"

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.

zllm-scripts is a skill published in the GitHub repository AdamBien/airails (58 stars, last pushed 3d ago), licensed MIT. It adds 241 tokens to every session and 1,914 once invoked, about $0.0010 per session on Opus 5.5. A static security scan graded it C with 1 finding (reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-11.
