skill-authoring

skill-authoring is a skill for Claude Code, Codex from scitix/siclaw. It costs 40 tokens per session (1,071 once invoked), scanned A, original, Apache-2.0.

A guide for creating and improving Siclaw skills, which are reusable instructions and supporting files for coding agents.

In plain words
What is it for?
Use it to create skill folders, write SKILL.md files, define parameters, add scripts or references, and follow recommended packaging practices.
Why use it?
It helps keep skills consistently structured, documented, and usable by the agent.

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

skill-authoring 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 5d 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.

Skill Authoring Guide

Read this guide before creating a new skill or improving an existing one.

Directory Layout

A skill is a directory package, not a single file. The smallest valid skill is:

<skill-name>/
└── SKILL.md

Optional package files can live beside SKILL.md:

<skill-name>/
├── SKILL.md
├── scripts/        # executable .sh/.py helpers
├── references/     # markdown docs the agent can read
├── examples/       # example inputs/outputs
└── assets/         # small images or other package assets

The directory name must match the name field in SKILL.md. Use uppercase SKILL.md; lowercase skill.md is not canonical.

SKILL.md Format

---
name: <kebab-case-name>
description: >-
  One-line summary. Mention the execution tool if the skill uses scripts.
---

Followed by markdown body:

# <Title>

## Purpose
What problem this skill solves and when to use it.

## Tool
<execution tool invocation — required for script-based skills>
Example: local_script: skill="check-pod-oom", script="check.sh", args="<ns> <pod>"

## Parameters
| Parameter | Required | Description |
|-----------|----------|-------------|
| `<arg1>`  | Yes      | ...         |

## Procedure
Step-by-step actions with concrete commands.

## Examples
Concrete tool invocations with realistic parameters.

Script Execution Modes

Tool Runs where When to use
local_script AgentBox (local) kubectl commands from outside the cluster — most common
host_script A host via SSH Host-level tools on a node reachable via SSH. Preferred over node_script — runs over SSH with no debug pod (lighter, leaves the node untouched)
node_script K8s node (host) Host tools, /proc, /sys, devices, nsenter. The fallback when the node is not an SSH host, or whenever a pod's netns is needed
pod_script Inside a pod Diagnostics inside a running container
node_script + pod Node + pod's network ns Host tools + pod's network view (pass pod= — node + netns resolved automatically)

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.
