AGENTS.md

This file provides guidance to AI coding agents (Claude Code, Cursor, Copilot, etc.) when working with code in this repository.

Repository Overview

Personal collection of skills for Claude.ai and Claude Code. These skills are tailored to siberiacancode projects and packaged as instructions and scripts that extend agent capabilities.

Creating a New Skill

Directory Structure

skills/
  {skill-name}/           # kebab-case directory name
    SKILL.md              # Required: skill definition
    scripts/              # Required: executable scripts
      {script-name}.sh    # Bash scripts (preferred)
  {skill-name}.zip        # Required: packaged for distribution

Naming Conventions

• Skill directory: kebab-case (e.g., siberiacancode-deploy, log-monitor)
• SKILL.md: Always uppercase, always this exact filename
• Scripts: kebab-case.sh (e.g., deploy.sh, fetch-logs.sh)
• Zip file: Must match directory name exactly: {skill-name}.zip

SKILL.md Format

---
name: { skill-name }
description:
  {
    One sentence describing when to use this skill. Include trigger phrases like "Deploy my app",
    "Check logs",
    etc.,
  }
---

# {Skill Title}

{Brief description of what the skill does.}

## How It Works

{Numbered list explaining the skill's workflow}

## Usage

bash /mnt/skills/user/{skill-name}/scripts/{script}.sh [args]
```

Arguments:

• arg1 - Description (defaults to X)

Examples: {Show 2-3 common usage patterns}

Output

{Show example output users will see}

Present Results to User

Troubleshooting

{Common issues and solutions, especially network/permissions errors}

### Best Practices for Context Efficiency

Skills are loaded on-demand — only the skill name and description are loaded at startup. The full `SKILL.md` loads into context only when the agent decides the skill is relevant. To minimize context usage:

- **Keep SKILL.md under 500 lines** — put detailed reference material in separate files
- **Write specific descriptions** — helps the agent know exactly when to activate the skill
- **Use progressive disclosure** — reference supporting files that get read only when needed
- **Prefer scripts over inline code** — script execution doesn't consume context (only output does)
- **File references work one level deep** — link directly from SKILL.md to supporting files

### Script Requirements

- Use `#!/bin/bash` shebang
- Use `set -e` for fail-fast behavior
- Write status messages to stderr: `echo "Message" >&2`
- Write machine-readable output (JSON) to stdout
- Include a cleanup trap for temp files
- Reference the script path as `/mnt/skills/user/{skill-name}/scripts/{script}.sh`

### Creating the Zip Package

After creating or updating a skill:

```bash
cd skills
zip -r {skill-name}.zip {skill-name}/

End-User Installation

Document these two installation methods for users:

Claude Code:

cp -r skills/{skill-name} ~/.claude/skills/

claude.ai: Add the skill to project knowledge or paste SKILL.md contents into the conversation.

If the skill requires network access, instruct users to add required domains at claude.ai/settings/capabilities.
