+# AGENTS.md
+
+This file provides guidance to AI coding agents (Claude Code, Cursor, Copilot, etc.) when working with code in this repository.
+
+## Repository Overview
+
+A collection of skills for Claude.ai and Claude Code for working with code security. Skills are packaged instructions and scripts that extend Claude's 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., `semgrep-install`, `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
+
+```markdown
+---
+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
+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
+
+{Template for how Claude should format results when presenting to users}
+
+## 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:**
+```bash
+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/admin-settings/capabilities`.
