+The `document-skills/` subdirectory contains skills that Anthropic developed to help Claude create various document file formats. These skills demonstrate advanced patterns for working with complex file formats and binary data:
+
+- **docx** - Create, edit, and analyze Word documents with support for tracked changes, comments, formatting preservation, and text extraction
+- **pdf** - Comprehensive PDF manipulation toolkit for extracting text and tables, creating new PDFs, merging/splitting documents, and handling forms
+- **pptx** - Create, edit, and analyze PowerPoint presentations with support for layouts, templates, charts, and automated slide generation
+- **xlsx** - Create, edit, and analyze Excel spreadsheets with support for formulas, formatting, data analysis, and visualization
+
+**Important Disclaimer:** These document skills are point-in-time snapshots and are not actively maintained or updated. Versions of these skills ship pre-included with Claude. They are primarily intended as reference examples to illustrate how Anthropic approaches developing more complex skills that work with binary file formats and document structures.

 Skills are simple to create - just a folder with a `SKILL.md` file containing YAML frontmatter and instructions. You can use the **template-skill** in this repository as a starting point:

+# Agent Skills Spec
+
+A skill is a folder of instructions, scripts, and resources that agents can discover and load dynamically to perform better at specific tasks. In order for the folder to be recognized as a skill, it must contain a `SKILL.md` file. 
+
+# Skill Folder Layout
+
+A minimal skill folder looks like this: 
+
+```
+my-skill/
+  - SKILL.md
+```
+
+More complex skills can add additional directories and files as needed.
+
+
+# The SKILL.md file
+
+The skill's "entrypoint" is the `SKILL.md` file. It is the only file required to exist. The file must start with a YAML frontmatter followed by regular Markdown. 
+
+## YAML Frontmatter
+
+The YAML frontmatter has 2 required properties:
+
+- `name`
+    - The name of the skill in hyphen-case
+    - Restricted to lowercase Unicode alphanumeric + hyphen
+    - Must match the name of the directory containing the SKILL.md
+- `description` 
+    - Description of what the skill does and when Claude should use it
+
+There are 3 optional properties:
+
+- `license`
+    - The license applied to the skill
+    - We recommend keeping it short (either the name of a license or the name of a bundled license file)
+- `allowed-tools` 
+    - A list of tools that are pre-approved to run
+    - Currently only supported in Claude Code
+- `metadata`
+    - A map from string keys to string values
+    - Clients can use this to store additional properties not defined by the Agent Skills Spec
+    - We recommend making your key names reasonably unique to avoid accidental conflicts
+
+## Markdown Body
+
+The Markdown body has no restrictions on it.
