Fix PR diff documentation to use git instead of tea

The tea CLI doesn't have a command to output PR diff content directly.
The -f diff flag only returns a URL. Updated docs to use tea pulls
checkout followed by git diff main...HEAD.

-## Invoking Skills
+## Including Skills
 
-Commands reference skills by name to gain domain knowledge. When a skill is referenced, Claude reads the skill file before proceeding.
+Commands include skills using the `@` file reference syntax. This automatically injects the skill content into the command context when the command is invoked.
 
-### Explicit Reference
+### File Reference Syntax
+
+Use the `@` prefix followed by the path to the skill file:
 
 ```markdown
 # Groom Issues
 
-Use the **gitea**, **backlog-grooming**, and **issue-writing** skills.
+@~/.claude/skills/gitea/SKILL.md
+@~/.claude/skills/backlog-grooming/SKILL.md
+@~/.claude/skills/issue-writing/SKILL.md
 
 1. **Fetch the issue** details
 2. **Evaluate** against grooming checklist
 ...
 ```
 
-The phrase "Use the gitea, backlog-grooming and issue-writing skills" tells Claude to read and apply knowledge from those skill files.
+When the command runs, the content of each referenced skill file is automatically loaded into context.
 
-### Skill-Based Approach
+### Why File References?
 
-Commands should reference skills rather than embedding CLI commands directly:
+**DO NOT** use phrases like "Use the gitea skill" - skills have only ~20% auto-activation rate. File references guarantee the skill content is available.
 
-```markdown
+| Pattern | Behavior |
-1. **Fetch the issue** details
+|---------|----------|
-```
+| `@~/.claude/skills/gitea/SKILL.md` | Content automatically injected |
+| "Use the gitea skill" | Relies on auto-activation (~20% success) |
 
-This relies on the `gitea` skill to provide the CLI knowledge.
+### When to Include Skills
 
-### When to Reference Skills
+| Include explicitly | Skip skill reference |

 A guide to creating reusable knowledge modules for the Claude Code AI workflow system.
 
+> **Official Documentation**: For the most up-to-date information, see https://code.claude.com/docs/en/skills
+
 ## What is a Skill?
 
-Skills are **knowledge modules**—focused documents that teach Claude how to do something well. Unlike commands (which define workflows) or agents (which execute tasks), skills are passive: they encode domain expertise, patterns, and best practices that can be referenced when needed.
+Skills are **model-invoked knowledge modules**—Claude automatically applies them when your request matches their description. Unlike commands (which require explicit `/command` invocation), skills are triggered automatically based on semantic matching.
 
-Think of skills as the "how-to guides" that inform Claude's work. A skill doesn't act on its own—it provides the knowledge that commands and agents use to complete their tasks effectively.
+## YAML Frontmatter (Required)
+
+Every `SKILL.md` file **must** start with YAML frontmatter. This is how Claude discovers and triggers skills.
+
+### Format Requirements
+
+- Must start with `---` on **line 1** (no blank lines before it)
+- Must end with `---` before the markdown content
+- Use spaces for indentation (not tabs)
+
+### Required Fields
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `name` | **Yes** | Lowercase letters, numbers, and hyphens only (max 64 chars). Should match directory name. |
+| `description` | **Yes** | What the skill does and when to use it (max 1024 chars). **This is critical for triggering.** |
+
+### Optional Fields
+
+| Field | Description |
+|-------|-------------|
+| `allowed-tools` | **Restricts** which tools Claude can use when this skill is active. If omitted, no restrictions apply. |
+| `model` | Specific model to use when skill is active (e.g., `claude-sonnet-4-20250514`). |
+
+### Writing Effective Descriptions
+
+The `description` field determines when Claude applies the skill. A good description answers:
+
+1. **What does this skill do?** List specific capabilities.
+2. **When should Claude use it?** Include trigger terms users would mention.
+
+**Bad (too vague):**
+```yaml
+description: Helps with documents
+```
+
+**Good (specific with trigger terms):**
+```yaml
+description: View, create, and manage Gitea issues and pull requests using tea CLI. Use when working with issues, PRs, viewing issue details, creating pull requests, adding comments, merging PRs, or when the user mentions tea, gitea, issue numbers, or PR numbers.
+```
+
+### Example Frontmatter
+
+```yaml
+---
+name: gitea
+description: View, create, and manage Gitea issues and pull requests using tea CLI. Use when working with issues, PRs, viewing issue details, creating pull requests, or when the user mentions tea, gitea, or issue numbers.
+---
+
+# Gitea CLI (tea)
+
+[Rest of skill content...]
+```
+
+## Subagents and Skills
+
+Subagents **do not automatically inherit skills** from the main conversation. To give a subagent access to skills, list them in the agent's `skills` field:
+
+```yaml
+---
+name: code-reviewer
+description: Review code for quality and best practices
+skills: gitea, code-review
+---

-## How Skills are Loaded
+## How Skills are Discovered and Triggered
 
-Skills are loaded by **explicit reference**. When a command or agent mentions a skill by name, Claude reads the skill file to gain that knowledge.
+Skills are **model-invoked**: Claude decides which skills to use based on your request.
 
-### Referenced by Commands
+### Discovery Process
 
-Commands reference skills in their instructions:
+1. **At startup**: Claude loads only the `name` and `description` of each available skill
+2. **On request**: Claude matches your request against skill descriptions using semantic similarity
+3. **Activation**: When a match is found, Claude asks to use the skill before loading the full content
 
-```markdown
+### Subagent Access
-# Groom Issues
 
-Use the **backlog-grooming** and **issue-writing** skills to review and improve issues.
+Subagents (defined in `.claude/agents/`) must explicitly list which skills they can use:
 
-1. Fetch open issues...
+```yaml
+---
+name: product-manager
+description: Manages backlog and roadmap
+skills: gitea, issue-writing, backlog-grooming, roadmap-planning
+---
 ```
 
-When this command runs, Claude reads both referenced skills before proceeding.
+**Important**: Built-in agents and the Task tool do not have access to skills. Only custom subagents with an explicit `skills` field can use them.
-
-### Referenced by Agents
-
-Agents list their skills explicitly:
-
-```markdown
-# Product Manager Agent
-
-## Skills
-- gitea
-- issue-writing
-- backlog-grooming
-- roadmap-planning
-```
-
-When spawned, the agent has access to all listed skills as part of its context.
