+
+## Overview
+
+Skills are self-contained directories that provide agents with domain-specific instructions, references, and assets. Each skill is defined by a `SKILL.md` file with YAML frontmatter and a markdown body.
+
+Skills use **progressive disclosure** — metadata is loaded first, full instructions only when activated, and resource catalogs only when needed.
+
+## Directory Structure
+
+```
+my-skill/
+├── SKILL.md            # Required — frontmatter + instructions
+├── scripts/            # Optional — executable scripts
+├── references/         # Optional — reference documents
+└── assets/             # Optional — static files (configs, data)
+```
+
+The directory name must match the `name` field in `SKILL.md`.
+
+## SKILL.md Format
+
+```markdown
+---
+name: my-skill
+description: Short description of what this skill does.
+license: Apache-2.0                    # optional
+compatibility: crewai>=0.1.0          # optional
+metadata:                              # optional
+  author: your-name
+  version: "1.0"
+allowed_tools:                         # optional
+  - web-search
+  - file-read
+---
+
+Instructions for the agent go here. This markdown body is injected
+into the agent's prompt when the skill is activated.
+```
+
+### Name Constraints
+
+- 1–64 characters
+- Lowercase alphanumeric and hyphens only
+- No leading, trailing, or consecutive hyphens
+
+## Usage
+
+### Agent-level Skills
+
+Pass skill directory paths to an agent:
+
+```python
+from crewai import Agent
+
+agent = Agent(
+    role="Researcher",
+    goal="Find relevant information",
+    backstory="An expert researcher.",
+    skills=["./skills"],  # discovers all skills in this directory
+)
+```
+
+### Crew-level Skills
+
+Skill paths on a crew are merged into every agent:
+
+```python
+from crewai import Crew
+
+crew = Crew(
+    agents=[agent],
+    tasks=[task],
+    skills=["./skills"],
+)
+```
+
+### Pre-loaded Skills
+
+You can also pass `Skill` objects directly:
+
+```python
+from pathlib import Path
+from crewai.skills import discover_skills, activate_skill
+
+skills = discover_skills(Path("./skills"))
+activated = [activate_skill(s) for s in skills]
+
+agent = Agent(
+    role="Researcher",
+    goal="Find relevant information",
+    backstory="An expert researcher.",
+    skills=activated,
+)
+```
+
+## Disclosure Levels
+
+Skills load progressively through three levels:
+
+| Level | What's loaded | When |
+|---|---|---|
+| `METADATA` | Name, description, frontmatter fields | `discover_skills()` |
+| `INSTRUCTIONS` | Full SKILL.md body text | `activate_skill()` |
+| `RESOURCES` | File listings from scripts/, references/, assets/ | `load_resources()` |
+
+During normal agent execution, skills are automatically discovered and activated (promoted to `INSTRUCTIONS`). Use `load_resources()` only when you need to inspect available files programmatically.
+
+## Events
+
+Skill operations emit events via the CrewAI event bus:
+
+| Event | When |
+|---|---|
+| `SkillDiscoveryStartedEvent` | Discovery scan begins |
+| `SkillDiscoveryCompletedEvent` | Discovery scan finishes |
+| `SkillLoadedEvent` | A skill is loaded at metadata level |
+| `SkillActivatedEvent` | A skill is promoted to instructions level |
+| `SkillLoadFailedEvent` | A skill fails to load |
+
+```python
+from crewai.events import BaseEventListener, SkillActivatedEvent
+
+class SkillLogger(BaseEventListener):
+    def setup_listeners(self, crewai_event_bus):
+        @crewai_event_bus.on(SkillActivatedEvent)
+        def on_activated(source, event):
+            print(f"Activated: {event.skill_name}")
+```
