Lucas Gomide 93dafe2637 feat: adopt directory-based docs versioning with Edge channel
Switch docs.crewai.com from navigation-only versioning (every version
selector entry rendered the same docs/<lang>/* source files) to
Mintlify's directory-based versioning so each version selector entry
renders its own snapshot. Add an "Edge" channel under docs/edge/<lang>/*
that always reflects main HEAD for unreleased work, eliminating
pre-release leakage onto frozen release labels. External links to
canonical /<lang>/* URLs are preserved via wildcard redirects that
always land on the current default version.

Layout:
- docs/edge/<lang>/*         rolling source (you edit here)
- docs/edge/enterprise-api.*.yaml
- docs/v<X.Y.Z>/<lang>/*     frozen, immutable snapshots
- docs/v<X.Y.Z>/enterprise-api.*.yaml
- docs/images/               shared, append-only
- docs/docs.json             nav + redirects

URLs follow the Mintlify-idiomatic shape: /edge/<lang>/<page> for
Edge, /v<X.Y.Z>/<lang>/<page> for every frozen snapshot. The wildcard
redirects /<lang>/:slug* -> /<default>/<lang>/:slug* keep stale links
working, and every freeze rewrites them (plus all per-section/per-page
redirects) so destinations always resolve to the current default
without depending on a second redirect hop.

Release flow integration (devtools release):
- New module crewai_devtools.docs_versioning.freeze() materialises
  docs/v<X.Y.Z>/ from docs/edge/, rewrites openapi: refs inside the
  snapshot, inserts the version into every language block in
  docs.json, and refreshes all redirect destinations.
- _update_docs_and_create_pr() in cli.py now calls that freeze during
  Phase 2 of devtools release. Edge changelogs are updated first (so
  the snapshot freeze picks them up), then the snapshot is staged
  alongside docs.json, branched as docs/freeze-v<X.Y.Z>, and the PR
  is titled [docs-freeze] docs: snapshot and changelog for v<X.Y.Z>
  — the title prefix the new CI guard reads.
- The PR still gates tag, GitHub release, PyPI publish, and the
  enterprise release as before; no new PRs are added.
- Pre-releases (1.X.YaN, 1.X.YbN, ...) skip the snapshot — they ride
  Edge — and the docs PR title omits the [docs-freeze] prefix.
- docs_check (AI-generated docs scaffolding) writes to
  docs/edge/<lang>/* so newly-generated unreleased docs land in Edge
  and never accidentally touch a frozen snapshot.

Migration scripts (one-shot):
- scripts/docs/freeze_historical_versions.py reconstructs all 16
  historical snapshots (v1.10.0 .. v1.14.7) from git tags via
  git archive | tar, rewriting openapi: MDX refs so each snapshot
  reads its own enterprise-api YAML rather than the live one.
- scripts/docs/prefix_version_paths.py one-shot-migrates docs.json:
  rewrites every page path in 16 versioned blocks to point under
  docs/v<X.Y.Z>/, inserts a new Edge entry per language, tags
  v1.14.7 as Latest (default), prunes pages whose target file
  doesn't exist in the snapshot (e.g. docs/ar/ didn't exist before
  v1.12.0), and writes the wildcard + per-section redirects.
- scripts/docs/freeze_current_edge.py is now a thin CLI wrapper
  around docs_versioning.freeze for manual one-off freezes (e.g.
  retroactively snapshotting a forgotten release).

CI guards (.github/workflows/docs-snapshots.yml):
- Frozen snapshots under docs/v[0-9]*/ are immutable; only PRs whose
  title contains [docs-freeze] (i.e. release-cut PRs generated by
  devtools release or the manual wrapper) may modify them.
- Images under docs/images/ are append-only since snapshots share a
  single image directory. Deleting or renaming an image breaks every
  historical snapshot that still references it.

Restored docs/images/crewai-otel-export.png from PR #3673; it was
deleted in PR #4908 but v1.10.0 / v1.10.1 snapshots still reference
it. Restoring instead of editing the snapshots preserves historical
rendering fidelity and validates the new append-only rule
retroactively.

Tests:
- lib/devtools/tests/test_docs_versioning.py covers the freeze: file
  copy, openapi rewrite, version insertion, default demotion, redirect
  upserts, per-section redirect rewriting, idempotency, and invalid
  inputs.

Verified locally with mintlify broken-links: 0 broken links across
the full site (Edge + 16 frozen versions, 4 locales).

AGENTS.md (repo root) is the contributor guide for the new model;
RELEASING.md is the release-cut runbook; README's Contribution
section links to both.

title: 커스텀 도구 생성
description: CrewAI 프레임워크 내에서 커스텀 도구를 제작, 사용 및 관리하는 종합 가이드로, 신규 기능과 오류 처리를 포함합니다.

## CrewAI에서 툴 생성 및 활용
이 가이드는 CrewAI 프레임워크를 위한 커스텀 툴을 생성하는 방법과 최신 기능(툴 위임, 오류 처리, 동적 툴 호출 등)을 통합하여 이러한 툴을 효율적으로 관리하고 활용하는 방법에 대해 자세히 안내합니다. 또한 협업 툴의 중요성을 강조하며, 에이전트가 다양한 작업을 수행할 수 있도록 지원합니다.
<Tip>
**커뮤니티에 도구를 배포하고 싶으신가요?** 다른 사용자에게도 유용한 도구를 만들고 있다면, [커스텀 도구 배포하기](/ko/guides/tools/publish-custom-tools) 가이드에서 도구를 패키징하고 PyPI에 배포하는 방법을 알아보세요.
</Tip>
### `BaseTool` 서브클래싱
개인화된 툴을 생성하려면 `BaseTool`을 상속받고, 입력 검증을 위한 `args_schema`와 `_run` 메서드를 포함한 필요한 속성들을 정의해야 합니다.
```python Code
from typing import Type
from crewai.tools import BaseTool
from pydantic import BaseModel, Field
class MyToolInput(BaseModel):
"""Input schema for MyCustomTool."""
argument: str = Field(..., description="Description of the argument.")
class MyCustomTool(BaseTool):
name: str = "Name of my tool"
description: str = "What this tool does. It's vital for effective utilization."
args_schema: Type[BaseModel] = MyToolInput
def _run(self, argument: str) -> str:
# Your tool's logic here
return "Tool's result"
```
### `tool` 데코레이터 사용하기
또는 tool 데코레이터 `@tool`을 사용할 수 있습니다. 이 방법은 함수 내에서 도구의 속성과 기능을 직접 정의할 수 있도록 하며, 귀하의 필요에 맞춘 특화된 도구를 간결하고 효율적으로 생성할 수 있는 방법을 제공합니다.
```python Code
from crewai.tools import tool
@tool("Tool Name")
def my_simple_tool(question: str) -> str:
"""Tool description for clarity."""
# Tool logic here
return "Tool output"
```
### 도구를 위한 캐시 함수 정의하기
도구의 성능을 캐싱으로 최적화하려면, `cache_function` 속성을 사용하여 사용자 맞춤 캐싱 전략을 정의할 수 있습니다.
```python Code
@tool("Tool with Caching")
def cached_tool(argument: str) -> str:
"""Tool functionality description."""
return "Cacheable result"
def my_cache_strategy(arguments: dict, result: str) -> bool:
# Define custom caching logic
return True if some_condition else False
cached_tool.cache_function = my_cache_strategy
```
### 비동기 도구 생성하기
CrewAI는 논블로킹 I/O 작업을 위한 비동기 도구를 지원합니다. 이는 HTTP 요청, 데이터베이스 쿼리 또는 기타 I/O 바운드 작업이 필요한 경우에 유용합니다.
#### `@tool` 데코레이터와 비동기 함수 사용하기
비동기 도구를 만드는 가장 간단한 방법은 `@tool` 데코레이터와 async 함수를 사용하는 것입니다:
```python Code
import aiohttp
from crewai.tools import tool
@tool("Async Web Fetcher")
async def fetch_webpage(url: str) -> str:
"""Fetch content from a webpage asynchronously."""
async with aiohttp.ClientSession() as session:
async with session.get(url) as response:
return await response.text()
```
#### 비동기 지원으로 `BaseTool` 서브클래싱하기
더 많은 제어를 위해 `BaseTool`을 상속하고 `_run`(동기) 및 `_arun`(비동기) 메서드를 모두 구현할 수 있습니다:
```python Code
import requests
import aiohttp
from crewai.tools import BaseTool
from pydantic import BaseModel, Field
class WebFetcherInput(BaseModel):
"""Input schema for WebFetcher."""
url: str = Field(..., description="The URL to fetch")
class WebFetcherTool(BaseTool):
name: str = "Web Fetcher"
description: str = "Fetches content from a URL"
args_schema: type[BaseModel] = WebFetcherInput
def _run(self, url: str) -> str:
"""Synchronous implementation."""
return requests.get(url).text
async def _arun(self, url: str) -> str:
"""Asynchronous implementation for non-blocking I/O."""
async with aiohttp.ClientSession() as session:
async with session.get(url) as response:
return await response.text()
```
이 가이드라인을 준수하고 새로운 기능과 협업 도구를 도구 생성 및 관리 프로세스에 통합함으로써,
CrewAI 프레임워크의 모든 기능을 활용할 수 있으며, AI agent의 개발 경험과 효율성을 모두 높일 수 있습니다.
