Lucas Gomide a237ebabba feat: adopt directory-based docs versioning with Edge channel (#6202)
* 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.

## Uso
Ao usar a `ScrapflyScrapeWebsiteTool` com um agente, o agente deverá fornecer a URL do site a ser raspado e pode opcionalmente especificar o formato e opções adicionais de configuração:
```python Code
# Example of using the tool with an agent
web_scraper_agent = Agent(
role="Web Scraper",
goal="Extract information from websites",
backstory="An expert in web scraping who can extract content from any website.",
tools=[scrape_tool],
verbose=True,
)
# Create a task for the agent
scrape_task = Task(
description="Extract the main content from example.com in markdown format.",
expected_output="The main content of example.com in markdown format.",
agent=web_scraper_agent,
)
# Run the task
crew = Crew(agents=[web_scraper_agent], tasks=[scrape_task])
result = crew.kickoff()
```
Para um uso mais avançado com configurações personalizadas:
```python Code
# Create a task with more specific instructions
advanced_scrape_task = Task(
description="""
Extract content from example.com with the following requirements:
- Convert the content to plain text format
- Enable JavaScript rendering
- Use a US-based proxy
- Handle any scraping failures gracefully
""",
expected_output="The extracted content from example.com",
agent=web_scraper_agent,
)
```
## Tratamento de Erros
Por padrão, a `ScrapflyScrapeWebsiteTool` irá lançar uma exceção se a raspagem falhar. Os agentes podem ser instruídos a tratar falhas de forma mais flexível especificando o parâmetro `ignore_scrape_failures`:
```python Code
# Create a task that instructs the agent to handle errors
error_handling_task = Task(
description="""
Extract content from a potentially problematic website and make sure to handle any
scraping failures gracefully by setting ignore_scrape_failures to True.
""",
expected_output="Either the extracted content or a graceful error message",
agent=web_scraper_agent,
)
```
## Detalhes de Implementação
A `ScrapflyScrapeWebsiteTool` utiliza o Scrapfly SDK para interagir com a API Scrapfly:
```python Code
class ScrapflyScrapeWebsiteTool(BaseTool):
name: str = "Scrapfly web scraping API tool"
description: str = (
"Scrape a webpage url using Scrapfly and return its content as markdown or text"
)
# Implementation details...
def _run(
self,
url: str,
scrape_format: str = "markdown",
scrape_config: Optional[Dict[str, Any]] = None,
ignore_scrape_failures: Optional[bool] = None,
):
from scrapfly import ScrapeApiResponse, ScrapeConfig
scrape_config = scrape_config if scrape_config is not None else {}
try:
response: ScrapeApiResponse = self.scrapfly.scrape(
ScrapeConfig(url, format=scrape_format, **scrape_config)
)
return response.scrape_result["content"]
except Exception as e:
if ignore_scrape_failures:
logger.error(f"Error fetching data from {url}, exception: {e}")
return None
else:
raise e
```
