catalog — with the default ~75 skills the payload was ~14 KB and
``tree.sync()`` rejected the entire slash-command batch (issues
#11321, #10259, #11385, #10261, #10214).
Autocomplete options are fetched dynamically by Discord when the
user types — they do NOT count against the per-command registration
budget. So we register ONE flat ``/skill`` command with
``name: str`` (autocompleted) and ``args: str = ""``. This scales
to thousands of skills with no size math, no splitting, and no
hidden skills. The slash picker also becomes more discoverable —
Discord live-filters by the user's typed prefix against both the

# Attachment download helpers
#
# Discord attachments (images / audio / documents) are fetched via the
# authenticated bot session whenever the Attachment object exposes
# ``read()``. That sidesteps two classes of bug that hit the older
# plain-HTTP path:
#
# 1. ``cdn.discordapp.com`` URLs increasingly require bot auth on
# download — unauthenticated httpx sees 403 Forbidden.
# (issue #8242)
# 2. Some user environments (VPNs, corporate DNS, tunnels) resolve
# ``cdn.discordapp.com`` to private-looking IPs that our
# ``is_safe_url`` guard classifies as SSRF risks. Routing the
# fetch through discord.py's own HTTP client handles DNS
# internally so our guard isn't consulted for the attachment
# path. (issue #6587)
#
# If ``att.read()`` is unavailable (unexpected object shape / test
# stub) or the bot session fetch fails, we fall back to the existing
# SSRF-gated URL downloaders. The fallback keeps defense-in-depth
# against any future Discord payload-schema drift that could slip a
# non-CDN URL into the ``att.url`` field. (issue #11345)
