hermes-agent/tests/tools/test_skills_tool.py
Teknium c770515e2b modernize re-added Vercel integrations: SDK 0.7.2, telemetry off, sibling-site wiring 
- Bump vercel SDK pin 0.5.7 -> 0.7.2 (pyproject, lazy_deps) and regenerate uv.lock
- Disable the SDK's new default-on telemetry (VERCEL_TELEMETRY_DISABLED=1
  set before import, user-overridable) per the no-opt-out-telemetry policy
- Move _model_flow_ai_gateway into hermes_cli/model_setup_flows.py (god-file
  decomposition landed after the removal)
- Widen post-removal backend sets that vercel_sandbox missed: terminal_tool
  container_backend + _CONTAINER_BACKENDS, file_tools fallback set,
  env_probe._REMOTE_BACKENDS, approval._should_skip_container_guards,
  prompt_builder probe container_config
- Add terminal.vercel_runtime to config_defaults + TERMINAL_CONFIG_ENV_MAP
- Re-add vercel dependency group to nix #full variant (reverts #33773 workaround)
- Update restored tests to current contracts: upload-only credential sync-back
  (bcfc7458fa), registry-derived provider env list, parametrized backend fixture,
  drop tests superseded on main (slack wizard move #41112, nous status format)

class TestSkillViewCollisionDetection:
"""Regression tests for skill_view name collision handling.
When a skill name resolves to multiple paths across the local skills
dir and external_dirs, skill_view must refuse to guess. Silent
shadowing — where ``/skills`` shows the local version but
``skill_view`` loads the external one — is the bug class this guards
against. Reproduces with `skills.external_dirs` registered in
config.yaml and a same-name skill nested under a category locally.
Adapted from a regression suite originally proposed by @polkn in PR
#6136 (which used local-first precedence). The collision-refusal
behavior preserves the same protection without silently picking a
side, and gives the user an actionable hint (use the categorized
path) to recover.
