Two Windows agent-loop friction fixes:
1. tools/mcp_tool.py (#56536): shutil.which(cmd, path=env_path) reads
executable extensions from the PARENT process PATHEXT, not the MCP
subprocess env — a stdio MCP config supplying both PATH and PATHEXT
could fail to resolve a command its own env can locate, and startup
then got a bare command name. On Windows, when the first which() call
misses and the config env carries PATHEXT (any key casing), retry the
resolution with the config's PATHEXT temporarily applied.
2. skills/ + optional-skills/ (#50606): 42 SKILL.md files that declare
platforms: [.., windows] used python3 in their command examples.
python3 does not exist on native Windows (the toolchain probe in the
system prompt reports python3=missing), so every copy-pasted example
burned a failed agent turn before self-correction. Replaced the
command word python3 -> python (python3-config / python3.x version
strings untouched). python is the spelling that exists in every
Hermes-managed environment (Windows native, uv-managed venvs on all
three OSes); agents on POSIX hosts additionally see the probed
toolchain line and adapt either way.
* chore: re-trigger CI (workflows did not dispatch on prior head)
* feat(skills): add cloudflare-temporary-deploy optional skill
Optional web-development skill teaching the agent to deploy a Worker to a
live workers.dev URL with no Cloudflare account via 'wrangler deploy
--temporary' (Wrangler 4.102.0+). Cloudflare provisions a throwaway,
claimable account valid for 60 minutes — ideal for an autonomous
write->deploy->verify loop with no OAuth/signup hard stop.
- SKILL.md: when/when-not, prereqs (unauth requirement, version floor),
step-by-step deploy + verify flow, product limits table, pitfalls
(hidden flag, stale global wrangler, auth-present error, rate limits,
workers.dev edge cache), verification.
- scripts/parse_deploy_output.py: stdlib-only parser extracting live URL,
claim URL, account name/state, expiry, deploy status from wrangler output.
- tests/skills/test_cloudflare_temporary_deploy_skill.py: 16 tests incl.
a real-output regression case.
Verified live end-to-end: temporary account created with no creds,
deployed to a live URL, curl confirmed body, redeploy reused the account.
