Coordinate FastMCP SkillsProvider migration to SEP-2640 v1 #129
Description
SEP-2640's Backwards Compatibility section calls coordinating the FastMCP SkillsProvider migration (index.json-era shape → skills/list/skills/get) a near-term Working Group priority. Nothing tracks it.
Tasks: confirm current FastMCP behavior, open/link the FastMCP-side issue, record status in docs/related-work.md.

Status on the three tasks.
FastMCP-side issue: PrefectHQ/fastmcp#5016 (opened 2026-09-05 by @strawgate, links back here). Implementation is in two maintainer PRs: PrefectHQ/fastmcp#5057 (extension,
skills/list,skills/get, typed client; open) and PrefectHQ/fastmcp#5704 (opt-inSkillsDirectoryProviderintegration; draft).Current behavior, confirmed on FastMCP main at e2fcc41 (v4.1.0): resources only. Each skill exposes
skill://{dir}/SKILL.mdand a syntheticskill://{dir}/_manifest. There is noskills/list,skills/getor capability declaration yet.Docs: the FastMCP row in
docs/implementations.mdstill sayspre-v1. I'll open a small PR updating it to in progress with these links.AI disclosure: I used Claude Code to read the code and draft this comment; I reviewed it.
docs(implementations): mark FastMCP as in progress (#159)
