marketplace: research Cursor plugin import with no fork and no Cursor specifics #7556

Parent

Refs #7555. Source: PLAN Phase 0, topic poteto-review. Thread: Cursor compatibility (deferred
thread, filed active per Q579).

Depends on

• none: on the frontier now

Outcome

A recorded answer to one question: can Cursor import this marketplace's plugins with no fork and no
Cursor-specific files, and which plugin parts survive the import (skills, hooks, when_to_use,
disallowed-tools, plugin agents). The answer comes from Cursor's official documentation plus a
probe that installs one consolidated plugin in Cursor and records what loads.

Decisions

• Deferred thread: Cursor plugin import with no fork and no Cursor specifics; one research item,
  carried into the plan as an open item (Q579, K46). Origin: owner's (the day-job rollout uses
  Cursor, D71, Q84).
• No option is chosen yet; this item decides. Captured assumption 6: skills, hooks, when_to_use,
  disallowed-tools and plugin agents may not import.
• Gates: the day-job rollout (dependency step 11). Tool per job's disallowed-tools use also
  depends on Cursor support (Q561 research tag).

Key interfaces

From the design's variation verdicts: "Cursor as host: TAGGED-DEFERRED; no verdict recorded
(Q579)." Skill-authoring decisions that this research checks: "fix the Cursor /check collision by
consolidation plus distinct first clauses (D82, Q179, Q186)."

Done when

• A comment on this issue starting Probe result: records the Cursor version, the plugin
  installed, and for each of skills, hooks, when_to_use, disallowed-tools and plugin agents
  whether it loaded, with the date.
• A closing comment records the decision (import works as-is, works with named gaps, or needs a
  fork) with each claim's source: a Cursor docs URL read that day, or the probe.
• Every gap the probe found is either filed as a sub-issue of this item or named in the closing
  comment as accepted.

Out of scope

• Writing Cursor-specific files or forking any plugin.
• Fixing the gaps found; those become their own items.
