(feat) Add Cursor Marketplace plugin form#119
Merged
Conversation
Ships .cursor-plugin/plugin.json + cursor/plugin-hooks.json so the repo is installable from the Cursor Marketplace, alongside the existing install-cursor.sh flow. The plugin form uses a relative ./scripts/cursor-on-event.sh path (resolved from the plugin root) instead of $HOME/.local/share/..., which let the existing bootstrap script stay unchanged. Adds commands/dash0-configure.md to replace the installer's interactive prompt: end users run /dash0-configure inside Cursor to write the OTLP URL + token to ~/.cursor/dash0-agent-plugin.local.md. release.sh now bumps .cursor-plugin/plugin.json alongside the others, and cursor/README.md documents both install paths.
install-cursor.sh no longer carries a hardcoded VERSION. It queries the GitHub API for the latest release on each run, with DASH0_VERSION as an override for pinning. Removes the failure mode where a release that skipped scripts/release.sh would leave the installer pointing at the previous tag. release.sh and cursor/README.md updated to reflect that install-cursor.sh is no longer part of the version-bump set.

Cursor's user-invocable unit is a skill (SKILL.md with name + description frontmatter), surfaced to the agent semantically. The original commands/ path was a Claude Code shape that Cursor's plugin loader did not pick up during local sideload testing. Replaces commands/dash0-configure.md with skills/dash0-configure/SKILL.md and updates the manifest accordingly. Claude Code's commands/open-session.md and .claude-plugin/plugin.json are unchanged.
Root README is now a hub — it pitches the idea (connect coding agents to Dash0 for deep insight into AI usage) and points at the per-runtime docs. Claude Code docs move to .claude-plugin/README.md (unchanged content, just relocated). New .cursor-plugin/README.md holds end-user-facing Cursor docs: install via Marketplace or shell installer, configure via the dash0-configure skill, verify, uninstall. cursor/README.md becomes the developer reference (build, sideload local changes, cut releases, capture-mode fixtures), with a pointer to the user-facing README. Drops the stale cursor-source-handoff-brief.md — the research it captured has been folded into the integration.

Copied verbatim from cursor/plugin-template@main: scripts/validate-template.mjs Required for Cursor Marketplace submission. The script expects a multi-plugin .cursor-plugin/marketplace.json layout — since this repo is a single plugin, the validator early-returns "Validation passed" without actually checking the manifest. Present-in-repo is what the submission process appears to need; real validation would require either a marketplace-style restructure or a single-plugin validator.

Summary
.cursor-plugin/plugin.json,cursor/plugin-hooks.json, and thedash0-configureskill (underskills/) so the repo is installable from the Cursor Marketplace alongside the existinginstall-cursor.shflow. Cursor's user-invocable unit is a skill (SKILL.mdwithname:+description:frontmatter), not a slash command — agents surface skills by description match rather than literal/nametriggers.install-cursor.shno longer carries a hardcodedVERSION— it queriesapi.github.com/repos/.../releases/lateston each run, withDASH0_VERSION=as an override.
