v0.3.1 — fix: repository manifest schema
🐛 Hotfix: plugin manifest validation
What broke
The plugin's `repository` field in `plugins/antigravity/.claude-plugin/plugin.json` was an OBJECT (npm convention):
```json
"repository": {
"type": "git",
"url": "https://github.com/MarcosNahuel/antigravity-plugin-cc\"
}
```
But Claude Code's plugin manifest schema requires a STRING:
```json
"repository": "https://github.com/MarcosNahuel/antigravity-plugin-cc\"
```
Symptoms before this fix
If you ran:
```text
/plugin marketplace add MarcosNahuel/antigravity-plugin-cc
/plugin install antigravity@marcosnahuel-antigravity
```
Claude Code would respond `Failed to install: ... invalid manifest file ... Validation errors: repository: Invalid input: expected string, received object` — and the seven slash commands (`/antigravity:research`, `/antigravity:rescue`, `/antigravity:record`, `/antigravity:scrape`, `/antigravity:doc-to-md`, `/antigravity:design-review`, `/antigravity:setup`) would never appear in autocomplete.
This bug was present from v0.1.0 onwards — every previous release had it. It only surfaced when Claude Code's loader applied strict schema validation.
After this fix
A clean install now works end-to-end:
```text
/plugin marketplace add MarcosNahuel/antigravity-plugin-cc
/plugin install antigravity@marcosnahuel-antigravity
Restart Claude Code if asked
/antigravity:
→ autocomplete shows all 7 commands
```
Upgrade
If you're on any prior version:
```text
/plugin uninstall antigravity@marcosnahuel-antigravity
/plugin marketplace update marcosnahuel-antigravity
/plugin install antigravity@marcosnahuel-antigravity
```
Or restart Claude Code after pulling — `/plugin update` should pick up v0.3.1.
Engineering note
npm `package.json` uses `repository: {type, url}`. Claude Code plugin manifest uses `repository: ""`. Different schemas — don't reuse npm habits. This is now documented in `CHANGELOG.md` as a gotcha for future plugin authors.
