Matt Van Horn 627947fc2c feat(plugin): publish as Claude Code marketplace plugin
Update .claude-plugin/marketplace.json and plugin.json to v2.9.5 with
full metadata. Add plugin install instructions to README as the
recommended install method. The repo root serves as both the marketplace
and the plugin - skills/last30days/SKILL.md (symlink) is discovered
automatically.

Users can now install with:
  /plugin marketplace add mvanhorn/last30days-skill
  /plugin install last30days@last30days-skill

# feat: Add Gemini CLI Extension Support
## Overview
Add Gemini CLI compatibility to last30days by cherry-picking the good parts from PR #53 (@alexferrari88) and fixing the implementation problems ourselves. Close PR #53 with a thank-you comment crediting the contributor.
Based on the review at `docs/plans/2026-03-08-review-pr-53-gemini-cli-support-plan.md`, we accept the concept but fix the approach to match our "one SKILL.md for all platforms" convention established during Codex compatibility work.
## What We Take from PR #53
| Component | Source | Changes Needed |
|-----------|--------|----------------|
| `gemini-extension.json` | PR #53 | Fix settings format (array, not object), bump version to 2.9.5 |
| Path resolution (for loop) | PR #53 | Take as-is, add to both SKILL.md and variants/open/SKILL.md |
| README.md install section | PR #53 | Take as-is |
## What We Skip from PR #53
| Component | Reason |
|-----------|--------|
| `skills/last30days/SKILL.md` (693-line copy) | Duplicate maintenance nightmare - use symlink instead |
| "or" tool name scattering in SKILL.md | LLMs translate tool intent natively - clutters prompt |
| Gemini tool names in `allowed-tools` | Gemini ignores `allowed-tools`; risks breaking Claude Code |
## Implementation Steps
### 1. Create `gemini-extension.json` (new file)
Based on PR #53 but with correct settings format (array per Gemini CLI docs) and v2.9.5 version.
```json
{
"name": "last30days-skill",
"version": "2.9.5",
"description": "Research a topic from the last 30 days across Reddit, X, YouTube, TikTok, Instagram, Hacker News, Polymarket, and the web.",
"settings": [
{
"name": "Extension Directory",
"description": "Extension installation directory (auto-set by Gemini CLI)",
"envVar": "GEMINI_EXTENSION_DIR",
"sensitive": false
},
{
"name": "ScrapeCreators API Key",
"description": "ScrapeCreators API Key for Reddit, TikTok, and Instagram search (required)",
"envVar": "SCRAPECREATORS_API_KEY",
"sensitive": true
},
{
"name": "OpenAI API Key",
"description": "OpenAI API Key - optional fallback for Reddit discovery",
"envVar": "OPENAI_API_KEY",
"sensitive": true
},
{
"name": "xAI API Key",
"description": "xAI API Key for X/Twitter search (optional)",
"envVar": "XAI_API_KEY",
"sensitive": true
},
{
"name": "OpenRouter API Key",
"description": "OpenRouter API Key (optional)",
"envVar": "OPENROUTER_API_KEY",
"sensitive": true
},
{
"name": "Parallel AI API Key",
"description": "Parallel AI API Key (optional)",
"envVar": "PARALLEL_API_KEY",
"sensitive": true
},
{
"name": "Brave Search API Key",
"description": "Brave Search API Key (optional)",
"envVar": "BRAVE_API_KEY",
"sensitive": true
},
{
"name": "Apify API Token",
"description": "Apify API Token (optional legacy)",
"envVar": "APIFY_API_TOKEN",
"sensitive": true
},
{
"name": "Twitter AUTH_TOKEN",
"description": "Twitter browser AUTH_TOKEN cookie for direct X search (optional)",
"envVar": "AUTH_TOKEN",
"sensitive": true
},
{
"name": "Twitter CT0",
"description": "Twitter browser CT0 cookie (optional, pair with AUTH_TOKEN)",
"envVar": "CT0",
"sensitive": true
}
]
}
```
### 2. Create `skills/last30days/SKILL.md` as symlink
```bash
mkdir -p skills/last30days
ln -s ../../SKILL.md skills/last30days/SKILL.md
```
Gemini CLI discovers skills from `skills/<name>/SKILL.md`. Symlink ensures single source of truth - no drift, no duplicate maintenance. Git tracks symlinks natively on macOS/Linux (Gemini CLI's target platforms).
### 3. Add Gemini paths to SKILL.md for-loop (line ~172)
Add these 3 entries after `"${CLAUDE_PLUGIN_ROOT:-}"`:
```bash
"${GEMINI_EXTENSION_DIR:-}" \
"$HOME/.gemini/extensions/last30days-skill" \
"$HOME/.gemini/extensions/last30days" \
```
### 4. Add same Gemini paths to `variants/open/SKILL.md` for-loop
Same 3 entries, same position.
### 5. Update `README.md` install section
Add Gemini CLI install before existing Claude Code section:
```markdown
### Gemini CLI
\`\`\`bash
gemini extensions install https://github.com/mvanhorn/last30days-skill.git
\`\`\`
### Claude Code / Codex
```
### 6. Close PR #53 with credit
Post comment thanking @alexferrari88, explaining we incorporated their work with modifications, and close the PR. Credit them in the commit message.
## Acceptance Criteria
- [ ] `gemini-extension.json` exists with correct array-format settings
- [ ] `skills/last30days/SKILL.md` is a symlink to `../../SKILL.md`
- [ ] Gemini path entries in SKILL.md for-loop (3 new entries)
- [ ] Gemini path entries in variants/open/SKILL.md for-loop (3 new entries)
- [ ] README.md has Gemini CLI install instructions
- [ ] No changes to `allowed-tools` in any SKILL.md
- [ ] No "or" tool name alternatives in any SKILL.md body
- [ ] Claude Code still works (`/last30days` runs normally)
- [ ] PR #53 closed with credit to @alexferrari88
- [ ] Commit message credits @alexferrari88 as co-author
## Confidence Assessment
**High confidence.** All changes are additive:
- New file (gemini-extension.json) - zero conflict risk
- Symlink (skills/last30days/SKILL.md) - zero conflict risk
- 3 lines added to a for-loop - trivially safe, short-circuits on first match
- README addition - simple text
- No changes to SKILL.md content, allowed-tools, or Python scripts
- No changes that could break existing Claude Code behavior
The only untested aspect is whether Gemini CLI correctly follows the symlink for skill discovery. If symlinks cause issues, fallback is a 2-line SKILL.md stub that imports the root (but this is unlikely - Gemini CLI runs on macOS/Linux where symlinks are native).
