Neel's Plugin Marketplace

You run marketing for a single brand, an agency portfolio, or a content team — and you want the same depth across every brand, every article, every campaign, with no per-platform lock-in. You don't want to learn six different "AI marketing" SaaS UIs that all charge per-seat per-month.

Install three open-source plugins from one marketplace. Same skills, same agents, same outputs across Claude Code, Anthropic Cowork, OpenAI Codex, Cursor 2.5+, GitHub Copilot CLI, Google Antigravity 2.0, Hermes Agent, and OpenClaw + 35+ additional Agent Skills platforms — via the Agent Skills open standard. Zero global hooks, zero auto-connecting MCP servers, MIT-licensed, no telemetry, no seats.

🆕 June 9, 2026 — marketplace v3.13.1: Test-infra polish across the suite — CF v3.15.1 + SF v1.12.1 add release-consistency suites (+61 tests). Suite total 221 tests passing (DMP 114 + CF 53 + SF 54). Every cross-manifest version drift, broken anchor, stale install command, and missing critical section is now caught by python -m unittest discover -s tests before it ships. v3.13.0 (earlier today) brought CF + SF to native Hermes Agent + OpenClaw parity with DMP. All 3 plugins on all 8 native platforms + 35+ Agent Skills clients. Read what's new → · Full changelog →

A custom plugin marketplace by Indranil Banerjee · LinkedIn · X. Agent Skills was donated to the Agentic AI Foundation December 2025; adopted by 41+ agent products by June 2026.

Which plugin do I need?

The three plugins are complementary, not overlapping. A typical agency workflow uses all three: DMP for strategy + campaign planning, ContentForge for the long-form articles a campaign produces, SocialForge for the social assets a campaign produces. All three share the same brand-state directory (~/.claude-marketing/<brand>/) so a brand profile created in DMP is immediately picked up by CF and SF.

Who this suite is for

What's new

v3.13.1 (June 9, 2026) — Suite-wide test-infrastructure polish

CF v3.15.0 → v3.15.1 + SF v1.12.0 → v1.12.1. DMP unchanged at v3.13.1. Mirrors DMP's v3.13.1 test-infra polish into the other two plugins.

• CF release-consistency suite added (tests/test_release_consistency.py, +30 tests; CF total 23 → 53)
• SF release-consistency suite added (+31 tests; SF total 23 → 54)
• Suite total: 160 → 221 tests passing (DMP 114 + CF 53 + SF 54)
• Each suite catches: cross-manifest version drift (7 manifest files per plugin), README badge staleness, hero-callout drift, CHANGELOG out-of-sync, install commands going missing, critical README sections going missing, internal anchor links pointing at non-existent headings, byte-identical description sharing across the 5 Claude-family manifests, and skill-count claims that don't match skills/ directory contents
• SF descriptions sharpened: all 5 Claude-family manifests now lead with 16 skills (was a generic feature list) — better marketplace search relevance + the new test enforces the count going forward
• SF README fixed: broken internal anchor #current-release-v182 re-pointed at the live Current Release section

v3.13.0 (June 9, 2026) — Suite-wide multi-harness parity

CF v3.14.0 → v3.15.0 + SF v1.11.0 → v1.12.0. DMP unchanged at v3.13.1. Brings ContentForge + SocialForge into native Hermes Agent + native OpenClaw parity with DMP. Now all 3 plugins ship plugin.yaml + __init__.py (Hermes adapter) + openclaw.plugin.json at their repo root, plus a stdlib-unittest suite.

• All 3 plugins now on 8 native platforms (Claude Code · Cowork · Codex · Cursor · Copilot CLI · Antigravity · Hermes Agent · OpenClaw) + 35+ Agent Skills clients
• Tests across the suite: 160 passing (DMP 114 + CF 23 + SF 23) — was 0 in CF + SF before this release
• Skill counts unchanged: DMP 158 + CF 21 + SF 16 = 195 total

v3.12.1 (June 9, 2026) — DMP test infrastructure hardening

DMP v3.13.0 → v3.13.1. CF + SF unchanged. Test suite expanded 70 → 114 with cross-manifest drift detection. New tests/test_release_consistency.py (25 tests) catches version drift, README badge staleness, CHANGELOG out-of-sync, install commands going missing, critical sections going missing, broken anchor links. New tests/test_hermes_edge_cases.py (10 tests) for adapter resilience. New README sections: "Get started in 5 minutes (non-developer path)" + "Troubleshooting" covering all 8 native platforms.

v3.12.0 (June 9, 2026) — DMP Hermes Agent + OpenClaw + 40+ Agent Skills

DMP v3.12.1 → v3.13.0. CF + SF unchanged. Native Hermes Agent plugin (plugin.yaml + Python adapter at repo root walking skills/ and registering via ctx.register_skill()). Native OpenClaw manifest (openclaw.plugin.json with skills: ["./skills"]). 35 additional Agent Skills platforms documented (Goose, OpenHands, OpenCode, Junie, Gemini CLI, Roo Code, Kiro, Letta, Amp, and 26 more). Test count 49 → 70.

v3.11.1 (June 8, 2026) — Discoverability + documentation polish

DMP v3.12.0 → v3.12.1. CF + SF unchanged. README "Who this is for" audience table (agencies / in-house / automation builders / consultants / growth / compliance). "How does this compare?" table vs Anthropic Marketing, Composio Marketing, claude-seo. "Real workflows you'd actually run" with 6 copy-paste examples. Recent-release callout at top. 2 new FAQ entries (Cowork persistence + model freshness). GitHub repo descriptions + topics refreshed across all 4 repos for SEO.

v3.11.0 (June 8, 2026) — DMP Cowork persistence + fallback models + tests

DMP v3.11.0 → v3.12.0. CF + SF unchanged. Research-grounded hardening pass after web research confirmed ${CLAUDE_PLUGIN_DATA} is NOT persistent across Anthropic Cowork sessions (GitHub issue #51398). DMP now ships a new /digital-marketing-pro:cowork-setup skill that routes brand state through a Google Drive MCP. Plus fallbackModel chain in settings.json.example, requiredMinimumVersion: 2.1.157 in plugin.json, model-registry freshness check in /doctor, 49-test stdlib suite.

What's new in v3.10.0 (June 4, 2026) — DMP v3.11.0 SEO expansion

DMP bumped 3.10.1 → 3.11.0. CF + SF unchanged. Three new SEO skills (keyword-cluster / backlink-gap / seo-drift) + pattern upgrades across 10 existing SEO skills (Confirm-Then-Dispatch dispatcher, numbered intermediate-file output, quality scorecards). See DMP CHANGELOG.md for the full entry.

What's new in v3.9.0 (June 4, 2026)

Coordinated platform-refresh release: DMP v3.10.0 + SF v1.11.0. Every claim verified against primary sources before code changes.

• DMP ships a new /digital-marketing-pro:gsc-ai-performance skill for the Google Search Console AI Performance Report rolled out 3 June 2026, plus a new skills/context-engine/eu-code-of-practice.md reference doc for EU AI Act Article 50 transparency. Updates to aeo-geo, aeo-audit, c2pa-metadata, paid-advertising (Google Ads API v24 breaking changes), analytics-insights + attribution-report (GA4 AI Assistant channel group added 13 May 2026).
• SF ships C2PA spec refresh — Content Credentials 2.3 expanded formats + Spec 2.4 c2pa.ai-disclosure assertion for Article 50 deployer compliance.

🚀 Quick Start

1. Add this marketplace to Claude

/plugin marketplace add indranilbanerjee/neels-plugins

In Cowork: Settings → Plugins → Add Marketplace → paste indranilbanerjee/neels-plugins.

2. Browse available plugins

/plugin list neels-plugins

3. Install a plugin

/plugin install contentforge@neels-plugins

(Replace contentforge with digital-marketing-pro or socialforge as desired.)

4. Stay current — turn auto-update on (recommended)

Third-party marketplaces have auto-update OFF by default in Claude Code. When we ship a new ContentForge / DM Pro / SocialForge release, you will not be notified — you will keep running whatever version you installed first.

To get future updates automatically: open /plugin, go to the Marketplaces tab, find neels-plugins, and toggle Enable auto-update. After an auto-update fires you will be prompted to run /reload-plugins to pick up changes mid-session (no full Claude Code restart needed; conversation context preserved).

To update manually instead, see the Updating section below.

📦 Available Plugins

v3.7.0 (2026-05-27): real native manifests for 5 surfaces. Ships verified-real manifests for OpenAI Codex (.codex-plugin/plugin.json per the published OpenAI schema), Google Antigravity 2.0 (gemini-extension.json at repo root per Google's gemini-cli-extensions/data-agent-kit-starter-pack reference pattern), Cursor 2.5+ (.cursor-plugin/plugin.json per the verified Cursor JSON Schema), and GitHub Copilot CLI (.github/plugin/plugin.json per the verified GitHub schema). All three plugins ship matching native manifests in their own repos at the same version bump (DMP 3.8.0 / CF 3.13.0 / SF 1.9.0). Replaces the v3.5-v3.6 era invented manifests that were correctly removed in marketplace v3.6.0 on 2026-05-26. Pre-flight verified: all 190 skills across the 3 plugins pass the Codex [a-z0-9-] regex.

🌐 Platform Compatibility

ContentForge v3.9.1's connectors reference catalog includes Pipedream, Composio, Zapier, and Make.com aggregator MCPs that cover Google Sheets/Drive and 1000+ other SaaS services — these are the recommended path for Cowork users.

🛡️ Compliance

All three plugins are designed to comply with the Anthropic Software Directory Policy:

• No financial transaction processing
• No advertising or ad-serving
• No circumvention of Claude safety guardrails
• AI-generated images (where supported) require explicit user approval and are produced in a clear marketing-content context
• All MCP connectors use OAuth 2.0 or API-key authentication via the connector provider's official endpoint

🧠 Shared model curator (v3.5.1+)

All three plugins ship the same model-selection infrastructure under scripts/:

• `model_registry.json` — single source of truth for every AI model id used by the plugin (Claude / GPT / Gemini / Imagen / Veo / Kling / Higgsfield), with vendor, tier, modality, status, and replacement_id for deprecated entries.
• `resolve_model.py` — resolver. Aliases like latest-balanced-anthropic, latest-image-google, latest-video-wavespeed resolve to concrete ids at call time; deprecated ids passed via --model auto-fall-forward to their replacement with a stderr warning.
• `refresh_models.py` — polls Anthropic / OpenAI / Google list endpoints with your API keys and reports drift versus the registry.

Why it matters: frontier models change every ~6 weeks. Hardcoding claude-sonnet-4-5-20250929 or veo-2.0-generate-001 across dozens of scripts means a provider deprecation silently 404s. The curator prevents that. Each plugin documents the alias map at docs/MODEL-CURATOR.md.

🔧 For Developers

Adding a New Plugin to This Marketplace

1. Create your plugin with a .claude-plugin/plugin.json manifest (include $schema, name, version, description, author, homepage, repository, license, keywords).
2. Push it to its own GitHub repository with a LICENSE file.
3. Add an entry to .claude-plugin/marketplace.json in this repo with the source: { source: "github", repo: "owner/repo" } format.
4. Bump the marketplace metadata.version (semver: minor bump for a new plugin or feature release in an existing plugin; patch for hotfixes).
5. Commit and push — the marketplace updates instantly.

Plugin Coexistence Pattern

All three plugins follow a strict "no global side-effects" pattern as of May 2026:

• hooks/hooks.json ships as {"hooks":{}}. Plugin hooks fire globally on every Claude Code operation regardless of working directory, so embedding compliance/verification logic in hooks pollutes unrelated work. The work lives instead in agent files (where it runs in proper context) and Quality Gate criteria.
• .mcp.json ships as {"mcpServers":{}}. Plugin-bundled MCP servers auto-connect on plugin enable, which means shipping N servers triggers N connection attempts (and likely auth prompts) for users who only want some of them. Each plugin ships its full connector catalog as a .mcp.json.connectors-reference file with per-entry auth notes; users opt in via the plugin's connect skill.

If you contribute a plugin to this marketplace, please follow the same pattern.

Updating

If you see "/plugin isn't available in this environment" — you're in the standard Claude chat app (browser OR installed desktop app). The /plugin slash command is only supported in two environments: Claude Code (the developer CLI / IDE at claude.com/code, npm install -g @anthropic-ai/claude-code) and Anthropic Cowork. Everywhere else — claude.ai web chat, the Claude Desktop app, mobile — plugins are managed through the UI, not slash commands.

>

Plugins from this marketplace still install and run in those environments (skills auto-discover and work normally); only the /plugin management command is unavailable.

>

Fix: 1. In the chat UI — click the Plugins button at the bottom of the chat → Manage plugins → find the plugin → look for Update / Refresh / Remove. If there's no Update button, Remove then Add plugin → re-install from indranilbanerjee/neels-plugins. The re-pull fetches the latest version. 2. For slash-command management — switch to Claude Code (CLI or IDE) or Cowork. All three plugins run identically across every Anthropic surface; you're choosing where to type management commands.

>

The rest of this section assumes you're in Claude Code or Cowork.

There are two paths depending on whether you turned on auto-update during Quick Start step 4.

If auto-update is ON (recommended)

Claude Code refreshes the marketplace at startup and pulls the latest version automatically. After it fires, run /reload-plugins when prompted to pick up the new version mid-session.

If you prefer manual updates

/plugin marketplace update neels-plugins
/plugin uninstall <plugin-name>@neels-plugins
/plugin install <plugin-name>@neels-plugins
/reload-plugins

/plugin marketplace update only refreshes the catalog — it does not bump installed plugin versions. The uninstall + reinstall is what actually pulls the new version.

Force-reinstall (version unchanged but content changed)

Happens during fast-iteration debugging:

rm -rf ~/.claude/plugins/cache/neels-plugins
/plugin install <plugin-name>@neels-plugins
/reload-plugins

How to know when there's a new version

There is currently no in-product update notification for third-party marketplaces — no banner, no badge. Either:

• Watch this repo on GitHub (Releases) — you'll get an email when we tag a new version
• Check CHANGELOG.md in the individual plugin repos
• Or just run /plugin marketplace update neels-plugins periodically
