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.
🆕 July 7, 2026 — marketplace v3.16.0: Digital Marketing Pro v3.15.0, the Reliability & Truth release. A full-repo audit (orchestration / agents / skills / commands / scripts / docs-manifests) surfaced ~200 findings — all fixed in one coordinated pass, mirroring ContentForge's v3.16.0. One shared
_common.pyends the storage split-brain; a new doc-vs-argparse contract linter (check_skill_contracts.py) locks every skill invocation to real script flags; all 18 execution skills carry a uniform typed-approval gate +disable-model-invocation: false(closes issue #6); the Tessl review workflow moved to thetessl reviewCLI (closes issue #8); agents consolidated 25 → 24;embed-c2pa.pygained the EU AI Act Article 50--ai-disclosureassertion; connectors are honestly opt-in (fictional npm packages purged). DMP tests 123 → 207. 404 tests passing (DMP 207 + CF 143 + SF 54). 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.
| Your job-to-be-done | Install | What's in the box |
|---|---|---|
| Run end-to-end brand-strategy engagements across a portfolio (agencies, in-house, consultants) | digital-marketing-pro |
158 skills · 24 agents · 12-Part Strategy Flow · 6-platform AEO/GEO · EU AI Act Article 50 · Cowork-team-persistent · multi-brand · multi-jurisdiction compliance |
| Produce publish-ready long-form content (blog posts, white papers, case studies, executive briefs) | contentforge |
21 skills · 13 agents · 10 quality gates · 35-pattern AI humanizer · fact-checker · real .docx output · C2PA signing |
| Produce social media assets at agency scale (carousels, single-image posts, AI image / video creatives) | socialforge |
16 skills · 25 commands · asset-first compositing · AI image (Vertex AI Nano Banana Pro) · AI video (Kling v3.0 Pro) · C2PA signing |
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.
| If you're a... | Why this matters |
|---|---|
| 🏢 Marketing agency (50–200 brands) | One toolchain across every client, audit-trail compliance, new-hire onboarding from 6 weeks → 6 hours, Cowork team persistence so your senior strategists work in browser-based Cowork while your team Drive has every artifact. |
| 👔 In-house marketing team | Single canonical strategy document underwriting every campaign + content piece. No more "the deck and the blog post say different things." |
| 🚀 Marketing automation builder (n8n / Zapier / Make / Pipedream) | DMP's connector-resolver + executor pattern. 8 verified HTTP connectors execute end-to-end; 25 more return manifest-ready specs for OAuth-mediated platforms. |
| 💼 Solo consultant / freelance marketer | Per-engagement billing model: 50–60 canonical files for $15–40 of API spend in ~60 minutes. Installs on Codex / Cursor / Copilot CLI / Antigravity for terminal-native or IDE-native workflows. |
| 📈 Growth team / product marketer | Funnel architecture, attribution, MMM, incrementality testing, retention, churn — all anchored to the strategy document. |
| 🛡 Compliance-led marketer (EU · UK · India · Brazil · California) | EU AI Act Article 50, C2PA content provenance, deepfake disclosure, GDPR + CCPA + DPDPA + LGPD + 12 more jurisdictions baked into every output. |
DMP v3.14.1 → v3.15.0 + marketplace v3.15.0 → v3.16.0. (CF v3.16.0 and SF v1.13.1 unchanged.)
A full-repo audit (orchestration / agents / skills / commands / scripts / configs-docs-manifests) surfaced ~200 findings — all fixed in one coordinated pass, mirroring ContentForge's v3.16.0 the day before. DMP tests 123 → 207 (suite total 404):
- Storage split-brain fixed — one shared
_common.py(workspace_root/slugify_brand/ atomic writes /finish) adopted across the script layer; ends the four-different-slugifier bug that misfiled Cowork/Drive brand state. - Doc↔script contract linter — new
check_skill_contracts.pyparses every fenced script call in skills/commands/agents and validates actions/flags against each script's real argparse (0 mismatches, wired into CI). - Issue #6 closed — all 18 execution skills carry a uniform
## Execution gate(typed approval, cancel-on-anything, never-proceed-on-ambiguous input) +disable-model-invocation: falseso Codex's frontmatter validator stops erroring. - Issue #8 closed — Tessl review workflow moved from the retired
tesslio/skill-review@mainAction to thetessl reviewCLI +.github/tessl-rubric.yml. - EU AI Act Article 50 —
embed-c2pa.py --ai-disclosureembeds the C2PA 2.4c2pa.ai-disclosureassertion (applicable Aug 2, 2026). - Agents 25 → 24 —
competitor-intelligencemerged intocompetitive-intel(mode: snapshot|monitoring);memory-managerthinned to storage-only;intelligence-curatorowns intake/interpretation. - Connector honesty — the "13 connectors pre-configured" fiction removed (shipped
.mcp.jsonis empty), fictional npm packages purged, memory backends demoted to "only if you have a working server connected".
CF v3.15.3 → v3.16.0 + marketplace v3.14.1 → v3.15.0. (DMP v3.14.1 and SF v1.13.1 unchanged.)
The deepest ContentForge engineering pass since v3.0 — a five-layer audit (orchestration / agents / skills / scripts / configs) implemented end to end. CF tests 53 → 143 (suite total 320):
- Checkpoint/resume actually wired — every phase saves to a canonical run directory;
/contentforge:resumeworks for skill-started runs, honors mid-loop rework, reloads run metadata. - File-based phase handoff contract — agents read prior artifacts by path; full Pipeline Contract table (inputs → outputs → gate → loop target).
- Measured gates — new
text-metrics.pycomputes burstiness / FK grade / keyword placements; orchestrator verifies instead of trusting subagent self-reports. Density gate retired for placement checks. - GEO protection — Phase 6 structure manifest stops the humanizer from dismantling answer blocks; humanizer catalog 29 → 35 patterns with a defined AI-signal formula.
- EU AI Act Article 50 (applicable Aug 2, 2026) — AI-disclosure step in the publish path + per-platform AI-label fields; social specs add TikTok, Bluesky, YouTube Shorts.
- Script hardening — shared
_common.py(single slugifier fixes the Cowork sync-path bug, atomic writes, Windows UTF-8 guard, real exit codes); .docx gets image embedding + TOC + page footer. - Truth pass — honest "10 phases / 10 quality gates" claim, connector docs match the shipped empty
.mcp.json, ~50 broken slash references fixed, drift-locking release-consistency tests added.
DMP v3.14.0 → v3.14.1 + CF v3.15.2 → v3.15.3 + SF v1.13.0 → v1.13.1 + marketplace v3.14.0 → v3.14.1.
A second-pass cleanup after v3.14.0 caught two real classes of drift the release-consistency suite was not yet covering:
- Stale README section heading: DMP's
## Supported surfaces (vX.Y.Z)was still on v3.13.1 even though every manifest had been bumped to v3.14.0. CF/SF tests caught this kind of drift; DMP's didn't. - Stale "What's new" section in DMP README: the latest entry was v3.13.0; v3.13.1 and v3.14.0 had shipped without being added.
Fixed:
- DMP README — Cowork badge anchor + Supported-surfaces heading + 2nd
#supported-surfacesanchor + 3 new "What's new" entries (v3.14.1 + v3.14.0 + v3.13.1). - CF README — added v3.15.3, v3.15.2, v3.15.1 entries to Release notes.
- SF README — rewrote "Current Release" body with actual v1.13.0 content (heading had been renamed but body still described v1.12.0).
- Marketplace README — added v3.14.1 + v3.14.0 entries (this one).
- DMP
tests/test_release_consistency.pyextended to lock the## Supported surfaces (vX.Y.Z)heading to canonical version + verify all#supported-surfaces-v…anchor links match — closes the drift class permanently for DMP (CF/SF already had this).
Suite tests: 222 → 224 (+1 in DMP for new section-heading lock, +1 for anchor-sync lock).
DMP v3.13.1 → v3.14.0 + CF v3.15.1 → v3.15.2 + SF v1.12.1 → v1.13.0. Coordinated suite-wide refresh covering everything that shipped, broke, or got deprecated in the marketing-tech ecosystem since the last refresh on 2026-06-09. Every claim verified against primary vendor docs.
- Meta Graph API bumped v20.0 → v24.0 in DMP
scripts/connector_resolver.py(4 callsites). Pre-v24 calls scheduled to fail 2026-06-09. - Model registry rebuilt to 47 entries verified against Anthropic / OpenAI / Google primary docs. New active flagships: Claude Opus 4.8, GPT-5.5 family, gpt-image-2, Gemini 3.1 Pro Preview, Gemini 3.1 Flash-Lite, Veo 3.1 Preview, Nano Banana Pro/2 GA. Newly deprecated: full GPT-5 family + o3 family (shutdown 2026-12-11), Gemini 2.5 family (shutdown 2026-10-16), Imagen 4. Newly retired (auto-routed): Gemini 2.0 family (June 1), Gemini 3 preview image variants (June 25), Veo 2.0/3.0/3.0-Fast (June 30).
- Resolver hardened — now unconditionally rewrites
retiredmodel IDs toreplacement_id(was previously onlydeprecated). New test covers this. --check-paramsscanner flags unsafetemperature/top_p/top_knear Claude Opus 4.7+ targets (HTTP 400 risk).- 18 aliases re-pointed across all 3 plugins.
latest-text-anthropic→ claude-opus-4-8,latest-text-openai→ gpt-5.5,latest-video-google→ veo-3.1-generate-preview,latest-image-photoreal-google→ gemini-3-pro-image (Imagen 4 was deprecated path). - Google Ads API v24.1 + v24.2 sections added to DMP
skills/paid-advertising/google-ads.md— ADOPT_AI_MAX experiment type, mobile_device_platform segment, Local Services Ads viagoogle_local_services_info, GENERATE_LANDING_PAGE_TEXT, beta MultiPartyAuthReview. - EU AI Act Code of Practice second-draft refresh in DMP
skills/context-engine/eu-code-of-practice.md— Section 1 two-layered marking (C2PA satisfies metadata), Section 2 dropped AI-generated-vs-AI-assisted taxonomy, operational readiness checklist for 2026-08-02 applicability. - I/O 2026 additions to DMP
aeo-audit(Information Agents callout) +local-seo(Agentic Booking expansion to local services / home repair / beauty / pet care). - EvoLink vendor added to the model curator via community PR (multi-provider API gateway aggregating DeepSeek / Doubao / MiniMax via single API key).
- Suite-wide
docs/MODEL-CURATOR.mdrefresh with current aliases table + new § "Parameter compatibility — Claude Opus 4.7 and later".
Suite tests: 221 → 222 in this entry (DMP 115 + CF 53 + SF 54). Then v3.14.1 brought it to 224.
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-v182re-pointed at the live Current Release section
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
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.
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.
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.
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.
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.
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-performanceskill for the Google Search Console AI Performance Report rolled out 3 June 2026, plus a newskills/context-engine/eu-code-of-practice.mdreference doc for EU AI Act Article 50 transparency. Updates toaeo-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-disclosureassertion for Article 50 deployer compliance.
/plugin marketplace add indranilbanerjee/neels-plugins
In Cowork: Settings → Plugins → Add Marketplace → paste indranilbanerjee/neels-plugins.
/plugin list neels-plugins
/plugin install contentforge@neels-plugins
(Replace contentforge with digital-marketing-pro or socialforge as desired.)
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.
| Plugin | Version | What it does |
|---|---|---|
| digital-marketing-pro | 3.15.0 | The most comprehensive open-source AI marketing plugin — 158 skills, 24 specialist agents, 12-Part Strategy Flow producing the Four Core Documents, Two-Views Model, Decision Matrix, Living Project Instruction File.

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.

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.
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
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, andreplacement_idfor deprecated entries.resolve_model.py— resolver. Aliases likelatest-balanced-anthropic,latest-image-google,latest-video-wavespeedresolve to concrete ids at call time; deprecated ids passed via--modelauto-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.
- Create your plugin with a
.claude-plugin/plugin.jsonmanifest (include$schema,name,version,description,author,homepage,repository,license,keywords). - Push it to its own GitHub repository with a LICENSE file.
- Add an entry to
.claude-plugin/marketplace.jsonin this repo with thesource: { source: "github", repo: "owner/repo" }format. - Bump the marketplace
metadata.version(semver: minor bump for a new plugin or feature release in an existing plugin; patch for hotfixes). - Commit and push — the marketplace updates instantly.

All three plugins follow a strict "no global side-effects" pattern as of May 2026:
hooks/hooks.jsonships 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.jsonships 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-referencefile 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.
If you see "/plugin isn't available in this environment" — you're in the standard Claude chat app (browser OR installed desktop app). The
/pluginslash 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.aiweb 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
/pluginmanagement command is unavailable.Fix:
- 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.- 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.
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.
/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.
Happens during fast-iteration debugging:
rm -rf ~/.claude/plugins/cache/neels-plugins
/plugin install <plugin-name>@neels-plugins
/reload-plugins
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.mdin the individual plugin repos - Or just run
/plugin marketplace update neels-pluginsperiodically
