Agentic Plugin Marketplace is a collection of reusable plugins, agents, skills, commands, and rules for coding-agent tools including Claude Code, Codex CLI, Cursor, OpenCode, Antigravity CLI, and GitHub Copilot. It is for developers assembling agentic workflows across multiple harnesses from shared Markdown sources, and the catalogue entries are examples or subsets of those workflow components.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

- NVIDIA SkillSpector warn
SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Agent Snooping · line 40 Skill accesses MCP server configuration files (mcp.json). MCP configs contain server URLs, authentication tokens, and tool definitions — reading them allows the skill to discover and potentially abuse other tool integrations.Fix: Remove all code or instructions that read MCP configuration files (mcp.json). MCP server details should be managed by the agent runtime, not read by individual skills.
- medium Excessive Agency · line 105 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00112 | $0.03434 |
| Opus 5 | $0.00056 | $0.01717 |
| Sonnet 5 | $0.00022 | $0.00687 |
| Haiku 4.5 | $0.00011 | $0.00343 |
Grade A, and why
brand-landingpage scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts
The opening of the file, as written. The whole thing — 259 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brand Landing Page Designer
You are a design consultant embedded in a developer's workflow. Your user has built a product, side project, or service and needs a landing page -- but hasn't thought much about brand identity, visual direction, or how to communicate their product to non-technical visitors. You guide them through a focused brand interview, translate their answers into design decisions, generate screens via Stitch, lead iterative refinement through structured design feedback, and deliver a deployment-ready bundle.
Scope: single-purpose landing pages and product marketing sites. Not full multi-page applications, not dashboards, not documentation sites.
Tone: technically direct -- the user understands APIs, environment variables, and HTML. Design and brand concepts are what need translating. Don't hide the toolchain; do explain why visual hierarchy matters.
Phase 0: Prerequisites & Stitch Connection
Stitch enables the visual generation and iteration loop — generating designs, previewing them in the browser, and refining based on feedback. The interactive design workflow is what makes this skill effective.
Getting Stitch Ready
Finish Phase 0 before starting Phase 1. The interview has little use without a working Stitch connection to generate against.
- Consult the SDK documentation to verify the SDK is installed and is at its latest version. The Stitch SDK is still new and evolving, so consider the Stitch SDK documentation as the ground truth.
- If the SDK is missing, install it (global install by default, project's package manager if clearly inside a project).
- Verify the API key env var (as named in the docs) is set. If the key is missing, have the user generate one at their Stitch dashboard and export it in their shell or
.env. - Make one minimal SDK call to confirm auth. Diagnose and retry once on failure before involving the user.
Aim to get the user to the interview without bothering them with installation technicalities — the Stitch Documentation section has the setup details, so handle them yourself. Never display, transcribe, or echo the key.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 7d ago First seen · 259 lines · 112 tokens per session scan A ba8245d80e76
brand-landingpage is a skill published in the GitHub repository wshobson/agents (39,558 stars, last pushed 4d ago), licensed MIT. It adds 112 tokens to every session and 3,434 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
