**The most effective Claude plugin descriptions begin with a concise one-sentence purpose, list key capabilities and API integrations, include specific trigger phrases, define scope exclusions, and explicitly state privacy practices—following patterns proven in the `anthropics/claude-plugins-community` repository.**

Writing a compelling plugin description is not just marketing fluff—it directly impacts **discoverability**, **model triggering accuracy**, and **user trust**. In the `anthropics/claude-plugins-community` repository, the highest-quality plugins follow a consistent structural pattern that balances human readability with machine-friendly precision. This guide breaks down the seven best practices extracted from production-ready examples.

---

## Start with a Concise Purpose Statement

The first sentence of your description must communicate the plugin's core function without ambiguity. The **TRES Finance plugin** demonstrates this perfectly:

> "The first official TRES Finance plugin for Claude Code — blockchain accounting workflows, ledger management, and transaction analysis."

This single line in [`tres-finance-plugin/.claude-plugin/plugin.json`](https://github.com/anthropics/claude-plugins-community/blob/main/tres-finance-plugin/.claude-plugin/plugin.json) accomplishes three things: identifies the plugin category, names the specific domain (blockchain accounting), and hints at primary capabilities. Avoid front-loading with technical implementation details or lengthy setup instructions.

---

## List Key Capabilities and Primary APIs

After the purpose statement, enumerate the main actions your plugin enables. The **QuickDesign skill** in [`quickdesign/skills/quickdesign/SKILL.md`](https://github.com/anthropics/claude-plugins-community/blob/main/quickdesign/skills/quickdesign/SKILL.md) provides a model example:

```markdown
description: |
  Generate AI media — UGC promo videos, image edits, product creatives, video upscales — through Seedance, Kling, Sora2, Nano Banana, and GPT Image.

```

Note the pattern: **action verbs** (generate, edit, upscale) paired with **specific tool names**. This helps Claude's retrieval system match user intent to your plugin's actual functionality. Generic claims like "handles various media tasks" perform worse than explicit capability lists.

---

## Include Explicit Trigger Phrases

The most discoverable plugins document the exact utterances that should activate them. The `tres-upload-tx-header-validation` skill in [`tres-finance-plugin/skills/tres-upload-tx-header-validation/SKILL.md`](https://github.com/anthropics/claude-plugins-community/blob/main/tres-finance-plugin/skills/tres-upload-tx-header-validation/SKILL.md) implements this as a bulleted list within the description:

- "fix my CSV headers"
- "bulk transaction upload failed"
- "missing required columns"

```yaml

# Example: Skill description with trigger phrases

description: |
  Validate and repair CSV headers for TRES Finance transaction uploads.
  Trigger phrases: "fix my CSV headers", "bulk transaction upload failed", "missing required columns".

```

These phrases train Claude's relevance model to surface your plugin when users express related needs—even with varying wording.

---

## Define Scope and Exclusions Explicitly

Prevent accidental invocations by stating what your plugin **does not** do. The same TRES Finance CSV skill clarifies boundaries:

> "This skill does **not** handle contacts import or wallet uploads."

This exclusionary statement appears directly in [`tres-finance-plugin/skills/tres-upload-tx-header-validation/SKILL.md`](https://github.com/anthropics/claude-plugins-community/blob/main/tres-finance-plugin/skills/tres-upload-tx-header-validation/SKILL.md). Explicit negative scope reduces false-positive triggers and manages user expectations before they attempt unsupported operations.

---

## Reference Privacy and Telemetry Practices

User trust depends on transparent data handling. The repository's root [`README.md`](https://github.com/anthropics/claude-plugins-community/blob/main/README.md) establishes a standard:

```markdown
This plugin collects **no usage telemetry**.

```

For plugins requiring API keys or external services, disclose this explicitly. The **testdino plugin** in [`testdino/.claude-plugin/plugin.json`](https://github.com/anthropics/claude-plugins-community/blob/main/testdino/.claude-plugin/plugin.json) pairs minimal descriptions with clear configuration requirements:

```json
{
  "name": "testdino",
  "description": "Run TestDino-powered test analysis directly in Claude Code. No data leaves your environment.",
  "userConfig": [
    {
      "name": "TESTDINO_API_KEY",
      "description": "Your TestDino API key for test result analysis."
    }
  ]
}

```

---

## Use Plain Markdown Without Formatting Artifacts

The Claude marketplace renders descriptions as plain markdown. Avoid these common mistakes:

- **Backticks** for code terms (the renderer may display them literally)
- **HTML tags** (stripped or garbled in display)
- **Excessive markup** (bold, italics, headers within the description field)

Keep descriptions as simple text paragraphs or minimal bullet lists. The [`plugin.json`](https://github.com/anthropics/claude-plugins-community/blob/main/plugin.json) and [`SKILL.md`](https://github.com/anthropics/claude-plugins-community/blob/main/SKILL.md) files in the repository consistently follow this constraint.

---

## Respect Character Limits While Maintaining Completeness

Platform constraints typically enforce **200–300 character limits** for summary descriptions, with extended fields available for detailed capability lists. Structure your content hierarchically:

| Field | Purpose | Length Target |
|-------|---------|---------------|
| `description` (plugin.json) | One-sentence purpose | ~120 characters |
| `description` (SKILL.md) | Capabilities, triggers, exclusions | ~300 characters |

The **QuickDesign** example achieves this density without sacrificing clarity:

```markdown
description: |
  CLI for AI media generation: UGC videos, image edits, product creatives, upscales via Seedance, Kling, Sora2, Nano Banana, GPT Image.

```

---

## Complete Working Example

Combine all practices into a production-ready template:

```json
// plugin.json — top-level plugin description
{
  "name": "weather-lookup",
  "description": "Add real-time weather lookup to Claude Code using OpenWeather API. No telemetry collected.",
  "repository": "https://github.com/your-org/weather-lookup",
  "userConfig": [
    {
      "name": "OPENWEATHER_API_KEY",
      "description": "Your OpenWeather API key (obtain at https://openweathermap.org/api)"
    }
  ]
}

```

```markdown
<!-- skills/current-weather/SKILL.md — individual skill description -->
description: |
  Retrieve current weather conditions for any city worldwide.
  
  Trigger phrases: "what's the weather in [city]", "current temperature in [city]", "weather now in [city]".
  
  Capabilities: Temperature, humidity, wind speed, visibility, atmospheric pressure.
  
  Exclusions: Does not provide forecasts (use the `weather-forecast` skill), historical data, or severe weather alerts.

```

## Frequently Asked Questions

### What makes a Claude plugin description different from general software documentation?

Claude plugin descriptions serve dual audiences: human users browsing the marketplace and Claude's retrieval-augmented generation system selecting which skill to invoke. Unlike general documentation, they must include **trigger phrases** that match natural language queries and **scope exclusions** that prevent misfires. The `anthropics/claude-plugins-community` repository demonstrates that successful descriptions optimize for semantic search relevancy, not just readability.

### How long should a Claude plugin description be?

Aim for **120 characters** for the core `description` field in [`plugin.json`](https://github.com/anthropics/claude-plugins-community/blob/main/plugin.json) and **up to 300 characters** for skill-level descriptions in [`SKILL.md`](https://github.com/anthropics/claude-plugins-community/blob/main/SKILL.md) files. The TRES Finance and QuickDesign examples in the repository achieve completeness within these constraints by prioritizing action verbs, tool names, and trigger phrases over explanatory prose.

### Should I include API implementation details in the description?

No. Reserve technical implementation details for documentation or configuration schemas. The description should answer **what** the plugin enables and **when** to use it, not **how** it works internally. The QuickDesign skill mentions external APIs (Seedance, Kling, Sora2) only as capability indicators, not architectural documentation.

### Where exactly should trigger phrases appear in a Claude plugin?

Trigger phrases belong in the `description` field of **skill-level** [`SKILL.md`](https://github.com/anthropics/claude-plugins-community/blob/main/SKILL.md) files (located at `skills/{skill-name}/SKILL.md`), not in the top-level [`plugin.json`](https://github.com/anthropics/claude-plugins-community/blob/main/plugin.json). The [`tres-upload-tx-header-validation/SKILL.md`](https://github.com/anthropics/claude-plugins-community/blob/main/tres-upload-tx-header-validation/SKILL.md) file provides the canonical example, embedding phrases directly in the description text where Claude's relevance system can index them for matching.
