A red-team pass found four ways credential values still reached shareable artifacts after the initial redaction: - the remediation patch: a diff removing a hardcoded secret carries the raw value on its '-' lines by construction. harden now splits output: non-credential hunks in the shareable security_remediation.patch, credential hunks in a gitignored security_remediation.local.patch with comment-only placeholders in the shareable file - the other four agents had no secret-handling rules. legacy-analyst (hardcoded-config evidence in tech-debt findings), business-rules-extractor (credentials recorded as rule parameters), test-engineer (legacy literals becoming committed test fixtures), and architecture-critic (quoted code in notes files) now all mask values and cite file:line; assess's tech-debt prompt and ASSESSMENT.md masking now cover every section, not just Security Findings - non-git projects: a .gitignore protects nothing under SVN/Mercurial. Both commands now refuse --show-secrets without git and write the quarantine file to ~/.modernize/<system>/ outside the project tree - the patch-apply instruction was wrong in both documented layouts (symlinked legacy/ broke relative paths). Patches are now written with project-root-relative paths and applied from the project root Also: --show-secrets is now position-independent in both commands, and the README documents the full model.
Claude Code Plugins Directory
A curated directory of high-quality plugins for Claude Code.
⚠️ Important: Make sure you trust a plugin before installing, updating, or using it. Anthropic does not control what MCP servers, files, or other software are included in plugins and cannot verify that they will work as intended or that they won't change. See each plugin's homepage for more information.
Structure
/plugins- Internal plugins developed and maintained by Anthropic/external_plugins- Third-party plugins from partners and the community
Installation
Plugins can be installed directly from this marketplace via Claude Code's plugin system.
To install, run /plugin install {plugin-name}@claude-plugins-official
or browse for the plugin in /plugin > Discover

Internal Plugins
Internal plugins are developed by Anthropic team members. See /plugins/example-plugin for a reference implementation.
External Plugins
Third-party partners can submit plugins for inclusion in the marketplace. External plugins must meet quality and security standards for approval. To submit a new plugin, use the plugin directory submission form.
Plugin Structure
Each plugin follows a standard structure:
plugin-name/
├── .claude-plugin/
│ └── plugin.json # Plugin metadata (required)
├── .mcp.json # MCP server configuration (optional)
├── commands/ # Slash commands (optional)
├── agents/ # Agent definitions (optional)
├── skills/ # Skill definitions (optional)
└── README.md # Documentation
Skill-bundle plugins
When a plugin's source repository ships skills (SKILL.md files) without a .claude-plugin/plugin.json manifest, the marketplace entry can declare the skills directly using strict: false and an explicit skills array.
{
"name": "example-bundle",
"description": "Brief description of the bundled skills.",
"author": { "name": "Author Name" },
"category": "development",
"source": {
"source": "git-subdir",
"url": "https://github.com/example-org/sdk.git",
"path": "packages/agent-skills",
"ref": "main",
"sha": "<commit sha>"
},
"strict": false,
"skills": [
"./skill-a",
"./skill-b",
"./skill-c"
],
"homepage": "https://github.com/example-org/sdk"
}
Each path in skills is relative to source.path and points at a directory containing a SKILL.md. Paths can reach deeper than a single level — for example, ["./libA/skill-1", "./libB/skill-2"] exposes a curated subset across multiple library subdirectories. Each skill is registered as <plugin-name>:<skill-name> in Claude Code.
For the underlying schema, see Strict mode in the marketplace documentation.
