Peter537 Agent Plugin

Peter537 Agent Plugin is a portable Agent Plugins v1 package containing reusable skills for software research, planning, repository verification context, evidence-driven change verification, reader-first multilingual writing, source-comment health, evidence-driven bug diagnosis, behavior-preserving code simplification, codebase pruning, code and dependency audits, repository data-exposure reviews, supply-chain security, documentation, persistent product design-context authoring, UI design, and MAUI Blazor browser development. The complete GitHub edition also includes optional MCP integrations.

Included skills

Group	Skills
Planning & research	deep-planning, chatgpt-research
Engineering quality	deep-code-audit, diagnose-bugs, verification-context, verify-change, comment-health, prune-codebase, reduce-code-slop
Security & supply chain	audit-dependencies, audit-data-exposure
Documentation & writing	docs-audit, write-clearly
UI & .NET	ui-design-and-polish, maui-blazor-browser

See the skill catalog for each skill's purpose, package, and evaluation suite.

The skills/ and evals/ directories intentionally remain flat: every installable skill is an immediate skills/<slug>/ child, and every tracked evaluation suite mirrors it at evals/<slug>/. Logical categories come from skills.sh.json rather than filesystem nesting so Agent Plugin discovery remains compatible.

Included MCP servers

Server	Transport	Purpose
context7	Streamable HTTP	Retrieves current library documentation from Context7.
microsoft-learn	Streamable HTTP	Searches and reads public Microsoft Learn documentation.
playwright	stdio	Automates browser interactions with Playwright.
web-forager	stdio	Provides DuckDuckGo web and news search plus Jina Reader fetching.

Requirements and trust

• chatgpt-research requires ChatGPT Deep Research and signed-in in-app Browser control.
• audit-dependencies keeps explicit reviews read-only, does not execute dependency code or install scanners, and automatically researches only public package coordinates.
• diagnose-bugs keeps diagnostic evidence local and redacted, preserves existing work, and requires separate authorization for high-risk or external actions.
• verification-context is explicit-only, changes only a user-approved guidance artifact or separately authorized dependency-free thin wrapper, keeps private evidence local, and records commands and evidence states without treating authored context as execution proof.
• verify-change keeps source and acceptance criteria read-only, separates evidence layers, preserves existing work, and requires separate authorization for shared, remote, credentialed, or production environments.
• ui-design-and-polish creates or maintains persistent project design context only on direct request at an existing authoritative or explicitly approved path, keeps private repository evidence local, preserves source provenance and unresolved choices, and does not treat authored context as rendered or runtime proof.
• comment-health keeps source comments and native-tool evidence local, protects comments with legal, documentation, or machine semantics, and previews broad cleanup candidates before editing.
• prune-codebase treats analyzer results as candidates, preserves uncertain dynamic and external consumers, and previews broad removal candidates before editing.
• reduce-code-slop inspects source, tests, and existing verification output locally, preserves justified complexity, and does not install analyzers or dependencies.
• write-clearly keeps repository prose and author samples local by default, preserves protected meaning and format, and reports related findings outside the authorized edit scope without changing those files.
• playwright requires Node.js 18 or newer.
• web-forager requires uv and provisions a supported Python 3.10-3.13 runtime through uvx.
• The MCP servers use the network, and Playwright can interact with a browser. Review tool calls and third-party terms before use.
• If Node.js or uv is unavailable, the affected local MCP server may be disabled while the skills and other MCP servers remain usable.

Install the complete GitHub edition

The published v0.4.0 GitHub marketplace edition contains fifteen skills and all four MCP servers. The Codex CLI is not required.

1. In ChatGPT/Codex desktop, open Plugins, open the Add menu, and select Add plugin marketplace.
2. Enter Peter537/peter537-agent-plugin as the source.
3. Enter v0.4.0 as the Git ref.
4. Leave Sparse paths empty and add the marketplace.
5. Open Peter537 Plugins, install Peter537 Agent Plugin, and start a new task so its skills and MCP tools are loaded.

Install from Skills.sh

This route installs the skill directories in this repository. It does not install plugin.json, .codex-plugin/plugin.json, .agents/plugins/marketplace.json, mcp.json, or the four optional MCP servers.

List the available skills:

npx skills add Peter537/peter537-agent-plugin --list

Install one skill:

npx skills add Peter537/peter537-agent-plugin --skill deep-planning

Install every discovered skill:

npx skills add Peter537/peter537-agent-plugin --skill "*"

chatgpt-research still requires ChatGPT Deep Research and signed-in in-app Browser control; installing it through Skills.sh does not provide those capabilities.

Skills.sh availability is separate from repository compatibility and begins only after Skills.sh has observed a telemetry-enabled installation and refreshed its catalog.

Install from the OpenAI shared Plugins Directory

The public-directory edition is submitted separately from the GitHub release. Its v0.4.0 bundle contains all fifteen skills but does not include the four MCP servers; it becomes available only after OpenAI review and publication. Once available, search for Peter537 Agent Plugin in the shared Plugins Directory, open its details, and select the plus button to install it.

See the v0.4.0 public-submission document for listing copy, review scenarios, and the reproducible skills-only upload bundle.

Optional: Codex CLI

The Codex CLI is not required to install either desktop edition. Existing CLI users can instead add and install the GitHub marketplace with:

codex plugin marketplace add Peter537/peter537-agent-plugin --ref v0.4.0
codex plugin add peter537-agent-plugin@peter537

Start a new Codex CLI session after installation so the plugin components are loaded.

Other Agent Plugins clients

Clone or download this repository and follow the installation workflow provided by your client. Conformant clients discover the root plugin.json, skills under skills/, and MCP servers in mcp.json; component and transport support can vary, so consult the compatible clients list.
