Tomstack

Tom Tang's canonical collection of reusable agent skills, plus the public marketplace for standalone agent tools.

Skills are maintained together here so invocation metadata, documentation, release versions, and install paths do not drift one repository at a time. Standalone products keep their own repositories when they have a CLI, runtime, MCP server, or independent release lifecycle.

Install the skills

Claude Code managed bundle

claude plugin marketplace add tombelieber/tomstack
claude plugin install tomstack-skills@tomstack

The plugin is a managed, read-only bundle of every promoted skill.

Codex and other agents

npx skills@latest add tombelieber/tomstack

Choose the skills and target agents you want. Installing both the Claude bundle and copied Claude skills creates duplicates, so use one Claude route.

Install or update one skill:

npx skills@latest add tombelieber/tomstack --skill=<name>
npx skills@latest update <name>

Skills

Engineering

User-invoked

• auto-pilot: Deliver an approved plan through a verified PR and an explicitly authorized release boundary.

Model-invoked

• impact-aware-qa: Choose the smallest sufficient repository verification without losing correctness.

Productivity

User-invoked

• first-principles-xy-problems: Deep, design-only problem discovery before choosing a solution.

Model-invoked

• backup: Manage and restore Claude Code backups.
• chatgpt-share-dump: Archive ChatGPT share links into agent-readable context.
• cleanup: Find and clean orphaned development processes safely.
• pain-point-mining: Turn real interaction history into ranked product pain points and requirements.

Draft, retained, and retired skills live in skills/in-progress, skills/misc, and skills/deprecated; they are not shipped in the managed plugin.

Source map and compatibility boundaries

Standalone tools marketplace

These products retain independent repositories and releases because they ship more than a skill:

Product	Distribution	Purpose
codex-auto-pilot	Codex marketplace, GitHub	Verified PR and release execution
claude-backup	Claude marketplace, npm	Claude Code backup and restore CLI
chatgpt-share-dump	Claude marketplace, GitHub	ChatGPT share archive CLI
pain-point-mining-agent	Claude marketplace, GitHub	Product-signal mining workflow
orphan-reaper	Claude marketplace, npm	Orphan development-process cleanup CLI

Install individual plugins from the same marketplace when you need their bundled executable or hooks:

claude plugin install orphan-reaper@tomstack
claude plugin install claude-backup@tomstack
claude plugin install chatgpt-share-dump@tomstack
claude plugin install pain-point-mining-agent@tomstack

Maintainer workflow

npm install
npm run check
claude plugin validate . --strict

Add new work under skills/in-progress. Promotion into engineering or productivity requires root and bucket README entries, a human-facing docs page, agents/openai.yaml, and an explicit Claude plugin manifest path.

For local development, scripts/link-skills.sh links repository skills into ~/.claude/skills and the Agent Skills-compatible ~/.agents/skills root. It refuses to replace existing directories unless --replace is provided, in which case it moves them to timestamped backups first.
