Deep Skills

Install

Up and running in one command

Two lines in Claude Code - the reference host. Using Codex, Cursor, or Copilot? Your host is right below.

/plugin marketplace add reurgency/marketplace
/plugin install deep-skills@reurgency

Update later with /plugin marketplace update reurgency.

Run your first /deep-plan How it works

Every host

One plugin, five ways in

The same six skills install natively on each host - no forks, no per-host rewrites. Full commands, the capability matrix, and per-host caveats live in the repo's HOSTS.md.

Host Skills Parallel fan-out Per-agent model Install
Claude Code ✓ ✓ ✓ /plugin marketplace add reurgency/marketplace → /plugin install deep-skills@reurgency
Codex ✓ ✓ ✓ codex plugin marketplace add reurgency/marketplace → /plugins → install 1
Cursor ✓ ✓ ✓ /add-plugin deep-skills (or Customize → Marketplace) 1
Copilot CLI ✓ gate 2 ✓ copilot plugin marketplace add reurgency/marketplace → copilot plugin install deep-skills@reurgency
Copilot / VS Code ✓ ⚠ sequential 2 ✓ file-based: set chat.agentSkillsLocations → plugins/deep-skills/skills (no marketplace)

1 Manifest authored; the empirical capability gate (install + run a full cycle, confirm fan-out + model binding) is pending. Fast-moving schema/command details are marked RE-VERIFY in HOSTS.md - check them against your host's current docs at install time.

2 VS Code Copilot's docs show only sequential handoffs. If the gate confirms no parallel fan-out, the single-agent skills (deep-plan, deep-implement, deep-docs) run fully, and the fleet skills (deep-code-review, deep-plan-review, deep-bugfix) route to a single-agent fallback on that host only.

Step by step

Pick your host

Copy-paste commands per host. Each one installs the identical skills - one shared source of truth, thin per-host manifests.

Codex

Codex

Codex reads the skills natively. Add the marketplace from your shell, then install inside Codex: /plugins → search “deep-skills” → Install.

Install from Agent chat - or through the Customize panel → Marketplace → install.

GitHub Copilot · CLI

Copilot CLI

Copilot CLI consumes the same marketplace directly. Verify afterwards with /skills list.

GitHub Copilot · VS Code editor

Copilot in VS Code

The VS Code editor has no skills marketplace - it's file-based. Point the chat.agentSkillsLocations setting at the repo's plugins/deep-skills/skills directory (preferred - no duplication), or copy/symlink the skill directories into .github/skills/.

No slash required

Plain English is the primary interface

Slash commands and flags are conveniences, not the way in. Every skill answers to natural language.

Just ask. “Make a deep plan for the export feature” invokes deep-plan exactly like typing /deep-plan - and “run a deep code review on this branch” invokes deep-code-review. On hosts without slash commands or CLI flags - Codex and Copilot chat among them - plain language isn't a fallback, it's the primary path. Say what you want at whatever rigor you want; the skill sorts out the rest.

Quickstart

Run your first /deep-plan

Five minutes from install to a plan a fresh agent could execute cold.

  1. Open your assistant in a real repo. Deep Skills plans against your actual codebase - its questions get sharp because it explores your code first.
  2. Describe the change you want. Type the command with your idea - or just say it in plain English.
    /deep-plan add rate limiting to the public API
  3. Answer only what the code can't. It explores first, then asks the few questions that remain - one at a time, in batches, or all at once. Steer it live; it always returns to where it left off.
  4. Collect the artifact. Your plan lands in your repo at .deep-skills/<effort-name>/01-Plan/plan.md - self-contained, resumable, ready to hand off.
  5. Keep the loop going. Hand the plan to deep-plan-review for independent critique, then deep-implement, deep-code-review, deep-bugfix, and deep-docs. See the whole loop →

Six skills, one pipeline

Each does exactly one job - run the whole chain or reach for any one on its own.
