AI Agent Skills

A skill collection that enables collaborative development with a team of specialized AI agents.

Features

• 90 Global Agents + 3 Project-local Extensions - Broad reusable coverage without exposing repository-specific operating skills everywhere
• Nexus Orchestrator - Analyzes tasks and automatically designs optimal agent chains
• Platform Agnostic - Works with Claude Code, Codex CLI, Antigravity CLI, and others

Quick Start

Installation

Recommended — one working tree, symlinked into every CLI

git clone https://github.com/simota/agent-skills.git ~/repos/agent-skills
cd ~/repos/agent-skills
make link

make link symlinks each skill directory into ~/.claude/skills, ~/.agents/skills, and ~/.gemini/antigravity-cli/skills individually, so every CLI reads the same working tree and a single git pull updates all of them. Skills already present in those directories are preserved: a name that already exists is reported and skipped, never overwritten. Missing destination parents are skipped except for the guarded Codex migration described below, so the same command works on a single-CLI machine. A directory is an installation hint, not a live CLI availability test.

Command	Effect
make link	Link into all three CLI directories — link-claude / link-codex / link-agy for just one
make status	Show the link count per CLI (linked / linkable) and how many entries each directory holds
make unlink	Remove only links created by make link; other skills and custom aliases stay in place

Alternative — clone straight into a CLI directory

# For Claude Code
git clone https://github.com/simota/agent-skills.git ~/.claude/skills

# For other platforms
git clone https://github.com/simota/agent-skills.git /path/to/your/skills

The shortest path when the target directory does not exist yet and only one CLI needs the skills.

Usage

/Nexus I want to implement a login feature
/Scout Investigate the cause of this bug
/Radar Improve test coverage
/Vision I want to redesign the dashboard with a modern look

Runtime compatibility and legacy Codex installs

Current model/CLI facts and official sources live in _common/CLI_COMPATIBILITY.md. Skills remain model-agnostic; actual availability, permissions and loading require runtime verification. Gemini CLI and Cursor are secondary readers, not additional installer targets.

Codex skills now use ~/.agents/skills; settings still use ~/.codex. The installer preserves old files. To remove only this repository's old links, run make unlink-codex CODEX_DIR="$HOME/.codex/skills", inspect the result, then make link-codex. Foreign files/links are not removed. If .agents is absent but .codex exists, the installer creates the new parent only outside the source repository; otherwise create the intended external skill root explicitly.

Overview

This repository contains 90 globally reusable AI agents and 3 repository-local operating extensions. Each skill specializes in a specific domain and is coordinated by the Nexus orchestrator when available in the active profile.

Roster Counting

• 90 global skills are the active, reusable roster under <skill-name>/SKILL.md.
• 3 project-local extensions (orbit, lore, and darwin) are repository operating skills and are not included in the global count or global profiles.
• .claude/skills/ is the canonical project-local location; .agents/skills/ is a cross-tool mirror, not an additional set of skills.
• .archive/ holds a retired skill only while prune's sunset protocol keeps it, and is excluded from every active-roster count. It is currently empty; earlier retired packages are recoverable from git history.

The active repository surface is therefore 90 global + 3 project-local = 93 distinct skills.

Workflows

Basic Usage

1. Invoke an agent with /AgentName
2. The agent executes the task
3. Suggests handoff to other agents as needed

Orchestration with Nexus

Use Nexus for complex tasks. Nexus operates in the following modes:

Mode	Trigger	Behavior	Interaction
Full Auto (default)	no marker, or ## NEXUS_AUTORUN_FULL	Executes all tasks, including COMPLEX, with guardrails	Ask First triggers and guardrail escalations only
Auto	## NEXUS_AUTORUN	Executes simple tasks only; complex tasks fall back to Guided	Ask First triggers, guardrail escalations, and errors
Guided	## NEXUS_GUIDED	Confirms at decision points	Option-based interaction
Interactive	## NEXUS_INTERACTIVE	Confirms at each step	Always interactive
Continue	## NEXUS_HANDOFF	Result handoff	Interaction as needed

Interactive Execution (Guided/Interactive)

Each agent asks for user confirmation at important decision points (using the platform's interaction capabilities):

• Start confirmation (Interactive only): Confirms approach after chain design, before execution — Guided confirms only at decision points
• Decision point confirmation: Security risks, destructive changes, multiple approaches, etc.
• Questions as options: Choose from 2-4 options ("Other" is always available)

# Example option-based question
questions:
  - question: "A potential security vulnerability was found. How would you like to proceed?"
    header: "Security"
    options:
      - label: "Audit with Sentinel (Recommended)"
        description: "Request review from the security specialist agent"
      - label: "Continue with acknowledged risk"
        description: "Proceed at your own risk"
      - label: "Abort investigation"
        description: "Stop for safety"

Automatic Mode Selection by Complexity

Indicator	SIMPLE	COMPLEX
Estimated steps	1-2	6+ (3-5 = MEDIUM)
Affected files	1-3	4+
Security-related	No	Yes
Destructive changes	No	Yes

• Default (AUTORUN_FULL): Executes all tasks, including COMPLEX, with guardrails
• SIMPLE + NEXUS_AUTORUN: Fully automatic execution
• COMPLEX under NEXUS_AUTORUN: Switches to Guided mode (interaction required)

See _common/INTERACTION.md for details.

Chain Templates by Task Type

Source of truth: base chains (rows without a /variant) come from nexus/reference/routing-matrix.md; TYPE/variant rows come from nexus/reference/agent-chains.md. This is a representative excerpt — where it differs, those files win. Variant rows omit the terminal Guardian (SHIP) step that the matrix default adds for code changes; ? marks an optional step.

Parallel Execution (Rally Integration)

For large-scale tasks where parallel execution is beneficial, Nexus escalates to Rally (agent-chains.md § Rally Parallel Chain Variants).

Base Chain	Parallel Chain
FEATURE/L	Spark > Sherpa > Rally(Forge+Artisan, Builder, Radar)
FEATURE/M (multi-unit)	Sherpa > Rally(Builder x N, Radar)
FEATURE/fullstack	Rally(Artisan, Builder, Radar)
BUG/multiple	Rally(Builder x N) > Radar
REFACTOR/arch (multi-module)	Atlas > Sherpa > Rally(Zen x N) > Radar
SECURITY/full	Rally(Sentinel, Probe) > Builder > Radar
TEST/coverage	Rally(Radar, Voyager)
MODERNIZE/stack	Lens > Shift (detect+modernize) > Sherpa > Rally(Builder x N) > Radar
DOCS/full	Rally(Quill, Canvas, Vitrine)

Rally Escalation Criteria: Rally is triggered when there are 2+ independent implementation steps, changes span 4+ files across 2+ domains, or Sherpa detects a parallel_group.

Nexus parallel vs Rally: Nexus's built-in _PARALLEL_BRANCHES is for lightweight parallelism (each branch < 50 lines). Rally's multi-session parallelism is used for substantial implementation work.

Nexus build modes: feature handles one bounded capability, deliver sizes a product/MVP chain to scope, and apex runs a high-investment discovery-to-ship workflow.

Shared Knowledge

Agents share knowledge through the .agents/ directory:

File	Purpose	When to Update
PROJECT.md	Shared knowledge + activity log	When the task produced a reusable insight or a decision later agents need (_common/OPERATIONAL.md § Activity Log)
{agent}.md	Agent-specific learnings	When domain-specific discoveries are made

PROJECT.md Structure

• Architecture Decisions - Record of architecture choices
• Domain Glossary - Unified terminology
• API & External Services - External service constraints
• Known Gotchas - Known pitfalls
• Security Considerations - Security constraints
• Performance Budgets - Performance targets
• Activity Log - Agent work history

Agent Principles

Shared rules live in _common/ (BOUNDARIES.md, OPERATIONAL.md, INTERACTION.md, ...); each skill's ## Boundaries section states its own Always / Ask first / Never rules.

Boundary Types

Marker	Meaning
Always do	Must always be done
Ask first	Requires confirmation
Never do	Must never be done

Usage Examples

Multi-Agent Collaboration (Nexus)

New Feature Development (Auto-execution)

/Nexus
I want to add a user profile editing feature
- Edit name, email, and avatar image
- With validation
- Show toast on successful save

## NEXUS_AUTORUN_FULL

Execution chain: Spark (spec) > Sherpa (task decomposition) > Forge (prototype) > Builder (production implementation) > Radar (tests) > Quill (documentation)

---

Bug Fix (Complex Case)

/Nexus
Investigate and fix a payment error that only occurs in production.
It doesn't reproduce locally.

## NEXUS_AUTORUN_FULL

Execution chain: Scout (investigation) > Sherpa (task decomposition) > Builder (fix) > Radar (regression tests) > Sentinel (security verification)

---

Large-scale Refactoring

/Nexus
The authentication module has become spaghetti code.
I want to refactor it to follow Clean Architecture.

Execution chain: Atlas (architecture design) > Sherpa (phased plan) > Zen (refactoring) > Radar (tests)

---

UI Feature Addition

/Nexus
Add a review submission feature to the product detail page.
I want users to be able to input star ratings and comments.

Execution chain: Spark (spec) > Forge (UI prototype) > Muse (design adjustment) > Builder (implementation) > Radar (tests)

---

Step-by-Step Execution (Manual Control)

Gradual Feature Development

/Nexus
I want to add a search feature.

## NEXUS_INTERACTIVE

## NEXUS_INTERACTIVE confirms before every step; /Nexus with no marker runs as AUTORUN_FULL.

AUTORUN Mode (Automatic Execution - Recommended)

## NEXUS_AUTORUN_FULL
I want to add a search feature.

Nexus automatically executes the chain:

## Nexus Execution: Add search feature
- Chain: **Spark** > **Sherpa** > **Builder** > **Radar**
- Mode: AUTORUN_FULL

### Executing Step 1/4: Spark
_AGENT_CONTEXT:
  Role: Spark
  Task: Create search feature specification

[Creating specification as Spark...]

_STEP_COMPLETE:
  Agent: Spark
  Status: SUCCESS
  Next: Sherpa

### Executing Step 2/4: Sherpa
[Automatically proceeding to next step...]

No copy-paste needed - automatically executes to the final deliverable.

GUIDED Mode (Confirm at Decision Points)

Nexus runs the chain itself and pauses only at decision points (Ask First triggers, guardrail escalations, or a skill's interaction triggers). Use ## NEXUS_INTERACTIVE to confirm every step instead:

## NEXUS_GUIDED
I want to add a search feature.

Nexus designs the chain, runs it, and stops when a decision needs you:

## Nexus Plan: Add search feature
- Chain: **Spark** > **Sherpa** > **Builder** > **Radar**
- Current step: 1/4 (Spark)

### Decision needed
Spark proposed two search scopes. Which should Sherpa plan for?
[Options]

Task Decomposition in Practice (Sherpa)

Breaking Large Tasks into Small Steps

/Sherpa
I want to implement an e-commerce checkout flow.

Output:

## Sherpa's Guide
**Current Objective:** Checkout flow implementation
**Progress:** 0/8 steps completed

### NOW: Create type definitions for cart contents
Define CartItem and CartSummary interfaces.
*(Shall I invoke Builder?)*

### Upcoming Path:
- [ ] Create cart API endpoint
- [ ] Shipping address input form
- [ ] Payment method selection UI
- [ ] Order confirmation screen
- [ ] Order completion processing
- [ ] Error handling
- [ ] Add tests

**Status:** On Track

Customization

Adding New Agents

Follow CONTRIBUTING.md § 新しいグローバルエージェントの追加 (adding a new global agent): it lists the required sections, the Complexity Budget declaration, every roster that must be updated by hand, and the generators to re-run. A new skill is done when make check passes.

Modifying Agents

Edit each SKILL.md directly, following _templates/SKILL_TEMPLATE.md. Frontmatter example:

---
name: skill-name
description: Agent description
