How it fires

  • Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

Add Agent

Scaffold a new agent definition file inside an existing addon or framework.

Triggers

Alternate expressions and non-obvious activations (primary phrases are matched automatically from the skill description):

  • "I need a new agent" → scaffold agent in specified target
  • "build me an agent" → scaffold agent with interactive guidance
  • "write an agent for X" → scaffold agent named after the described role
  • "agent for <role>" → derive name from role, prompt for target

Trigger Patterns Reference

| Pattern | Example | Action | |---------|---------|--------| | Named add | "add agent security-auditor --to sdlc-complete" | Scaffold directly | | Role description | "create an agent that reviews PRs" | Derive name, scaffold | | Interactive | "add agent --interactive" | Guided mode, ask for name/target/template | | Target omitted | "add agent code-reviewer" | Ask which addon or framework |

Process

1. Parse Arguments

Extract from `$ARGUMENTS`:

  • `<name>` — kebab-case agent name (required)
  • `--to <target>` — addon or framework directory name (required)
  • `--template <type>` — one of `simple` (default), `complex`, `orchestrator`, `validator`
  • `--interactive` — enable guided design questions

If either `<name>` or `--to` is missing, ask before proceeding.

2. Validate Target

Confirm the target addon or framework exists:

# Check addons
ls agentic/code/addons/<target>/

# Check frameworks
ls agentic/code/frameworks/<target>/

If not found, report available targets and stop.

3. Interactive Design (if --interactive)

Ask the following before generating:

1. **Role**: What is this agent's primary role? 2. **Expertise**: What domains or technologies does it specialize in? 3. **Responsibilities**: What are its 3-5 key responsibilities? 4. **Tools needed**: Which tools does it require? (Read, Write, Bash, Grep, WebFetch, Task) 5. **Model tier**: haiku (fast/utility), sonnet (balanced), opus (reasoning-heavy) 6. **Output format**: What structured output should it produce?

4. Select Template

| Template | Use When | Default Model | Tools | |----------|----------|---------------|-------| | `simple` | Single-purpose utility agent | haiku | Read, Write | | `complex` | Domain expert, reviewer, analyst | sonnet | Read, Write, Grep | | `orchestrator` | Coordinates other agents | opus | Task | | `validator` | Read-only quality/compliance gate | haiku | Read, Grep |

5. Run Scaffolding

aiwg add-agent <name> --to <target> --template <type>

This generates `<target>/agents/<name>.md` with the appropriate frontmatter and section stubs.

6. Customize the Generated File

The generated agent file requires population of these sections:

---
name: <name>
description: <one-sentence purpose>
model: <claude-haiku-4-5|claude-sonnet-4-6|claude-opus-4-7>  # Pin specific variant; bare aliases (`sonnet`) inherit the parent session's 1M-context attributes and hit the usage-credit gate on subagent dispatch. See #1442.
tools: <comma-separated tool list>
category: <phase or domain>
---

# Agent Title

[Role description]

## Expertise

[Domain knowledge and skills]

## Responsibilities

[Numbered list of what this agent does]

## Workflow

[How it approaches tasks — research, draft, validate, output]

## Output Format

[Expected structure of deliverables]

7. Validate Against 10 Golden Rules

After creation, run the agent linter:

aiwg lint agents <target>/agents/<name>.md --verbose

Key checks:

  • Single responsibility (no "and" overload in description)
  • Minimal tools (0-3 tools, each justified)
  • Explicit I/O contract defined
  • Model tier matches task complexity

8. Update Manifest

The CLI tool updates `<target>/manifest.json` automatically. Verify:

{
  "agents": ["existing-agent", "<name>"]
}

Generated Structure

<target>/agents/<name>.md

Manifest updated: `<target>/manifest.json`

Output Format

Agent Created: <name>
─────────────────────
Location: <target>/agents/<name>.md
Template:  <type>
Model:     <model>

Created:
  ✓ <target>/agents/<name>.md
  ✓ manifest.json updated

Validation:
  ✓ Single responsibility
  ✓ Tool count within limit
  ✓ I/O contract defined

Next Steps:
  1. Edit Expertise section with domain knowledge
  2. Define Responsibilities (3-5 items)
  3. Specify Output Format structure
  4. Run: aiwg lint agents <target>/agents/<name>.md

Examples

Example 1: Simple utility agent

**User**: "add agent dependency-auditor --to aiwg-utils"

**Action**:

aiwg add-agent dependency-auditor --to aiwg-utils

**Result**: `agentic/code/addons/aiwg-utils/agents/dependency-auditor.md` scaffolded with simple template (haiku, Read + Grep tools).

Example 2: Complex domain expert

**User**: "create a threat modeling agent for sdlc-complete"

**Extraction**: name=`threat-modeler`, target=`sdlc-complete`, template=`complex`

**Action**:

aiwg add-agent threat-modeler --to sdlc-complete --template complex

**Result**: `agentic/code/frameworks/sdlc-complete/agents/threat-modeler.md` scaffolded with sonnet model, Read/Write/Grep tools.

Example 3: Interactive guided creation

**User**: "add agent --interactive --to sdlc-complete"

**Process**: Guided questions gather role, expertise, responsibilities, tools, and model tier before scaffolding.
