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.
