add-agent

add-agent is a skill for Claude Code from k9aif/k9-aif-framework. It costs 36 tokens per session (1,189 once invoked), scanned A, original, Apache-2.0.

A scaffolding command for adding a new agent to the K9-AIF framework, a system for building governed AI agents. Given an agent name and app name, it prepares the agent's YAML configuration, Python class, squad registration stub, and test stub.

In plain words
What is it for?
Use it when starting a new K9-AIF agent inside an existing application, so the agent has configuration, code, registration, and test placeholders.
Why use it?
It creates the expected starter files and checks that the K9-AIF project has been configured before making changes. It also asks for confirmation when the named app folder does not exist.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

add-agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Before doing anything else, check that /k9aif:configure has been run. If K9AIF_PROJECT_ROOT and K9AIF_APP_NAME are not set, refuse and say:

"Please run /k9aif:configure first to set your project root and app name." Do not proceed until init has been run.

K9-AIF: Add Agent

Scaffold a complete new agent for the K9-AIF framework. The user provides: <AgentName> <AppName> (e.g. ClaimsTriageAgent MyApp).

Before creating any files:

  1. Check whether examples/<AppName>/ already exists.
  2. If it does NOT exist, ask the user to confirm before proceeding:

    "The app folder examples/<AppName>/ does not exist yet. Do you want to create a new app structure, or did you mean a different app name? Existing apps: (list folders under examples/)"

  3. Only proceed once the user confirms the app name.

What to create

1. Agent YAML — examples/<AppName>/agents/yaml/<agent_name_lower>.yaml

name: <AgentName>
class: <AgentName>

description: >
  <one paragraph — what this agent does>

pattern: reasoning
model: reasoning

role: >
  You are a ...

goal: >
  Your goal is to ...

instructions:
  - Instruction one
  - Instruction two

output_schema:
  result: string
  confidence: float

governance:
  pre_process: true
  post_process: false

2. Python class — examples/<AppName>/agents/src/<agent_name_lower>.py

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
