Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00016 | $0.01487 |
| Opus 5 | $0.00008 | $0.00744 |
| Sonnet 5 | $0.00003 | $0.00297 |
| Haiku 4.5 | $0.00002 | $0.00149 |
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 — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 " → 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 ofsimple(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:
- Role: What is this agent's primary role?
- Expertise: What domains or technologies does it specialize in?
- Responsibilities: What are its 3-5 key responsibilities?
- Tools needed: Which tools does it require? (Read, Write, Bash, Grep, WebFetch, Task)
- Model tier: haiku (fast/utility), sonnet (balanced), opus (reasoning-heavy)
- Output format: What structured output should it produce?
What this file has done since we first saw it
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.

add-agent is a skill published in the GitHub repository jmagly/aiwg (209 stars, last pushed today), licensed MIT. It adds 16 tokens to every session and 1,487 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
