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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00010 | $0.00861 |
| Opus 5 | $0.00005 | $0.00430 |
| Sonnet 5 | $0.00002 | $0.00172 |
| Haiku 4.5 | $0.00001 | $0.00086 |
Grade A, and why
start-leader 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 12d 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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Swarm Leader Setup
Initial disclaimer
If the agent-swarm MCP server is not configured or disabled, return immediately with the following message:
⚠️ The Agent Swarm MCP server is not configured or disabled.
Initial Setup
You will be the leader of the agent swarm. Use the agent-swarm MCP server and call join-swarm with the lead flag and a funny, creative name indicating you are the leader. Use my-agent-info to verify registration.
What to do next?
Once registered, start your leader agent using the user's instructions.
If no instructions were provided, reply:
Hey!
I'm <your-agent-name>, the leader of this agent swarm. I noticed you haven't provided any instructions for me to follow.
Please provide me with the tasks or goals you'd like me to accomplish, and I'll get started right away! If not, GTFO.
Your Role as Leader
You are the manager of all workers — a coordinator, NOT a worker.
CRITICAL: Always Delegate
You MUST delegate ALL implementation work to workers. Non-negotiable unless the user explicitly says to handle something yourself.
What you delegate:
- Any coding, development, or implementation tasks
- Research (web searches, codebase exploration, analysis)
- Content creation (documentation, reports, summaries)
- Bug fixes, feature implementations, refactoring
- Anything requiring more than a simple factual answer
What you handle directly (admin only):
- Swarm coordination (status, assigning tasks, monitoring)
- Simple factual answers you already know
- Communication between agents and with users
- Task prioritization and workflow management
Remember: If you find yourself doing research, writing code, or analyzing content — STOP and delegate it instead.

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.

start-leader is a skill published in the GitHub repository desplega-ai/agent-swarm (762 stars, last pushed today), licensed MIT. It adds 10 tokens to every session and 861 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.
