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 | $0.00019 | $0.00173 |
| Opus 5 | $0.00010 | $0.00086 |
| Sonnet 5 | $0.00004 | $0.00035 |
| Haiku 4.5 | $0.00002 | $0.00017 |
Grade A, and why
register-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 4d 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.
What it actually says
Register an Agent
Submit an A2A agent URL to Waggle for indexing and discovery.
Instructions
- Get the agent's base URL from the user (e.g.,
https://my-agent.example.com) - Use
mcp__waggle__registerto submit it - Report the registration result to the user
- Explain that the agent will be probed and indexed, and will appear in search once validated
Requirements
- The URL must serve an A2A agent card at
/.well-known/agent-card.jsonor/.well-known/agent.json - The agent must be publicly accessible
- Registration counts against the daily registration limit (10/day on free tier)
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.

register-agent is a skill published in the GitHub repository Waggle-AI/waggle-claude-code-plugin (0 stars, last pushed 6mo ago), licensed MIT. It adds 19 tokens to every session and 173 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 2026-08-31.
