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 | $0.00053 | $0.02882 |
| Opus 5 | $0.00026 | $0.01441 |
| Sonnet 5 | $0.00011 | $0.00576 |
| Haiku 4.5 | $0.00005 | $0.00288 |
Grade C, and why
agent-identity scanned grade C with 2 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 8d 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.

How it starts
The opening of the file, as written. The whole thing — 312 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Identity (AID) Protocol
Authenticate AI agents with auth servers using cryptographic identity documents and proof of possession. AID is self-contained — no other protocols required.
When to use this skill
Use this skill when the user or task requires:
- Initializing an agent's Ed25519 identity
- Requesting registration with an auth server (agent-initiated)
- Registering an agent's identity with an auth server (admin-initiated)
- Checking the status of a pending registration request
- Obtaining JWT tokens for API access via token exchange
- Checking an agent's AID registration status
- Setting up agent-to-server authentication
- Configuring scoped permissions for agent API access
Quick Start
# 1. Initialize agent identity (one-time)
aid-init.sh --auto
# 2a. Request registration (agent-initiated, no admin token needed)
aid-request.sh --auth https://auth.23blocks.com/acme
# ... wait for admin approval ...
aid-request.sh --auth https://auth.23blocks.com/acme --poll
# 2b. Or: admin-initiated registration (requires admin token)
aid-register.sh --auth https://auth.23blocks.com/acme \
--token <ADMIN_JWT> --role-id 2
# 3. Get a JWT token
TOKEN=$(aid-token.sh --auth https://auth.23blocks.com/acme --quiet)
# 4. Use it for API calls
curl -H "Authorization: Bearer $TOKEN" https://api.example.com/resource

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.

agent-identity is a skill published in the GitHub repository 23blocks-OS/ai-maestro-plugins (9 stars, last pushed 3d ago), licensed MIT. It adds 53 tokens to every session and 2,882 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
