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

amp-identity 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 1mo 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.

Implementation

When this command is invoked, execute:

AMP Identity

  Name:        backend-api
  Tenant:      23blocks
  Address:     [email protected]
  Fingerprint: a1b2c3d4e5f6...

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Brief:

AMP: [email protected] (a1b2c3d4e5f6...)

JSON:

{
  "initialized": true,
  "name": "backend-api",
  "tenant": "23blocks",
  "address": "[email protected]",
  "fingerprint": "a1b2c3d4e5f6..."
}

When to Use

  • First thing after context reset — rediscover who you are
  • Before sending messages — verify your identity is correct
  • Debugging — confirm AMP is initialized and keys exist

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.
