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 | $0.00000 | $0.00405 |
| Opus 5 | $0.00000 | $0.00202 |
| Sonnet 5 | $0.00000 | $0.00081 |
| Haiku 4.5 | $0.00000 | $0.00040 |
Grade A, and why
amp-identity scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
/amp-identity
Quick identity check for context recovery. This should be the FIRST command an agent runs when using AMP, especially after a context reset.
Usage
/amp-identity [options]
Options
--json, -j- Output as JSON--brief, -b- One-line summary
What It Shows
- Agent name and address
- Tenant/organization
- Public key fingerprint
- Initialization status
Examples
Check identity (human-readable)
/amp-identity
Get JSON output
/amp-identity --json
One-line summary
/amp-identity --brief
Implementation
When this command is invoked, execute:
scripts/amp-identity.sh "$@"
Output
Human-readable:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
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.

amp-identity is a command published in the GitHub repository agentmessaging/claude-plugin (5 stars, last pushed 14d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 405 tokens. 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.
