test-secret

A command that checks whether a value would be identified as a secret, such as an API key, access key, national ID number, or card number.

In plain words
What is it for?
Use it to test secret-detection rules, view the detected type and confidence, and see which filtering approach would apply.
Why use it?
It helps explain why a value might be blocked or hidden and lets you check a value before adding an exception.

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

test-secret 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 yesterday.

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.

NAME
    test-secret - Test if a value would be detected as a secret

SYNOPSIS
    /memory:test-secret <value>

DESCRIPTION
    Test if a given value would be detected as a secret by the filtering system.
    Shows the detection type, confidence score, and what filtering strategy would apply.

    This is useful for:
    - Verifying detection rules work correctly
    - Understanding why content was blocked/redacted
    - Testing before adding to allowlist

OPTIONS
    --help, -h            Show this help message

EXAMPLES
    /memory:test-secret "AKIAIOSFODNN7EXAMPLE"
        Test if this looks like an AWS access key

    /memory:test-secret "123-45-6789"
        Test if this looks like a US SSN

    /memory:test-secret "4111111111111111"
        Test if this looks like a credit card number

    /memory:test-secret "sk-proj-abc123xyz"
        Test if this looks like an OpenAI API key

NOTES
    The value is not stored anywhere - this is purely for testing.
    Use quotes around values containing spaces or special characters.

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.
