What is current-datetime?

A rule for checking the actual date and time before relying on them. It applies when writing timestamps, calculating deadlines, or describing when something happened.

Use it whenever a task depends on the current date, time, age of information, deadline, or timestamp.

It prevents outdated or assumed dates from being written into files or used in calculations. This is useful when timing affects the correctness of the result.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00107	$0.01221
Opus 5.5	$0.00043	$0.00488
Sonnet 5.5	$0.00021	$0.00244
Haiku 4.5	$0.00011	$0.00122

Security

Grade A, and why

current-datetime 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 2mo 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.

Current Date/Time

RULE 0: Always Verify

Run date BEFORE:

Writing any date or time value into a file (Last updated, document metadata, timestamps in code)
Stating the current date or time in a response
Calculating staleness, age, or time remaining
Any reasoning where "right now" is a fact you depend on

Never assume. The system prompt date is a snapshot from conversation start — it may be stale. The system prompt has NO time at all. Trust date output, not memory or inference.

Most Common Command
