What its author says it does

Copied from the file, not written here

Retrieve the current system date and time to anchor the agent in present reality. Use for questions involving today, current time, recent events, or information newer than the model's training data to prevent knowledge-cutoff errors and fictionalization of real facts.

knowledge-cutoff-awareness

This skill allows you to get the current date and time, and perform date calculations. It uses the system's date command via a wrapper script to provide consistent current time output.

For when to use this skill, when not to use it, agent instructions, examples, and reliability notes, see references/examples.md.

Usage

Get Current Date/Time

To get the current date and time in ISO 8601 format (recommended for machine parsing):

node scripts/get_date.js
# Output: 2026-02-16T16:55:00+09:00

To get a human-readable format:

node scripts/get_date.js --human
# Output: Mon Feb 16 2026 16:55:00 GMT+0900 (JST)

Relative Dates & Calculations

You can easily calculate relative dates using simple arguments. The output will be in ISO 8601 format by default.

  • Get tomorrow:

    node scripts/get_date.js +1d

  • Get date 2 weeks ago:

    node scripts/get_date.js -2w

  • Get date 1 month from now:

    node scripts/get_date.js +1m

  • Get yesterday (keyword):

    node scripts/get_date.js yesterday

Supported units: d (days), w (weeks), m (months), y (years).

Help

To see all available options:

node scripts/get_date.js --help

Limitations

  • System Time Dependency: This skill relies on the underlying system time. If the system clock is incorrect, the output will be incorrect.
  • Timezone: The ISO 8601 output includes the local timezone offset of the machine running the script.
