Knowledge Cutoff Awareness

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.
