Token Estimation Skill

This skill provides a way to estimate token usage for a task in the absence of a direct token counting tool.

Estimation Formulas

  1. By Characters: num_characters / 4 is a common estimate for English text.
  2. By Words: num_words / 0.75 is another standard approximation.

Application

  • For each question answered, calculate the estimated tokens based on the length of the research and the response.
  • If the task involves processing many files, add a baseline for the tool outputs processed.
  • The user requires tokens as a positive numeric value in the final JSON.

Example

If an answer contains 100 characters, the estimated tokens would be 100 / 4 = 25. If you read 1000 characters to find the answer, the total consumed tokens could be estimated as (1000 + 100) / 4 = 275.
