Claude Code's token budgeting differs from documentation, impacting skill descriptions

A development team discovered discrepancies between their internal rules for AI skill descriptions and the actual behavior of Claude Code. Their system, designed to limit total skill description length to 10,000 characters, was based on documentation that did not accurately reflect Claude Code's token budgeting. The team found that Claude Code uses a different unit for its budget (tokens, not characters) and that Japanese characters are counted differently than expected, leading to a significant underestimation of actual usage. AI

    Our skill-description test passed at 2,304 of 10,000 characters while Claude Code's listing sat at 94% of its budget

    <blockquote> <p>Our commit test caps the combined length of our skill descriptions at 10,000 characters, and we sit at 2,304. On Claude Code 2.1.296 the real listing budget for a 1M-token window is 30,000, a Japanese character counts as two against it, and by that count the whole…
