Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • apply_json_semantic

    Prune a JSON string using signal keys. Auto-classifies URL against built-in API rules (GitHub, npm, HackerNews, weather, Reddit, JSONPlaceholder). Keeps only signal-matched keys, applies alias remapping, flattens to markdown.

  • classify_url

    Check if a URL matches any built-in API skin rules (GitHub, npm, weather, etc.). Returns the matched rule with signals and aliases, or null.

  • compress

    Single front door for context compaction. Auto-detects CLI output when command is supplied, JSON when parseable, otherwise applies safe text cleanup without rewriting prose.

  • estimate_tokens

    Estimate the token count for a string. Uses grapheme-aware counting (via Intl.Segmenter) for accurate estimates on CJK, emoji, and combining marks.

  • fetch_optimized_data

    Fetch a public API or webpage and return compact context. Structured JSON is pruned with URL-specific rules when available.

  • reduce

    Run the full Tokenjuice reduction pipeline on command output. Applies rule matching (136 rules), ANSI stripping, truncation, JSON semantic pruning, and other reducers based on the matched rule set.

  • skin_reasoning

    Optimize natural language text by removing linguistic noise (hedging, filler words, redundant phrases). 14-29% typical reduction.

  • strip_ansi

    Strip ANSI escape codes from text. Useful for cleaning terminal output before processing.
