Available Tools

AI Agent Utilities (28 tools)

Tools built for LLM pipelines — token management, context compression, extraction, RAG, and security.

Tool	Description
estimate_tokens	Estimate token count and cost for any text
trim_to_tokens	Trim text to fit a token budget (start/end/middle)
chunk_text	Split text into overlapping chunks by token count
compress_html	Strip scripts/styles/comments to minimize HTML for LLM ingestion
compress_markdown	Collapse blank lines, strip frontmatter, trim whitespace
compress_json	Remove nulls/empty arrays/objects, optionally sort keys
summarize_for_llm	Extractive summarization to fit a token budget (no LLM needed)

extract_json	Pull JSON objects from anywhere in LLM output
extract_tables	Parse HTML tables into JSON arrays
extract_entities	NER-lite: emails, phones, IPs, dates, credit cards, IBANs
rerank_chunks	TF-IDF reranking — sort chunks by relevance to a query
score_relevance	Score a single text's relevance to a query (0–1 + grade)
expand_query	Add synonyms and stemmed variants to improve retrieval
diff_json	Structural diff of two JSON objects — shows added/removed/changed paths
validate_json_schema	Validate data against a JSON Schema (Draft-07)
repair_json	Fix common JSON syntax errors (trailing commas, unquoted keys)
flatten_json	Flatten nested JSON to dot-notation keys
merge_json	Deep-merge multiple JSON objects
sanitize_html	Remove dangerous tags/attributes for safe rendering
deduplicate_lines	Remove duplicate lines, optionally case-insensitive

Example Prompts

Once installed, you can ask Claude things like:

• "Trim this text to 2000 tokens using the utilix trim_to_tokens tool"
• "Check this user input for PII before I log it"
• "Rerank these 10 chunks by relevance to my query about pricing"
• "Extract all JSON objects from this LLM response"
• "Compress this HTML page to minimize tokens before sending it to GPT"
• "Diff these two JSON configs and show me what changed"
• "Validate this data against my JSON Schema"
