Generate Mermaid PNGs

library(LLMAgentR)

my_llm_wrapper <- function(prompt, verbose = FALSE) "LLM response placeholder"

workflow <- build_doc_summarizer_agent(
  llm = my_llm_wrapper,
  output = "both",
  direction = "LR"
)

save_mermaid_png(
  x = workflow,
  file = "pkgdown/assets/document-summarizer-agent-workflow.png"
)

Step 1: Build the Summarizer

library(LLMAgentR)

my_llm_wrapper <- function(prompt, verbose = FALSE) "LLM response placeholder"

summarizer <- build_doc_summarizer_agent(
  llm = my_llm_wrapper,
  chunk_size = 4000,
  overlap = 200,
  verbose = FALSE
)

Step 2: Summarize Input

result <- summarizer("This is a short policy document about customer support SLAs.")
str(result)

Notes for Beginners

• Start with plain text to validate your setup.
• Then switch to file paths or URLs.
• Tune chunk_size and overlap for large documents.
