About this software

harvey 0.0.15

• /model mode [MODEL] {structured|prose|inject|none}: set or display the tool-execution strategy for a model; persisted in the model cache and survives re-probes
• File-reference injection: when a model does not reliably call tools, Harvey pre-injects the content of workspace files mentioned in the prompt as ### File: blocks
• Cannot-read retry: if a model responds indicating it cannot access a file, Harvey retries once with file content pre-loaded; retry uses RunToolLoop when in structured mode
• ModelCapability.ToolMode field and ToolMode* constants added; tool_mode column added to the model cache database with automatic migration
• Bug fix: FastProbeModel no longer overwrites a user-set tool mode on re-probe
• Bug fix: option-2 retry now clears stale toolCallRecords before history rollback, preventing inconsistent session transcripts
• Bug fix: noToolCalls computed correctly after option-2 retry using pre-rollback hadToolCalls flag
• Bug fix: option-2 retry uses RunToolLoop (not bare Client.Chat) when in structured-tools mode
• Bug fix: cantReadPhrases entry tightened from "please provide the file" to "please provide the file content" to avoid spurious retries

Harvey is an agent REPL written in Go and designed to use Llamafile models or Ollama server to access language models locally. It is a terminal based application.

The Harvey name was inspired by the play of that name by Mary Chase. I saw parallels between the story Harvey and my personal language model agent. Many people think of agents only in the context of very big companies. I think small models running on small or tiny computers are an opportunity. Harvey, is a small agent for small and tiny computers and is a play on a mythic creature. Harvey is a Púca, a software Púca. Harvey can be fun for those who take time for it. It runs on a little computers. Have an adventure and some fun with Harvey.
