ftl-expert-build 0.2.0

Build expert agents from documented domains

expert-agent-builder

Build expert agents from documented domains. Automates the knowledge pipeline: fetch docs, chunk large files, generate summaries, extract beliefs, derive deeper conclusions, review and repair, build FTS5 search indexes.

Install

uv tool install ftl-expert-build

Requires ftl-reasons and either claude or gemini CLI on PATH.

Quick Start

# Bootstrap a new expert agent
expert-build init rhcsa --domain "Red Hat Certified System Administrator"

# Fetch documentation
expert-build fetch-docs https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/9/ --depth 2

# Generate entries from sources
expert-build summarize --parallel 4

# Extract beliefs for review
expert-build propose-beliefs --parallel 4
# Edit proposed-beliefs.md: LLM marks each as [ACCEPT] or [REJECT]
expert-build accept-beliefs

# Run the full pipeline end-to-end
expert-build pipeline --url https://docs.example.com --parallel 4

Commands

Command	Description
init	Bootstrap a new expert agent repo
fetch-docs	Fetch documentation from URLs
chunk-pdf	Split PDFs into section-based entries
chunk-docs	Split large .md/.py/.txt files by structural boundaries
summarize	Generate entries from source documents via LLM
propose-beliefs	Extract candidate beliefs from entries via LLM
accept-beliefs	Import accepted beliefs into reasons.db
cert-coverage	Map certification objectives to beliefs
exam	Run practice questions, discover knowledge gaps
pipeline	Run end-to-end EEM construction (9 stages)
derive-review-repair	Run derive/review/repair loop on existing beliefs
index-sources	Build FTS5 chunks database for RAG search
status	Show pipeline progress

Pipeline Stages

1. Ingest (fetch-docs / chunk-pdf)
2. Summarize (LLM summaries of source documents)
3. Extract (propose-beliefs + accept-beliefs)
4-7. Derive → Review → Repair → Deduplicate (convergence loop)
8. Export (network.json + README card)
9. Index (FTS5 search database)

# Full pipeline with parallel LLM calls and recursive source discovery
expert-build pipeline --url https://docs.example.com --parallel 4 --recursive

# Resume after a crash
expert-build pipeline --resume

# Run just the knowledge refinement loop
expert-build derive-review-repair --rounds 5

Working with Large Repos

# Summarize a repo with nested directories
expert-build summarize --input-dir ~/git/my-project --recursive --parallel 4

# Chunk large files before summarizing
expert-build chunk-docs --input-dir ~/git/my-project --recursive

# Build search index
expert-build index-sources --input-dir ~/git/my-project --recursive
expert-build index-sources --input-dir entries/ --recursive --type summary

# Query with reasons
reasons search-sources "kubernetes scheduling" --db rag_fts.db
reasons ask "How does pod scheduling work?" --full-sources rag_fts.db

Features

• Parallel LLM calls — --parallel N on summarize, propose-beliefs, and pipeline
• Recursive file discovery — --recursive for nested directory structures
• Cost tracking — token counts and costs printed after every command
• Crash resilience — incremental writes, pipeline state file with --resume
• JSON pseudo-tool-calling — structured LLM output with retry for all parsing stages
• Source provenance — every entry tracks its source file, URL, and document ID
• FTS5 indexing — build search indexes compatible with reasons search-sources
