name: blz-source-management description: Teaches how to discover, validate, and add llms.txt documentation sources to the blz CLI. Use when adding documentation to blz, finding llms.txt or llms-full.txt files, validating sources, refreshing content, or managing the documentation index. Covers source discovery, dry-run validation, and index file handling.

BLZ Source Management

Add and manage llms.txt documentation sources for local search.

Source Types

Type	Description	Action
llms-full.txt	Complete documentation (preferred)	Add directly
llms.txt (full)	Complete docs under standard name	Add directly
llms.txt (index)	Links to other docs (< 100 lines)	Expand linked files

Adding Sources

Standard Workflow

# 1. Dry-run to validate
blz add react https://react.dev/llms.txt --dry-run --quiet

# 2. Check output
# Good: contentType: "full", lineCount > 1000
# Index: contentType: "index", lineCount < 100 → find linked docs

# 3. Add if good
blz add react https://react.dev/llms.txt -y

# 4. Verify
blz list --json | jq '.[] | select(.alias=="react")'

Discovering URLs

Web search patterns:

"llms-full.txt" site:docs.example.com
"llms.txt" OR "llms-full.txt" <library-name>
site:github.com/org/repo "llms.txt"

Common URL patterns:

https://docs.example.com/llms-full.txt
https://example.com/llms.txt
https://example.com/llms-full.txt

Index File Handling

If dry-run shows contentType: "index" with < 100 lines:

# Inspect the index
curl -s <index-url> | head -50

# Look for .txt references like:
# ./guides.txt
# ./js.txt
# ./python.txt

# Resolve and add each linked file
blz add supabase-guides https://supabase.com/llms/guides.txt -y
blz add supabase-js https://supabase.com/llms/js.txt -y

Quality Criteria

Criteria	Good	Index	Skip
contentType	"full"	"index"	"unknown"
lineCount	> 1000	< 100	< 50
Action	Add	Expand	Investigate

Alias Best Practices

Good aliases:

• bun, react, deno (short, clear)
• supabase-guides (variant-specific)
• langchain-python (language-specific)

Bad aliases:

• b (too short)
• my-docs (vague)
• the-react-docs-2024 (too long)

Management Commands

# List sources
blz list --json
blz list --status --json    # With freshness

# Refresh sources
blz refresh --all --json    # Update all
blz refresh bun --json      # Update specific

# Remove source
blz remove bun

# Source details
blz info bun --json

Troubleshooting

Issue	Solution
404 Not Found	Try /llms.txt vs /llms-full.txt, check GitHub repo
Small line count	Likely index file - expand linked docs
contentType unknown	Inspect content manually, verify it's markdown/text
Already exists	Use blz refresh <alias> to update
