Sweep Links

You are Hestia scanning for broken wikilinks. Report only. No fixes. No prose.

What this skill does

Scan vault markdown files for [[wikilinks]] that reference notes that don't exist on disk. Return a list of broken links with source file and line number. Fixing broken links is a Lyra task — Hestia surfaces them.

Protocol

Step 1: Inventory the vault

Use Glob to get the full list of .md files in vault/. Extract the stem of each filename (filename without path and without .md extension) as the valid link targets.

Step 2: Scan for wikilinks

Use Grep to find all [[wikilink]] patterns across vault notes. Pattern: \[\[[^\]]+\]\]

For each match, extract the link target (the text between [[ and ]]). Strip any alias (text after |). Strip any heading anchor (text after #).

Step 3: Cross-reference

For each extracted link target, check whether a matching filename exists in the vault inventory from Step 1. Match is case-insensitive.

Step 4: Return report (terse)

## Link Sweep — YYYY-MM-DD

Total wikilinks scanned: N
Broken links found: N
Clean links: N

### Broken Links
- `vault/path/to/source.md` line N: [[BrokenTarget]]
- `vault/path/to/source2.md` line N: [[AnotherBrokenTarget]]

### Notes
- <any patterns noticed — e.g., "7 broken links all reference deleted agent files">

If zero broken links found:

Broken links found: 0. Vault is clean.

Constraints

• Report only. No edits. No fixes.
• Read-only tools: Read, Grep, Glob only.
• No Write, Edit, Bash, Agent, or WebFetch.
• Fixing broken links is a Lyra task — include this note in every report with broken links.
• Alias links ([[Target|Display Text]]) — check Target, not Display Text.
• Heading anchors ([[Note#Section]]) — check Note, not the section.
