Repowise Update

Trigger an incremental update of the Repowise index.

Steps

1. Check if `.repowise/` exists. If not: "This repo isn't indexed yet. Run `/repowise:init` first."

2. Run: `repowise update`

This will:

• Detect files changed since last sync commit
• Update git metadata for changed files
• Regenerate affected wiki pages (up to cascade budget of 30)
• Decay confidence scores for indirectly affected pages
• Update dead code analysis
• Update CLAUDE.md if enabled

3. Show the output summary to the user.

Available flags

• `--provider NAME` — override the LLM provider
• `--model NAME` — override the model
• `--since REF` — base git ref to diff from (overrides saved last_sync_commit). Accepts a commit SHA, tag, or branch name.
• `--cascade-budget N` — max pages to regenerate per run (default: 30)
• `--dry-run` — show affected pages without regenerating
• `-v, --verbose` — show the full changed-file list, per-phase internals, and debug logs (the run is quiet by default)

Handling $ARGUMENTS

If the user provides arguments:

• "dry-run" or "dry run" → add `--dry-run` flag
• "force" or "full" → add `--cascade-budget 999` to regenerate all stale pages
• a git ref like a SHA or tag → add `--since {ref}`
• a file path → this is not supported by update; suggest `repowise update` which auto-detects changes
