Wiki Status — Vault State Report

Computes a snapshot of the wiki's current state: page counts, category breakdown, ingest delta, staleness flags, and optional structural insights. Read-only — no files are modified.

Model rationale: haiku. This skill runs deterministic counts, date comparisons, and manifest lookups. All output is factual reporting from existing data; no creative synthesis or strategic judgment is required.

Before You Start

1. Read wiki/wiki/index.md — page inventory.
2. Read wiki/log.md — recent activity.
3. Read wiki/.manifest.json (if it exists) — ingest tracking ledger.

The Manifest

The manifest at wiki/.manifest.json tracks every source file ingested. If it does not exist, the vault is fresh and everything is pending.

{
  "version": 1,
  "last_updated": "2025-11-01T10:00:00Z",
  "sources": {
    "/path/to/source.md": {
      "ingested_at": "2025-11-01T10:00:00Z",
      "size_bytes": 4523,
      "modified_at": "2025-10-30T08:00:00Z",
      "pages_created": ["concepts/example.md"],
      "pages_updated": []
    }
  },
  "stats": {
    "total_sources_ingested": 18,
    "total_pages": 42
  }
}

Step 1: Page Inventory

Glob all .md files under wiki/wiki/ (exclude _archives/). Count:

• Total pages across the vault
• Pages per category (by directory prefix)
• Untagged pages — tags: [] or missing tags: field
• Pages missing summary: — frontmatter grep is sufficient; do not read page bodies
• Deprecated pages — deprecated: true in frontmatter
• Orphan pages — orphan tag in frontmatter (set by wiki-lint Check 1)

Step 2: Compute the Delta

Compare pages and sources to the manifest:

When no manifest exists, report all sources as new.

Step 3: Staleness Check

Flag pages whose updated: frontmatter date is more than 90 days old (relative to today). Use frontmatter-scoped Grep — do not read page bodies for this check.

Step 4: Report

# Wiki Status — [TIMESTAMP]

## Overview
- **Total pages:** 42 across 6 categories
- **Sources ingested:** 18
- **Last ingest:** 2025-11-01T10:00:00Z
- **Deprecated pages:** 2
- **Orphan pages:** 3 (tagged `orphan` — run cross-linker to connect)
- **Pages missing summary:** 5 (run wiki-lint to fix)

## Categories
| Category | Pages |
|---|---|
| concepts/ | 18 |
| entities/ | 9 |
| skills/ | 7 |
| synthesis/ | 5 |
| references/ | 3 |

## Delta Since Last Ingest
- **New sources:** 4
- **Modified sources:** 2
- **Unchanged sources:** 12
- **Deleted sources:** 0

### New Sources (need ingesting)
| Source | Size | Modified |
|---|---|---|
| wiki/raw/new-doc.md | 12 KB | 2025-11-03 |
| wiki/raw/meeting-notes.md | 4 KB | 2025-11-04 |

### Modified Sources (need re-ingesting)
| Source | Ingested | Modified |
|---|---|---|
| docs/architecture.md | 2025-10-01 | 2025-11-02 |

## Staleness (pages not updated in >90 days)
- `references/paper-y.md` — last updated 2025-07-01
- `entities/tool-x.md` — last updated 2025-06-15

## Recommendation

Choose one recommendation:

Step 5: Insights Mode (optional)

Triggered by: "wiki insights", "what's central", "show me the hubs", "wiki structure".

Build the wikilink graph: glob all pages, extract every [[wikilink]], compute incoming and outgoing counts per page.

Report:

1. Top hubs — 10 pages with the most incoming links. Flag sink hubs (high incoming, zero outgoing) as cross-linker candidates.
2. Fragmented tag clusters — tags with ≥5 pages and cohesion <0.15: cohesion = actual_links / (n × (n−1) / 2)
3. Orphan-adjacent pages — linked from a top-10 hub but with zero outgoing links of their own. Dead-ends in high-traffic areas — prime cross-linker candidates.

## Insights

### Top Hubs (by incoming links)
| Page | Incoming | Outgoing | Note |
|---|---|---|---|
| [[concepts/core-concept]] | 18 | 5 | connector hub |
| [[entities/key-entity]] | 12 | 0 | sink hub — cross-linker candidate |

### Fragmented Tag Clusters
- **#methods** — 6 pages, cohesion=0.08 — run cross-linker
- **#tools** — 5 pages, cohesion=0.10 — run cross-linker

### Orphan-Adjacent Pages
- [[concepts/foo]] — linked from 3 hubs, 0 outbound links

After writing insights, append to wiki/log.md:

- [TIMESTAMP] STATUS_INSIGHTS anchors=N fragmented=F orphan_adjacent=O

When to skip insights mode

• Vaults with fewer than 20 pages — not enough graph structure to be meaningful.
• Immediately after a full rebuild before any ingest has run.
