A read-only health check for a wiki vault, scanning its pages, links, sources, and organization for problems.

Use it to detect changed source files, oversized indexes or topic hubs, contradictions, orphaned pages with no incoming links, and stale pages that may need attention.

It helps you find damaged or neglected parts of a knowledge base before they make information harder to find or trust.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00061	$0.00573
Opus 5	$0.00030	$0.00287
Sonnet 5	$0.00012	$0.00115
Haiku 4.5	$0.00006	$0.00057

Security

Grade A, and why

audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Audit — Wiki Health Check (Read-Only)

Purpose

Read-only diagnostic scan of the vault. Produce structured health report with severity classification (P0/P1/P2). NO writes.

Used by wiki-curator only.

Trigger phrases

"audit wiki"
"check vault health"
"find issues"
"wiki diagnostic"

Inputs

Optional --scope (whole vault default, or specific domain)

Outputs

Human-readable health report (markdown)
0 file writes

Workflow

Run the aggregator:

${CLAUDE_PLUGIN_ROOT}/scripts/wiki-health.sh --vault $VAULT_PATH

This delegates to:

Check	Script	Severity
Source drift (SHA mismatch raw vs sources)	verify-source-drift.sh	P0
Tree topology (index >100, hub >15)	verify-tree-topology.sh	P1
Contradictions (declared in relations)	detect-contradictions.sh	P1
Orphans (no incoming wikilinks)	find-orphans.sh	P2
Stale (forgetting curve + no incoming)	detect-stale.sh	P2

After running, classify findings in your report:

## Severity P0 (broken — block clean status)
- [item]: [file]:[line] — [reason]

## Severity P1 (degraded — should fix soon)
- [item]: ...

## Severity P2 (suggestion — quality improvement)
- [item]: ...

## Recommendations
- For each P0/P1, point to maintain skill action that would resolve it
- E.g., "Run wiki-curator maintain to split [[hub-X]] (18 members)"

Quality gate

Every finding has file path + line number (where applicable) + reason
Severity classification consistent (no P1 mixed into P0)
Report references maintain skill for fixable items

Anti-patterns

DO NOT write/edit anything
DO NOT auto-fix (that's maintain skill)
DO NOT load page contents into context unless required for the finding

Scripts used

${CLAUDE_PLUGIN_ROOT}/scripts/wiki-health.sh (aggregator)
Underlying: find-orphans, detect-stale, detect-contradictions, verify-tree-topology, verify-source-drift

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

audit is a skill published in the GitHub repository ignromanov/llm-obsidian-wiki (19 stars, last pushed 3mo ago), licensed MIT. It adds 61 tokens to every session and 573 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
