Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Analyse the graph

The graph is the search space every answer is drawn from. Its shape decides whether retrieval reaches the relevant material in a few hops or reaches nothing.

Core rule

Report shape and what it means, never fix anything. This skill is read-only.

Workflow

  1. Run the scripts rather than reading files: scripts/vault_stats.py for

counts and degree, scripts/link_check.py for orphans and breaks, scripts/graph_export.py when deeper analysis is wanted.

  1. Compute the four metrics: orphan rate, average degree, component count,

stale-page rate.

  1. Identify hubs (pages that have swallowed the graph) and bridges

(pages connecting otherwise separate clusters).

  1. Name the clusters. These are what the vault is actually about, which is

reliably different from what the user would say it is about.

  1. Say what each number means for answering questions, not just the value.

Output format

Pages  | links  | avg degree 
Orphan rate %      (healthy under 5)
Components         (main holds %)
Stale concepts %   (untouched 90+ days)

Hubs: 
Bridges: 
Clusters: 

What this means:

Calibration

Never report page count or word count as a health signal. Both rise whether the vault is improving or not.

A single reading says little. If the user has recorded previous numbers, compare against them; if not, suggest recording these.
