Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
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.
How agent discovery & health will work →About
Record metrics
A single reading tells you almost nothing. Direction over months is the information, and nobody remembers what last quarter's orphan rate was.
Core rule
Four numbers, appended to a dated log, compared against the last entry. Never page count or word count.
Workflow
- Run
scripts/vault_stats.pyandscripts/link_check.py. - Record: orphan rate, average degree, component count, stale-concept rate,
with the date and total pages for context.
- Append to the metrics note. Never overwrite previous entries.
- Compare against the last snapshot and name what moved.
- Interpret only what changed. A stable number needs no commentary.
Output format
| pages
orphan rate % ( since )
avg degree ()
components (main %)
stale concepts % ()
Moved:
Watch: Calibration
A rising orphan rate with a rising page count means ingestion has stopped linking. That is the single most important pattern in this report and it should be called out explicitly, not left in the numbers.
Do not recommend more than one thing to fix. A metrics report with five action items gets ignored.
