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
Query the vault
A query that quietly falls back on general knowledge is the most damaging thing this system can do. The owner built the vault so answers would be grounded in what they actually read, and an answer that blends the model's priors with their notes is worse than no answer, because it cannot be checked.
Core rule
Every claim in the answer comes from a page in the vault and names that page. Anything you know but the vault does not is labelled as outside knowledge or left out.
Workflow
- Start from
index.md, not from a full-text sweep. The index is the map;
reading it first keeps the context budget for actual pages.
- Follow links outward from the most relevant pages, one hop at a time.
Stop when new pages stop adding anything.
- Answer in plain language, with
[[page]]references inline. - Name the gaps. If the question has three parts and the vault covers two,
say which one it does not.
- Offer the next move when there is an obvious one: a source worth
ingesting, a synthesis page worth writing.
Output format
Plain prose, then:
Read:
Not covered: Calibration
Reading too little is the common failure: answering from three pages when the vault has fifteen relevant ones. Reading everything is the opposite failure and burns the budget on pages that add nothing.
If the vault has nothing on the topic, say so in one sentence and stop. Do not pad the answer with general knowledge to avoid an empty result.
