Reliability & compatibility
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
Write a research report
A report that presents only findings looks stronger and is less useful, because the reader cannot tell where it is load-bearing and where it is thin.
Core rule
Scope against the vault first. Most of the work in a good report is knowing what you do not need to look up.
Workflow
- Inventory what exists. Which pages cover this, what is thin, what is
missing entirely. That answer is the research plan.
- Report the gaps before writing, so the user can decide whether to ingest
more first.
- Write from pages, citing pages. Every claim traces to a source page with
a URL behind it.
- Record disagreement where sources conflict, with dates and who says what.
- State what could not be established and what evidence would change the
conclusion.
- Save to
output/and offer to ingest it back as a source.
Output format
## Question
## What the vault covers (with [[page]] citations)
## Where sources disagree
## What I could not establish
## What would change this
## Pages read:
Calibration
If the vault covers less than half the question, say so at the top rather than producing a report that reads as complete.
Never fill a gap from general knowledge without labelling it as outside the vault. A report whose sources cannot be checked is worth less than a short one that can.
