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
Set up a project
The knowledge layer answers what you know. The project layer answers what you are doing this week. Merging them fills a wiki with dead task lists and buries working files under conceptual notes.
Core rule
One goal per project, stated in its own CLAUDE.md. A project with three goals is three projects.
Workflow
- Interview if needed. What this produces, for whom, by when, and what the
agent's role is. Vague answers produce a file that makes every future session worse.
- Create the folders:
Inputs/,Process/,Outputs/,Feedback/. - Write the project
CLAUDE.md: what this is, the one goal with a date,
your role, working rules, current state. Name what the agent should not do here as well.
- Link the knowledge layer. Find concept pages the project depends on and
reference them from the project file. Copy into Inputs/ only the few that genuinely matter.
- Register it in the root
CLAUDE.mdproject list.

Calibration
Feedback/ is the folder people skip and the one that makes the system improve. If the user has no idea what would go in it, that is worth surfacing: it usually means the goal is not measurable yet.
Do not create a project for work that finishes this week. That is a task.
