What it can do
| Tool | What it says it does |
|---|---|
exchange_discover_domain | Determine whether a domain publishes a Contribution Exchange profile. Returns the canonical Exchange manifest, policy URLs, signal URLs, and whether the domain is self-hosted or delegated to a Steward. Read-only — does not propose, commit, or authorize anything. Enforces HTTPS, redirect limits… |
exchange_get_attempt | Get detail for a signal attempt. Read-only. Enforces attempt visibility — actors may only read their own private attempts.

Returns authority ceilings, consideration limits, human-review requirements, and supported behavior. Read-only — does not mutate state or perform preflight evaluation. Distinguishes a missing policy from an… |

Returns whether the proposal is likely to be auto-engaged, accepted for review, escalated to a human, or rejected as invalid. READ-ONLY: performs no proposal insertion, notification, event creation, or… |
