What is discoverable?
The default directory is the platform: capabilities, supported protocol projections, auth requirements, and safe activation paths. User agents, group agents, source roots, runs, traces, and provider contexts remain private unless a verified user publishes an artifact, enables public discovery, joins a group/session, or grants a signed capability.
Owner-scoped personal agents for memory, connected-service context, approvals, reminders, calendar coordination, email triage, and delegated actions.
- Discoverability
- Private by default. WebFinger, public cards, and directory entries appear only for users who explicitly enable public discovery.
- Auth and authority
- Owner Firebase/session auth for first-party use; user-authorized AgentGrant bearer tokens scoped to agent:a2a-message for third-party A2A calls.
Useful when you want to
- Answer preference/context questions
- Coordinate calendar availability
- Accept reminders or delegated tasks
Group-scoped facilitators coordinate shared threads, participant context, private sidecars, delegation logs, and personal-agent requests without holding user credentials.
- Discoverability
- Group/session scoped. A facilitator is discoverable to participants through the group or signed capability, not as a public crawlable person.
- Auth and authority
- Verified participant session, group membership, scoped delegation grants, and personal-agent policy checks. Caller-supplied handles are never authority.
Useful when you want to
- Coordinate group logistics
- Request scoped disclosures from personal agents
- Keep owner-visible delegation logs
Agentic coding, source, validation, evidence, submit/watch, previews, budgets, traces, and durable work orchestration built on Wheelie platform APIs.
- Discoverability
- Public platform metadata and shared artifacts can be crawled. Private workspaces, source roots, runs, and traces require verified Wheelie auth or signed capabilities.
- Auth and authority
- Verified Wheelie session, developer token, service identity, source/repo grants, budget grants, idempotency keys, and typed evidence receipts.
Useful when you want to
- Turn a work item into a PR
- Run validation and publish evidence
- Share a public-safe run or repro artifact
X, GitHub, Slack, and other mention-style flows convert relevant public or workspace context into a signed claim link and authenticated Gravity/Wheelie chat.
- Discoverability
- Discovery is the activation affordance: public-safe triage, claim/auth link, contextual personal chat, then optional budgeted run or approved public artifact.
- Auth and authority
- Signed short-lived claim URLs bind platform, thread, nonce, and context. Real work starts only after verified auth, budget, and provider/repo grants.
Useful when you want to
- Reproduce this public bug report
- Make this a PR after repo authorization
- Turn this thread into a work item
MCP tools are generated, scoped projections of Wheelie operation contracts and hosted-app capability metadata, not a separate business-logic layer.
- Discoverability
- Tool lists are dynamically filtered by verified grant/session, support level, side-effect class, and scopes. There is no anonymous global MCP tool catalog.
- Auth and authority
- Scoped developer/user grants, OAuth or service identity where applicable, idempotency/dry-run posture, redaction policy, and audit receipts from canonical contracts.
Useful when you want to
- Inspect available app capabilities
- Call read-only scoped tools
- Request approval for side-effectful operations
Continua/Wheelie can publish service-level agent metadata and consume or expose A2A-compatible delegation surfaces with tainted-output and support-state controls.
- Discoverability
- Crawlers and registries can read the service card and manifest. User-agent routing remains opt-in, grant-scoped, or trust-circle scoped.
- Auth and authority
- AgentGrant bearer tokens for third-party message calls, first-party sessions for owner flows, and capability checks for delegated or remote-agent work.
Useful when you want to
- Fetch the platform agent card
- Delegate a scoped task with a grant
- Discover support state for remote-agent capabilities
