Enum CapabilitiesAccept 

Source 
pub enum CapabilitiesAccept {
    V1,
    V2,
    V3,
}
Expand description

Capabilities schema selector (v0.6.3.1 P1 honesty patch; extended through v0.7.0 A1–A5).

HTTP callers send Accept-Capabilities: v1/v2/v3 to request a shape; MCP callers pass accept: "v1"/"v2"/"v3" to memory_capabilities. As of v0.7.0 A5, the default is v3. v2 stays supported indefinitely for backward compat — clients that pin v2 explicitly continue to get the v2 shape unchanged.

v3 carries pre-computed calibration fields stacked from the A1–A4 increments (top-level summary from A1; to_describe_to_user from A2; per-tool tools[].callable_now from A3; agent_permitted_families from A4). v3 is additive over v2 — no v2 fields are removed or retyped — so v0.6.4 SDK clients reading v3 by name still resolve every field they used to. The schema_version discriminator does change from "2" to "3", which is why clients that strict-equality-asserted on it must either relax that or pin accept="v2" explicitly.

v3 requires the live Profile (and optionally McpConfig + agent_id) for the new pre-computed fields, so callers that opt in must reach for handle_capabilities_with_conn_v3 instead of the v1/v2 entry point.

V1

V3

v0.7.0 A1–A4 — additive on top of v2: summary, to_describe_to_user, per-tool tools[].callable_now, optional agent_permitted_families. Default since A5.

Implementations§

Source§

impl CapabilitiesAccept

Source

pub fn parse(s: &str) -> Self

Parse the wire value sent by the client. Unknown / missing values fall back to v3 (the default since v0.7.0 A5). Whitespace and case insensitive. Explicit "v2"/"2" still returns V2; explicit "v1"/"1" still returns V1.
