SDK API Reference

Package:

jwebot-sdk

Current API version:

Event

Event is the normalized incoming message exposed to extension code.

Important fields:

event_id
observed_at
sender
text
group_fingerprint
mention_bot
confidence
sender_confidence
body_confidence
source

sender is an untrusted display label. group_fingerprint binds kernel delivery safety but is not a selectable target.

ReplyPlan

ReplyPlan.text("visible reply")
ReplyPlan.no_reply()

Maximum visible text length is 900 characters.

Fact

Fact(kind="topic", text="likes servers", confidence=0.8)

Facts are candidates. The kernel still applies scope, sensitivity, evidence, expiry, and deduplication policy.

ExtensionResult

ExtensionResult(
    reply=ReplyPlan.text("visible reply"),
    facts=(Fact(...),),
    metadata={"source": "plugin-id"},
)

Limits:

at most 12 facts;
at most 16 metadata entries;
short string metadata only.

SingleGroupContext

Protocols exposed through the context:

commands
storage
http
services
facts
scheduler
logger

Not exposed:

GUI sender;
group selector;
raw OCR or screenshots;
ledger or SQLite;
filesystem;
environment;
subprocess or shell;
arbitrary sockets or HTTP;
credentials.

CommandRegistry

context.commands.register("/hello", handler)

The registered command must be declared in plugin.toml. The Kernel catalog detects conflicts during startup and freezes before runtime routing. User-visible description and help metadata also live in plugin.toml; bundled /功能列表 output is generated from the reviewed metadata rather than from handler code.

ApprovedHttpClient

context.http.request(
    "approved-profile",
    method="GET",
    path="/bounded/path",
    query={"key": "value"},
)

The kernel owns host allowlists, credentials, proxy, timeout, cache, and response limits. API version 1 does not expose a general-purpose URL client.

ApprovedServiceBroker

context.services.call(
    "reviewed-profile",
    operation="execute",
    payload={"bounded": "data"},
)

Reviewed local adapters use named profiles to request Kernel-owned behavior without receiving raw Ledger, provider, process, or GUI objects. Undeclared or unconfigured profiles fail closed.
