Copass context-engineering primitives (retrieval tools, ingest tool, Context Window turn recorder) for copass-core-agents

copass-context-agents

Copass context-engineering primitives for copass-core-agents.

Three provider-neutral pieces every Copass-aware agent uses:

• copass_retrieval_tools(...) — returns discover / interpret / search as AgentTool instances, window-aware when a ContextWindow is passed.
• copass_ingest_tool(...) — returns ingest as an AgentTool so agents can promote content into durable sandbox storage.
• CopassTurnRecorder — mirrors user / assistant turns into a ContextWindow with fire-and-forget pushes and typed speaker / participants metadata.

These are the primitives the provider adapter packages — copass-anthropic-agents, copass-google-agents — compose into their run() / stream() loops. The descriptions come from copass_config so every Copass surface (TS adapters, MCP server, CLI) shows the LLM identical tool semantics.

Install

pip install copass-context-agents

Usually a transitive dep — pip install copass-anthropic-agents / copass-google-agents pulls it in.

Usage

from copass_core import CopassClient
from copass_context_agents import (
    copass_retrieval_tools,
    copass_ingest_tool,
    CopassTurnRecorder,
)

client = CopassClient(...)
window = await client.context_window.create(sandbox_id=sandbox_id)

tools = [
    *copass_retrieval_tools(client=client, sandbox_id=sandbox_id, window=window),
    copass_ingest_tool(
        client=client,
        sandbox_id=sandbox_id,
        data_source_id=my_source_id,
        default_source_type="decision",
        author="agent:support-bot",
    ),
]

recorder = CopassTurnRecorder(window=window, author="agent:support-bot")
# ...wire into your provider's stream loop; see copass-anthropic-agents or
# copass-google-agents for the full wiring.

See the provider adapter packages for the full CopassManagedAgent / CopassGoogleAgent integrations that wire these primitives into discover-as-step-1 + auto-record flows.

Speaker, participants, and provenance

CopassTurnRecorder populates the typed envelope fields on every turn it pushes through the underlying ContextWindow:

Constructor arg	Default	Effect
author	None	Forwarded as the envelope's speaker field on assistant turns (and as ChatMessage.name on the recorded turn). When unset, assistant turns get speaker="Assistant" from the role-derived fallback.
user_speaker	"User"	Speaker label on user turns. Set to a richer identity when you have one (e.g. logged-in user's display name).
participants	["User", author or "Assistant"]	Conversation roster forwarded as the envelope's participants field on every turn. Pass an explicit list to override; pass [] to opt out entirely.
include_author_prefix	False	Legacy — when True, also embeds [author=…]\n in the body string. The typed envelope path is the supported way to carry provenance now; this flag exists for backward compat with body-reading consumers and is off by default.

# Typical setup — typed speaker + auto-derived roster
recorder = CopassTurnRecorder(
    window=window,
    author="agent:support-bot",
    # participants defaults to ["User", "agent:support-bot"]
)

# Multi-party — set the roster explicitly
recorder = CopassTurnRecorder(
    window=window,
    author="agent:support-bot",
    user_speaker="Alice",
    participants=["Alice", "agent:support-bot", "system"],
)

# Opt out of participants entirely
recorder = CopassTurnRecorder(
    window=window,
    author="agent:support-bot",
    participants=[],
)

The same author flows through copass_ingest_tool as the envelope's speaker on every tool-driven ingestion. No body-prefix munging — the caller's content is sent verbatim.
