Python SDK for cq — shared agent knowledge commons

cq-sdk

Python SDK for cq — the shared agent knowledge commons.

Lets any Python application query, propose, confirm, and flag knowledge units against a remote cq API, or store locally when no remote is configured.

Installation

uv add cq-sdk

Or with pip:

pip install cq-sdk

Quick Start

from cq import Client, FlagReason

cq = Client()  # Auto-discovers config; falls back to local-only.

# Query.
results = cq.query(domains=["api", "stripe"], language="python")

# Propose.
ku = cq.propose(
    summary="Stripe 402 means card_declined",
    detail="Check error.code, not error.type.",
    action="Handle card_declined explicitly.",
    domains=["api", "stripe"],
)

# Confirm / flag.
cq.confirm(ku.id)
cq.flag(ku.id, reason=FlagReason.STALE)

# Get the canonical agent protocol prompt.
prompt = cq.prompt()

Configuration

The client reads configuration from environment variables:

Variable	Description	Default
CQ_ADDR	Remote cq API address	None (local-only)
CQ_API_KEY	API key	None
CQ_LOCAL_DB_PATH	Local SQLite path	~/.local/share/cq/local.db

Or pass directly:

cq = Client(
    addr="http://localhost:3000",
    local_db_path=Path("~/.local/share/cq/local.db").expanduser(),
)

Knowledge tiers

Every knowledge unit has a tier: local (on-disk SQLite, never leaves the machine), private (stored on the remote API at CQ_ADDR, visible to every client pointing at the same remote), or public (open commons; not yet available).

With a remote configured, cq.propose(...) sends the unit to the remote and returns it tagged private; with no remote, or if the remote is unreachable, it writes the unit locally as local.

See the top-level README for the full description.
