# Ephemeral Channels (TTL testing)

# ACP (Agent Communication Protocol — sprout-acp harness)
# -----------------------------------------------------------------------------
# The ACP harness bridges Sprout events to AI agents. Each env var below maps
# to a CLI flag of the same name (lowercase, hyphens → underscores). All values
# are optional unless noted; defaults are shown in comments.
#
# Quick start:
#   SPROUT_PRIVATE_KEY=<hex>  SPROUT_RELAY_URL=ws://localhost:3000  sprout-acp

# ── Identity & auth ──────────────────────────────────────────────────────────
# Nostr private key (hex or bech32). REQUIRED — identifies the agent on the relay.
# SPROUT_PRIVATE_KEY=<32-byte hex or nsec1… private key>

# Bearer token for relay authentication (when SPROUT_REQUIRE_AUTH_TOKEN=true).
# SPROUT_API_TOKEN=

# Relay WebSocket URL the harness connects to.
# Note: the relay itself uses RELAY_URL (above); this is the ACP harness's
# connection target — they happen to point at the same place in local dev.
# SPROUT_RELAY_URL=ws://localhost:3000

# ── Agent subprocess ─────────────────────────────────────────────────────────
# Binary to spawn as the AI agent (e.g. "goose", "codex-acp", "claude-code").
# SPROUT_ACP_AGENT_COMMAND=goose

# Comma-separated arguments passed to the agent binary.
# Goose default: "acp". Codex/Claude default: "" (empty).
# SPROUT_ACP_AGENT_ARGS=acp

# Binary for the Sprout MCP server sidecar (provides channel tools to the agent).
# SPROUT_ACP_MCP_COMMAND=sprout-mcp-server

# Number of parallel agent subprocesses (1–32).
# SPROUT_ACP_AGENTS=1

# Desired LLM model ID. Applied to every new ACP session.
# Use `sprout-acp models` to discover available model IDs.
# SPROUT_ACP_MODEL=

# ── Timeouts & sessions ──────────────────────────────────────────────────────
# Max seconds per agent turn before timeout (default 320 = ~5 min).
# SPROUT_ACP_TURN_TIMEOUT=320

# Max turns per session before proactive rotation. 0 = disabled (rotate only
# on MaxTokens / MaxTurnRequests). Recommended: 50 for long-running agents.
# SPROUT_ACP_MAX_TURNS_PER_SESSION=0

# ── Prompts ──────────────────────────────────────────────────────────────────
# System prompt injected into every agent session (inline text).
# SPROUT_ACP_SYSTEM_PROMPT=

# Path to a file containing the system prompt (mutually exclusive with above).
# SPROUT_ACP_SYSTEM_PROMPT_FILE=

# Message sent to the agent immediately after session creation.
# SPROUT_ACP_INITIAL_MESSAGE=

# ── Heartbeat ────────────────────────────────────────────────────────────────
# Seconds between heartbeat prompts. 0 = disabled. Must be 0 or ≥10.
# Recommended: 60 for long-running agents to prevent idle session timeouts.
# SPROUT_ACP_HEARTBEAT_INTERVAL=0

# Heartbeat prompt text (inline). Mutually exclusive with file variant.
# SPROUT_ACP_HEARTBEAT_PROMPT=

# Path to a file containing the heartbeat prompt.
# SPROUT_ACP_HEARTBEAT_PROMPT_FILE=

# ── Subscription & filtering ─────────────────────────────────────────────────
# Subscribe mode: "mentions" (default), "all", or "config" (rule-based).
# SPROUT_ACP_SUBSCRIBE=mentions

# Comma-separated event kind numbers to subscribe to (overrides mode defaults).
# SPROUT_ACP_KINDS=

# Comma-separated channel UUIDs to limit subscription scope.
# SPROUT_ACP_CHANNELS=

# Set to true to disable the @-mention filter in mentions mode.
# SPROUT_ACP_NO_MENTION_FILTER=false

# Path to TOML config file for rule-based subscriptions (config mode).
# SPROUT_ACP_CONFIG=./sprout-acp.toml

# ── Dedup & self-ignore ──────────────────────────────────────────────────────
# How to handle duplicate events: "queue" (default) or "drop".
# SPROUT_ACP_DEDUP=queue

# Set to true to process the agent's own messages (default: ignore self).
# SPROUT_ACP_NO_IGNORE_SELF=false

# ── Context ──────────────────────────────────────────────────────────────────
# Max context messages fetched for thread replies and DMs (0–100). 0 = disabled.
# SPROUT_ACP_CONTEXT_MESSAGE_LIMIT=12

# ── Presence & typing ────────────────────────────────────────────────────────
# Set to true to disable automatic online/offline presence status.
# SPROUT_ACP_NO_PRESENCE=false

# Set to true to disable typing indicators while the agent is processing.
# SPROUT_ACP_NO_TYPING=false

# ── Advanced tuning ──────────────────────────────────────────────────────────
# Event channel buffer capacity (WebSocket → harness). Increase for
# high-throughput agents. Minimum 1.
# SPROUT_ACP_EVENT_BUFFER=256

# ── Legacy aliases ───────────────────────────────────────────────────────────
# These are accepted for backward compatibility but the canonical names above
# are preferred:
#   SPROUT_ACP_PRIVATE_KEY  → SPROUT_PRIVATE_KEY
#   SPROUT_ACP_API_TOKEN    → SPROUT_API_TOKEN
