Implements the full multi-agent system for Hermes Agent, allowing a single
installation to host multiple named agents, each with its own model,
personality, toolset, workspace, and session history.
## New Files
- gateway/agent_registry.py: AgentConfig, ToolPolicy, SubagentPolicy,
AgentRegistry, TOOL_PROFILES (minimal/coding/messaging/full), and
normalize_tool_config() for shorthand YAML parsing
- gateway/router.py: BindingRouter with 7-tier deterministic routing
(chat_id > peer > guild+type > guild > platform+type > platform > default)
## Core Changes
- model_tools.py: get_tool_definitions() accepts agent_tool_policy for
per-agent tool filtering; handle_function_call() extended enabled_tools
check to gate ALL tool calls (defense-in-depth)
- gateway/session.py: build_session_key() now accepts agent_id and dm_scope
parameters, replacing hardcoded 'agent:main' with 'agent:{agent_id}'
- tools/memory_tool.py: MemoryStore accepts memory_dir parameter for
per-agent memory isolation
- agent/prompt_builder.py: build_context_files_prompt() accepts
agent_workspace for SOUL.md lookup; build_skills_system_prompt()
accepts agent_skills_dir for per-agent skill overlay
- run_agent.py: AIAgent accepts agent_tool_policy and agent_workspace,
passes policy through to get_tool_definitions()
- gateway/run.py: Initializes AgentRegistry + BindingRouter, resolves
agent per-message in _handle_message(), passes config to _run_agent(),
adds /agents command
- cli.py: --agent flag for selecting named agent profiles, /agents
slash command, agent config override for model/personality/tools
- hermes_cli/config.py: agents/bindings in DEFAULT_CONFIG, version 7
- tools/delegate_tool.py: Configurable max_depth per-agent, tool policy
inheritance from parent to child
## Config Format
agents:
main:
default: true
coder:
model: anthropic/claude-sonnet-4
personality: 'You are a coding assistant.'
tools: coding # or [tool1, tool2] or {profile: x, deny: [...]}
bindings:
- agent: coder
telegram: '-100123456'
## Tests
168 new tests across 3 test files (agent_registry, router, integration).
All 3106 tests pass.
/provider command (CLI + gateway):
Shows all providers with auth status (✓/✗), aliases, and active marker.
Users can now discover what provider names work with provider:model syntax.
Gateway bugs fixed:
- Config was saved even when validation.persist=False (told user 'session
only' but actually persisted the unvalidated model)
- HERMES_INFERENCE_PROVIDER env var not set on provider switch, causing
the switch to be silently overridden if that env var was already set
parse_model_input hardened:
- Colon only treated as provider delimiter if left side is a recognized
provider name or alias. 'anthropic/claude-3.5-sonnet:beta' now passes
through as a model name instead of trying provider='anthropic/claude-3.5-sonnet'.
- HTTP URLs, random colons no longer misinterpreted.
56 tests passing across model validation, CLI commands, and integration.
