feat(cron): allow external memory providers in cron jobs while keeping local memory skipped by fancydirty · Pull Request #9802 · NousResearch/hermes-agent

fancydirty · 2026-04-14T17:55:38Z

Problem

cron/scheduler.py hardcoded skip_memory=True when constructing the AIAgent for a scheduled job. Because skip_memory=True prevents _memory_manager from being initialized in run_agent.py, external memory providers such as mem0 are never loaded in a cron-run session. Consequently, all mem0 tools (mem0_search, mem0_conclude, mem0_profile) are reported as unavailable to the agent, even though the user has correctly configured memory.provider: mem0 in config.yaml.

Solution

Introduce a new AIAgent parameter skip_memory_provider (default False) that controls external memory provider initialization independently from skip_memory (which controls local MEMORY.md/USER.md).

Cron jobs now pass skip_memory=True + skip_memory_provider=False, preserving the protection against local memory file pollution while allowing external memory providers to work.
Subagents and other callers are unaffected due to the default value.

Changes

run_agent.py: add skip_memory_provider parameter; move mem_config extraction so the provider block can read it even when skip_memory=True.
cron/scheduler.py: pass skip_memory_provider=False to AIAgent.
tests/cron/test_scheduler.py: add test verifying cron jobs skip local memory but not external provider.
tests/run_agent/test_skip_memory_provider.py: add unit tests for the new parameter.
website/docs/guides/cron-troubleshooting.md: document that external memory providers are usable in cron jobs.

Verification

python -m pytest tests/cron/test_scheduler.py -x → 62 passed
python -m pytest tests/run_agent/test_skip_memory_provider.py -x → 3 passed

Pull request overview

This PR aims to fix cron-run agent sessions so they can initialize and use external memory providers (e.g. mem0) while still skipping built-in local memory files (MEMORY.md / USER.md) to avoid cron prompt pollution.

Changes:

Add a new AIAgent init flag (skip_memory_provider) to decouple external provider initialization from local memory loading.
Update cron job agent construction to keep skip_memory=True while explicitly allowing external providers.
Add/adjust tests and docs around cron memory behavior; additionally, run_agent.py now expands memory-provider behavior during flush_memories() and context compression.

        self._memory_manager = None
-        if not skip_memory:
+        if not skip_memory_provider:
            try:
                _mem_provider_name = mem_config.get("provider", "") if mem_config else ""


Memory provider schemas are appended to self.tools whenever _memory_manager is initialized, regardless of enabled_toolsets/disabled_toolsets. With the new skip_memory_provider gate, this means callers that disable the memory toolset (or rely on skip_memory=True) can still unexpectedly expose external memory tools if a provider is configured. Consider additionally gating provider initialization / schema injection on whether the memory toolset is enabled for this agent instance, or otherwise ensuring toolset filtering is still respected after provider schemas are added.

+                    memory_tool_defs.append(t)


The PR description focuses on cron + skip_memory_provider, but this hunk also expands behavior in flush_memories() (adds viking_remember tool exposure/execution) and later changes _compress_context() to call external memory-provider lifecycle hooks. Please either update the PR description to include these additional behavioral changes, or split them into a separate PR to keep the cron/mem0 fix reviewable and reduce risk.

This note calls out mem0_search and mem0_conclude, but the mem0 provider also exposes other tools (e.g. mem0_profile). Consider wording this more generally (e.g. “mem0_* tools”) so the doc stays accurate if the provider’s tool surface changes, and so users don’t assume only these two tools are available.

skip_memory_provider defaults to False, which changes the meaning of existing skip_memory=True call sites: external memory providers will now be initialized (and their tools injected) even when callers explicitly set skip_memory=True. Several places appear to rely on skip_memory=True meaning “no memory provider” (e.g. gateway/run.py’s temporary flush agent comment). To preserve backward compatibility, consider making skip_memory_provider default to the value of skip_memory (e.g. accept None and coerce to skip_memory), or audit/update all existing skip_memory=True call sites to also pass skip_memory_provider=True where appropriate.

@copilot-pull-request-reviewer Thanks for the thorough review — your feedback was spot on. I've force-pushed a clean branch rebased on upstream main and addressed the issues:

Unrelated changes in diff — You were right: the original branch accidentally included local commits (OpenViking memory loss fix and AGENTS.md rule additions). The PR is now clean and only touches the cron + external memory provider fix.
Backward compatibility (skip_memory_provider default) — Changed the default from False to None. When omitted, it now coerces to the value of skip_memory:
```
if skip_memory_provider is None:
    skip_memory_provider = skip_memory
```
This means existing call sites (subagents, flush agents, batch runners, etc.) that pass skip_memory=True will continue to skip both local and external memory exactly as before. Only cron explicitly passes skip_memory_provider=False.
Doc wording — Updated the cron troubleshooting note to use mem0_* tools instead of enumerating specific tool names.
Toolset filtering concern — This is a fair observation. The provider initialization happens inside AIAgent.__init__; the schemas are appended to self.tools and then go through the normal toolset filtering logic later in the initialization. If a caller explicitly disables the memory toolset, the provider tools won't be exposed. That behavior is unchanged by this PR.

Regarding the CI failures:

Docs Site Checks is failing on team-telegram-assistant.md due to pre-existing ASCII-box formatting errors (11 errors, all in an unrelated file).
Tests is failing on tests/gateway/test_discord_reply_mode.py because the CI image is missing the discord package ('NoneType' has no attribute 'DMChannel'). This is also a pre-existing environment issue in upstream.

Both failures are unrelated to this change. All newly added tests pass locally:

tests/cron/test_scheduler.py → 62 passed
tests/run_agent/test_skip_memory_provider.py → 5 passed

@teknium1 This is a small, targeted fix for cron external memory providers (closes #9763).

What it does: Introduces skip_memory_provider so that cron jobs can use mem0 while still skipping local MEMORY.md/USER.md injection. Backward compatibility is preserved by defaulting the new flag to skip_memory.

CI status: The two failing checks are pre-existing on upstream main and unrelated to this change:

Docs Site Checks — team-telegram-assistant.md ASCII-box formatting errors
Tests — missing discord package in CI image causing test_discord_reply_mode.py and test_discord_slash_commands.py failures

All newly added tests pass locally:

tests/cron/test_scheduler.py → 62 passed
tests/run_agent/test_skip_memory_provider.py → 4 passed

Would appreciate a review when you have a moment. Thanks!

teknium1

Thanks for isolating the external-provider case and preserving the legacy default in the PR branch. Current main makes this a design decision rather than a mechanical fix.

Problems

AGENTS.md:1078-1079 explicitly says memory providers intentionally do not run during cron. The added cron flag would initialize providers, which also enables provider prompt context (agent/system_prompt.py:471-478), prefetch (agent/turn_context.py:536-550), and completed-turn sync (agent/turn_finalizer.py:462-468; agent/memory_manager.py:558-614), not just mem0_* tools.
The PR's run_agent.py hunk predates the current initialization split. run_agent.py:489-563 now forwards into agent/agent_init.py, where the provider gate lives at agent/agent_init.py:1351-1415; GitHub currently marks this PR CONFLICTING.

Suggested changes

Please have maintainers settle the cron memory read/write policy first. The linked #9763 discussion identifies #45769's read-enabled/write-guarded approach as an alternative.
If provider access is approved, port the behavior through agent/agent_init.py and test actual provider prompt/prefetch/sync behavior, including the intended cron write policy.

Automated hermes-sweeper review.

AGENTS.md:1078-1079 documents that providers intentionally do not run in cron. This enables provider prompt context, prefetch, and completed-turn sync as well as provider tools; please establish the intended cron read/write policy before bypassing that invariant.

Closing as superseded by PR #91447 (merged as ef04d84) — cron agents now pass skip_memory=False, which activates both the built-in store and external memory providers (no split needed). Thanks @fancydirty.
