fix(cron): allow per-job memory_enabled so cron jobs can opt into the memory system

[liuhao1024]

What does this PR do?

The cron scheduler hardcoded skip_memory=True for all cron jobs, disabling the entire memory system (holographic memory, fact_store, memory tool). This blocked legitimate use cases:

• Nightly memory optimisation jobs that mine session history for facts
• Cron jobs that need to check user preferences before acting
• Jobs that discover routing rules and want to persist them

Solution

Add a memory_enabled field (default False) to the cron job config. The scheduler reads it at runtime:

skip_memory=not job.get("memory_enabled", False)

Users opt in per job:

cronjob(action="create", schedule="0 3 * * *", prompt="...", memory_enabled=True)

Backward compatible — existing jobs continue to run with memory disabled by default.

Code Intelligence

• Analyzed: cron/scheduler.py:_run_job_impl (single call site for skip_memory), cron/jobs.py:create_job (job schema), tools/cronjob_tools.py:cronjob (user-facing tool)
• Blast radius: LOW — adds a new field with safe default; no behavior change for existing jobs
• Related patterns: skip_context_files already follows the same per-job opt-in pattern (not bool(_job_workdir))

Hi @liuhao1024 — opened #45769 which provides the default safe behavior (memory reads ON by default, writes blocked at dispatch sites). It explicitly complements your per-job memory_enabled approach here as the opt-in override for trusted maintenance jobs. No conflict — they stack. Would appreciate your review.

[ValentinSergief]

Thanks for the review on #45769! Updated the guard to check platform == "cron" so human follow-ups in cron sessions unlock memory writes (when you click a cron session and chat via TUI, _make_agent sets platform = "tui").

This keeps automated protection while allowing interactive memory cleanup — complements your per-job memory_enabled opt-in, which enables writes during the automated run itself. Nice layering.

Thanks for identifying the hard-coded cron memory exclusion; current main still passes skip_memory=True at cron/scheduler.py:3073.

Problems

• The changed cronjob() parameter is not usable by the model tool as submitted: CRONJOB_SCHEMA has no memory_enabled property (tools/cronjob_tools.py:989-1088), and the registered handler does not forward it (tools/cronjob_tools.py:1119-1144).
• The PR changes no tests. tests/cron/test_scheduler.py:960-1004 already captures AIAgent kwargs and is the natural place to cover absent/false/true job values.
• The user-facing statement that cron uses skip_memory=True remains in website/docs/user-guide/features/spotify.md:218.

Suggested changes

• Add schema and handler forwarding for memory_enabled, then test creation, update, and the scheduler's resulting skip_memory value.
• Document the default-disabled per-job opt-in.

This is an automated hermes-sweeper review.

Adding this Python parameter alone does not expose it to the model: CRONJOB_SCHEMA currently has no memory_enabled property and the registered handler does not forward it to cronjob (tools/cronjob_tools.py:989-1144). Please add both wiring points and a regression test.

Thanks @liuhao1024 — per-job memory_enabled was a solid design. We went with the simpler global flip in PR #91447 (merged as ef04d84): cron agents get memory unconditionally like every other agent, with the user-level agent.disabled_toolsets denylist as the opt-out. Closing as superseded.
