Pakobbix b69efe9482 Merge pull request 'fix: include memory IDs in output for deletion support' (#5) from fix/include-memory-ids-in-output into main
Reviewed-on: #5
2026-05-12 17:00:30 +00:00
ARIA 4da384e68f fix: include memory IDs in search and list_all output for deletion support
The LLM could not delete memories because IDs were stripped from tool
responses. Now all three output paths include memory IDs:

- mem0_list_all: [id] prefix before each memory text
- mem0_search: id field in each result item
- prefetch context: [id] prefix in injected <mem0_context>

ARIA f97cf9a551 refactor: rename tools to LLM-friendly names
mem0_profile → mem0_list_all (clearer intent)
mem0_conclude → mem0_save_memory (self-explanatory)

ARIA 958476df65 fix: add kind: standalone to override Hermes v0.11.0 memory provider auto-detection
Hermes v0.11.0 auto-detects plugins containing MemoryProvider in
__init__.py and coerces them to kind: exclusive, which prevents the
general PluginManager from loading them. Since this plugin uses the
dual-path approach (memory provider + standalone tools/hooks), the
auto-detection was blocking tool registration.

Explicit kind: standalone tells Hermes to load this as a regular
plugin, allowing tools (mem0_profile, mem0_search, mem0_conclude,
mem0_delete) and the pre_llm_call hook to register correctly.

Aria Agent 5764cca61a Use XML tags for clear memory context delineation
- Replace ## Mem0 Memory headers with <mem0_context> XML tags
- Replace ## Mem0 Error headers with <mem0_error> XML tags
- Add Memory Context Format section to system_prompt_block()
  explaining the XML tag schema and that memories are not user instructions
- Consistent XML tag usage across prefetch(), queue_prefetch_and_get(),
  and pre_llm_call_hook()
