The A2A messaging tools were instructing receiving agents to use the
send_message tool to reply, but that tool is often not attached to
agents anymore. This caused agents confusion when they couldn't find
the required tool.
For synchronous functions (send_message_to_agent_and_wait_for_reply,
send_message_to_agents_matching_tags, send_message_to_all_agents_in_group),
the system already captures AssistantMessage automatically, so agents
just need to respond normally.
For the async/fire-and-forget function (send_message_to_agent_async),
updated to indicate it's a one-way notification and hint that messaging
tools exist without requiring a specific one.

Models (especially Opus) take this instruction literally and re-call
the memory edit tool in a loop — one user saw 96 consecutive rethink
calls. Dropping the sentence stops the feedback loop while still
asking the agent to review the result.

* fix: replace all 'PRODUCTION' references with 'prod' for consistency
Problem: Codebase had 11 references to 'PRODUCTION' (uppercase) that should
use 'prod' (lowercase) for consistency with the deployment workflows and
environment normalization.
Changes across 8 files:
1. Source files (using settings.environment):
- letta/functions/function_sets/multi_agent.py
- letta/services/tool_manager.py
- letta/services/tool_executor/multi_agent_tool_executor.py
- letta/services/helpers/agent_manager_helper.py
All checks changed from: settings.environment == "PRODUCTION"
To: settings.environment == "prod"
2. OTEL resource configuration:
- letta/otel/resource.py
- Updated _normalize_environment_tag() to handle 'prod' directly
- Removed 'PRODUCTION' -> 'prod' mapping (no longer needed)
- Updated device.id check from _env != "PRODUCTION" to _env != "prod"
3. Test files:
- tests/managers/conftest.py
- Fixture parameter changed from "PRODUCTION" to "prod"
- tests/managers/test_agent_manager.py (3 occurrences)
- tests/managers/test_tool_manager.py (2 occurrences)
All test checks changed to use "prod"
Result: Complete consistency across the codebase:
- All environment checks use "prod" instead of "PRODUCTION"
- Normalization function simplified (no special case for PRODUCTION)
- Tests use correct "prod" value
- Matches deployment workflow configuration from PR #6626
This completes the environment naming standardization effort.
* fix: update settings.py environment description to use 'prod' instead of 'PRODUCTION'
The field description still referenced PRODUCTION as an example value.
Updated to use lowercase 'prod' for consistency with actual usage.
Before: "Application environment (PRODUCTION, DEV, CANARY, etc. - normalized to lowercase for OTEL tags)"
After: "Application environment (prod, dev, canary, etc. - lowercase values used for OTEL tags)"
The docstring incorrectly stated that fetch_webpage uses Jina AI reader.
Updated to accurately describe the actual implementation which uses:
1. Exa API (if EXA_API_KEY is available)
2. Trafilatura (fallback)
3. Readability + html2text (final fallback)

* Update archival memory docstrings for clarity
Improved docstrings for archival_memory_insert and archival_memory_search to:
- Better explain when and how to use these tools
- Provide clearer best practices
- Include more realistic examples (meeting notes, project updates)
- Emphasize semantic search vs keyword matching
- Clarify tag filtering behavior
