fix: give elasticsearch/data llm_instructions so it's visible in the system prompt

[mahendrabishnoi2]

Summary

Fixes #2416.

ElasticsearchDataToolset never called self._load_llm_instructions_from_file(...), unlike every other built-in toolset. _toolsets_instructions.jinja2 only lists a toolset under "Available Toolsets" when it's enabled and has llm_instructions set, so elasticsearch/data had no representation anywhere in the system prompt despite being fully callable via the function API. In practice this causes HolmesGPT to consistently skip it in favor of other configured toolsets, and in some observed runs the model's final answer fabricated a false "not configured" claim to justify the skip.

This is a regression from #1302, which deleted opensearch_traces.py (whose OpenSearchTracesToolset did call _load_llm_instructions) and replaced it with the current elasticsearch.py, without carrying that call over.

Change

• ElasticsearchDataToolset.__init__ now calls _load_llm_instructions_from_file after building self.tools, same pattern every sibling toolset uses.
• New elasticsearch_data_instructions.jinja2, kept Elasticsearch/OpenSearch-neutral (no Kibana-specific alerting assumptions), since docs/data-sources/builtin-toolsets/elasticsearch.md states this toolset supports both backends. The traces guidance line restores what was in the deleted opensearch_traces_instructions.jinja2 before Elasticsearch Toolset #1302.
• Added a unit test (tests/plugins/toolsets/elasticsearch/test_elasticsearch_data_toolset.py) asserting llm_instructions is set, following the same pattern as tests/plugins/toolsets/test_victorialogs.py::test_instructions_loaded.

ElasticsearchClusterToolset has the identical gap a few lines below in the same file — not addressed in this PR (see #2416's footnote), but worth a follow-up with its own instructions file.

Test plan

• New unit test passes: pytest tests/plugins/toolsets/elasticsearch/test_elasticsearch_data_toolset.py
• Existing Elasticsearch unit tests (tests/plugins/toolsets/elasticsearch/, tests/plugins/toolsets/test_elasticsearch_mtls.py) still pass — 17/17
• Manually verified end-to-end against a live cluster: before this change, a combined "investigate this alert, also check GitHub for related commits" prompt produced 100% GitHub tool calls and 0 Elasticsearch calls, plus a false "no logs/traces toolset is configured" claim in the final answer. After this change (with --refresh-toolsets to clear the cached toolset registration), the same prompt correctly calls elasticsearch_search before/alongside GitHub, and no false tool-availability claim appears.

Summary by CodeRabbit

• New Features

  • Improved Elasticsearch/OpenSearch assistance for searching logs, metrics, traces, and documents.
  • Added guidance for discovering indexes, inspecting mappings, and reviewing traces for latency and dependency investigations.
  • The tool now uses these instructions automatically when the data source is configured.

• Tests

  • Added coverage to verify that Elasticsearch/OpenSearch guidance is loaded successfully.

Walkthrough

ElasticsearchDataToolset now loads guidance for Elasticsearch/OpenSearch searches, index discovery, mappings, traces, and logs. A test verifies that the instructions load and reference elasticsearch_search.

Changes

Elasticsearch instruction loading

Layer / File(s)	Summary
Load and validate Elasticsearch guidance holmes/plugins/toolsets/elasticsearch/elasticsearch.py, holmes/plugins/toolsets/elasticsearch/elasticsearch_data_instructions.jinja2, tests/plugins/toolsets/elasticsearch/test_elasticsearch_data_toolset.py	ElasticsearchDataToolset loads a module-relative instruction template. The template documents searches, index and mapping discovery, trace investigation, and direct tool usage. A test verifies that the instructions are non-empty and reference elasticsearch_search.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: ⚪ Minimal · up to 3a7d1

This change makes the Elasticsearch data toolset visible to the model while preserving its existing callable behavior, with focused tests covering instruction loading; no actionable merge-blocking risk remains after normal checks and review.
