Stacked PR: This PR is stacked on top of #5511 (feature/5511-refactor-nestbot-ai-assistant).
Proposed change
Adds the NestBot evaluation framework with 28 benchmark cases, intent/tool evaluators, response coverage checks, controlled RAG fixtures, and an opt-in ai_evaluate command with JSON reports.
Phase 5 Roadmap
Part 1 — Core evaluation engine and telemetry aggregation helpers.
Part 2 — RAG evaluation and CLI implemented; full-flow evaluation pending.
Part 3 — Slack E2E, real telemetry, performance checks, and LLM judging.
Staging (in progress) — Deployable NestBot image, separate ECS service, ALB routing, and pipeline configuration.
Local Slack replies work through the separate NestBot container. Those changes are not yet pushed. Real RAG retrieval needs indexed source documents; the local index is empty.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Added AI evaluation benchmarks for response intent, tool usage, latency, and estimated token costs.
AI responses now handle greetings and unclear requests more appropriately, with updated contribution guidance and community links.
Flagship project searches return up to 15 results by default, with a maximum of 30.
Added support for AWS Bedrock and configurable embedding providers.
Bug Fixes
Improved Slack formatting for Markdown and fenced code blocks.
Tool-free AI tasks can now return direct responses.
GraphQL queries are limited to a depth of five.
Fallback responses now include the Nest link and community support channel.
Chores
Improved local and test environment setup and added commands for running AI evaluation tests.
Walkthrough
This pull request adds an AI evaluation framework with benchmark data, evaluators, telemetry, and test execution support. It also updates assistant behavior and provider configuration, Slack formatting, GraphQL extension configuration, and local and test environment settings.
Changes
AI Evaluation Framework
Layer / File(s)
Summary
Evaluation data model and benchmark dataset backend/apps/ai/evaluation/datasets/*, backend/apps/ai/evaluation/__init__.py, backend/tests/unit/apps/ai/evaluation/*
Adds evaluation schemas, 27 benchmark cases, dataset lookup functions that return deep copies, package exports, and tests for data, retrieval, and isolation.
Evaluator contracts and scoring backend/apps/ai/evaluation/evaluators/*, backend/apps/ai/evaluation/__init__.py, backend/tests/unit/apps/ai/evaluation/*
Adds the evaluator base contract and intent and tool evaluators. Tests cover intent matching, tool restrictions, expected tool use, and dataset cases evaluated with recorded tools.
Token cost and run telemetry backend/apps/ai/evaluation/telemetry/*, backend/apps/ai/evaluation/__init__.py, backend/tests/unit/apps/ai/evaluation/telemetry_test.py
Adds configured model pricing, token-cost calculation, and a tracker for token totals, latency averages and percentiles, and estimated cost.
Evaluation test execution backend/Makefile, backend/apps/ai/Makefile
Adds a Make target for evaluation tests. Backend command targets support direct execution, and the backend test target passes PYTEST_ARGS to pytest.
AI Agent Behavior and Runtime
Layer / File(s)
Summary
Project and contribution tool responses backend/apps/ai/agents/project/tools/get_flagship_projects.py, backend/apps/ai/templates/agents/contribution/tools/get_contribute_info.jinja, backend/tests/unit/apps/ai/agents/tools_test.py
Raises the default flagship-project limit to 15 and clamps requested limits to 0–30. Replaces general contribution suggestions with project- and Nest-specific guidance.
Clarification and fallback guidance backend/apps/ai/templates/agents/clarification/backstory.jinja, backend/apps/ai/common/utils.py, backend/tests/unit/apps/ai/common/utils_test.py
Adds separate prompt guidance for greetings, ambiguous requests, and out-of-scope requests. Fallback responses include the OWASP Nest URL and direct users to #owasp-community.
SlackConfig.ready() imports and calls Slack event configuration only when self.app is truthy.
Response formatting and tests backend/apps/slack/utils/format.py, backend/tests/unit/apps/slack/utils_test.py
Formats Markdown outside fenced code sections and preserves fenced content. Tests cover headings, emphasis, links, code, and Slack references.
GraphQL Extension Configuration
Layer / File(s)
Summary
Depth limiter and extension configuration backend/settings/graphql.py, backend/tests/unit/settings/graphql_test.py
Adds a query depth limiter with a maximum depth of five and configures extensions as classes or factories. Tests cover debug and fuzz configurations and introspection behavior.
Local and Test Environment
Layer / File(s)
Summary
Local Compose project and database volume docker-compose/local/compose.yaml
Sets the Compose project name to nest-local and changes the database volume to db-data-nestbot.
Docker base images and Poetry timeout docker/backend/Dockerfile.nestbot.local, docker/backend/Dockerfile.test
Sets Poetry request timeouts to 300 seconds. The test Dockerfile uses a configurable Python slim image and adds libpq-dev to the builder stage.
OWASP/Nest issue 5550: The PR adds intent and tool evaluators that can measure the routing behavior described by the issue, but it does not implement intent routing or OpenCRE tool calls.
Merge Risk: Moderate · up to be560
The example setup can prevent Nestbot from starting, and a Bedrock-only setup can break semantic search. Correct the provider defaults or requirements before merging.

Explanation
Issue #5511 is open and directly linked. Its body has a title, a checkbox showing the author will work on it, and no acceptance criteria, scope limits, or exclusions. No concrete coding requirement exists to check. The current PR description states the intent: Part 1 (Core Evaluation system) of the framework in backend/apps/ai/nestbot-ai-assistant.md. The whole-PR summary lists Part 1 files: evaluation schemas and dataset, IntentEvaluator, ToolEvaluator, TelemetryTracker, calculate_token_cost, and unit tests under backend/tests/unit/apps/ai/evaluation/. These files match the stated Part 1 scope. Limits: this assessment relies on the supplied summary, commit subjects, and the previous assessment. No source file was read in this pass. Because #5511 defines no requirement, no unmet requirement can be identified.
Full details: Out of Scope Changes check
Explanation
The current PR intent covers Part 1 of the evaluation framework. Neither #5511 nor the PR description requires the following changes. The whole-PR summary still lists them at the current head. (1) backend/settings/graphql.py adds NestQueryDepthLimiter (max depth 5), changes the extensions list to classes and factories, and wraps DisableIntrospection in a factory. Its test, backend/tests/unit/settings/graphql_test.py, covers the same change. No linked issue or PR description mentions GraphQL. (2) docker/backend/Dockerfile.test changes the base image to a PYTHON_SLIM_IMAGE argument and adds libpq-dev and POETRY_REQUESTS_TIMEOUT. docker/backend/Dockerfile.nestbot.local sets POETRY_REQUESTS_TIMEOUT to 300. (3) docker-compose/local/compose.yaml renames the Compose project to nest-local and changes the database volume. Items 1 to 3 have no stated connection to the evaluation framework or to an AI-assistant refactor. Items 4 to 9 also lack an explicit tie in the PR description: get_flagship_projects default limit and clamp, get_fallback_response text, embeddings factory provider selection, prompt templates backstory.jinja and get_contribute_info.jinja, Slack apps.py and format.py changes, and llm_config.py Bedrock support with the pyproject.toml extras. The assistant.py execute_task change is also not tied. The commit summary calls these setup changes but does not link them to Part 1 or #5511. The evaluation package, its unit tests, and the test-ai-evaluation target are in scope. backend/poetry.lock is excluded from review and does not affect this scope decision.
Resolution
Remove the unrelated changes from this PR, or move them to separate pull requests. Each pull request must link its own issue with concrete acceptance criteria. Specifically move: (1) backend/settings/graphql.py and backend/tests/unit/settings/graphql_test.py; (2) docker/backend/Dockerfile.test and docker/backend/Dockerfile.nestbot.local; (3) docker-compose/local/compose.yaml. For the AI and Slack changes in items 4 to 9 and the assistant.py change, either move them to separate linked pull requests or state in the PR description how each one supports Part 1 or #5511. Limit each change to what that link requires. Keep backend/apps/ai/evaluation/, backend/tests/unit/apps/ai/evaluation/, and the test-ai-evaluation target. If the backend/Makefile PYTEST_ARGS change, the CrewAI extra, or the Bedrock or boto3 dependency is required by the Part 1 tests, state that dependency in the PR description.

Review comments at @backend/apps/ai/evaluation/datasets/dataset.py:
- Line 211: Update the collab-001 dataset case to set expected_tools to include
both registered chapter and project search tool names, so ToolEvaluator requires
both searches to run.
Review comments at @backend/apps/ai/evaluation/telemetry/tracker.py:
- Line 41: Update the token-count validation in `record` to reject boolean
values explicitly, since `bool` is a subclass of `int`. Preserve acceptance of
non-negative integer counts and rejection of other invalid values.
Review comments at @backend/apps/slack/utils/format.py:
- Line 99: Update the formatting flow around `parts.append` so final trimming
removes boundary newlines without stripping indentation from fenced code
content; preserve the four leading spaces on an indented first code line. Add a
test covering a fenced code block whose first line is indented.
Review comments at @backend/Makefile:
- Line 95: Update the non-Poetry fallback in the Makefile command flow to run
CMD from the backend directory, matching the Poetry branch, so backend/manage.py
resolves correctly. Keep the existing command and fallback behavior otherwise
unchanged.

EMBEDDING_PROVIDER with LLM_PROVIDER set to bedrock does not silently select
Google; require an explicit embedding provider and its credentials for that case
