+#!/usr/bin/env python3
+"""Produce an issue-triage verdict with tool-less Anthropic Messages API calls.
+
+Design rationale
+----------------
+This script holds ANTHROPIC_API_KEY, but the model it calls is given NO tools. A
+prompt injection in untrusted issue content therefore has no mechanism to read the
+runner environment or filesystem (e.g. /proc/self/environ) or to post anything; the
+model can only return text. All repo/issue context is gathered deterministically by
+the workflow and this script, and passed in as data. The comment is posted by a
+separate job that holds the GitHub token but no Anthropic key, so the secret and the
+write capability are never co-located.
+
+Two calls are made:
+  1. The model proposes a few short keyword queries for finding duplicates. The script
+     (not the model) sanitizes them and runs `gh search issues` with a read-only token,
+     pinned to this repository. The worst an injection can do here is pick a poor query.
+  2. The model returns the verdict, given the issue, templates, releases, and the
+     duplicate candidates (with truncated bodies).
+
+The prompts live in the workflow (TRIAGE_PROMPT, QUERY_PROMPT) so they are reviewed
+alongside the workflow; this script only supplies the gathered context as data.
+
+Output: a single line of JSON on stdout: {"should_comment": bool, "body": str}.
+Fails closed (no comment) on any API or parse error; exits non-zero on configuration
+errors (missing key/prompt, 4xx from the API) so they are not silently swallowed.

Review the resulting diff in the JSON files as part of the PR; a reviewer should be able to see and reason about every query-count change.
 
+To run the tests without enforcing the baselines, set `SKIP_QUERY_COUNTS=1`. The tests still make their requests and run their functional assertions, but the baselines are not read and the query counts are not checked against them. This helps when the same tests run against several NetBox versions, such as in a plugin's CI matrix, because query counts can differ between releases even when the tested code is unchanged. Enforce the baselines against one reference version and skip them on the others.

 The default nested representation of an object is defined by the `brief_fields` attributes under the serializer's `Meta` class. (Older versions of NetBox required the definition of a separate nested serializer.)
 
+When a serializer is used with `nested=True`, it resolves its input to an existing object and does not run its validators or `validate()` method.

 In addition to the base NetBoxModelSerializer class, the following serializer classes are also available for subclasses of standard base models.

 Custom fields can be mixed with built-in fields to further narrow results. When creating a custom string field, the type of filtering selected (loose versus exact) determines whether partial or full matching is used.
 
+Boolean custom fields support the `empty` [lookup expression](#lookup-expressions), which matches objects holding no value for the field. A value of `false` is not considered empty. For example, the following query will return only sites where a boolean custom field named `managed` has not been set:

 ## Lookup Expressions
 
 Certain model fields also support filtering using additional lookup expressions. This allows
