Add additional Python prompt-injection sinks for uncovered SDK methods

Cover prompt-carrying public API methods that were missing from the
framework models:

- OpenAI: videos.create/create_and_poll/edit/remix/extend (Sora, user),
  beta.realtime.sessions.create instructions (system), and role-filtered
  beta.threads.messages.create content (Assistants API).
- Anthropic: legacy completions.create prompt (user).
- agents: Agent.as_tool tool_description (system).
- Google GenAI: caches.create CreateCachedContentConfig system_instruction
  (system) and contents (user).

+</p>
+</overview>
+
+<recommendation>
+<p>Do not include user input in system-level or developer-level prompts or tool descriptions. Use methods meant for user input or messages with a "user" role to provide user content or context to the AI model.

+If user input must influence the system prompt or tool description, validate it against a fixed allowlist of permitted values.</p>

+<p>In the following example, a user-controlled value is inserted directly into a system-level prompt
+without validation, allowing an attacker to manipulate the AI's behavior.</p>
+<sample src="examples/prompt-injection.js" />
+<p>One way to fix this is to provide the user-controlled value in a message with the "user" role,

+<example>
+<p>Prompt injection is not limited to system prompts. In the following example, which uses an agentic
+framework, a user-controlled value is included in the description of a tool that is exposed to the
+model. An attacker can use this to manipulate the model's behavior in the same way.</p>
+<sample src="examples/tool-description-injection.js" />
+<p>The fix keeps the tool description as a fixed, trusted string and passes the user-controlled topic
+as part of the user input instead, so the model treats it as user content rather than as a trusted
+instruction.</p>

+  "qhelp.dtd">
+<qhelp>
+
+<overview>
+<p>If untrusted input is included in a user-role prompt sent to an AI model, an attacker can inject
+instructions that manipulate the model's behavior. This is known as <i>indirect prompt injection</i>
+when the malicious content arrives through data the model processes, or <i>direct prompt injection</i>
+when the attacker controls the prompt directly.</p>
+
+<p>Unlike system prompt injection, user prompt injection targets the user-role messages. Although
+user messages are expected to carry user input, passing unsanitized data directly into structured
+prompt templates can still allow an attacker to override intended instructions, extract sensitive
+context, or trigger unintended tool calls.</p>
+</overview>
+
+<recommendation>
+<p>To mitigate user prompt injection:</p>
+<ul>
+<li>Ensure that all data flowing into user input is intended and necessary for the purpose of the AI system.</li>
+<li>Ensure the system prompt clearly describes the purpose, scope and boundaries of the AI system. Instruct the system to deny input that falls outside these boundaries.</li>
+<li>If creating a prompt out of multiple user-controlled values, assume that each of them can be malicious. Ensure the range of possible values is restricted and validated.
+For example, if a prompt includes a question and the intended language to respond in, validate that the language is one of the supported options.</li>
+<li>Consider using guardrails on the input like the OpenAI guardrails library to enforce constraints and prevent malicious content from being processed.</li>
+<li>Apply output filtering to detect and block responses that indicate prompt injection attempts.</li>
+</ul>
+</recommendation>
+
+<example>
+<p>In the following example, user-controlled data is inserted directly into a user-role prompt
+without any validation, allowing an attacker to inject arbitrary instructions.</p>
+<sample src="examples/user-prompt-injection.js" />
+
+<p>The following example applies multiple mitigations together, and only includes data that is
+necessary for the task in the prompt:</p>
+<ul>
+<li>The user-controlled value that selects behavior (the response language) is validated against a
+fixed allowlist before it is used in the prompt, restricting its possible values.</li>
+<li>The request is sent through a guarded client, so an input guardrail (here, the OpenAI guardrails
+library) inspects the user input and blocks prompt-injection attempts before the model sees it.</li>
+<li>The system prompt clearly describes the assistant's scope and instructs it to ignore embedded
+instructions and refuse anything outside that scope.</li>
+<li>Output filtering uses a separate LLM call to inspect the model's response and blocks it if it
+has leaked the system prompt or other internal instructions, complementing the input guardrail.</li>
+</ul>
