 ## [Unreleased]
 
+## [1.0.0] - 2026-09-27
+
+Supports `laravel/ai` v1.0. The SDK now runs agent middleware once per generation step, not once
+per prompt. See the breaking changes below before you upgrade.
+
+### Breaking
+
+- Requires `laravel/ai` ^1.0.
+- `handle()` takes a `Laravel\Ai\PendingStep`, not an `AgentPrompt`.
+- New callback signatures:
+  - `PromptInjectionGuard`: `(PendingStep $step, Closure $next, array $detection)`
+  - `PIIRedactor`: `(PendingStep $step, Closure $next, RedactionResult $result)`
+  - `ToolApprovalGuard`: `(PendingStep $step, StepResponse $response, array $findings)`. Return value ignored. Throw to block.
+  - On a resumed run, the `PromptInjectionGuard` and `PIIRedactor` callbacks receive `(AgentPrompt $prompt, null, ...)`. Return value ignored. Throw to block.
+- Prompt callbacks run on every step. Check `$step->isFirstStep()` to act once per run.
+- Log key `provider` holds the provider name, not the class.
+
 ### Added
 
+- Approval decisions are scanned before the SDK applies them, so a block stops approved or edited tool calls before they run.
+- `InspectsApprovalDecisions` contract and `InspectsPendingSteps` concern in `promptphp/intercept-support`.
+- Log keys `step` and `invocation_id`.
+
 ### Changed
 
-### Removed
+- `PIIRedactor` redacts every user message on every step, including history replayed from a conversation store.
+- `PromptInjectionGuard` applies `sanitize` and `warn` on every step.
+- `ToolApprovalGuard` blocks streamed runs. `degraded_from` no longer appears in its logs.
+
+### Known limitations
+
+- The SDK stores the original prompt and builds the conversation title from it. Middleware can not redact either.
+- A streamed `ToolApprovalGuard` block happens after that step's text reaches the client. No tool runs.

+The Laravel AI SDK runs Intercept middleware once for each generation step, before the step reaches the provider. That defines what it can and cannot inspect.
 
 It sees:
 
 - the prompt text sent to the agent
+- prior user messages replayed from a conversation store, which PII Redactor redacts
 - edited tool arguments and rejection results supplied when resuming a paused run
 - the tool calls the model proposes for approval, with [Tool Approval Guard](/middleware/tool-approval-guard) installed

+It does not scan:
 
 - tool results returned to the model mid-run
 - attachments sent alongside the prompt
-- prior conversation history replayed from a conversation store
 - the model's response text
 
+It can not change what the SDK stores. The conversation store keeps the original prompt, and the SDK builds the conversation title from it.
+
 This matters most for indirect prompt injection. If a tool fetches a web page, reads a document, or queries a record that contains injected instructions, that content is handed to the model without passing through Intercept.
 
 Tool Approval Guard narrows that gap but does not close it. It inspects what the model *proposed* after reading poisoned content, which is where the damage usually surfaces, but it cannot inspect the poisoned content itself. It also only applies to tools that are approval-gated. A tool that runs without approval is never inspected.

-On a streamed run, the middleware cannot block. `$next()` returns before the model has proposed anything, and by the time the completion hook fires the caller has already received the streamed text.
+- tool calls to a local tool whose approval rule asks for approval
+- approvals that the provider reports itself
 
-The action therefore degrades to logging, recorded as `degraded_from`, matching the pattern used for tool approval resumes.
+A tool call that runs without approval is not inspected.

+## Streaming
 
-The security outcome still holds: the tool has **not** executed. Approval is a separate later call, so a logged-but-unblocked proposal still requires a human to act on it before anything happens.
+On a streamed run, `block` works as it does on a synchronous run. The exception stops the stream before the approval request event, so the client never receives the approval request and no tool runs.
