   (#828)
 
 
+- **Implementation Worker PR Inspection Permissions** (#8175): Added
+  `forgejo_list_pull_request_files` and `forgejo_get_pull_request_diff` permissions
+  to `implementation-worker.md`. These read-only permissions enable the worker to
+  directly inspect PR changes in PR fix mode, reducing unnecessary full-repo clones
+  and aligning permissions with the `pr-reviewer` agent. Also added `curl *`,
+  `printenv *`, and `echo $*` bash permissions needed for Forgejo API calls,
+  environment variable checks, and basic shell operations.
+
 - **TDD Issue-Capture Test Activation** (#7025): Replaced 234 bare `@skip` tags
   across 82 Behave feature files with the correct `@tdd_expected_fail @tdd_issue
   @tdd_issue_<N>` tag system. Scenarios whose referenced bugs were already fixed
