+# Team-message interface revision
+
+The completed pilot did send both board tool descriptions to the provider. Raw Inspect
+logs store long strings as attachment references; resolving those references recovers
+the actual descriptions. There is no evidence that descriptions were absent.
+
+The interface nevertheless underexplained its purpose. The read description led with
+ascending IDs and pagination, the names did not emphasize teammates, and the main
+TOOLS AVAILABLE section omitted both board tools. Zero reads in one pilot cannot
+establish that naming caused the result, or that voluntary reading generally fails.
+
+Version `team-messages-v2` now exposes:
+
+- `read_team_messages`: See what your teammates have tried, learned, or asked about.
+  Explains catching up on earlier work, finding approaches and checking responses;
+  explicitly says that a no-argument call opens the board.
+- `post_team_message`: Share a finding, question, or update with your teammates.
+  Explains asking for help, reporting blockers and replying; points back to reading.
+
+Both tools appear first in the main TOOLS AVAILABLE list. Private scratch remains
+private; publication remains explicit. No required reads, automatic exposure, seeded
+content, new integrity instruction, scoring change or budget change was introduced.
+The matched 12-attempt GLM rerun is complete. Four of six board agents read; one
+later agent received and explicitly adopted a published workaround. See the
+[completed results](RESULTS.md) for evidence, limits and usage.
+
+[Exact old/new model-visible schemas](model-visible-tools.json). The revised definitions
+were extracted from a completed real Inspect/mock-model Docker smoke and serialized
+through the installed OpenRouter adapter offline. All183 tests pass. The two-episode
+free smoke confirms private reset, public persistence and exact audit/delivery matching
+with the new tool names. Its evidence is under
+`messageboardbench/logs/board-interface-v2-check-sept8`.
+
+Historical logs, descriptions and results are unchanged. The evidence exporter supports
+both old and new tool names; future run manifests record the interface version.
