 ## [Unreleased]
 
+### Added
+
+- **`agents actor context show` CLI command** (#9586): Added a new ``show`` subcommand for
+  the actor context management module that displays message count, role distribution,
+  storage size, and the last N messages (default: 5) per context. Supports single-context
+  display (*``agents actor context show <name>``*) and bulk listing of all contexts via
+  ``--all`` flag. Output is rendered in Rich panels by default and can be switched to
+  machine-readable formats (JSON, YAML, plain) with ``--format``.
+
 ### Fixed
 
 - **Cross-actor subgraph cycle detection reads actor_ref field** (#1431): Fixed

CONTRIBUTORS.md

@@ -28,6 +28,7 @@ Below are some of the specific details of various contributions.
 * HAL 9000 has contributed the git worktree TOCTOU race condition fix (PR #8178 / issue #7507): replaced the unsafe mkdtemp() + rmdir() pattern with a parent-directory approach to eliminate the race window in concurrent git worktree operations.
 * HAL 9000 has contributed the git_tools TOCTOU race condition fix (PR #8255 / issue #7619): eliminated the Time-Of-Check-To-Time-Of-Use race in `_get_base_env()` by adding double-checked locking with a module-level `threading.Lock`, preventing concurrent threads from writing conflicting environment snapshots.
 * HAL 9000 has contributed the mandatory PR compliance checklist to `implementation-supervisor.md` (#9824): added an 8-item checklist to the worker prompt body with concrete items covering CHANGELOG.md, CONTRIBUTORS.md, commit footer, CI verification, BDD tests, Epic reference, labels, and milestone assignment to eliminate systemic PR merge blockers.
+* HAL 9000 has contributed the context show CLI command (#9586): implemented ``agents actor context show`` for displaying message count, role distribution, storage size, and recent messages within a named context, enabling users to inspect context state at a glance.
 * HAL 9000 has contributed comprehensive milestone documentation for v3.6.0 (Advanced Concepts & Deferred Features) and v3.7.0 (TUI Implementation) (PR #9903): split into sub-documents covering context strategies, LLM backends, resource types, A2A rename, container tool execution, scope chain resolution, cost/safety budgets, E2E workflow tests, code review examples, plugin architecture, TUI layout, persona system, reference/command input, session management, configuration, and TuiMaterializer integration.
 * HAL 9000 has contributed the LLMTraceRepository data-integrity fix (PR #8185 / issue #7505): replaced the unconditional `session.commit()` in `LLMTraceRepository.save()` with a dual-path implementation that respects the UnitOfWork pattern — flushing only when an external session is provided, and flushing + committing + closing when operating standalone. This eliminates premature transaction commits, loss of rollback capability, and a docstring/implementation mismatch.
 * HAL 9000 has contributed the ACMS Index Data Model and File Traversal Engine (PR #9664 / issue #9579): foundational data structures for indexed context entries with hot/warm/cold/archive storage tier classification, tag system, and a timeout-safe chunked file traversal engine for large projects with 10,000+ files.

+Feature: Actor context show CLI command
+  As a CleverAgents user
+  I want to view the contents and metadata of actor contexts via the CLI
+  So that I can inspect conversation state without loading it into a plan
+
+  Background:
+    Given a temporary context directory for actor context tests
+
+  # ── Single context show ────────────────────────────────────────────────
+
+  Scenario: Show existing context displays summary
+    Given an actor context named "docs" exists with messages
+    When I run actor context show "docs"
+    Then the show command returns 0
+    And the show output includes "Context:"
+    And the show output includes "Messages:"
+
+  Scenario: Show non-existent context fails
+    When I run actor context show "ghost"
+    Then the show command returns error
+
+  Scenario: Show with --all flag lists all contexts
+    Given an actor context named "alpha" exists with messages
+    And an actor context named "beta" exists with messages
+    When I run actor context show --all
+    Then the show command returns 0
+    And the show output includes "Context:"
+
+  Scenario: Show with --head option truncates messages
+    Given an actor context named "long" exists with many messages
+    When I run actor context show "long" with --head 2
+    Then the show command returns 0
+    AND the show output includes "Last 2 message(s)"
+
+  Scenario: Show empty context displays no messages indicator
+    Given an actor context named "empty" exists
+    When I run actor context show "empty"
+    Then the show command returns 0
+    AND the show output includes "(no messages)"
+
+  # ── Output format variants ─────────────────────────────────────────────
+
+  Scenario: Show outputs JSON format
+    Given an actor context named "json-test" exists with messages
+    When I run actor context show in json format for "json-test"
+    Then the show command returns 0
+    AND the show output is valid JSON
+    AND the show JSON output includes key "contexts"
+
+  Scenario: Show outputs YAML format
+    Given an actor context named "yaml-test" exists with messages
+    When I run actor context show in yaml format for "yaml-test"
+    Then the show command returns 0
+    AND the show output is valid YAML
