From 4929838868a1fe44b4a5dfa13b4a804f0f9da072 Mon Sep 17 00:00:00 2001 From: Shile Zhang Date: Fri, 12 Jun 2026 14:53:22 +0800 Subject: [PATCH] feat(memory): add memory_sessions and memory_timeline tools Session history query tools: - memory_sessions(limit): list historical session summaries from facts/summary/ directory. Returns session_id, created_at, tool_calls, tools_used, files_modified, description. - memory_timeline(session_id, limit): show tool call timeline from persistent session logs (.anolisa/session-logs/.jsonl). Returns timestamped entries with tool name, path, status, errors. Helper functions: - parse_frontmatter_flat(): extract key:value from YAML blocks - extract_body(): get markdown body after frontmatter - parse_count_from_body(): find numeric counts in text - parse_list_from_body(): extract comma-separated lists Tests: 5 new session history tests Total: 0 failures Tools: 23 total (was 21) Signed-off-by: Shile Zhang --- src/agent-memory/src/config.rs | 22 +- src/agent-memory/src/mcp_server/tools.rs | 26 ++ src/agent-memory/src/tools/mod.rs | 1 + src/agent-memory/src/tools/session_history.rs | 283 ++++++++++++++++++ .../tests/mcp_integration_test.rs | 2 + src/agent-memory/tests/profile_test.rs | 4 +- 6 files changed, 318 insertions(+), 20 deletions(-) create mode 100644 src/agent-memory/src/tools/session_history.rs diff --git a/src/agent-memory/src/config.rs b/src/agent-memory/src/config.rs index d66674ede..c3f5bed7b 100644 --- a/src/agent-memory/src/config.rs +++ b/src/agent-memory/src/config.rs @@ -142,11 +142,9 @@ pub struct ConsolidationConfig { /// BM25 score threshold for conflict detection.
