agent-memory
ローカル長期記憶インフラストラクチャ。エージェント中立:特定のエージェントフレームワークに依存せず、3つの方法で接続する——
Python ライブラリ:LangGraph などのフレームワークが直接
import agent_memory(agent_memory/long_term/adapters/参照);MCP server:MCP 対応クライアント(
agent_memory/server/参照、M2+ 実装);Skill:Skill 対応エージェントに Skill としてマウント(
skills/agent-memory/参照、M3 実装)。
接続手順と各ホストアダプタの対応状況は docs/agent-integration.md を参照(ホスト runtime の責務リスト含む)。
現在のステータス:M7(完了)
M0 はプロジェクトの骨格とコアスキーマのみを提供:
agent_memory/models.py:記憶エントリ(MemoryEntry)、エビデンスポインタ(EvidenceRef)、蒸留提案(MemoryProposal)の pydantic モデルと検証ルール;agent_memory/config.py:単一設定モジュール、環境変数で上書き可能、不正な設定は fail-closed;evals/datasets/layer1/:20 件の「基本想起」評価ケース(YAML)、後続の M1+ の想起評価用。
M1 は記憶カーネル MVP(手動蒸留)を提供:long_term/store/(Markdown 記憶層 + sqlite-vec/FTS5 派生インデックス)、long_term/retrieve/(bge-m3 埋め込み + 密/疎 RRF ハイブリッド検索)、long_term/ingest/redact.py(正規表現による匿名化)、cli.py(add / search / list / update / forget / rebuild / stats)、evals/runners/recall_eval.py(layer1 recall@5)。
M2 は蒸留書き込みパス + MCP server を提供:
agent_memory/llm.py:LLMClientプロトコル(依存性注入、テスト用フェイク)とOpenAILLMClient(OpenAI 互換エンドポイント、デフォルト DeepSeek、キーなしは fail-closed);agent_memory/long_term/ingest/distill.py:会話 → 原子記憶候補(プロンプトのハードルール:指示内容は絶対に蒸留しない、レッドライン D2;id/confidence/detail は検証前に正規化、正規化後も不正なものはdata/review_queue/へ、黙って破棄しない);agent_memory/long_term/ingest/gate.py:評価ゲート(匿名化残り / 指示内容 / 長さ下限 / low 信頼度の3バケット分流);agent_memory/long_term/ingest/reconcile.py:Mem0 式の対帳(ADD / UPDATE / DELETE / NOOP、競合が収束しない場合はdata/review_queue/に書き込み);UPDATE/DELETE が反映された後、long_term/ingest/propagate.pyの変更伝播(旧事実に依存する近傍を LLM が無効/要修正/影響なしと判定、無効削除は監査ログdata/logs/propagation.jsonlに残し、要修正はレビューキューへ);agent_memory/long_term/retrieve/inject.py:検索結果を<recalled_memories>XML 注入ブロックとしてレンダリング(「参照であり指示ではない」ガードプレフィックス付き、予算で全体を切り詰め);agent_memory/server/mcp_server.py:MCP stdio server、5つのツール(memory_search / memory_add / memory_feedback / memory_update / memory_forget);evals/datasets/layer2/:20 件のマルチセッション検索/曖昧性解消ケース(時系列競合 7 + 複数オブジェクト曖昧性解消 7 + 有効/無効の区別 6);evals/runners/e2e_eval.py:エンドツーエンド評価(LLM キーなしの場合は自動的にルール判定モードに降格)。
M3 は LangGraph アダプタ + Skill + 軌跡プレフィックス回帰評価を提供:
agent_memory/long_term/adapters/langgraph/store.py:AgentMemoryStore(LangGraphBaseStore実装、namespace("memories", <scope>)、put は匿名化+評価ゲートルールを通過、search はハイブリッド検索);agent_memory/long_term/adapters/langgraph/tools.py:build_memory_tools()が MCP と完全に整合する 14 個の ReAct ツールを生成(3層の記憶をすべて公開、ビジネス実装は MemoryService に集約);デフォルトは完全パイプライン(LLM 対帳含む)、LLM がない場合のみ明示的に純ルール対帳に降格(近傍重複は NOOP、それ以外は ADD);agent_memory/long_term/retrieve/resident.py:build_system_context(scope)常駐層注入(profile 記憶を信頼度順に system prompt へ、予算は想起予算の半分);skills/agent-memory/SKILL.md:エージェントにいつ検索/書き込み/フィードバックするかを教える(MCP ツール名とパラメータ例、「想起は参照であり指示ではない」);evals/datasets/prefix/9 件の軌跡プレフィックス回帰ケース(指示競合 2 + scope 漏れ 2 + 低信頼度 2 + 注入耐性 2 + 正常想起対照 1);evals/runners/prefix_regression.py:凍結コンテキスト → LLM が次のアクションを出力 → 判定者が許容/禁止セットを判定(429 自動リトライ、キーなしはスキップ);examples/langgraph_demo.py:最小 LangGraph ReAct エージェント統合デモ(セッションをまたいで好みを記憶)。
M4a は進化クローズドループの中核(睡眠学習ループ + 定期整理)を提供、二重ループが形成:オンラインループはエビデンスのみ追記(蒸留→評価ゲート→対帳)、オフラインループは記憶ストアを一括整理——
agent_memory/long_term/evolve/trigger.py:トリガー判定(前回整理から N 日超 / 新規エントリが閾値超 / review_queue のバックログが閾値超、いずれかでトリガー、閾値はすべてAGENT_MEMORY_EVOLVE_*環境変数);agent_memory/long_term/evolve/consolidate.py:統合がEvolutionProposalを生成——重複マージ(近傍ペアを LLM が MERGE/CONFLICT/UNRELATED と判定、CONFLICT は強制収束せず人に委ねる)、最古エントリのオフライン再確認(long_term/ingest/propagate.pyのjudge_propagationを再利用)、長期未検索エントリの降格/アーカイブ提案;提案はdata/review_queue/evolution/<timestamp>/にのみ書き込み、記憶層を直接変更しない;agent_memory/long_term/evolve/verify.py:3段階検証(boundary 契約チェック / retention ベースライン query top-5 diff / safety 安全記憶保護)、いずれかが不合格なら全体を却下;agent_memory/long_term/evolve/apply.py:昇格前スナップショット(data/snapshots/<timestamp>/)、適用後監査(data/logs/evolution_audit.jsonl)、rollback(snapshot_id)ロールバック;agent_memory/long_term/evolve/cycle.py:5ステップオーケストレーション(トリガー → ターゲット → 統合 → 検証 → プルーニング);models.py:MemoryEntryにretrieval_countフィールドを追加(ハイブリッド検索ヒットで +1、書き込みパスの近傍検索はカウントしない)。
M4b は layer3 評価セット + 進化メトリクス + 実受入を提供:
evals/datasets/layer3/:12 件のクロスセッション隠れ関連ケース(書籍の第3層「プロアクティブサービス」のプログラミングシナリオ改変: 事実と計画が異なるセッションにあり、正解するには両者の隠れた競合を能動的に提示する必要がある;各ケースに profile 常駐層記憶検索層詳細記憶を含み、rubric.essential に「隠れた関連を能動的に提示」項目を必ず含む);
evals/runners/metrics.py:ペア統計(McNemar 正確検定 + ペアブートストラップ利得区間、 純関数で scipy 依存なし、サンプル < 20 は「強い結論には不十分」と明示);evals/runners/e2e_eval.pyに--baselineを追加:同じケース群を空ストアでペア再実行、問題ごとの勝敗、 p 値、ホールドアウト利得区間を出力;さらに3つの進化メトリクスを埋め込む——活性化率(書き込んだ記憶が想起された割合)、 遵守率(判定者が判定根拠を想起記憶から確認したケースの割合)、ホールドアウト利得(記憶あり - baseline スコア差);実受入数値:layer3 記憶あり 91.67% vs baseline 0%(McNemar p=0.0010、n=12 は方向性の参考のみ); 回帰 layer1 100% / layer2 100% / prefix 88.89%;evolve クローズドループ実デモ(boundary 却下1回と merge 昇格 + ロールバック1回を含む)で consolidate の欠陥2件を露呈、AGENTS.md の未解決問題を参照。
M5 は人間によるレビュー対話ノード + 強制更新フックを提供:
config.pyにreview_gate(off / ask / strict、デフォルト ask:レビューキューにバックログがある場合のmemory_searchの 処置段階)とreview_turn_interval(デフォルト 3、フックのターン間隔)を追加、環境変数AGENT_MEMORY_REVIEW_GATE/AGENT_MEMORY_REVIEW_TURN_INTERVALで上書き;MCP ツールが5つから7つに拡張——新規
memory_review_list(保留詳細)とmemory_review_resolve(approve そのまま格納 / modify テキストを匿名化+評価ゲート通過後に格納 / discard 破棄);memory_searchにレビューゲートを追加(ask 段階は blocked でユーザー確認後に通過、strict 段階は一律拒読、off はブロックしない);memory_addはpending_review保留レビュー詳細を返す;蒸留プロンプトに「ユーザー確認資格」ハードルールを追加:assistant が一方的に提案し、ユーザーが明確に確認していない提案/計画/結論は沈殿させない;
scripts/memory_turn_hook.py:kimi-code Stop フック、セッションごとにターンをカウントし、N ターンごとにセッション終了をインターセプトして 蒸留指示を注入(材料 = 各ターンのユーザーメッセージ + 隣接する assistant 返信)、ユーザーレベル~/.kimi-code/config.tomlに登録済み。
M6 は HTTP 常駐サービス + スコープ規律を提供:
agent_memory/server/http_server.py:streamable-http 常駐サービス、デフォルトで 127.0.0.1:8765 のみにバインド (ループバックアドレスは自然に認証不要)、MCP エンドポイントに/SKILL.md(プロンプト層全文配布)と/bootstrap(新エージェント統合ブートストラップ指示)の2つの静的ルートを追加;相手エージェントはブートストラップ指示1つで統合可能、ファイルコピー不要;スコープ規律(共通ライブラリ、マルチエージェント・マルチプロジェクト混在):SKILL.md にスコープ選択ルールを追加(共通は global、 プロジェクトは repo:<名>、不明ならまずユーザーに確認)、
memory_addのスコープはデフォルトで global にフォールバックするが、返り値にscope_reminderリマインダーを添付;Windows 常駐運用:
scripts/start_http_server.cmd起動ラッパースクリプト(クラッシュ時自動リトライ最大3回、 3連敗でdata/state/http_server_FAILED.txt失敗マーカーを書き、ログはdata/logs/http_server.log)ログイントリガー計画タスク(登録スクリプト
scripts/register_task_s4u.ps1、管理者権限が必要)。
M7 は3層記憶(長期 / 作業 / 短期)+ 統一インターフェースを提供:
パッケージ構造移行:元の
store/ retrieve/ ingest/ evolve/ adapters/5つのサブパッケージをすべてagent_memory/long_term/に移行(ロジック変更ゼロ)、新規working/とshort_term/;agent_memory/working/:作業記憶(操作層、現在のタスク状態——目標/ToDo/決定/変数/メモ、 スコープごとに1つ、data/working/に保存)。書き込みは全置換、匿名化のみで評価ゲートなし;turn_watermark水位とstale_wmで状態が遅れているか判定;agent_memory/short_term/:短期記憶 transcript アダプタ層、エージェントのネイティブログ (例:kimi-code の wire.jsonl)をクリーンなターンシーケンスに解析、新規ファイルは作成しない;MCP ツールが7つから13個に拡張:新規
memory_wm_read/memory_wm_write/memory_wm_clear(作業記憶の読み書きクリア)、memory_context(常駐プロファイル + 作業記憶 + 想起を一度に組み立て)、memory_transcript_read(ターン読み取り、since_turn 増分)、memory_session_end(セッション終了処理:data/raw アーカイブ + 共同蒸留 + 完了済み ToDo のクリーンアップ、保留 ToDo は veto)。

LLM の設定(蒸留 / 対帳 / LLM 判定用)
蒸留書き込みパスには OpenAI 互換エンドポイントが必要、デフォルトは DeepSeek(https://api.deepseek.com、モデル deepseek-chat):
export AGENT_MEMORY_LLM_API_KEY=sk-...
# 可选覆盖:AGENT_MEMORY_LLM_BASE_URL / AGENT_MEMORY_LLM_MODEL
# 评估评委可单独配置(异源互审):AGENT_MEMORY_JUDGE_LLM_API_KEY 等キー未設定の場合、検索、手動書き込み、フィードバック、削除など LLM に依存しない機能は通常通り利用可能; 会話蒸留パスのみ呼び出し時にエラー(fail-closed)。
CLI 蒸留コマンド
会話([{role, content}, ...] の JSON ファイル)を完全な書き込みパイプラインでストアに格納:
uv run agent-memory distill --file conversation.json --scope repo:my-project \
--source kimi-code --session-id 2026-08-19-session
# 管线:蒸馏 → 评价门 → 对账;无法自动收敛的冲突会写入 data/review_queue/MCP server
起動:uv run python -m agent_memory.server.mcp_server(stdio)。

--layers 1,2で一度に実行、2つのプロセスに分けて各レイヤーを実行しない。
ルール降格モードは実際の蒸留品質を表すものではないため、正式な受入には実際の LLM を設定して再実行が必要。
M3 の使い方
LangGraph 統合
自作の LangGraph エージェントには3つの接続方法があり、重ねて使用可能:
from agent_memory.long_term.adapters.langgraph.store import AgentMemoryStore
from agent_memory.long_term.adapters.langgraph.tools import build_memory_tools
from agent_memory.long_term.retrieve.resident import build_system_context
from langgraph.prebuilt import create_react_agent
# 1) BaseStore:namespace 约定 ("memories", <scope>),put/search/delete 直接映射到记忆内核
store = AgentMemoryStore() # 配置走 AGENT_MEMORY_* 环境变量
store.put(("memories", "repo:myproj"), "db-choice",
{"content": "本项目数据库定为 SQLite,文件 data/app.db。", "confidence": "high"})
# 2) ReAct tool:recall_memories / save_memory 挂进 tools 列表
tools = build_memory_tools()
# 3) 常驻层:profile 类记忆渲染进 system prompt(预算是召回预算的一半)
prompt = "你是用户的编程助手……\n\n" + build_system_context("repo:myproj")
agent = create_react_agent(model, tools, prompt=prompt, store=store)完全な実行可能な例は examples/langgraph_demo.py(uv run python examples/langgraph_demo.py、
AGENT_MEMORY_LLM_API_KEY が必要)。
BaseStore の put は低レベル同期インターフェース:呼び出し側は精製済みの原子コンテンツを提供する必要があり、アダプタ層は 匿名化+評価ゲートルールを通過(指示内容は直接エラーを投げる)が、LLM 蒸留は行わない;save_memory ツールの 対帳は LLM なしの純ルールパス(近傍重複は NOOP、それ以外は ADD)、競合収束は M2 蒸留パイプラインを経由。
Skill 統合
skills/agent-memory/SKILL.md はプロンプト層で、ラップされたエージェント(Kimi Code / Claude Code)に
いつ検索、書き込み、フィードバックするかを教える。インストール方法(MCP server と併用):
Kimi Code:
skills/agent-memory/を~/.kimi-code/skills/agent-memory/にコピーまたはシンボリックリンク;Claude Code:
~/.claude/skills/agent-memory/にコピー;同時に上記 MCP 設定で
agent-memoryserver をマウントし、Skill 内のツール名(memory_search など)に実装を持たせる。
軌跡プレフィックス回帰評価
凍結コンテキスト(system + 注入済み記憶ブロック + ユーザー最新メッセージ)→ LLM が次のアクションを出力 → 判定者が 許容セットに含まれ、禁止セットに触れていないかを判定。4つの境界シナリオ(指示競合 / scope 漏れ / 低信頼度 / 注入耐性)+ 正常想起対照をカバー:
uv run python evals/runners/prefix_regression.py # 需 LLM key,无 key 整体跳过
uv run python evals/runners/prefix_regression.py --seeds 3 # 多种子报均值与区间
uv run python evals/runners/prefix_regression.py --no-cache # 禁用 LLM 响应缓存(默认开)429 レート制限は自動間隔リトライ;LLM レスポンスディスクキャッシュは e2e_eval と data/logs/llm_cache/ を共有。この評価にはルール降格モードはない(アクターの動作自体が被験対象)。
M4 の使い方
睡眠学習ループ(evolve)
# dry-run:只到提案为止,打印提案摘要,不验证、不应用
uv run agent-memory evolve --dry-run
# 完整循环:触发 → 整合 → 三档验证 → 通过则晋升(自动快照 + 审计)
uv run agent-memory evolve
# 只整理某个 scope
uv run agent-memory evolve --scope repo:my-repoトリガー条件(いずれか、閾値は AGENT_MEMORY_EVOLVE_* 環境変数で上書き):前回整理から7日超(EVOLVE_INTERVAL_DAYS)、新規エントリ50超(EVOLVE_NEW_ENTRIES_THRESHOLD)、レビューキューバックログ10超(EVOLVE_REVIEW_BACKLOG_THRESHOLD)。
整理が生成するのは提案(data/review_queue/evolution/<timestamp>/proposal.yaml)であり、直接書き換えではない:3段階検証(boundary / retention / safety)のいずれかが不合格なら却下、提案はアーカイブして人に委ねる;すべて合格して初めて昇格——昇格前に記憶層のスナップショット(data/snapshots/<timestamp>/)、昇格後に監査ログ(data/logs/evolution_audit.jsonl)を書き込む。ロールバックは agent_memory.long_term.evolve.apply.rollback(snapshot_id, settings, embedder) でスナップショットから記憶層を復元しインデックスを再構築。
M5 の使い方
人間によるレビュー(レビューキューの2つの対話ノード)
蒸留の不正出力、評価ゲートの低信頼度、対帳が収束しない競合はすべて data/review_queue/ に入り、人間の裁定を待つ。
レビューは2つの MCP ツールで完了:
memory_review_list:保留詳細を一覧表示(ソース、理由、内容);memory_review_resolve:裁定——approveそのまま格納 /modifyテキストを匿名化+評価ゲート通過後に格納 /discard破棄。裁定成功でキューファイルを削除;raw_record タイプの保留は直接格納不可。
レビューゲート(AGENT_MEMORY_REVIEW_GATE、デフォルト ask):キューにバックログがある場合の memory_search の動作——
ask は status=blocked を返しユーザー確認を待つ(acknowledge_pending=true で通過)、strict は一律拒読
(無人運用シナリオ)、off はブロックしない。memory_add の返り値には pending_review 詳細が含まれ、
エージェントは各項目をユーザーに報告し裁定を求めるべき(SKILL.md に対応フローあり)。
強制記憶更新フック
scripts/memory_turn_hook.py は kimi-code の Stop フック:セッションごとにターンをカウントし、
AGENT_MEMORY_REVIEW_TURN_INTERVAL(デフォルト 3)ターンごとにセッション終了をインターセプトし、蒸留指示を注入
(材料 = 各ターンのユーザーメッセージ + 隣接する assistant 返信)。ユーザーレベル
~/.kimi-code/config.toml に登録済みで、すべてのプロジェクトセッションに有効;他のホストはスクリプトを参照して自分でフックを接続可能。
M6 の使い方
HTTP 常駐サービス
stdio モードはホストが server を子プロセスとして起動し、セッションとともに生滅;HTTP モードは長期実行のローカルサービスで、 HTTP リクエストを送信できる任意のエージェントホストが URL を登録するだけで13個すべてのツールを取得:
uv run python -m agent_memory.server.http_server
# 默认监听 http://127.0.0.1:8765/mcp(只绑回环地址,天然免鉴权)
# 覆盖:AGENT_MEMORY_HTTP_HOST / AGENT_MEMORY_HTTP_PORTサービスには他に2つの静的ルートがある:/SKILL.md(プロンプト層全文)と /bootstrap(統合ブートストラップ指示)。
新エージェントの統合は /bootstrap の内容を与えるだけ:http://127.0.0.1:8765/mcp を登録
(トランスポートタイプ streamable-http)+ /SKILL.md を読んで従う、ファイルコピーは不要。
Windows 常駐(計画タスク)
scripts/start_http_server.cmd は起動ラッパースクリプト:異常終了時60秒待って再起動、最大3回;
3連敗で data/state/http_server_FAILED.txt 失敗マーカーを書き、ログは
data/logs/http_server.log。scripts/register_task_s4u.ps1 はログイントリガー計画タスクを登録
(S4U バックグラウンドモード、完全にウィンドウなし)、管理者権限が必要。両スクリプトは純 ASCII を維持する必要がある
(cmd.exe は .cmd を GBK で読み、PowerShell 5.1 は BOM なし .ps1 を ANSI で読む、非 ASCII は解析を壊す)。
M7 の使い方
統一コンテキスト組み立てと作業記憶
memory_context(scope, query?, k?, current_turn?) は3つのセクションを一度に組み立てる:常駐プロファイルブロック(長期記憶内の profile)
→ 作業記憶ブロック(現在のタスク状態)→ 想起ブロック(query を渡した場合のみ長期記憶を検索)。現在のタスク状態の日常メンテナンスは
3つの作業記憶ツールで行う:
memory_wm_write(scope, goal?, decisions?, variables?, todos?, notes?, turn_watermark?): 全置換書き込み(マージではなく、渡されなかったフィールドはクリアされる)、匿名化のみ、評価ゲートなし;memory_wm_read(scope, current_turn?):読み取り + 鮮度判定(stale_wm=trueは現在のターン数が 作業記憶のturn_watermark水位を超えていることを意味——「この状態は何ターン目まで更新済みか」、状態が遅れている可能性);memory_wm_clear(scope):クリア(冪等、存在しない場合もエラーではない)。
作業記憶は操作層のドラフト:完了項目の結論は長期記憶に蒸留(memory_add または下記 memory_session_end)して初めて
沈殿したと見なされる。
セッションログ読み取りとセッション終了処理
memory_transcript_read(log_path, adapter?, since_turn?) はエージェントのセッションログ(例:kimi-code の
wire.jsonl、ファイル名で形式を自動検出)をクリーンなターンシーケンス(user/assistant/tool)に解析;since_turn
は作業記憶の水位と組み合わせて増分読み取り(水位以降のターンのみ返す)。
memory_session_end(scope, conversation_json?|log_path?, ...) はセッション終了の標準処理で、一度に完了:
原文をアーカイブ(data/raw/、追記のみで書き換えなし)→ 共同蒸留(会話 + 作業記憶スナップショットを参照コンテキストとして)→ 作業
記憶の完了済み ToDo をクリーンアップ。作業記憶に保留 ToDo がある場合は veto(アーカイブ/蒸留/クリーンアップすべて実行しない)、終了確認は
force=true を渡す。これは N ターンごとのローリング蒸留フックと二重トラックの役割分担:フックは途中クラッシュによる損失を防ぐ保険、session_end
は標準終了処理を行う。
3つのアーキテクチャレッドライン
AGENTS.md を参照。要するに:データ3層分離(raw は追記のみ、memory は唯一の真実ソース、index は再構築可能で手動変更禁止);書き込みは匿名化→蒸留→対帳のゲートを通過必須;evals / rubric / リリース閾値 / 監査ログはエージェントによる自己変更を禁止。

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full behavioral disclosure. It reveals the distillation pipeline for conversations, desensitization/reconciliation for single content, server-side auto-serialization for arrays, error behavior for invalid types, and default scope fallback. This is strong behavioral context beyond a simple 'write' action, though it stops short of describing return values or side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a compact, logically organized paragraph with no filler. It front-loads the core action, then covers format, scope, and default behavior in sequence. Every sentence contributes essential information, making it highly efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description covers purpose, key parameter semantics, and processing behavior well. The remaining gaps—such as the exact meaning of optional parameters like entry_id or session_id—are minor because those parameters are either inferable or have defaults. The description is close to complete for an agent to successfully call the tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero parameter descriptions, so the description must compensate. It explains the two most complex parameters: conversation_json (JSON string or array, auto-serialization) and scope (global/repo/agent conventions), and mentions content processing. Other parameters like memory_type, confidence, and source remain undocumented, but their names and defaults make them less ambiguous. The description covers the parameters that truly need clarification.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool writes memory, using the specific verb '写入记忆' (write memory), and distinguishes it from sibling tools like memory_update and memory_forget by nature. It also explains the processing pipeline for conversation vs single content, which adds further specificity beyond a generic 'write' operation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides concrete guidance on how to invoke the tool: recommended conversation_json format, explicit scope value conventions (global, repo:<name>, agent:<name>), and default fallback behavior. It does not explicitly state when to use this tool instead of alternative memory tools, but the detailed usage context is clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

With no annotations provided, the description carries the full disclosure burden and delivers substantial behavioral detail: the fixed assembly order, conditional recall on query, and the review-gate state machine (status=blocked, retry flag, prerequisite cleanup via review tools). The blocked/retry workflow is non-obvious and not inferable from the schema. It stops short of stating whether the operation has side effects or how a successful response is structured.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two dense sentences with the primary assembly behavior front-loaded before the conditional review-gate flow. Every clause carries information — assembly blocks, ordering, query conditionality, and the blocked-state retry procedure. It is slightly dense with domain terminology but efficient overall with no filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has no annotations, no output schema, and no parameter descriptions, so the description must cover both return values and parameter semantics. It explains the blocked status and retry path but never describes the success response shape, and leaves scope (required), k, and current_turn undefined. This is insufficient for an agent to invoke the tool reliably on the first attempt.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate, but it only explains two of five parameters: query (triggers recall) and acknowledge_pending (retry after user confirmation). The required parameter scope is never defined at all, and k (despite its default of 5) and current_turn are also left unexplained. An agent cannot determine valid scope values or what k controls, which is a critical gap for the only required parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific verb ('统一组装注入上下文' — uniformly assemble and inject context) and names the exact resources: resident profile block, working memory block, and recall block, with their concatenation order. This composition detail differentiates it from siblings like memory_wm_read or memory_search that handle only individual memory pieces. It doesn't explicitly name a sibling it is not, but the assembly semantics make the tool's role clear.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives explicit conditional guidance: recall is only performed when query is passed ('传 query 才检索历史记忆'). It also specifies a concrete edge-case workflow with named alternatives — when status=blocked, retry with acknowledge_pending=true or first process pending items via memory_review_list / memory_review_resolve. It does not contrast normal-use selection against siblings like memory_search or memory_wm_read, but the blocked-state routing is explicit and actionable.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
memory_feedbackB

| Name | Required | Description | Default |
|---|---|---|---|
| note | No | ||
| helpful | Yes | ||
| memory_id | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It reveals the action of adjusting confidence and the conditional manual review queue, adding context beyond the verb. However, it does not disclose whether the operation is a write, if it is reversible, return format, or error handling, leaving notable gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise sentence, front-loaded with the action. It is efficient and easy to scan, though it lacks structure for parameter details. It earns a high score for conciseness, not for completeness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 3 parameters, no output schema, and no annotations, the description should compensate by explaining parameter semantics and usage context. It explains the main behavior but omits parameter meanings and when to use this tool over siblings, leaving the agent under-informed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description does not explain the parameters memory_id, helpful, or note. The description implies 'helpful' relates to usefulness but never explicitly defines each parameter, leaving agents to infer meaning from types and names alone.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific action (feedback on memory usefulness), the resource (memory), and the outcome (adjust confidence, possible manual review). This clearly differentiates it from siblings like memory_add, memory_update, and memory_review_resolve, which have different purposes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool is for providing feedback on memory usefulness, but does not explicitly state when to use it versus alternatives like memory_review_resolve or memory_forget. No when-not-to-use conditions or alternative routing are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
memory_forgetB
删除一条记忆(记忆层与索引同步删除)
| Name | Required | Description | Default |
|---|---|---|---|
| memory_id | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds a useful behavioral detail: the memory layer and index are deleted synchronously, ensuring consistency. However, with no annotations at all, it does not disclose irreversibility, permission requirements, or what happens to related feedback/review data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is one short sentence, efficient and easy to scan. The parenthetical adds a relevant operational detail without bloating the text, though a bit more context could be added.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a destructive operation with no annotations and no output schema, the description is under-specified. It does not mention irreversibility, how to retrieve memory_id, or any side effects on related data, leaving an agent to guess critical usage constraints.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% and the description does not mention memory_id at all. It simply says 'delete a memory' without explaining that the memory_id parameter identifies the target or how to obtain it, leaving the schema to bear all meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb '删除' (delete) and a clear resource ('一条记忆' - one memory), and the parenthetical clarifies it removes both the memory layer and its index. This clearly distinguishes it from siblings like memory_search or memory_wm_clear.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is given on when to use this tool versus alternatives. It does not state that this is for permanent removal of a specific memory, nor does it mention prerequisites such as obtaining a memory_id from memory_search or memory_review_list.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
memory_review_listA

| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. The description only states that it lists items and the fields returned; it does not explicitly state that it is read-only or lacks side effects. While the name suggests a list operation, the description does not communicate this behavioral guarantee, leaving the agent to infer safety.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, focused sentence that front-loads the action and resource, then specifies the returned fields. There is no extraneous information, and it is appropriately concise for a list operation.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple, but the description omits how to identify specific items for later resolution (e.g., an ID field) and does not mention any ordering or pagination behavior. Without an output schema, an agent may need more context to use the results with sibling tools like memory_review_resolve, which would require some reference to individual items.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has no parameters, so schema description coverage is trivially 100%. The baseline for 0 parameters is 4, and the description does not need to add parameter meaning because there are none. It provides no extra parameter information, which is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses the verb '列出' (list) with a specific resource '人工复核队列的全部待办' and enumerates the returned fields (content, reason, queue file name). This clearly distinguishes it from siblings like memory_review_resolve, which handles resolution, and memory_search, which is general search.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies this tool is for viewing the review queue but does not explicitly state when to use it over alternatives, such as when to use memory_review_resolve after listing. There is no mention of prerequisites, exclusions, or the relationship with sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
memory_review_resolveA
裁决一条复核待办:approve 确认入库 / modify 以 new_content 替换正文后入库 / discard 丢弃。queue_file 取 memory_review_list 返回里的 file 字段
| Name | Required | Description | Default |
|---|---|---|---|
| action | Yes | ||
| queue_file | Yes | ||
| new_content | No |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full disclosure burden. It accurately conveys the side effects of each action: approve persists, modify replaces content before persisting, and discard drops the item. It also explains the provenance of queue_file. However, it does not disclose whether the queue item is consumed after resolution or whether new_content is mandatory for the modify action, leaving minor gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single compact sentence that lists the actions and their meanings, followed by a short clarification of where queue_file originates. Every clause adds necessary information without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the core workflow, parameter sourcing, and action semantics, which is sufficient for an agent to invoke the tool correctly. It omits return values, explicit requirement of new_content for modify, and post-resolution queue state, but these are secondary for a narrowly scoped resolution tool. Given the lack of an output schema, this is reasonably complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It fully documents all three parameters: action enumerates the valid values (approve/modify/discard), queue_file is tied to the output of memory_review_list, and new_content is defined as the replacement body for modify. This resolves the ambiguity left by the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific verb (裁决/adjudicate) and resource (复核待办/review todo), then enumerates the permissible actions (approve, modify, discard), making the tool's purpose unmistakable. It also distinguishes itself from the sibling memory_review_list by focusing on the resolution step rather than the listing step.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly tells the agent that queue_file comes from the return of memory_review_list, effectively positioning this as the follow-up to that tool. It names the source of a key parameter and implies a list-then-resolve workflow, though it does not formalize when-not-to-use or list alternative tools for this specific action.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
memory_searchA
检索历史记忆,返回注入用 XML 块与结构化命中列表。scope 自动归一化(下划线等旧写法折叠为连字符),非法 scope 当场报错而非静默返回空。复核队列有积压时按 review_gate 配置处置:返回 status=blocked 表示被复核门拦截,需先向用户确认(用户同意后以 acknowledge_pending=true 重试,或先用 memory_review_list / memory_review_resolve 处理待办)
| Name | Required | Description | Default |
|---|---|---|---|
| k | No | ||
| query | Yes | ||
| scope | No | global | |
| acknowledge_pending | No |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description becomes the sole source of behavioral disclosure. It discloses scope normalization, immediate errors on illegal scope (rather than silent empty results), and the review-gate blocking behavior with status=blocked and the resolution path. This is substantial, though it doesn't cover aspects like authentication or rate limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is structured with a clear first sentence stating purpose and output, followed by two sentences explaining error handling and the review-gate flow. It's detailed but not verbose, and every sentence carries relevant operational information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Since there is no output schema, the description must convey return structure, and it does: it mentions the XML block and structured hit list, plus the status=blocked variant. It also covers edge cases (illegal scope, review backlog) and provides the retry/alternative paths. For a search tool of this complexity, this is adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It explains the behavior of 'scope' (normalization) and 'acknowledge_pending' (used in retry after confirmation), which are the non-obvious parameters. 'query' and 'k' are self-explanatory from their names and defaults, so the description adds sufficient meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific verb ('检索' = retrieve), a resource ('历史记忆' = historical memory), and what it returns (XML block and structured hit list). This clearly distinguishes it from sibling tools like memory_review_list or memory_add, which serve different purposes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives explicit guidance on handling the blocked status: after user confirmation, retry with acknowledge_pending=true, or use memory_review_list / memory_review_resolve to process pending items. This tells the agent when to use alternatives, though it doesn't explicitly say 'use this tool when you need to search' vs. other contexts.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
memory_session_endA
会话结束收尾编排:归档原文(data/raw,只追加不改写)+ 联合蒸馏(对话提炼长期记忆,工作记忆快照作参考上下文,冲突会更新旧条目) + 清理工作记忆里已完成的待办。工作记忆有未完成任务时会 veto(status=vetoed,归档/蒸馏/清理都不执行),确认结束请以 force=true 重试。对话材料二选一:conversation_json([{role, content}, ...] 的 JSON 字符串或数组,agent 中立推荐,优先使用)或 log_path(agent 会话日志路径,走日志适配器解析,adapter 可缺省按文件名 自动识别)。未配置 LLM 时只归档不蒸馏(status=archived_only)

| scope | Yes | ||
| source | No | mcp | |
| adapter | No | ||
| log_path | No | ||
| session_id | No | ||
| conversation_json | No |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses detailed behavior: append-only archiving, conflict updates during distillation, veto with status=vetoed and force override, archived_only fallback, and adapter auto-detection. This goes well beyond minimal expectations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single dense paragraph that covers all key points without fluff. It is front-loaded with the main orchestration, then veto, then material options. However, it could be improved with bullet points for readability, but it still earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (7 params, no output schema, no annotations), the description is quite complete. It explains the core flow, edge cases, and material options. The main shortfalls are undocumented parameters and lack of return-value details, but these are partially offset by the thorough behavioral coverage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It explains conversation_json, log_path, adapter, and force thoroughly, but omits scope, source, and session_id entirely. These are not self-evident from the schema, leaving gaps for the agent.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: orchestrating session-end wrap-up with archiving, distillation, and cleanup. It distinguishes itself from siblings (e.g., memory_transcript_read, memory_add) by focusing on the end-of-session flow, making its role unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It provides strong context on when to use the tool (at session end) and explains veto/force behavior for incomplete tasks, plus fallback to archived_only without LLM. However, it does not explicitly contrast with sibling tools like memory_wm_write or memory_add, and the 'agent 中立推荐' note is more about parameter selection than tool selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
memory_transcript_readA
读取 agent 会话日志(如 kimi-code 的 wire.jsonl),解析成干净的轮次序列(user/assistant/tool,含轮次编号与时间戳)。纯读不写。配合工作记忆水位做新鲜度补偿:传 since_turn=<memory_wm_read 返回的 turn_watermark> 只返回水位之后的新轮次,据此判断要不要 wm_write 刷新工作记忆。adapter 缺省按日志文件名自动识别,识别不了需显式指定(可用列表见报错信息);日志不存在会报错
| Name | Required | Description | Default |
|---|---|---|---|
| adapter | No | ||
| log_path | Yes | ||
| since_turn | No |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations are absent, so the description carries the full burden. It discloses the tool is read-only ('纯读不写'), describes the output structure (turn sequences with numbering and timestamps), explains the adapter fallback behavior (auto-detect or explicit, with error message listing available adapters), and notes that missing logs will cause an error. This is thorough behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is structured into a logical flow: main purpose, usage pattern with since_turn, then adapter behavior and error conditions. It is four sentences but dense with information, front-loaded with the core function and then branching into usage details. It is not overly verbose for the complexity it covers.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (read logs, parse turns, support filtering, adapter handling) and the absence of annotations, the description covers essential aspects: parameters, usage integration with wm_read/wm_write, error handling (missing log, adapter detection), and output format ('轮次序列(user/assistant/tool,含轮次编号与时间戳)'). No critical gaps for an agent to call it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must explain all three parameters. It does: log_path is implied ('读取 agent 会话日志'), adapter behavior is explained ('adapter 缺省按日志文件名自动识别,识别不了需显式指定'), and since_turn is clearly defined ('传 since_turn=... 只返回水位之后的新轮次'). Meaning is fully compensated beyond the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific verb ('读取' = read), a specific resource ('agent 会话日志' = agent session logs), and the output transformation ('解析成干净的轮次序列' = parse into clean turn sequences). It also explicitly distinguishes itself from siblings by emphasizing '纯读不写' (pure read, no write) and unique functionality (transcript reading) not covered by other tools like memory_wm_read or memory_search.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context for use: it explains the integration with memory watermark ('配合工作记忆水位做新鲜度补偿') and explicitly references sibling tools memory_wm_read and memory_wm_write, showing how since_turn should be used. It also covers adapter auto-detection behavior and error conditions. It lacks an explicit 'when not to use' clause but the context is sufficiently clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
描述提到更新内容会经过脱敏与评价门,揭示了一个重要的处理流程,但未说明失败行为(如门拒绝时返回什么)、权限要求、可逆性或副作用。由于无注解,描述承担全部责任,但此处提供的信息有限,仅部分披露了行为。
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
一句话完成,无冗余,动作前置,括号补充关键流程约束。紧凑且信息优先,符合高效结构要求。
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
无输出schema,无注解,且为变更操作,但描述未说明返回内容、错误处理、副作用(如修改是否不可逆),也未说明通过门失败时的行为。对于调用者而言,信息不足以做出正确调用决策,完整性不足。
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
schema描述覆盖率为0%,参数名称和类型是唯一信息。描述未对memory_id或new_content增加任何额外语义,如格式、长度限制、示例或注意事项。描述仅重复了'正文'概念,对参数理解帮助有限。
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
描述明确给出具体动作'更新'和资源'记忆的正文',并附带脱敏与评价门的处理提示,使工具用途清晰且与其他记忆操作(如添加、删除)区分开来。即使未命名兄弟工具,名称和描述已足够明确。
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
未提供任何使用时机或与其他工具的对比。没有说明何时应使用更新而非添加或删除,也没有提及前置条件(如记忆必须存在)。仅凭工具名称和描述推断用途,缺乏明确指导。
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
memory_wm_clearA
清空一个 scope 的工作记忆;本就不存在时返回 already empty,不算错误
| Name | Required | Description | Default |
|---|---|---|---|
| scope | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses that clearing a non-existent scope returns 'already empty' rather than an error, which is a key behavioral nuance. While it does not elaborate on side effects or permissions, this is sufficient for a simple clear operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-structured sentence that front-loads the core action and efficiently includes the critical edge case. There is no redundancy or unnecessary detail.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one parameter and a clear action, the description covers the primary behavior and a notable edge case. It is slightly lacking in defining 'scope' and specifying the success return value, but these are minor given the tool's minimal complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% and the tool description does not explain what 'scope' refers to or what valid values it accepts. The agent is left without guidance on this essential parameter, and the description fails to compensate for the missing schema documentation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a clear verb '清空' (clear) and a specific resource 'scope 的工作记忆' (working memory of a scope), explicitly distinguishing this from sibling tools like memory_wm_read and memory_wm_write. The edge case about returning 'already empty' further clarifies its purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context that this tool operates on a scope's working memory, which makes its usage obvious given the sibling set. It does not explicitly name alternatives or exclusions, but the action is unambiguous and no conflicting tools exist in the visible sibling list.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
memory_wm_readA
读取一个 scope 的工作记忆(当前任务状态:目标/待办/决策/变量/备注),返回渲染好的注入块与结构化字段。scope 自动归一化,非法当场报错。传 current_turn 时返回 stale_wm 表示工作记忆是否可能滞后(当前轮次超过已更新到的轮次水位),滞后可考虑 wm_write 刷新
| Name | Required | Description | Default |
|---|---|---|---|
| scope | Yes | ||
| current_turn | No |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses automatic scope normalization, immediate errors on invalid scope, the stale_wm flag when current_turn is provided, and the return format (rendered injection block + structured fields). It also hints at the refresh path via wm_write. This is comprehensive for a read tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the primary purpose and then adding the advanced staleness detail. Every sentence adds value, no fluff. It is well-structured and easily parsed by an agent.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a read tool with only 2 parameters and no output schema, the description covers the return format, error handling, normalization behavior, and the staleness mechanism. An agent has enough context to invoke it correctly and interpret results without additional information.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It explains both parameters: 'scope' is the working memory scope to read and is normalized automatically; 'current_turn' is used to trigger staleness detection and returns stale_wm. This adds meaningful semantics beyond the schema's bare names and types, though it doesn't detail value formats or ranges.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description starts with a specific verb '读取' (read) and a clear resource: 'scope 的工作记忆' (working memory of a scope), and enumerates its contents (goals/todos/decisions/variables/notes). It clearly differentiates from siblings like memory_wm_write (write) and memory_wm_clear (clear) by specifying the read operation. This is a precise, unambiguous purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives clear context: use this tool to read a scope's working memory for current task state. It also mentions when to consider using a sibling (wm_write refresh if stale_wm indicates lag), which implies the alternative when the data is stale. However, it does not explicitly contrast with other read/search tools like memory_search or state when NOT to use it, so it's not a full 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully carries the behavioral burden. It discloses the full-replacement semantics (destructive but essential), text desensitization, the pass-through of todo items as imperative sentences (bypassing evaluation gate), and the turn_watermark retention behavior. These are the key behavioral traits an agent needs to know before calling.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is compact yet information-dense. The most critical warning (full replacement) is front-loaded, and every sentence adds necessary context—no filler. It efficiently covers the trickiest aspects of the tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a 7-parameter write tool with no annotations and no output schema, this description provides the essential operational knowledge: the destructive replacement behavior, the two tricky parameters (todos and turn_watermark), and the text-processing nuance. It is complete enough for an agent to call it correctly, covering the high-risk elements thoroughly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate for parameter meaning. It thoroughly explains the todos parameter (two accepted formats with status semantics) and turn_watermark (current dialogue turn, default retention). It also implies that all text fields undergo desensitization. It does not delve into goal, notes, decisions, or variables, but the general replacement rule covers them, so it adds significant meaning beyond the raw schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('写' write) on the '工作记忆' (working memory, current task state), which is a specific resource. This distinguishes it from sibling memory tools like memory_add or memory_update, which likely target long-term memory. The scope is unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives clear context (writing current task state) and explicit critical usage instructions (full replacement, not merge; fields not passed are nulled). However, it does not explicitly contrast with alternative memory tools (e.g., when to use this vs memory_update or memory_add), so it lacks exclusions. Still, the context is clear enough for correct selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 13 tools
Each tool maps to a distinct resource and action: long-term memory CRUD, working memory read/write/clear, review queue list/resolve, unified context assembly, transcript reading, and session-end orchestration. Even memory_context is clearly an orchestration layer over memory_search and memory_wm_read, not a competing implementation. The only mild overlap is transcript_read versus session_end log parsing, but one is read-only and the other is a write pipeline.
All tools share the memory_ prefix and snake_case, but the pattern varies slightly: base operations use verb-only suffixes like memory_search and memory_add, while subarea operations use noun_verb suffixes like memory_wm_read and memory_review_resolve. memory_context and memory_feedback are noun-oriented rather than strict verb_noun. Overall the convention is still predictable and readable.
13 tools is well-scoped for a memory server covering long-term memory, working memory, review queue, context assembly, transcript access, and session-end orchestration. Each tool has a distinct lifecycle purpose, and none feels redundant or missing as a surface-level feature.
The surface covers full CRUD for long-term memories, working-memory read/write/clear, review workflow, context assembly, and session-end archival/distillation. The review-gate blocked/acknowledge and session-end veto/force flows prevent dead ends. The only arguable gap is dedicated profile management, but profiles are exposed through memory_context and updatable via memory_add/memory_update.
