+

+ Mnemon 把 canonical state 放在 .mnemon，让 host agent 读取 INSTALL.md 后把 recall、observe、reflect、curate 四类 semantic hooks 挂载到自己的生命周期。Host 仍拥有 LLM loop、工具、权限和 UI；harness 只提供技能、记忆、hook、报告、治理和可选 maintenance runner。 +

架构展示只保留四条主线：安装挂载、记忆循环、技能演进、评测风控。其他 hook 和 runner 都是这些路径的实现细节。

+
+
+
+
+ +
+
+
+

Working Memory / Long-Term Memory Consolidation

+

Working Memory 是直接进入 prompt 的 Markdown；Long-Term Memory 由 Mnemon Store 和 Skills 承载；Dreaming Jobs 负责巩固、降级、晋升和技能候选。

+
+
+
+
+ + + + + + + + +
+ +
+
+
+
+
+
+ +
+
+
+

Skill Self-Evolution

+

Skill 的生产有三个入口：用户声明、agent 询问确认、后台 review；curator 负责跨时间治理 self-authored skills。

+
+
+
+
+ + + + + + + + + + + +
+ +
+
+
+
+
+
+ +
+
+

Hook Mount Explorer

+

.mnemon 是 canonical；host agent 通过 instruction、skill、hook、scheduler 四类表面挂载 semantic hooks。

Memory Loop MVP

+

第一版只实现一个清晰的记忆闭环：HostAgent 通过 hook 获得时机，通过 Markdown guide 做判断，通过 memory_get / memory_set / dreaming subagent 调用具体协议，最终在 MEMORY.md 与 Mnemon 之间完成在线读写和离线巩固。

+
+ +
+
+ +
+
+
+

System Components

+

这里先说明哪些东西是系统主体，哪些只是安装、触发、协议或维护资产。

+
+ +
+
+
Three Core Parts
+
+
+ HostAgent +

宿主 Agent 的核心引擎。它运行任务、接收 hook 注入，并根据 GUIDE.md 判断是否加载 skill 或启动 subagent。

+
+
+ MEMORY.md +

工作记忆主体。Prime 直接把它加入 system prompt；memory_set.md 负责在线维护它。

+
+
+ Mnemon +

长期记忆主体。mnemon binary 通过 brew 安装；memory_get.md 和 dreaming subagent 通过协议调用它。

+
+
+
+ +
+
Maintained Assets
+
+
+ Guide + setup +

GUIDE.md 说明何时读写记忆；Claude Code setup scripts 负责把 hook、skill、subagent 挂载到宿主。

+
+
+ Four hooks +

Prime、Remind、Nudge、Compact 只负责触发时机，不承载记忆协议。

+
+
+ Two skills +

memory_get.md 绑定 Mnemon recall；memory_set.md 绑定 MEMORY.md 编辑规则。

+
+
+ One subagent +

dreaming subagent 负责维护任务：巩固、压缩、丢弃和长期写入。

+
+
+
+
+
+ +
+
+ Guide 只定义判断 +

GUIDE.md 只回答“何时读记忆、何时写记忆、什么值得保留”，不直接绑定 MEMORY.md 或 Mnemon。

+
+
+ Skill 绑定协议 +

memory_get.md 负责把“读记忆”落到 Mnemon recall；memory_set.md 通过 MNEMON_MEMORY_LOOP_DIR 定位并 patch MEMORY.md。

+
+
+ Dreaming 做巩固 +

Dreaming 不是普通 hook。它是被 spawn 的维护 subagent，先写 Mnemon，再整理 MEMORY.md。

+
+
+ +
+
+

Mnemon provides durable memory, a stable memory +protocol, and lifecycle reminders that help the runtime use memory across +sessions. + +```text +Runtime does the work. +Mnemon preserves experience, recalls experience, and constrains the memory protocol. +``` + +The harness should stay simple: + +- **Skill first.** The agent learns Mnemon through markdown instructions and + command examples. +- **Guideline driven.** The agent receives one memory policy that explains when + to recall, remember, link, forget, or do nothing. +- **Hook assisted.** Four lifecycle reminders keep the guideline active at the + right moments. +- **Protocol constrained.** The agent makes semantic decisions; Mnemon provides + deterministic commands, structured output, provenance, deduplication, and + lifecycle operations. +- **Markdown evolved.** Stable experience can become reviewed markdown assets: + skills, guidelines, install notes, rules, contracts, or eval cases. + +## Non-Goals + +Mnemon should not become: + +- a full agent runtime +- a workflow engine +- a large adapter framework +- an automatic prompt-injection system +- an append-only memory dump +- a vector database wrapper +- a self-modifying agent without review + +Different runtimes do not need a custom Mnemon adapter before they can use the +harness. If a runtime can read instructions, run commands, and optionally attach +hooks or rules, it can install Mnemon by following this document. + +## Harness Shape + +The harness has four conceptual assets. + +| Asset | Purpose | +|---|---| +| **Mnemon binary** | Executes deterministic memory operations through `remember`, `recall`, `link`, and lifecycle commands | +| **Skill** | Teaches the agent what commands exist and how to call them | +| **Guideline** | Teaches the agent when memory is useful, what is worth writing, and how to avoid noise | +| **Hooks** | Remind the agent to apply the guideline at session start, task start, task end, and compaction | + +These assets can be installed as skill files, rules, system instructions, +plugin docs, hook scripts, or any runtime-specific equivalent. The installation +format is less important than preserving the behavior. + +## Markdown Contract + +The durable harness layer should be mostly markdown. A runtime-specific adapter +is optional convenience, not the core design. + +The canonical installation package should be expressible as three readable +files: + +| File | Primary Reader | Responsibility | +|---|---|---| +| `SKILL.md` | Agent | Command syntax, examples, available operations, output interpretation, and guardrails | +| [`INSTALL.md`](INSTALL.md) | Agent or human installer | How to install the skill, guideline, and four hook phases in the target runtime | +| [`GUIDELINE.md`](GUIDELINE.md) | Agent | Memory judgment: when to recall, remember, link, forget, supersede, or skip | + +This `HARNESS.md` is the design source of truth. `INSTALL.md` and +`GUIDELINE.md` are the installable runtime artifacts derived from it. They +should stay small enough for an agent to read in one pass. + +### Why This Shape + +Modern agent systems already treat markdown as executable operating context: +project instructions, skills, rules, hooks, slash commands, and memory summaries +are all plain text assets that the model can read and adapt to. Mnemon should +lean into that pattern instead of creating a heavy adapter layer for every +runtime. + +The important boundary is: + +```text +Markdown teaches behavior. +Hooks place reminders at lifecycle boundaries. +Mnemon executes deterministic memory commands. +The agent decides when memory is useful. +``` + +This keeps the system portable. Codex, Claude Code, OpenClaw, and future +agent runtimes can install the same conceptual harness through their own native +instruction mechanisms. + +### `SKILL.md` + +The skill is the capability surface. It should answer: + +- What is Mnemon? +- Which commands exist? +- What are the common command patterns? +- How should the agent read structured output? +- What are the hard guardrails? + +The skill should not carry the full memory policy. That belongs in +`GUIDELINE.md`. A skill that becomes too philosophical will be harder to reuse +across runtimes. + +### `INSTALL.md` + +The install guide is an agent-facing procedure. The target agent reads it and +maps the harness onto its own runtime: + +- install or verify the `mnemon` binary +- install `SKILL.md` into the runtime's skill/rule mechanism +- install `GUIDELINE.md` into the runtime's durable instruction mechanism +- add four hook phases when the runtime supports hooks +- fall back to persistent rules when hook support is absent +- verify the installation with a recall/writeback/no-op checklist + +`INSTALL.md` should describe what each hook phase must accomplish, not require +one hard-coded adapter implementation. Runtime-specific snippets are examples, +not the architecture. + +### `GUIDELINE.md` + +The guideline is the memory constitution for the agent. It should contain: + +- recall triggers and skip conditions +- durable write criteria +- provenance expectations +- link and supersede policy +- store/namespace isolation policy +- markdown self-evolution policy +- safety rules for secrets, prompt injection, stale memories, and noisy writes + +The guideline should be installed where the agent can consult it at session +start and before memory-sensitive decisions. It may be included directly in a +runtime instruction file, referenced by a skill, or injected by a lightweight +prime hook. + +## Memory Loop + +The memory loop is advisory, not mandatory. + +```text +Prime -> Recall decision -> Work -> Writeback decision -> Remember/link/forget -> Future task +``` + +The loop is memory-driven only when recall changes the current work and +writeback improves future work. Merely calling `recall` or `remember` is not +enough. + +## Four Hook Phases + +Install four hook phases when the runtime supports lifecycle hooks. If the +runtime does not support hooks, encode these phases as persistent rules and ask +the agent to self-check them at the same moments. + +| Phase | Typical Runtime Event | Purpose | Must Not Do | +|---|---|---|---| +| **Prime** | Session start / agent bootstrap | Load the Mnemon skill, this guideline, active store info, and memory stance | Bulk inject historical memories | +| **Remind** | User prompt submit / before task planning | Remind the agent to decide whether recall is useful for this task | Automatically recall every prompt | +| **Nudge** | Stop / after response | Remind the agent to decide whether any durable insight should be written back | Force every response into memory | +| **Compact** | Before context compaction | Preserve critical continuity before context is lost | Save the full conversation mechanically | + +Hook output should be short, natural-language, and easy for the agent to ignore +when memory is irrelevant. Hooks are cognitive affordances, not controllers. + +### Prime + +Prime establishes memory orientation. + +It should tell the agent: + +- Mnemon is available. +- The agent should use the Mnemon skill for command syntax. +- This harness guideline defines when memory is useful. +- The active store or namespace should be respected. +- Historical memory should be recalled only when relevant to the current task. + +### Remind + +Remind happens before the agent starts a task. + +It should ask the agent to consider recall when the task may depend on: + +- prior user preferences +- prior project decisions +- architecture conventions +- repeated failures or fixes +- deployment or environment facts +- previous unfinished work + +For trivial, local, or self-contained tasks, the agent can skip recall. + +### Nudge + +Nudge happens after the agent finishes a task. + +It should ask the agent whether the session produced durable knowledge worth +future reuse. The agent should write memory only when the insight is likely to +matter later. + +### Compact + +Compact happens before context compression. + +It should preserve only critical continuity: + +- open decisions +- user preferences that changed the work +- unresolved blockers +- important implementation facts +- commands or workflows that future agents must repeat or avoid + +## Memory Guideline + +The guideline is the behavioral policy every agent should follow. + +### Recall + +Recall when prior experience can plausibly change the current task. + +Good recall triggers: + +- The user refers to previous work, a prior decision, or an established + preference. +- The task touches architecture, release, deployment, integrations, or long-lived + project conventions. +- The agent is resuming after a long gap or context compaction. +- The task is likely to repeat a known failure mode. +- The user asks for consistency with prior style, strategy, or policy. + +Weak recall triggers: + +- A simple one-off command. +- A purely local code edit with clear current context. +- A question answered completely by the visible repository or current prompt. + +Recall results are evidence, not authority. Current user instructions, current +repository state, and verified sources override stale memory. + +### Remember + +Remember only durable insights. + +Good memory candidates: + +- stable user preferences +- project conventions +- architecture or product decisions +- repeated failure modes and fixes +- non-obvious setup or deployment facts +- constraints that future agents should respect +- decisions that supersede older decisions + +Poor memory candidates: + +- secrets, credentials, tokens, or private data +- transient progress updates +- raw conversation logs +- unverified assumptions +- facts that are already obvious from source files +- noisy implementation details unlikely to matter again + +Each durable write should include enough provenance for a future agent to judge +whether the memory still applies. + +Recommended provenance: + +- `source`: user, agent, system, repo, docs, command output +- `source_ref`: file path, command, issue, PR, conversation, or hook phase +- `reason`: why this is worth remembering +- `confidence`: how reliable the insight is +- `evidence`: concrete supporting reference when available +- `scope`: project, user, runtime, or global + +### Link + +Link memories when the relationship is useful for future recall. + +Useful links: + +- a decision supersedes another decision +- a failure is caused by a specific setup or dependency +- a preference applies to a project or runtime +- a workflow depends on a tool, file, or environment +- two memories should be recalled together + +Do not create links just because two memories are vaguely similar. + +### Forget And Supersede + +Memory must evolve. + +When a memory becomes outdated, prefer superseding or soft deletion over adding +another conflicting memory. A future agent should be able to tell which decision +is current. + +Use lifecycle operations when: + +- a stored decision is now wrong +- a preference changed +- an implementation detail no longer matches the repository +- a memory is too noisy or too broad +- a stronger memory replaces a weaker one + +### Scope And Isolation + +Default to project-scoped memory. Use global memory only for stable user +preferences or cross-project practices that are clearly safe to share. + +Do not let one project's architecture assumptions silently guide another +project. If a runtime supports namespaces or stores, install Mnemon with an +explicit store strategy. + +## Installation + +Installation is an agent task. Give this document to the target agent and ask it +to install Mnemon into its own runtime using the closest available mechanism. + +The preferred user flow is: + +```text +1. Give the target agent INSTALL.md. +2. INSTALL.md tells the agent where SKILL.md and GUIDELINE.md are. +3. The agent installs those files into its own native instruction system. +4. The agent adds the four hook phases if its runtime supports hooks. +5. The agent verifies behavior with small recall/writeback/no-op checks. +``` + +This means Mnemon does not need a dedicated adapter before a runtime can use it. +An adapter or `mnemon setup --target ` command may automate the same +steps later, but the architecture should remain understandable and installable +from markdown alone. + +### Prerequisites + +The target machine should have the `mnemon` binary available: + +```bash +mnemon --version +``` + +If missing, install it with one of the project-supported methods: + +```bash +brew install mnemon-dev/tap/mnemon +``` + +or: + +```bash +go install github.com/mnemon-dev/mnemon@latest +``` + +### Install The Skill + +Install a skill, rule, or instruction file that teaches the agent: + +- Mnemon is an external memory tool. +- The core protocol is `remember`, `recall`, `link`, and lifecycle commands. +- The agent should inspect structured command output instead of guessing. +- The agent should follow this harness guideline for memory decisions. + +The skill should stay focused on command syntax and capability. The guideline in +this document owns judgment policy. + +### Install The Guideline + +Install this document, or the Memory Guideline section of it, into the runtime's +persistent instruction mechanism. + +Valid forms include: + +- a skill reference +- a rules file +- a project instruction file +- a plugin guide +- a system prompt section +- a checked-in repository document that the runtime loads at startup + +The guideline should be visible enough that the agent can apply it without the +user repeating memory instructions in every session. + +### Install The Hooks + +If the runtime supports hooks, install four lightweight hooks: + +| Hook | Required Behavior | +|---|---| +| Prime | Tell the agent to load Mnemon skill/guideline and respect the active store | +| Remind | Before task work, ask whether recall is useful | +| Nudge | After task work, ask whether writeback is useful | +| Compact | Before compaction, preserve only critical continuity | + +Hook scripts may print natural-language reminders. They do not need to run +heavy memory operations themselves. + +Hook scripts also do not need to be identical across runtimes. The required +contract is the phase behavior, not the script body. For example: + +- Codex can use hooks plus `AGENTS.md`, skills, or local instructions. +- Claude Code can use `CLAUDE.md`, skills, slash commands, settings hooks, or + project/user memory files. +- OpenClaw can use plugin hooks and skills, but Mnemon should not require an + OpenClaw-specific memory engine. +- Skill-first runtimes can express most behavior directly as skills, memory + guidance, and lightweight reminders. + +If a runtime lacks hooks, use rules or persistent instructions that simulate the +same checks: + +```text +At task start, decide whether Mnemon recall is useful. +At task end, decide whether durable memory writeback is useful. +Before compaction, preserve critical continuity. +``` + +### Verify Installation + +An installation is acceptable when the agent can: + +1. Explain when it should recall and when it should skip recall. +2. Run `mnemon recall` for a relevant task. +3. Write a durable memory with provenance. +4. Avoid writing memory for a trivial task. +5. Preserve critical state before compaction if the runtime exposes that event. + +## Evaluation + +The harness is working when: + +- recall improves task continuity or decision quality +- writeback produces future value +- memory volume stays controlled +- stale memories can be superseded +- project stores do not pollute one another +- the agent can explain why it recalled or remembered something + +The harness is failing when: + +- hooks force memory into every task +- the agent saves ordinary chat as memory +- old memory overrides current repository facts +- memory grows faster than recall quality +- global memory leaks project-specific assumptions + +## Lightweight Self-Evolution + +Self-evolution should start as a lightweight markdown loop, not a heavy +framework. + +The full v0.2 architecture is consolidated in +[Self-Evolution Harness Design](../design/SELF_EVOLUTION_HARNESS.md). + +Mnemon should not automatically rewrite runtime behavior. It should help the +agent notice repeated experience, preserve evidence, and propose markdown +changes that a human or repository review can accept. + +```text +experience + -> Mnemon memory + -> LLM reflection + -> markdown candidate + -> diff / PR / human review + -> installed skill, guideline, rule, contract, or eval +``` + +This is the practical path because LLM agents already understand markdown +instructions well. Skills, rules, install guides, and harness guidelines are +cheap to write, inspect, diff, review, and revert. + +### What Evolves + +The first evolution targets should be text assets: + +| Asset | Evolves When | Example | +|---|---|---| +| **Skill** | A repeated procedure works across tasks | A release workflow, migration workflow, review workflow | +| **Guideline** | A memory policy needs sharper judgment | "Do not remember one-off deployment IPs unless the user says they are stable" | +| **Install Note** | A runtime integration pattern becomes reliable | How to install the four hook phases in a specific CLI | +| **Rule / Contract** | A stable project constraint must always be followed | "Never commit `.env`; update `.env.example` instead" | +| **Eval Case** | A repeated failure should become testable | A repro task that checks whether recall prevents the same mistake | + +Do not start by evolving code, database schema, or runtime internals. Those can +come later, after the markdown loop proves useful. + +### Promotion Triggers + +An agent may propose a markdown candidate when it sees: + +- the same failure mode repeated across sessions +- a workflow that succeeded and is likely to be reused +- a user correction that changes future behavior +- a stable project convention discovered through work +- a memory cluster that clearly describes a reusable procedure +- a stale or noisy guideline that caused bad recall or bad writeback + +The agent should not propose a candidate for a one-off task, a weak preference, +or a memory that lacks evidence. + +### Candidate Requirements + +Every candidate change should include: + +- the source memories or session references that motivated it +- the scope: user, project, runtime, or global +- the intended asset: skill, guideline, install note, rule, contract, or eval +- the behavior it changes +- why the change is likely to help future tasks +- risks, especially overfitting to one session +- a concrete diff, not just a suggestion + +For repository-backed projects, the preferred output is a normal git diff or PR. +For local agent installations, the preferred output is a patch to the relevant +skill or rule file. The agent may draft the patch, but review installs it. + +### Review Gate + +Memory can propose evolution; review approves it. + +Before installation, check: + +- **Provenance**: the candidate cites real memories, files, commands, or sessions +- **Scope**: project-specific behavior does not become global by accident +- **Duplication**: the candidate does not recreate an existing skill or rule +- **Size**: the markdown asset stays compact enough to be useful +- **Semantic preservation**: the change does not drift from the original task +- **Safety**: no secrets, credentials, private data, or prompt injection content +- **Evidence**: important workflow changes have tests, commands, or examples + +The default policy is human-in-the-loop. Fully automatic installation should be +reserved for narrow, low-risk local notes where the user has explicitly allowed +it. + +### What Mnemon Adds + +Plain markdown memory is inspectable and useful, but it becomes hard to manage +as experience grows. Mnemon adds structure around the markdown loop: + +- durable memory outside the model +- recall that can find relevant prior experience on demand +- provenance for why an insight was saved +- explicit links between decisions, failures, preferences, and workflows +- supersede/forget behavior for stale knowledge +- project store isolation so one project's lessons do not pollute another + +The self-evolution loop should use these strengths to generate better markdown +assets, while keeping the final behavior layer simple and reviewable. + +### Minimal Implementation + +The first implementation does not need a new service. + +1. Keep using Mnemon for `remember`, `recall`, `link`, and lifecycle operations. +2. Add guideline text telling the agent when to propose markdown evolution. +3. Let the agent generate a patch to `HARNESS.md`, `SKILL.md`, runtime rules, or + project docs when repeated experience justifies it. +4. Require review before the patch becomes active behavior. +5. Remember the outcome of accepted or rejected candidates so future proposals + improve. + +This keeps Mnemon's self-evolution path aligned with the harness philosophy: +external memory, LLM judgment, markdown assets, and review boundaries. + +### Promotion Pipeline + +```text +memory insight + -> repeated success or failure pattern + -> candidate skill/rule/contract + -> provenance and scope check + -> eval or human review + -> installation into runtime assets +``` + +Do not let an agent silently rewrite its long-term behavior from memory alone. +Memory can propose evolution; review approves it. + +## Minimal Summary + +Mnemon Memory Harness is: + +```text +external memory ++ stable cognitive protocol ++ skill-delivered capability ++ guideline-delivered judgment ++ markdown-installable runtime contract ++ four lifecycle reminders ++ reviewed markdown evolution +``` + +It is intentionally not a runtime adapter framework.

+- agent 正在长时间间隔或上下文压缩后恢复任务。 +- 任务可能重复已知失败模式。 +- 用户要求与先前风格、策略或 policy 保持一致。 + +较弱的 recall 触发条件： + +- 简单的一次性命令。 +- 当前上下文已经清楚的纯局部代码修改。 +- 可完全由当前 prompt 或可见仓库回答的问题。 + +Recall 结果是证据，不是权威。当前用户指令、当前仓库状态和已验证来源优先于陈旧记忆。 + +### Remember + +只记 durable insight。 + +适合写入 memory 的内容： + +- 稳定用户偏好 +- 项目约定 +- 架构或产品决策 +- 重复失败模式和修复方式 +- 非显而易见的 setup 或部署事实 +- 未来 agent 应遵守的约束 +- supersede 旧决策的新决策 + +不适合写入 memory 的内容： + +- secret、credential、token 或私密数据 +- 临时进度流水账 +- 原始对话日志 +- 未验证假设 +- 源码中已经显而易见的事实 +- 未来大概率不会再用到的噪音实现细节 + +每条 durable write 都应包含足够 provenance，让未来 agent 能判断这条记忆是否仍然适用。 + +推荐 provenance： + +- `source`：user、agent、system、repo、docs、command output +- `source_ref`：文件路径、命令、issue、PR、conversation 或 hook phase +- `reason`：为什么值得记住 +- `confidence`：这个 insight 的可靠程度 +- `evidence`：可用时给出具体证据 +- `scope`：project、user、runtime 或 global + +### Link + +当关系对未来 recall 有用时，建立 link。 + +有用的 link： + +- 一个决策 supersede 另一个决策 +- 一个失败由特定 setup 或依赖导致 +- 一个偏好适用于某个项目或 runtime +- 一个

+不要让一个项目的架构假设静默影响另一个项目。如果 runtime 支持 namespace 或 store，安装 Mnemon 时应明确 store strategy。 + +## 安装 + +安装是一个 agent task。把本文交给目标 agent，要求它用最接近自身 runtime 的机制，把 Mnemon 安装进自己的环境。 + +推荐的用户流程是： + +```text +1. 把 INSTALL.md 交给目标 agent。 +2. INSTALL.md 告诉 agent SKILL.md 和 GUIDELINE.md 在哪里。 +3. agent 将这些文件安装到自身原生指令系统。 +4. 如果 runtime 支持 hook，agent 添加四个 hook phase。 +5. agent 用小型 recall/writeback/no-op 检查验证行为。 +``` + +这意味着，一个 runtime 不需要先拥有专用 adapter 才能使用 Mnemon。 +Adapter 或 `mnemon setup --target ` 命令可以在之后自动化同样步骤，但架构本身应保持仅靠 Markdown 就可理解、可安装。 + +### 前置条件 + +目标机器应能访问 `mnemon` binary： + +```bash +mnemon --version +``` + +如果缺失，使用项目支持的安装方式之一： + +```bash +brew install mnemon-dev/tap/mnemon +``` + +或： + +```bash +go install github.com/mnemon-dev/mnemon@latest +``` + +### 安装 Skill + +安装一个 skill、rule 或 instruction 文件，教会 agent： + +- Mnemon 是外部记忆工具。 +- 核心协议是 `remember`、`recall`、`link` 和生命周期命令。 +- agent 应读取结构化命令输出，而不是猜测结果。 +- agent 应遵守本文 harness guideline 做记忆决策。 + +Skill 应专注于命令语法和能力说明。本文中的 guideline 负责判断策略。 + +### 安装 Guideline + +将本文，或其中的“记忆 Guideline”部分，安装到 runtime 的持久指令机制中。 + +有效形式包括： + +- skill 引用 +- rules 文件 +- project instruction 文件 +- plugin guide +- system prompt section +- runtime 启动时会读取的仓库文档 + +Guideline 应足够可见，使 agent 不需要用户每个 session 重复记忆规则也能应用它。 + +### 安装 Hooks + +如果 runtime 支持 hook，安装四个轻量 hook： + +| Hook | 必须行为 | +|---|---| +| Prime | 告诉 agent 加载 Mnemon skill/guideline，并尊重当前 store | +| Remind | 任务开始前询问 recall 是否有用 | +| Nudge | 任务结束后询问 writeback 是否有用 | +| Compact | 压缩前只保存关键连续性 | + +Hook 脚本可以只打印自然语言提醒。它们不需要自己执行重型 memory 操作。 + +不同 runtime 的 hook 脚本也不需要完全相同。真正需要保持的是 phase 行为契约，而不是脚本正文。例如： + +- Codex 可以使用 hooks 加 `AGENTS.md`、skill 或本地指令。 +- Claude Code 可以使用 `CLAUDE.md`、skill、slash command、settings hooks 或 project/user memory 文件。 +- OpenClaw 可以使用 plugin hooks 和 skill，但 Mnemon 不应要求一个 OpenClaw-specific memory engine。 +- Skill-first runtime 可以把绝大多数行为直接表达为 skill、memory guidance 和轻量提醒。 + +如果 runtime 没有 hook，用 rules 或持久指令模拟同样检查： + +```text +任务开始时，判断 Mnemon recall 是否有用。 +任务结束时，判断 durable memory writeback 是否有用。 +上下文压缩前，保存关键连续性。 +``` + +### 验证安装 + +当 agent 能做到以下行为时，安装可接受： + +1. 解释何时应 recall、何时应跳过 recall。 +2. 针对相关任务运行 `mnemon recall`。 +3. 写入带 provenance 的 durable memory。 +4. 面对 trivial task 时避免写入 memory。 +5. 如果 runtime 暴露压缩事件，则能在压缩前保存关键状态。 + +## 评估 + +Harness 工作正常的表现： + +- recall 改善任务连续性或决策质量 +- writeback 产生未来价值 +- memory 体量受到控制 +- stale memory 可以被 supersede +- project store 不互相污染 +- agent 能解释为什么 recall 或 remember + +Harness 失败的表现： + +- hook 强制每个任务都使用 memory +- agent 把普通聊天保存成 memory +- 旧 memory 覆盖当前仓库事实 +- memory 增长速度高于 recall 质量增长 +- global memory 泄漏项目特定假设 + +## 轻量自进化 + +自进化应先从轻量 Markdown loop 开始，而不是先做重型 framework。 + +完整 v0.2 架构已收敛到 [Self-Evolution Harness 设计](../../design/SELF_EVOLUTION_HARNESS.md)。 + +Mnemon 不应自动改写 runtime 行为。它应帮助 agent 发现重复经验、保存证据，并提出 Markdown 变更候选；这些候选必须由人类或仓库 review 接受后才生效。 + +```text +experience + -> Mnemon memory + -> LLM reflection + -> markdown candidate + -> diff / PR / human review + -> installed skill, guideline, rule, contract, or eval +``` + +这条路径现实可行，因为 LLM agent 已经很擅长读取 Markdown 指令。Skill、rule、install guide 和 harness guideline 都容易编写、检查、diff、review 和回滚。 + +### 演化什么 + +第一阶段应优先演化文本资产： + +| Asset | 何时演化 | 示例 | +|---|---|---| +| **Skill** | 某个流程在多个任务中反复有效 | 发布 workflow、迁移 workflow、review workflow | +| **Guideline** | 记忆策略需要更精确的判断 | “除非用户说明稳定，否则不要记一次性部署 IP” | +| **Install Note** | 某个 runtime 集成方式已经可靠 | 如何在某个 CLI 中安装四个 hook

被证明有用后，再考虑更重的工程实现。 + +### Promotion 触发条件 + +Agent 可以在以下情况提出 Markdown 候选： + +- 同一失败模式跨 session 重复出现 +- 某个 workflow 成功且未来很可能复用 +- 用户纠正改变了未来行为 +- 工作中发现稳定项目约定 +- 一组 memory 明确描述了可复用流程 +- 陈旧或噪音 guideline 导致了错误 recall 或错误 writeback + +对于一次性任务、弱偏好或缺少证据的 memory，agent 不应提出候选。 + +### 候选要求 + +每个候选变更都应包含： + +- 触发它的 source memories 或 session references +- scope：user、project、runtime 或 global +- 目标资产：skill、guideline、install note、rule、contract 或 eval +- 它会改变什么行为 +- 为什么它可能帮助未来任务 +- 风险，尤其是对单个 session 的过拟合 +- 具体 diff，而不只是建议 + +对于有仓库的项目，推荐输出普通 git diff 或 PR。对于本地 agent 安装，推荐输出对相关 skill 或 rule 文件的 patch。Agent 可以起草 patch，但 review 才能安装它。 + +### Review Gate + +Memory 可以提出演化；review 决定是否批准。 + +安装前检查： + +- **Provenance**：候选引用真实 memory、文件、命令或 session +- **Scope**：项目特定行为不会误升为 global +- **Duplication**：候选没有重复已有 skill 或 rule +- **Size**：Markdown 资产保持足够紧凑 +- **Semantic preservation**：变更没有偏离原始任务目的 +- **Safety**：不包含 secret、credential、私密数据或 prompt injection 内容 +- **Evidence**：重要 workflow 变更有测试、命令或示例支撑 + +默认策略是 human-in-the-loop。只有在用户明确允许时，才可以对低风险本地 notes 做全自动安装。 + +### Mnemon 补上的能力 + +纯 Markdown memory 可读、好用，但经验增长后会变难治理。Mnemon 给这个 Markdown loop 增加结构： + +- 模型外部的 durable memory +- 按需召回相关历史经验 +- 记录 insight 为什么被保存的 provenance +- 显式连接 decision、failure、preference 和 workflow +- 对 stale knowledge 做 supersede / forget +- project store 隔离，避免一个项目的经验污染另一个项目 + +自进化 loop 应利用这些优势生成更好的 Markdown 资产，同时让最终行为层保持简单、可 review、可回滚。 + +### 最小实现 + +第一版实现不需要新服务。 + +1. 继续用 Mnemon 执行 `remember`、`recall`、`link` 和生命周期操作。 +2. 在 guideline 中告诉 agent 何时提出 Markdown 演化候选。 +3. 当重复经验足够支撑时，让 agent 生成对 `HARNESS.md`、`SKILL.md`、runtime rules 或项目文档的 patch。 +4. patch 通过 review 后才成为生效行为。 +5. 记住候选被接受或拒绝的结果，让未来 proposal 更准确。 + +这使 Mnemon 的自进化路径保持符合 harness 哲学：外部记忆、LLM 判断、Markdown 资产和 review 边界。 + +### Promotion Pipeline + +```text +memory insight + -> repeated success or failure pattern + -> candidate skill/rule/contract + -> provenance and scope check + -> eval or human review + -> installation into runtime assets +``` + +不要让 agent 仅凭 memory 静默改写自己的长期行为。Memory 可以提出演化建议；review 决定是否批准。 + +## 最小总结 + +Mnemon Memory Harness 是： + +```text +external memory ++ stable cognitive protocol ++ skill-delivered capability ++ guideline-delivered judgment ++ markdown-installable runtime contract ++ four lifecycle reminders ++ reviewed markdown evolution +``` + +它刻意不是 runtime adapter
