Human-authored; `/init` regenerates it. +2. **Skills as reusable directories of capability** under `/.kimi-code/skills/` (`packages/agent-core/src/skill/scanner.ts:8-11`), rendered into `{{ KIMI_SKILLS }}` (`system.md:147`). +3. **JSONL session records** for resume / replay — wire log of a specific session, not consulted by future sessions. + +**The gap**: nothing carries semantic facts from one session to the next except (a) the user-edited `AGENTS.md` (process-coarse, human-maintained) and (b) per-session JSONL (not cross-session). There is no agent-writable, semantic, cross-session store; no per-fact addressability; no scope merging tuned for memory; no `/memory` curation surface. Community issue [#1167](https://github.com/MoonshotAI/kimi-code/issues/1167) (closed) requested hierarchical memory and remains unimplemented — the historical kimi-code position has been "use AGENTS.md," which collapses the static-instructions axis and the dynamic-memory axis into a single human-maintained file. + +**Why now / why this shape**: + +- **Anthropic Memory Tool (`memory_20250818`, public beta 2025-08)** establishes the client-side files-with-primitives pattern: `view / create / str_replace / delete` against a sandboxed directory. Our tool surface aligns directly: file-backed, agent-driven, with `view / list / read / write / update / delete` operations. +- **Claude Code's `MEMORY.md` index-pointer pattern** keeps a small index permanently in context and lazily reads per-fact bodies on demand — bounds context cost (≤8 KB) while preserving recall. +- **File > vector DB at CLI agent scale.** Typical per-project memory volume is under ~50 facts; vector indexing adds binary deps and opacity with no measurable recall benefit. Plain Markdown stays grep-able, diff-able, version-controllable, zero-binary-dep. +- **Static AGENTS.md and dynamic memory are complementary, not redundant.** AGENTS.md is human-authored project policy; memory is agent-authored runtime fact. Keeping the two surfaces separate respects each one's authoring contract. + +## Discovery Results + +Every fact below is direct, citation-anchored evidence the design depends on: + +- AGENTS.md scanner walks user-home → project-root → cwd, with `.kimi-code/AGENTS.md` checked before generic `AGENTS.md` — `packages/agent-core/src/profile/context.ts:54-72`. +- `AGENTS_MD_MAX_BYTES = 32 * 1024`, budgeted leaf-to-root in `renderAgentFiles` — `packages/agent-core/src/profile/context.ts:8,134-165`. +- `loadAgentsMd(kaos, workDir)` is the public entrypoint, re-called by `/init` after generation — `packages/agent-core/src/profile/context.ts:38`, consumed at `packages/agent-core/src/session/index.ts:267`. +- `SystemPromptContext` is the structured handoff to template rendering; `agentsMd` and `skills` are optional string fields — `packages/agent-core/src/profile/types.ts:36-45`. +- Skill scanner constants `USER_BRAND_DIRS = PROJECT_BRAND_DIRS = ['.kimi-code/skills']`; generic `.agents/skills` follows — `packages/agent-core/src/skill/scanner.ts:8-11`. +- `findProjectRoot` walks up looking for `.git` — duplicated between `packages/agent-core/src/profile/context.ts:77-87` and `packages/agent-core/src/skill/scanner.ts:338-347` (extract to shared helper as part of this work). +- system.md template variables include `KIMI_AGENTS_MD`, `KIMI_SKILLS`, `KIMI_ADDITIONAL_DIRS_INFO` — `system.md:5,72,82,86,91,101,121,147`. New `KIMI_MEMORY` slot fits between `KIMI_AGENTS_MD` (line 121) and `KIMI_SKILLS` (line 147). +- Jinja-style `{% if %}` guard pattern already in use for empty sections — `system.md:95` (for `KIMI_ADDITIONAL_DIRS_INFO`). +- Slash command registry shape: `name`, `aliases`, `description`, optional `priority`, optional `availability` — `apps/kimi-code/src/tui/commands/types.ts:5-11`; full registry at `apps/kimi-code/src/tui/commands/registry.ts:3-161`. +- `/init` dispatches in the TUI switch at `apps/kimi-code/src/tui/kimi-tui.ts:1583`; `handleInitCommand` at lines 5601-5627 calls `session.init()` and manages spinner / message queue. +- `generateAgentsMd()` orchestrates `subagentHost.spawn('coder', ...)` → completion → re-load → `appendSystemReminder` with `{ kind: 'injection', variant: 'init' }` — `packages/agent-core/src/session/index.ts:252-280`. This is the canonical orchestration pattern to clone for `/remember`. +- Builtin tool template — `TodoListTool` at `packages/agent-core/src/tools/builtin/state/todo-list.ts:89-133`, with sibling description `todo-list.md` resolved via the `.md` loader. +- File-mutation tool patterns — `EditTool` at `packages/agent-core/src/tools/builtin/file/edit.ts:67-78,118-122` (path validation, write semantics). +- Builtin tools wired at `packages/agent-core/src/agent/tool/index.ts:357-394`; each implements `BuiltinTool` with `name`, `description`, `parameters`, `resolveExecution`. +- Builtin re-exports — `packages/agent-core/src/tools/builtin/index.ts:17`. +- Hook event types include `SessionStart`, `SessionEnd`, `PreCompact`, `PostCompact`, `Stop`, etc. — `packages/agent-core/src/agent/hooks/types.ts:3-17`. `PostCompact` fires fire-and-forget from `packages/agent-core/src/agent/compaction/full.ts:500-504`. +- Frontmatter parser already factored — `parseFrontmatter(text)` at `packages/agent-core/src/skill/parser.ts:81-104` returns `{ data, body }`. Reusable for memory. +- Plan-mode permission policy blocks writes by inspecting `agent.planMode.isActive` — `packages/agent-core/src/agent/permission/policies/plan.ts:80-118`. Memory write guard follows the same `PermissionPolicy` shape. +- Path safety helpers — `canonicalizePath`, `isWithinDirectory`, `PathSecurityError` — `packages/agent-core/src/tools/policies/path-access.ts`. +- Secret-pattern model — `packages/agent-core/src/tools/policies/sensitive.ts`. +- Subagents re-run `prepareSystemPromptContext(kaos, cwd)` per spawn — `packages/agent-core/src/session/subagent-host.ts:286`; cwd inherits from parent. Memory injection thus reaches subagents automatically. +- Full-screen browser template — `TasksBrowserApp` at `apps/kimi-code/src/tui/kimi-tui.ts:4552-4620` (mount via alt-screen takeover). +- Repo commit constraint — no co-author attribution, no agent identity in commit messages or PR descriptions — root `AGENTS.md:11-12`. +- TypeScript style constraints (root `AGENTS.md:33-45`): pass `undefined` directly for optional properties (no conditional spread); `?:` optional properties should not also allow `| undefined`; single-parameter internal methods stay single-param; `export * from './module'` in non-package `index.ts`; `import ... from '#/...'`; do not add many new test files. + +## Glossary + +Canonical labels for this design.

Update is distinct from write so the agent explicitly acknowledges overwrite. +- **FR-5**: The merged index (project overlay over user) is injected into the system prompt at session start and refreshed on every `prepareSystemPromptContext` call (including post-compact), via a new `{{ KIMI_MEMORY }}` placeholder rendered from `SystemPromptContext.memoryIndex`. +- **FR-6**: The user can browse all facts — across both scopes, grouped by scope and type — via `/memory` (full-screen TUI panel, no LLM round-trip). +- **FR-7**: The user can delete a fact via `/memory` with an explicit confirmation step. +- **FR-8**: The user can request a write via `/remember `, which routes through the agent (subagent spawn modeled on `Session.generateAgentsMd`) so that slug, description, and type are LLM-derived from the free-text input. Direct user writes never bypass the agent. +- **FR-9**: On slug collision between scopes in the merged injected index, project overrides user. The user-scope fact remains on disk and addressable for `read` / `delete` when the scope is explicit; `/memory` shows both with a "shadowed" indicator. +- **FR-10**: Subagents see the same merged memory injection automatically, because subagent bootstrap re-runs `prepareSystemPromptContext` and that pipeline includes the memory loader. + +### Non-Functional Requirements + +- **NFR-1**: Index byte cap is 8 KB (after merge + frontmatter strip); per-fact body byte cap is 4 KB. Writes exceeding 4 KB fail with a structured error suggesting a tighter summary. +- **NFR-2**: Index is lazy-loaded; per-fact bodies are never auto-loaded into the system prompt — only fetched on `operation: 'read'`. +- **NFR-3**: Writes are atomic: write body to a tmp file inside the same scope dir, then rename. A crash mid-write leaves either the previous fact intact or the new one — never half-written. The index is recomputed from disk on next render, so it cannot diverge from bodies. +- **NFR-4**: Slug whitelist is `^[a-z0-9](?:[a-z0-9-]{0,62}[a-z0-9])?$` — lowercase letters, digits, hyphens; 1–64 chars; no leading/trailing hyphen. Reject before any filesystem access. +- **NFR-5**: Path-traversal-safe: no `..` segments; resolved path must stay inside the scope dir (reuse `isWithinDirectory` from `tools/policies/path-access.ts`); symlinks inside the memory dir are refused on read. +- **NFR-6**: `operation: 'write' | 'update' | 'delete'` are blocked under `/plan` mode. Enforcement mirrors `PlanModeGuardPermissionPolicy` (`agent/permission/policies/plan.ts:80`). Read operations (`view`, `list`, `read`) pass through. +- **NFR-7**: Memory survives `/compact` and session restart. The system prompt is rebuilt from disk on session start; on `/compact`, the next system prompt re-injects the index automatically (it lives in the system prompt, not in the compacted history). +- **NFR-8**: No new binary dependencies. Pure TypeScript, `node:fs` via the existing `Kaos` abstraction, and the existing `parseFrontmatter` helper. +- **NFR-9**: Tests added to existing files where the unit fits (per root `AGENTS.md`: "do not add too many new test files"). New test files reserved for the memory module surface: `test/memory/*.test.ts` and `test/tools/memory.test.ts`. + +### Out of Scope (explicit non-goals) + +- Vector / semantic search (deferred until per-project memory count materially crosses ~100 facts). +- Automatic write on `SessionEnd` (deferred to v2 — the hook surface stays available, no default behavior in v1: predictability over magic). +- Encryption at rest (rely on OS file permissions; documented for future hardening). +- Cross-machine sync (the user's git or their own sync tool covers project scope; user scope is per-machine by design). +- LLM-driven session summarization into memory (deferred — the agent decides what is worth remembering, mediated by an explicit Memory tool call). +- Multi-user / team-shared memory (single-user model; sharing happens by checking project scope into git). +- Persisting `MEMORY.md` to disk in v1 (rendered-only; may add `kimi memory dump` CLI later). + +## Rationale + +- **File-based over vector DB**: bounded scale (< 100 facts), zero binary deps, grep-able, diff-able, version-controllable. A vector DB at this scale adds binary-dep bloat plus operational opacity with no measurable recall benefit. +- **Index injection over full-content injection**: bounded context cost (8 KB vs potentially 200 KB), but preserves recall — the agent always sees what *exists* and can fetch any body on demand. Same trade-off `AGENTS.md` accepts via byte-budgeting; same model Claude Code's `MEMORY.md` uses. +- **Render-only index (not persisted to disk)**: eliminates the dual-write hazard between body files and an index file. Per-fact `.md` files are the single source of truth. The Memory tool's `view` operation returns the rendered block, so the agent can inspect the index without the index ever needing to land on disk. +- **Agent-driven writes over hook-triggered writes**: every memory write is observable in the wire log, attributable to a specific tool call, and debuggable. Hook-triggered auto-writes are easy to ship and hard to reason about; the hook surface remains free for v2. +- **Scope merge mirrors AGENTS.md and Skills (project overrides user)**: minimum surprise for users already familiar with the existing scope model. +- **Tool surface modeled on Anthropic's `memory_20250818` primitives**: portable across providers, validated by an existing public design, and easily mapped onto the `BuiltinTool` shape (one tool, dispatch on the `operation` discriminant — same pattern as `TodoListTool`). +- **`/memory` is curation-only**: writes always go through the agent, ensuring frontmatter (especially `type` and `description`) is LLM-derived and consistent. The TUI surface stays small (list + view + delete + confirm) and free of LLM coupling, keeping the dialog snappy and easy to test. +- **`/remember ` synthesizes a prompt instead of writing directly**: keeps writes single-sourced through the agent path (one writer, one place to audit), at the cost of one extra LLM turn vs a direct write. Worth it for consistency. + +## Success Criteria + +- A user runs `kimi` on a project, writes a fact (via natural conversation or `/remember`), exits, runs `kimi` again on the same project, and observes that the agent recalls the fact without the user re-explaining anything. +- All BDD scenarios in `bdd-specs.md` pass. +- No regressions in AGENTS.md merging or Skill discovery (existing tests in `packages/agent-core/test/profile/*`, `packages/agent-core/test/skill/*` remain green). +- Performance: index load < 5 ms warm cache for ≤ 50 facts; single write < 20 ms including atomic rename, measured on a developer Mac with local SSD. + +## Detailed Design + +See companion documents: + +- [`architecture.md`](./architecture.md) — System overview, components, data structures, integration points, atomic write strategy, slash-command wiring. +- [`bdd-specs.md`](./bdd-specs.md) — Full Gherkin scenarios (happy path, edge cases, error conditions). +- [`best-practices.md`](./best-practices.md) — Security, performance, code quality, testing strategy, common pitfalls. + +## Design Documents + +- `_index.md` (this file) — Context, Discovery Results, Glossary, Requirements, Rationale, Success Criteria. +- `architecture.md` — Component map, data structures, path resolution, builtin tool spec, slash-command wiring, index format, per-fact format, atomic writes, system-prompt integration, edge cases, open risks. +- `bdd-specs.md` — Gherkin features covering storage layering, agent reads/writes/updates/deletes, `/memory` slash command, system-prompt injection, `/compact` and session-restart resilience, security and path safety, plan-mode interaction. +- `best-practices.md` — Security (path traversal, slug regex, secret detection, plan mode, symlinks), Performance (lazy load, body cap, index budget, concurrency, atomicity), Code Quality (TS style, file conventions, commit rules), Testing strategy, Common pitfalls, Rollout. + +## Open Architectural Risks (carried forward to plan phase) + +1. **gitignore policy for `.kimi-code/memory/`** — should we recommend / auto-add gitignore for project memory? Decision needed before launch. Default in design: **document recommendation; do not auto-write `.gitignore`**. +2. **Index budget overflow handling** — silent drop with telemetry counter `memory_index_truncated` (current design), or LRU rotation? v1 = silent drop + sentinel comment + counter. +3. **`type` × `scope` cross-product** — a `type: project` fact in `user` scope is technically possible. v1 = accept cross-product; document canonical pairings in the tool description. +4. **Subagent write visibility timing** — a subagent's write is visible to its parent only on the next `prepareSystemPromptContext` call (next turn).

Edge Cases + +| Case | Behavior | +|---|---| +| Empty memory dir / dir absent | `loadMemory` returns `""`; template `{% if %}` elides the section.

Tool's `read`/`update`/`delete` on that slug surface `NOT_FOUND` with a hint pointing at the file. | +| `name` ≠ filename | Reject on write (`INVALID_SLUG`); skip with warning on load. | +| Slug collision across scopes | Project wins in the rendered index. Both files remain on disk. `list` exposes both when scope is explicit; `view` shows only the project entry. `/memory` browser shows both with a "shadowed" tag. | +| Index larger than 8 KB | Truncate by dropping User entries first (reverse-alpha), then Project entries (reverse-alpha) until under 8 KB. Append sentinel comment. `list` returns the untruncated listing. | +| Body > 4 KB on write | Reject with `BODY_TOO_LARGE`. | +| Concurrent writes (main + subagent, same slug) | In-process lock serializes; last write wins. | +| Concurrent writes (different slugs) | Proceed in parallel; tmp-rename per-file atomicity. | +| Delete last fact in a scope | Scope's section vanishes from the next rendered index. Directory remains (no automatic cleanup). | +| Reserved filename (`MEMORY.md`) | Loader skips it explicitly; tool refuses writes targeting that slug. | +| User home unavailable (headless CI) | `kaos.gethome()` already trusted by `context.ts:55`; same fallback semantics. If it throws, warn and proceed with project-only memory. | +| Project root differs between turns (cwd change) | `loadMemory` runs per `prepareSystemPromptContext` call. Cwd changes within a single turn are not re-detected — same limitation as `loadAgentsMd`. | +| Symlink inside memory dir | Refused on read with a clear error (no `realpath` follow). | +| Slug containing path separators or `..` | `isValidSlug` rejects.

Uses canonical vocabulary from the `_index.md` Glossary. + +## Security + +**Path traversal prevention.** Reuse `canonicalizePath` + `isWithinDirectory` + `PathSecurityError` from `packages/agent-core/src/tools/policies/path-access.ts`. Do not roll your own. Treat each scope's memory directory as a workspace root for the Memory tool. Any operation resolves the candidate path lexically and then verifies it stays inside the scope's root. Mirror `WriteTool`'s pattern: throw `PathSecurityError`, return `{ isError: true, output: }` from `execute`. + +**Slug whitelist regex.** `^[a-z0-9](?:[a-z0-9-]{0,62}[a-z0-9])?$`. Lowercase only, digits and hyphens, 1–64 chars, no leading/trailing hyphen. Reject anything else **before** touching the filesystem. This single check eliminates `..`, slashes, backslashes, dots, spaces, control characters, and Windows reserved names. + +**Reserved filename.** Loader skips `MEMORY.md` explicitly so a user who manually creates one does not see it ingested as a fact. The Memory tool refuses writes targeting the slug `memory` to keep the reserved name available for a future on-disk index dump. + +**Secret detection (warn, do not block).** Keep the pattern list small and high-precision to minimize false positives. Recommended starter patterns (mirror the spirit of `tools/policies/sensitive.ts`): + +- `sk-[A-Za-z0-9-]{20,}` — Anthropic / OpenAI-style keys +- `gh[pousr]_[A-Za-z0-9]{36}` — GitHub tokens +- `AKIA[0-9A-Z]{16}` — AWS access key id +- `-----BEGIN [A-Z ]*PRIVATE KEY-----` — private keys (pem) +- `xox[baprs]-[A-Za-z0-9-]{10,}` — Slack + +On match, the write **succeeds** but the tool result `output` includes a warning naming the pattern category. The wire log records the category only — never the raw matched value. Do not enforce in v1; document the user's responsibility. + +**Plan-mode write block.** Extend `PlanModeGuardPermissionPolicy` (`packages/agent-core/src/agent/permission/policies/plan.ts:80-118`) to also block the Memory tool when `operation ∈ {write, update, delete}`. Read operations (`view`, `list`, `read`) pass through. The existing pattern (matching `Write` / `Edit`, returning `{ kind: 'result', result: { block: true, reason } }`) is the right shape. + +**Symlink handling.** Path policies in this repo are explicitly lexical (no `realpath`) — see the comment in `tools/policies/path-access.ts`. For memory specifically: when opening any file inside a scope directory, `stat` it and refuse if it is a symlink. Kaos does not currently expose `realpath`, so do not pretend to follow safely — refusing is the safe default. Document this; do not invent infrastructure. + +**Frontmatter validation.** Required keys: `name`, `description`, `type ∈ {user, feedback, project, reference}`. Validate with the zod schema in `MemoryRecordSchema`. Reject early; never persist invalid frontmatter even partially. + +## Performance + +**Lazy index loading.** Mirror `loadAgentsMd`'s shape: read both scope directories only when `prepareSystemPromptContext` runs. Do not pre-warm at session construction. The `kaos.gethome()` + `findProjectRoot` + `stat` sequence is cheap; replicate it. + +**Bodies are never preloaded.** Only `view` / `list` touch the per-scope directories at session start (for index assembly); only `read` / `update` / `delete` open a body, one at a time, on explicit Memory tool invocation. This is the whole point of the index design — protect it. + +**Index byte budget (8 KB) and truncation order.** When the merged rendered index exceeds 8 KB: + +1. Compute byte length per entry (slug + type + description, no body). +2. Drop User entries first, in reverse-alpha order, until under budget. +3. If still over budget, drop Project entries in reverse-alpha order. +4. Append the sentinel: ``. + +Do not split mid-entry. Mirror `renderAgentFiles` in `profile/context.ts` for the budgeting loop structure, but keep it simpler — AGENTS.md has 32 KB; memory has 8 KB. + +**Concurrency.** v1: single-writer assumption per process. The agent is the only writer in a session; the slash command UI emits a prompt that triggers the tool, so writes serialize through the agent loop. **Do not add lockfiles in v1.** Document the assumption. If two `kimi-code` instances target the same repo, last-writer-wins on bodies; the index always recomputes correctly because it reads bodies fresh. + +In-process: per-store async lock keyed by `${scope}:${slug}` serializes same-slug writes. Different-slug writes proceed in parallel. + +**Atomic write pattern.** For each write / update: + +1. Write body to `.tmp--.md` in the same scope dir. +2. `kaos.rename(tmpPath, finalPath)` — POSIX-atomic on the same filesystem. + +For delete: plain `kaos.rm(path)`. Missing file → return `false` (idempotent). + +The index is **not persisted** in v1, so there is no dual-write hazard. The index is recomputed from disk on every `prepareSystemPromptContext` call. + +Surface I/O failures with the same error shape `WriteTool` uses (`ENOENT` → actionable message; other errors → `error.message`). + +## Code Quality (kimi-code-specific) + +**Match `todo-list.ts` structurally.** New file `packages/agent-core/src/tools/builtin/state/memory.ts` next to `todo-list.ts`. Same exports pattern: `MemoryInputSchema`, `class MemoryTool implements BuiltinTool`. Description sourced from sibling `memory.md` (the markdown loader resolves automatically). Re-export from `tools/builtin/index.ts:17` alongside `state/todo-list`. + +**Match `loadAgentsMd` for the loader.** New module `packages/agent-core/src/memory/loader.ts` exporting `loadMemory(kaos, workDir): Promise`. Reuse `findProjectRoot` (currently private and duplicated in `profile/context.ts` and `skill/scanner.ts` — extract to a shared helper in `packages/agent-core/src/memory/find-project-root.ts` and update both callers). + +**Wiring in `agent/tool/index.ts`** (around line 372 next to `new b.TodoListTool(...)`): + +```ts +new b.MemoryTool(kaos, workspace), +``` + +The tool needs `kaos` for I/O and `workspace.workspaceDir` to derive the project memory directory. It does **not** need `ToolStore` — memory is on-disk, not session state. + +**System-prompt template variable.** Add `KIMI_MEMORY` to `buildTemplateVars` in `packages/agent-core/src/profile/resolve.ts` (next to `KIMI_AGENTS_MD`). Add a corresponding section in `packages/agent-core/src/profile/default/system.md` immediately after the AGENTS.md / Project Information block. Render nothing (empty string) when the merged index is empty; the surrounding template uses the same `{% if %}` guard pattern as `KIMI_ADDITIONAL_DIRS_INFO` (`system.md:95`) so an empty memory produces no section header at all. + +**TypeScript style (root `AGENTS.md:33-45`):** + +- Optional properties use `name?: string`, never `name?: string | undefined`. +- Pass-through with `{ scope }` — never `{ ...(scope ? { scope } : {}) }`. +- Internal single-param methods stay single-param. Do not promote `slug: string` to `{ slug: string }`. +- Imports use `#/...`, not relative `../../../`. +- `export * from './module'` in non-package `index.ts` files. + +**Test file hygiene.** Per root `AGENTS.md` ("do not add too many new test files"): add memory tool tests to `test/tools/memory.test.ts` only because no sibling test file covers the same surface. Memory loader tests **extend** `test/profile/context.test.ts` (which already covers `loadAgentsMd`). Plan-mode block tests **extend** the existing plan-policy test file, not a new one. Browser tests live in `apps/kimi-code/test/tui/memory-browser.test.ts` because no `kimi-tui` test file exists for that shape. + +**Commit conventions:** no co-author attribution, no agent identity in commit messages or PR descriptions (root `AGENTS.md:11-12`). PR title must follow conventional commits. A changeset entry is required before PR; never write `major` without explicit user confirmation. + +**Slash-command wiring:** + +1. Register `memory` and `remember` in `BUILTIN_SLASH_COMMANDS` (`apps/kimi-code/src/tui/commands/registry.ts`) alongside `init` and `compact`. +2. Wire `case 'memory':` and `case 'remember':` into the dispatch switch in `kimi-tui.ts` around line 1586. `memory` mounts the browser via alt-screen takeover (mirror `showTasksBrowser` at `kimi-tui.ts:4552-4620`). `remember` queues a synthesized prompt and dispatches a subagent (mirror `handleInitCommand` at `kimi-tui.ts:5601-5627`). + +## Testing Strategy + +Translate each Gherkin scenario in `bdd-specs.md` into a vitest `it()` whose description is the scenario name (e.g. `it('writes a fact and creates the body file atomically', ...)`). + +**Fixtures.** Reuse the `mkdtemp` + `vi.spyOn(localKaos, 'gethome')` mock pattern from `packages/agent-core/test/profile/context.test.ts`. Create both a fake home and a fake project root per test; clean up in `afterEach`. + +**Atomic-write tests.** For "index recomputes correctly after a partial write", inject a Kaos stub that throws on the `rename` step. Assert the final body path does not exist afterward (only the tmp file does — which the test then cleans). Do not rely on real `kill -9`. + +**Cross-scope merge tests.** Stand up both fixture directories, populate slugs, assert the merged output order (Project first, User second) and that collisions surface project-wins in the rendered index while the user-scope file remains on disk. + +**Path-safety tests.** Pass `../foo`, `foo/bar`, absolute paths, control chars, uppercase, leading/trailing hyphens, the reserved `memory` slug. Assert all rejected before any I/O. Do not assert filesystem state — assert the tool returns `isError: true` with the right reason. + +**Plan-mode interaction.** Extend the existing plan-policy tests to cover Memory tool blocking. Do not create a new test file just for this. + +**TUI browser tests.** Test list rendering, scope filtering, delete-confirm flow, and the `/remember` → subagent dispatch sequence. Use the existing `TasksBrowserApp` test scaffolding (if present) as a template; otherwise build minimal scaffolding shared with future browser tests. + +## Common Pitfalls + +- **Do not conflate memory with `AGENTS.md`.** AGENTS.md is user-authored static project instructions. Memory is agent-managed dynamic facts. They sit next to each other in the system prompt but have independent lifecycles, loaders, and templates. Keep `loadAgentsMd` and `loadMemory` as parallel functions, not one merged loader. +- **Do not auto-write on `SessionEnd` in v1.** Writes must be explicit Memory tool calls. Predictability beats magic; auto-summarization can be added later behind a flag. +- **Do not preload bodies.** If you find yourself reading every `.md` body at session start, you have defeated the entire index design. +- **Do not pluralize the tool name.** It is `memory` (singular), to match `todo-list`, `write`, `read`. Not `memories`. +- **Do not store secrets.** Detect, warn, log — but do not block in v1. Document that the user is responsible. +- **Do not allow silent overwrite.** `write` to an existing slug fails with `EXISTS`; the agent must explicitly call `update`. Silent overwrite is a footgun and indistinguishable from a stale-cache bug. +- **Project memory may be committed to git.** Document this clearly in the Memory tool's `memory.md` description. Suggest `.gitignore` opt-out for personal/sensitive content. Do **not** auto-write `.gitignore` entries. +- **Do not invent vocabulary.** Use canonical labels from the `_index.md` Glossary exactly. Specifically: not "store", not "kb", not "knowledge base", not "entry" (other than the TS type `MemoryEntry`), not "namespace" instead of "scope". +- **Do not couple to `ToolStore`.** Unlike `TodoListTool`, memory lives on disk, not in agent-level session state. Bodies survive process exit by design. +- **Subagent context inherits automatically.** Subagents call `prepareSystemPromptContext` independently (`session/subagent-host.ts:286`). This automatically gives them the index. Do not pass memory state through `spawn` arguments. +- **Render-only `MEMORY.md` in v1.** Do not write a `MEMORY.md` to disk in v1. The index is rendered each prompt build. If you find yourself implementing a persisted `MEMORY.md`, stop — that introduces the dual-write hazard the design explicitly avoids. +- **Subagent write visibility lags one turn.** A subagent's `write` is visible to its parent only on the parent's next turn. Document this in the Memory tool description so the agent does not expect intra-turn coherence. + +## Migration / Rollout + +- New feature, no migration required. +- Opt-in by use: users get memory the moment the agent calls the Memory tool. +- No config flag in v1 (no opt-out beyond not asking the agent to write). +- Document the `.kimi-code/memory/` convention in the Memory tool's `memory.md` description, including the `.gitignore` suggestion for users who want project memory to stay personal. +- Update root `AGENTS.md`? **No** — reserved for hot-path rules. Document memory in a short doc under `docs/` and reference it from `memory.md` so the agent itself knows the conventions. +- Changeset entry: **`minor` bump** (new feature, no breaking changes). Do not write `major` without explicit user agreement (per root `AGENTS.md` hard rule). +- Telemetry events to emit: `memory_write`, `memory_update`, `memory_delete`, `memory_truncated`.

From 04871ff617104edfc80b370d770a702c62815538 Mon Sep 17 00:00:00 2001 From: Frad LEE Date: Thu, 28 May 2026 12:39:36 +0800 Subject: [PATCH 3/3] feat: native cross-session memory with /memory and /remember MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a file-backed Markdown memory subsystem to kimi-code. Per-fact .md bodies live under `~/.kimi-code/memory/` (user scope) and `/.kimi-code/memory/` (project scope). A rendered MEMORY.md-style index is injected into the system prompt under a new `# Memory` section (capped at 8 KB); per-fact body content is capped at 4 KB. New surfaces: - **Memory builtin tool** (`packages/agent-core/src/tools/builtin/state/memory.ts`) with operation discriminator `view | list | read | write | update | delete`. Atomic tmp-rename writes; slug regex `^[a-z0-9](?:[a-z0-9-]{0,62}[a-z0-9])?$`; symlink refusal; secret-pattern warn-only scan. - **`/memory` slash command** — full-screen TUI browser for curation (list grouped by scope, body preview, explicit-confirm delete, scope filter). Shadowed user-scope entries annotated when overridden by project scope. - **`/remember ` slash command** — routes the text through the agent (subagent spawn mirrors `Session.generateAgentsMd`) so frontmatter fields (slug / description / type / scope) are LLM-derived. - **System-prompt injection** via new `KIMI_MEMORY` template var, sitting between `# Project Information` and `# Skills`. Re-rendered each turn, surviving `/compact` and visible to subagents on next spawn. - **Plan-mode policy** extension blocks write/update/delete; read ops pass. - **Telemetry events** `memory_write / memory_update / memory_delete` (no body in payload) and `memory_index_truncated` (drop count). - **Session API + RPC + SDK**: `listMemory`, `deleteMemory`, `remember`. Storage shape: - Per-fact body files only on disk. `MEMORY.md` filename is reserved (skipped by the loader) and the index is rendered on demand — eliminates the dual-write hazard between index and bodies. - Project entries override User entries on slug collision in the rendered index; the user-scope file remains on disk and addressable. Tests: 4532 passing across 354 files (full repo). New tests cover the 45 BDD scenarios in the design folder plus telemetry / resilience / plan-mode / security cases. Existing AGENTS.md and Skill loading verified unchanged. Plan execution artifacts live under `docs/plans/2026-05-27-native-memory-plan/` (sprint contracts, handoff summaries, per-batch evaluations) for audit. The design folder `docs/plans/2026-05-27-native-memory-design/` was committed earlier. Out of scope (deferred): vector / semantic search; auto-write on SessionEnd; encryption at rest; cross-machine sync; LLM-driven session summarization. --- .changeset/add-native-cross-session-memory.md

The design's invariant — "memory lives in the system prompt; loader reads disk on every call; subagents call `prepareSystemPromptContext` independently" — is preserved. +- **Architectural observation (not a defect this batch)**: `Agent.useProfile` snapshots `systemPrompt` as a frozen string into `config.systemPrompt`. The Memory section is therefore captured at profile-load time. In the current flow this is only re-rendered on session bootstrap (`bootstrapAgentProfile`) and subagent spawn. If a future batch needs a written fact to appear mid-session in the same parent agent without re-bootstrapping the profile, this is the site to revisit. Tests for this batch operate at the `prepareSystemPromptContext` layer (matching the task spec), not at the in-process Agent layer, so no defect surfaces here. +- **Telemetry surface (Task 19 resolution)**: `Agent.telemetry: TelemetryClient` from `agent-core/src/telemetry.ts`. Pattern: pass through constructors, wrap each `.track(...)` call in try/catch for fire-and-forget. `loadMemory` now takes an optional 3rd `telemetry` param; `MemoryTool` takes an optional 3rd `telemetry` param. Both default to no-op behaviour to keep existing call sites and unit-tests compatible. +- **No body content leaks in telemetry**: enforced via tests that JSON-stringify each payload and assert the exclusive body token does not appear; the `emit()` helper only ever receives `{ scope, slug }` objects by construction. diff --git a/docs/plans/2026-05-27-native-memory-plan/evaluation-round-1-batch-5.md b/docs/plans/2026-05-27-native-memory-plan/evaluation-round-1-batch-5.md new file mode 100644 index 0000000000..98d5837313 --- /dev/null +++ b/docs/plans/2026-05-27-native-memory-plan/evaluation-round-1-batch-5.md @@ -0,0 +1,99 @@ +# Self-Evaluation — Batch 5 + +**Batch**: 5 (Session API + RPC + SDK + MemoryBrowserApp + slash dispatch) +**Date**: 2026-05-28 +**Checklist**: `docs/retros/checklists/code-v1.md` v1 + +## Files Produced + +### Source files +- `packages/agent-core/src/session/index.ts` (modified) — `listMemory`, `deleteMemory`, `remember` methods + `memoryStore` builder + `rememberPrompt` / `rememberCompletionReminder` helpers. +- `packages/agent-core/src/session/rpc.ts` (modified) — `listMemory`, `deleteMemory`, `remember` RPC handlers;

If we want live refresh during a streaming `/remember`, that would be a later iteration — not in this batch's scope. +- **RPC payload shape decision**: `listMemory` returns the full body in the RPC payload. Per design, body is capped at 4 KB per fact; index budget is 8 KB, so total wire size is bounded. Including the body avoids a second per-fact RPC call when the TUI displays the read-only preview. Filter/`shadowed` flag is computed server-side at `SessionAPIImpl.listMemory` from project-scope membership. +- **Subagent prompt template**: exact text from the sprint contract / design `architecture.md` §5 is used verbatim in `rememberPrompt`. The test asserts the prompt contains the user text and the write-operation directive but does not pin the full template by string equality, so minor wording polish in Batch 6 won't break tests. diff --git a/docs/plans/2026-05-27-native-memory-plan/evaluation-round-1-batch-6.md b/docs/plans/2026-05-27-native-memory-plan/evaluation-round-1-batch-6.md new file mode 100644 index 0000000000..3c8cd7d44a --- /dev/null +++ b/docs/plans/2026-05-27-native-memory-plan/evaluation-round-1-batch-6.md @@ -0,0 +1,81 @@ +# Evaluation Round 1 — Batch 6 + +**Batch**: 6 (final wrap-up) +**Date**: 2026-05-28 +**Checklist**: `docs/retros/checklists/code-v1.md` +**Verdict**: PASS + +## Artifacts under evaluation + +- `packages/agent-core/src/tools/builtin/state/memory.md` (rewritten from placeholder) +- `docs/reference/memory.md` (new) +- `.changeset/add-native-cross-session-memory.md` (new) + +## Checklist results + +### CODE-VER-01 — All verification commands exit 0 + +Each command run independently in a fresh shell with `eval "$(fnm env)"` + `fnm use 24.15.0` (project's `.nvmrc` pins 24.15.0; the default shell Node was 24.14.1 and rejected by `engines.node`). + +| Command | Exit | Output tail | +|---|---|---| +| `pnpm typecheck` | 0 | `packages/migration-legacy typecheck: Done` / `packages/node-sdk typecheck: Done` / `@moonshot-ai/kimi-code typecheck` clean | +| `pnpm test` | 0 | `Test Files 354 passed \| 4 skipped (358)`, `Tests 4532 passed \| 25 skipped \| 2 todo (4559)`, duration 20.02s | +| `pnpm lint` | 0 | `Found 240 warnings and 0 errors.` (pre-existing warnings, none new) | +| `pnpm build` | 0 | `apps/kimi-code build: Build complete in 1448ms`, `dist/main.mjs 4.78 MB` | +| `ls .changeset/` | 0 | new `add-native-cross-session-memory.md` present alongside existing entries | + +**Result: PASS** — all four verification commands exit 0. + +### CODE-QUAL-01 — No TODO/FIXME/HACK/XXX/STUB markers in produced files + +```bash +grep -rn -E '(TODO|FIXME|HACK|XXX|STUB)' \ + packages/agent-core/src/tools/builtin/state/memory.md \ + docs/reference/memory.md \ + .changeset/add-native-cross-session-memory.md +# exit 1 (no match) + +grep -rni -E '\bstub\b' +# exit 1 (no match) +``` + +**Result: PASS** — zero matches across produced files. + +### CODE-QUAL-02 — No stub implementations + +Not applicable — this batch produced only Markdown content (tool description, reference doc, changeset).
