+</Update>
+
+<Update label="2026-09-08" description="Shared agent plugin runtime">
+
+**Changed:**
+- Consolidated the coding-agent integrations into `integrations/agent-plugin-core/`: one Python runtime, one TypeScript utility library, and six canonical Python-plugin skill templates. Native adapters retain each host's event contracts and capabilities.
+- Python plugins ship generated, self-contained `core/` and `skills/` directories. Builds validate portable schemas and skills, parse native JSON, and reject generated-file drift, missing files, stale generated files, and symlinks. TypeScript packages bundle the shared source into their distributable JavaScript and verify their entry points.
+- Replaced the old `integrations/mem0-plugin/` layout with native host directories and one portable `integrations/mem0-agent-plugin/` package. Updated marketplace paths, installation guides, and integration-skill links. OpenCode now lives in `integrations/opencode-plugin/`.
+- Native Python plugins expose one local, read-only `search_memories` MCP tool and six skills: search, remember, forget, status, pause, and resume. The shared search tool accepts optional `run_id` with every scope (`repo`, `dir`, and `mine`) to recall memories from a specific coding-agent session. Omitting it searches across sessions. This local tool is separate from the hosted Mem0 MCP server's tool set.
+
+**Fixes:**
+- Hooks, controls, MCP servers, and detached workers use the same host-specific data directory. Detached workers retain the host identity and telemetry source; `--plugin-data-dir` reaches the shared resolver.
+- Session-end workers flush the conversation already captured by hooks. Repeated and concurrent response hooks no longer duplicate an answer, while identical answers after separate prompts are preserved.
+- Shared prompts and responses are redacted without the previous 6,000-character cutoff. Python extraction splits oversized messages without dropping text to enforce each request's input budget. Flush event selection and claims share one write transaction, delayed handoffs are replaced atomically, and permanent HTTP polling errors fail promptly.
+- Extraction instructions refer to the current coding agent. Python redaction covers JSON-shaped credentials; both telemetry runtimes recursively remove sensitive keys, including keys inside nested lists.
+- New Git repository writes use a hash of the remote identity in `agent_id`. Search and explicit shared-memory deletion include both current and legacy repository IDs within the repository's `app_id`. Existing memories are not rewritten. Legacy IDs retain their original ambiguity for matching owner/repository names on different Git hosts.
+
+**Packaging:**
+- Claude Code, Cursor, Codex, Kimi, Antigravity, and the portable Python bundle are versioned at `0.3.1`. OpenCode, Pi Agent, and DeepSeek Harness are `0.3.0`; OpenClaw is `1.1.0`. Each host's changes and upgrade considerations are listed in its tab.
+- Python and TypeScript CI run their respective runtime suites. Package checks build the installable artifacts, check generated-file consistency, and reject TypeScript output that still imports monorepo source.

+
+**Fixes:**
+- Adapter errors are logged and exit successfully so a memory failure does not terminate the host hook. Sidekick telemetry reports zero parent-injected context because this host uses self-search.

 | Hook | Event | What it does |

+What you type is stored as yours. Captured agent summaries are stored as the assistant's, so its suggestions never become your stated preferences.
+
+## Antigravity 1.1.25 workarounds
+
+Antigravity 1.1.25 can validate a plugin's `mcp_config.json` without loading the server. Check whether Mem0 is registered:
+
+```bash
+agy mcp list
+```
+
+If `mem0` is absent, register the plugin's bundled server with Antigravity's supported global MCP command, then start a new session:
+
+```bash
+agy mcp add mem0 python3 ~/.gemini/config/plugins/mem0/core/mcp_server.py
+```
+
+The same release can send hooks with an empty `workspacePaths` array. For the `agy` CLI, pass the current repository explicitly:
+
+```bash
+MEM0_CWD="$PWD" agy
+```
+
+The adapter uses `MEM0_CWD` only when Antigravity omits the workspace. If neither value is available, it skips recall and capture instead of writing memories under an incorrect repository scope.
+
+## Search and capture
+
+The local `search_memories` tool accepts `query`, `top_k`, `category`, `scope` (`repo`, `dir`, or `mine`), and optional `run_id` with every scope. Use a known session ID to recall memories saved in that session; omit it to search across sessions. See [search scopes](/integrations/claude-code#search-scope) for the shared Python search contract, including legacy repository memory compatibility.
+
+Captured prompts and responses retain their full redacted text without a per-message character cutoff. Large extraction inputs are split across requests without dropping message text; recall output and tool-result previews have separate limits.

 ## Troubleshooting

 - **No tools appearing**: Restart your Antigravity session after installation
- **"Connection failed"**: Verify your key is set: `echo $MEM0_API_KEY`
- **MCP 401 Unauthorized**: If `${MEM0_API_KEY}` interpolation doesn't work in your `agy` version, replace with your literal key in `mcp_config.json`
+- **No `mem0` entry in `agy mcp list`**: Use the Antigravity 1.1.25 global MCP registration command above
+- **Hooks do not capture in the CLI**: Launch `agy` with `MEM0_CWD="$PWD"`
+- **"Connection failed"**: Verify your key is set without printing it: `test -n "$MEM0_API_KEY" && echo configured`

 The plugin follows a simple cycle: capture during a session, extract memories in the background, recall in the next session.

+1. **Capture.** Hooks save the main agent's activity locally: user messages, Claude's answers, changed files, and short test/build results. Direct Sidekick lifecycle records stay local. Subagent results included in the main transcript can provide supporting evidence for extraction; the main agent's final response establishes the outcome. Capture does not call a model.

 2. **Flush.** After every five completed exchanges, a detached background worker sends that batch to Mem0. Large exchanges flush sooner. Ending or compacting the session flushes anything remaining. If the session sits idle, an auto-flush runs after five minutes (configurable with `MEM0_CODE_IDLE_FLUSH_SECONDS`). The timer resets on each new exchange. The worker survives Claude Code exiting.

-3. **Extract.** Each flush sends a single `add` call with `agent_id` (the project identity), `user_id` (you), `app_id` (the repository), and `run_id` (the session). Mem0 classifies each extracted memory as shared project knowledge or a personal preference.

-Unlike Claude Code, Codex has no plugin-host mechanism for auto-wiring hooks from an installed plugin: it only reads hooks from `~/.codex/hooks.json` (or `<repo>/.codex/hooks.json`). Installing the plugin (Option A) does **not** turn hooks on by itself. To enable them, run the bundled installer once against your local clone:
-
-```bash
-python3 <path-to-your-clone>/integrations/mem0-plugin/scripts/install_codex_hooks.py
-```
-
-This merges Mem0's entries into `~/.codex/hooks.json` and is idempotent (safe to re-run after upgrading). It also requires the `codex_hooks` feature flag in `~/.codex/config.toml`:
-
-```toml
-[features]
-codex_hooks = true
-```
-
-The installer prints a reminder if the flag isn't set. Restart Codex after installing hooks or editing the config. To remove: `python3 .../install_codex_hooks.py --uninstall`.
-
-Once enabled, Mem0 hooks into Codex's lifecycle to automatically manage memory:
+Option A registers the hooks with the plugin. No separate hook installer or global `hooks.json` edit is required.

 | Hook | Event | What it does |
 |------|-------|-------------|
-| **Session start** | `SessionStart` | Loads prior memories and displays status banner |
-| **User prompt** | `UserPromptSubmit` | Searches relevant memories before each message |
-| **Pre-tool (3 handlers)** | `PreToolUse` | Blocks MEMORY.md writes; enforces `user_id`/`app_id` on mem0 tool calls; scans files being read for relevant memory context |
-| **Post-tool** | `PostToolUse` | Tracks stats, scans bash errors for related memories |
-| **Stop** | `Stop` | Stores a session summary at the end of every assistant turn (not just at session end) |
-| **Pre-compact** | `PreCompact` | Stores a summary before the context is compacted |
+| **Session start** | `SessionStart` | Initializes the project session and recovers pending capture |
+| **User prompt** | `UserPromptSubmit` | Records each prompt; searches on the first prompt when it has at least 20 characters |
+| **Post-tool** | `PostToolUse` | Records useful tool outcomes for the completed exchange |
+| **Subagent start** | `SubagentStart` | Reuses the parent turn's retrieved memory context in the child |
+| **Subagent stop** | `SubagentStop` | Records the child transcript path and completed result |
+| **Stop** | `Stop` | Captures completed work and starts a background flush when needed |
+| **Pre-compact** | `PreCompact` | Flushes pending capture before context compaction |
+| **Session end** | `SessionEnd` | Flushes any remaining capture in the background |

+Unlike file-based memory plugins, Mem0 is a managed backend: server-side extraction, semantic dedup, and conflict resolution, with memories reusable by integrations that use compatible user identities and search filters.

 ## How it works

-A Cordis plugin is a module exporting `apply(ctx, config)`. This one declares `inject = ['tools']` so it waits for the harness tool registry, then registers the two tools via `ctx.tools.register(...)`. When the plugin unmounts, the tools are removed automatically (Cordis revertible effects).
+A Cordis plugin is a module exporting `apply(ctx, config)`. This plugin waits for the Harness tool and system-prompt services, then uses their native extension points:
+
+- `system-prompt/assemble` recalls memory before a model request.
+- `session/event` captures only completed turns from the durable event stream.
+- `ctx.tools.register(...)` exposes explicit search and add tools.
+
+Cordis removes the listeners and tools when the plugin unmounts. Memory failures are fail-open, so a Mem0 outage does not stop the agent from completing its normal work.

-title: Eve
-description: "Use Mem0 as a first-class memory provider for Vercel Eve agents."
---
-
-[Eve](https://eve.dev/docs/memory) is Vercel's agent framework. A memory provider sits in the agent loop: Eve recalls context before each turn, captures completed turns, and exposes provider tools. `@mem0/eve` is Mem0's implementation of that contract.
-
-This is not the Mem0 MCP connection. MCP gives the model tools it may or may not call. The memory provider runs automatically. The live MCP install is `eve add connection/mem0`.
-
-## Install
-
-```bash
-npm install @mem0/eve
-```
-
-`eve` is a peer dependency. Get an API key from the [Mem0 dashboard](https://app.mem0.ai/dashboard/api-keys).
-
-Create `agent/memory/mem0.ts`:
-
-```ts
-import { defineMemory } from "eve/memory";
-import { byPrincipal } from "eve/memory/scope";
-import { mem0Provider } from "@mem0/eve";
-
-export default defineMemory({
-  description: "Recall and manage durable context for the current user.",
-  provider: mem0Provider({
-    apiKey: process.env.MEM0_API_KEY!,
-  }),
-  scope: byPrincipal,
-});
-```
-
-`eve add memory/mem0` is not in Eve's catalog yet. After Mem0 is listed in the official registry, that command will create the same slot file.
-
-## How it works
-
-1. **Recall.** Before each turn and after compaction, Mem0 searches memories for the locked Eve scope and returns `{ id, content }` messages. Eve injects those as user-role messages attributed to the slot.
-2. **Capture.** After a successful turn, Mem0 adds the user messages from that turn and, when present, that turn's assistant reply. By default (`infer: true`) Mem0 extracts durable facts. Capture is deduplicated per `operationId` on a best-effort basis (an in-process gate plus a durable `metadata.operation_id` lookup); because that check and the write are not atomic and platform writes are asynchronous, a restart or concurrent worker can occasionally capture a turn twice.
-3. **Tools.** The model can call `search`, `remember`, and `forget`. Eve qualifies them as `mem0__search`, `mem0__remember`, and `mem0__forget` when the slot file is `mem0.ts`. `remember` returns `{ status: "saved" }` on a resolved write or `{ status: "queued" }` when the platform accepts it for asynchronous extraction.
-
-Eve owns namespace, scope, and when recall/capture run. Mem0 owns storage, ranking, and extraction. Search, capture, remember, and forget are partitioned by `memory.scope.key`. Forget deletes by id only after confirming the memory belongs to that key.
-
-## Options
-
-```ts

+title: Kimi Code
+description: "Add persistent project memory to Kimi Code with automatic capture, automatic recall, Mem0 skills, and tools."
+---
+
+Kimi Code forgets project decisions between sessions. The Mem0 plugin captures completed work, recalls relevant context before a response, and gives Kimi explicit memory tools and skills.
+
+<Info>Current plugin version: `0.3.2`.</Info>
+
+The explicit `handoff` skill saves session context as a shared local resource in `~/.mem0/handoffs/`. Ask the agent to use `handoff_resource` to list the current project’s resources or resume a saved path from any Mem0 plugin. Requires Python 3.10+; the shared engine is downloaded and verified on first use, then cached.
+
+Sidekick is available only in the [Claude Code plugin](/integrations/claude-code#sidekick-agent).
+
+## Prerequisites
+
+1. A Mem0 Platform account and API key:
+   - [Sign up at app.mem0.ai](https://app.mem0.ai?utm_source=oss&utm_medium=integration-kimi)
+   - [Get your API key](https://app.mem0.ai/dashboard/api-keys?utm_source=oss&utm_medium=integration-kimi) (starts with `m0-`)
+
+2. [Kimi Code](https://www.kimi.com/code) with plugin support.
+
+3. Python 3.10+ and Git on your machine.
+
+## Quick start
+
+Export the key in the shell where you start Kimi Code:
+
+```bash
+export MEM0_API_KEY='your-mem0-api-key'
+kimi
+```
+
+Inside Kimi Code, install the native plugin bundle and reload the session:
+
+```text
+/plugins install https://github.com/mem0ai/mem0/tree/main/integrations/kimi-plugin
+/reload
+```
+
+Run `/plugins info mem0` to confirm that the plugin, MCP server, skills, and hooks loaded.
+
+## What you get
+
+- **Automatic capture:** Kimi records completed exchanges locally and flushes durable project knowledge to Mem0 in the background.
+- **Automatic recall:** Relevant memories are added before Kimi answers the first prompt in a session, if that prompt has at least 20 characters.
+- **Explicit search:** Kimi can call `search_memories` when it needs a more specific answer.
+- **Six memory skills:** Search, status, remember, forget, pause, and resume use the same memory behavior as the other Mem0 coding-agent plugins.
+- **Project scoping:** Memories stay attached to the repository, with separate personal and shared project lanes.
+
+Credentials are redacted before memory capture. If Mem0 is unavailable, hooks fail open so Kimi can continue its normal work.
+
+## How it works
+
+Kimi's native lifecycle events are translated into the shared Mem0 memory lifecycle:
+
+| Kimi event | What Mem0 does |
+| --- | --- |
+| `SessionStart` | Initializes the project session and recovers pending capture |
+| `UserPromptSubmit` | Records each prompt; searches on the first prompt when it has at least 20 characters |
+| `PostToolUse` / `PostToolUseFailure` | Records useful tool results and failures |
+| `Stop` | Captures the completed exchange |
+| `PreCompact` / `SessionEnd` | Flushes pending capture in the background |
+
+The plugin does not register subagent start or stop hooks or supply parent memories to child agents.
+
+## Verify the plugin
+
+In one session, say:
+
+```text
+Remember exactly: the release codename for this repository is ORCHID-9274.
+```
+
+Start a new Kimi session in the same repository and ask:
+
+```text
+What is the release codename for this repository? Do not infer it from repository files.
+```
+
+Kimi should return `ORCHID-9274` from memory.
+
+## Managing the plugin
+
+```text
+/plugins list
+/plugins info mem0
+/plugins disable mem0
+/plugins enable mem0
+/plugins remove mem0
+```
+
+Run `/reload` or start a new session after enabling, disabling, or reinstalling the plugin.
+
+## Search and capture
+
+The local `search_memories` tool accepts `query`, `top_k`, `category`, `scope` (`repo`, `dir`, or `mine`), and optional `run_id` with every scope. Use a known session ID to recall memories saved in that session; omit it to search across sessions. See [search scopes](/integrations/claude-code#search-scope) for the shared Python search contract, including legacy repository memory compatibility.
+
+Captured prompts and responses retain their full redacted text without a per-message character cutoff. Large extraction inputs are split across requests without dropping message text; recall output and tool-result previews have separate limits.
+
+## Troubleshooting
+
+| Problem | Fix |
+| --- | --- |
+| Missing API key | Start Kimi from a shell where `MEM0_API_KEY` is exported. |
+| Plugin changes do not appear | Run `/plugins reload`, then `/reload` or `/new`. |
+| MCP server is disabled | Run `/plugins mcp enable mem0 mem0`, then `/reload`. |
+| No memory in a later session | Wait a moment for the background flush, then ask Kimi to search memory explicitly. |
+| Remove the plugin | Run `/plugins remove mem0`. |

-## Auto-dream (memory consolidation)
-
-The plugin can automatically consolidate stored memories by merging duplicates, dropping stale/sensitive entries, and rewriting vague ones. This keeps your memory set clean over time. It runs at most once per session, and only when **all** gates pass:
-
- **Time**: at least `minHours` (default 24) since the last consolidation
- **Sessions**: at least `minSessions` (default 5) sessions since then
- **Memories**: at least `minMemories` (default 20) stored for the project
-
-A filesystem lock (`~/.mem0/mem0-dream.lock`) keeps two sessions from consolidating at once. Tune the thresholds with a `dream` block in `~/.mem0/settings.json`, or disable entirely with `MEM0_DREAM=false`:
-
-```json
-{
-  "dream": { "enabled": true, "auto": true, "minHours": 24, "minSessions": 5, "minMemories": 20 }
-}
-```
-
-If auto-dream hasn't run yet, it's almost always because a gate hasn't been met (most often too few memories). Run `/mem0-status` to see the exact gate progress (e.g. `sessions 2/5, memories 3/20`), `/mem0-dream` to consolidate **now** regardless of the gates, or lower the thresholds above.
+Automatic capture sends the selected user prompt with its full redacted text, without a per-message character cutoff. It does not capture every prompt or the full assistant transcript. These automatic writes use user and project scope, with the session ID in `metadata.session_id`; session-scoped tools use top-level `run_id`. A session-scoped search therefore does not include automatic writes that lack `run_id`.

+## Confirmation Dialogs

 Destructive and mutating commands use Pi's built-in `ctx.ui.confirm()` dialog before acting:

 - `/mem0-forget` asks "Delete this memory?" before deleting a single match
- `/mem0-pin` asks "Pin this memory?" before modifying it
- Cancelling either operation is always safe. No changes are made
-
-### Pin
-
-`/mem0-pin` uses Mem0's `update()` API to prepend `[PINNED]` to the memory text. This preserves the original memory ID. There is no add+delete cycle that would lose history or change the UUID.
-
-### Dream Consolidation
-
-The plugin includes automated memory maintenance ("dream") that merges duplicates, resolves contradictions, and prunes stale entries. When enabled, dreams auto-trigger after enough sessions, time, and memories accumulate (configurable via `dream.*` settings). Run `/mem0-dream` to trigger consolidation manually at any time. Pinned memories (via `/mem0-pin`) are protected from pruning.

+The `integrations/agent-plugin-core/` directory is the single source for shared Python and TypeScript memory behavior. Native plugins live in their own sibling directories, while `integrations/mem0-agent-plugin/` is the single portable Agent Plugins v1 package. Sidekick is available only in Claude Code. The portable package provides search and skills but no automatic capture; its remember skill cannot save a new memory on its own. Shared Python search accepts optional `run_id` for session-specific recall in every scope. TypeScript integrations reuse the core's lifecycle, formatting, identity, scoping, and telemetry utilities while keeping their public packages and native host APIs unchanged.

 ## What each one is

- **`eve/`** is the Eve memory provider (`mem0Provider`). Eve calls recall on `turn.started` and `compaction.completed`, capture on `turn.completed` when enabled, and exposes `search` / `remember` / `forget` tools. This is not the Mem0 MCP connection.
 - **`vercel-ai-sdk/`** wraps the Vercel AI SDK through a `createMem0` provider. Integrations for AI-SDK repos go through this wrapper, not raw `MemoryClient`.
- **`claude-code-plugin/`** is the Claude Code plugin (v0.3.0, installs as `mem0@mem0-plugins`): local evidence capture via lifecycle hooks, background memory extraction to the Mem0 Platform, a local `search_memories` MCP tool, six `/mem0:*` skills, and the `mem0:sidekick` agent. Pure-stdlib Python — no dependencies to install. Its `core/` + `adapters/claude/` split marks engine vs. harness glue; future per-harness plugins start by copying `core/` and keeping the contract tests verbatim (see its `docs/CONTRACT.md`).
- **`mem0-plugin/`** connects Cursor, Codex, Kimi, Antigravity, and OpenCode to the MCP server at `mcp.mem0.ai` and installs lifecycle hooks for automatic memory capture. Exposes 9 MCP tools: `add_memory`, `search_memories`, `get_memories`, `get_memory`, `update_memory`, `delete_memory`, `delete_all_memories`, `delete_entities`, `list_entities`. The Claude Code plugin moved to [`claude-code-plugin/`](claude-code-plugin/) in v0.3.0 (installs as `mem0@mem0-plugins`); do not run both at the same time.
+- **`agent-plugin-core/`** owns the shared Python memory runtime, TypeScript lifecycle utilities, skill templates, builds, and conformance runner. Claude Code is the behavioral source of truth. Native manifests and adapters live in sibling plugin directories; do not hand-edit their generated `core/` or `skills/` trees. Build and validation details are in [`agent-plugin-core/README.md`](agent-plugin-core/README.md).
+- **`opencode-plugin/`** is a Bun/TypeScript plugin for OpenCode (`@mem0/opencode-plugin` on npm). It registers Mem0 memory tools as an OpenCode plugin with its own skills and telemetry.
 - **`openclaw/`**, **`pi-agent-plugin/`**, **`deepseek-plugin/`** are editor and agent plugins with the same shape. `deepseek-plugin/` registers Mem0 search/add tools as a native DeepSeek Harness (Cordis) plugin.
 - **`n8n-nodes-mem0/`** is an n8n community node: add, search, get, update, delete.
 - **`zapier-mem0/`** is a Zapier Platform CLI app: add, search, get, delete. It deploys to Zapier, not npm, so it is **not** in the release router. Deploy it with `gh workflow run zapier-mem0-cd.yml --ref main` (needs the `ZAPIER_DEPLOY_KEY` secret).

 ## Adding an integration

-1. Create `integrations/<name>/` and build it there, self-contained.
+1. For a native coding-agent host, add `integrations/<name>-plugin/` with `plugin-build.json`, its manifest, and a thin adapter, then generate its shared runtime. Portable clients use the single `mem0-agent-plugin/` package. Independent TypeScript integrations stay self-contained and import shared lifecycle behavior from `agent-plugin-core/typescript/`.
 2. If it publishes to a registry, set `repository.directory: "integrations/<name>"` in `package.json` so npm provenance links to the right subdirectory.
 3. Add `.github/workflows/<name>-checks.yml` and `<name>-cd.yml`. Use `integrations/<name>` in the `paths:` trigger, `working-directory`, and `cache-dependency-path`. Register the release tag prefix in the `case` block in `release.yml`, keeping the bare `v*` arm last.
   **Workflow filenames are load-bearing:** npm OIDC trusted publishing is pinned to repository plus workflow filename. Renaming one breaks publishing.
 4. Register the CI workflow in `ci-gate.yml`: a path filter under the `changes` job, a call job, and an entry in the gate job's `needs` list.
-5. If it is a Claude Code or editor marketplace plugin, register its path in all five `marketplace.json` files: root, `.claude-plugin/`, `.cursor-plugin/`, `.codex-plugin/`, and `.agents/plugins/`.
+5. If it is a Claude Code or editor marketplace plugin, register the generated native bundle path in the applicable marketplace files. Preserve the existing public plugin name.
 6. Document it under `docs/integrations/` and add the page to `docs/docs.json` and `docs/llms.txt`.
 7. Add rows to the table above and to the CI/CD tables in [`../.github/AGENTS.md`](../.github/AGENTS.md).

+
+## 0.3.2
+
+- Add explicit save, project-scoped list, and resume through shared local resources in `~/.mem0/handoffs/`. Every plugin uses one converter, validator, and resource store; memory extraction is not a transcript source.
+- Installable plugins share one pinned runtime cache through a small launcher. First use downloads the exact GitHub commit and verifies SHA-256 digests; subsequent uses verify and reuse the local cache. No transcript is uploaded to GitHub.
+- Preserve the session title, project, readable compaction context, supported images, and completed tool calls/results. Hidden reasoning and harness configuration are excluded. Unsupported records, opaque compaction, and unfinished responses fail explicitly.
+- Requires Python 3.10+. Pi save additionally requires Node.js 22.19+ for its native SDK; list/resume work on Node.js 20. Other source formats may require an explicit completed transcript, directory, and title.
+- Handoff needs no destination CLI, model call, or Mem0 credentials. Resources are private, uniquely named files; saving preserves full supported context and resume returns it as historical evidence without replaying tools.
+- Live host checks: align the handoff skill’s shell permission with its quoted command; accept Codex harness/usage metadata without importing it as conversation; resolve DeepSeek attachment storage through its native optional-service API.
+- Replace strict before-answer and repeated-search instructions with focused optional retrieval. Existing context can answer the question without another search. Search scoping, retrieval limits, and capture scheduling are unchanged.

+This directory is the single source of shared memory behavior for Mem0 coding-agent plugins. Installable plugins remain ordinary sibling directories under `integrations/`.

+├── kimi-plugin/             # Native Kimi package and adapter
+└── antigravity-plugin/      # Native Antigravity package and adapter
+```
+
+Each native directory owns only its manifest, native hooks or adapter, tests, and `plugin-build.json`. Its `core/` and `skills/` directories are generated from this module. They are committed because clients install a self-contained plugin directory and the Agent Plugins specification forbids package files from resolving outside the plugin root.
+
+Sidekick belongs only to Claude Code. Its agent definition is in `claude-code-plugin/agents/sidekick.md`; its hooks are in `claude-code-plugin/adapters/claude/hook.py`. Other plugins must not register Sidekick. The shared core handles memory and native subagent tracking for Claude Code and Codex.
+
+TypeScript integrations (`openclaw`, `opencode-plugin`, `pi-agent-plugin`, and `deepseek-plugin`) import `typescript/src/` at build time. Their package builders include the shared implementation in their normal output; they do not carry checked-in copies.
+
+## Shared memory behavior
+
+The six Python packages use the `search_memories` and `handoff_resource` MCP tools, six memory skill templates, and the handoff command. Native hooks collect conversations and flush them to Mem0 in the background. The portable package uses the Agent Plugins v1 layout so compatible hosts can load its MCP server and skills. It has no lifecycle hooks or flush worker; its bundled `remember` skill assumes automatic capture and cannot save a memory on its own.
+
+Search guidance follows Memo: use a focused question when earlier work could help, reuse available context, and search again only for a specific remaining gap. The TypeScript hosts import one shared guidance constant; conformance checks keep it aligned with the generated Python MCP description and reject strict before-answer or repeated-search prompts. Automatic recall schedules and retrieval limits are independent of this wording.
+
+Python search accepts `query`, `top_k`, `category`, `scope`, and optional `run_id`:
+
+| Scope | Memories searched |
+| --- | --- |
+| `repo` (default) | Shared repository memories and your personal memories in that repository |
+| `dir` | Shared memories from the current directory and its children, plus your personal repository memories |
+| `mine` | Your personal memories in that repository |
+
+`run_id` filters any scope to memories saved in a known coding-agent session. Omit it for recall across sessions; it does not attribute the search request to the current session. Native Python extraction writes include the session's `run_id`.
+
+New Git repository writes use a hashed remote identity for shared `agent_id`. Search and explicit shared-memory deletion include both that ID and the legacy unhashed ID under the same `app_id`. Legacy memories remain accessible, but their original ambiguity between matching owner/repository names on different Git hosts remains.
+
+Captured prompts and responses preserve their full text after secret redaction. Python extraction splits oversized input across requests without dropping message text. The session-end worker flushes the conversation already collected by hooks without adding the final answer again. Search queries, retrieved context, and tool evidence have separate limits.
+
+TypeScript hosts reuse redaction and lifecycle utilities but retain their own tools, scopes, and capture events. They do not inherit the Python `repo`/`dir`/`mine` contract or its background batching. OpenCode captures selected user prompts; Pi and DeepSeek capture completed conversation turns; OpenClaw selects recent messages and earlier summaries, then filters noise. Removing message-length truncation does not turn these integrations into complete transcript archives.
+
+For installation, follow the host guides: [Claude Code](../../docs/integrations/claude-code.mdx), [Cursor](../../docs/integrations/cursor.mdx), [Codex](../../docs/integrations/codex.mdx), [Kimi](../../docs/integrations/kimi.mdx), and [Antigravity](../../docs/integrations/antigravity.mdx).
+
+## Session handoff
+
+`python/session_handoff.py` is the common launcher. `python/handoff_sources.py` reads native transcripts; `python/handoff_engine.py` validates and stores the shared resource. The transcript conversion is adapted from [mem0ai/memo](https://github.com/mem0ai/memo/blob/aeeb1593284d1d2fca3b4bcf1e32ea10f71df549/docs/session-handoff.md).
+
+All ten plugins save to the same local resource directory, `~/.mem0/handoffs/`. Each resource preserves the source host, session title, project, active user/assistant context, paired tool calls/results, and supported images. Readable compaction context is retained; hidden reasoning and harness configuration are excluded. Unknown model-visible content, missing results, and opaque compaction fail explicitly. Saving never summarizes or truncates the context, runs recorded tools, or launches a destination application.
+
+TypeScript adapters supply native active context through `typescript/src/handoff.ts`; OpenClaw supplies its trusted transcript path. The six Python packages generate one shared `handoff` skill with source-specific instructions. Claude saves before model invocation to avoid capturing the handoff command itself; other Python hosts require an explicit completed transcript or neutral bundle.
+
+To continue in another plugin on the same machine, explicitly ask it to list the current project's handoffs and resume the selected resource. Python plugins expose `handoff_resource` with `action: "list"` or `action: "resume", resource: "/absolute/path.json"`. OpenCode, Pi, and OpenClaw expose `/mem0-handoff list` and `/mem0-handoff resume /absolute/path.json`; DeepSeek exposes the same actions on `mem0_handoff`. Resumed context is historical evidence, not instructions to replay old tools. Project-scoped listing uses the repository root; an explicit resource path also supports continuing in a relocated checkout. This is local storage, not cloud sync.
+
+Handoff requires Python 3.10+ and runs independently of memory hooks and Mem0 credentials. Pi's save action additionally requires Node.js 22.19+ for its native SDK; list and resume remain available on Node.js 20. No destination CLI or model call is required.
+
+The engine source exists only here. Installable packages contain the small launcher and `build/handoff-runtime.json`, which pins a Git commit and SHA-256 digests. On first explicit use, the launcher downloads the two source files from GitHub into `~/.mem0/handoff-runtime/<revision>`. All ten plugins verify and reuse that cache, including offline. A missing or invalid cache requires GitHub access; download or digest failures stop the operation. No transcript is sent to GitHub.
+
+Every TypeScript build uses `build/package_handoff.mjs`; the Python builder uses the same manifest. Builds reject source hashes that differ from the pin, and conformance checks reject stale launchers/manifests. To change the engine, commit its source, pin that immutable commit and its file digests, regenerate Python bundles, and rebuild TypeScript packages. No per-plugin engine edits are needed. Before distributing a new pin, retain its source commit with a `handoff-runtime-<full-commit-sha>` tag. Keep these tags after squash merges and branch deletion so fresh installs can still fetch every distributed runtime. These are retention tags, not package releases.
+
+See the [shared changelog](CHANGELOG.md#032) and each plugin's changelog for invocation details.
+
+## Build and verify
+
+From the repository root:
+
+```bash
+python3.11 -m venv /tmp/mem0-agent-plugins
+/tmp/mem0-agent-plugins/bin/pip install \
+  -r integrations/agent-plugin-core/requirements-dev.txt
+
+for host in claude-code cursor codex kimi antigravity; do
+  /tmp/mem0-agent-plugins/bin/python \
+    integrations/agent-plugin-core/build/build.py "$host" \
+    --kind native --check
+done
+
+/tmp/mem0-agent-plugins/bin/python \
+  integrations/agent-plugin-core/build/build.py mem0-agent-plugin \
+  --kind portable --check
+```
+
+Use `--sync` instead of `--check` after changing `python/` or `skills/`. This only replaces generated `core/` and `skills/` content; it does not change manifests, adapters, tests, or the Claude sidekick.
+
+Run every offline Python and TypeScript check and write one machine-readable report:
+
+```bash
+/tmp/mem0-agent-plugins/bin/python \
+  integrations/agent-plugin-core/conformance/run.py \
+  --install \
+  --report /tmp/mem0-plugin-conformance.json
+```
+
+For every TypeScript integration, this also builds the publishable package, verifies its required entry files, and rejects compiled artifacts that still import monorepo source. This keeps published plugins self-contained without committing their `dist/` directories.
+
+The offline suite does not contact Mem0 Platform. An explicit disposable key enables the inherited live scoping suite:
+
+```bash
+export MEM0_API_KEY="m0-disposable-test-key"
+/tmp/mem0-agent-plugins/bin/python \
+  integrations/agent-plugin-core/conformance/run.py \
+  --group live-platform --live \
+  --report /tmp/mem0-plugin-live-conformance.json
+```
+
+Do not put a real key in source files, command history shared with others, or pull-request configuration.
+
+## Add a plugin
+
+For another native Python host:
+
+1. Add `integrations/<host>-plugin/` with its native manifest and the smallest adapter that translates host events.
+2. Add `plugin-build.json` declaring the plugin-root variable and runtime files.
+3. Add one adapter contract test.
+4. Register the host in `build/build.py` and `conformance/run.py`.
+5. Run `--sync`, `--check`, and the conformance command above.
+
+Keep capture, recall, memory scoping, redaction, skill text, and telemetry in this shared module. Host directories should contain only behavior required by their native SDK.
+
+For a TypeScript host, import the shared lifecycle modules directly and keep only native SDK registration in the integration. Do not advertise capture or compaction behavior unless the host exposes the necessary lifecycle seam. Sidekick is limited to Claude Code.
+
+## Host capture capabilities
+
+| Host | Conversation capture | Tool outcomes | Subagent context and correlation |
+| --- | --- | --- | --- |
+| Claude Code | Incremental active transcript branch | Native success/failure hooks | Parent context; native agent ID |
+| Cursor | Prompt and response hooks; duplicate responses suppressed | Native success/failure hooks | No plugin subagent hooks or agent declaration |
+| Codex | Native prompt and final-response fields | Structured failure indicators when present; otherwise unknown | Parent context; native agent ID |
+| Kimi | Prompt hooks and completed v2 wire output | Native success/failure hooks | No plugin subagent hooks or agent declaration |
+| Antigravity | Incremental completed transcript messages, including later prompts | Native tool errors | No plugin subagent hooks or agent declaration |
+| Portable v1 | Explicit memory skills | No native lifecycle hooks | No native subagent declaration |
+
+Python status uses `subagent_runs` and `last_subagent`. Legacy SQLite names and event handling keep existing records and running workers compatible.
+
+An uncorrelated subagent completion is kept as its own record; the plugin never guesses which overlapping run completed. Codex's documented hook fields already match the shared input contract, so no speculative field aliases or unsupported failure event are registered.
+
+Offline conformance exercises the adapters and MCP servers with native-shaped payloads and builds each distributable package. It does not establish that every installed editor or Harness version loads the plugin correctly; those checks require smoke tests in the actual hosts.

+A detached `python3 telemetry.py` drains the spool in one batched PostHog request,
+started once per session and again from the flush worker that is already detached.

+Pure stdlib, matching the rest of the plugin. Opt out with MEM0_TELEMETRY=false.

+Call `search_memories` with the user's question. Treat `--top-k`, `--category`,
+`--scope`, and `--run-id` as tool arguments instead of including them in the
+query.
+
+Omit `top_k` to use Mem0's configured default. Omit `category` to search every
+category. Search again only if a specific gap remains. Omit
+`scope` to use the configured default, normally `repo`: this repository's
+shared memory, which everyone who works in it contributes to, plus your own
+preferences.
+
+Pass `scope` when the question needs something else: `dir` to narrow the
+shared memory to the directory you are working in (a package inside a
+monorepo), `mine` for your own preferences alone.
+
+Pass `run_id` with any scope to retrieve memories saved in a specific coding-agent
+session. Omit `run_id` to search across sessions. It filters the memories returned;
+it does not identify the session making the search request. Use a known session ID,
+never invent one. Return the tool's result directly.

+API key is configured, the event/flush/retrieval counts (`flushes` is the
