# Plugins Guide

## What a Plugin Is

A plugin extends what {{productName}} can do. Each plugin adds a focused capability — contacts management, Telegram messaging, scheduling, email, research. Plugins are modular: you enable only what you need.

{{productName}}'s own capabilities are plugins too. Marketplace plugins (like Stripe) work the same way — {{productName}} manages all of them through conversation.

The tables below are the install catalogue — every plugin the platform can ship. They are not evidence of what is enabled on the current account. For the live install set, ask {{productName}} to call `capabilities-here`.

## Plugin Groups

### Core (always active)

These are part of {{productName}}'s foundation and cannot be disabled:

| Plugin | What it does |
|--------|-------------|
| `admin` | Platform management — system status, account settings, logs, session control. Also hosts the cross-cutting `plainly` skill: every text-producing agent (admin, public, every specialist) applies a plain-English precision pass to prose returned to humans, as a prime-directive prerogative. Agent-to-machine payloads (image-generate prompts, memory-write arguments, cypher) pass through verbatim. This is a prompt-level skill contract, not a hook: each agent's IDENTITY loads `skill-load skillName=plainly` on its first text-producing turn and applies the pass thereafter. Hosts the `superpowers-sprint` skill: structured sprint workflow built on the `superpowers` and `code-review` upstream plugins, dispatched on "run a sprint" or any `.tasks/NNN-*.md` invocation. |
| `memory` | Graph memory — search, write, reindex, and ingest knowledge |
| `browser` | Headless browser rendering — `browser-render` runs a JavaScript-heavy page in the device's Chromium and returns its rendered DOM. The JS-rendering leg of retrieval: WebFetch (summary) / `url-get` (verbatim, server-rendered) / `browser-render` (JS-rendered). |
| `maxy-guide` | User guide and platform documentation (this plugin) |
| `cloudflare` | Cloudflare Tunnel — remote access via your custom domain |
| `scheduling` | Calendar and scheduling — events, appointments, recurring triggers. Any activity involving time (date, timestamp, day of week, month, duration) routes through `time-resolve` first. Two read-only tools (`current-datetime`, `time-resolve`) are always available to every public agent regardless of enabled plugins. |
| `email` | Agent email account — setup, read, send, reply, search, auto-respond |
| `tasks` | Task lifecycle — create, update, list, relate, complete |
| `workflows` | Persistent named workflows — reusable instruction sets |
| `contacts` | CRM contact management — create, lookup, update, list |
| `prompt-optimiser` | Prompt optimiser — two modes. Chat-app mode turns a rough draft or task description into a single finished, copy-pasteable prompt tuned for Opus 4.7 adaptive thinking (claude.ai, Mac, iOS). In-session mode is applied automatically: a standing `UserPromptSubmit` directive hook (`admin/hooks/prompt-optimiser-directive.sh`) injects context every turn telling the admin agent to restate each non-trivial prompt through this skill and act on the restatement, skipped for one-word confirmations, slash-commands, and direct continuations. Compliance is behavioural — the hook steers the agent, it cannot force the skill call. |
| `url-get` | Faithful page retrieval — fetches a server-rendered page, writes a verbatim markdown copy to an account-scoped reference file (no model in the path, so no copyright refusal), and returns the cleaned page text (capped) plus the file path. No summary and no subprocess: a caller that wants a summary invokes url-get from a delegated subagent. Use instead of WebFetch when a faithful copy is needed (e.g. ingesting your own published writing). |

### {{productName}} Plugins (user-selectable)

These are enabled during onboarding and can be added or removed at any time. Some plugins enhance a specific specialist role — when enabled, that specialist gains additional capabilities.

| Plugin | What it does | Enhances |
|--------|-------------|----------|
| `business-assistant` | Customer enquiries, scheduling, quoting, invoicing, daily briefings | Personal assistant |
| `sales` | Buying signal detection, closing techniques, objection handling | Personal assistant |
| `deep-research` | Structured multi-source research — query decomposition, source evaluation, citations | Research assistant |
| `projects` | Structured project execution — phased sprints, investigations, reviews, retrospectives | Project manager |
| `telegram` | Telegram bot — BotFather setup, messaging, channels | Personal assistant |
| `whatsapp` | WhatsApp messaging, pairing, and conversation browsing | Personal assistant |
| `replicate` | Image generation — three models for photorealistic, design, and fast draft images | Content producer, Research assistant |
| `linkedin-import` | Import a LinkedIn Basic Data Export — Profile and Connections today, more CSVs as references land | Database operator |
| `notion-import` | Import a Notion workspace export (markdown + CSV) — pages, databases, hierarchy, attachments, schema-bounded relations, `@person` mentions account-filtered | Database operator |
| `obsidian-import` | Import an extracted Obsidian vault — pages map to `:KnowledgeDocument`, wikilinks resolve to intra-vault pages or existing entities, tags become `:DefinedTerm`, embedded images become `:DigitalDocument`. Two-phase tool (dry-run → operator disambiguation → commit). | Database operator |
| `x-import` | Import an X (Twitter) Basic Data Export — tweet stream renders as one chronological transcript and ingests as a single `:KnowledgeDocument` (`source='x'`); each DM `sessionId` ingests as one `:ConversationArchive` (`source='x-dm'`, keyed on `conversationIdentity`) via `conversation-archive-ingest.sh`. Mentions, replies, and quote-tweet authors resolve to `:Person` on lowercased `xHandle`; every handle and DM senderId confirms against existing nodes (no auto-create). Per-thread KD granularity and `:Post` / `:DirectMessage` labels are explicitly rejected. | Database operator |
| `substack-import` | Import a Substack "Export your data" archive — per-essay `:KnowledgeDocument {kind:'substack-post'}` via librarian/document-ingest with synthetic stable `attachmentId = "substack-post-${substackPostId}"` (survives Substack edits); one `:KnowledgeDocument {kind:'substack-subscriber-roster'}` per import run with `:MENTIONS {mentionContext:'substack-subscription', tier, totalOpens, totalClicks, lastOpenedAt, lastClickedAt, engagementWindowDays}` to each subscriber `:Person` MERGEd on `(accountId, email)`. Engagement aggregates parsed from `email_activity.csv` (or `subscriber_activity.csv` / `emails.csv`); overwrite-on-reimport. No new label, no new edge type, no new graph writer. Images attach via canonical `:HAS_ENCLOSURE` (or `:MENTIONS` fallback). Bulk-gate at >200 posts or >2000 subscribers. | Database operator |
| `memory/skills/conversation-archive` | Source-agnostic conversation transcript ingest. One skill for WhatsApp `_chat.txt`, Telegram, Signal, LinkedIn DMs, Zoom transcript, meeting minutes, iMessage, Slack, X DMs — `--source <enum>` selects the per-source normaliser. Single Bash entry — `bash platform/plugins/memory/bin/conversation-archive-ingest.sh <archive> --source <enum> --participant-person-ids <csv> --scope <admin\|public>` — runs normalise → operator-confirms owner + every distinct sender (owner derived from env via Cypher, no flag) → sessionize at the fixed 8h gap → emit one JSON line carrying prepared sessions (turn-attributed text + per-session cursor). The dispatched specialist iterates the sessions in-turn, produces a typed-section JSON chunking for each, and calls the `memory-ingest` MCP tool with `conversationIdentity` set (writes `:ConversationArchive`, source=<enum>) once per session — chunks + cursor advance commit atomically inside one Cypher transaction, so a kill mid-archive resumes from the next session on re-issue without re-classifying anything already written. Re-imports are delta-append. Auto-creating participants is forbidden — any sender outside the operator-confirmed closed set LOUD-FAILs with `parser-miss`. Distinct from the live `whatsapp` plugin (Baileys). | Database operator |
| `memory/skills/conversation-archive-enrich` | Phase 2 for any named `:ConversationArchive` — source-agnostic per-row insight derivation. Operator-triggered (never auto-fires on Phase 1 completion). Walks the parent's `:Section` chunks in pages via the read-only MCP tool `mcp__plugin_memory_memory__conversation-archive-list-chunks`; the dispatched specialist reads each chunk in-turn and emits claims under the four-kind contract (`mention`, `task`, `preference`, `observed-relationship`); the skill hands those claims to `mcp__plugin_memory_memory__conversation-archive-derive-insights` for per-kind cypher emission, then runs the per-row operator gate (`wire / skip / reject`). Idempotent on `(elementId(chunk), kind, contentHash)` — re-runs collapse identical claims. Confidence floor is a hedging-avoidance instruction the skill embeds in the specialist's per-chunk prompt, not a numeric post-filter; per Task 433 the LLM step runs in-turn from the dispatched specialist rather than as a server-side OAuth round-trip. | Database operator |

### Claude Official (marketplace)

Third-party plugins from the Claude marketplace:

| Plugin | What it does |
|--------|-------------|
| `stripe` | Live access to payment and business data |

### Claude Anthropic Verticals (marketplace, opt-in)

Optional plugins from Anthropic's vertical marketplaces. The installer registers `claude-for-financial-services` and `knowledge-work-plugins` so the install commands work; none are auto-installed. You pick each deliberately during first-run onboarding (Step 1) or by name at any time.

| Plugin | Marketplace | What it does |
|--------|-------------|-------------|
| `kyc-screener` | `claude-for-financial-services` | Parses onboarding documents, runs a rules engine, flags gaps. Outputs are draft work product for human review — your compliance specialist owns sign-off. Relevant to UK estate agents under MLR 2017. |
| `meeting-prep-agent` | `claude-for-financial-services` | Briefing pack before every client meeting, FSI-flavoured templates. Overlaps with the business-assistant calendar-prep flow — choose one deliberately. |
| `pdf-viewer` | `knowledge-work-plugins` | Live interactive viewer to view, annotate, and sign PDFs — mark up contracts, fill forms, stamp approvals, place signatures, download the annotated copy. Click-through replaces conversation for this surface (v0.2.0, different shape from chat-driven skills). |

Install verbatim:

- `claude plugin install kyc-screener@claude-for-financial-services`
- `claude plugin install meeting-prep-agent@claude-for-financial-services`
- `claude plugin install pdf-viewer@knowledge-work-plugins`

### Premium Plugins

Brand decides which premium plugins ship. The brand's `shipsPremiumBundles` field in `brand.json` is the gate; three shapes are supported:

- **omitted / false** — ship nothing from `premium-plugins/` (the legacy Maxy default).
- **`true`** — ship every bundle under `premium-plugins/*` (Real Agent / `realagent-code`).
- **`["bundle-a", "bundle-b"]`** — ship only the named bundle directories (Maxy Code's `["venture-studio"]`). Names with no matching directory on disk are silently dropped; non-allowlisted bundles are stripped from any account that was previously stamped with them.

There is no per-account purchase record; the brand decides the shipping set.

| Plugin | Type | What it does | Public agent |
|--------|------|-------------|-------------|
| `teaching` | Skills | Interactive tutoring, lesson planning, and study pack generation from your knowledge base | Yes — all 3 skills serve students and parents |
| `real-agent` | Bundle (13 sub-plugins) | UK estate agency skills — sales, listings, vendor management, buyer management, lead generation, coaching, business operations, teaching, Loop CRM (five value pillars: auto-respond, viewing lifecycle, pipeline mining, listings prospecting, maintenance & preferences), PropertyData market analytics (valuation, sold prices, £/sqft baselines, £/sqft growth, demand-rent, area risk, planning precedent, UPRN matching, property-type distribution), gov.uk EPC floor-area lookup, property brochures, social-share image cards, A4 market reports, and single-address preval packs (full UK address → 4-page A4 PDF covering valuation, area, and demand). 3 specialist roles (negotiator, valuer, compliance) | 4 sub-plugins (estate-sales, buyers, estate-coaching, estate-teaching) |
| `writer-craft` | Skills + Agent | Manuscript review and writing craft — story architecture, reader engagement, prose craft, editorial practice, and multi-level review | No — writing craft serves the author |
| `venture-studio` | Skills + Agent | Founding-a-business workflow — office-hours discovery, brand pack, zero-to-prototype validation, and the full investor data room (business plan, prospectus, term sheet, deck blueprint, A4 print pipeline). Pre-seeds a `Project` with one `Task` per artefact so nothing gets forgotten. | No — founder-facing only |

**How it works:** Every boot {{productName}} delivers the brand's premium plugins from staging into `platform/plugins/` and stamps `enabledPlugins` against what is actually on disk. No conversation needed — the brand's full set is active from the first turn after install. Updates and reinstalls re-deliver from staging.

Some premium plugins are **bundles** — multiple sub-plugins shipped under one directory in `premium-plugins/`, each independently activatable. For example, Real Agent ships 10 sub-plugins covering different aspects of estate agency work. They are all enabled by default. Sub-plugins you don't want active can be turned off individually with "disable <name>"; enabling or disabling individual sub-plugins does not affect the others.

If you ask {{productName}} about a tool from a plugin your brand does not ship (for example, a Maxy install asking about a Real Agent Loop CRM tool), {{productName}} responds with a structured `<tool-surface-error>` envelope naming the missing plugin and the remedy, rather than improvising with a generic alternative.

**Public agent embedding:** Premium plugins marked as public-eligible have their full content (skills and reference knowledge) embedded in public agent prompts. This means a public agent for a Real Agent member can handle buyer enquiries, book viewings, deliver coaching content, and onboard new applicants — all powered by the premium plugin's domain knowledge. Plugins marked admin-only (listings, vendors, leads, business) are only available to the account owner's admin agent.

Some premium plugins include specialist helpers that {{productName}} can dispatch for specific tasks (e.g. the writer-craft plugin includes a manuscript reviewer). These are activated automatically when the plugin is enabled.

Some premium plugins include pre-built public agent templates — ready-made configurations for customer-facing agents. When you enable the plugin, {{productName}} shows you what templates are available and offers to create agents from them. You review and approve every file before the agent is created. The template is a starting point — you can edit the identity, personality, plugins, and settings to make it yours. The result is a standard public agent, indistinguishable from one you created from scratch.

Some premium plugins ship pre-built workflows that are created when the plugin is enabled. These workflows are fully yours — you can inspect, edit, run, and manage them through conversation, exactly like workflows you create yourself. The plugin provides the starting point; you own the result.

**If a premium plugin ever stops working** — `documents`, `teaching`, anything else you've paid for — and {{productName}} responds as if it doesn't have those tools, the platform's health check (`/api/health.missingPlugins`) will name the affected plugin. Tell {{productName}} "deliver the {{plugin}} plugin" — it re-runs the same delivery step that fires automatically at session start. If the plugin isn't in the device's staging area, re-run the installer for this brand.

## Choosing Plugins

During first-time setup, {{productName}} presents a plugin selection screen where you choose which plugins to activate. Core plugins are pre-selected and locked. Recommended plugins are pre-selected but optional. You can change your mind later.

## Adding or Removing Plugins

Tell {{productName}}:

- "Enable the Telegram plugin"
- "Add the Stripe plugin"
- "Disable the deep-research plugin"

{{productName}} handles the installation or removal. If the plugin requires any setup (API keys, bot tokens, configuration), {{productName}} will walk you through it.

## Viewing Your Plugins

Ask {{productName}}: "What plugins do I have?" or "List my plugins."

## Operator-Authored Plugins (skill-builder output)

Skills you create at runtime through the admin `skill-builder` skill are saved on disk as their own plugin under `data/accounts/{accountId}/plugins/{pluginName}/`. The admin agent calls `mcp__plugin_admin_admin__store-skill`, which composes `PLUGIN.md` (on first call) and `skills/{skillName}/SKILL.md` plus any reference files. The agent supplies `pluginName`, `skillName`, `description`, `publicEmbed`, `body`, and optional references — the path is computed by the tool, never by the agent.

These operator-authored plugins survive reinstall because the installer's wipe zone excludes `data/`. At admin session start the platform mirrors `data/accounts/{accountId}/plugins/*` into the runtime plugins directory so the same `parsePluginFrontmatter` / `assemblePublicPluginContent` / `loadEmbeddedPlugins` loaders that read shipped and premium plugins also pick up operator-authored ones — no special-case loader path. The admin agent sees every operator skill by default; per-skill `publicEmbed: true|false` controls which skills surface to the public agent.

To edit an operator-authored skill later, ask {{productName}} to update it — the admin agent re-runs `store-skill` for the same `pluginName`/`skillName` and the new content overwrites in place. To remove one, delete the directory under `data/accounts/{accountId}/plugins/{pluginName}/skills/{skillName}/` (or the whole plugin) — the next session start re-mirrors the remaining skills only.

`pluginName` collisions with shipped plugin names are refused by `store-skill` with a structured error. See [.docs/agents.md](../../../../.docs/agents.md) § "Operator-authored skills as plugin files" for the full contract.

## Brand Templating (for plugin and skill authors)

Skill content, plugin manifests, agent templates, and reference files reference the operator-visible brand name only via the literal `{{productName}}` placeholder. The platform substitutes from `brand.json.productName` at read time — Maxy installs render `Maxy`, Real Agent installs render `Real Agent`, all from the same source content.

**Author rule:** never write the literal string `Maxy` (or any brand name) in shipped skill, plugin, or template content. Use `{{productName}}` whenever the operator should see the brand name. The audit grep `grep -rn "\bMaxy\b" platform/plugins/admin/skills/ platform/plugins/*/skills/ platform/templates/agents/` must return zero matches; a literal brand name is a defect, not a stylistic choice.

The runtime substitution happens at every read site that flows content into a system prompt or operator-visible UI: the admin agent's `plugin-read` tool (references + `PLUGIN.md`), the `skill-load` tool (SKILL.md by skill name — one-call resolver+reader, the canonical primitive for SKILL.md), the public agent's recursive plugin assembly, and `IDENTITY` / `SOUL` / `AGENTS` / `KNOWLEDGE` markdown reads. Missing or empty `productName` hard-fails — there is no fallback to a default brand string. See [.docs/agents.md](../../.docs/agents.md) § "Brand templating" for the full contract.

## MCP Plugin Observability (for plugin authors)

Every `console.error` line from a plugin's MCP server can be teed into the per-conversation agent stream log so a single `logs-read` call returns one conversation's full timeline — agent events and plugin diagnostics interleaved in chronological order.

**Opt-in (one line at the top of the MCP server's entry file):**

```typescript
import { initStderrTee } from "../../../../lib/mcp-stderr-tee/dist/index.js";
initStderrTee("your-plugin-name");
```

After this, every `console.error("[your-tool]...")` from any tool in the plugin appears as `[<iso-ts>] [mcp:your-plugin-name] [your-tool]...` in the per-conversation stream log `claude-agent-stream-{sessionId}.log`, alongside the usual agent events. The raw per-server file `mcp-your-plugin-name-stderr-{date}.log` is still produced for deep-dive grep.

**Premium plugins.** Source lives at `premium-plugins/<bundle>/plugins/<name>/mcp/src/` — deeper than platform plugins, so the source-relative import to `platform/lib/mcp-stderr-tee/dist/index.js` uses more `../` segments. The bundler rewrites the compiled output to the canonical `../../../../lib/mcp-stderr-tee/dist/index.js` at staging time and ships `platform/lib/mcp-stderr-tee/{dist,package.json}` into `premium-plugins/<bundle>/lib/mcp-stderr-tee/` so the import resolves at deployed depth. The bundler fails loudly if `platform/lib/mcp-stderr-tee/package.json` is missing (it must pin `type` so install-location parent walks cannot mis-classify the dist file) or if any lib referenced by a rewritten import has no source dist.

**How the tee decides which file to write to:** the platform sets `STREAM_LOG_PATH` as an environment variable on every MCP server spawn, pointing to the conversation-scoped stream log. The MCP server does not know about conversations — it just trusts `STREAM_LOG_PATH`. Multiple concurrent conversations produce multiple concurrent MCP server processes, each teeing to its own file; no cross-conversation leakage.

**Bash commands stream straight into the PTY.** Maxy Code's admin and public chat run on the native Claude Code PTY (Task 287). The per-conversation server-side stream log that the retired web-UI dispatcher tailed is gone; agent-invoked Bash commands (including direct `cloudflared` invocations for Cloudflare setup — Task 288) print their stdout and stderr directly, and the PTY renders the output in chat verbatim.

**Retrieve MCP diagnostic lines for a conversation:**

- All servers: `logs-read { type: "system", sessionId: "..." }` → grep `[mcp:<name>]` on the returned stream log.
- One server raw feed: `logs-read { type: "mcp" }` → tails the most recent `mcp-<name>-stderr-*.log` (per-plugin, not per-conversation).

**Tee-state markers** land in the stream log: `[platform] [mcp-tee-attach] server=<name> streamLogPath=...` when the tee wires up, `[platform] [mcp-tee-skip] server=<name> destination=... reason=...` when a destination fails (missing `LOG_DIR`, unwritable path, `STREAM_LOG_PATH` not set, etc.), `[platform] [mcp-tee-detach] server=<name>` on graceful shutdown. If a server invoked tools but no `[mcp:<name>]` lines appear in the conversation's log, look for the skip marker first.

**Main-subprocess stderr.** The same teeing pattern applies to the main Claude Code subprocess's stderr — every line lands in the per-conversation stream log as `[subproc-stderr] …`, with lifecycle markers `[subproc-stderr-tee-attached] pid=…` and `[subproc-stderr-tee-detached] pid=… bytes=N lines=N`. A `bytes=0 lines=0` detach means the tee was attached but the subprocess emitted nothing on stderr — which is the normal state today, because the Claude Code CLI is a bundled Bun runtime binary that does not honour Node's `NODE_DEBUG` env var. The platform records this explicitly with one line per spawn: `[subproc-debug-unavailable] reason=bundled-bun-binary-ignores-node-debug pid=… cli=claude`. A reader who finds a `[spawn]` without these markers should treat that as a regression of the tee infrastructure, not as silence.

## Failure-path observability contract (earlier platform fixes + earlier platform fixes)

The `initStderrTee` wrapper writes to the per-conversation stream log and per-server raw file via `createWriteStream` — async, buffered. Any diagnostic `console.error(…)` followed by an immediate `process.exit(…)` is lost: the event loop never drains the WriteStream before the process terminates. Same race for any synchronous module-load throw: Node's uncaught-exception handler writes the stack to raw fd 2 and exits before the patched async stream flushes. The platform's `[mcp-init-error] tail="(no stderr file)"` line — operationally useless — is the public symptom of this race.

**Two layers now close the gap, each load-bearing on its own:**

1. **Plugin-side sync-write discipline.** Plugins that call `process.exit` during module load (rare — `graph-mcp` is the in-tree example; it spawns a child at boot to proxy upstream stdio) use `fs.appendFileSync` at every named exit path to guarantee the cause lands in both log destinations before exit. Lines follow the `[mcp:<name>] [<plugin-prefix>] <cause>` format so existing `grep '[mcp:<name>]'` investigator paths work. Each destination is wrapped in its own try/catch — an unwritable log must not mask the primary failure. This is the discipline propagated to any plugin author who knows their failure paths.

2. **Parent-side `mcp-spawn-tee` wrapper.** Every node-based core MCP server is spawned via the `lib/mcp-spawn-tee` wrapper rather than `node <entry>` directly. The wrapper spawns the real entry with `stdio: ['inherit', 'inherit', 'pipe']` and writes child stderr chunks to `${LOG_DIR}/mcp-${name}-stderr-<date>.log` via `appendFileSync` while passing the same chunks through to its own stderr (Claude Code's consumer is unchanged). Synchronous `appendFileSync` survives `process.exit`, so the per-server file captures even (a) module-load throws before `initStderrTee` runs, (b) `MODULE_NOT_FOUND` on the entry script itself, and (c) anything else a plugin author missed. The wrapper writes `[mcp-spawn-tee-attached] server=<name> pid=<n>` on attach and forwards SIGTERM/SIGINT to the child. This is the layer that makes capture independent of plugin discipline. Playwright stays unwrapped because it spawns via `npx`, not `node`.

A third layer closes the same gap from the platform side: when `claude-agent.ts` observes an `init` event with any MCP server reporting `status:"failed"`, it reads the last 512 bytes of `${LOG_DIR}/mcp-<name>-stderr-<date>.log` and emits `[mcp-init-error] server=<name> tail=<quoted>` into the stream log. Absent file → `tail="(no stderr file)"`; empty file → `tail="(empty)"`. With the spawn-tee wrapper now interposing on every core MCP, `tail="(no stderr file)"` post-Task-743 means the wrapper itself is broken — file follow-up.

**Signal inventory after a failed session:** `[init] FAILED MCP servers: <names>` (names), `[mcp-init-error] server=<name> tail=…` (cause for each, from the platform's tail probe), `[mcp-spawn-tee-attached] server=<name> pid=<n>` (proof the wrapper attached), `[mcp-spawn-tee-exit] server=<name> code=<n>|signal=<s>` (proof the wrapper saw the exit), and optionally `[mcp:<name>] [<plugin>] …` from plugin-side sync-writes. Their union gives the investigator three independent sources for the same failure.

**Boot-smoke as publish-time gate.** The memory MCP carries `scripts/boot-smoke.sh` that spawns `dist/index.js` with stub env, sleeps 2s, asserts `kill -0 <pid>`, and reports `[boot-smoke] memory ok|FAILED tail=<n-lines>`. Wired to `prepublish` in `plugins/memory/mcp/package.json`. The pattern is propagatable to other plugin MCPs — it's deliberately not generalised yet because each plugin's stub-env requirements differ (memory needs ACCOUNT_ID + PLATFORM_ROOT + NEO4J_URI + SESSION_ID; others differ).
