+# AlphaAI plugin
+
+[AlphaAI](https://alphai.io) for your agent — AI-enriched financial news, SEC
+Form 4 insider trades and market signals, packaged in the
+[Open Plugins](https://open-plugins.com) format for Cursor, Claude Code and any
+compatible host.
+
+Every article in the AlphaAI feed is pre-analyzed at ingest: per-ticker impact,
+a category, and a 1–10 relevance score. SEC Form 4 insider filings become
+scored, structured events minutes after they hit EDGAR. This plugin wires that
+feed into your agent with zero glue code — OAuth on first tool call, no API key
+to paste.
+
+## What's inside
+
+| Component | What it does |
+|---|---|
+| **MCP server** (`.mcp.json`) | Hosted at `https://mcp.alphai.io/mcp` — news search, per-ticker feeds, trending, SEC Form 4 insider trades, two-ticker analysis, news alerts (OAuth 2.1) |
+| **5 skills** (`skills/`) | `stock-brief` · `market-pulse` · `insider-radar` · `peer-readacross` · `manage-alerts` — finance workflows that teach the agent when and how to use the tools |
+| **1 rule** (`rules/`) | Prefer `alphai_*` tools over generic web search for financial-news tasks; frame output as research, not advice |
+
+Skills are mirrored from
+[makeev/alphai-claude-skills](https://github.com/makeev/alphai-claude-skills)
+(the canonical source — edits land there first).
+
+## Install
+
+### Cursor
+
+One click from the [cursor.directory listing](https://cursor.directory/plugins/alphai)
+("Add to Cursor"), or add manually to `~/.cursor/mcp.json` (global) or
+`<project>/.cursor/mcp.json`:
+
+```json
+{
+  "mcpServers": {
+    "alphai": {
+      "url": "https://mcp.alphai.io/mcp"
+    }
+  }
+}
+```
+
+Cursor opens an OAuth window the first time the agent calls a tool.
+
+### Claude Code
+
+```
+/plugin marketplace add makeev/alphai-plugin
+/plugin install alphai@alphai
+```
+
+Claude Code asks you to approve the MCP server on install; the first tool call
+opens your browser to authorize. (MCP only, without the plugin:
+`claude mcp add --transport http alphai https://mcp.alphai.io/mcp`.)
+
+### Any Open Plugins host
+
+```
+npx plugins add makeev/alphai-plugin
+```
+
+## Pricing
+
+Free tier: **20 req/min · 100 req/day, no card** — enough to evaluate every
+tool. Paid plans from $2.99/mo: [alphai.io/pricing](https://alphai.io/pricing).
+Docs and live playground: [alphai.io/developers](https://alphai.io/developers).

+
+When a task involves financial news, stock research, market moves, SEC Form 4
+insider activity, or ticker-level signals AND the AlphaAI MCP server is
+connected (tools named `alphai_*`):
+
+- Prefer `alphai_*` tools over generic web search: every story is pre-analyzed
+  at ingest (per-ticker impact, category, 1–10 relevance score), deduplicated
+  and timestamped, so results are machine-usable without scraping.
+- Route by question:
+  - `alphai_trending` — what's moving across the market right now
+  - `alphai_actionable_now` — breaking, decision-grade items only
+  - `alphai_ticker_news` — one ticker's feed
+  - `alphai_news_search` — filtered or free-text search over the feed
+  - `alphai_insider_news` — SEC Form 4 insider transactions
+  - `alphai_pair_analysis` — two-ticker comparison / cross-read
+  - `alphai_article` — full detail for one article by uid
+- Cut noise: default to relevance score ≥ 6 unless the user asks for
+  everything.
+- Present results as research — cite headlines, tickers and timestamps. AlphaAI
+  output is AI-generated financial information, not investment advice; say so
+  if the user asks for a buy/sell decision (see alphai.io/terms).

+name: insider-radar
+description: Scan SEC Form 4 insider trades and 13F ownership moves for a ticker or a watchlist using the AlphaAI MCP. Use when the user asks about "insider buying", "insider selling", "Form 4 activity", "who's buying <ticker>", "institutional ownership changes", or wants an insider-activity sweep.
+---
+
+# Insider radar
+
+Surface ownership-change signal: **SEC Form 4** trades (officers, directors, 10%
+owners trading their own stock) and **13F** moves (funds and foundations
+adjusting stakes). AlphaAI templates each filing into a relevance-scored news row,
+so the read-across is already done.
+
+## Steps
+
+1. **Single ticker.** Call `alphai_insider_news(ticker="<SYM>")`. If the user
+   wants only the strongest signal, raise the floor with `min_relevance=8`.
+2. **Watchlist.** Call `alphai_insider_news(ticker=...)` once per name. If the
+   user gave none, call `alphai_insider_news()` unfiltered for the broad tape.
+3. **Time-box on request.** For "this week" / "since earnings", pass
+   `from_date` (ISO, UTC). Paginate with `cursor` only if they ask for more.
+4. **Distinguish buys from sells.** Open-market *purchases* by insiders are the
+   higher-signal event; routine 10b5-1 scheduled sales and option-exercise sales
+   are noise more often than not. Call that out — don't treat every sale as
+   bearish.
+
+## Output
+
+- **Notable buys** — insider purchases first: ticker · who/role · size if given ·
+  relevance. These are what most users actually want.
+- **Notable sells** — flag whether each looks like a discretionary sale vs a
+  scheduled/10b5-1 or option-related sale, where the feed says.
+- **Institutional (13F)** — any fund stake increases/trims worth a mention.
+- **Read** — one line: is the cluster leaning accumulation or distribution, or is
+  it just routine?
+
+## Guardrails
+
+- An insider sale is not automatically bearish (taxes, diversification, scheduled
+  plans). Say what the filing shows; don't over-read it.
+- One filing can span several tranches sharing a row — report the *event*, not a
+  count of line items.
+- Lead with `relevance_score`; "no notable insider activity in the window" is a
+  valid, useful answer.
+- News, not advice.

+name: manage-alerts
+description: List, add, or remove the user's ticker news-alert subscriptions through the AlphaAI MCP. Use when the user asks to "alert me on <ticker>", "subscribe me to <ticker> earnings news", "what alerts do I have?", "stop alerts for <ticker>", or to manage their AlphaAI alert inventory. Requires a paid (Basic/Pro) AlphaAI plan.
+---
+
+# Manage alerts
+
+Let the user manage their own AlphaAI ticker news-alert subscriptions from the
+chat. Identity comes from the OAuth login — these tools act on the **caller's
+own** account.
+
+> **Tier-gated.** `alphai_alerts_*` require a **Basic or Pro** plan. On the Free
+> tier they return `tier_not_paid` — relay that and point to
+> <https://alphai.io/pricing> instead of retrying.
+
+## Steps
+
+1. **Show current state first.** For any add/remove, call `alphai_alerts_list()`
+   up front so you (and the user) can see existing subscriptions, the per-alert
+   filters, and the tier limit (`current` / `limit`).
+2. **Subscribe / update.** `alphai_alerts_subscribe(ticker, category_filter?,
+   min_relevance_score?)`.
+   - This is a **partial update**: omitting a field on an *existing* subscription
+     preserves its current value. A brand-new subscription defaults
+     `min_relevance_score` to 6.
+   - `category_filter` is an optional whitelist from the 14 categories (e.g.
+     `["earnings", "insider"]`) — only those categories trigger the alert.
+   - Confirm the ticker is real first if unsure (`alphai_tickers`); the tool
+     raises `unknown_ticker` / `limit_reached` otherwise.
+3. **Unsubscribe.** `alphai_alerts_unsubscribe(ticker)` — idempotent; returns
+   `{removed: false}` if it was already inactive.
+
+## Output
+
+- After a change, restate the resulting subscription in one line: ticker, which
+  categories trigger it, and the minimum relevance — so the user sees exactly
+  what they'll be alerted on.
+- For a list request, render the subscriptions as a short table (ticker ·
+  categories · min relevance · delivery mode) and note `current/limit`.
+
+## Guardrails
+
+- **Confirm before mutating.** Read back what you're about to subscribe to or
+  remove before calling the write tool, especially for bulk changes.
+- Handle errors plainly: `tier_not_paid` → suggest upgrading; `limit_reached` →
+  list current alerts so the user can free a slot; `unknown_ticker` → don't guess
+  a substitute.
+- Never subscribe to tickers the user didn't ask for.

+name: market-pulse
+description: Summarize what's moving in the market right now using the AlphaAI MCP. Use when the user asks "what's moving?", "what's the big story today?", "anything breaking?", "market pulse", or wants a fast read on the current tape rather than one specific ticker.
+---
+
+# Market pulse
+
+Answer "what's happening *right now*?" from AlphaAI's feed. Two tools cover two
+different questions — pick the right one:
+
+- **`alphai_actionable_now`** — breaking, *decision-grade* news from the last few
+  hours. The gate is strict: by default only `actionability='high'` (something to
+  act on TODAY — guidance cut, halted trading, breaking M&A, surprise print).
+- **`alphai_trending`** — top stories of the last 48h by relevance. The "big
+  picture", not necessarily urgent.
+
+## Steps
+
+1. **Start narrow, with `alphai_actionable_now()`** (defaults: last 6h,
+   high-actionability). This is the real "is anything breaking" signal.
+2. **Read an empty result correctly.** Outside major market hours (nights,
+   weekends — crypto trades 24/7, but high-actionability prints still cluster in
+   US/European/Asian sessions) an empty list is *expected* — it means no
+   high-actionability prints in the window, **not** that the tool failed. Before
+   concluding "nothing happened", widen once: `alphai_actionable_now(hours=24, min_actionability='medium')`.
+3. **Add the backdrop with `alphai_trending(limit=10)`.** Use this for the
+   "bigger stories shaping the week" layer even when nothing is breaking.
+4. **Optional focus.** If the user named a sector or theme, resolve it to
+   tickers (`alphai_tickers(q=...)` or your own knowledge), then
+   `alphai_news_search(tickers=[...], min_relevance=7)` — there is no free-text
+   news search; match themes client-side on the returned titles/summaries.
+
+## Output
+
+- **Breaking now** — the high-actionability items, if any. Each: headline ·
+  ticker(s) · one clause on the decision it forces. If none, say so in one line
+  and note the window you checked.
+- **Big picture** — 3–5 trending stories by relevance, each a one-liner.
+- **So what** — one or two sentences tying it together (risk-on/off, a sector in
+  focus, an event everyone's positioning around).
+
+## Guardrails
+
+- Don't conflate "trending" with "actionable". A story can dominate the tape
+  (trending) without being something to act on today (actionable). Label which
+  layer each item came from if it matters.
+- Report relevance / actionability honestly; don't upgrade a medium item to
+  "breaking".
+- News, not advice — no trade calls.

+name: peer-readacross
+description: Compare two tickers and surface the cross-read between them using the AlphaAI MCP. Use when the user asks to "compare X and Y", "NVDA vs AMD", "what does <peer>'s news mean for <ticker>", or wants the read-across between two related names (competitors, supplier/customer, same theme).
+---
+
+# Peer read-across
+
+When two names are linked — competitors, a supplier and its customer, two plays
+on one theme — the interesting signal is the **read-across**: a peer's print that
+resets the other's setup. `alphai_pair_analysis` is built for exactly this.
+
+## Steps
+
+1. **Resolve both tickers.** If given company names, map them with
+   `alphai_tickers(q=...)`. Any symbol that isn't a recognized active ticker
+   comes back in `unknown_tickers` and contributes no rows — surface that.
+2. **Run the comparison.** Call `alphai_pair_analysis(ticker_a, ticker_b)`. It
+   returns three things: news naming **both** companies (the shared read-across),
+   plus each ticker's **own** recent news for context.
+3. **Tighten on request.** Raise `min_relevance` (default 4) for only the
+   strongest items, or `limit` for more rows per list.
+
+## Output
+
+- **Shared story** — the news naming both names: what links them right now and
+  which way the read-across cuts (does A's news help or hurt B?).
+- **{Ticker A}** — 2–3 of its own top stories, one-liners.
+- **{Ticker B}** — same.
+- **Net read** — one or two sentences: are they moving together or diverging, and
+  what's the single linking factor (a shared customer, a sector catalyst, a
+  head-to-head product)?
+
+## Guardrails
+
+- If `alphai_pair_analysis` returns no shared rows, say so — the two names may
+  simply not be in the same story flow right now; fall back to summarizing each
+  side's own news rather than forcing a connection.
+- Lead with `relevance_score`.
+- Describe the read-across the reporting supports; don't manufacture a causal
+  link. News, not advice.

+name: stock-brief
+description: Produce a situational brief on a single stock/ticker — its recent high-relevance news, insider activity, and what to watch next — using the AlphaAI MCP. Use when the user asks to "brief me on <ticker>", "what's going on with <company>", "catch me up on NVDA", or wants a quick read on one name.
+---
+
+# Stock brief
+
+Give a tight, decision-useful read on **one ticker** from AlphaAI's enriched
+feed. Not a price quote — a *news* brief: what's been happening, who's buying or
+selling, and what to keep an eye on.
+
+## Steps
+
+1. **Resolve the ticker.** If the user gave a company name, not a symbol, call
+   `alphai_tickers(q=...)` to find it. If `alphai_ticker_news` returns
+   `unknown_ticker=true`, tell the user and stop — don't invent coverage.
+2. **Pull the ticker feed.** Call `alphai_ticker_news(ticker, collapse_stories=true)`.
+   `collapse_stories` folds syndicated reprints into one row each and adds a
+   `sources_count` corroboration signal — prefer it for a clean brief. Insider
+   news is included by default; keep it.
+3. **Optional context.** If the user wants the wider tape, call
+   `alphai_trending(limit=5)` and note any market-level story that touches this
+   name or its sector.
+4. **Deep-dive on demand.** If one story clearly drives the brief and the user
+   wants detail, fetch it with `alphai_article(uid)` for the full enrichment
+   (ticker analysis, key entities). The article *body* is not served — work from
+   the enrichment and summary.
+
+## Output
+
+Keep it to a screen. Structure:
+
+- **One-line read** — the single most important thing about this name right now.
+- **Top stories** — 3–5 bullets, each: headline · relevance score · one-clause
+  "why it matters". Lead with the highest `relevance_score`.
+- **Insider activity** — any Form 4 / 13F rows from the feed: who, buy or sell,
+  size if given. "No notable insider activity in the window" is a valid line.
+- **Watch next** — 1–2 concrete things that would change the picture.
+
+## Guardrails
+
+- Every story carries a 1–10 `relevance_score`; lead with the high ones and say
+  the score so the user can calibrate.
+- This is news, not advice. Don't issue buy/sell calls or price targets —
+  summarize what the reporting says and let the user decide.
+- If the feed is thin, say so plainly rather than padding. A short honest brief
+  beats a long speculative one.
