What it does
Insider Radar is an agent skill from ccplugins/awesome-claude-code-plugins. 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.
Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. It works with Model Context Protocol. The repository describes itself as: Awesome Claude Code plugins — a curated list of slash commands, subagents, MCP servers, and hooks for Claude Code. The licence is Apache-2.0.
When your agent uses it
- The user asks about insider buying
- Insider selling
- Form 4 activity
- Whos buying <ticker
Example prompts
- “insider buying”
- “insider selling”
- “Form 4 activity”
- “/insider-radar”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Single ticker. Call alphai_insider_news(ticker=""). If the user

What it can do on your machine
Read from SKILL.md and the folder at commit 5bd4f16. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Insider Radar loads about 547 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 254 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- 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
- Single ticker. Call
alphai_insider_news(ticker="<SYM>"). If the user wants only the strongest signal, raise the floor withmin_relevance=8. - Watchlist. Call
alphai_insider_news(ticker=...)once per name. If the user gave none, callalphai_insider_news()unfiltered for the broad tape. - Time-box on request. For "this week" / "since earnings", pass
from_date(ISO, UTC). Paginate withcursoronly if they ask for more. - 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.
