Workflow

Resolve to
```
<CODE>.<MARKET>
```
. Reject US-only subcommands for non-US, HK-only for non-HK — explain politely.
Pick subcommands by prompt cue. Don't run all of them by default.
Call concurrently when the question is "全景资金面" style.
Summarise direction (net buying / net selling), top names, freshness (report date).
Cite Longbridge Securities (and SEC EDGAR for
```
insider-trades
```
/
```
investors
```
).

If

--help

shows newer flags, follow the help output rather than hard-coding here.

Output

Render in the user's language. Suggested layouts:

13F (
investors
) — when no CIK: AUM-ranked manager table. With CIK: top-N positions (ticker / value / shares / weight / change vs last filing). For

changes

: NEW / ADDED / REDUCED / EXITED grouped lists.

fund-holder
— table sorted by weight: fund name / ticker / currency / weight % / report date. Highlight high-weight funds (> 1%).

insider-trades
— chronological list (most recent first): date / insider / role / type (BUY/SELL/GRANT/...) / shares / price / value. Net buy vs sell summary at top.

short-positions
— time-series table: date / short interest / short ratio / days-to-cover. Note trend (rising / falling).

broker-holding
— for the

--period

view: top buy brokers and top sell brokers side by side. For

detail

: full list. For

daily

: a single broker's history.

When a result is empty, state so. Do not invent.

Error handling

Situation	Reply
Shell `command not found: longbridge`	Fall back to MCP if configured; otherwise tell the user to install longbridge-terminal.
Non-US symbol passed to `insider-trades` / `short-positions`	Reply "This subcommand only supports US-listed equities."
Non-HK symbol passed to `broker-holding`	Reply "Broker holding is HK-only."
Empty result	State explicitly. Do not invent.
Other stderr	Relay verbatim — never silently retry.

MCP fallback

When the CLI binary is missing, fall back via the equivalent MCP tool. Tool names typically mirror CLI subcommand names (snake_case).

CLI subcommand	MCP tool
`investors` (rankings / 13F)	`mcp__longbridge__investors`
`investors changes`	`mcp__longbridge__investors_changes`
`fund-holder`	`mcp__longbridge__fund_holder`
`insider-trades`	`mcp__longbridge__insider_trades`
`short-positions`	`mcp__longbridge__short_positions`
`broker-holding`	`mcp__longbridge__broker_holding`
`broker-holding detail`	`mcp__longbridge__broker_holding_detail`
`broker-holding daily`	`mcp__longbridge__broker_holding_daily`

If a name above does not resolve, fall back via the equivalent MCP tool when CLI is missing.

Related skills

Skill	Why
`longbridge-corporate`	Major shareholder % structure (a different lens than 13F flow).
`longbridge-capital-flow`	Today's intraday large/medium/small-order distribution.
`longbridge-news`	Filings (8-K / 13D / 13G) often pair with flow events.
`longbridge-fundamental`	Earnings + dividend backdrop for insider context.
`longbridge-quote`	Live price for sizing the flow.
