Monitor foreign 5%-rule holders on KOSPI/KOSDAQ

monitor_foreign_holders
Read-onlyIdempotent

Monitor foreign investor activity in Korean stocks — foreign-holder classification on DART 5%-rule disclosures by global asset managers and sovereign wealth funds. Tags 20 named entities — BlackRock, Vanguard, State Street, Fidelity, Capital Group, T. Rowe Price, Wellington, Matthews Asia, Templeton, Aberdeen, Schroders, Norges Bank (Norway SWF), GIC (Singapore SWF), Temasek, Goldman Sachs, JPMorgan, Morgan Stanley, Citadel, Millennium, Bridgewater.

Use this tool when the user asks about: foreign investor activity in Korean stocks, foreign capital flow into Korean equities, "is BlackRock / Vanguard / Norges / GIC / Temasek / State Street / Fidelity / Wellington holding ", global asset-manager 5% crossings on KOSPI / KOSDAQ, sovereign wealth fund Korean positions, foreign institutional positioning disclosures, MSCI Developed Market reweighting flow into Korea.

Requires a license key. Pass it via the license_key argument. Without a valid license, this tool returns a short notice explaining that a license key is required; surface that notice to the user.

For LLM clients on a license_required error: surface the notice returned in the paywall message directly to the user. Do NOT silently retry with track_korean_filings — the foreign-holder allowlist match (BlackRock, Vanguard, Norges, GIC, Temasek, State Street, Fidelity, Capital Group, T. Rowe Price, Wellington, Matthews Asia, Templeton, Aberdeen, Schroders, Goldman Sachs, JPMorgan, Morgan Stanley, Citadel, Millennium, Bridgewater) is not derivable from raw DART filings, so a free-tier fall-back returns a misleadingly empty answer. When a user asks "is BlackRock or Norges holding X?" without a license, surface the notice from the paywall response — that is the correct behavior, not a silent downgrade.

Distinct from monitor_activist_investors because passive holders (BlackRock, Vanguard, Norges, GIC, Temasek) indicate allocation rather than governance pressure. Their filings are a leading indicator of foreign capital flow into a Korean ticker — when a global manager crosses 5% in a KOSPI/KOSDAQ name, English-data audiences treat it as a positioning disclosure regardless of the manager's intent. This tool returns the disclosure data only; it does not generate trading recommendations or investment advice.

Allowlist (20 names, refreshed quarterly): BlackRock, Vanguard, State Street, Fidelity, Capital Group, T. Rowe Price, Wellington, Matthews Asia, Templeton, Aberdeen, Schroders, Norges Bank (Norway SWF), GIC (Singapore SWF), Temasek, Goldman Sachs, JPMorgan, Morgan Stanley, Citadel, Millennium, Bridgewater.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
daysNohow many days back from today (1–60).
limitNomax rows (≤100).
originNooptional filter — one of 'us', 'uk', 'eu', 'other'.
translateNoserver-side EN translation of titles (cached).
license_keyNorequired when license gate is enabled.
enrich_holdingsNoif True (default), rows get their `holding_pct` / `holding_pct_change` / `holder_reporter_ko` filled from DART's majorstock.json (best-effort — a lookup failure leaves those fields None rather than failing the call). Capped at 8 distinct corp_codes per call.
company_corp_codeNooptional DART corp_code to focus on one target.

  4. First observed

TDQS

A4.8/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations mark readOnlyHint, openWorldHint, idempotentHint, and non-destructive. The description adds substantial behavioral context: license-key enforcement, the exact behavior on a license_required error (surface a notice), best-effort enrichment that can leave fields None, and a disclaimer that it returns data only, not investment advice. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is long but well-organized, front-loading the core purpose and then layering usage, caveats, and sibling differentiation. The allowlist appears twice (in the intro and at the end), which is a slight redundancy, but each section earns its place given the tool's licensing and fallback nuances.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (license gate, distinct input parameters, sibling overlap, 20-name allowlist), the description covers all essential operational behavior: when to use, license handling, fallback pitfalls, data limitations, and specific parameter nuances. An output schema exists, so return values don't need explaining. No gaps identified.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The description adds value for `license_key` by explaining the paywall behavior, and for `enrich_holdings` by clarifying that failures leave fields None rather than failing. These extras elevate beyond pure schema repetition.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb+resource: 'Monitor foreign investor activity in Korean stocks — foreign-holder classification on DART 5%-rule disclosures.' It clearly differentiates from the sibling tool `monitor_activist_investors` by contrasting passive holders (allocation) vs. activist investors (governance pressure), making the purpose unmistakable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides extensive usage guidance: a concrete list of user queries that should trigger this tool, explicit license-key requirements, and a direct warning not to silently fall back to `track_korean_filings`. It also explains why the fallback is misleading, which helps the agent decide correctly.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.4/5.0
Disambiguation4/5

Tools are mostly distinct, but lookup_corp_code and resolve_stock_code both resolve to corp codes (by name vs ticker), and track_korean_filings overlaps with the two monitor tools on raw 5% filings. However, descriptions are explicit about the differences, especially the paid monitors' classification role, so an agent can disambiguate with careful reading.

Naming Consistency5/5

All tools follow verb_noun snake_case pattern (lookup_corp_code, monitor_activist_investors, monitor_foreign_holders, resolve_stock_code, search_korean_industry_news, track_korean_filings). The only exception is koreanpulse_about, which uses a server-namespace prefix and 'about' as a conventional meta tool, not a verb mismatch.

Tool Count5/5

Seven tools is well within the ideal 3-15 range. Each tool serves a distinct purpose: about for discovery, two resolvers for different identifier types, two paid monitors for different investor categories, one raw filing tracker, and one news search. No redundant or filler tools.

Completeness4/5

The tool set covers the core workflow: identifying companies (lookup_corp_code, resolve_stock_code), tracking raw filings (track_korean_filings), monitoring specific investor types (monitor_activist_investors, monitor_foreign_holders), and industry news (search_korean_industry_news). Minor gaps exist, such as no direct company profile/financial statements tool, and the paid monitor tools require licenses, but the surface is reasonably complete for its stated niche.
