Monitor foreign 5%-rule holders on KOSPI/KOSDAQ

monitor_foreign_holders
Read-onlyIdempotent

Track foreign capital flow into Korean equities via DART 5%-rule disclosures by 20 global asset managers and sovereign wealth funds including BlackRock, Vanguard, and Norges Bank.

Instructions

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 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 paywall message containing the activation URL — surface that message verbatim to the user.

For LLM clients on a license_required error: surface the activation URL 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 activation URL 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.

Behavior4/5

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

Annotations declare readOnlyHint true, destructiveHint false, idempotentHint true. The description adds critical behavioral context: requires a license key, returns a paywall message without a valid license, and does not generate trading advice. It also explains that the allowlist is not derivable from raw DART filings.

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 lengthy but well-structured with clear paragraphs. It front-loads the core purpose, then details usage, error handling, and distinctions. Some repetition exists (allowlist listed twice), but overall it is organized and informative.

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 tool's complexity, the description covers all necessary aspects: purpose, use cases, parameter implications, error handling, and relationship to siblings. The presence of an output schema and clear annotations complement the description well.

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

Parameters3/5

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

Schema coverage is 100%, so the baseline is 3. The description does not add significant detail about parameters beyond what the schema provides, except emphasizing the `license_key` requirement. It confirms the purpose of each parameter indirectly.

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 clearly states the tool monitors foreign 5%-rule holders on KOSPI/KOSDAQ and lists 20 specific entities. It distinguishes itself from the sibling `monitor_activist_investors` by explaining the difference in intent (allocation vs governance pressure).

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 explicit when-to-use scenarios (e.g., foreign capital flow, specific entity holdings) and when-not-to-use (e.g., not for activist). It also gives clear instructions on handling license errors and warns against using a fallback tool.

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