Tools
Functions exposed to the LLM to take actions
| Name | Description |

| search_subsidiesA | Search Jグランツ subsidies by keyword and filters. Returns one page of summaries with each subsidy's id and portal_url; total_count and next_offset tell whether more pages exist. |
| get_subsidy_detailA | Get one subsidy's full details: overview, eligibility, subsidy rate, amounts, dates, portal_url, and a list of its attachments (read them with read_attachment). |
| read_attachmentA | Read an attachment's text (PDF, page by page) in pieces of max_chars; continue from next_offset. pages_without_text lists PDF pages that are images only. Other formats cannot be read here. |

Scored across 4 tools
Each tool maps to a clearly distinct step: reading usage guidance, searching subsidies, fetching full details, and reading attachments. There is no overlap in purpose, and the descriptions make the intended sequence explicit.
All four tools use a consistent snake_case verb_noun pattern: load_guideline, search_subsidies, get_subsidy_detail, read_attachment. The naming is predictable and readable.
Four tools are exactly sufficient for a read-only subsidy lookup workflow: guidance, search, detail, and attachment reading. No tool feels redundant or missing from the core scope.
The surface covers the main lifecycle from search to detail to attachment reading, plus onboarding guidance. Minor gaps remain around discovering available filters/categories and reading non-PDF attachments, but agents can work around these limitations.
