tools

Package docling groups the explicit, agent-invocable tools built on docling-serve: read_document_url (fetch+convert a remote document) and docling_convert (convert a local file that native extraction can't handle well - scanned PDFs, complex slide decks, audio).

Package docx provides find/replace editing for DOCX documents: the write-side counterpart to internal/officetext's native DOCX read support, the same relationship internal/tools/files/excel has to XLSX.

Package excel provides a structured cell-range editor for XLSX spreadsheets, the write-side counterpart to internal/officetext's native XLSX read support.

Package pdfwrite provides the write_pdf tool: creating a new PDF from plain/markdown-ish text, appending text as new page(s) to an existing PDF, and deleting pages from an existing PDF.

Package searchsession provides a cancellable, streaming search: unlike the grep/glob tools (which block until ripgrep finishes and return everything at once), search_start spawns ripgrep as a background job and returns immediately with a job_id - job_output (offset/tail-capable, see internal/tools/bash) paginates through matches as they accumulate, job_kill cancels a search that's taking too long or targeting too much, and task_list shows what's running.

Package calculator provides a calculator tool for basic arithmetic, advanced mathematical functions, and expression evaluation.

Package financial provides a financial calculation tool.

Package hackernews provides tools for the Hacker News public API.

Package reddit provides tools for Reddit via the official REST API.

Package twitter provides tools for Twitter/X via the v2 API.

Package config provides the get_config tool: a read-only view of seshat's effective security policy (the same values write_file, bash, and every other write-capable tool actually enforce, not a separately maintained description of them), mirroring DesktopCommanderMCP's get_config.

Package fimtool exposes Fill-in-the-Middle code completion as a Seshat tool.

Package goal implements create_goal, get_goal, and update_goal tools.

Package mailbox provides tools for inter-agent communication via the persistent mailbox system.
