Tools & capabilities
Cairn tools 48
list_dirList files and folders directly under a workspace-relative directory.get_file_treeReturn the nested file/folder tree under a directory (default: whole workspace).read_detailRead a file. For .uni docs returns HTML content, flattened text, and tags; for text/.md files returns raw text plus any YAML frontmatter tags & metadata.search_filesFind files/folders whose name contains `query` (case-insensitive).grepSearch file contents for `pattern`; returns {path, line, text} matches.get_file_tagsReturn a document's tags — from a .uni's tags array or a text file's YAML frontmatter.get_tag_treeReturn {tag: [file paths]} aggregated across the workspace.find_by_metaFind documents whose metadata matches all `filters` (exact, not fuzzy). Reads .uni JSON fields and .md YAML frontmatter alike. Scalar fields match case-insensitively; `tags` (or any list field) matches when every requested value is present. Example: {"status": "to-read", "project": "amazon"}.list_tasksList tasks (documents with `category: task`), sorted by due date. A task is an ordinary frontmatter note with a lifecycle; this is the task view over it. `status` defaults to the open set (todo/doing/blocked) — pass "all" to include done, or a specific status / comma-separated list. `project` and `context` (e.g. "@errand") are exact case-insensitive filters; `due_before` (YYYY-MM-DD) keeps only tasks due before that date. Each result carries derived `overdue` and `today` flags relative to the current date.digest_workspaceReturn a token-efficient map of the workspace: one entry (title, date, tags, summary) per document, grouped by `folder`, `tag`, or a metadata field like `status`/`project`. Read this before loading individual files.list_templatesList available document templates (built-ins + workspace .cairn/templates).semantic_retrieveReturn the documents most relevant to `query`. Uses embeddings when an embedding endpoint is configured (env), else lexical scoring.- +36 more on the listing page
