Instructions

Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

Tools

Functions exposed to the LLM to take actions

NameDescription
arcana_add_resourceB

Add a file or directory as a resource into the context database.

Args:
    path: Local file or directory path to index.
    to: Target arcana:// URI (optional, auto-determined if empty).
    reason: Why this resource is being added.
arcana_lsB

List direct children at a arcana:// URI.

Args:
    uri: arcana:// URI to list (default: root).
arcana_treeB

Show recursive tree at a arcana:// URI.

Args:
    uri: arcana:// URI to show tree for (default: root).
arcana_statC

Get metadata for a resource.

Args:
    uri: arcana:// URI to get metadata for.
arcana_rmA

Remove a resource (CASCADE deletes chunks, FTS triggers clean up).

Args:
    uri: arcana:// URI to remove.
    recursive: Remove all resources under this URI prefix.
arcana_findA

Semantic search — embed query, cosine similarity against all chunks.

Args:
    query: Natural language search query.
    target_uri: Scope search to a specific arcana:// URI prefix (optional).
    limit: Max number of results (default 10).
arcana_grepB

Keyword/regex search — FTS5 for simple terms, Python re fallback.

Args:
    uri: arcana:// URI to search within.
    pattern: Search pattern (keyword or regex).
    case_insensitive: Case-insensitive matching.
arcana_searchA

Hybrid search — 0.7 * semantic + 0.3 * FTS5, merged and ranked.

Args:
    query: Natural language search query.
    target_uri: Scope search to a specific arcana:// URI prefix (optional).
    limit: Max number of results (default 10).
arcana_readB

Read full content of a resource (concatenated chunks in order).

Args:
    uri: arcana:// URI to read.
arcana_add_memoryB

Store a memory entry as a resource with embedding.

Args:
    role: Memory role (e.g. 'user', 'assistant', 'system').
    content: The memory content to store.
arcana_mkdirA

Create a directory at a arcana:// URI.

Args:
    uri: arcana:// URI for the new directory.
arcana_mvC

Move/rename a resource.

Args:
    from_uri: Source arcana:// URI.
    to_uri: Destination arcana:// URI.

TDQS

A3.7/5.0

Scored across 12 tools

Disambiguation5/5

Each tool has a distinct purpose: memory vs resource addition, different search modes (semantic, keyword, hybrid), and clear navigation vs content operations. No ambiguity.

Naming Consistency5/5

All tools follow the consistent pattern 'arcana_verb' or 'arcana_verb_noun' with snake_case (e.g., arcana_add_memory, arcana_ls, arcana_search). Conventions are uniform.

Tool Count5/5

12 tools is well-scoped for a hierarchical resource and memory system, covering CRUD, navigation, search, and metadata retrieval without bloat.

Completeness4/5

Covers addition, reading, deletion, movement, search, and listing. Missing an update/modify tool for resources or memory, which is a minor but notable gap.
