A small, dependency-free runtime for typed local Python tools with MCP support
Samsarix Core exhibits significant quality gaps across naming, descriptions, and schema consistency. Tool names lack clear verb-noun patterns (e.g., 'increment' appears twice with identical names but different signatures). Descriptions are present but generic and often under 100 characters, failing to explain WHEN to use tools or what distinguishes similar ones. Parameter descriptions exist but lack detail on constraints, ranges, or format expectations. Critical issue: 3 duplicate tool names (check_inventory, reserve_inventory, increment) with overlapping or identical signatures create ambiguity for LLM selection. Schema quality varies, some tools have proper type definitions, others lack detail. No evidence of output schema documentation, error recovery guidance, or idempotency markers. The codebase shows good async/await patterns and progress reporting, but tool definitions themselves are underdeveloped for production agent use.
Count known inventory records while reporting completed work.
Return a deterministic local-cache value unrelated to vendor health.
Apply one safe arithmetic operation to two numbers.
Return available inventory from this example's local catalog.
Read current stock from the host-selected local database.
Return a stand-in for one application-owned vendor API response.
Return a stand-in for one application-owned dependency request.
Duplicate tool names across files: 'check_inventory' appears in sqlite_reservations.py and mcp_inventory_server.py; 'reserve_inventory' appears 3 times with different signatures; 'increment' appears twice. LLMs cannot disambiguate tools with identical names, this violates single-responsibility and clarity principles.
Descriptions are generic and under 100 characters for most tools. 'Return available inventory from this example's local catalog' (check_inventory) lacks context on WHEN to use it vs. cached_inventory or vendor_inventory. No guidance on tool selection or dependencies.
No output schema documentation visible. Tools return dicts but LLMs cannot see what fields to expect (e.g., does check_inventory return {sku, available} or {sku, available, timestamp}?). This forces LLMs to guess field names for downstream tool calls.

Increment an integer.
Increment an integer.
Increment an integer synchronously.
Reserve stock once per request ID; retry only with identical arguments.
Simulate a policy-gated write without modifying inventory.
Return a deterministic reservation-shaped response for protocol demos.
Model a read-only vendor outage without using the network.
Parameter descriptions lack constraint details. 'sku' is described as 'Stock keeping unit identifier' but no format, length, or valid value guidance. 'quantity' lacks min/max bounds. 'operation' in calculate has enum but no description of what each operation does.
No error handling or recovery guidance visible. Tools return dicts but no indication of error cases, retryability, or what the LLM should do if a call fails. No distinction between user-fixable errors and fatal failures.
