Alcove

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Without annotations, description carries full burden and succeeds well: explains template source, distinguishes internal vs external doc creation, and crucially states 'creates all missing' implying idempotent/safe default behavior (complemented by overwrite parameter). Missing only failure modes and return value details.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Four sentences with zero waste. Front-loaded with core purpose, followed by internal docs scope, conditional external docs behavior, and parameter-specific usage. Every sentence advances understanding without redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Comprehensive for a 4-parameter creation tool with no output schema. Covers template source, document types (PRD, Architecture, README, etc.), existence handling ('missing'), and parameter conditionality. Minor gap: no mention of error conditions or return value structure.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Despite 100% schema coverage, description adds valuable workflow context: explains project_path triggers external docs (README, CHANGELOG), files restricts to specific documents, and default behavior creates 'all missing internal required docs'. Explains parameter interactions beyond isolated definitions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Excellent specificity with verb 'Initialize', resource 'documentation', and scope 'from alcove templates'. Clearly distinguishes from siblings like configure_project (settings management) and audit_project (read-only analysis) by emphasizing document creation from templates.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides clear conditional guidance: explains when to provide project_path (to trigger external docs creation) and when to use files parameter (for selective creation vs default 'all missing' behavior). Lacks explicit sibling references as alternatives but explains internal decision logic well.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
