initialize_deck

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

With no annotations, the description must carry the behavioral burden. It usefully discloses that the result is an 'isolated' workspace and that there is 'No API call' (a non-obvious, valuable trait). It does not say what happens on a name collision, whether it is idempotent, what files/directories it writes, or what identifier is returned for later tools.

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?

Front-loaded with the action and resource in one sentence, followed by a short parameter note and a behavioral aside. Every sentence carries information, though the block layout (indented parameter note plus trailing sentence fragment) is slightly choppy.

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?

There is no output schema and no annotations, so the description is the only source of truth. It explains creation and scoping but never says what the tool returns (a workspace id/path?) or how that value feeds the downstream deck tools, which an agent needs to chain calls correctly.

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?

Schema coverage is 0%, so the description must compensate, and it largely does: `visual_system` is explained as selecting a folder under visual-systems/ with an explicit default when omitted, and `input_path` is constrained to 'one Markdown file under input/'. What is missing is the exact format/expectations for input_path (relative vs absolute, extension).

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?

The description gives a specific verb and resource: 'Create an isolated output workspace from one Markdown file under input/.' That is far more precise than the bare tool name, and it conveys the pipeline role. It does not name or differentiate itself from siblings (e.g., 'call this before submit_deck_plan'), so it stops short of a 5.

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?

Usage is implied by 'create ... workspace' and the per-parameter note about `visual_system`, suggesting this is the entry point of the deck workflow. However, there is no explicit statement of when to call it versus siblings like `list_visual_systems`, nor any prerequisite (does a plan need to exist? must it be called once per deck?). Guidance is inferred, not stated.

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