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

Annotations cover only the basic write/non-open-world safety profile; the description adds materially more: it creates a persistent venture with side effects, requires filesystem access, is blocked in chat-app contexts, and is quota-bound (max 30 cards and only one venture on the Free plan). These are exactly the constraints an agent needs before committing to a write.

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 a one-sentence outcome summary, then a numbered workflow and a closing paragraph of limits. Every sentence carries information, though the steps are verbose enough that a shorter imperative form would read faster. No filler or 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?

For a 4-required-param creation tool with no output schema, the description covers prerequisites, quotas, and expected input quality thoroughly. Its one gap is that it never says what the call returns (venture id/URL) or what happens if the one-venture limit is already hit, which an agent cannot infer from structured fields.

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 100%, so the baseline is 3, and the description goes beyond it by specifying semantic shape: 10-40 features total, plain-language user-facing phrasing, at most 5 self-added planned features (declared as such), and stack limited to one or two lines. It doesn't add per-field constraints the schema lacks, but it meaningfully guides how to populate them.

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 opening sentence states a specific verb and resource ('Turns the project you're working in into a new Flowmaps venture') and immediately enumerates the resulting artifacts: a mind map of features marked Shipped, plus the tech stack as a skill. No sibling tool does anything comparable, so an agent can distinguish it at a glance.

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?

It gives an explicit three-step pre-flight protocol (read the repo files, enumerate features with statuses, get user confirmation) and then states 'Only then call this tool.' It also names the alternatives for non-repo input ('If the user gave a GitHub address instead, clone it first') and the environmental precondition (won't work from a chat app).

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