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

With no annotations, the description carries the burden and does meaningful work: it discloses the approval workflow ('Log entries you write are drafts until they approve them'), that the agent acts on behalf of a human builder, and an anti-fabrication constraint. It omits auth/ownership requirements (sibling verify_ownership exists and goes unmentioned) and what happens on duplicate creation.

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 most sentences carry operational weight. The 'poker players building startups' framing justifies the tone expected in tagline/description, but it slightly defers the procedural rules, and the draft/approval point is stated twice in near-duplicate form.

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 an 8-parameter mutation tool with no annotations and no output schema, this covers the essentials: how to source values, the human-approval gate, and a no-fabrication rule. Missing is any statement of what is returned, how duplicates are handled, or the relationship to verify_ownership/start_signup.

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 baseline is 3; the description adds real value by telling the agent where each value should come from — repo, package.json, live https URL — rather than inventing them. It does not touch status, looking_for, or revenue_model handling, which the schema already covers well.

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?

States a specific verb and resource — 'Put the project you are working on onto R2F' — and names the concrete fields to gather (name, tagline, URL, stack). It is clearly distinguishable from post_update and update_build by implication of first creation, though it never names those siblings explicitly.

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?

Gives concrete preconditions and workflow: read the repo for real data, show the human the draft before posting, ask rather than invent. It does not state when to use update_build instead (e.g. if the build already exists), which is the one routing decision an agent would most need.

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