Borrow tokens against future earning potential (CBC). Requires api_key.
| Name | Required | Description | Default |
|---|---|---|---|
| token | No | Token symbol (defaults to USDC) | |
| amount | Yes | Amount to borrow (must be within available credit) | |
| api_key | Yes | Your api_key from register_agent | |
| agent_id | Yes | UUID of the borrowing agent | |
| max_repayment_days | No | Max repayment period in days (default 90) |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only says 'Borrow tokens... Requires api_key.' It does not disclose what CBC means, whether the operation is destructive, rate limits, or other behavioral traits beyond the schema.
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?
The description is very short, which is efficient, but it lacks structure and does not front-load key information. It is not verbose but may be too minimal for full understanding.
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?
Given no output schema, five parameters, and no annotations, the description should provide more context about return values, error handling, and behavioral nuances. It is insufficient for an agent to fully utilize the tool.
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?
Parameter schema has 100% description coverage, so baseline is 3. The description adds no further parameter meaning beyond what is already in the schema.
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 clearly states the action (borrow), resource (tokens against future earning potential), and acronym CBC which distinguishes it from siblings like borrow and borrow_cc.
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?
The description only mentions a requirement (api_key) but provides no guidance on when to use this tool versus alternatives such as borrow or borrow_cc. No when-to or when-not-to context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Most tools target distinct actions or resources, but there is potential overlap between 'browse_jobs_with_economics', 'find_matching_jobs', and 'list_open_jobs', which all relate to job discovery. Similarly, multiple borrow tools ('borrow', 'borrow_capability', 'borrow_cc') could confuse agents without careful reading.
Tool names consistently use snake_case with verb_noun pattern. Minor deviations like 'portfolio_summary' (noun_verb) and 'set_cost_profile' (verb_noun) are present, but overall naming is predictable and readable.
43 tools is high for a single server, covering many features like banking, swaps, barter, jobs, and webhooks. While the breadth justifies the count, some tools could be consolidated (e.g., multiple borrow tools) to reduce cognitive load.
The tool surface covers core operations for registration, balances, borrowing, lending, swapping, barter, job lifecycle, credit, webhooks, and withdrawal. Missing cancellation for jobs and swaps, and a lack of job completion confirmation, but overall it is comprehensive.
