list_subscriptionsList the caller's active subscriptions. Returns id, type, params, created_at, last_fired_at, fire_count for each. Use this to review what you're monitoring before adding more or to find an id to cancel.
| Name | Required | Description | Default |
|---|---|---|---|
| include_inactive | No | Include cancelled subscriptions in the response (default false). |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint and idempotentHint. Description adds that it returns only the caller's subscriptions and specific fields, which is useful context beyond annotations.
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?
Two sentences, front-loaded with purpose and return format, followed by usage guidance. No extraneous information.
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 simple read-only list tool with one optional parameter and annotations covering safety, the description fully covers what returns, when to use, and default behavior.
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 covers 100% of the single parameter 'include_inactive' with its own description. Description adds no additional parameter details beyond implying active subscriptions by default.
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?
Clearly states it lists the caller's active subscriptions and enumerates return fields. Distinguishes from siblings like 'subscribe' and 'unsubscribe' by specifying its purpose as review and id retrieval.
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?
Explicitly advises when to use: 'before adding more or to find an id to cancel.' Provides clear context but no explicit when-not-to-use, though not necessary for this tool.
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.
Several tools have overlapping purposes: ask_pipeworx, ask_pipeworx_beta, and ask_pipeworx_grounded are very similar, as are the suite of polymarket_* tools. While descriptions help differentiate, an agent may struggle to choose the correct one without careful reading.
All tool names use snake_case, but they mix verb-first patterns (ask_pipeworx, compare_entities, validate_claim) with noun-first patterns (bet_research, entity_profile, pipeworx_feedback). This inconsistency makes it harder to guess tool names by convention.
35 tools is on the high side but not unreasonable for a platform covering vulnerability queries, data retrieval, prediction markets, and utilities. However, the server name 'Osv' suggests a narrow focus, making the large count feel bloated.
The tool set covers a wide range of operations: querying data, comparing entities, managing user data, monitoring subscriptions, and even onboarding. Minor gaps exist (e.g., no direct API for updating user profiles), but overall it is well-rounded for its domain.
