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 declare readOnlyHint, idempotentHint, and non-destructive. Description adds return field details (id, type, etc.) and default behavior (active only), but doesn't cover potential errors or limits.
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 concise sentences: first covers purpose and return fields, second provides usage guidance. Efficient and front-loaded.
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?
Description explains return fields (compensating for lack of output schema) and usage context. Lacks details on pagination or errors, but sufficient for a simple list operation.
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 description coverage is 100% for the single parameter; description does not add extra information about parameters beyond what the schema already provides.
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?
Description clearly states the verb 'list' and the resource 'subscriptions', specifies 'caller's active subscriptions' which distinguishes from sibling tools like subscribe and unsubscribe.
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 tells when to use the tool: 'review what you're monitoring before adding more or to find an id to cancel', providing clear context for invocation.
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 have distinct purposes, but several clusters overlap: ask_pipeworx_beta is currently identical to ask_pipeworx, polymarket_arbitrage and polymarket_edges both surface arbitrage opportunities, and validate_claim overlaps with ask_pipeworx_grounded. Descriptions mitigate some confusion, but selection errors are still likely.
Names are overwhelmingly lowercase snake_case and descriptive, such as nist_control_family, polymarket_fill_risk, and list_subscriptions. Minor deviations exist with single-word memory verbs like remember/recall/forget and the ask_pipeworx_* variants, but the overall pattern is predictable and readable.
34 tools is well above the comfortable range and includes many tools unrelated to the server's NIST Standards name, such as Polymarket betting, npm dependency scanning, AI visibility checks, and llms.txt generation. The set feels like a broad general-purpose data platform rather than a scoped NIST reference server.
For the NIST domain, the three control tools provide id lookup, family listing, and keyword search, but there is no catalog overview or family enumeration, and no comparison, revision, or export capability. The other 31 tools do not fill those gaps, so the NIST surface is functional but not fully complete for compliance workflows.
