unsubscribeCancel a subscription by id. Ownership is enforced — you can only cancel your own subscriptions. The row is deactivated (not deleted) so its historical events stay available via recent_alerts.
| Name | Required | Description | Default |
|---|---|---|---|
| id | Yes | Subscription id (uuid) returned by subscribe. |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Adds ownership enforcement and deactivation behavior beyond annotations. Aligns with idempotentHint and destructiveHint. No contradictions.
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, each essential: purpose and behavioral constraints. No wasted words.
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?
Fully addresses purpose, preconditions (ownership), side effects (deactivation, history), and ties to sibling recent_alerts. Adequate for a single-param 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?
Description repeats schema's parameter description but adds no new semantic context. Full schema coverage justifies baseline 3.
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?
Explicit verb 'Cancel' with resource 'subscription by id'. Distinguishes from siblings like subscribe (creates) and list_subscriptions (lists).
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?
Clearly states ownership enforcement and that cancellation is deactivation not deletion, with direction to recent_alerts for history. Could be stronger with explicit when-not-to-use but suffices.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

The ask_pipeworx family (ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded) is highly overlapping—two of them are explicitly identical right now—and the six polymarket_* tools plus bet_research create unclear boundaries between prediction-market analysis tools. Company-focused tools (entity_profile, compare_entities, recent_changes, resolve_entity) also partially overlap in what they fetch, making tool selection error-prone.
Most tool names follow a clear snake_case pattern with descriptive verbs (search_quotes, resolve_entity, validate_claim, subscribe, unsubscribe). There is good use of family prefixes like polymarket_* and pipeworx_*, though the Pipeworx family mixes prefix and suffix placement (ask_pipeworx vs. pipeworx_feedback), which is a minor inconsistency.
35 tools is far too many for a server named 'Quotable', especially since only 4 tools (get_authors, list_tags, random_quote, search_quotes) relate to quotes. The rest span data lookup, prediction markets, memory, subscriptions, AI visibility, and dependency scanning—an extremely broad, unfocused scope that overwhelms the apparent purpose.
The quote-related surface is minimal but functional (random, search, authors, tags), though missing obvious operations like get_quote_by_id. The data-lookup and prediction-market domains are thoroughly covered with grounding, research, arbitrage, and fill-risk tools, so the broader set is complete—but it does not serve the server's stated identity as a quotes provider.
