FREE. Service health and how recently the data was refreshed. Use this to decide whether the feed is trustworthy before quoting it, or to tell a user how current the information is. Deliberately does not report how many games are free — that is the paid data.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description effectively carries the behavioral disclosure burden. It mentions the tool is 'FREE' and deliberately does not report free game counts, which is a limitation. However, it doesn't detail the response format or any other behavioral aspects, but for a status tool this is adequate.
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 three sentences with minimal waste. It front-loads the core purpose, then provides usage guidance and a clear limitation, all in a compact, well-structured 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?
Given the tool's simplicity (zero params, no output schema), the description is complete. It covers what the tool does, when to use it, and what it deliberately excludes, giving an AI agent enough context to select and invoke it correctly.
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?
The tool has zero parameters and the schema is empty (100% coverage), so the baseline for parameter semantics is 4. The description adds no direct parameter information but clarifies the tool's scope, which reduces ambiguity about what arguments might be needed.
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 tool provides 'service health and how recently the data was refreshed,' identifying the specific resource and scope. It also distinguishes itself from siblings by explicitly noting what it does NOT do (report free game counts), which clarifies its unique role.
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 gives explicit guidance on when to use the tool ('before quoting it, or to tell a user how current the information is') and explicitly excludes the use case of counting free games, directing users to paid data. This provides clear context and a when-not-to-use signal.
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.
Each tool has a clearly distinct purpose: checking for changes, listing current free games, getting a game's price, checking service status, discovering upcoming giveaways, and resolving game names to identifiers. There is no meaningful overlap between them.
All tool names follow a consistent verb_noun snake_case pattern: check_for_changes, get_free_games, get_game, get_status, get_upcoming, lookup_game. The verbs are clear and the style is uniform.
The server has 6 tools, which is well-scoped for its purpose of providing game deals, free games, and pricing information. Each tool earns its place and there is no bloat or redundancy.
The tool set covers the full lifecycle of a typical user query: lookup a game, check its price, see current free games, check upcoming giveaways, verify data freshness, and avoid unnecessary paid calls via change detection. There are no obvious dead ends.
