Get personalized game recommendations

get_recommended_games

Read-only

Recommends unowned Steam games by weighting tags from a player's most-played owned games, ranked by review score and discount. Use exclude_tags and min_discount to refine.

Instructions

Recommend unowned Steam catalog games personalized to this player: tags on their own most-played owned games become weighted preferences (more playtime on a tag = more weight), discounted by each candidate's review score so a tag match on a poorly-received game doesn't outrank a better one, then ranked against a broad catalog page, excluding anything already owned. based_on_tags shows which of the player's own top tags drove the ranking; each result carries matched_tags and match_score alongside the usual price/review/compat card. Set exclude_tags to steer away from a genre despite it matching by playtime, and/or min_discount for a minimum deal size (e.g. 'suggest games on sale, not RPGs or shooters' → exclude_tags:['RPG','Shooter','FPS'], min_discount:30). Different from discover_games (which needs YOU to name the filters) — this infers taste from the player's WHOLE library instead, for 'what should I play next' / 'recommend me something'. For 'something like THIS ONE game' (a single named title), get its tags via get_items and call discover_games with them instead. Recommends base games only — DLC, soundtracks and demos are never suggested, the same filter discover_games applies. Note: taste is weighted from only the player's 30 most-played owned games, and candidates come from a fixed 300-entry catalog scan, so a heavy exclude_tags/min_discount combination can return fewer than limit — there's no larger scan to fall back to. Requires STEAM_API_KEY and a public profile with game-details visible (same requirement as get_owned_games) — found:false is also returned if the player owns no games at all, or if too few of their played games have resolvable tags to build a taste profile.

Input Schema

TableJSON Schema

Name	Required	Description
`limit`	No	How many recommendations to return (1-25). Default 10.
`steamid`	No	17-digit SteamID64. Omit to use the STEAM_ID configured on the server. Convert a vanity/custom URL name with resolve_vanity_url first.
`exclude_tags`	No	Drop any candidate carrying ANY of these tags (case-insensitive), e.g. ['Souls-like'] for 'recommend me something except Souls-like'. Use exact Steam tag names — a misspelled/unrecognized one isn't an error, it just drops nothing.
`min_discount`	No	Minimum discount %, e.g. 30 for '30%+ off'. Omit to include full-price games too. Filtered server-side and re-checked client-side, so it holds at any value including 100.

TDQS

A4.9/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations only declare readOnlyHint and openWorldHint, but the description adds rich behavioral detail: the 30 most-played games weighting, fixed 300-entry catalog scan, possibility of fewer results than limit, requirements for STEAM_API_KEY and public profile, and failure modes (found:false). It also describes result fields (matched_tags, match_score, based_on_tags) and the base-games-only filter. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is long but every sentence carries meaning: algorithm, differentiation, examples, limitations, and error conditions. It is front-loaded with the core purpose and then layers details. Slightly dense but not redundant; it could be tightened but remains efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity, the description covers purpose, usage, parameters, output fields, limitations, prerequisites, and edge cases. The output schema exists (so return format is partly structured), but the description adds the algorithmic context and failure modes. Nothing essential is missing for an agent to call it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3, but the description adds significant value: it explains the purpose of exclude_tags with an example ('steer away from a genre despite it matching by playtime'), clarifies min_discount semantics with an example, and notes that limit may be under-filled due to the fixed catalog scan. This goes well beyond the schema's plain parameter definitions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a precise statement: 'Recommend unowned Steam catalog games personalized to this player', then explains the recommendation algorithm (weighted tags, review-score discount) and explicitly distinguishes itself from discover_games. The verb, resource, and personalization are all clear, and the differentiation from siblings is direct.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly states when to use this tool ('what should I play next' / 'recommend me something') and when not to ('something like THIS ONE game' → use get_items + discover_games instead). It also provides a concrete example with exclude_tags and min_discount. This is exemplary guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
