Get Fantasy Draft Results

fantasy_get_draft

Read-onlyIdempotent

Draft results: picks with round/overall, team, player, and auction bid where applicable. Pass season for a past year's draft ("show my draft from last year"). Profile-first: league inferred when connected; player names resolved automatically.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`sport`	No	Sport, e.g. 'NFL', 'NBA', 'MLB', 'NHL'. Required for ESPN/Sleeper and Fantrax name lookups.
`season`	No	Season year, e.g. 2025. Required for ESPN/Sleeper league discovery; ignored by Fantrax.
`provider`	No	Fantasy platform. Optional: defaults to your connected platform ('sleeper').
`league_id`	No	The platform's league id (Fantrax also accepts the full league URL).
`credentials`	No	Per-call credentials, only needed WITHOUT a connected profile. Keys: secret_id (Fantrax); espn_s2 + swid (private ESPN leagues); username or user_id (Sleeper discovery); session_cookie / auth_token + write_enabled:true (explicit write opt-in only). Public ESPN leagues and all Sleeper reads need none.
`league_query`	No	League name/id filter, for when the profile has several leagues on the provider.
`response_format`	No	'markdown' (default) or 'json' (raw payload).	markdown

TDQS

A4.4/5.0

Behavior4/5

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

Annotations already cover read-only/idempotent behavior. The description adds non-schema value: profile-first league inference, automatic player-name resolution, and season-based lookup for past drafts.

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

Conciseness5/5

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

Two tight sentences: the first states the result shape, the second gives usage examples and behavior. Key information is front-loaded with no repetition of schema details.

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

Completeness4/5

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

Given full schema coverage and an annotations safety profile, the description supplies what is missing: output fields, profile-first behavior, and past-season usage. It does not route against sibling tools, but sibling names make that less critical.

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

Parameters4/5

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

Schema covers all 7 parameters in depth, so the description is free to add only natural-language meaning: season as 'show my draft from last year' and 'where applicable' for auction bids. This modestly exceeds the schema.

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?

States a specific verb and resource: returns draft results with picks (round/overall), team, player, and auction bid where applicable. This clearly distinguishes it from sibling tools like rosters, standings, or schedule.

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

Usage Guidelines4/5

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

Provides clear invocation context: pass season for a past year's draft and rely on profile-first league inference when connected. Does not explicitly name alternatives or exclusions, but the usage is concrete and actionable.

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