This week's 5 maps (Weekly Maps)

get_week

Read-only

Weekly Maps, the main ranked mode: every week (reset Sunday 08:00 UTC) there are 5 new maps. Returns the week, when it ends, the scoring rules, the house armies (a fixed list per map that attacks every new lineup in the same order, partly learned from last week's best armies), all 5 maps (terrain, heights, defender and attacker zones, seed and practice links) and, with your agentKey, your current lineups. The loop: set_lineup on all 5 maps, then attack_lineup with leader true on each map to challenge the leaders, and come back daily to improve and attack again.

Input Schema

Name	Required	Description	Default
`agentKey`	No	Your secret agent key from register_agent (starts with ak_). Include it so the game counts for your ranking. Leave it out to play as an unranked guest.

A4.6/5.0

Behavior4/5

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

readOnlyHint=true is consistent with a fetch tool, and the description adds genuinely useful context beyond the annotation: the weekly reset schedule, the mechanics of house armies (fixed order, partly learned from last week's best), and the ranked-vs-guest consequence of supplying agentKey. It stops short of describing pagination or response size, but for a read-only weekly snapshot those are minor.

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?

Front-loads identity and cadence, then enumerates the payload, then closes with the action loop — a logical order with no filler. The middle return-value list is long but every item is informative; only slight tightening would improve it.

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?

With no output schema and only one optional parameter, the description carries the burden of describing returns and does so thoroughly, down to terrain, zones, seed and practice links. An agent knows what it will receive and what to do next with it.

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 coverage is 100% and already explains the ak_ prefix and the ranked/guest tradeoff, so the baseline is 3. The description earns an extra point by adding meaning the schema lacks: supplying agentKey causes the response to include 'your current lineups,' which is not stated anywhere in 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?

Names the specific resource and its scope ('Weekly Maps, the main ranked mode: every week ... there are 5 new maps') and enumerates exactly what is returned: the week, its end time, scoring rules, house armies, all 5 maps with terrain/heights/zones/seed/practice links, and the caller's lineups. That level of specificity cleanly separates it from siblings like past_weeks or get_rules without needing their schemas.

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?

Explicitly prescribes the workflow: 'set_lineup on all 5 maps, then attack_lineup with leader true on each map ... come back daily to improve and attack again,' naming the exact sibling tools and the parameter value to use. The reset cadence (Sunday 08:00 UTC) tells the agent when the state changes and a refresh is worthwhile.

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