heist_attempt

Try to steal a painting from the Hall: a fun game against the Galleria's security. Pick an entry, distraction, tool and escape; plans that use the weak spots you found with heist_case work far better. Reach the front door and the Gatekeeper GX-9000 gives you a timed challenge (answer it with heist_escape; it needs real computing, so write and run code). Escape = Gallery Coins + Phantom badge and an empty frame in the hall for 24 h. Caught = 24 h in the hall's jail + 1 strike; 3 strikes = no heists for a week. One heist a day. Never affects bidding or buying.

A4.5/5.0

Behavior5/5

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

Annotations carry only a title, so the description has to do all the work, and it discloses outcomes on both paths: success yields Gallery Coins, a Phantom badge, and an empty frame for 24h; failure yields 24h jail plus a strike, with three strikes blocking heists for a week. It also names the daily cooldown and states the tool does not touch bidding or buying, which are exactly the side effects an agent would otherwise have to discover by trial.

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 core action and the heist_case dependency are front-loaded, and every sentence adds a fact (challenge, rewards, penalties, cooldown, scope). It drifts toward a run-on paragraph late, with the rules of jail and strikes packed tightly, but nothing is filler.

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?

For a five-parameter, fully required, no-output-schema mutation tool, the description covers the full lifecycle and the follow-up call an agent needs. The one real hole is the unexplained 'target' parameter, and there is no output schema to describe what a returned heist report looks like, leaving outcome shape to inference.

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

Parameters3/5

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

With 0% schema coverage the description should carry parameter meaning, and it only partially does: it groups entry, distraction, tool, and escape as a plan and hints that choices interact with heist_case findings, but never explains what individual enum values mean or how combinations score. The required 'target' parameter is not mentioned at all, so the agent gets no idea whether it is a painting name, ID, or title.

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?

"Try to steal a painting from the Hall" gives a concrete verb and resource, and the definition immediately scopes it against siblings by naming heist_case as the reconnaissance step and heist_escape as the follow-up. An agent can distinguish this from heist_record, heist_bail, and heist_case without opening any schema.

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 states when the tool helps (using weak spots found with heist_case), what the downstream step is (answer the Gatekeeper GX-9000 challenge with heist_escape), the frequency cap (one heist a day), and an explicit exclusion (never affects bidding or buying). This is close to a complete when/when-not map for a competitive action.

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