get_constraints_summary

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Summarize' without explaining whether a project must be open, whether files are read from disk, whether this is read-only, or what happens with invalid constraint inputs. This is too thin for a tool with no annotation safety signals.

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 a single concise sentence with no filler words and is front-loaded with the action verb. It is efficient, though arguably too sparse to fully carry the tool's meaning.

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?

While the tool appears simple with no required parameters and has an output schema, the overall definition is incomplete: it provides no parameter semantics, no usage guidance, and no behavioral context. An agent selecting between this and several timing/constraint siblings would not have enough information to confidently 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?

Schema description coverage is 0%, and the description does not explain either parameter. 'fileset' could be guessed to relate to XDC files, but its exact format, required vs optional behavior, and relationship to 'timeout_s' are entirely undocumented. The description fails to compensate for the schema gap.

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 identifies the verb 'Summarize' and the resources it operates on: XDC files, ports, clocks, and common constraint commands. While this distinguishes it from timing-specific siblings like get_timing_summary, it does not explicitly differentiate it from check_timing_constraints or analyze_timing_closure.

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?

There is no guidance on when to use this tool versus its many siblings such as get_timing_summary, check_timing_constraints, or analyze_timing_closure. The description only implies a use case but does not state prerequisites, exclusions, or alternative selection logic.

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