Save project

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

Annotations declare readOnlyHint=false and idempotentHint=false, so safety profile is partly covered; the description adds valuable context by enumerating the mutation classes that get persisted and by stating that saving is never implicit. It does not describe failure modes, conflict behavior, or whether a save can be undone.

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?

Four short sentences, front-loaded with purpose and followed by scope, the explicit-save rule, and the confirmWrite prerequisite. Minor redundancy between 'Requires confirmWrite' and the schema's own const/description.

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?

With annotations and an output schema present, the description only needs to add behavioral context, which it does: what is persisted and the explicit-save contract. The remaining gap is its relationship to the project transaction lifecycle, which is left unaddressed.

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 100%, so both parameters are already documented in the schema; the description's mention that confirmWrite is required merely restates that constraint. Baseline 3 is appropriate since the schema does the heavy lifting.

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?

States a specific verb and resource ('Explicitly save the current EasyEDA Pro project') and enumerates what gets persisted (netlist changes, net flags, pin connections). It does not, however, differentiate itself from the closely related sibling easyeda_project_commit_transaction, which an agent would reasonably confuse with a persist operation.

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?

Gives clear context for when this tool is needed: 'Save is never implicit — the caller must explicitly request it,' which tells the agent it must be called after mutations. It stops short of naming alternatives or exclusions, notably the transaction tools (begin/commit/rollback) that could also persist work.

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