Merge Reaction Schemes

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, and it discloses almost nothing. It doesn't state whether input files are modified or left untouched, whether output_path creates a new file or overwrites, what the rendering behavior is, whether the operation is reversible, or any side effects. 'Merge' hints at a combining operation but nothing about the mutation or output semantics.

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?

A single front-loaded sentence with zero filler, which is easy to parse. However, the brevity is a symptom of under-specification rather than efficient compression — the sentence is short because it omits nearly all operational detail. Acceptable as conciseness, but the structure earns no credit for covering meaningful content.

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 8 parameters, 0% schema coverage, no annotations, and no output schema, this single sentence is materially inadequate. An agent cannot determine valid mode values, equivalence behaviors, output handling, or what the preview/reference options do. For a tool this parameterized and complex, the description should offer far more operational context.

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%, so the description must compensate for the 8 parameters, and it explains none of them. None of mode, equiv_mode, input_paths, output_path, allow_adjacent, render_preview, reference_cdxml, or force_sequential are mentioned, leaving the agent to guess what these mode toggles and flags mean. This is a serious gap for a tool with two mode-style parameters.

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 ('Merge'), a specific resource ('CDXML reaction schemes'), and the scope ('parallel, sequential, or unrelated'). This clearly distinguishes the operation from siblings like clean_scheme_layout, polish_reaction_scheme, and segment_large_scheme, which perform different transforms on schemes. It's not a tautology and names the file format explicitly, so an agent can tell roughly what it does.

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?

The phrase 'parallel, sequential, or unrelated' gives a weak hint about when merging applies, but there is no explicit when-to-use guidance, no exclusions, and no mention of alternatives among the many scheme-related siblings (parse_scheme, segment_large_scheme, render_scheme, etc.). An agent has no signal about when to choose merge over a sibling that parses or renders a scheme instead.

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