reply

Initiates a reply to a buffered decode, starting a QSO transmission in WSJT-X. Use the decode's sequence number or exact message to trigger the response.

Instructions

Answer a buffered decode — initiates a transmission (gated by callsign).

Equivalent to double-clicking that decode in the Band Activity window. WSJT-X only acts if the message exactly matches a prior decode that is a CQ or QRZ. If WSJT-X's "Auto Seq" is on (the usual FT8/FT4 default) it then sequences the rest of the QSO to completion on its own; if Auto Seq is off this starts only the first transmission (Auto Seq is a UI setting, not UDP-controllable).

Identify the decode by seq (from the decodes tool) or by exact message text (the most recent matching buffered decode is used). modifiers may be a name or list (shift, ctrl/cmd, alt, meta, keypad, group) to mimic modifier-clicks.

Behavior5/5

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

With no annotations provided, the description fully carries the burden of disclosing behavioral traits. It explains that the tool only acts if the message exactly matches a prior CQ or QRZ decode, describes the Auto Seq behavior (sequences QSO or starts first transmission), and notes that Auto Seq is a UI setting. This is comprehensive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise yet complete, using bold for key terms and bullet-like structure. Every sentence adds value: first sentence states purpose, second clarifies equivalence, third explains Auto Seq, fourth details parameter usage. No redundant or fluff content.

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?

Given the complexity (4 parameters, no output schema, 0% schema coverage), the description covers all necessary aspects: purpose, triggering conditions, parameter usage, and behavioral nuances (Auto Seq, modifiers). It references a sibling tool ('decodes') and explains the context of buffered decodes. No major gaps.

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?

Despite 0% schema description coverage, the description compensates well for most parameters. It explains 'seq' and 'message' in detail (identify from decodes, matching logic) and 'modifiers' (values like shift, ctrl, alt). The 'instance' parameter is not mentioned, leaving a small gap. Overall adds significant meaning beyond 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?

The description clearly states the tool's purpose: 'Answer a buffered decode — initiates a transmission (gated by callsign).' It uses a specific verb ('answer') and resource ('buffered decode'), and distinguishes itself from siblings like 'free_text' and 'transmit' by specifying it's equivalent to double-clicking a CQ/QRZ decode.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context on when to use the tool: when you have a decode from the 'decodes' tool and want to reply. It explains how to identify the decode (by seq or message) and mentions modifiers. However, it lacks explicit exclusions or references to alternative tools for different use cases (e.g., sending arbitrary text with 'free_text').

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