v0.2.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, so safety is covered structurally. The description adds genuine context by naming named-checkconf -z, which signals that zone files are actually loaded and parsed rather than just syntax-checked, and implies no mutation or reload occurs. It does not state whether errors are surfaced as findings or thrown, so the transparency gain is moderate.
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?
One short sentence, tag front-loaded, verb and resource immediately visible, and the concrete command appended as supporting detail. No filler.
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?
For a single-parameter validation tool with no output schema, the description explains what is checked and how, but leaves two things an agent needs: the meaning of 'target' and the shape of the result (pass/fail plus error list versus a raw command exit). Adequate but not complete.
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 never mentions the single 'target' parameter. An agent cannot tell from either source whether 'target' is a config file path, a directory, a server, or a zone name, nor what the null default means. With only one optional parameter this is a real gap rather than a minor one.
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: 'Validate BIND config and loaded zone files', and names the underlying mechanism (named-checkconf -z), which makes clear this is a static validation pass rather than a live query. It is distinguishable from most siblings such as bind_status or bind_query, though it does not explicitly differentiate itself from the closer bind_diagnose_zone or bind_compare_soa.
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?
No when-to-use or when-not-to-use guidance is given. The agent is not told whether to run this before bind_reload_zone, or how it relates to bind_diagnose_zone. The '[READ]' tag and the word 'Validate' only imply usage; nothing steers selection among siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
