vts_admin

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

With no annotations, the description carries the burden of behavioral disclosure. It does reveal important traits: VCS commands are READ-ONLY, output is compacted, mutations are refused, and discover targets code searches that BYPASSED vts. However, it does not disclose side effects or persistence behavior for setup, config, savings_reset, or gen_compile_db{apply,...}, which are potentially mutating operations.

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 dense but efficient, front-loading the core 'rarely needed reflexively' warning before enumerating operations. The grouping and examples pack substantial information into a compact space, though the telegraphic separators and brace syntax like savings{graph|daily|history} require careful parsing.

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?

Given the high complexity of a 12-op dispatcher with nested params and no output schema, the description provides a solid overview and several examples but leaves gaps. Sub-op syntax for savings/discover/gen_compile_db is not fully specified, return values are not described, and side effects for several mutating-looking operations are omitted. It is adequate for orientation but not fully self-sufficient.

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?

The schema provides only an op enum and a generic params object, so the description adds real meaning by explaining the calling convention: 'set op, put that op's args in params'. Concrete examples such as {"argv":["status"]} and {"since":30} clarify the expected param shape beyond what the schema alone provides.

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 names the resource ('vs-token-safer') and the function ('admin/meta ops'), then enumerates concrete operations such as setup, index, discover, git, and p4. It is clearly distinguishable from the sibling code-manipulation tools, especially by the 'rarely needed reflexively' framing. It is a multi-op dispatcher rather than a single-verb tool, so it misses a 5 slightly.

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 description gives concrete when-to-use context: admin/meta setup, index building, discovery of bypassed searches, and executing READ-ONLY VCS commands. It also explicitly warns that mutations are REFUSED for git/p4, and 'rarely needed reflexively' discourages using this tool as a default. It does not name sibling tools explicitly, but the usage boundaries are clear enough.

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