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

With no annotations supplied, the description carries the full burden and does disclose meaningful traits: the operation is idempotent, the target database is archive_catalog, and the created tables are sets, tars and entries. It also mentions a visible side effect (it 'shows the tables'). However, it says nothing about required credentials/permissions, what happens if an incompatible schema already exists, or whether existing data is preserved.

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: the action, the parenthetical detail of database and tables, then the idempotency and the table-listing side effect. Every clause carries information, though the trailing 'and shows the tables' reads as an afterthought that could be phrased more cleanly.

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 zero-parameter, no-output-schema, unannotated tool the description covers the core action and its main behavioral property (idempotency). It stops short of the operational details an agent would want before invoking an initialization step — permission requirements and handling of a pre-existing divergent schema.

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 tool takes zero parameters, so there is no parameter semantics to explain and the baseline of 4 applies. The description instead spends its words on target resources, which is the correct trade-off here.

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 gives a specific verb and resource — 'Creates the file catalogue schema' — and names the concrete backing store and tables (MySQL database archive_catalog: sets, tars, entries). That is enough to distinguish it from catalog_drop and catalog_restore, though it never explicitly contrasts itself with the sibling migrate/restore tools.

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?

Usage is only implied: the word 'idempotently' signals it is safe to run on an uninitialized or already-initialized database, which suggests first-run setup. There is no explicit statement of when to prefer this over catalog_migrate or catalog_restore, and no prerequisites are listed.

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