cache_design_strategy

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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. The description mentions the design areas (TTL policies, cache layers, eviction rules) but says nothing about expected outputs, whether it generates configuration files, returns a plan, requires prior context, or has side effects. For an advisory/design tool this is a significant gap.

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 a single concise sentence that front-loads the main purpose and names three concrete aspects. There is no filler or repetition, though it is arguably under-specified rather than improperly verbose.

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 design/strategy tool with no annotations and no output schema, the description is incomplete. It does not clarify what the output will be (e.g., a generated document, code, configuration), what constraints shape the strategy, or what the agent should do after invoking it. The schema parameters help, but the overall behavioral contract is unclear.

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 100%, so the baseline is 3. The description itself does not add parameter-level detail beyond naming TTL, layers, and eviction rules, which only loosely maps to the `resources`, `consistency`, and `read_write_ratio` parameters. It does not explain how the design decisions are derived from these inputs, but the schema already documents each parameter adequately.

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 'Design a caching strategy with TTL policies, cache layers, and eviction rules' clearly identifies the resource (a caching strategy) and the key design dimensions (TTL, layers, eviction). It is distinct from siblings like cache_generate_redis or redis_setup_caching, which imply actual cache implementation rather than strategy design, though it does not explicitly distinguish itself from those.

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 guidance is given about when to use this tool versus alternatives such as cache_generate_redis, gha_add_caching, or redis_setup_caching. The description only states what it does, not the context in which it is the preferred choice (e.g., designing a strategy before implementation) or when to use alternatives.

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