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

No annotations exist, so the description carries the full behavioral disclosure burden — and it excels. It reveals asynchronous background embedding ('_finalize_save_bg'), the transient WARM tier state with embedding=NULL until backfill, retrievability-by-text during that window, blocking trigram dedup versus non-blocking semantic dedup (>0.9 logs only), auto-link behavior (>0.75 threshold), and the critico flag's lifetime protection semantics. This is rich operational detail an agent needs to predict side effects.

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 long but information-dense and well-organized: a front-loaded behavioral summary precedes a structured Args block with per-parameter detail. Nearly every sentence earns its place given the 0% schema coverage and the tool's genuine complexity. Minor trimmable details like the internal function name '_finalize_save_bg' and the 'Returns' line (redundant with the output schema) keep it from a 5.

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 high-complexity tool (9 params, async behavior, dedup logic, retention tiers, side-effectful auto-linking), the description covers parameters, behavioral states, side effects, duplicate handling, and returns. Small gaps remain: error conditions are unspecified, memory_type lists only 'valores comunes' without stating whether other values are accepted, and there is no guidance on content-length limits. These are minor against an otherwise thorough definition.

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% — the schema provides only parameter titles with no descriptions. The description fully compensates by documenting all 9 parameters with defaults, semantics, and concrete examples: memory_type values ('event', 'decision', 'profile'), code examples ('documentacion', 'bugfix'), categories, nivel hierarchy, and force/critico behavior. Every parameter an agent needs to understand is explained with actionable detail.

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 opening line 'Guarda un recuerdo en el Hipocampo (memoria_vectorial)' names a specific verb (save/insert) and a specific resource (a memory into the vector store). The description goes further to refine purpose by delineating the exact write semantics: immediate, non-blocking insert with background embedding. Against a sibling set containing update_hipocampo, delete_hipocampo, link_hipocampo, and search_hipocampo, this is unmistakably the primary create/insert tool.

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 provides clear context about when a save will or won't happen: 'Si ya existe un recuerdo casi idéntico (trigram), se advierte y se omite el guardado a menos que force=True' tells the agent the call may be a no-op and how to override it. However, it never explicitly names alternatives for adjacent use cases (e.g., when to call update_hipocampo for modifying an existing memory instead, or search_hipocampo for retrieval). Context is clear but exclusions and alternative routing are absent.

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