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

With no annotations at all, the description carries the full burden, and it does disclose one real behavioral trait: the operation is audited. It does not say whether re-aligning removes the initiative from its previous objective, what permissions are required, or whether the title overwrite is reversible, leaving meaningful mutation risk undocumented.

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?

Two short sentences, zero padding, with the primary operation front-loaded and the audit note kept to a terse trailing fragment. Nothing is repeated from the schema or title.

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?

An output schema exists, so return values need not be explained, and the 100%-covered schema handles parameter detail. But for a mutation tool with no annotations, the description omits the side-effect profile (does it unlink from the old objective? does an empty title clear it?), which is the one thing an agent cannot get from structured fields.

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% and the schema already documents the subtle cases (objective_id empty string unaligns, key_result_id implies its objective). The description only restates the align/rename intent at a high level, adding essentially nothing the schema does not already say, so baseline 3 applies.

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 a specific verb set (re-align / rename) against a specific resource (initiative), so an agent knows exactly what mutation it performs. It stops short of explicitly distinguishing itself from siblings like memory_strategic_initiative_set, but the update semantics are unambiguous.

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?

It states what the tool does but never states when to choose it over memory_strategic_initiative_set or memory_strategic_key_result_update. No prerequisites, no exclusions, no alternatives are named, so the agent must infer usage from the verb alone.

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