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

Annotations already cover safety (readOnly, idempotent, non-destructive, closed-world), so the bar is lower, yet the description adds real behavioral context: results are summarized, exit tools log only counts/flags/statuses rather than answer contents, and there is an explicit 'don't send personal data or secrets' guardrail. The caveat 'a reviewed playbook is not a completed customer migration' also usefully frames expectations. The data-storage paragraph reads partly as shared boilerplate rather than tool-specific behavior, which keeps it from a 5.

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 core definition is front-loaded and dense, but the long parenthetical on stored arguments, hashing, and billing sources is verbose boilerplate that does not help select or invoke this specific tool. Roughly half the description is generic service-level privacy prose.

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?

With no output schema, the description carries the return-content burden and does so well by enumerating the runbook sections. Safety is covered by annotations and data-handling by the privacy paragraph, so an agent has what it needs, though the absence of any error/not-found or size caveat leaves a small gap.

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 single id parameter is fully documented with format and an example, so parameter_semantics sits at the baseline. The description adds only that the runbook comes from search_workflow_recipes, which the schema already states, and gives no extra guidance on id validity or failure behavior.

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 states exactly what is returned: one runbook from search_workflow_recipes retrieved in full, and enumerates its parts (decisions, ordered steps, acceptance tests, rollout, rollback, maintenance, templates with digest). It clearly distinguishes itself from the search sibling search_workflow_recipes, so an agent can route without opening schemas.

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 implied: fetch a full recipe by id after surfacing it via search_workflow_recipes, and the schema reinforces this ('Workflow id from search_workflow_recipes'). However, there is no explicit when-to-use vs. when-not, and no comparison against near siblings like get_recipe, get_exit_plan, or get_build_packet despite the crowded namespace.

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