Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds value beyond the readOnlyHint annotation by disclosing that secret variable values are redacted and providing the API endpoint. However, it does not mention pagination behavior or other relevant details like rate limits or empty responses.
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 sentences, front-loaded with the core purpose, followed by a relevant caveat. No wasted words.
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 simple list tool with two optional parameters and no output schema, the description covers key points (scope, redaction) but lacks mention of return format or pagination details, which could be helpful.
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 coverage is 100% with clear descriptions for both parameters. The description does not add extra meaning beyond the schema, so baseline 3 is appropriate.
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 specifies a clear verb ('list') and resource ('account-level environment variables'), distinguishing it from sibling tools like 'checkly_create_variable'. It is precise and 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?
No guidance on when to use this tool versus alternatives (e.g., when to list variables vs create or update). The only caveat is about secret values being redacted, but no explicit when-not-to-use context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Most tools target distinct resources (checks, groups, results, statuses, etc.). However, `checkly_get_check_alerts` vs `checkly_list_check_alerts` could be confused, though descriptions help clarify per-check vs account-level.
All tools follow a consistent `checkly_verb_noun` pattern, using `get`, `list`, and `create` appropriately. No mixing of styles.
22 tools cover a broad monitoring domain reasonably well, but a few resource types (e.g., dashboards, snippets, runtimes) with only list operations may be underutilized.
The tool set is heavily read-only; only maintenance windows and variables have create operations. Missing create/update/delete for checks, groups, alert channels, and other core resources, limiting agent ability to manage the account.
