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

Annotations already flag destructiveHint=true and openWorldHint=true, but the description goes further: re-uploading the same path overwrites it, only static file types are accepted, .php/.htaccess are rejected, size is capped at 1 MB per call, and nothing is published. That is exactly the kind of destructive/limit/auth context annotations cannot express.

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?

It is a dense single block, but every clause carries an actionable constraint and the core purpose is front-loaded. Slight deduction for the wall-of-rules formatting that makes scanning harder, though nothing is truly filler.

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?

No output schema exists, and none is needed: the description explains that loading only stages the file and that deploy_publish finalizes, covering the 'what happens next' an agent needs for a write tool with a 5-param schema.

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%, so baseline would be 3, but the description adds substantial meaning the schema lacks: path character set and forbidden patterns (umlauts, spaces, hidden files, _tp/), the allowed file-type whitelist, examples of valid paths, and the mapping rule for encoding (utf8 for text formats, base64 for binaries).

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?

States a specific verb+resource+scope: 'Lädt eine Datei in einen offenen Deploy (aus deploy_begin)'. It ties itself to a specific lifecycle stage and even rules out the sibling path with 'Bilder aus dem Netz stattdessen mit deploy_import_asset laden'. An agent can distinguish it from deploy_import_asset, deploy_git and deploy_publish without opening a schema.

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?

Gives explicit when-to-use ('Pro Datei ein Aufruf'), the alternative and its condition (web images via deploy_import_asset rather than hotlinking), and an explicit exclusion about the publish step ('Veröffentlicht NICHTS – das macht erst deploy_publish nach Bestätigung durch den Nutzer'). This is close to a routing rule, not just background.

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