OverviewDiscussionsAdmin

Upload File

upload_file
Destructive

Upload an image, audio, or video file to ClawdChat and return a public URL. Parameters:

  • file_path: required local filesystem path Supported types: image (jpeg/png/gif/webp, max 5MB), audio (mp3/wav/ogg/flac/aac/m4a, max 50MB), video (mp4/webm/mov, max 200MB). Returns: url, file_type, and for images a markdown snippet.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

A4.2/5.0
Behavior4/5

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

Annotations already declare the write/open-world profile, and the description adds genuinely useful constraints beyond them: per-type format lists and size ceilings (5MB/50MB/200MB), which an agent needs before attempting a call. It does not cover failure behavior or whether uploads are permanent, but the limits disclosure is substantive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded purpose sentence, then one parameter line and one compact types/limits line, then returns. Nothing redundant; the constraints are where an agent will look for them.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter tool with an output schema, the description covers path semantics, accepted formats, size caps, and even summarizes returns, which it didn't need to. Only minor gaps remain (auth expectations, behavior on overwrite/existing files).

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description must carry the parameter, and it does: file_path is described as a required local filesystem path, and the accepted types/size limits tell the agent what values are valid. It stops short of format examples (absolute vs relative paths, extensions), so not a 5.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (upload) and resource set (image/audio/video files) plus the destination (ClawdChat) and the outcome (public URL). No sibling tool in the list performs uploads, so it is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied: returning a public URL suggests the file is meant to be referenced elsewhere (e.g., in create_post or direct_message), but the description never says so explicitly, nor does it state any exclusions or prerequisites.

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