brightspace_archive_links

Archive Brightspace course content by navigating links from the active tab or a URL list, saving each page as categorized HTML and PDF with a manifest.

Instructions

Navigate through Brightspace links from the current tab or a provided URL list and save each page as a categorized manifest plus HTML/PDF.

TDQS

B3.1/5.0
Behavior2/5

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

With no annotations provided, the description must fully disclose behavior. It states navigation and saving but omits dependencies (Chrome debug URL, active tab requirement), the structure of the manifest, and side effects like file creation. It also fails to mention that delayMs, maxPages, and filtering parameters affect behavior, leaving significant behavioral ambiguity.

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?

The description is a single, front-loaded sentence with no filler. It efficiently conveys the core action and output without redundant phrasing, earning full marks for conciseness.

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

Completeness2/5

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

Given 12 parameters, no output schema, and no annotations, the description is too sparse. It provides a high-level flow but leaves critical context undocumented: filtering behavior (urlPattern, urlContains, titleContains), navigation limits (maxPages), timing (delayMs), and the structure of the output manifest. The tool cannot be reliably invoked without additional information.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must compensate. It provides minimal semantics: 'current tab' maps to tabId, 'URL list' maps to urls, and 'HTML/PDF' maps to saveHtml/savePdf. However, it does not explain outputDir, courseCode, urlPattern, urlContains, titleContains, delayMs, debugUrl, or maxPages, leaving most parameters semantically opaque.

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?

The description clearly states the tool navigates Brightspace links from the current tab or a URL list and saves each page as a categorized manifest plus HTML/PDF. This specific verb+resource+output distinguishes it from siblings like chrome_save_page or chrome_download_urls, which handle single-page downloads without manifest creation.

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

Usage Guidelines2/5

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

No explicit guidance on when to use this tool vs alternatives. It mentions two input modes (current tab, URL list) but does not discuss prerequisites such as a running Chrome debugger, nor exclusions like when to prefer brightspace_collect_current or chrome_save_page. The context is implied but not actionable.

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