Read a text file

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

With no annotations, the description carries the burden of disclosing side effects. The term 'Read' inherently implies a non-destructive operation, and the description does not suggest any modification. It could be more explicit about being read-only, but the intent is clear.

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 description is concise, consisting of two sentences with no redundant information. It efficiently conveys the core functionality and a key usage hint.

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?

Covers the essential purpose and the truncation behavior, which is sufficient for a simple read operation. It does not specify the return format, but since no output schema is provided, the absence is not critical; the description meets the needs for a basic tool.

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?

The description adds meaning for startLine and endLine by explaining they serve for paging through truncated files. However, it does not elaborate on filePath or projectId, which are presumably self-explanatory in the Overleaf context, but the schema itself provides no descriptions. Partial coverage.

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 clearly states the tool reads a LaTeX or other text file, which is specific and unambiguous. It naturally distinguishes from sibling tools like write_file, edit_file, and grep, as reading is a distinct operation.

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?

Provides actionable guidance by noting that long files are truncated and advising to use startLine and endLine for paging. This directly helps the user handle large files, though it does not explicitly mention when to prefer this over alternatives, which is not critical for a read operation.

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