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

With no annotations, the description carries full burden. It discloses auto-detection of source, three checks, return fields (flags, totals, URL), and constraints (max rows, max size). It lacks explicit statement about read-only nature but since it's analysis-only, it's adequate.

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 front-loaded with core action and checks, followed by input details and usage prompts. While verbose, each sentence serves a purpose. Minor reduction could improve conciseness but structure is logical.

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?

Given no output schema, the description sufficiently covers return values (flags, totals, URL) and constraints. It answers key agent questions about input format, limits, and typical use cases. Lacks details on severity levels but otherwise complete for an analysis 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?

Schema coverage is 100% and baseline is 3. The description adds significant value beyond schema descriptions by detailing supported accounting software, required row structure, and auto-detection logic. The fileName parameter is clarified as optional label input.

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 takes a Balance Sheet CSV and runs three specific checks (equation broken, negative asset, negative equity). It uniquely identifies the resource and verb, and distinguishes from sibling tools like analyze_profit_loss by focusing on balance sheet analysis.

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?

The description explicitly lists example user queries that trigger use this tool, such as 'does my balance sheet balance?' and 'is my company solvent?'. It also warns about downstream invalidity if equation fails. However, it does not contrast with sibling tools like analyze_trial_balance or state when not to use, preventing a perfect score.

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

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

With no annotations, the description fully discloses behavior: auto-detection of source, aggregation logic, materiality thresholds (≥5%, ≥100), severity levels, row/ size limits, and return type. No contradictions.

It also mentions per-user pricing, free tier, trial, and enterprise. No behavioral traits are hidden.

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 packed with useful information but is relatively long. It front-loads the core function, then distinguishes from siblings, then provides pricing and usage details. Each sentence adds value, though slight trimming could improve conciseness.

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?

With no output schema, the description fully explains return values: full matrix or per-region status/pricing/competitor frame. It also covers pricing model, free tier, trial, and roadmap. The tool has only one optional parameter, and all relevant details are covered.

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 description coverage is 100% (country parameter documented with enum and description). The description adds significant context beyond the schema, such as 'US is shipped; the other 7 are roadmap as of 2026-06-12' and explains behavior when omitted vs. provided.

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 returns HelloCPA Practice Management info, specifies the standalone product at practice.hellobooks.ai, lists features, and distinguishes it from the Partner Program and plan tiers. The verb 'Return' plus explicit resource makes purpose unmistakable.

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?

The description explicitly says when to use it (for Practice Management info) and what it is NOT (not Partner Program, not a plan tier). It provides guidance on calling without args for full matrix or with country for one region, and references sibling tools like list_plans and partner_program_info indirectly.

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